The Stone is a gold and silver 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 (Exploration): Status = Active
Comment (Reference): Primary Reference = Berg and Cobb, 1967
Comment (Workings): Workings / Exploration = Only surface workings have been completed at the Stone Lode prospect. No assay data are available.
Comment (Production): Production Notes = Some modest production activities in the form of test shipments of high grade ore by the owner may have taken place (Ted Almasy, personal communication, 1998).
Comment (Geology): Geologic Description = The Stone Lode prospect is a poorly known, but promising gold prospect in skarn near a limestone/monzonite contact; it is geologically very similar to Nixon Fork Mine (MD062). Mineralization consists of garnet-rich and wallastonite-idocrase-epidote skarn that replaces an Ordovician limestone near the margin of a small monzonite body that is currently undated.
Comment (Deposit): Other Comments = See Nixon Fork Mine (MD062). The Stone prospect is on in part on land selected or conveyed to Doyon Ltd. For further information, contact Doyon Ltd. at 210 1st Ave., Fairbanks, Alaska, 99701.
Comment (Deposit): Model Name = Copper-gold skarn (Cox and Singer, 1986; model no. 18b)
