GEOVIC CAMEROON SIGNIFICANTLY INCREASES RESOURCES AT NKAMOUNA COBALT PROJECT October 16, 2009 � Denver, CO - Geovic Mining Corp. (�Geovic� or �the Company�, TSX:GMC, OTC.BB:GVCM), on behalf of its 60.5%-owned subsidiary Geovic Cameroon PLC (�GeoCam�), is pleased to announce that estimated resources at its Nkamouna cobalt-nickel-manganese project in Cameroon, Africa have significantly increased following an extensive 2008 drilling program, encompassing 2,045 holes totaling 54,900 meters. The expanded resource base should enable GeoCam to selectively mine higher grade ore during the early years of production, substantially extend the project�s mine life, and further establish GeoCam�s position as the world�s largest primary cobalt resource holder. Results represent combined totals for the neighboring Nkamouna and Mada mineral deposits, both of which are within economic transport distance from the location of the proposed process plant. Resource Update Highlights � Measured and Indicated resources increased 97% to 120.6 million tonnes, grading 0.23% cobalt, 0.65% nickel, and 1.34% manganese. � Inferred resources increased 25% to 202.5 million tonnes, grading 0.20% cobalt, 0.59% nickel, and 1.20% manganese. � The January 2008 estimate of Nkamouna�s Proven and Probable reserves, at 54.7 million tonnes grading 0.25% cobalt, 0.69% nickel, and 1.33% manganese, was projected to support a 19-year mine life. The approximate doubling in Measured and Indicated resources suggests the potential to double this period. � Nkamouna and Mada represent roughly 19% of the mineralized area covered by GeoCam�s mine permit (as depicted by geologic maps), intimating significant upside potential to these estimates. � Updated Proven/Probable reserve estimates at Nkamouna, initial Proven/Probable estimates at Mada, and an initial resource estimate at the adjacent Rapodjombo property, are anticipated to be completed in early 2010. � The updated reserve estimates should enable application of higher cutoff grades in the mine plan, thereby yielding materially improved economics in the forthcoming Feasibility Study Update, due to be completed by mid-2010. Nkamouna-Mada 2008 Drilling Program During 2008, a 2,045-hole, 54,900 meter drill program was completed to accomplish the following: � Reduce the distance between the earlier holes at Nkamouna and Mada, thereby adding greater certainty to resource estimates � More fully delineate the lateral and vertical extents of previous reserve and resource estimates � Reclassify significant amounts of Indicated and Inferred resources to the more certain Measured category � Initiate a resource estimate at the adjoining Rapodjombo property At Nkamouna, 975 drill holes averaging 26 meters in depth were completed, while at Mada 1,012 holes were completed averaging 23 meters. Additionally, 248 holes were completed at Rapodjombo to enable commencement of work on an initial resource estimate. Nkamouna-Mada Resource Comparison � January 2008 vs. October 2009 Below is a summary comparison of the cobalt, nickel, and manganese resources at Nkamouna and Mada in the January 2008 NI 43-101 Technical Report and the updated October 2009 resource estimate, both of which include GeoCam�s previously announced reserves. An NI 43-101 Technical Report incorporating the new resource estimates is anticipated to be completed in November 2009. | | | As of January 2008 1 | As of October 2009 2 | Resource | | | Tonnes | Average Grades, % | Tonnes | Average Grades, % | Class | Property | | (millions) | Co | Ni | Mn | (millions) | Co | Ni | Mn | | | | | | | | | | | | Measured | Nkamouna | | 31.5 | 0.26 | 0.67 | 1.35 | 59.8 | 0.24 | 0.68 | 1.37 | | Mada | | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | | | | 31.5 | 0.26 | 0.67 | 1.35 | 59.8 | 0.24 | 0.68 | 1.37 | | | | | | | | | | | | Indicated | Nkamouna | | 29.9 | 0.22 | 0.66 | 1.17 | 20.9 | 0.19 | 0.67 | 1.12 | | Mada | | 0 | 0 | 0 | 0 | 39.9 | 0.23 | 0.59 | 1.43 | | | | 29.9 | 0.22 | 0.66 | 1.17 | 60.8 | 0.22 | 0.62 | 1.32 | | | | | | | | | | | | Total Measured/Indicated | 61.3 | 0.24 | 0.66 | 1.26 | 120.6 | 0.23 | 0.65 | 1.34 | | | | | | | | | | | | Inferred | Nkamouna | | 17.4 | 0.18 | 0.55 | 1.06 | 19.9 | 0.19 | 0.65 | 1.09 | | Mada | | 145.1 | 0.21 | 0.48 | 1.15 | 182.6 | 0.20 | 0.58 | 1.21 | | | | | | | | | | | | Total Inferred | | 162.5 | 0.21 | 0.49 | 1.14 | 202.5 | 0.20 | 0.59 | 1.20 |
