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 (Geology): THE DEPOSITS ARE CONFINED TO THE HIGHLY ALTERED DIORITE WHICH INTRUDES THE HAVALLAH FM.

Comment (Deposit): THE GROUP OF MINES WERE LOCATED IN 1873 & WORKED INTERMITTENTLY UNTIL 1945. THE JERSEY VALLEY MINE PRODUCED CONSIDERABLE SHIPPING ORE FROM 1880 TO 1910. SMALL SHIPMENTS FROM REX GROUP OF CLAIMS AND JERSEY VALLEY MINE MADE FROM 1921 TO 1929. MINES WERE DEVELOPED BY SHAFTS, ADITS, AND TUNNELS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Workings): SHAFTS, ADITS, TUNNELS. MODERATE-SIZED DUMPS

Comment (Commodity): OTHER ORE MINERALS NOT GIVEN IN THE LITERATURE

Comment (Location): W FLANK OF FISH CREEK MTNS.

Comment (Development): NO ACTIVITY IN 1984.

Comment (Deposit): THE MOST EXTENSIVE WORKINGS ARE ALONG A N10W, 60SW VEIN WHICH CUTS LIGHT GREY CHERT AND OLIVE SILTSTONE STRIKING N-20W, DIPPING ABOUT 90. THE MINERALIZED FAULT ZONE CONSISTS OF -PATCHY FINE-GRAINED QUARTZ AND OCHEROUS LIMONITE GOSSAN. MALAC-HITE AND OXIDE ARSENIC? MINERALS WERE NOTED. MINERALIZED ZONE -WAS STOPED OVER A WIDTH OF 50 CM OR MORE NEAR THE SURFACE.
