The Greenstone Mine commenced production in May 2024 and will be one of Canada's largest open-pit gold mines, with annual production expected to average nearly 400,000 ounces of gold per year for an initial 14-year mine life with additional potential from a large underground deposit. Greenstone Gold Mines LP is owned by Equinox Gold Corp, a Vancouver-based mining company with five operating mines in Canada, the United States, Mexico and Nicaragua.
