Where to Find Chalcopyrite in Utah
Chalcopyrite is the primary copper sulfide in Utah's porphyry and skarn districts. Bingham Canyon in Salt Lake County is the largest producer, although the active pit is closed and most collecting is from old peripheral dumps and the West Mountain pits. The Tintic district yields chalcopyrite with pyrite, galena, and sphalerite in dolomite vugs at Mammoth and Eureka. San Juan County's Cane Creek and Lisbon Valley anticlines produce chalcopyrite in sandstone alongside chalcocite and bornite. Surface chalcopyrite tarnishes to a peacock-iridescent film, so look for fresh fracture surfaces with a clean brassy-yellow color.
