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 (Development): WORK PLANNED IN 1953 TO EXTEND LOWER ADIT TO INTERSECT MINERALIZATION AT DEPTH.

Comment (Location): INFO FROM LAND.ST :1983

Comment (Production): IN 1953 PROPERTY WAS PRODUCING SMALL, INTERMITTENT SHIPMENTS.

Comment (Deposit): PRINCIPAL MINERALIZATION OCURS ALONG A NORTHEAST: STRIKING DIKE WHICH IS DIFFICULT TO TRACE AT THE SURFACE

Comment (Workings): LOWER CROSSCUT, WEST PARK NO. 3 TUNNEL, 415 FT LONG AND PLANNED TO CUT GREEN MONSTER ORE AT 500 FT DEPTH. APPROXIMATELY 200 FT OF LATERAL WORKINGS IN TWO ADITS NEAR OUTCROP. ALL OPENINGS ACCESSABLE IN 1953

Comment (Geology): THE DEPOSIT FORMED NEAR CONTACT BETWEEN THE CLAYTON PEAK STOCK AND MISSISSIPPIAN LIMESTONES. A NORTHEAST STRIKING DIKE LOCALIZES MINERALIZATION.
