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 (Production): THREE CARLOADS OF ORE WERE SHIPPED PRIOR TO 1911. NINETEEN CARLOADS OF ORE WERE SHIPPED BETWEEN 1917 AND 1921; THIS ORE AVERAGED 7% CU, 6 OZ/TON AG, AND $2/TON AU. APPROXIMATELY 1000-2000 TONS OF 1-2% CU ORE REMAINS ON THE DUMP AND IN THE WORKINGS (PATTY, 1921, P. 244).

Comment (Geology): MINERALIZATION IS IN A SHEAR ZONE IN QUARTZ DIORITE OF JURASSIC-CRETACEOUS (?) SILVER NAIL LAKE PLUTON (FOX, 1970).
