Location: The Bishop prospect is on the west shoulder of Skookum Creek at about 1300 feet elevation. The site is in section 11, T. 68 S., R. 99 E., of the Copper River Meridian. It corresponds to loc. 3 on plate 2 in Buddington (1929 [B 807]), and to loc. 5 in Elliott and others (1978). The location is accurate within 0.1 mile.
Geology: The country rocks in the area of this site include: pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or Triassic Hazelton Group; recrystallized granodiorite of the Triassic Texas Creek Granodiorite, which intrudes the Hazelton rocks; quartz monzonite and granodiorite of the Hyder Quartz Monzonite batholith, which intrudes the Hazelton and Texas Creek rocks; and Tertiary lamprophyre dikes, which intrude all of the foregoing rock units (Buddington, 1929; Smith, 1973, l977; Berg and others, 1988). The deposit consists of a sulfide-bearing quartz fissure vein in (Texas Creek) granodiorite (Buddington, 1929, p. 67). The vein ranges in thickness from about 15 inches to 7 feet and was traced on the surface for 600 feet. It contains pyrrhotite and pyrite, a little chalcopyrite and galena, and traces of gold and silver. The vein was explored in the early 1900s by a 10-foot adit. Maas and others (1995, p. 254) suggest that sulfide-bearing quartz fissure veins in the Texas Creek Granodiorite in the Hyder district are Eocene in age.

Age: Maas and others (1995, p. 254) suggest that sulfide-bearing quartz fissure veins in Texas Creek granodiorite in the Hyder district are Eocene in age.
