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: 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.

Comments

Comment (Deposit): THE WILLARD GROUP INCLUDES THE SHEEPHERDER (LARGEST PRODUCER), TREASURE HILL, AND NEVADA HONEY BEE MINES. GOLD WAS FIRST DISCOVERED AT THE SHEEPHERDER CLAIMS IN 1915, SOME SILVER & COPPER WERE PRODUCED FROM THE SAME AREA BETWEEN 1905 AND 1912. UNTIL 1951, GOLD AND SILVER WERE MINED IN SMALL QUANTITIES FROM CLAIMS IN THE WILLARD GROUP OF MINES. THE NETWORK OF QUARTZ VEINLETS WAS DEVELOPED BY NUMEROUS TUNNELS, SHAFTS, ADITS, AND SCATTERED WORKINGS TOTALING ABOUT 1300 FEET. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Workings): NUMEROUS TUNNELS, SHAFTS, ADITS AND SCATTERED WORKINGS. OPEN STOPES. DRILL ROADS AND DRILL SITES APPROX. 3-5 YEARS OLD (1985).

Comment (Geology): ORE CONSISTED OF FREE-MILLING GOLD & SILVER IN COPPER-STAINED QUARTZ VEINS. ORE OCCURS IN CREVICES IN LIMESTONES AT AND NEAR THE CONTACT WITH THE UNDERLYING RHYOLITE. MINERALIZATION IS ALSO PRESENT IN BRECCIATED RHYOLITE CLOSE TO BASALT DIKES.

Comment (Production): LINE 8: INTERMITTENT PRODUCTION.

Comment (Development): GOLD WAS FIRST DISCOVERED IN 1915; SOME SILVER & COPPER WERE PRODUCED BETWEEN 1905 AND 1912. UNTIL 1951, GOLD AND SILVER WERE MINED IN SMALL QUANTITIES.
