Gold developer Theta Gold Mines on Tuesday told shareholders that a plant optimisation study at its namesake project, in South Africa, has found that the throughput capacity at the plant could increase from the originally anticipated 500 000 t/y to 600 000 t/y at minimal costs.
Theta noted that the 20% increase in the new plant design would be achieved with less than a 1% change to the processing plant capital of $24.85-million, estimated in the feasibility study.
