Exhibit 99.1

NovaCopper and Sunward Announce Arrangement

VANCOUVER, April 23, 2015 /CNW/ - NovaCopper Inc. (TSX, NYSE-MKT: NCQ) ("NovaCopper") and Sunward Resources Ltd. (TSX: SWD; OTCQX: SNWRF) ("Sunward") are pleased to announce that they have entered into a definitive arrangement agreement (the "Arrangement Agreement") pursuant to which NovaCopper has agreed to acquire all of the issued and outstanding common shares of Sunward by way of a court approved plan of arrangement (the "Arrangement").

The combination of NovaCopper and Sunward will create a leading exploration and development company with a strong balance sheet of approximately US$23 million in cash for the advancement of the Arctic and Bornite deposits located in the Ambler mining district of Alaska, USA.  The company plans to advance the Arctic deposit towards feasibility with a US$8-10 million field program this summer.  Meanwhile, plans are underway to maximize shareholder value at the Titiribi exploration asset in Colombia.  Sunward has focused on community engagement at its Titiribi project and with its talented and experienced Colombian management team, has built a strong reputation with local communities.

Under the terms of the Arrangement, Sunward shareholders will receive 0.3 (the "Exchange Ratio") of a NovaCopper common share ("NovaCopper Share") for each Sunward common share ("Sunward Share") held.  The Exchange Ratio represents the equivalent of US$0.1841 per Sunward Share based on the closing price of the NovaCopper Shares on the NYSE MKT LLC ("NYSE-MKT") as of April 22, 2015 and represents the equivalent of US$0.1865 per Sunward Share based on the 20-day volume weighted average price ("VWAP20") of the NovaCopper Shares on the NYSE-MKT as of the same date.  The Exchange Ratio implies a total transaction value of approximately US$27.6 million on a VWAP20 basis, including the automatic vesting and exchange into NovaCopper Shares of Sunward's outstanding deferred share units, and the exercise of in-the-money stock options for NovaCopper Shares.  Outstanding Sunward options will be converted at the Exchange Ratio, and shall expire 90 days following the completion of the Arrangement.

NovaCopper has received voting support agreements from all Sunward officers and directors.  Additionally, Sunward's four largest shareholders, including Gold First Investments Limited, Electrum Strategic Acquisitions LLC and Paulson & Co. Inc., who hold, in aggregate, approximately 70% of Sunward's issued and outstanding Shares, have all agreed to vote in support of the Arrangement at Sunward's special meeting of shareholders expected to be held in June or July.  

Upon completion of the Arrangement, the combined company will be owned approximately 58% by NovaCopper shareholders and 42% by Sunward shareholders.

Highlights and Benefits of the Combined Company

"The combination of Sunward and NovaCopper provides shareholders a single company with a strong balance sheet to advance critical path objectives at our high quality Arctic and Bornite copper-zinc assets in Alaska.  It also gives the company significant exposure and leverage to additional gold and copper in Colombia.  Within the context of a market place which is demanding consolidation but is challenging for development project financing, management believes this is a win-win solution for all shareholders" said Rick Van Nieuwenhuyse, NovaCopper's President and Chief Executive Officer.

Sunward's Chief Executive Officer, Philip O'Neill said, "I believe this business combination gives our shareholders exposure to a very high quality asset located in a mining friendly jurisdiction, and we feel NovaCopper's exploration team, with its demonstrated track record of success, will be able to add value to both the Ambler and Titiribi assets."

Transaction Summary

The implementation of the Arrangement is subject to the approval of at least 66 2/3% of the votes cast by holders of Sunward Shares and, if required under applicable securities laws, a majority of disinterested Sunward shareholders, at a special meeting of Sunward shareholders expected to take place in early summer 2015.  Issuance of the NovaCopper Shares in the Arrangement is also subject to the approval of a majority of the votes cast by the holders of NovaCopper Shares at a special meeting of NovaCopper shareholders expected to take place on or about the same date.  In addition to shareholder approvals, the Arrangement is also subject to the receipt of certain regulatory, court and stock exchange approvals and certain other closing conditions customary in transactions of this nature.

The Arrangement Agreement has been unanimously approved by the board of directors of each of Sunward and NovaCopper, two common directors having declared their interest and abstained from voting.  Dr. Thomas Kaplan, a director of NovaCopper, also declared his interest and abstained from voting due to his relationship with Electrum Strategic Resources L.P., which owns approximately 27.8% of NovaCopper's issued and outstanding shares, and whose affiliated fund owns approximately 18.2% of Sunward's issued and outstanding shares.

