[2] The Red Lake Mining District has produced over 26 million ounces of gold through 2020, worth over $US 46 billion at 2020 prices.

The two principal mines, Campbell and Red Lake, both have historic ore grades averaging about 0.57 oz/ton Au (22 g/tonne).

The host rock here is a metamorphosed tholeiitic basalt dating to ~2.85 billion years (early Neoarchean).
