Ring-shape and linear gold mining districts of zimbabwe: estimation of residual gold resources

open access: yesИзвестия высших учебных заведений: Геология и разведка
Background. Despite the long history of exploitation and study of Zimbabwe’s geological potential, the ranks of gold ore formations at the level of regions and fields remain unclear. Assessment of the residual primary gold deposits in Zimbabwe appears an
