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).<ref>[http://www.grandviewgold.com/Gold_Properties/Red_Lake_Gold_District/?sp=Mineralization Red Lake Gold District]</ref> One famous sample, the "Campbell Mine Whopper", contained 431 ounces of gold in a football-sized rock.<ref name=gfe>[https://www.geologyforinvestors.com/red-lake-the-times-they-are-a-changin/ Red Lake gold district] at Geology for Investors, May 30, 2022</ref>
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).<ref>[https://www.flickr.com/photos/jsjgeology/14550435790/in/set-72157645487505837/ Red Lake gold mine]</ref>
