REPORTING CURRENCY, FINANCIAL AND OTHER INFORMATION

All amounts in this Report are expressed in US dollars, unless otherwise indicated. Canadian currency is denoted as “Cdn$” and the Euro is denoted as “€”.

Financial information is presented in accordance with accounting principles generally accepted in Canada (“Cdn GAAP”). Differences between accounting principles generally accepted in the US (“US GAAP”) and those applied in Canada, as applicable to Golden Star Resources Ltd., are explained in Note 22 to the Consolidated Financial Statements.

Information in Part I and II of this report includes data expressed in various measurement units and contains numerous technical terms used in the gold mining industry. To assist readers in understanding this information, a conversion table and glossary are provided below.

References to “Golden Star”, “we”, “our”, and “us” mean Golden Star Resources Ltd., its predecessors and consolidated subsidiaries, or any one or more of them, as the context requires.

NON-GAAP FINANCIAL MEASURES

In this Form 10-K, the terms “total cash cost” and “cash operating cost” is used on a per ounce of gold basis. Total cash cost per ounce is equivalent to mining operations expense for the period as found on the consolidated statements of operations, divided by the number of ounces of gold sold during the period. Cash operating cost per ounce is equivalent to mining operations expense for the period, less production royalties, divided by the number of ounces of gold sold during the period.

We have included total cash cost and cash operating cost information to provide investors with information about the cost structure of our mining operations. We use this information for the same purpose and for monitoring the performance of our operations. This information differs from measures of performance determined in accordance with GAAP in Canada and the US and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. These measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP and might not be comparable to similarly titled measures of other companies. See Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations for a reconciliation of these non-GAAP measures to our Statement of Operations.

PART I

ITEM 1. DESCRIPTION OF BUSINESS

OVERVIEW OF GOLDEN STAR

Golden Star Resources Ltd. was established under the Canada Business Corporations Act on May 15, 1992 as a result of the amalgamation of South American Goldfields Inc., a corporation incorporated under the federal laws of Canada, and Golden Star Resources Ltd., a corporation originally incorporated under the provisions of the Alberta Business Corporations Act on March 7, 1984 as Southern Star Resources Ltd. We are a Canadian international gold mining and exploration company producing gold in Ghana, West Africa. Our principal office is located at 10901 West Toller Drive, Suite 300, Littleton, Colorado 80127, and the registered and records office is located at 19th Floor, 885 West Georgia Street, Vancouver, British Columbia, Canada V6C 3H4. Our fiscal year ends on December 31.

Through our subsidiaries and joint ventures we own a controlling interest in four significant gold properties in Southern Ghana: the Bogoso property (“Bogoso”), the Prestea property (“Prestea”), the Wassa property (“Wassa”) and the Prestea Underground property (“Prestea Underground”). Bogoso and Prestea are adjoining properties, operating as a single operation and referred to as “Bogoso/Prestea”. Bogoso/Prestea and the Prestea Underground are owned by our 90% owned subsidiary Bogoso Gold Limited (“BGL”). In 2003 Bogoso/Prestea sold 174,315 ounces of gold for an average gold price and cash operating cost of approximately $364 and $166 per ounce, respectively. Bogoso/Prestea has produced all of our gold since initiating production in late 1999.

We hold a 90% equity interest in Wexford Goldfields Limited (“WGL”), which owns the Wassa gold property, located some 35 kilometers east of Bogoso/Prestea. Wassa is currently in development, and we expect gold production to commence in early 2004.

The Prestea Underground is located on the Prestea property and consists of a currently inactive underground gold mine and associated support facilities. As of December 31, 2003 BGL owned an approximately 66% operating interest in this mine and we are currently seeking to determine if the underground mine can be reactivated on a profitable basis.

We also hold interests in gold exploration properties in Ghana, Sierra Leone, Mali, Suriname, and French Guiana. The French Guiana properties are mainly held through our 73%-owned subsidiary, Guyanor Ressources S.A. (“Guyanor”). We hold a royalty right on the Gross Rosebel gold mine in Suriname and expect to begin receiving cash royalties from this property during 2004.

Most of our senior corporate management reside in Littleton, Colorado where we maintain our corporate headquarters. In addition to the Bogoso/Prestea and Wassa employees, we have a small administrative office and staff in Accra, the capital of Ghana, and a small staff in French Guiana where most of our South American exploration properties are located. Our accounting records are kept in compliance with Canadian GAAP and all of our operations, except for the French Guiana office, transact business in US dollars and keep financial records in US dollars.

Gold Sales and Production

Ghana has been a significant gold producing country for the last 100 years with Ashanti Goldfields Company Limited’s Obuasi mine and the underground mine at Prestea historically being the two major producers. Several other areas in Ghana have also produced significant amounts of gold. The gold industry in Ghana is currently experiencing resurgence in exploration, development spending and gold production. Several large international gold mining companies have announced in the past year plans to spend several hundred million dollars on exploration and expansion projects in Ghana. Gold production in Ghana exceeded 2 million ounces in each year from 1998 through 2002, reaching approximately 2.2 million ounces in 2002. Gold production in Ghana is projected to rise in the future as the planned developments and expansions reach the production stage.

All of our gold is sent to a South African gold refinery in the form of doré bars which average approximately 91% gold with the remaining portion being primarily silver which we account for as a by-product. Our gold is sold to a

European bank and revenue is recognized when title is transferred to the customer at the Accra International Airport in Ghana. The sales price is based on the London P.M. fix on the day of delivery.

Gold Price History

The price of gold is volatile and is affected by numerous factors beyond our control such as the sale or purchase of gold by various central banks and financial institutions, inflation or deflation, fluctuation in the value of the US dollar and foreign currencies, global and regional demand, and the political and economic conditions of major gold-producing countries throughout the world.

BUSINESS STRATEGY AND DEVELOPMENT

Our business and development strategy since 1999 has been to focus primarily on the acquisition of producing and development stage gold properties in Ghana and on the exploration, development and operation of these properties. Given our significant mineral resource position, we are currently carrying out technical studies to expand our production at Bogoso/Prestea. At our Wassa property, we commenced development in mid-2003, and now expect to commence production in early 2004 by processing material from the existing heap leach pads left by the former owner. We plan to commence ore production from the Wassa open pit mine in early 2005. If the above mentioned expansion and development plans are approved and permitted (as expected), our annualized production should exceed 350,000 ounces of gold. However, there can be no assurance that development and start-up can be completed as anticipated or that our production goals will be achieved.

Our objective is to grow our business to become a mid-tier gold producer (which we understand to be a producer with annual production of approximately 500,000 ounces) over the next few years. Due to higher gold prices and our improved financial condition, we believe we are well placed to pursue the acquisition of producing, development and advanced stage exploration gold properties and companies, primarily in Ghana and elsewhere in Africa. We are actively investigating potential acquisition and merger candidates, some of which have indicated to potential acquirers or their advisors that they or certain of their properties might be available for acquisition. However, we presently have no agreement or understanding with respect to any potential transaction. We have increased exploration activities and expenditures on our current exploration properties, primarily in Ghana.

OUR ASSETS

Bogoso/Prestea — As mentioned above, we own and operate the Bogoso/Prestea gold mine in Ghana, West Africa. Ore is currently mined from an open-pit surface operation at Prestea and trucked approximately 15 kilometers from the Prestea mine site to the nominal 6,000 tonne-per-day Bogoso processing plant where the ore is processed. The Bogoso processing plant utilizes CIL technology along with gravity and flotation processes to separate gold from the ore. CIL technology is well known and is widely used for treating gold ores. In addition to the mine and processing plant facility, our assets include a fleet of mining equipment, numerous ancillary facilities including warehouses, maintenance shops, roadways and administrative offices. We also own several housing complexes at Bogoso which include a medical center, cafeteria, store, recreation facility and golf course.

Under normal operating conditions and current processing capacity, Bogoso/Prestea would produce approximately 130,000 to 140,000 ounces per year; however in 2003 we sold 174,315 ounces due primarily to higher than average ore grades and improved recoveries. Historical and forecast production from Bogoso/Prestea are shown on the Gold Production and Cash Costs table below.

Wassa — Once Wassa’s development and construction are completed in 2004, it will be very similar to Bogoso/Prestea including an open-pit surface mine, a CIL processing plant, mining equipment and a town site with associated facilities.

Prestea Underground — The Prestea Underground is located directly beneath the Prestea property. It is a large underground gold mine that operated for over 100 years producing a total of approximately nine million ounces of gold prior to its closure in early 2002. We have entered into a joint venture with the previous owner and are now performing engineering, geological and economic analysis of the mine to determine if it can be reopened on a profitable basis. The mine includes two useable shafts and several kilometers of underground workings on numerous levels extending as deep as 1,400 meters below the surface.

Other Assets — We hold or have an interest in numerous exploration properties in Ghana, Sierra Leone, Mali, and South America. Most of the exploration properties in Ghana are within trucking distance of Bogoso/Prestea or Wassa. The Mampon property, located approximately 35 kilometers north of the Bogoso processing plant, has

Table of Contents

mineral reserves of approximately 0.2 million ounces which are expected to be trucked to the Bogoso processing plant after 2005. We have a staff of geologists in Ghana that are actively investigating the mineral resource potential of the various exploration properties, and we anticipate that such exploration effort will increase in 2004.

GOLD PRODUCTION AND CASH COSTS

The following table represents historical gold production and projected production for 2004.

(1) The 2004 projection for Bogoso/Prestea excludes any impact from the planned installation of the Bondaye processing plant at Prestea, which subject to approvals and permitting, is expected to be completed by early 2005.

(2) Wassa is expected to begin production by reprocessing materials, left on heap leach pads by a former owner, in early 2004, subject to the timely receipt of the necessary operating permits and the commissioning of the CIL processing plant which are progressing on schedule.

(3) Gold production is shown on a 100% basis, which represents our current beneficial interest in gold production and revenues. Once all capital has been repaid, the Government of Ghana would receive 10% of the dividends from the subsidiaries owning the Bogoso/Prestea and Wassa mines.

MINERAL RESERVES

Our proven and probable mineral reserves are estimated in conformance with definitions set out in Canada’s National Instrument 43-101. We have filed on SEDAR (www.sedar.com) Technical Reports on our mineral reserves for Bogoso/Prestea and Wassa as required in Canada’s National Instrument 43-101. We intend to file Technical Reports on our mineral reserves for Bogoso/Prestea and Wassa as of December 31, 2003 during the first quarter of 2004. See our “Glossary of Terms”. The proven and probable mineral reserves are those ore tonnages contained within engineered pits, using current and predicted mining and processing methods, and related operating costs and performance parameters. We believe that the definitions of proven and probable mineral reserves are consistent with the definition of proven and probable mineral reserves prescribed for use in the US by the US Securities and Exchange Commission and set forth in SEC Industry Guide 7.

The estimation of the mineral reserves is based on information compiled and/or validated by Mr. Dave Alexander, our Projects Planning Manager. Mr. Alexander is a qualified mining engineer with 20 years of experience, a member of the Institute of Materials, Minerals and Mining, and a Chartered Engineer under the auspices of the Engineering Council of the United Kingdom. Mr. Alexander is considered a qualified person under Canada’s National Instrument 43-101.

The proven and probable mineral reserves as of December 31, 2003 have been estimated at an economic cut-off grade based on a gold price of $325 per ounce. This compares to $300 per ounce used for the estimate of our mineral reserves at December 31, 2002.

Table of Contents

The following table summarizes total and our share of estimated proven and probable mineral reserves as of December 31, 2003 and December 31, 2002:

Notes to Proven and Probable Mineral Reserves Table

(1) Tonnes of mineral reserves are net of a 5% dilution allowance for mining to account for losses resulting from planned mining methods, and a 98% ore recovery factor.

(2) Calculation of contained ounces includes adjustments due to rounding.

