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 (Exploration): Status = Inactive
Comment (Deposit): Other Comments = Chugach Alaska Corporation, Anchorage, Alaska has control of these lands.
Comment (Geology): Geologic Description = The prospect is in volcanic rock of the Tertiary Orca Group (Nelson and other, 1985). Capps and Johnson (1913) describe an auriferous quartz vein in greenstone. In 1915 they reported values of 121 oz Au/ton, but that the prospect was mined out (Capps and Johnson, 1915) and the shaft caved. Recent sampling of the prospect area yielded values of gold ranging from <0.03 ppm to 0.03 ppm (Jansons and others, 1984).
Comment (Geology): Age = Probably Tertiary based on the age of the host rock.
Comment (Reference): Primary Reference = Cobb, 1972 (MF-392)
Comment (Workings): Workings / Exploration = Recent sampling of the prospect area yielded values of gold ranging from <0.03 ppm to 0.03 ppm (Jansons and others, 1984).
