Location: The Juneau occurrence is in Section 26 at an elevation of about 3800 feet on a west-facing mountainside above Ferguson Glacier (Elliott and Koch, 1981, p. 13, loc. 40). The location is probably accurate within about a quarter of a mile.
Geology: The country rocks in the area of the Juneau occurrence are pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group, which are underlain and locally intruded by the Triassic Texas Creek Granodiorite (Smith, 1977; Koch, 1996). Buddington (1929, p. 108-108) describes the deposit as a quartz vein 3-6 feet thick in Texas Creek Granodiorite. The vein, reportedly traced on the surface for 1300 feet, locally contains small shoots of chalcopyrite. A second vein is said to carry galena and pyrite.