(3) Approximately 68% of the 2003 Bogoso/Prestea mineral reserves are refractory ore. We are currently planning to add a bio-oxidation circuit to the Bogoso processing plant to process the refractory mineral reserves. The estimated recovery rates utilized in our mineral reserve calculations in 2003 ranged from 65% to 85% for oxides and other non-refractory ores, and from 78% to 85% for refractory ore. The estimated cut-off grades utilized in mineral reserve calculations in 2003 ranged from 0.7 g/t to 1.8 g/t for oxide ore and other non-refractory ores and from 1.5 g/t to 2.3 g/t for refractory ore. Included in the December 31, 2003 proven mineral reserve category is 0.8 million tonnes of ores at an average grade of 2.4 g/t in stockpiles which are located at Bogoso. Also included in the December 31, 2003 probable mineral reserve category are the Mampon property mineral reserves of 0.9 million tonnes of ore at an average grade of approximately 5.6 g/t containing approximately 162,000 ounces of gold. These mineral reserves were purchased as part of the Dunkwa properties acquisition in June 2003.

(4) All of the Wassa mineral reserves are non-refractory and should be treatable in the Wassa CIL processing plant now under construction. The estimated recoveries utilized in mineral reserve calculations in 2003 ranged from 92% to 93%. The estimated cut-off grades utilized in mineral reserve calculations in 2003 range from 0.5 g/t to 0.6 g/t. The mineral reserves include 4.2 million tonnes of material grading 0.7 g/t remaining on the leach pads established by the previous operator of the Wassa mine. No mineral reserves were declared for Wassa in 2002.

Table of Contents

Notes to Reconciliation of Proven and Probable Mineral Reserves Table

(1) Depletion represents contained ounces of mineral reserves processed during 2003 before considering recovery losses and therefore does not equal 2003 gold production.

(2) Increases and decreases in mineral reserves can result from the discovery of new mineralization, conversion of mineral resources to mineral reserves, changes in price assumptions, unit costs and recoveries or any combination of these factors. The increases in mineral reserves during 2004 were due primarily to the exploration successes at Bogoso/Prestea, the acquisition of the Dunkwa properties which included the mineral reserves at the Mampon property, and the successful completion of the feasibility study at Wassa.

NON-RESERVES — MEASURED AND INDICATED MINERAL RESOURCES

Measured and Indicated Mineral Resources

Cautionary Note to US Investors concerning estimates of Measured and Indicated Mineral Resources

This section uses the terms “measured mineral resources” and ‘indicated mineral resources”. We advise US investors that while those terms are recognized and required by Canadian regulations, the US Securities and Exchange Commission does not recognize them. US investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves.

Our measured and indicated mineral resources, which are reported in this Form 10-K, do not include that part of the mineral resources converted to proven and probable mineral reserves, and have been estimated in conformance with definitions set out in Canada’s National Instrument 43-101. We have filed on SEDAR (www.sedar.com) Technical Reports on our mineral reserves and mineral resources (mineral resources stated in the Technical Reports include mineral reserves) for Bogoso/Prestea and Wassa as required in Canada’s National Instrument 43-101. We intend to file Technical Reports for Bogoso/Prestea and Wassa as of December 31, 2003 during the first quarter of 2004. See our “Glossary of Terms”.

The measured and indicated mineral resources for our properties have been estimated at an economic cut-off grade based on a gold price of $375 per ounce for December 31, 2003 and economic constraints that we believe are realistic. For December 31, 2002 the economic cut-off grade was based on a gold price per ounce of $325, except at Yaou and Dorlin where we used a gold price of $300 per ounce.

The following table summarizes the total and our share of estimated non-reserves — measured and indicated mineral resources as of December 31, 2003 and December 31, 2002:

Notes to Non-Reserves — Measured and Indicated Mineral Resources Table

(1) See Glossary Of Terms for definitions of non-reserves — mineral resources, measured mineral resources and indicated mineral resources.

The estimation of the Bogoso/Prestea, Dunkwa and Wassa measured and indicated mineral resources are based on information compiled and/or validated by Mr. S. Mitchell Wasel, our Exploration Manager. Mr. Wasel is a qualified geologist who has 16 years of experience in gold and base metal exploration and is a member of the Australasian Institute of Mining and Metallurgy. Mr. Wasel is considered a qualified person under Canadian National Instrument 43-101.

The primary qualified person responsible for the estimation of the indicated mineral resource for the Dorlin property is Mr. Colin Jones, who is a professional geologist with 22 years of experience. Mr. Jones is a Partner and Manager (Audits) of RSG Global Pty Ltd and a member of the Australasian Institute of Mining and Metallurgy. Mr. Jones is considered a qualified person under Canadian National Instrument 43-101. The amount of the mineral resource at the Dorlin property that might have been removed by illegal mining is not known but could be material.

(2) Approximately 81% of the 2003 Bogoso/Prestea measured and indicated mineral resources are refractory. The estimated cut-off grades utilized in mineral resource calculations in 2003 ranged from 0.7 g/t to 1.8 g/t for non-refractory material and from 0.9 g/t to 2.1 g/t for refractory material. Also included in the December 31, 2003 indicated mineral resource category are mineral resources of 0.4 million tonnes of ore at an average grade of approximately 2.79 g/t, which were purchased as part of the Dunkwa properties acquisition in June 2003.

(3) All of the 2003 Wassa measured and indicated mineral resources are non-refractory. The estimated cut-off grades utilized in mineral resource calculations in 2003 ranged from 0.5 g/t to 0.6 g/t.

(4) Dorlin is located in French Guiana, South America, and Golden Star owns approximately an 86.5% beneficial interest of Dorlin. The estimated cut-off grades utilized in mineral resource calculations in 2003 was 0.5 g/t. The property is undeveloped and has been on a care and maintenance basis in recent years. In 2002 Yaou and Dorlin were reported together.

NON-RESERVES — INFERRED MINERAL RESOURCES

Inferred Mineral Resources

Cautionary Note to US Investors concerning estimates of Inferred Mineral Resources

This section uses the term “inferred mineral resources”. We advise US investors that while this term is recognized and required by Canadian regulations, the US Securities and Exchange Commission does not recognize it. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resources will ever be upgraded to a higher category. Under Canadian rules estimates of inferred mineral resources could not form the basis of feasibility or other economic studies. US investors

13

Table of Contents

are cautioned not to assume that part or all of the inferred mineral resource exists, or is economically or legally mineable.

Our inferred mineral resources, which are reported in this Form 10-K, do not include that part of the mineral resources converted to proven and probable mineral reserves or measured and indicated mineral resources, and have been estimated in conformance with definitions set out in Canada’s National Instrument 43-101. We have filed on SEDAR (www.sedar.com) Technical Reports on our mineral reserves and mineral resources (mineral resources stated in the Technical Reports include mineral reserves) for Bogoso/Prestea and Wassa as required in Canada’s National Instrument 43-101. We intend to file Technical Reports for Bogoso/Prestea and Wassa as of December 31, 2003 during the first quarter of 2004. See our “Glossary of Terms”.

The inferred mineral resources for our properties have been estimated at economic cut-off grades based on gold prices of $375 and $325 per ounce as of December 31, 2003 and December 31, 2002, respectively, and economic constraints that we believe are realistic.

(1) See Glossary of Terms for definitions of non-reserves — mineral resources and inferred mineral resources.

The estimation of the Bogoso/Prestea, Wassa, and Prestea Underground inferred mineral resources are based on information compiled and/or validated by Mr. S. Mitchell Wasel, Exploration Manager. Mr. Wasel is a qualified geologist who has 16 years of experience in gold and base metal exploration and is a member of the Australasian Institute of Mining and Metallurgy.

The primary qualified person responsible for the estimation of the inferred mineral resource for the Yaou, Dorlin and Paul Isnard property is Mr. Colin Jones, who is a professional geologist with 22 years of experience. Mr Jones is a Partner and Manager (Audits) of RSG Global Pty Ltd and a member of the Australian Institute of Mining and Metallurgy. The amount of the mineral resource at the Dorlin property that might have been removed by illegal mining is not known but could be material.

(2) Approximately 84% of the 2003 Bogoso/Prestea inferred mineral resources are refractory. The estimated cut-off grades utilized in inferred mineral resource calculations in 2003 ranged from 0.7 g/t to 1.8 g/t for non-refractory

material and from 0.9 g/t to 2.1 g/t for refractory material. Also included in the December 31, 2003 inferred mineral resource category are the Dunkwa properties mineral resources of 2.4 million tonnes of ore at an average grade of approximately 2.69 g/t, which were purchased as part of the Dunkwa properties acquisition in June 2003.

(3) All of the Wassa inferred mineral resources are non-refractory. The estimated cut-off grades utilized in mineral resource calculations in 2003 ranged from 0.5 g/t to 0.6 g/t.

(4) All of the Prestea Underground inferred mineral resources are refractory. Golden Star owns approximately a 59% beneficial interest in the property. The estimated cut-off grade utilized in mineral resource calculations in 2003 was 4.2 g/t.

(5) Yaou is located in French Guiana, South America, and Golden Star owns approximately an 86.5% beneficial interest in the property. The estimated cut-off grade utilized in mineral resource calculations in 2003 was 0.5 g/t. The property is undeveloped and has been on a care and maintenance basis in recent years.

(6) Dorlin is located in French Guiana, South America, and Golden Star owns approximately an 86.5% beneficial interest in the property. The estimated cut-off grade utilized in mineral resource calculations in 2003 was 0.5 g/t. The property is undeveloped and has been on a care and maintenance basis in recent years.

(7) Paul Isnard is located in French Guiana, South America, and Golden Star owns approximately a 73% beneficial interest in the property. The estimated cut-off grades utilized in mineral resource calculations in 2003 was 0.4 g/t. The property is undeveloped and has been on a care and maintenance basis in recent years.

EXPLORATION

We spent approximately $8.5 million in exploration activities during 2003 including $2.2 million at Wassa establishing mineral reserves in the existing pits and in areas outside the pits, $3.1 million at the Prestea Underground, including underground care and maintenance costs, $2.3 million on exploration projects outside the Wassa and Bogoso/Prestea areas and $0.9 million developing new mineral reserves in the Plant North area. Exploration spending during 2003 was less than expected due to a shortage of drill rigs in Ghana. Recent increases in exploration activity in Ghana by us and our competitors have adversely impacted drill rig availability and as a result some of our planned work was delayed, including drilling at the Prestea Underground which was delayed several months.

Most of our exploration efforts in 2003 were focused on Ghana, with Prestea Underground, Prestea, Wassa and the Akropong Trend properties receiving the most attention. Late in 2003 we began to explore the newly acquired Dunkwa properties north of Bogoso. During 2004 we plan to spend approximately $21 million on gold exploration. Approximately $6 million will be used to evaluate surface projects in and around Bogoso/Prestea including the Akropong Trend and Dunkwa properties. Approximately $6.6 million is planned for the continued exploration efforts at the Prestea Underground project, $2.5 million is scheduled for the Wassa area, $2.4 million is expected to be spent on the properties in Sierra Leone and Mali, both in West Africa, $1.7 million is expected to be used to identify and evaluate projects in South America, including some of Guyanor’s holdings, and $1.6 million is planned for our project generation program.

We entered, subject to definitive documentation and government approval, into a joint venture agreement in late 2003 to invest up to $6 million over the next four years in the Mano River project in Sierra Leone via an earn-in agreement with a junior exploration company which now holds a group of gold exploration properties in Sierra Leone. The initial $6 million, if fully funded (we can terminate the joint venture agreement after spending $1.0 million), would yield a 51% interest in the joint venture. Further provisions of the joint venture agreement provide the opportunity to acquire up to 85% of the joint venture by continued long term funding. Spending was nil in 2003.

In late 2003 we entered into a second joint venture agreement, subject to definitive documentation and government approval, agreeing to fund exploration work on the Mininko gold property in Mali. Funding of $2.6 million would

15

Table of Contents

earn a 51% interest in the joint venture. We can terminate the joint venture agreement after spending $0.4 million, of which $0.1 million was spent in 2003. The joint venture agreement provides that we can earn up to an 82.5% interest by continued funding of exploration and development.

We also provided $0.9 million of funding during 2003 to a junior exploration company working in South America. The Guyanor properties were maintained on a care and maintenance basis during 2003, but we expect to initiate new exploration efforts there in 2004 focusing on further evaluation of our existing properties and recently acquired properties.

