Bissa East
The Bissa East Project comprises two contiguous Exploration Permits, Tangapella and Biliga, which lie 100 km northeast of the capital city of Ouagadougou. Both are wholly owned.To date, the company has defined three gold zones on Tangapella and two on Biliga, which have been mapped, sampled and drilled, and another 28 gold anomalies await further work.
The Bissa East permits collectively cover an area of 498 square km, and were acquired to cover portions of the northeast trending Sabcé shear zone. The Sabcé shear zone hosts a large number of known gold deposits over a distance of approximately 130 km, the largest of which is the Bissa Hill deposit, held by High River Gold Mines. High River announced a 43-101 compliant mineral resource estimate for Bissa Hill of 2.3 Moz gold and the mine is currently under construction. The Tangapella permit boundary is 6 km from the Bissa Hill deposit.
Since acquiring these properties, Riverstone has completed soil geochemistry, geological mapping and rock sampling on all three permits. A large number of artisanal gold mining sites have been mapped within the project area which covers a 30 km strike length of the Sabcé shear zone. This includes channel sampling, and a total of 6,785 metres of RAB (Rotary Air Blast) and 1,884 metres of RC (Reverse Circulation) drilling. The best intercepts from these programs are tabulated below:
