Natural Resources. Currently there are at least 52 types of mineral resources each constituting a mineral target have been discovered, each constituting a mineral occurrence. These mineral targets have been studied from the geochemical anomaly right to the deposit.


Minim-Martap Deposit The bauxite deposit of Minim-Martap occurs on a barren plateau separated by shallow valleys. The slopes around the Minim-Martap plateaus are gentle and allow a reasonably easy access to the bauxite. The Minim-Martap bauxite deposit form a signiicant part of the Adamawa plateau. They occur as a circle shaped cluster of plateaus covering about 1000 km centered at 06 Minim-Martap can be accessed from Ngaoundal by the Ngaoundal-Tibati paved road (N-6) and from Ngaoundere by the road (D-19) to Tibati that passes through the northern part of the permit area. The distance between Minim and Ngaoundere is approximately 73 km (aerial). A secondary road (N-15A) follows the eastern limit of the bauxite deposit. This road connects Martap to Tekel, Beka-Gotto and inally Sebadi on the paved road (N-6) between Ngaoundal-Tibati. Ngaoundal Deposit The Ngaoundal bauxite deposit forms a high, isolated and dissected plateau the Djerem plain Ther e is a fairly steep escarpment surrounding most of the deposit, but there are also ridges which run down to the plain and do wn. The deposits of Ngaoundal are on the plateaus which are elevated about 300m above the surrounding valley side.


At least 140 targets mostly found within the boundaries of a vast corridor which includes the Western part of Central African Republic (RCA), the Southern part of Chad, the Eastern part of Eastern part of east Cameroon, the Adamawa region and the part of the north and far North regions. There is a cross-border continuity between the gold bearing targets of Cameroon, the CAR and Chad as well as an identity of the geological context.


Titanium: more than 65 targets where discovered. Most of the targets expressed in the form of rutile and associated to disthene and garnet, are found in the vast paraderivative ditch of the Yaounde group, extended towards the NW over more than 50,000km2. Cameroon used to be the third world rutile producer after Australia and the United States. Recent studies indicate a 3 million ton of alluvial titanium reserves for the Akonolinga area, in the average watercourses, tributaries and main sewers. Good concentrations expressed in the form of titaniferous iron ore are found in seacoast sands with a non exhaustive evaluation giving 500,000 tons of titaniferous iron ore. So, rutile reserves in Cameroon are the 2nd world reserve after Sierra Leone.


17 targets 9 of which are found in the vast gold bearing corridor are currently exploited by the craft industry in the border zone with the CAR, then several occurrences in the series of lower Dja including a deposit (Mobilong) made up of 26 small scale mining sites. From Touboro to the Far South of the country, signiicant diamond occurrences were found along the 700km border with CAR which produces between 400,000 and 800,000 carats of diamond per annum.


At least ive good sapphire targets were discovered in the sedimentary series of the gulf of Mamfe, in the Munaya and Nsanasakati watercourses. Research work gave a minimum guarantee of 830g of sapphire for 2,107g of gem, found in the Nsanarakati sector. Sapphire was recently discovered in the Adamawa region and is currently exploited mainly by small scale miners in 4 of the 5 divisions of the region.


5 shows at least are found in the Lom series around Betare Oya, in Yingui in the North – East of Douala, and Far North around Mayo Moue and Mayo Boula.


There are 3 coastal sedimentary oil-bearing basins: Rio del Rey, Douala and Kribi – Campo. Since 1997/98, oil is also mined in the Douala/Kribi – Campo (Ebome Marine) basins though it is a modest production (10 000 barrels/day). A positive oil well was already dug by PHILIPS in the Douala basin. Other sedimentary intercontinental basins possibly contain hydrocarbon: Mamfe, Garoua and Logone Birni basins in the Far North. The last basin shares boundary with the Doba basin in Chad. Oil transported by Pipe line through Cameroon is low: approximately 100,000 barrels per day. The Republic of Cameroon, lies on the eastern border of oil-rich Nigeria, and is the sixth largest oil producer in SubSaharan Africa with oil reserves estimated at 400 million barrels in January 2004. The country has gas reserves, estimated at 110 billion cubic metres (bcm), that are still unexploited. The upstream oil industry is an important part of Cameroon’s economy.


About fifty uranium targets have been discovered. Most of them, in the form of geochemical anomalies were detected by systematic mining inventory in the south of the 4th parallel.


Approximately 25 iron targets and deposits have been discovered among which the Mamelles deposits in the South of Kribi with 330 MT, 30% of iron: the Mbalam deposit in the South of Ngoila with reserves worth 807 MT of which 220MT makes up more than 60% of iron and 587 MT made up of 22-38% of Iron ore.


6 occurences and deposits among which colbato nickeliferous laterite on serpentinite deposits are found in the North East of Lomie in the locality of Kongo, North and South of Mang. These deposits cover 240m2, but an attempt to evaluate with boring over a surface area of 8.5km2 in Kongo revealed 200.000 tons of cobalt metal accompanied by an appreciable tonnage of Nickel and Manganese for this small area. The company GEOVIC – Cameroon has obtained a mining permit over this area. Two other occurrences have been revealed in Ngoila and Mbalam


Beyond the Nickel deposit associated with laterite Cobalt on serpentinites; other 27 Nickel occurrences were discovered in relation to the iron-bearing furrows, with intrusions of ultra basic rocks, contact basement of schistoquartzitic series, or with the same schistoquartzitic series, recognized as sedimentary volcanoes.


17 occurences were revealed among which the Mayo Darle deposit of which alluvia and eluvium are subject to an outdated small-scale mining with 6500 tons of cassiterite extracted from 1933 to 1968. The potential of this deposit is still to be deined. These occurrences are in connection with the young intrusive granites, the microclinized and gratinized base the iron-bearing furrows.
