    The Equity Silver Mine is in British Columbia, Canada. The site was first discovered in 1967. The ore mined is composed of pyrrhotite, tetrahedrite and chalcopyrite with waste material consisting primarily of quartz, sericite and scorzalite. The host rock in this area is metasedimentary rock from the Upper Cretaceous epoch 100.50 to 66.00 million years ago.
