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.
Location: The Stone Lode prospect is located at an elevation of 1,250 feet (381 m) in Section 16, T. 27 S., R. 21 E., of the Kateel River Meridian. The reporter visited the site in 1989 and 1996.
Geology: 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.
Workings: Only surface workings have been completed at the Stone Lode prospect. No assay data are available.
Alteration: Tactite.
Production: 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).
Commodities (Major) - Ag, Au; (Minor) - Bi
Development Status: Undetermined.
Deposit Model: Copper-gold skarn (Cox and Singer, 1986; model no. 18b)
