Northern Star internal contractor Northern Star Mining Services (NSMS) has delivered the highest ore recovery in the life of the Kalgoorlie gold operations within two months of installing Minnovare’s drill and blast technology.

The operation achieved 100 additional drill metres per day, resulting in around 3.5 per cent reduction in stope turnover time.

This improvement brings around 5000 additional ounces and $8.4 million additional revenue at the current gold price when rated over a 12-month period.
