We collected excellent crystals of tetrahedrite to 5 mm scattered on drusy quartz from a zone in the siliceous envelope of the orebody.
The district also produced many other mineral species in attractive specimens, including honey-golden barite, fluorapatite, gold, polybasite, rhodochrosite, and tetrahedrite .
The ore shoot is mainly in the Molas Formation and is surrounded by a silicified envelope that contains galena, sphalerite, chalcopyrite, tetrahedrite , and pyrite.
Copper-silver ore, located in the cores of the chimneys, consists primarily of chalcopyrite, tetrahedrite , pyrite, and galena along with electrum and a number of minor silver minerals.
Hurst observed pyrargyrite partly and completely enclosing polybasite crystals on tetrahedrite .
