Buzwagi is an open-pit mining operation and the smallest of Acacia Mining`s three gold producing mines. Commercial production commenced in 2009 and in 2013, mine life was shortened following a decision to suspend a final cut-back of the open pit. In 2018, the mine produced 145koz of gold. Concentrate production ceased in 2017 following the Tanzania concentrate export ban. Based on year-end 2018 reserve estimates, stockpile processing is expected to continue until 2021, solely producing gold dore from the gravity and CIL circuit. Development of a closure plan is on-going with various closure options under consideration.
