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.

Comments

Comment (Workings): SHALLOW PITS

Comment (Geology): GEOL.COM: AT WEST END, MN-OXIDE VEINLETS OCCUR ALONG A LEDGE IN A 40-FT WIDE ZONE; ONE CLAIM HAS A 5-FT WIDE VEIN.

Comment (Deposit): DEVELOPED BY SHALLOW PITS. MANGANIFEROUS OUTCROPS ARE DISTRIBUTED ALONG AN AREA A MILE WIDE AND 2 MILES LONG FROM E. TO W.PROBABLY NOT THE SAME AS BLACK DIABLO MINE, AS SUGGESTED BY JOHNSON IN NBMG BULL 89. THESE CLAIMS ARE LOCATED ON T-HE WEST SLOPE OF BUFFALO MOUNTAIN WITH ELEVATIONS RISING FROM -WEST TO EAST, WHILE BLACK DIABLO MINE IS ON THE EAST SLOPE OF -THE SONOMA RANGE ACROSS THE PUMPERNICKEL VALLEY

Comment (Location): W. SLOPE OF BUFFALO RANGE. PROBABLY NOT FAR FROM BLACK TOP AND BLACK HAWK PROSPECTS, WHOSE DESCRIPTIONS ARE SIMILAR, AND BOTH ARE LOCATED O-N BUFFALO MOUNTAIN

Comment (Deposit): MN-RICH AREAS DISTRIBUTED IN A 2 MILE-BY-ONE MILE AREA.
