Buzwagi is a shear-hosted quartz-veined deposit, hosted in porphyritic granite.
Life and reserves
Life-of-mine is currently estimated to be around 10+ years, based on its proven and probable gold reserves of 2,697,000 ounces.
The Buzwagi mine is located in northwest Tanzania in the Kahama district of the Shinyanga region, approximately 97 km from Bulyanhulu and 6 km southeast from the town of Kahama.
The mill is designed with a throughput capacity of 12,000 tonnes of ore per day (c. 4.4 million tonnes per year) and produces both doré and copper/gold concentrate.
Buzwagi is well connected. The site lies immediately beside a paved highway and a 1,580-metre airstrip. It is also only 40 km from Isaka, a railway hub with links to the port of Dar es Salaam on the Indian Ocean.
The annual average temperature ranges from 16° – 29°C. Average annual rainfall in the region is 953mm.
The Buzwagi mine is a low grade bulk deposit with a single large open pit.
