Mining methods and key infrastructure

Several open pits have been developed along the strike extent of the ore body, named from north to south: Boston Shaker, Tropicana, Havana and Havana South. Underground mines are also in operation beneath the Boston Shaker and Tropicana open pits with a Mineral Reserve declared for the Havana underground.

The processing plant has a capacity of 9.4Mtpa. The crushing circuit consists of a primary gyratory crusher, feeding a set of secondary cone crushers and a tertiary high-pressure grinding roll. A 14MW and 6MW ball mill in parallel completes the grinding circuit. A CIL circuit is used to extract the gold from the ore, and a standard AARL elution and recovery systems are used to produce gold doré bars.
