The Barrick Goldstrike Mine
Waste Rock Management
Goldstrike, the largest gold mine in North America, includes the Bazza waste rock facility. At closure there Bazza will contain nearly 2 billion tons of rock covering 2,400 acres at closure. Schafer helped develop waste rock management procedures at Goldstrike including development of criteria for identifying and selectively handling PAG waste rock. The Waste Rock Management Plan incorporated alternative waste rock placement in the North Block Tailings embankment and as backfill in the open pit.