We do not believe it to be cost effective at this point to add exploration staff or to establish additional exploration offices. As such, we expect to utilize funding of joint ventures for much of our exploration activities outside the Bogoso/Prestea area where our current exploration staff resides.

EMPLOYEE RELATIONS

As of December 31, 2003 Golden Star, including our majority owned subsidiaries and joint ventures, had approximately 1,000 employees and contract employees, a 9% decrease from the approximately 1,100 people employed at the end of 2002. The total includes ten employees and four part-time or contract employees at our principal office in Littleton, Colorado.

CUSTOMERS

All of our gold is sold to a single European bank in accordance with a long-term contract whereby cash payment for gold sold is received in our account two to three working days after each shipment with title passing at the point of shipment at the Accra International Airport. The global gold market is competitive with numerous banks and refineries willing to buy gold on short notice, therefore we believe that the loss of our current customer would not materially delay or disrupt revenues.

COMPETITION

We compete with major mining companies and other natural mineral resource companies in the acquisition, exploration, financing and development of new prospects. Many of these companies are larger and better capitalized than we are. There is significant competition for the limited number of gold acquisition and exploration opportunities. Our competitive position depends upon our ability to successfully and economically explore, acquire and develop new and existing mineral prospects. Factors that allow producers to remain competitive in the market over the long term include the quality and size of their orebodies, costs of operation, and the acquisition and retention of qualified employees. We also compete with other mining companies for skilled mining engineers, mine and processing plant operators and mechanics, geologists, geophysicists and other technical personnel. This could result in higher turnover and greater labor costs.

RISK FACTORS

You should consider carefully the following discussion of risks, in addition to the other information contained in, or incorporated by reference into, this report.

Financial Risks

Our business is substantially dependent on gold prices.

The price of our common shares, our financial results and our exploration, development and mining activities have previously been, and would in the future be, significantly adversely affected by fluctuations in the price of gold. The price of gold is volatile and is affected by numerous factors beyond our control such as the sale or purchase of gold by various central banks and financial institutions, inflation or deflation, fluctuation in the value of the US dollar and foreign currencies, global and regional demand, and the political and economic conditions of major gold-producing countries throughout the world. If gold prices were to decline significantly or for an extended period of time, we might be unable to continue our operations, develop our properties or fulfill our obligations under our agreements with our partners or under our permits and licenses. As a result, we could lose our interest in, or be forced to sell, some of our properties.

Furthermore, mineral reserve calculations and life-of-mine plans using significantly lower gold prices could result in reduced estimates of mineral reserves and non-reserve mineral resources and in material write-downs of our investment in mining properties and increased amortization, reclamation and closure charges.

We have recorded substantial losses in the past.

While we had earnings of $22.0 million and $ 4.9 million in 2003 and 2002, respectively, we reported net losses of $20.6 million in 2001, $14.9 million in 2000, and $24.4 million in 1999. Numerous factors, including declining gold prices, lower than expected ore grades or higher than expected operating costs, and impairment write-offs of mine property and/or exploration property costs, could cause us to become unprofitable in the future. Any future operating losses could make financing our operations and our business strategy, or raising additional capital, difficult or impossible and could materially and adversely affect our operating results and financial condition.

Our obligations could strain our financial position and impede our business strategy.

We have total debts and liabilities as of December 31, 2003 of $16.6 million, including $0.8 million payable to financial institutions, $8.0 million of current trade payables and accrued current liabilities and $7.7 million in environmental rehabilitation liabilities. We expect that our indebtedness and other liabilities will increase as a result of our corporate development activities. This indebtedness could have important consequences, including the following:

•

increasing our vulnerability to general adverse economic and industry conditions;

•

limiting our ability to obtain additional financing to fund future working capital, capital expenditures, operating and exploration costs and other general corporate requirements;

•

requiring us to dedicate a significant portion of our cash flow from operations to make debt service payments, which would reduce our ability to fund working capital, capital expenditures, operating and exploration costs and other general corporate requirements;

•

limiting our flexibility in planning for, or reacting to, changes in our business and the industry; and

•

placing us at a disadvantage when compared to our competitors that have less debt relative to their market capitalization.

Our estimates of mineral reserves and non-reserves could be inaccurate.

There are numerous uncertainties inherent in estimating proven and probable mineral reserves and measured, indicated and inferred mineral resources, including many factors beyond our control. The estimation of mineral reserves and non-reserves is a subjective process, and the accuracy of any such estimates are a function of the quantity and quality of available data and of the assumptions made and judgments used in engineering and

17

Table of Contents

geological interpretation, which could prove to be unreliable. There can be no assurance that these estimates will be accurate, that mineral reserves and non-reserves figures will be accurate, or that mineral reserves or non-reserves could be mined or processed profitably.

Fluctuation in gold prices, results of drilling, metallurgical testing and production and the evaluation of mine plans subsequent to the date of any estimate could require revision of the estimate. The volume and grade of mineral reserves mined and processed and recovery rates might not be the same as currently anticipated. Any material reductions in estimates of our mineral reserves and non-reserves, or of our ability to extract these mineral reserves and non-reserves, could have a material adverse effect on our results of operations and financial condition.

We currently have only one source of operational cash flows.

While we have recently received significant infusions of cash from sales of equity, our only internal source of funds is operational cash flows from Bogoso/Prestea. We expect to commence production at Wassa in early 2004, although there can be no assurance that our Wassa production goals will be achieved. The anticipated continuing exploration and development of our properties will require significant expenditures over the next several years. We expect that these expenditures will exceed free cash flows generated by Bogoso/Prestea during that period, and therefore we expect to use our excess cash and in the future to require additional outside capital. Lower gold prices during the five years prior to 2002 adversely affected our ability to obtain financing, and recurring lower gold prices could have similar effects in the future. We cannot assure you that in the future we will be able to obtain adequate financing on acceptable terms. If we are unable to obtain additional financing, we might need to delay or indefinitely postpone further exploration and development of our properties, and as a result, we could lose our interest in, or could be forced to sell, some of our properties.

Implementation of a hedging program might be unsuccessful and incur losses.

We continue to review whether or not, in light of the potential for gold prices to fall, it would be appropriate to establish a hedging program. To date, we have not decided to implement a hedging program, although we have purchased and expect to continue to purchase puts from time to time, which give us the right to sell gold in the future at a fixed price. The implementation of a hedging program might not, however, protect adequately against declines in the price of gold.

In addition, although a hedging program could protect us from a decline in the price of gold, it might also prevent us from benefiting fully from price increases. For example, as part of a hedging program, we could be obligated to sell gold at a price lower than the then-current market price. Finally, if unsuccessful, the costs of any hedging program could further deplete our financial resources.

We are subject to fluctuations in currency exchange rates, which could materially adversely affect our financial position.

Our revenues are in US dollars, and we maintain most of our working capital in US dollars or US dollar-denominated securities. We convert funds to foreign currencies as payment obligations become due. A significant portion of the operating costs at Bogoso/Prestea is based on the Ghanaian currency, the Cedi. We are required to convert into Cedis only 20% of the foreign exchange proceeds that we receive from selling gold, but the Government of Ghana could require us to convert a higher percentage of such sales proceeds into Cedis in the future. In addition, we currently have future obligations that are payable in Euros, and receivables collectible in Euros. We obtain construction and other services and materials and supplies from providers in South Africa and other countries, and the costs of those services could increase due to changes in the value of the South African Rand or other currencies. Accordingly, we are subject to fluctuations in the rates of currency exchange between the US dollar and these currencies, and such fluctuations could materially affect our financial position and results of operations. Consequently, construction, development and other costs might be higher than we anticipate. We currently do not hedge against currency exchange risks, although we might do so from time to time in the future. There can be no assurance that implementation of a currency hedging program would adequately protect us from the effects of fluctuation in currency exchange rates.

There could be no opportunity to evaluate the merits or risks of any future acquisition undertaken by us.

18

Table of Contents

As a key element of our growth strategy, we have stepped up the active pursuit of acquisitions of producing, development and advanced stage exploration properties and companies. We are actively investigating potential acquisition and merger candidates. Risks related to acquiring and operating acquired properties and companies could have a material adverse effect on our results of operations and financial condition. In addition, to acquire properties and companies, we would use our available cash, incur debt, issue our common shares or other securities, or a combination of any one or more of these. This could limit our flexibility to raise capital, to operate, explore and develop our properties and to make additional acquisitions, and could further dilute and decrease the trading price of our common shares. Acquisition transactions in our business are often initiated and completed over a particularly short period of time. There could be no opportunity for our shareholders to evaluate the merits or risks of any future acquisition undertaken by us except as required by applicable laws and regulations.

Risks inherent in acquisitions that we might undertake could adversely affect our growth and financial condition.

We are actively pursuing the acquisition of producing, development and advanced stage exploration properties and companies, and have recently completed the acquisition of exploration and development properties in Ghana. From time to time, we might acquire securities of or other interests in companies with which we could enter into acquisitions or other transactions. Acquisition transactions involve inherent risks, including:

•

accurately assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of acquisition candidates;

•

ability to achieve identified and anticipated operating and financial synergies;

•

unanticipated costs;

•

diversion of management attention from existing business;

•

potential loss of our key employees or the key employees of any business we acquire;

•

unanticipated changes in business, industry or general economic conditions that affect the assumptions underlying the acquisition; and

•

decline in the value of acquired properties, companies or securities.

Any one or more of these factors or other risks could cause us not to realize the benefits anticipated to result from the acquisition of properties or companies, and could have a material adverse effect on our ability to grow and on our financial condition.

We are subject to litigation risks.

All industries, including the mining industry, are subject to legal claims, with and without merit. We are involved in various routine legal proceedings, which include labor matters such as unfair termination claims, supplier matters and property issues incidental to our business. We believe it is unlikely that the final outcome of these legal proceedings will have a material adverse effect on our financial position or results of operation. However, defense and settlement costs can be substantial, even with respect to claims that have no merit. Due to the inherent uncertainty of the litigation process, there can be no assurance that the resolution of any particular legal proceeding will not have a material effect on our financial position or results of operations.

Operational Risks

The technology, capital costs and cost of production of refractory mineral reserves and non-reserves at Bogoso/Prestea remain subject to a number of uncertainties, including funding uncertainties.

Based upon the completion of our Bogoso sulfide project feasibility study in 2001 and its subsequent review by a qualified person under Canada’s National Instrument 43-101, the refractory material at Bogoso/Prestea has been included in our proven and probable mineral reserves. While the sulfide project feasibility study indicated that refractory mineral reserves can be profitably mined and processed at gold prices at or above $275 per ounce, the capital cost to upgrade the Bogoso processing plant with a bio-oxidation or BIOX circuit to process refractory ore, together with related mining equipment, and facilities, is significant. The capital cost of the sulfide project together with our other Bogoso/Prestea expansion plans including capitalized exploration, mine development, and expanding the mining fleet is expected to be approximately $70 million expected to be spent in 2004 and 2005. We cannot assure you that we will have access to capital, whether from internal or external sources, in the required amounts or on acceptable terms. While the processing technology envisioned in the feasibility study has been successfully utilized at other mines, we cannot

19

Table of Contents

assure you, in spite of our testing, engineering and analysis, that the technology will perform successfully at commercial production levels on the Bogoso/Prestea refractory sulfide ores. Therefore, we cannot assure you that our production estimates can be achieved.

Completion of development of Wassa and the projected expansion of Bogoso/Prestea is subject to a number of uncertainties.

We have completed a feasibility study regarding the development of and commencement of production at Wassa in Ghana using conventional CIL processing techniques and have commenced development of the Wassa mine. We cannot assure you that production will commence when we currently anticipate. We have not yet completed technical studies for the projected $70 million expansion of Bogoso/Prestea. The management of mine development projects and start-up of new operations are complex. We do not have a history of managing simultaneously two significant development projects and an ongoing operation. We cannot assure you that these development projects will be completed at the cost and on the schedule predicted, or that gold grades and recoveries, production rates or costs anticipated will be achieved. Any development of Wassa and expansion of Bogoso/Prestea are subject to all of the risks described in this Form 10-K, including “Risk Factors — Operational Risks — The development and operation of our mining projects involve numerous uncertainties.”

