North Mara production is expected to be a combination of high-grade underground material from Gokona underground and open pit material from the Nyabirama pit for five years.
The underground project is expected to produce 450,000oz over its planned five years in operation, with possible lateral extensions and mineralisation remaining open under 300m vertical depth cut-off.
Acacia Mining CEO Brad Gordon said: This project is reflective of our new approach to operating our assets whereby we have re-engineered the mine to drive free cashflow and at the same time have significantly reduced the mine’s footprint, which helps our relationships with the communities around the mine.
According to Acacia, Nyabirama pit and Gokona underground operations will enable the company to produce of more than 250,000oz of gold a year from North Mara mine.
