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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Location): INFO FROM LAND.ST :(1972)
Comment (Deposit): OXIDE CU MINERALS AND LIMONITE OCCUR ALONG A BULLDOZER CUT FOR 30-40 M. AT ONE LOCALITY, THE MINERALIZATION APPEARS TO BE IN THE FOOTWALL OF A POSSIBLE N 20 E, 60 SE FAULT. THE CHRYSOCOLLA, MALACHITE AND LIMONITE OCCUR AS FRACTURE COATINGS. CALCITE COATS THE OXIDE CU MINERALS
Comment (Workings): BULLDOZER CUTS, PROBABLY 2 SHORT ADITS, AT LEAST 2 DRILL HOLES. ADIT ACROSS CANYON TO NORTH TRENDS APPROXIMATELY N 20 W AND MAY FOLLOW A FAULT.