Declining gold prices could reduce our estimates of mineral reserves and non-reserves and could result in delays in development until we can make new estimates and determine new potential economic development options under the lower gold price assumptions.

In addition to adversely affecting our mineral reserve estimates and our financial condition, declining gold prices could impact operations by requiring a reassessment of the feasibility of all or a portion of a particular project. A reassessment might be the result of a management decision or could be required under financing arrangements related to the project. Even if the project is ultimately determined to be economically viable, the need to conduct a reassessment could cause substantial delays or might interrupt operations until the reassessment can be completed.

We are subject to a number of operational hazards that can delay production or result in liability to us.

Our activities are subject to a number of risks and hazards including:

•

environmental hazards;

•

discharge of pollutants or hazardous chemicals;

•

industrial accidents;

•

labor disputes;

•

supply and shipping problems and delays;

•

unusual or unexpected geological or operating conditions;

•

slope failures;

•

cave-ins of underground workings;

•

failure of pit walls or dams;

•

fire;

•

changes in the regulatory environment; and

•

natural phenomena such as inclement weather conditions, floods and earthquakes.

These or other occurrences could result in damage to, or destruction of, mineral properties or production facilities, personal injury or death, environmental damage, delays in mining, delayed production, monetary losses and possible legal liability. We could incur liabilities as a result of pollution and other casualties. Satisfying such liabilities could be very costly and could have a material adverse effect on our financial position and results of operations.

Our mining operations are subject to numerous environmental laws, regulations and permitting requirements that can delay production and adversely affect operating and development costs.

We cannot assure you that compliance with existing regulations governing the discharge of materials into the environment, or otherwise relating to environmental protection, in the jurisdictions where we have projects will not have a material adverse effect on our exploration activities, results of operations or competitive position. New or expanded regulations, if adopted, could affect the exploration or development of our projects or otherwise have a material adverse effect on our operations.

A significant portion of our recently acquired Dunkwa property and portions of our Wassa development property as well as some of our exploration properties in Ghana are located within forest reserve areas. Although Dunkwa and

20

Table of Contents

Wassa have been identified by the Government of Ghana as eligible for mining permits subject to normal procedures and a site inspection, there can be no assurance that permits for projects in forest reserve areas will be issued in a timely fashion, or at all, or that such permits will not contain special requirements with which it is burdensome or expensive to comply.

Our planned development of Wassa, relocation of the processing plant to Bondaye near Prestea, conversion of the existing Bogoso/Prestea processing plant to process refractory sulfides and other activities will require mining and other permits from the Government of Ghana. There can be no assurance that these permits will be issued on a timely basis or at all, or that permits issued will not be subject to requirements or conditions with which it is burdensome or expensive to comply. This could adversely affect our projected production commencement dates, production amounts and costs.

As a result of the foregoing risks, project expenditures, production quantities and rates and cash operating costs, among other things, could be materially and adversely affected and could differ materially from anticipated expenditures, production quantities and rates, and costs. In addition, estimated production dates could be delayed materially. Any such events could materially and adversely affect our business, financial condition, results of operations and cash flows.

The development and operation of our mining projects involve numerous uncertainties.

Mine development projects, including our ongoing development at Wassa and anticipated expansion at Bogoso/Prestea, typically require a number of years and significant expenditures during the development phase before production is possible.

Development projects are subject to the completion of successful feasibility studies and environmental assessments, issuance of necessary governmental permits and receipt of adequate financing. The economic feasibility of development projects is based on many factors such as:

•

estimation of mineral reserves and mineral resources;

•

anticipated metallurgical recovery rates;

•

environmental considerations and permitting;

•

future gold prices; and

•

anticipated capital and operating costs of such projects.

Our mine development projects could have limited relevant operating history upon which to base estimates of future operating costs and capital requirements. Estimates of proven and probable mineral reserves and operating costs determined in feasibility studies are based on geologic and engineering analyses and might not prove to be accurate.

Any of the following events, among others, could affect the profitability or economic feasibility of a project:

•

unanticipated changes in grade and tonnage of ore to be mined and processed;

•

unanticipated adverse geotechnical conditions;

•

incorrect data on which engineering assumptions are made;

•

costs of constructing and operating a mine in a specific environment;

•

availability and cost of processing and refining facilities;

•

availability of economic sources of power;

•

adequacy of water supply;

•

adequate access to the site including competing land uses (such as agriculture and illegal mining);

•

unanticipated transportation costs;

•

government regulations (including regulations relating to prices, royalties, duties, taxes, permitting, restrictions on production, quotas on exportation of minerals, as well as the costs of protection of the environment and agricultural lands);

•

fluctuations in gold prices; and

•

accidents, labor actions and force majeure events.

Adverse effects on the operations or further development of a project could also adversely affect our business, financial condition, results of operations and cash flow. Because of these uncertainties, and others identified in “Risk

21

Table of Contents

Factors”, there can be no assurance that our production estimates at Bogoso/Prestea and Wassa can or will be achieved.

We need to continually obtain additional mineral reserves for gold production.

Because mines have limited lives based on proven and probable mineral reserves, we must continually replace and expand our mineral reserves as our mines produce gold. At current average production rates, we estimate that Bogoso/Prestea has over ten years of mine life, but our estimates might not be correct and the mine life would be shortened if we expand production. Our ability to maintain or increase our annual production of gold will be dependent in significant part on our ability to bring new mines into production and to expand or extend the life of existing mines.

Gold exploration is highly speculative, involves substantial expenditures, and is frequently non-productive.

Gold exploration, including the exploration of the Prestea Underground, involves a high degree of risk and exploration projects are frequently unsuccessful. Few prospects that are explored end up being ultimately developed into producing mines. To the extent that we continue to be involved in gold exploration, the long-term success of our operations will be related to the cost and success of our exploration programs. We cannot assure you that our gold exploration efforts will be successful. The success of gold exploration is determined in part on the following factors:

•

the identification of potential gold mineralization based on superficial analysis;

•

the quality of our management and our geological and technical expertise; and

•

the capital available for exploration and development.

Substantial expenditures are required to determine if a project has economically mineable mineralization. It could take several years to establish proven and probable mineral reserves and to develop and construct mining and processing facilities. As a result of these uncertainties, we cannot assure you that current and future exploration programs will result in the discovery of mineral reserves, the expansion of our existing mineral reserves and the development of mines.

We face competition from other mining companies in connection with the acquisition of properties.

We face strong competition from other mining companies in connection with the acquisition of properties producing, or capable of producing, precious metals. Many of these companies have greater financial resources, operational experience and technical capabilities. As a result of this competition, we might be unable to maintain or acquire attractive mining properties on terms we consider acceptable or at all. Consequently, our revenues, operations and financial condition could be materially adversely affected.

Title to our mineral properties could be challenged.

Our policy is to seek to confirm the validity of our rights to title to, or contract rights with respect to, each mineral property in which we have a material interest. However, we cannot guarantee that title to our properties will not be challenged. Title insurance generally is not available, and our ability to ensure that we have obtained secure claim to individual mineral properties or mining concessions could be severely constrained. We might not have conducted surveys of all of the properties in which we hold direct or indirect interests and, therefore, their precise area and location could be in doubt. Accordingly, our mineral properties could be subject to prior unregistered agreements, transfers or claims, and title could be affected by, among other things, undetected defects. In addition, we might be unable to operate our properties as permitted or to enforce our rights with respect to our properties.

We depend on the services of key executives.

We are dependent on the services of key executives including our President and Chief Executive Officer and a small number of highly skilled and experienced executives and personnel. Due to the relatively small size of our company, the loss of these persons or our inability to attract and retain additional highly skilled employees could adversely affect the exploration and development of our properties, which could have a material adverse effect on our business and future operations.

22

Table of Contents

The period of weak gold prices prior to 2002 resulted in the depletion in the number of trained and experienced professionals and managers in our industry. Higher gold prices have resulted in an increased demand for these people, and it could therefore be more difficult to attract or retain such experienced professionals and managers without significantly increasing the cost to Golden Star.

Our insurance coverage could be insufficient.

Our business is subject to a number of risks and hazards generally, including:

•

adverse environmental conditions;

•

industrial accidents;

•

labor disputes;

•

unusual or unexpected geological conditions;

•

ground or slope failures;

•

cave-ins;

•

changes in the regulatory environment; and

•

natural phenomena such as inclement weather conditions, floods and earthquakes.

Such occurrences could result in:

•

damage to mineral properties or production facilities;

•

personal injury or death;

•

environmental damage to our properties or the properties of others;

•

delays in mining;

•

monetary losses; and

•

possible legal liability.

Although we maintain insurance in amounts that we believe to be reasonable, our insurance might not cover all the potential risks associated with our business. We might also be unable to maintain insurance to cover these risks at economically feasible premiums. Insurance coverage might not continue to be available or might not be adequate to cover any resulting liability. Moreover, insurance against risks such as environmental pollution or other hazards as a result of exploration and production is not generally available to us or to other companies in the mining industry on acceptable terms. We might also become subject to liability for pollution or other hazards which we cannot insure against or which we might elect not to insure against because of premium costs or other reasons. Losses from these events might cause us to incur significant costs that could have a material adverse effect upon our financial performance and results of operations.

Governmental and Regulatory Risks

As a holding company, limitations on the ability of our operating subsidiaries to make distributions to us could adversely affect the funding of our operations.

We are a holding company that conducts operations through foreign (principally African) subsidiaries and joint ventures, and substantially all of our assets consist of equity in these entities. Accordingly, any limitation on the transfer of cash or other assets between the parent corporation and these entities, or among these entities, could restrict our ability to fund our operations efficiently. Any such limitations, or the perception that such limitations might exist now or in the future, could have an adverse impact on our valuation and stock price.

We are subject to changes in the regulatory environment where we operate.

Our mining operations and exploration activities are subject to extensive regulation governing various matters, including:

23

Table of Contents

Compliance with these regulations increases the costs of the following:

We believe that we are in substantial compliance with current laws and regulations in Ghana and elsewhere. However, these laws and regulations are subject to frequent change and reinterpretation. Due to the substantial increase in mining development during 2003 in Ghana, the Government of Ghana has been reviewing the adequacy of reclamation bonds and guarantees throughout the country and in some cases has requested higher levels of bonding than previously had been required. There can be no assurance that our bonds would not be increased. Amendments to current laws and regulations governing operations and activities of mining companies or more stringent implementation or interpretation of these laws and regulations could have a material adverse impact on us, cause a reduction in levels of production and delay or prevent the development or expansion of our properties in Ghana.

Government regulations limit the proceeds from gold sales that could be withdrawn from Ghana. Changes in regulations that increase these restrictions could have a material adverse impact on us, as Bogoso/Prestea is currently our only source of internally generated operating cash flows.

The Government of Ghana has the right to participate in the ownership and control of certain subsidiaries.

The Government of Ghana currently has a 10% carried interest in our subsidiaries that own our Bogoso/Prestea mine, Wassa development property and Prestea Underground property. The Government of Ghana also has: (a) the right to acquire up to an additional 20% equity interest in each of these subsidiaries for a price to be determined by agreement or arbitration; (b) the right to acquire a special share or golden share in such subsidiaries at any time for no consideration or such consideration as the Government of Ghana and such subsidiaries might agree; and (c) a pre-emptive right to purchase all gold and other minerals produced by such subsidiaries. We cannot assure you that the Government of Ghana would not seek to exercise one or more of these rights, which could reduce our equity interest. A reduction in our equity interest could reduce our income or cash flows from Bogoso/Prestea and/or reduce our anticipated income or cash flows from Wassa, reducing amounts available to us for reinvestment and adversely affecting our ability to take certain actions.

We are subject to risks relating to exploration, development and operations in foreign countries.

