In a bid to identify features useful in discriminating barren from gold-bearing veins and thus assist in the training of locals on site suitability selection for shallow-depth gold exploitation from weathered veins, we investigated a major vein set in the Batouri gold district of eastern Cameroon hereafter referred to as the Mama vein system. The mineralized veins trend NE-SW and are foliated with sericitic, carbonate, sulphides and hematitic alterations. Quartz in the mineralized veins is brecciated, fibrous and smoky. Gold grains occur as inclusions in hematite mainly derived from the weathering of sulphides. Thus brecciated to stock work hematite-bearing veins in prospective mining sites is the main target for the local miners since they are the main host of primary mineralization in Batouri. The gold grains are rich in Ag and show low gold fineness (maximum 615). Bulk geochemistry reveals Au-As-Hg-Zn-Pb-Sb-Mo element association indicative of a low sulphidation environment. Fluid inclusion data affirm to moderate salinity brine as the ore-bearing fluids and mesothermal conditions of ore deposition consistent with the magmatic source of gold. The δ34S values for this system reflect a single homogenous and general light source for sulfur.
