Executive Summary
The DDGM Processing Facility processes ore from the Arista and Switchback underground mines through a flotation circuit. The facility includes a sequential flotation (sulfide) circuit and an agitated cyanide leach (oxide) circuit. In 2023, the plant processed 458,111 metric tonnes of ore, yielding significant quantities of gold, silver, copper, lead, and zinc. Mining operations utilize underground methods including cut and fill and long-hole open stoping, with paste fill backfilling implemented since 2019.
The processing plant produces three separate saleable concentrate products (gold-copper, silver-lead, and zinc) from polymetallic ore. A gravity concentrator using Knelson technology enhances separation based on particle density. In 2022, a new flotation circuit was installed to recover remaining sulphur associated with gold, which is then leached in the agitated cyanide circuit. Doré is sold to refiners such as Asahi Refining USA, Inc.