Certain laws, regulations and statutory provisions in certain countries in which we have mineral rights could, as they are currently written, have a material negative impact on our ability to develop or operate a commercial mine. For countries where we have exploration or development stage projects, we intend to negotiate mineral agreements with the governments of these countries and seek variances or otherwise be exempted from the provisions of these laws, regulations and/or statutory provisions. We cannot assure you, however, that we will be successful in obtaining mineral agreements or variances or exemptions on commercially acceptable terms.

Our assets and operations are affected by various political and economic uncertainties, including:

•

the risks of war, civil unrest, coups or other violent or unexpected changes in government;

•

political instability and violence;

•

expropriation and nationalization;

•

renegotiation or nullification of existing concessions, licenses, permits, and contracts;

•

illegal mining;

•

changes in taxation policies;

•

restrictions on foreign exchange and repatriation; and

•

changing political conditions, currency controls, and governmental regulations that favor or require the awarding of contracts to local contractors or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction.

Illegal mining occurs on our properties, is difficult to control, can disrupt our business and can expose us to liability.

Artisanal miners illegally work on our properties from time to time, despite the fact that we have hired security personnel to protect our properties. The presence of illegal miners could lead to project delays and disputes regarding the development or operation of commercial gold deposits. The work performed by the illegal miners could cause environmental damage or other damage to our properties, or personal injury or death for which we could potentially be held responsible. Extensive illegal mining could result in surface depletion of mineral deposits, potentially making the future mining of such deposits uneconomic.

Our activities are subject to complex laws, regulations and accounting standards that can adversely affect operating and development costs, the timing of operations, the ability to operate and financial results.

Our business, mining operations and exploration and development activities are subject to extensive Canadian, US, Ghanaian and other foreign, federal, state, provincial, territorial and local laws and regulations governing exploration, development, production, exports, taxes, labor standards, waste disposal, protection of the environment, reclamation, historic and cultural resource preservation, mine safety and occupational health, toxic substances, reporting and other matters, as well as accounting standards. Compliance with these laws, regulations and standards or the imposition of new such requirements could adversely affect operating and development costs, the timing of operations, the ability to operate and financial results.

Market Risks

The market price of our common shares could experience volatility and could decline significantly.

Our common shares are listed on the American Stock Exchange and the Toronto Stock Exchange. Securities of small-cap companies have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved. These factors include macroeconomic developments in North America and globally and market perceptions of the attractiveness of particular industries. Our share price is also likely to be significantly affected by short-term changes in gold prices or in our financial condition or results of operations as reflected in our quarterly earnings reports. Other factors unrelated to our performance that could have an effect on the price of our common shares include the following:

•

the extent of analytical coverage available to investors concerning our business could be limited if investment banks with research capabilities do not continue to follow our securities;

•

the trading volume and general market interest in our securities could affect an investor’s ability to trade significant numbers of common shares;

•

the relatively small size of the public float will limit the ability of some institutions to invest in our securities; and

•

a substantial decline in our stock price that persists for a significant period of time could cause our securities to be delisted from the American Stock Exchange and the Toronto Stock Exchange, further reducing market liquidity.

As a result of any of these factors, the market price of our common shares at any given point in time might not accurately reflect our long-term value. Securities class action litigation often has been brought against companies

25

following periods of volatility in the market price of their securities. We could in the future be the target of similar litigation. Securities litigation could result in substantial costs and damages and divert management’s attention and resources.

You could have difficulty or be unable to enforce certain civil liabilities on us, certain of our directors and our experts.

We are a Canadian corporation. Substantially all of our assets are located outside of Canada and the US, and our head office is located in the US. Additionally, a number of our directors and the experts named in this Form 10-K are residents of Canada. Although we have appointed Koffman Kalef, Suite 1900, 885 West Georgia Street, Vancouver, British Columbia and Field LLP, 1900, 350 - 7th Avenue S.W., Calgary, Alberta as our agents for service of process in the Provinces of British Columbia and Alberta respectively, it might not be possible for investors to collect judgments obtained in Canadian courts predicated on the civil liability provisions of securities legislation. It could also be difficult for you to effect service of process in connection with any action brought in the US upon such directors and experts. Execution by US courts of any judgment obtained against us or, any of the directors, executive officers or experts named in this Form 10-K in US courts would be limited to the assets of Golden Star Resources Ltd. or the assets of such persons or corporations, as the case might be, in the US. The enforceability in Canada of US judgments or liabilities in original actions in Canadian courts predicated solely upon the civil liability provisions of the federal securities laws of the US is doubtful.

There may be certain tax risks associated with investments in our company.

Potential investors that are US taxpayers should consider that we could be considered to be a “passive foreign investment company” (“PFIC”) for federal income tax purposes. Although we believe that we currently are not a PFIC and do not expect to become a PFIC in the near future, the tests for determining PFIC status are dependent upon a number of factors, some of which are beyond our control, and we can not assure you that we would not become a PFIC in the future. If we were deemed to be a PFIC, then a US taxpayer who disposes or is deemed to dispose of our shares at a gain, or who received a so-called “excess distribution” on the shares, generally would be required to treat such gain or excess distribution as ordinary income and pay an interest charge on a portion of the gain or distribution unless the taxpayer makes a timely qualified electing fund election (a “QEF” election). A US taxpayer who makes a QEF election generally must report on a current basis his or her share of any of our ordinary earnings and net capital gain for any taxable year in which we are a PFIC, whether or not we distribute those earnings. Special estate tax rules could be applicable to our shares if we are classified as a PFIC for income tax purposes.

We do not anticipate paying dividends in the foreseeable future.

We anticipate that we will retain all future earnings and other cash resources for the future operation and development of our business. We do not intend to declare or pay any cash dividends in the foreseeable future. Payment of any future dividends will be at the discretion of our board of directors after taking into account many factors, including our operating results, financial condition, and current and anticipated cash needs.

Future sales of our common shares by our existing shareholders could decrease the trading price of the common shares.

Sales of a large number of our common shares in the public markets, or the potential for such sales, could decrease the trading price of our common shares and could impair our ability to raise capital through future sales of our common shares. We completed sales of units, comprised of common shares and warrants, in January, July and December 2002 and February 2003 and sales of common shares in August, October, and December 2003, all but the December 2003 offering at prices significantly less than the current market price of our common shares. Accordingly, a significant number of our shareholders have an investment profit in our securities that they could seek to liquidate. Substantially all of our common shares not held by affiliates can be resold without material restriction in the US and Canada.

The existence of outstanding rights to purchase common shares could impair our ability to raise capital.

As of December 31, 2003 approximately 22.6 million common shares are issuable on exercise of warrants, options or other rights to purchase common shares at prices ranging from Cdn$1.02 to Cdn$9.07. During the life of the warrants, options and other rights, the holders are given an opportunity to profit from a rise in the market price of our common shares with a resulting dilution in the interest of the other shareholders. Our ability to obtain additional financing during the period such rights are outstanding could be adversely affected, and the existence of the rights could have an adverse effect on the price of our common shares. The holders of the warrants, options and other rights can be expected to exercise them at a time when we would, in all likelihood, be able to obtain any needed capital by new offering of securities on terms more favorable than those provided by the outstanding rights.

MINING IN GHANA

Ghanaian Ownership and Special Rights

Ghana is situated on the West Coast of Africa, approximately 600 kilometers north of the equator on the Gulf of Guinea. Accra, the capital city of Ghana, is located on the Prime Meridian. After a period as a British colony, Ghana achieved independence in 1957 and it is now a republic with a democratically elected government. Ghana has a population of approximately 20 million people. English is the official and commercial language. The total land area of the country is approximately 238,000 square kilometers and the topography is relatively flat. Ghana has a tropical climate with two rainy seasons and two dry seasons, each year.

Rights to explore and develop a mine are administered through the Minerals Commission, a governmental organization designed to promote and control the development of Ghana’s mineral wealth. A company or individual can apply to the Minerals Commission for a renewable exploration concession granting exclusive rights to explore for a particular mineral in a selected area for a period of two years. When exploration has successfully delineated a mineable mineral reserve, an application is made to the Minerals Commission for conversion to a mining lease, granting a company the right to produce a specific product from the concession area for a period of normally 20 to 30 years. Production must begin within two years of the date of granting a mining lease.

The Government of Ghana has a 10% carried interest in BGL and WGL, and is entitled to acquire up to an additional 20% interest in each of BGL and WGL. The carried interest entitles the Government of Ghana to a pro-rata share of future dividends (none have been declared to date), if any, from BGL and WGL once all capital is repaid, and the Government of Ghana has no obligation to contribute development or operating expenses. BGL and WGL owe $61.1 million and $50.3 million, respectively, to Golden Star as of December 31, 2003 for past advances and debts and such amounts would be repaid to us before payment of any dividends. If the Government of Ghana wishes to exercise its right to acquire an additional 20%, it must first give reasonable notice, and pay a mutually agreed price. If there is no agreement, the purchase price would be the fair market value of such interest at such time as determined by arbitration conducted by the International Centre for the Settlement of Investment Disputes. The Government of Ghana could also acquire further interests in BGL and/or WGL on terms mutually acceptable to the Government and BGL or WGL. To date the Government has indicated no intent to obtain additional ownership in any of our properties.

The Government of Ghana is entitled to acquire a special or golden share in BGL or WGL or any mining company at any time for no consideration or such consideration as the Government of Ghana and BGL or WGL might agree. The special share would constitute a separate class of shares with such rights as the Government of Ghana and BGL or WGL might agree. In the absence of such agreement, the special share would have the following rights:

•

the special share would carry no voting rights, but the holder would be entitled to receive notice of and attend and speak at any general meeting of the members or any separate meeting of the holders of any class of shares;

•

the special share could only be issued to, held by, or transferred to the Government or a person acting on behalf of the Government;

28

Table of Contents

•

the written consent of the holder of the special share would be required for all amendments to the organizational documents of the company, the voluntary winding-up or liquidation of the company or the disposal of any mining lease or the whole or any material part of the assets of the company; and

•

the holder of the special share would be entitled to the payment of a nominal sum of 1,000 Ghanaian Cedis in a winding-up or liquidation of the company in priority to any payment to other members and could require the company to redeem the special share at any time for a nominal sum of 1,000 Cedis.

BGL and WGL have not issued nor to date been requested to issue any such special share to the Government of Ghana.

The Government of Ghana has a pre-emptive right to purchase all gold and other minerals produced by BGL and WGL. The purchase price would be such price as the Government of Ghana and BGL and WGL might agree on, or the price established by any gold hedging arrangement between BGL or WGL and any third party approved by the Government, or the publicly quoted market price prevailing for the minerals or products as delivered at the mine or plant where the right of preemption was exercised. The Government of Ghana has agreed to take no preemptive action pursuant to its right to purchase such gold or other minerals so long as BGL and WGL sell gold in accordance with certain procedures for selling gold approved by the Bank of Ghana.

Ghanaian Royalty Requirements

Under the laws of Ghana, a holder of a mining lease is required to pay quarterly a royalty of not less than 3% per annum and not more than 12% per annum of the total revenues earned from the lease area. The Government of Ghana determines the royalty percentage each year based on the ratio that the operating margin bears to the value of gold produced from a mining lease in that year. Based on the Mineral Royalty Regulation of 1987, the royalty is 3% when the operating ratio is 30% or less, the royalty increases 0.225% for each 1% increase in operating ratio until the royalty reaches a maximum of 12% at an operating ratio of 70%. In 2003, 2002 and 2001 the royalty rate for BGL was 3% of revenues, and the amounts paid were $1.9 million, $1.2 million and $0.7 million, respectively. The royalty payments from Golden Star have not exceeded 3% per annum in any year.

Ghanaian Environmental Regulations

BGL and WGL are in substantial compliance with the environmental requirements imposed by Ghanaian laws and guidelines and applicable guidelines and standards published by the World Bank. BGL completed significant work during 1999 to identify the outstanding reclamation liabilities for Bogoso/Prestea and to prepare a rehabilitation work plan. Significant work has been performed during 2001, 2002 and 2003 to advance this plan and to reduce the outstanding reclamation liability. Expenditures for ongoing rehabilitation work, including the capping of sulfide material, backfilling of worked out pits, and the contouring and re-vegetation of waste dumps, were approximately $0.8 million, $0.5 million, and $0.2 million for 2003, 2002, and 2001, respectively. As at December 31, 2003 BGL had $3.3 million of restricted cash set aside for environmental reclamation of the Bogoso Mine.

