The Charles Frank is a gold 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 (Workings): Workings / Exploration = A 60 foot adit was driven N50W where it intersected the vein. A total of 51 feet of drift was driven along the vein eight feet to the southwest and 43 feet to the northeast (Pilgrim, 1933). Grab samples from the dump contained 0.04 ppm gold (Richter, 1970).
Comment (Geology): Age = Tertiary; Boden and others (1991) report other veins in the district are about 55 m.y. old.
Comment (Exploration): Status = Inactive
Comment (Production): Production Notes = An unknown amount of gold was produced between 1931 and 1933 (Pilgrim, 1933).
Comment (Deposit): Model Name = Low-sulfide, Au-quartz vein (Cox and Singer, 1986; model 36a)
Comment (Deposit): Other Comments = These prospects are within the Kenai Fjords National Park which is closed to mineral entry.
Comment (Reference): Primary Reference = Richter, 1970; Pilgrim, 1931
Comment (Geology): Geologic Description = The prospect consists of two quartz-arsenopyrite veins that cut Cretaceous Valdez Group black slate (Richter, 1970). Pilgrim (1933), describes the vein as being 8 to 14 inches wide, it trends N53E and dips 79N. Near the caved portal the black slate strikes N25E and dips 35W. A 60 foot adit was driven N50W where it intersected the vein. A total of 51 feet of drift was driven along the vein eight feet to the southwest and 43 feet to the northeast (Pilgrim, 1933). Grab samples from the dump contained 0.04 ppm gold (Richter, 1970).
