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 (Location): UNSURVEYED AREA ; INFO FROM LAND.ST :(1972)

Comment (Deposit): LENSES OF GARNET TACTITE ALONG LIMESTONE LENSES, NOT ON DEFINITE IGNEOUS CONTACTS. ONE AREA OF STOCKWORKS WITH SMALL PEBBLE DIKE WAS SAMPLED. THIS OUTCROP WAS FE-OXIDE-STAINED, LACED WITH QUARTZ VEINLETS, BLACK-APPEARING SILICA VEINING, AND MATRIX FOR PEBBLE DIKE. ROCK CONTAINS POINTS OF YELLOW AND BROWN FE OXIDE, ALSO SPECKS OF A BLACK METALLIC MINERAL. NEAR THE MAIN ROAD, A MAJOR FAULT ZONE SEPARATES SHALEY ROCKS TO THE WEST FROM TACTITES, LIME STONES, ETC. TO EAST. THIS COULD BE A MAJOR THRUST FAULT. IN THIS SAME AREA, IN AN OUTCROP OF LIMESTONE, A NARROW (20CM) LENS OF SILICEOUS GOSSAN OUTCROP HAS A STRIKE LENGTH OF ABOUT 2M, SHOWING GOOD BOXWORK STRUCTURE (SPHALERITE?).
