| Location and accuracy | This prospect is known only from U.S. Bureau of Mines (1977) claim records. Its approximate location is at an elevation of about 2000 feet, about 0.1 mile north of Adanac Creek. The site is in section 12, T. 68 S., R. 99 E., of the Copper River Meridian. It corresponds to loc. 7 in Elliott and others (1978). The location is accurate within 0.5 mile. |
Geologic descriptionThe country rocks in the area of this site are Jurassic or Triassic Hazelton Group metagraywacke, slate, and greenstone that are intruded by apophyses of the Eocene Hyder Quartz Monzonite batholith (Buddington, 1929 [B 807]; Smith, 1977). U.S. Bureau of Mines claim records (1977) do not specify the commodity for which this prospect was staked. Its geologic setting, and proximity to other mineral deposits in the Hyder district, however, suggest that they probably include some combination of Cu, Pb, Zn, or Au. No other information about this prospect has been made public. | |
