This sample is part of the Hudson Bay Mountain (Omineca district) complex, which is a large, porphyry-Mo system that extends laterally for approximately 3 km, and which is then enveloped in a polymetallic vein system that extends outward for approximately 8 km. As such, the overall system is classified as a Porphyry-Mo system for classification purposes. The specific mines from Hudson Bay Mountain in the Allard Collection include Duthie, Empire, Victory, Henderson, and Last Chance.
