Bulyanhulu is located in northwest Tanzania, in the Kahama district of the Shinyanga region, approximately 55 km south of Lake Victoria and 150 km southwest of the city of Mwanza. Byrnecut Offshore Tanzania Ltd was awarded the development contract at Bulyanhulu in February 2014. Byrnecut’s scope of works included decline and lateral development and haulage.
Byrnecut managed all fleet maintenance. The Bulyanhulu process plant has the capacity to process an average of 3,300 tonnes of ore per day, and produces both doré and copper/gold concentrate. The mine is an underground trackless operation using long-hole stoping as its principal stoping method.
Byrnecut improved development advance rates in strategic project areas by introducing proven mechanised mining and maintenance procedures whilst ensuring smooth integration of expatriate and Tanzanian workforces.
In September 2017, Acacia decided to move to a reduced operational state at the mine due to the deterioration in the operating environment.
