Ace

The Ace is a uranium mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Reference): Primary Reference = Berg and others, 1988

Comment (Deposit): Other Comments = the site is in Misty Fiords National Monument Wilderness.

Comment (Geology): 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.
