Where to Find Sphalerite in Utah

Utah sphalerite is the zinc counterpart to the galena that drove the state's lead-silver districts. Tintic sphalerite from Eureka and Mammoth is often dark brown to black, with cleavable masses in dolomite alongside galena and pyrite. Park City–Ontario carries lighter honey-brown sphalerite in vugs of dolomite breccia, and the San Francisco district at Frisco adds resin-amber crystals on quartz. Smaller occurrences in the Gold Hill district produce green-tinted sphalerite from the lead-zinc-arsenic ore bodies. Surface dump material is usually weathered to smithsonite or hemimorphite; fresh sphalerite needs underground or deep-dump access.
