Chiwala
Immediately south of historic tin workings, with 98 satellite-identified pegmatite targets including one 220 m in length.
The Chiwala Project covers an area of 1,480 hectares and lies immediately south of historic tin workings, mined since the 1930s. Sable Ridge Metals holds 100% of the licence.
Satellite (ASTER) analysis has identified 98 pegmatite targets across the tenement, ranked by prospectivity: 30 rank-1, 34 rank-2 and 34 rank-3 targets. Interpretation indicates pegmatite occurrences to the west of the tenement, including a single target some 220 m in length.
Recent sampling has returned up to 1.3% SnO₂. Further exploration work is planned to test the ASTER targets within this under-explored area.

Why pegmatites carry so much
LCT (lithium–caesium–tantalum) pegmatites are the last, most chemically evolved fraction of a granite melt. As the magma cools, the elements that don't fit ordinary minerals — lithium, tin, tantalum, niobium — concentrate into these coarse-grained dykes.
In the Mwenda Belt the dykes intrude a metamorphic gneiss basement and weather out at surface, which is why artisanal miners have been able to work them by hand since the 1930s — and why modern sampling can test grade without drilling first.
