Circum-Superior Belt mantle plume that was the source for the 1,880 million-year-old magmatism in the Circum-Superior Belt. The Circum-Superior Belt is the host for widespread mineral deposits, including copper, nickel and platinum group elements. However, the origins of this widespread mineralization is unknown.

Since its foundation during the 1950s, numerous mining operations throughout the Thompson Belt have produced over four billion
