Deposit type

  • Metamorphic

Summary:

The nickel sulphide deposit at Trojan Mine occurs within a pile of ultramafic lavas subjected to a lower amphibolite grade of metamorphism and are characterised by lensoidal bodies of serpentinite. The lavas form part of the Upper Greenstones (Bulawayan Group) of the Mazowe greenstone belt. The serpentinite bodies are separated from each other by cherts, BIFs, graphitic shales and felsic volcanics. The footwall and hanging wall of the nickel bearing serpentinites are formed by komatiitic and tholeiitic basalts. A doleritic dyke cuts through the serpentinites and displays nickel sulphide along its sheared contact. The regional setting and deformation of the Harare-Bindura schist belt with thrusting and doming of the Chinamora batholith has given rise to the deformation imprint observed in host rocks at the mine. The general strike of the ore bodies is east–west and dip steeply (75° to 85°) to the north and this is controlled by the regional foliation trend. The two major ore bodies are the Main Orebody and the Hanging Wall Orebody. The massive and near massive ores occupy a narrow and discontinuous zone along the footwall of the Main Orebody and this is called the Footwall Massive Orebody. The Main Orebody is the largest, and averages 250m long and 30m wide. There are other smaller ore bodies such as Trojan Hill, Cardiff East and Cardiff Far East, with dimensions of 100m x 15m and 200m x 15m respectively. Drilling has outlined the Main Orebody to a depth of 1180m below surface. Approximately 300m of longhole drilling is still planned to increase the confidence in the geometry of the Main Orebody at depth, and reduce the variation on estimation of grade, for the current shaft deepening programme.

Three types of nickel sulphide ore are found at Trojan Mine, namely: massive ore, near massive ore and disseminated ore, whose main sulphide minerals are pyrrhotite, pentlandite and chalcopyrite, with pyrrhotite being the most abundant. Minor amount of millerite and pyrite are also present. The massive and near massive ores are situated towards the base of the ultramafic units and are overlain by the disseminated ore. The main and hanging wall orebodies contain all three types of mineralisation.
