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 (Workings): SEVERAL SHAFTS, NUMEROUS DRILL ROADS AND ROTARY HOLES; ADITS, CUTS

Comment (Deposit): A NUMBER OF E-W-TRENDING HYDROFRACTED BRECCIA ZONES WITH ANASTOMOSING QUARTZ VEINLETS CUTTING INTERBEDDED PHYLLITE AND SANDSTONE, WITH IRON OXIDES AFTER PYRITE. THE QUARTZ IS WELL CRYSTALLIZED, COMMONLY VUGGY, WITH CRYSTALS FORMING ROSETTES AROUND BRECCIA FRAGMENTS. DENSITY OF DRILLING PATTERN IN AREA INDICATES THAT SOME GOLD MINERALIZATION IS PRESENT. QUARTZ VEIN WITH BRECCIA AND JASPEROID ALONG SHEAR ZONE.

Comment (Development): WORKED ABOUT 1915. FAIRLY RECENT DRILL ROADS AND ROTARY DRILL HOLES, ALTHOUGH NO ACTIVITY AT TIME OF EXAMINATION IN 1985. DRILLING PROBABLY IN MID-LATE 1970'S.
