Red Lake is an underground gold mine in northwestern Ontario, Canada. The operation comprises the Red Lake, Campbell and Cochenour mines over a strike length of 7km. The Cochenour mine is connected to Red Lake by a 5km haulage drift, with ore processed at the Campbell Mill.
Red Lake is accessible by major highways, with commercial air services to the mine from Thunder Bay and Winnipeg. Red Lake is supported by an experienced and highly-skilled workforce largely residing in adjacent towns of Red Lake and Balmertown and benefits from strong community partnerships with Lac Seul and Wabauskang First Nation Groups.
Mining at Red Lake is undertaken predominantly via long-hole stoping. Processing at the Campbell mill is via conventional crushing and grinding followed by gravity concentration to recover free-milling gold, with refractory gold recovered by floatation followed by pressure oxidation, neutralisation and CIL.
