GENERAL MOLY ANNOUNCES PUBLICATION OF THE MT. HOPE PROJECT’S DRAFT ENVIRONMENTAL IMPACT STATEMENT

LAKEWOOD, COLORADO — December 5, 2011, General Moly, Inc. (the “Company”) (NYSE Amex and TSX: GMO) announced that on Friday, December 2, 2011, the Bureau of Land Management (“BLM”) published the Mt. Hope project’s Notice of Availability (“NOA”) in the Federal Register, commencing the public comment period for the Mt. Hope project’s Draft Environmental Impact Statement (“DEIS”).

Bruce D. Hansen, Chief Executive Officer, said, “The publication of the Mt. Hope DEIS is one of our most significant permitting accomplishments in the last five years and I am extremely pleased with and proud of our team for their continued efforts toward this goal.  We believe the Mt. Hope project’s DEIS is extremely robust and defensible and will continue to assist the BLM to the extent possible in finalizing the Final EIS for the project.

I would also like to commend the State and Federal offices of the BLM for their efforts in expediting the Notice of Availability process for this project.  A process that has historically taken 3 months or longer was accomplished in less than 1 month, in large part due to the administrative efforts of the BLM offices to expedite projects.

Finally, I would like to encourage those who support the Mt. Hope project to participate in the public comment process and submit supportive comments to the BLM over the next 90 days.”

The 90-day public comment period will close during the first week of March 2012, and currently includes one public hearing in Eureka, Nevada scheduled for January 18, where the BLM will present the Mt. Hope project and the BLM’s findings.  Following the public comment period, the BLM will consider comments received in developing a Final Environmental Impact Statement (“FEIS”).  The Company anticipates the Mt. Hope Record of Decision (“ROD”) to be issued following the FEIS, which will allow construction to proceed.  In all, the Company anticipates to receive its final permits within 6-9 months, or June to September 2012.
