Geology
The geology of Zimbabwe is dominated by Archean rocks which are overlain, in the northwest, by Proterozoic and Phanerozoic metamorphic and sedimentary rocks, in the area of the Project. In this area, phyllites, quartzites and gneisses are the dominant rocks.
The host country-rock comprises high-grade, strongly foliated biotite schists and paragneisses of the Tshontanda Formation belonging to the Precambrian Dete Inlier. The formation trends northeast on a regional scale, paralleling the trend of the Kamativi Inlier, and dips steeply to the northwest.
Mineralisation
RHA mine is situated within the multi-commodity Kamativi Tin Belt and occupies a land holding on a low ridge of approximately 850 m long and 300 m wide standing about 120 m above its surroundings. Historic mine workings are present and are in the form of adits, open pits, caved stopes, trenches, roads, and rock dumps that occupy the surface.
From information received from PAM it was noted that the known mineralised lodes and veins occur within an envelope that extends over a strike of approximately 400 m with a maximum width of 150 m. The lodes are thought to converge to the east of the property. The lodes strike approximately northeast-southwest paralleling the regional trend of Kamativi Inlier.
The host country-rock comprises high-grade, strongly foliated biotite schist’s and paragneisses of the Precambrian Dete Inlier belonging to the Tshontada Format ........
