Strandline Resources has reported mineralisation over large areas with significant sand thicknesses at its 100% Tajiri mineral sands prospect in northern Tanzania. Initial assay results show grades of 5-16% total heavy mineral. Some 160 air core holes were drilled at the prospect. Further drilling is expected to link two resource domains. The work could be defining a new mineral occurrence. Mount Burgess Mining has reported that gallium and germanium occur in the upper oxidised portion of its Kihabe-Nxuu base metal prospects in Botswana. The deposits are unexpectedly low grade, with just 3% combined lead and zinc, given that the primary mineral is a zinc-rich carbonate species. By product credit are unlikely to materially change the development economics. Broken Hill regional explorer Silver City Minerals is planning a drilling program at its historic Stephens Trig prospect in coming weeks. The program is designed to test the potential of shallow base metal sulphide strike extensions. A potential shallow pit would target ore for available mineral processing facilities in Broken Hill allowing for a rapid advancement to production.
