General Moly Announces Liberty Project Drill Hole Results Ahead of Revised Resource Estimate

Long Intervals of High-Grade Molybdenum Intersected

LAKEWOOD, Colo.--(BUSINESS WIRE)--July 5, 2011--General Moly (NYSE Amex and TSX: GMO) announced the results of 33 core holes that were not previously included in the Liberty project's 2008 pre-feasibility study.

Bruce D. Hansen, Chief Executive Officer, said, "As part of our effort to re-start project development activities at the Liberty project this year, I am pleased to release these encouraging drill results from our second, world-class moly property. In addition to ongoing permitting achievements that we anticipate at the Mt. Hope project in the second half of the year, we are also advancing the Liberty project and anticipate releasing a revised resource estimate in the third quarter, as well as an updated pre-feasibility study early next year. Liberty is a solid project with robust economics for which we feel we receive minimal market valuation; however I am confident that we will continue to build value for our shareholders by driving both Mt. Hope and Liberty project development."

Highlights of the 33 holes include 19 holes that had at least one moly mineralization interval of greater than 200 feet and in excess of 0.100% moly contained in sulfide mineralization. These long, high-grade intervals range in length from 240 feet to 1,239 feet and range in grade from 0.1049% to 0.2419% moly contained in sulfide mineralization. These 19 holes are summarized in the following table and additional drill hole information is reported as an appendix to this release. Complete assay results are available on the Company's website.

The following table highlights the independent intervals with total copper in excess of 0.2% over a distance of greater than 50 feet with associated moly grades contained in sulfide mineralization.

These 33 holes were principally focused on demonstrating in-fill continuity, increasing metallurgical understanding and examining ore body extensions to the east and at depth. These holes augment a pre-existing database containing information from 716 holes previously drilled by Anaconda, Cyprus Minerals, Equatorial, and General Moly. This drilling information, combined with updated modeling parameters, will form the basis for a revised Liberty NI 43-101 compliant resource estimate, which is anticipated to be completed in the third quarter of the year. The revised resource estimate will be utilized in an updated pre-feasibility study that is anticipated to be completed in the first quarter of 2012. The prior 2008 NI 43-101 compliant pre-feasibility study indicated 433 million minable tons at grades of 0.068% moly contained in sulfide mineralization and 0.070% total copper, resulting in 589M pounds of moly contained in sulfide mineralization and 606M pounds of total copper contained in the proven and probable category.

A cross section of the deposit as well as a plan view map illustrating the location of the 33 holes can be accessed on the Company's website at www.generalmoly.com under the "news" section. An appendix to this release includes further drill hole information including drill hole location, azimuth, inclination, and total depth. A complete table of drill results, including assays for both moly contained in sulfide mineralization and total copper can also be accessed on the Company's website.

Mark W. Osterberg, President of Mine Mappers, L.L.C.., of Tucson, Arizona, and a Registered Professional Geologist is the Qualified Person responsible for the collection and evaluation of geologic data (including Drilling, Sampling, Assaying, and Geological Interpretation) pertaining to the Liberty project.

General Moly is a U.S.-based molybdenum mineral development, exploration and mining company listed on the NYSE Amex (formerly the American Stock Exchange) and the Toronto Stock Exchange under the symbol GMO. Our primary asset, our interest in the Mt. Hope project located in central Nevada, is considered one of the world's largest and highest grade molybdenum deposits. Combined with our second molybdenum property, the Liberty project that is also located in central Nevada, our goal is to become the largest primary molybdenum producer by the middle of the decade.

Cautionary Note to U.S. Investors Concerning Estimates of Resources

Calculations with respect to “proven reserves” and “probable reserves” referred to above have been made in accordance with, and using the definitions of, National Instrument 43-101, as required by Canadian securities regulatory authorities. For United States reporting purposes, the U.S. SEC applies a different standard in order to classify mineralization as a “reserve”. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally extracted or produced at the time the reserve determination is made. No such determinations have been made with respect to any mineralization at the Liberty project and it cannot be assured that such a determination will be made.
