General Moly Announces Approval of 3M Plan for Mt. Hope Project

LAKEWOOD, Colo.--(BUSINESS WIRE)--June 11, 2012--General Moly, Inc. (the "Company") (NYSE MKT and TSX: GMO) today, through a subsidiary, announced the approval of the Mt. Hope Project's 3M Plan (Monitoring, Management and Mitigation) by the Nevada State Engineer (the "State Engineer").

The 3M Plan is a key document that outlines how the Mt. Hope Project's water use will be managed and monitored by the Company and the State Engineer with the participation of Eureka County and other stakeholders. The 3M Plan provides mitigation protections if impacts are caused by the Mt. Hope Project. The Company completed and initially submitted its 3M Plan to the State Engineer on May 10, 2012, following input from Eureka County, and its citizens through public meetings.

In July 2011, the State Engineer granted the Company's water use applications for the Mt. Hope Project and issued water permits in December 2011 and January 2012. Use of water under the permits was subject to approval of a 3M Plan. With its water permits and approval of the 3M Plan, the Mt. Hope Project can now utilize its water rights during construction and operation. The State Engineer's Ruling remains under appeal by Eureka County and other parties. Oral argument on the appeal was heard by a Nevada District Court on April 3, 2012.

Bruce D. Hansen, Chief Executive Officer of General Moly, said, "We are continuing to make good progress toward permitting the Mt. Hope Project and approval of the 3M Plan is another step in this direction. The community of Eureka County had substantial input in developing this robust 3M Plan and I am pleased with the result. Although our water permits remain subject to an appeal, we look forward to the Court's ruling, which could be in the next couple months."
