Geovic Mining Corp. Announces Update on Wind Mountain Project, New Mexico

May 20, 2014 - Denver, CO - Geovic Mining Corp. ("Geovic" or "the Company", TSX:GMC, OTCBB:GVCM) is pleased to announce an update on its Wind Mountain Project (the “Project”) in New Mexico.

Geovic holds the following equity interests in various exploration projects: a 60.5 percent interest in the advanced Geovic Cameroon PLC Cobalt-Nickel-Manganese Project in Cameroon; a 100 percent interest in Geovic Nouvelle Caledonie SAS’s Chromite Project in New Caledonia; a 100 percent interest in Geovic’s Chromite Project in Papua New Guinea; a 100 percent interest in Geovic’s Arizona Gold Project; and a 10 percent interest in the Wind Mountain Rare Metals Project in New Mexico.

Geovic has completed a joint venture agreement with the JS Group, LLC (“JS”) of Casper Wyoming, pursuant to which JS has paid Geovic USD 300,000 to increase JS’s equity interest in the Project and has committed to the non-refundable expenditure of USD 435,000 towards a scoping study currently being developed by Geovic. Consequently, JS now holds a 90% interest in the Project, with Geovic retaining a repurchase right to earn back up to a 25% interest in the Project by refunding USD 300,000 to JS before assaying drill core from the upcoming drill program.

Positive results have been obtained from the phase-I program, covering preliminary metallurgical testing and a pre-scoping economic study funded by JS. It should be noted that the potential grade is conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource. The basis on which the potential grades have been determined is an independent laboratory assay and analysis of samples indicating an advanced metal suite with the potential to contain zirconium, rare earths and other related advanced metals.

The planned upcoming drill program will include up to 28 angle drill holes positioned from seven sites on the eastern margin of the Project. Prior surface sampling has identified potentially significant concentrations of rare earths, niobium, tantalum, gallium, zirconium and hafnium (Table 1). The program is designed to define advanced metal resources and provide material for metallurgical testing for a scoping study. The program is planned to begin in a few weeks following this announcement. Results of this drill program will be released once assay results are obtained from the drill core.

The range of analyses of Project surface samples analyzed by the independent laboratory Actlabs in Toronto Canada is provided in Table 1 as follows.
