TSX-listed Tanzanian Gold Corporation recently announced that 90% gold recovery has been attained on a consistent basis at the oxide test plant at its Buckreef gold project in Tanzania.
The focus of the oxide test plant was on recovery rates utilizing similar retention time and grind size design parameters as the 15 tph and +40 tph expansions. The results of the gold recovery tests are above the gold recovery rates previously achieved at the oxide test plant, when the goal was to maximise gold production versus maximising gold recovery rates.
These higher gold recovery rates provide increased confidence in an already robust oxide mine plan. Higher gold recoveries increase revenue per tonne and lower costs per gold ounce versus lower gold recovery rates.
“The results of the focused oxide test plant aimed at maximizing recovery of the oxide mill feed have conclusively demonstrated 90% gold recoveries. I am delighted with the results and look forward to the finalization and commissioning of the 15 tph operation,” noted Stephen Mullowney, CEO.
The Buckreef project is located in north-central Tanzania and comprises the dormant Buckreef gold mine and four prospects with known mineralisation: Buckreef, Buziba, Tembo and Bingwa. Tanzanian Gold Corporation along with its joint venture partner, STAMICO is building a significant gold project that is based on an expanded mineral resource base and the treatment of its mineable mineral reserves in two standalone plants.
Measured mineral resource now stands at 19.98 Mt at 1.99 g/t Au containing 1,2 Moz of gold and indicated mineral resource now stands at 15.89 Mt at 1.48g/t Au containing 755 000 oz of gold for a combined tonnage of 35.88 Mt at 1.77g/t Au containing 2 Moz of gold.
The Buckreef project also contains an inferred mineral resource of 17.8MT at 1.11g/t Au for contained gold of 635 000 oz of gold. The company is actively investigating and assessing multiple exploration targets on its property.
