Buzwagi is a shear-hosted quartz-veined deposit, hosted in porphyritic granite.
Life and reserves
The Life-of-mine has recently been updated in response to the changed gold price environment and has reduced to 6 and a half years with life of mine production of approximately 1.1 Moz. This means that the remaining reserves will be reclassified to resources in the next reserve update.
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.
