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 (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c)

Comment (Deposit): Other Comments = Also see Lookout Mountain (HE032).

Comment (Reference): Primary Reference = Unpublished report, Addwest Minerals International, Ltd, 1997

Comment (Geology): Age = Late Cretaceous or younger.

Comment (Exploration): Status = Active

Comment (Geology): Geologic Description = The Silverdikes prospect is on the Chulitna fault. The country rocks are Upper Jurassic to Upper Triassic crystal tuff, argillite, graywacke, and chert, cut by Upper Cretaceous or Lower Tertiary, fine-grained quartz porphyry dikes. The deposit apparently consists of galena- and sphalerite-bearing quartz veins, but their hostrock is not specified. The dikes contain disseminated pyrite. Geochemically anomalous silver, lead and zinc values are reported (unpublished report, Addwest Minerals International, Ltd, 1997). The Silverdikes prospect closely resembles the deposit at Lookout Mountain (HE032).

Comment (Workings): Workings / Exploration = Surface sampling only.
