Geologic information

Identification information

Deposit ID 10000183
MRDS ID A010222
Record type Site
Current site name Gold Cliff Premier

Geographic coordinates

Geographic coordinates: -130.04564, 56.05283 (WGS84)
Relative position The Gold Cliff Premier prospect is at an elevation of about 450-800 feet adjoining the Salmon River at the northeast foot of Mineral Hill (Elliott and Koch, 1981, p. 16, loc. 60). The original claims lay along both sides of the river, and the property appears to straddle the boundary of sections 23 and 24. The location is probably accurate within a quarter of a mile.

Comments on the geologic information

  • Geologic Description = The country rocks in the area of the prospect are pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Texas Creek Granodiorite, which underlies and locally intrudes the Hazelton; the Eocene Boundary Granodiorite, which intrudes the Hazelton and Texas Creek rocks; and still-younger Tertiary lamprophyre dikes that cut all of these rocks (Smith 1973, 1977; Koch, 1996).? the deposit (Buddington, 1929, p. 90) is in quartzite, tuff and slate cut by Triassic and Eocene porphyritic granodiorite dikes and consists of intensely fractured and pyritized quartzite, and of sheared tuffaceous rock mineralized with a 2.5 foot band of pyrite, quartz, and calcite. Samples of the mineralized band assayed as much as 1 oz Au and 3-4 oz Ag per ton. Elsewhere on the property, there is a narrow stringer of galena, and a 1-inch stringer of sphalerite, chalcopyrite, tetrahedrite, and pyrrhotite.
