Between 1988 and 2001, the gold that was produced at Fosterville Gold Mine was extracted via a heap leach operation. A remanent heap leach stack remains within the current CIL (Cabon in Leach) precinct of the Fosterville Gold Mine.
In September, Fosterville commenced a significant project to rehabilitate the remnant Fosterville heap leach stack. The heap is being reshaped to achieve a 1 in 3 gradient, and the excavated material is being used to cover the CIL hardstands, which have reached their operational capacity. Upon completion of earthworks, the area will be sprayed with a hydroseeding mix to establish vegetation cover.
The recontouring and rehabilitation of the remnant heap leach stack will assist with erosion and sediment control, improve surface water management, and enhance visual amenity of the landform. Fosterville currently has a fleet of excavators, bulldozers, and dump trucks operating within the area, with earthworks scheduled to be completed by the end of the year.