A reclamation liability of $2.3 million was recognized upon the acquisition of the Wassa property in September 2002, this amount representing the discounted estimated cost of reclamation as of the date of the acquisition.

Community Development Programs

In mid-2001 we initiated an “Alternative Livelihood and Sustainable Development Program” in the Bogoso/Prestea area. In 2004 we plan to expand the program to Wassa. The goals of the Program are to assist the communities in the vicinity of our mining operations to create alternative employment opportunities, promote growth of sustainable economic development and to reduce the community’s dependence on mining.

Given the importance of agriculture in the local economy, much of our efforts have been focused on agricultural opportunities. A demonstration farm has been established at one of the backfilled pits at Prestea where we now have a fish farm, a mulberry plantation and a silk production and processing facility. We plan to add demonstration plots of citrus crops and ginger in 2004. Studied have shown that Chinese silk production has fallen in recent years, providing an opportunity for new supply centers, and the climate of western Ghana appears to be well suited to sericulture.

29

Table of Contents

The farm facility is used for training and assistance to the 150 local farmers who have signed up to participate in the Program. In addition, the farm is providing participants with seed stock and fish and silk worms for use on their own farms.

Working with local Ghanaian government agencies, we have encouraged formation of agricultural cooperatives, the first of which has recently obtained a plot of ground in the Prestea area to initiate a silk operation. We have also made contact with various non-governmental developmental groups in hopes of facilitating availability of micro-project financing for the Bogoso/Prestea communities.

During 2004 we are planning to provide two new oil-palm/palm kernel processing facilities in the local area to more efficiently process the palm oil production already existing in the area.

In addition to the alternative livelihood projects, we are involved in the ongoing funding of several community assistance projects. We have provided funding and assistance for school improvements and equipment, libraries, a day care center, community centers, potable water systems, sports facilities and toilet facilities.

OPERATING PROPERTIES

The Bogoso/Prestea Operation

Overview of the Bogoso/Prestea Operation

Bogoso/Prestea consists of a gold mining/processing operation located along the Ashanti Trend in western Ghana, approximately 35 kilometers northwest of the town of Tarkwa from which it can be reached by paved roads. The mining areas at Prestea are linked to the Bogoso processing plant by paved and gravel haul-roads located on our properties. Equipment and facilities at Bogoso/Prestea include several open pit mines, a nominal 6,000 tonne per day CIL gold processing plant and a fleet of haul trucks, loaders and mining support equipment. In addition, there are numerous ancillary support facilities such as power and water supply equipment, haul roads, housing for management and technical staff, a medical clinic, tailings storage facility, waste dumps, warehouse, maintenance shops, offices and administrative facilities. The Bogoso/Prestea properties cover 224 square kilometers and mining rights are granted through several mining leases, which expire in or after August 2017.

Commercial mining at Bogoso dates back to the early years of the 20th century. During its 20-year period of operations from 1935 to 1955, production totaled over 900,000 ounces of gold at an average recovered grade of 3.73 g/t. Underground mining has been conducted at Prestea for more than 130 years. From 1873 to 1965, the current Prestea property was comprised of a number of different licenses operated by independent mining companies, which, in 1965, were amalgamated by the Government of Ghana into Prestea Goldfields Limited, under the aegis of the State Gold Mining Corporation.

BGL started surface mining operations on the Prestea concession in September 2001, with the first ore being processed at the Bogoso processing plant in October 2001. Total gold production from the Prestea area since recorded mining commenced in the 1870s is reported by the Ghana Chamber of Mines to be in excess of nine million ounces, making it the second largest historical gold producing area in Ghana, after the Obuasi mine.

The Bogoso property was acquired for a total cost of $18.9 million in a series of transactions beginning in 1999 with the final contingent payments being made in February 2003. In 2001, we acquired a 90% interest in the adjoining Prestea property for total consideration of approximately $8.0 million from Barnato Exploration Limited (“Barnex”) and Prestea Gold Resources Limited. Barnex retained a royalty interest in Prestea, which varied, according to a gold price formula, from a minimum of $6.00 per ounce at gold prices less than $260 per ounce to a maximum of $16.80 per ounce at gold prices at or above $340 per ounce. We bought back all of Barnex royalty rights for approximately $12.0 million in common shares in November 2003.

Bogoso/Prestea Expansion Project

The known mineral reserves at Bogoso/Prestea can be grouped into three general categories based on the metallurgy of the ore. They are referred to as: (a) oxide ore which is non-refractory and has been successfully processed in the existing Bogoso CIL and gravity circuits; (b) non-refractory transition and sulfide ores which we expect to

30

Table of Contents

successfully process at the Bogoso processing plant following the reactivation of the processing plant’s flotation circuit in early 2004; and (c) refractory transition and sulfide ores which would require some form of oxidation process prior to gold recovery. The oxide ores are found at surface, down to the general level of the water table, while sulfide ores are located at depth. Between these two distinct ore types lies the transition ore, of varying thickness, a zone of partially oxidized ore. Our Bogoso/Prestea reserves at the end of 2003 are comprised of approximately 13% oxide ore, 15% transition ores, and 72% sulfide ores on a gold content basis.

The existing Bogoso processing plant is configured to process primarily oxide ores. In recent years additions to the processing plant’s equipment made it possible to treat certain transition ores but not all of the transition ores known to exist at Bogoso/Prestea. Gold recovery from oxide ores is typically around 80% to 85% but when processing transition ores the recovery rate drops substantially below this. In 2001 when processing large tonnages of transition ores from the old Bogoso pits, the gold recovery rate dropped below 50%.

To facilitate efficient processing of the sulfide and transition ores and to expand the productive capacity of Bogoso/Prestea, we plan to make major modification to the existing Bogoso processing plant during 2004 and 2005 and at the same time add a second processing plant on the Prestea property, which will be designed to process oxide ores and other non-refractory ores.

In July 2003 we purchased a used 4,500 tonne per day conventional CIL processing plant, associated stores inventory, and a six-megawatt powerhouse from an inactive mine site in Ghana. This facility was dismantled in the third and fourth quarters of the year and will be moved to Prestea in early 2004. During 2004 we plan to reassemble this processing plant at a site approximately 5 kilometers south of the town of Prestea. With the appropriate modifications it should be able to process oxide ores and some of the transition ores found at Bogoso/Prestea. This new processing plant is now referred to as the Bondaye processing plant. We expect the Bondaye processing plant to be operational in the fourth quarter of 2004 if the required approvals and permits are obtained as expected.

Also during 2004 and into mid 2005, we plan to modify the existing Bogoso processing plant, via the addition of a bio-oxidation (“BIOX”) circuit, to process sulfide ore. The modifications would be done in a manner that will allow the Bogoso processing plant to continue processing oxide and transition ores during 2004 until the BIOX modifications are completed. We expect the Bogoso processing plant upgrades to be competed in 2005 and at that point begin to process only refractory transition and sulfide ores. Once the Bondaye processing plant construction and the Bogoso processing plant upgrades are completed, we anticipate being able to process all of the known ore types existing at Bogoso/Prestea and in the surrounding area.

We currently estimate the cost to move, reassemble and modify the Bondaye processing plant, to add the BIOX upgrade to the existing Bogoso processing plant, and to expand the mining fleet at Bogoso/Prestea as required to feed the expanded total complex, total about $70 million, not including the $4.3 million initial purchase cost of the Bondaye processing plant.

The BIOX process is designed to treat refractory gold ores prior to cyanidization by utilizing naturally occurring bacteria capable of oxidizing gold-bearing sulfide concentrates under controlled conditions. Prior to the BIOX process, the ore will be crushed and ground utilizing existing equipment at the Bogoso processing plant. A combination of flotation and gravity circuits, including circuits already at the Bogoso processing plant, will then separate a sulfide concentrate from the ore slurry with the gold locked in the matrix of the sulfide minerals. The bacteria used in the BIOX process oxidize the sulfide minerals in the concentrate thereby liberating the gold particles which are then recovered by cyanidation. The bacteria used in the BIOX process are non-pathogenic and pose no health risks.

The BIOX process has been successfully employed since the mid 1980s with five operations now using the process worldwide including Ashanti Goldfields Company Limited’s Obuasi gold mine located 100 kilometers north of Bogoso. The Obuasi mine is currently treating approximately 1,000 tonnes of sulfide concentrates per day with gold recoveries averaging 92%. Two new BIOX processing plants are currently in construction, one in Australia and one in Kazakhstan. While all plants constructed to date have reached design capacity in less than three months after start-up, there is no assurance that we will achieve similar results.

BIOX bench and pilot scale tests on Bogoso sulfide ores have consistently yielded gold recoveries in excess of 86%. This compares to 55% achievable by direct cyanide treatment. The cost of BIOX treatment is estimated to be

31

Table of Contents

approximately $10.40 per tonne of ore processed. This is higher than the current operating costs for oxide ores at Bogoso, but is expected to be cost effective when compared to other options for treating refractory sulfide ores.

The Bogoso/Prestea expansion plans outlined above are subject to the completion of technical studies now underway, subsequent board approval, obtaining all requisite environmental permits and successful resolution of potential technical difficulties that could be encountered during the construction and start-up of the new facilities.

Geology at Bogoso/Prestea

The Bogoso/Prestea property lies within the Eburnean Tectonic Province in the West African Precambrian Shield. Prestea covers a 22 kilometers stretch of the Ashanti Trend located immediately south of Bogoso. The area is dominated by a major northeast-southwest trending structural fault zone referred to as the Ashanti Trend, which hosts the Prestea, Bogoso, Obuasi and Konongo gold deposits, among others. Parallel to the Ashanti Trend is the Akropong Trend, which hosts the Ayanfuri deposit. The Akropong Trend is about 15 kilometers west of the Ashanti Trend in the Bogoso region, and gradually converges with it, converging at Obuasi and forming the basis for the world class Obuasi deposit, owned and operated by Ashanti Goldfields Company Limited.

Operation Results for Bogoso/Prestea

(1) Gold production is shown on a 100% basis, which represents our current beneficial interest in gold production and revenues. Once all capital has been repaid, the Government of Ghana would receive 10% of the dividends from the subsidiaries owning the Bogoso/Prestea and Wassa mines.

Mineral Reserves and Mineral Resources at Bogoso/Prestea

Bogoso/Prestea has proven and probable mineral reserves of 26.4 million tonnes with a grade of 3.25 g/t containing approximately 2.7 million ounces of gold before a reduction for the 10% minority interest. Total measured and indicated mineral resources total 26.8 million tonnes with a grade of 2.50 g/t before a reduction for the 10% minority interest. The current proven and probable mineral reserves should support mining operations for approximately ten years, although we expect the mine life to be extended as we continue to evaluate mineral resources through ongoing exploration efforts. See the Proven and Probable Mineral Reserves table and the Non-Reserves — Measured and Indicated Mineral Resource table in Item 1 of this 10-K.

Exploration Activities at Bogoso/Prestea

Exploration activities at Prestea during 2003 successfully delineated additional mineral resources and mineralization at the southern end of the Prestea property. Following up on gold in soil anomalies defined in 2002, four meter deep auger drilling was conducted during the first half of 2003. The four meter auger program helped to define the traces of gold in the soil and confirmed the existence of mineralized structures below one meter. Areas where deep auger drilling confirmed subsurface gold mineralization was tested further with drilling. Drilling programs have involved two drill rigs, one stepping out on 100 meter spacing and the second drill rig infilling on 50 meter spacing. The drilling program thus far has tested two sub-parallel zones along a combined strike length of seven kilometers. During 2003 we spent $1.6 million on exploration and completed approximately 42,000 meters of drilling. During 2004 we plan to spend approximately $4.3 million on approximately 118,000 meters of drilling at Bogoso/Prestea.

