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 (Workings): Workings / Exploration = No workings are known at his locality.

Comment (Reference): Primary Reference = Mulligan, 1962

Comment (Geology): Geologic Description = Cerussite has been identified in a limonitic float sample at this locality (Mulligan, 1962). No assay data are available. This is in high grade carbonate metamorphic rocks of probable Lower Paleozoic age (Till and others, 1986).

Comment (Deposit): Model Number = 19a ?; 22c ?

Comment (Deposit): Model Name = Polymetallic vein or replacement in marble (Cox and Singer, 1986; model 19a or 22c ?). May be similar to Foster propect (BN098).

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Cretaceous ; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age.
