About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Land Status

Land ownership: BLM Administrative Area
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 (Development): NO ACTIVITY IN 1984. PROBABLY VERY MINOR PRODUCTION?

Comment (Deposit): DRUSY AND MASSIVE QUARTZ VEIN MATTER OCCURS ALONG A PROBABLE THRUST FAULT WHICH SEPARATES (IN GENERAL) HANGING WALL BLACK CHERT FROM FOOTWALL GREENSTONE. FAULT APPEAR TO ENCIRCLE ALMOST COMPLETELY AN INLIER OF LOWER PLATE. DIP OF THE FAULT VARIES FROM 25 TO 50 DEGREES. AT A WESTERN PIT, A HIGH-ANGLE (LATER?) CROSS-CUTTING FAULT (N 40 W, 80 SW) ALSO IS MINERALIZED. VEIN MATERIAL IS ENTIRELY OXIDIZED, AS ELSEWHERE IN THE DISTRICT. MALACHITE, COPPER PITCH, AND LIMONITE GOSSAN ARE COMMON. THE FOOTWALL TO THE VEIN IS A LIGHT GRAY GOUGE.

Comment (Workings): SEVERAL OPEN CUTS UP TO 10 X 10 M; SEVERAL SHORT ADITS, BULLDOZER CUTS.

Comment (Location): INFO FROM LAND.ST :(1972)