Haywood Securities Inc. has provided an oral fairness opinion to the Special Committee of the board of directors of NovaCopper that, subject to the assumptions, limitations and qualifications set out in such fairness opinion, the consideration to be paid by NovaCopper pursuant to the Arrangement is fair, from a financial point of view, to NovaCopper.  Cormark Securities Inc. has provided a fairness opinion to the Special Committee of the board of directors of Sunward that, subject to the assumptions, limitations and qualifications set out in such fairness opinion, the consideration to be received by Sunward shareholders in connection with the Arrangement is fair, from a financial point of view, to such Sunward shareholders.

Cautionary Note Regarding Forward-Looking Statements

This press release includes certain "forward-looking information" and "forward-looking statements" (collectively "forward-looking statements") within the meaning of applicable Canadian and United States securities legislation including the United States Private Securities Litigation Reform Act of 1995.

Forward-looking statements are frequently, but not always, identified by words such as "expects", "anticipates", "believes", "intends", "estimates", "potential", "possible", and similar expressions, or statements that events, conditions, or results "will", "may", "could", or "should" occur or be achieved. These forward-looking statements may include statements regarding perceived merit of properties; exploration plans and budgets; mineral reserves and resource estimates; work programs; capital expenditures; timelines; strategic plans; market prices for precious and base metals; or other statements that are not statements of fact.

These forward-looking statements are based on a number of assumptions, including assumptions regarding the ability of the parties to receive, in a timely manner and on satisfactory terms, the necessary court, shareholder, stock exchange and regulatory approvals and the ability of the parties to satisfy in a timely manner, the conditions to the closing of the Arrangement; the value of NovaCopper and Sunward's respective assets; the successful advancement of exploration projects, planned expansions or other projects within the timelines anticipated and at anticipated production levels; projections and estimates made in the technical reports for the UKMP and Titiribi projects; that mineral resources can be developed as planned; interest and exchange rates; that required financing will be obtained and on market terms; general economic conditions; that labour disputes, flooding, ground instability, fire, failure of plant, equipment or processes to operate as anticipated and other risks of the mining industry will not be encountered; the price of copper and other metals; competitive conditions in the mining industry; title to mineral properties; and changes in laws, rules and regulations applicable to NovaCopper and Sunward.  Although management of NovaCopper and Sunward believe that the assumptions made and the expectations represented by forward-looking statements contained herein are reasonable, there can be no assurance that such statements will prove to be accurate.

Forward-looking statements involve various risks and uncertainties. There can be no assurance that such statements will prove to be accurate, and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from NovaCopper's and Sunward's expectations include the uncertainties involving the need for additional financing to explore and develop properties and availability of financing in the debt and capital markets; uncertainties involved in the interpretation of drilling results and geological tests and the estimation of reserves and resources; the need for cooperation of government agencies and native groups in the development and operation of properties; the need to obtain permits and governmental approvals; risks of construction and mining projects such as accidents, equipment breakdowns, bad weather, non-compliance with environmental and permit requirements, unanticipated variation in geological structures, metal grades or recovery rates; unexpected cost increases, which could include significant increases in estimated capital and operating costs; and fluctuations in metal prices and currency exchange rates.  NovaCopper's and Sunward's forward-looking statements reflect the beliefs, opinions and projections on the date the statements are made.  Readers are cautioned not to place undue reliance on forward-looking information due to the inherent certainty thereof.  NovaCopper and Sunward assume no obligation to update the forward-looking statements or beliefs, opinions, projections, or other factors, should they change, except as required by law.

Cautionary Note to United States Investors

Sunward's resource information has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resource and reserve estimates included in this press release have been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the SEC, and resource and reserve information contained therein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, the term "resource" does not equate to the term "reserves". Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. The SEC's disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by U.S. standards in documents filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. U.S. investors should also understand that "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 resource" will ever be upgraded to a higher category. Under Canadian rules, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. Investors are cautioned not to assume that all or any part of an "inferred mineral resource" exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in-place tonnage and grade without reference to unit measures. The requirements of NI 43-101 for identification of "reserves" are also not the same as those of the SEC, and reserves reported by the Company in compliance with NI 43-101 may not qualify as "reserves" under SEC standards. Accordingly, information concerning mineral deposits set forth in this press release may not be comparable with information made public by companies that report in accordance with U.S. standards.
