Buhemba & North Mara Gold

Gold mineralization at Buhemba has been assessed through surface and selective underground geochemical sampling across former colonial mining. The area is very promising, with potential for underground mining via the old Main Shaft.

Two main zones are oriented NNW with pinching and swells between 1–2 m wide; shear zones trend 450–500° with visual veining systems. Recent samples assayed up to 36.8 g/t (SGS assays). The mine is estimated to contain about 747,000 ounces of gold at 3.35 g/t.

Major rock units are quartz vein, feldspar-porphyry and carbonate-altered mafic volcanics/metamorphosed basalt, metasediments, dolerite and quartz-eye porphyry. Recent exploration produced 2.4/3.0 m, 12.2/3.0 m and 42.0/1 m gold intercepts.

Mineralization occurs close to sheared and carbonated rocks of both felsic and mafic origin and the Banded Iron Formations, in quartz veins dipping at shallow angle, with reef thickness of 0.5–3 m.

Located 50 km south-east of Tarime town. Exploration completed includes detailed and reconnaissance mapping, trenching, auguring/pitting, grab sampling and magnetic survey.

Highlights: within the North Mara gold province, close and on strike with Barrick Gold's 280,000 oz Nyabirama; within one of the largest known developed gold deposits in Tanzania (~6 million ounces). Recent work returned encouraging grades up to 28.1 g/t.
