Identification information

Deposit ID 10307661
Record type Site
Current site name Ace

Geographic coordinates

Geographic coordinates: -131.15775, 55.21775 (WGS84)
Relative position This prospect is known only from U.S. Bureau of Mines (1977) claim records. Its approximate location is about 0.45 mile southwest of the mouth of Alava Bay, adjacent to the northeast corner of an unnamed lake at 202 feet elevation. The site is in section 6, T. 77 S., R. 95 E., of the Copper River Meridian. It corresponds to loc. 99 in Elliott and others (1978). The location probably is accurate within 0.2 mile.

Comments on the geologic information

  • Geologic Description = This part of Revillagigedo Island is underlain by an assemblage of undivided Mesozoic or Paleozoic, metamorphosed sedimentary, volcanic, and intrusive rocks. This assemblage is intruded by a stock, dikes, and sills of Cretaceous granodiorite, and by a plug and associated dikes of ultramafic hornblendite and pyroxenite, also of Cretaceous age (Berg and others, 1988). The undivided assemblage and some of the Cretaceous granodiorite were regionally metamorphosed to greenschist grade in middle or Late Cretaceous time. These metamorphic rocks subsequently were remetamorphosed to hornblende hornfels grade near the contacts of intrusive rocks that were emplaced after the regional metamorphism. According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in granodiorite near the contacts both of the undivided metamorphic assemblage and of an ultramafic plug, apparently was staked for uranium or for other radioactive minerals. No other information about it has been made public.
