Gold In Burundi
Gold Home
Burundi Mining Corporation (State) holds the mining title to most of the country’s primary gold occurrences, which are concentrated in Muyinga Province in northeastern Burundi.- Burundi Mining Corporation has been working on a gold project at Muyinga. Buminco, a joint venture between the government and private entrepreneurs, planned to begin small-scale mining in the Muyinga region, where there are 2 t of proven reserves.
- International Gold Exploration AB (Swedish, and also active in Kenya, Angola) is exploring the deposits in Mabayi-Butara, an area located in the north-western part of the country, about

Nickel

The Musongati Ni laterite deposit overlies the 1275 Ma (1.275 billion year old) Mesoproterozoic Mukanda-Buhoro-Musongati layered igneous complex. This complex is one of a number of ultrabasic complexes that were emplaced en-echelon within a 350 km long by 20 to 40 km-wide northeast trending corridor that extends from Burundi into Tanzania. Three nickel laterite deposits are known in Burundi: Musongati, Nyabikere and Waga. Within this corridor is the Kabanga nickel sulphide deposit in Tanzania. Although disseminated, nickel and copper sulphides have been described from rocks underlying the Musongati laterite, the Ni and Cu metal concentrations, found to date, are not significant economically. The Musongati laterites are derived from the weathering of the ultrabasic complex, particularly, serpentinised dunite with a primary nickel content of about 0.3%. Two types of ore are present in approximately equal proportions: limonite and saprolite. Nickel in the limonite ore type is tied to goethite whereas in the saprolite ore type it is related to serpentine group minerals (chrysotile, antigorite) and clay minerals (pimelite and nontronite). The typical weathering profile consists of lateritic soil, canga or cuirasse (iron caprock), limonite zone (averaging 15 m thick), saprolite zone (averaging 12 m thick) and ultrabasic bedrock.
- Argosy Minerals Inc (Australian, ) has title to the Musongati laterite Ni project situated in central Burundi, some 85 km east-southeast of Bujumbura. The indicated resource, based on previous exploration, is 28,659,000 t at grade of 1,62% Ni or 464,000 t nickel (0,8% Ni cut-off)
- Dwyka Diamonds Ltd (Australian) bought the Muremera nickel project in Burundi in an all-share transaction. The price tag on Muremera was a maximum $5m, with an upfront payment of $2m in Dwyka shares. The remaining $3m, also payable in shares is subject to project milestones. Dwyka subsequently announced that BHP Billiton will invest $5,2 million as exploration expenditure in the project, to earn up to 50% interest in Dwyka unit Danyland Ltd, which holds the exploration rights for nickel and associated minerals at Muremera. The Muremera target area is located within 2 km from the Xstrata/Barrick Kabanga Project in Tanzania, one of the largest known undeveloped nickel sulphide deposits in Africa. The second phase of the drilling at the Muremera Nickel Project in Burundi had started, the company said in January, 2008. Four drillholes had been completed on the Muremera B anomaly, which is considered prospective due to a superposition of both strong electromagnetic and magnetic anomalies. Up to 10,000 metres of drilling was expected in 2008.
