Geovic Mining Announces Key Construction Management Appointments at Nkamouna

VANCOUVER, BRITISH COLUMBIA, May 20 (MARKET WIRE) --
Geovic Mining Corp. ("Geovic" or "The Company") (TSX: GMC), on behalf of
its 60%-owned subsidiary Geovic Cameroon PLC (GeoCam), is pleased to
announce three key appointments as it rapidly moves toward construction
of its Nkamouna Cobalt-Nickel-Manganese project in Cameroon, Africa.

Johann du Preez has been appointed Construction Manager, and is charged
with overseeing all major construction at Nkamouna, currently scheduled
to commence in late 2008. Mr. du Preez has more than 30 years experience
as a construction manager, principally with African mineral processing
plants and infrastructure improvements. He has overseen 18 separate
projects totaling U.S. $5.4 billion, last working as resident
construction manager at the Kolwezi copper/cobalt project in the
Democratic Republic of Congo. As Kolwezi is expected to be one of the
world's largest copper/cobalt processing plants, Mr. du Preez is uniquely
qualified to enhance the engineering and design of Nkamouna, and
subsequently lead its construction effort.

Anthony Mills has been appointed Engineering Project Manager to serve as
GeoCam's primary liaison and representative to the engineering and design
Alliance, consisting of Bateman International Projects BV, Roberts &
Schaefer Australia Pty. Ltd., and Group Five Projects Pty. Ltd. The

recently located, and is continuing under a Professional Service
Agreement that has been extended until negotiations are complete on a
comprehensive engineering, procurement and construction management
agreement between the Parties. Mr. Mills has more than 40 years of
experience in project management, engineering, and construction,
including more than 30 years with mining and mineral processing projects.
Mr. Mills previously served as Project Manager with engineering and
construction companies specializing in the mineral industry, including
Fluor, Mineral Resource Development Inc., and Kvaerner.

Andrew Ramcharan has been appointed Manager, Technical Services, based in
the Company's home office in Grand Junction, Colorado. His primary
responsibility will be optimization of the Cameroon mining plans, and
secondarily to assist Geovic in the evaluation of new projects. Mr.
Ramcharan has more than 10 years experience as a Mining Engineer/Analyst,
specializing in three-dimensional geologic modeling, resource/reserve
estimation, and all aspects of project planning/execution. A graduate of
and PhD candidate from the Colorado School of Mines, he has already
worked on more than 50 projects in five continents.

David Beling, COO of Geovic comments, "These appointments will markedly
advance the development, construction and production phases at Nkamouna.
We look forward to commencing major construction in late 2008, and are
very excited by the caliber of professionals we have added to our
expanding team."
