Hope Brook operated using both heap leach (1987 -1990) and conventional cyanidation milling methods (1989-1997) with a later inclusion of flotation concentration to recover copper (1991).

A 100 tonne per day processing plant with a vat-leach cyanidation and Merrill Crowe circuit was in operation in 1989-1990. The basic infrastructure is sound, but some equipment will need replacement.
