Red Lake Mine
The Red Lake mine is one of the largest gold mines in Canada and in the world. The mine is located in northwestern Ontario at Red Lake. The mine has estimated reserves of 3.23 million oz of gold.
The Red Lake Mining District has produced over 22 million ounces of gold through 2004, worth over $US 35 billion at 2014 prices. The two principal mines, Campbell and Red Lake, both have historic ore grades averaging about 0.57 oz/ton Au.
The rocks and mineralization features in this district are complex. The host rock here is a metamorphosed tholeiitic basalt dating to ~2.85 billion years. This basalt has been subjected to biotite-carbonate alteration and auriferous silicification. Gold mineralization has been dated to 2.712-2.723 billion years, and at 2.63-2.66 or 2.699 billion years.
On November 25, 2019, Newmont Goldcorp announced an agreement to sell the Red Lake complex to Evolution Mining Limited.
