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.

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): DISCOVERED IN 1936 BY D.J. WOOTAN, ALTHOUGH ORE WAS NOT LOCATED UNTIL 1938. A 2-TUBE RETORT WAS BUILT IN 1938, TO WHICH 2 MORE TUBES WERE ADDED IN 1939. THE CLAIM WAS ABANDONED SHORTLY THEREAFTER. DIABASE IS SO THOROUGLY ALTERED, IT CAN BE CUT WITH A PICK. THE MINERALIZED DIKE IS LESS THAN 10 FEET WIDE AND IS OFFSET BY NUMEROUS FAULTS, WITH SMALL DISPLACEMENT. SEVERAL LESSEES WORKED THE PROPERTY FROM 1939 TO 1943 AND THE PROPERTY WAS IDLE FROM 1943 TO AT LEAST 1956. DEVELOPMENT CONSISTS OF 3 INCLINED SHAFTS, 50 FT, 50 FT AND 100 FT. DEEP, PLUS ABOUT 400 FT OF UNDERGROUND WORKINGS. ; INFO.SRC : 1 PUB LIT
Comment (Geology): ORE BODIES MOST ABUNDANT WHERE DIKE WAS MOST-FAULTED. THE LARGEST ORE SHOOT WAS STOPED FOR 32 FT. ALONG THE DRIFT FROM A BLOCK 3-4 FT BY 6-12 FT IN CROSS-SECTION. THE ORE MINED WAS HIGH-GRADE; UP TO 60 POUNDS HG/TON. THE ORE MINERALS FILL VESICLES AND FRACTURES IN THE DIABASE, AND LOCALLY IMPREGNATE THE DIABASE AND ADJACENT TUFFS ; GEOL.DESC: FAULTED DIABASE DIKE CUTS BASALT AND TUFF
Comment (Location): S. OF RED ORE MINES; PREVIOUS QUAD DESIGNATION = BOTTLE CREEK (1961) 1:625000
Comment (Production): ORE GRADE AS HIGH AS 60 LB. HG PER TON
Comment (Development): 2 RETORTS
Comment (Deposit): ORE EMPLACEMENT OCCURS ALONG FAULTS IN A DIABASE DIKE; SCOSSA MINE (RED ORE NO 1) LOCATED ON NORTH END OF THIS DIKE
Comment (Workings): 3 INCLINED SHAFTS, DRIFTS

Nevada Gold
Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
