CAMEROON :A NEW MINING
DESTINATION IN AFRICA
By Hon. SECRETARY OF STATE
FUH. Calistus Gentry, PhD
09 March 2010
The REPUBLIC of CAMEROON lies midway
between West and Central Africa. It stretches
from the Gulf of Guinea in the South-West to
Lake Chad in the North and lies
approximately between 11° of (attitudes (01°
80f - 13° 00f N) and 08° longitude (08° 251 -
Yaounde, 2008 2
16°20f E). It is bounded to the:
■ South-West and West by the Gulf of Guinea
(the Atlantic Ocean) and the Federal Republic
of Nigeria respectively;
■ North by Lake Chad;
■ North-East and East by the Republics of
Chad and Central Africa respectively;
■ South by the Republics of Congo, Gabon
and Equatorial Guinea.
Cameroon's geological history begins with the Archaean era between 3.5 and 2.5 billion years (Ga) ago. Its different phases of development are illustrated by geological masses formed during successive orogenic cycles characterized by the formation of mountain ranges, and subsequent extension phases by the splitting of the continental crust.
Cameroon is generally acknowledged to have experienced three orogenic cycles:
1. The Liberian cycle, exemplified by the Ntemcomplex, which dates from the Archaean era, and is about 2.5 billion years old
2. The Eburnean or Transamazonian cycle, with the Nyongand Ayna, formations, which date from the Palaeoproterozoic period (2.5-1.8 billion years ago);
3. The Pan-African cycle, which comprises formations from the Neoproterozoicera 1,000-600 million years (Ma) ago.

The geology of Cameroonisdividedinto five geotectonicunits: (J. Vicat el al, 1998).
The Bélé-Libongo tillite complex, (850-650

sandstones, arkoses, conglomerates and
shale series of the lower Dja , and the
Lobeke numerous dolerites dykes and sills
occur with pillow lava and occasional
greater part of the territory and its
formations have been put in place during
the orogeny of the whole continent of Africa.
Its characterized by a strenching belt directed E-W from Sudan to Gulf of guinea and which extends into Brazil
territory. This chain (including two entities) : the christallophyllian and migmatitic formations formations of paraderived origin, and granitoïds which are either anatexic or syn and post - tectonic and most of them are calco-alkili), which belongs to the Oubanguides one, is cut by destral mylonitic shear zones trending NE-SW the Sanaga Fault (SF) and the CCSZ (Central Cameroon Shear Zone).
Due to this favourable environment for mineralization some principal project are under developpment and intensive exploration. They are:

202.5 million tonnes.
(2) December 9, 2009: Lycopodiumappointed to update feasibility
studies; deliverable date Q2 2010.
(3) December 16, 2009: Standard Chartered Bank engaged by Geovic MiningCorp as financialadvisor to the Nkamouna Cobalt Project.
Mine Permit: 1,250 km2
Nkamouna Proven & Probable Reserves:
54 million tonnes 0.25% cobalt, 0.69%
nickel and 1.33% manganese within a
mineralized area of 13 km2
Physical Concentration of this ore yields 12 million tonnes with upgrades to O.72% Co, 0.90 % Ni and 3.71 % Mn
Mada Inferred Resources:
145 million tonnes 0.21% Co, 0.48% Ni
and 1.15% Mn within a mineralized
area of 60 km2
Five other deposits contain 264 km2
of mineralized area
• 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.

Exploration campaign was conducted between January 16th and May 25th 2009. 11 plateaus on Minim-Martap and 3 plateaus on Ngaoundal were drilled, and 11,358 samples were collected, prepared, and analyzed.
Estimated Bauxite resources are around 550 Mt with potential for additional 100-200 Mt in the southern region of Minim-Martap deposit.
Alumina refinery, planned to be established near the bauxite deposits, will have the capacity of 3 Mtpa of smelter grade alumina (SGA).
It will be built in two phases.
Proven and robust technologies have been chosen in the process design, which is based on a typical low temperature digestion, given the gibbsitic nature of the bauxite.
Process and operating parameters will be in the first quartile of the industry. The plant will be operated to adhere to the best safety, environment, and efficiency standards in the industry.
