Twangiza is the most advanced of Banro's four properties with a Mineral Reserve of 22.98 million tonnes grading 2.28g/t Au containing 1.64 million ounces of gold.
The Twangiza deposit is comprised of two resource components - an oxide portion and a transition rock/fresh rock (non-oxide) portion. The current activities involve mining and processing a blend of both oxide and non-oxide material within the reserve pit shell using the existing plant. Exploration activities are focused on growing the oxide resource. This Mineral Resource consists of a Measured & Indicated Resource of 109.28 million tonnes grading 1.50 g/t Au containing 5.26 million ounces of gold and an Inferred Resource of 12.99 million tonnes grading 1.15g/t Au containing 0.48 million ounces of gold.
