Abstract In 1992, the Ford gold deposit was rediscovered during field work in the Kwekwe district near the Indarama mine, approximately 200 km southwest of Harare, Zimbabwe. Based on diamond drilling and open pit operations, estimated ore reserves are at least 3 Mt with an average gold content of 2.5 g/t. The gold deposit is located within …
he world-class Meso-Neoarchaean Bikita pegmatites which host Li, Cs, Ta, Be and Sn mineralisation are enclosed by the elongate shaped Masvingo Greenstone Belt which is situated within the southern part of the Zimbabwe Craton. There are 15 denoted pegmatites within the Bikita mining lease and from these the main pegmatite is the most extensively …
