Acacia  has resolved the previously disclosed issue of the overheating of the ball mill trunion bearing at Bulyanhulu and the process plant is now operating at normal throughput levels. 

The overheating was found to be due to flex in the trunion footplate which led to increased friction on the bearing. The issue has been resolved by stabilising and reinforcing the base of the footplate. 

Further work will be carried out during a planned plant shutdown in Q4 2016 with a full bearing housing replacement to be installed during 2017 to provide a life of mine solution.

The group says: "As a result of the resumption of stable operation of the process plant and delivery of paste fill, we have recommenced stoping in the underground mine and our full year production guidance for Bulyanhulu remains unchanged. 

"Furthermore, at a group level we continue to expect Q3 2016 production to be broadly in line with Q1 2016, with unchanged full year production guidance of at least 780,000 ounces of gold."