DEVELOPMENT STAGE PROJECT

The Wassa Development Project

Overview of the Wassa Project

In September 2002 we acquired a 90% interest in the Wassa gold property located 35 kilometers east of our Bogoso/Prestea gold operations in Ghana and immediately began a drilling program and engineering studies designed to evaluate the economic viability of the property as a conventional 10,000 tonnes per day CIL gold operation. Based on initial drill results and engineering data, a feasibility study was begun shortly after acquisition and was completed in July 2003. In July 2003 we announced that the project would proceed and that construction of the CIL processing plant would commence immediately. The feasibility study was prepared by our staff supported by a team of independent consultants led by Metallurgical Design and Management (Pty) Ltd. (“MDM”) of South Africa. In July 2003 we also awarded a fixed-price contract to MDM to construct the new CIL plant and associated processing facilities.

Wassa is owned by WGL, one of our 90% owned Ghanaian subsidiaries. As with Bogoso/Prestea, the Government of Ghana holds a 10% carried interest and is not required to contribute any development capital. Any future dividends (none have been declared to date) would be split 90% and 10% between us and the Government of Ghana, respectively. Dividend payments are not anticipated until WGL has repaid all capital.

The first phase of the Wassa development is now nearing completion. As of December 31, 2003 development costs totaled $27.4 million including the feasibility study cost, equipment and construction cost. In October 2003 we paid an additional $11.5 million to buy out all the debt and royalty obligations due the sellers. Phase two development, which is expected to cost $17.3 million, would consist of the purchase of a mining fleet and the commencement of mining and is scheduled to occur early in 2005.

Wassa is scheduled to commence production operations in early 2004 by processing material from the heap leach pads left by the previous owners. Prior to Golden Star’s acquisition, Wassa was operated as an open pit, heap leach operation. Early reprocessing of this material will make the leach pad area available for tailings containment. Construction of the processing plant and CIL circuit is well underway, and the construction of the tailings dam is scheduled for early 2004. The existing powerhouse at Wassa is being supplemented to allow Wassa to generate 100% of its own power requirements in the early stages of the project’s life until a connection to the local power grid is completed during 2004.

Total production from Wassa is expected to be in the range of 50,000 to 55,000 ounces of gold during 2004 at a cash operating cost of approximately $200 to $240 per ounce. Open pit mining is scheduled to commence early in 2005 when processing of the heap leach material is nearing exhaustion. When operating at the planned capacity of 3.5 million tonnes of ore per year on new ore mined from the open pit, gold production is expected to average 140,000 ounces per year, at an average cash operating cost of approximately $200 per ounce.

Wassa was initially developed in the late 1990’s by a consortium of European mining companies and consisted of an open pit mine and a conventional heap leach operation. While operating as a heap leach property, Wassa produced approximately 90,000 ounces of gold per annum for a period of just over two years beginning in 1999 and ending in mid-2001.

Geology at Wassa

Wassa lies within the Eburnean Tectonic Province in the West African Precambrian Shield. The proterozoic rocks that comprise most of the West African craton and host the major gold mineralization in Ghana are subdivided into metasedimentary and volcanic rocks of the Birimian, and Tarkwaian sequences.

Wassa is hosted within the same Birimian volcano-sedimentary greenstone package as Bogoso/Prestea. Wassa is situated on the southeastern limb of the Tarkwa Syncline while Bogoso and Prestea occur along the northwestern limb. The northwestern belt hosts the Obuasi, Prestea, and Bogoso gold mines but the southeastern limb also is characterized by gold mines and mineral occurrences. Tarkwaian hosted deposits along the south eastern limb include Goldfield’s Tarkwa and Abosso mines, while Birimian hosted gold occurrences include St. Jude’s Hwini-Butre property and Wassa.

Mineral Reserves and Mineral Resources at Wassa

Wassa has a probable mineral reserve of 16.2 million tonnes with a grade of 1.28 g/t containing approximately 0.7 million ounces of gold before the reduction for the 10% minority interest. Total measured and indicated mineral resources consist of 9.4 million tonnes with a grade of approximately 0.96 g/t before a reduction for the 10% minority interest. The current mineral reserves should support mining operations for approximately five years at planned mining rates. See the Proven and Probable Mineral Reserves table and the Non-Reserves - - Measured and Indicated Mineral Resource table in Item 1 of this 10-K.

Exploration Activities at Wassa

Exploration at Wassa during 2003 concentrated on upgrading the mineral resources contained within and around the current engineered pits as well as delineation of mineral resources at a new discovery site approximately 2 kilometers from the Wassa processing plant, called South Akyempim. A total of approximately 21,000 meters of drilling was completed during 2003. Soil and stream sampling of the Adasse prospecting license, located just north of Wassa, was also completed in 2003. Initial results from Adasse were marginal, but results would be evaluated further to see if any additional follow-up work is warranted. Two of the three reconnaissance permits applied for in 2003 are awaiting final approval from the Government of Ghana and work is expected to commence during the first half of 2004.

Drilling of the first of several gold exploration targets on the Wassa property in Ghana has resulted in the discovery of a new higher-grade zone intersected with 15 drill holes to date. The new mineralized zone, located approximately 2 kilometers southwest of the Wassa mill has an average drill width and gold assay of approximately seven meters at 3.1 grams per tonne at depths between the surface and 165 meters below the surface. Additional drilling is planned for 2004 to follow up on this initial drilling campaign. The new zone, which is called South Akyempim, was identified in the drilling of the first of six geochemical targets which exist in two parallel trends running in a southwesterly direction over a strike length of approximately six kilometers, south of the known reserves at Wassa.

EXPLORATION STAGE PROPERTIES IN GHANA

Prestea Underground

Overview

Prestea Underground is located directly beneath our Prestea property and consists of currently inactive underground workings and support facilities. A program to recondition the two main shafts and their associated hoists for exploration purposes was undertaken during 2002 and 2003. Support facilities include an administrative office, maintenance shops, a warehouse and electrical substations. The former 70 year-old processing plant was dismantled by BGL in 2002 to gain access to the surface mineral reserves now being mined by BGL. Access to the mine site is via a paved road maintained by the Government of Ghana. A rail line connects the town of Prestea to Tarkwa, a major mining supply center approximately 25 kilometers to the east, but there is currently no service on the line. Any potential future production from the Prestea Underground could be trucked to the Bogoso processing plant or planned Bondaye processing plant for processing.

In March 2002 BGL entered into an agreement with Prestea Gold Resources Limited, the former operator of the underground mine, and the Government of Ghana to form a joint venture with BGL as operator and manager, with initial interests of 45%, 45%, and 10%, respectively, to evaluate the Prestea Underground. BGL initially contributed approximately $2.4 million to the joint venture for their initial 45% interest, but since that time BGL has funded all of the refurbishment and geological evaluation expenditures and has increased its interest to approximately 66% at the end of 2003, compared to 54% at the end of 2002.

The Prestea Underground has produced approximately nine million ounces of gold during the last 130 years, the second highest production of any mine in Ghana. The underground workings are extensive, reaching depths of approximately 1,400 meters and extending along a strike length of approximately ten kilometers. Underground workings can currently be accessed via two shafts, one near the town of Prestea and a second approximately four kilometers to the southwest. Underground operations ceased in early 2002, following an extended period of low gold prices.

The Prestea Underground is contained within a mining lease which covers the same area as the surface mining lease granted to BGL in 2001. The surface mining lease extends to a depth of 200 meters below the elevation of the Prestea central shaft collar, while the underground mining lease is restricted to material deeper than 200 meters. The consolidation of the underground mine with the activities of BGL is therefore viewed as a natural progression to the orderly and economic development of the area.

Geology of Prestea Underground

The Prestea deposits are found along the Ashanti Trend which extends over 220 kilometers and which accounts for 80% to 90% of the total quartz lode-hosted gold extracted in Ghana. Other mines located along the same shear are our Bogoso pits, and the Obuasi and Konongo mines owned by others.

Two types of gold hosts have historically been recognized at Prestea: fault-related hydrothermal quartz veins; and disseminated sulfide-hosted gold mineralization associated with metavolcanic pods; the first type of ore was the focus of intense mining during Prestea’s past production. We intend to evaluate both types of mineralization.

Mineral Resources at Prestea Underground

Total inferred mineral resources consist of 1.6 million tonnes with a grade of 8.58 g/t before a reduction for the 41% minority interest. See the Non-Reserves — Inferred Mineral Resource table in Item 1 of this Form 10-K.

Exploration Activities at Prestea Underground

Since the creation of the Prestea Underground joint venture, BGL, as the joint venture manager, has been collating over 100 years worth of data and 15,000 meters of the underground workings have been mapped and digitized and entered into our mine and mineral reserve models. Inferred mineral resources at the Prestea Underground of 1.6 million tonnes grading 8.56 g/t at have been conservatively categorized as inferred until validation sampling and volumetrics have been confirmed.

While awaiting preparation of access to the less developed and less explored lower levels of the Prestea underground workings, we initiated in mid-2003 a series of drill holes at shallower levels where access had already been established. A total of 28 holes were drilled averaging 97 meters in length. These holes were in areas that had received extensive mining and development in the past. While some significant intersections were encountered, no major new mineralized zones were discovered. By the end of 2003 we had obtained access to new areas deeper in the mine where we expect to concentrate our efforts in 2004.

Spending at the Prestea Underground project totaled $3.7 million during 2003, including facility maintenance, engineering, drilling, geologic activities and equipment purchases. Support crews continue to maintain the underground and surface facilities in good working order and assist our underground drilling teams.

The Prestea Underground exploration programs for 2004 will involve drilling from underground and surface sites. Drilling of targets below the extent of the existing mining will be conducted from a series of hanging wall cross cuts on the lower levels of the mine. The underground drilling will test the down dip extension of the high-grade ore zones which were previously exploited.

Akropong Trend Properties

Overview of the Akropong Trend Properties

We have entered into numerous option agreements of properties along the Akropong Trend since the acquisition of BGL in September 1999. All of the mineral properties are located on the Akropong Trend and within approximately 25 kilometers from the BGL plant. In addition to the option agreements, BGL has been granted two prospecting licenses to the south and east of the Akropong Trend and has one application for a prospecting license on the western side of the Trend. The total surface area of the mineral properties covered in the option agreements and applications is approximately 700 square kilometers. The objective of this work is to identify additional mineral reserve opportunities in the immediate vicinity of Bogoso/Prestea that could, in the future, provide additional sources of processing plant feed for the Bogoso or planned Bondaye processing plants. All these projects are at an

early stage of exploration and to date they do not have, and ultimately might not have, proven and probable mineral reserves.

Exploration Activities at Akropong Trend Properties

We spent approximately $1.0 million on Akropong projects during 2003 compared to $0.1 million in 2002. Exploration work for 2003 involved soil geochemistry surveys, mechanized trenching, and drilling to delineate the source of the alluvial gold defined by the stream sampling program initiated in 2002. Pending positive results from the soil geochemistry, these anomalies will be drilled in 2004.

Dunkwa Properties

Overview of the Dunkwa Properties

In 2003 we purchased two prospecting licenses, Asikuma and Mansiso, along the Ashanti Trend from Birim Goldfields Inc., which we refer to as the Dunkwa properties. These properties cover 45 kilometers of strike along the Ashanti Trend directly north of and contiguous with the current Bogoso Mining Lease. The addition of the Asikuma and Mansiso prospecting licenses, which cover 56 and 69 square kilometers, respectively, increases our property holdings along this trend to over 100 kilometers in length. In 2003 we also acquired from Ashanti Goldfields Company Limited the rights to the Mampon prospect located on the Asikuma license.

Past and present prospects located on the Dunkwa concessions have been explored during the 1930s to the present day. Several prospects were discovered in the early 1930s and consist of discontinuous gold-bearing quartz veins up to 4m wide with limited known mineralization in the wall rocks. The Mampon prospect was discovered in 1988 using regional geochemical methods and consists of narrow quartz veins with strong pyrite and arsenopyrite mineralization in the wall rocks ranging up to 15% total sulfides. These prospects are also associated with shearing and/or graphitic faults, similar to those seen at Bogoso. There are five known gold prospects on the Dunkwa concession. All of these occur in the same approximate stratigraphic position within Lower Birimian sediments from 1 to 1.5 kilometers west of the contact with the Birimian metavolcanics.

