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 = Gamble, 1986

Comment (Workings): Workings / Exploration = No workings or exploration activities are known at this locality.

Comment (Geology): Age = Unknown; not clear if this is a metamorphosed anomaly or if it is superimposed on the metamorphic rocks.

Comment (Geology): Geologic Description = Gamble (1988) reports that a quartz boudin in chlorite schist from this locality contained 0.1 ppm Au. Bedrock exposures are limited in this area; this occurrence may be close to a regional contact between lower Paleozoic mafic metavolcanic and metasedimentary assemblages (Till and others, 1986).

Comment (Deposit): Model Name = Quartz boudin in chloritic schist

Comment (Exploration): Status = Inactive
