Gold in Uke occurs as primary ore deposits within quartz and quartz-felspathic veins, which are hosted in the biotite-gneiss suits of the rocks of the Basement Complex. It is estimated that about 20–30 troy oz (0.62 to 0.93 kg) of gold are recovered daily through artisanal gold mining operations.
The Uke artisanal gold mining region provides a direct source of livelihoods to about 4000 miners at the mines and processing centres. The working conditions at the mines and processing areas were found to be extremely poor and with equipment spread all over the ground. The mining method is underground, reaching a depth of 20 m and operated by six miners per group that blast, muck the ore, and pull buckets to the surface. There are 60 miners from different groups working underground in a specific mineralized zone. The ore is carried manually to a truck that transports it to the processing area 4 km away. The mining operation involves seven days of blasting, mucking, hauling, and transporting the ore to the surface and to processing plants by truck. The typical load of ore in a truck is 6 tonnes per a shift of one week. Another week is used by the group of miners to process the ore. In total, it takes about two weeks to have the gold in the miners’ hands.
