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 (Geology): Geologic Description = Massive gold-bearing pyrrhotite and pyrite in recrystallized Triassic limestone near contact with small granodiorite stock of Cretaceous age. Sulfide body is 52 ft by 19 ft by 34 ft and consists of about 75% pyrrhotite in coarse crystals up to 2 in in diameter.

Comment (Deposit): Model Name = Lode: massive sulfide, contact metasomatic

Comment (Deposit): Other Comments = See Nabesna mine, NB022

Comment (Production): Production Notes = Possibly some minor production

Comment (Reference): Primary Reference = Wayland, 1943, USGS B 933B, p. 184-185

Comment (Workings): Workings / Exploration = Average Au value of 14 samples was about 0.91 oz./t (reported as 32.00 dollars in Au); high value was 2.42 oz./t (reported as 85.00 dollars in Au, Au at 35.00/fine oz.) in USGS Bull. 933, p. 185. Surface and underground workings.

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Cretaceous

Comment (Commodity): Ore Material = marcasite in thin section
