The Golden Triangle includes most of the major gold, silver and copper deposits in west-central Stikinia, a long-lived oceanic arc terrane that extends for about 1000 km along the length of the Canadian Cordillera. Most deposits are related to the Hazelton Group and affiliated intrusions (Latest Triassic to Middle Jurassic). More than 150 mines have operated in the region since prospectors first arrived near the end of the 19th century. Important past-producing mines include Granduc, Eskay Creek, Anyox, Kitsault, Premier/Dilworth, and Snip. Current mines include Brucejack (Pretium Resources Inc.), an epithermal gold-silver deposit that began commercial production in 2017, and Red Chris (Imperial Metals Corporation), a porphyry copper-gold deposit that began commercial production in 2015. The Golden Triangle contains numerous proposed mines and is being intensively explored. Enhanced infrastructure is encouraging exploration and development.