Exploration Activities at the Dunkwa Properties

During 2003 exploration activities included infill soil geochemistry and establishing drill access. Exploration for 2004 is expected to involve drilling over the known occurrences as well as follow up drilling of any new targets generated. The Mampon mineral reserves, located within the Dunkwa prospecting licenses, add approximately 0.9 million tonnes of probable mineral reserves grading 5.61 g/t of gold containing approximately 0.2 million ounces of gold. At December 31, 2003 the indicated mineral resource on the Dunkwa properties was 0.4 million tonnes grading 2.79 g/t of gold. In addition, there are approximately 2.4 million tonnes of inferred mineral resource at an average grade of 2.69 g/t of gold. Further mineral resource definition drilling during 2004 is expected to cost $0.7 million.

Obuom Property

In 2003 we reapplied for a prospecting license on the Obuom concession and anticipate that it will be approved in 2004. Exploration work scheduled for Obuom will involve early stage exploration to confirm previous soil geochemical work done by previous owners.

Other Active Properties in Africa

In late 2003 we added 500 and 250 square kilometers of exploration properties in Sierra Leone and Mali, respectively. The related joint venture agreements, which are subject to definitive documentation and government approvals, allow Golden Star to earn in up to 85% and 82.5%, respectively, by sole funding the development of any projects. Firm commitments during the first twelve months of the agreements require us to spend $1.0 million and $0.4 million on the Sierra Leone and Mali properties, respectively. Any further spending will be dependent upon the results of the work done during the commitment period.

In addition to the ongoing exploration on the mining leases and existing prospecting and reconnaissance permits, we are actively targeting prospective areas for potential land acquisitions. Target generation will require the acquisition

and interpretation of geophysical datasets, compilation of data collected by previous explorers, interpretation of high-resolution satellite images and field investigation. Highly prospective areas will be selected from our compilation and interpretation, and we will actively pursue the land position either through joint ventures or staking of available ground.

THE SOUTH AMERICAN PROPERTIES

Overview of the South American Properties

We hold one exploration property in Suriname known as the Saramacca property. Our other properties in South America are located in French Guiana and held through Guyanor, our 73% owned subsidiary. French Guiana is part of French national territory and has been an overseas “Département” of France since 1946. Under the French Constitution, the same laws govern French Guiana as metropolitan France, subject to modifications (including those affecting tax and mining laws and regulations) that could be adopted to reflect the historical, cultural, geographical and economic characteristics of French Guiana and provide for regional administration.

At December 31, 2003 Guyanor owned mineral rights (either directly or through its subsidiaries) for the Yaou, Dorlin, Paul Isnard, and Bon Espoir properties. The Bon Espoir property was acquired in December 2003 and is discussed in more detail below. During 2003 Guyanor spent approximately $0.2 million on care and maintenance of its exploration properties compared to $0.3 million during 2002.

Acquisition of the Bon Espoir Property

In December 2003 Guyanor acquired the Bon Espoir property from Gold Fields Exploration B. V. for a purchase price of $0.3 million payable in stock and warrants. Bon Espoir is located north of the Paul Isnard properties in western French Guiana. The purchase price of approximately $0.3 million will be payable by the issuance of 1.5 million common shares and 1.5 million warrants of Guyanor subject to various shareholder and governmental approvals. The terms of the 1.5 million warrants, which comprise three classes, have exercise prices ranging from €0.21 per share to €0.34 per share, and have expiration dates of one to three years. Additional provisions include a sliding scale royalty ranging from 0.5% to 2.0% of the net smelter returns and a back-in-right to acquire a 65% participating interest in a future gold project on the Bon Espoir property.

The Guiana Shield Transaction

In May 2002 we sold our interests in the Gross Rosebel, Headleys and Thunder Mountain properties in Suriname, and our interest in Omai Gold Mines Limited (“OGML”) in Guyana, to Cambior Inc. We received $5.0 million cash in 2002 and a $1.0 million deferred payment in 2003 from the sale of the Gross Rosebel property. We expect to receive two additional deferred payments of $1.0 million each in 2004 and 2005. In addition, Cambior agreed to pay us a royalty equal to 10% of the excess of the average quarterly market price above a gold price hurdle on the first 7 million ounces of gold production from Gross Rosebel. For soft and transitional rock the gold price hurdle is $300 per ounce and for hard rock the gold price hurdle is $350 per ounce. For the Headleys and Thunder Mountain properties, we are entitled to receive a deferred consideration of $0.5 million each, when and if Cambior commences commercial mining from these properties. As payment for our 30% equity interest and preferred shares in OGML, we received a release and waiver from OGML, Cambior and the Guyana Government in respect of all liabilities, of any nature, related to the Omai gold mine. In the transaction Golden Star also acquired Cambior’s 50% interests in the Yaou and Dorlin exploration properties in French Guiana.

Cambior has stated that Gross Rosebel’s commercial gold production is scheduled to begin in early 2004 and total approximately 245,000 ounces of gold during 2004. Cambior is projecting 220,000 ounces of gold per year average production over the mine’s projected nine year mine life. Based on Cambior’s announced gold production schedule, we expect royalty payments from Gross Rosebel of approximately $2 million in 2004, assuming current gold prices.

Saramacca Property

Two successive soil auger sampling programs were completed in late 2002 and early 2003 to evaluate the 15 to 18 kilometer long by 3 to 5 kilometer wide series of stream sediment gold anomalies. A total of approximately $0.2

37

Table of Contents

million of direct field related costs were spent in each of the 2002 and 2003 field programs. Field work has included establishment of an 18 kilometer long by 4 to 7 kilometer wide auger grid, with 154 kilometers of cut lines. Grid line spacing was 600 to 800 meters with one-meter auger samples taken on 100 meter line spacings.

For 2004, approximately $0.2 million of exploration spending will be focused on a deep augering and mechanized trenching campaign. Positive results would likely be followed up in late 2004 or 2005 with drilling to establish potential subsurface grades, as well as defining limits of the system. The Saramacca property is held directly by Golden Star.

Bon Espoir Property

The area is covered by the Bon Espoir Exclusive Exploration Permit, dated October 24, 2001 and valid until October 31, 2006. This permit covers an area of 466 square kilometers. Financial commitments for the first five-year period of validity ending October 31, 2006, are €3.2 million, of which €0.9 million has already been spent in detailed exploration work on the Wayamaga prospect which lies within the Bon Espoir property (soil geochemistry, drilling). Planned work in 2004 consists of regional soil geochemistry to test the totality of the 40 kilometer long prospective contact.

The Yaou and Dorlin Properties

The Yaou exploration permit covers an area of 52 square kilometers located some 210 kilometers southwest of Cayenne, French Guiana. The Dorlin exploration permit covers an area of 84 square kilometers located some 180 kilometers southwest of Cayenne and 60 kilometers east of Maripasoula. In 2003 the Yaou and Dorlin properties remained on care and maintenance and expenditures totaled less than $0.1 million. There is no significant work planned at Yaou or Dorlin in 2004.

Paul Isnard Property

The Paul Isnard property is located in the western part of French Guiana, approximately 180 kilometers west of Cayenne. The concessions held will expire on December 31, 2018 but can be renewed for an additional 25 years. The Paul-Isnard exploration permit covers an area of 283 square kilometers, and we are waiting for the granting of its first renewal for a reduced surface area. The total area under or awaiting permit is 433 square kilometers. Paul Isnard remained on care and maintenance during 2003 and total costs incurred were less than $0.1 million. There is no significant work planned at Paul Isnard in 2004.

ITEM 3. LEGAL PROCEEDINGS

We have been named as one of 14 defendants in a class action lawsuit filed in the High Court of the Supreme Court of Judicature of Guyana on May 19, 2003 related to the August 1995 accidental release of cyanide-bearing waste into a stream near the Omai gold mine, in which we then owned a 30% equity interest. Other defendants include Cambior Inc., which co-owned and operated the mine in 1995 and to which we subsequently sold the mine in 2002. The plaintiffs claim to represent residents near the stream and its tributaries. The plaintiffs claim various environmental and other damages and have asked for substantial damages, in excess of $1.0 billion, from all defendants, jointly and severally, among other remedies. During the third quarter of 2003 Cambior filed a motion to dismiss the lawsuit. We have not been served with process in this litigation. While we believe this claim is without merit, we cannot reasonably predict the outcome of this litigation. In connection with the sale of our interest in the Omai mine to Cambior in 2002, Cambior indemnified us from any claims related to the mine.

We are not currently subject to any material pending legal proceedings. We are, however, engaged in routine litigation incidental to our business. No material legal proceedings, involving us or our business are pending, or, to our knowledge, contemplated, by any governmental authority. We are not aware of any material events of noncompliance with environmental laws and regulations.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following summarizes the principal Canadian federal income tax considerations applicable to the holding and disposition of a common share of the Company (a “Common Share”) by a holder (the “Holder”) of one or more

40

Table of Contents

Common Shares, for tax purposes, who is resident in the United States of America and holds the Common Shares as capital property. This summary is based on the current provisions of the Canada-United States Income Tax Convention (1980) (the “Treaty”), Income Tax Act (Canada) (the “Tax Act”), the regulations thereunder and all amendments to the Tax Act publicly proposed by the Government of Canada to the date hereof. It is assumed that each such amendment will be enacted as proposed and there is no other relevant change in any governing law, although no assurance can be given in these respects. Limited Liability Corporations cannot access any of the benefits of the Treaty as described in the paragraphs.

Every Holder is liable to pay a withholding tax on every dividend that is or is deemed to be paid or credited to him on his Common Shares. Under the Act, every non-resident person shall pay a tax at 25%. Under the Treaty, the rate of withholding tax is reduced to 5% of the gross amount of the dividend where the Holder is a company that owns at least 10% of our voting stock and beneficially owns the dividend, and 15% in any other case.

Under the Tax Act, a Holder will not be subject to Canadian tax on any capital gain realized on an actual or deemed disposition of a Common Share, including a deemed disposition at death, provided that he did not hold the Common Share as capital property used in carrying on a business in Canada, and that neither he nor persons with whom he did not deal at arm’s length alone or together owned 25% or more of the issued shares of any class of our stock at any time in the 60 month period immediately preceding the disposition.

A Holder who is liable under the Tax Act for Canadian tax in respect of a capital gain realized on an actual or deemed disposition of a Common Share could be relieved under the Treaty from such liability unless:

(a)

the Common Share formed part of the business property of a permanent establishment or fixed base in Canada that the Holder has or had within the twelve-month period preceding the disposition; or

(b)

the Holder was an individual; and

(i)

was resident in Canada for 120 months during any period of 20 consecutive years preceding the disposition; and

(ii)

was resident in Canada at any time during the ten years immediately preceding the disposition; and

(iii)

owned the Common Share when he ceased to be a resident of Canada.

This summary is of a general nature and is not intended, nor should it be construed, to be legal or tax advice to any particular Shareholder. SHAREHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISERS AS TO THE INCOME AND OTHER TAX CONSEQUENCES ARISING IN THEIR PARTICULAR CIRCUMSTANCES.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

Potential investors that are US taxpayers should consider that we could be considered to be a “passive foreign investment company” (“PFIC”) for federal income tax purposes. Although we believe that we currently are not a PFIC and do not expect to become a PFIC in the near future, the tests for determining PFIC status are dependent upon a number of factors, some of which are beyond our control, and we can not assure you that we would not become a PFIC in the future. If we were deemed to be a PFIC, then a US taxpayer who disposes or is deemed to dispose of our shares at a gain, or who received a so-called “excess distribution” on the shares, generally would be required to treat such gain or excess distribution as ordinary income and pay an interest charge on a portion of the gain or distribution unless the taxpayer makes a timely qualified electing fund election (a “QEF” election). A US taxpayer who makes a QEF election generally must report on a current basis his or her share of any of our ordinary earnings and net capital gain for any taxable year in which we are a PFIC, whether or not we distribute those
