The Frank Long is a silver and 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 (Reference): Primary Reference = Richter, 1970; Pilgrim,1933
Comment (Workings): Workings / Exploration = The vein was drifted along strike for 88 feet. A sample of quartz and arsenopyrite taken from the ore stockpile assayed 0.38 ounces of gold and 0.30 ounces of silver per ton (Pilgrim, 1933).
Comment (Geology): Geologic Description = The quartz vein at this prospect is hosted in Cretaceous Valdez Group graywacke (Richter, 1970). The vein varies from six to 24 inches in width; it strikes S45E and dips nearly vertical. The vein consists of white quartz and arsenopyrite with considerable graywacke fragments. The vein was drifted along strike for 88 feet. A sample of quartz and arsenopyrite taken from the ore stockpile assayed 0.38 ounces of gold and 0.30 ounces of silver per ton (Pilgrim, 1933).
Comment (Production): Production Notes = None reported.
Comment (Deposit): Model Name = Low-sulfide, Au-quartz vein (Cox and Singer, 1986; model 36a)
Comment (Deposit): Other Comments = This property is often combined with the Skinner property. The site is difficult to locate.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary; Boden and others (1991) report other veins in the district are about 55 m.y. old.
