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 (22 g/tonne).[2]

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 (early Neoarchean). This basalt has been subjected to biotite-carbonate alteration and auriferous silicification. Gold mineralization has been dated to 2.712-2.723 billion years (during collision-related emplacement of several nearby igneous intrusions - Uchian Phase of the Kenoran Orogeny), and at 2.63-2.66 or 2.699 billion years (during a regional thermal event or another igneous intrusive event).[3]

On November 25, 2019, Newmont Goldcorp announced an agreement to sell the Red Lake complex to Evolution Mining.[4]
