on ore resource and reserve estimation. Nevertheless, it is surprising how little attention is paid to density variations at some mine sites. The most efficient form of density measuremen. t is gamma-gamma logging. However, downhole density logging is rarely conducted in metalliferous mines other than iron ore mines,.
