Manitoba has ranked in the top 20 of the Fraser Institute’s annual list of the most attractive mining jurisdictions for 21 of the last 23 years, and has an exceptional mineral profile across an entire suite of metals—from copper, nickel, zinc and gold to diamonds, graphite and strategic minerals. Eighteen of the 31 minerals that Canada placed on its new list of critical minerals released at the PDAC Convention in March are either being explored for or are being produced in the province.
