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.

Land ownership: Private
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.

Comment (Workings): DEVELOPMENT CONSISTS OF A 250-FT ADIT INTERSECTING A 205-FT SHAFT, WITH SMALL STOPES AND CROSSCUTS. TWO CROSSCUTS, 560 FT AND 150 FT LONG, WERE DRIVEN NEARBY. A 15-TON MILL WAS OPERATED TO RECOVER GOLD-SILVER.
Comment (Geology): MINERALIZATION IS LOCALIZED IN THE FAULTED AND BRECCIATED ZONE ALONG OR NEAR THE KOIPATO RHYOLITE-SHALE CONTACT. OTHER COPPER MINERALIZATION CAN BE SEEN IN SHATTERED ZONES IN THE SHALES. FAULTING DIPS PARALLEL TO THE BEDDING OR ABOUT 65 DEGREES WEST. VEIN IS 3-10 FT WIDE WITH A ZONE OF ABOUT 10 FEET ON EITHER SIDE OF VEIN THAT IS FRACTURED AND FILLED WITH SECONDARY COPPER SULFATE. THE MINERALIZED ZONES OF FRACTURING ARE ASSOCIATED WITH AND TREND ROUGHLY PARALLEL TO FAULT ZONES.
