Open stopes will be backfilled with waste rock from the open pit hauled down the decline by empty ore trucks return from surface and mixed with cement underground. Barrick's Goldstrike Mine utilizes paste backfill, which is an alternative for Cortez in the future which may simplify the backfill process. Once the mine is in full operation it is ...
Mining at Round Mountain occurred as early as 1906, using underground techniques. The mine produced 350,000 ounces of gold through underground mining over a sixty-year period, before converting to an open pit.
