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 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): 75 NE TO 55 SW. APPARENTLY SOME CYMOID LOOP DEVELOPMENT WITH SPLITTING AND JOINING OF SUBSIDIARY VEINS. MAMMOTH-REVENUE VEIN AND VALLEY QUEEN VEIN (APPARENTLY) FOUND IN FOOTWALL; PAROLE VEIN FOUND IN HANGING WALL. VEIN ZONE COMPOSED OF THREE TYPES OF MATERIAL. FIRST TYPE IS QUARTZ AND SULFIDE ORE IN CENTER OF STRUCTURE. WIDE AREAS ARE HIGHLY BRECCIATED, OFTEN VUGGY WITH WATER-COURSE RESIDUES OF MO AND FE OXIDES. BRECCIATION DECREASED OR ABSENT IN NARROWER PARTS. ORE APPEARS AS RIBBONS OF FINE-GRAINED QUARTZ AND FINE-GRAINED PYRITE/MARCASITE INTERSPERSED WITH WHITE QUARTZ CONTAINING DISSEMINATED PYRITE/MARCASITE AND LATE GANGUE MINERALS. HIGHER GRADE ORE GENERALLY FOUND WHERE SULFIDES CONTAIN RELATIVELY LESS MARCASITE. LOW-MARCASTLE HIGH-GRADE ORE SHOWS AG/AU RATIOS OF 50:1 TO 100:1; HIGH-MARCASITE LOWER GRADE ORE SHOWS RATIO OF 10:1. HIGHER METAL VALUES USUALLY FOUND IN CENTER OF HANGING WALL PORTIONS. SECOND TYPE OF MATERIAL IS BROKEN, HIGHLY ALTERED WALLROCK IN SLABS AND BRECCIA
Comment (Location): MINE LOCATED SOUTH OF CONEJOS RIVER ON NW SIDE OF TOWN. ELEV AND LAT-LONG GIVEN ARE FOR SHAFT IN NE SE SW SEC. 15 (SECTIONS PROJECTED INTO UNSURVEYED AREA). ; INFO FROM LAND.ST :1975
Comment (Commodity): ORE MINERALS LISTED ABOVE ARE REPORTED FROM MAMMOTH-REVENUE MINE, AND ALTHOUGH NOT ALL ARE SPECIFICALLY NOTED AT OTHER MINES IN DISTRICT, THEY ARE GENERALLY APPLICABLE TO THEM (BIRD, 1973). ARSENOPYRITE REPORTED BY PATTON (1917) CITED FOR ENTIRE DISTRICT. PETZITE (TELLURIDE) REPORTED BY PATTON IN GILMORE AND PLATORO DISTRICTS WAS PROBABLY MISIDENTIFIED SULFIDE (BIRD, 1973). MINOR PRODUCTION OF CU AND PB UNCERTAIN DUE TO LACK OF OLDER PRODUCTION RECORDS.
Comment (Development): LAST REPORTED ACTIVITY WAS PUMPING, REHABILITATION, AND SAMPLING IN 1974
Comment (Deposit): VALLEY QUEEN IS NORTHERNMOST OF THREE MINES DEVELOPED ON SOUTH MOUNTAIN-PLATORO FAULT, LARGEST OF SEVERAL QUARTZ-PYRITE VEIN ZONES IN PLATORO FAULT ZONE. FAULT HAS BEEN INTERPRETED AS EXTENDING NW EITHER ON TREND WITH OR JOINING SOUTH MOUNTAIN FAULT OF SUMMIT AND DECATUR WEST DISTRICTS, AND SE INTO BIG LAKE RADIAL FRACTURE SYSTEM. FAULT TRENDS GENERALLY N 30 W WITH 80 TO 90 SW DIP. DUE TO MOVEMENT ON CORNWALL RESURGENT BLOCK IN FOOTWALL, STEEPER PORTIONS OF FAULT CONTAIN WIDER MINERALIZED ZONE THAN LESS STEEPLY DIPPING PORTIONS. DISPLACEMENT DECREASES SE FROM STUNNER PASS TO FOREST KING MTN-MAMMOTH MTN SADDLE. NORTH PART OF VEIN ZONE EXCEEDS 150 FT IN THICKNESS BUT DECREASES TO 50 FT SOUTH OF INTERSECTION WITH ENE-TRENDING EMMA CROSS-FAULT. IN MAMMOTH-REVENUE MINE, VEIN IS ACTUALLY VEIN ZONE CONSISTING OF NETWORK OF INTERWOVEN VEINS GENERALLY PARALLELING MAJOR FAULT BUT WITH CONSIDERABLE VARIATIONS, FROM N 0 TO 25 W IN STRIKE AND 85 NE TO 70 SW IN DIP. LESSER VEINS DIP VARIABLY FROM
Comment (Deposit): LENSES NEAR FOOTWALL. THIRD TYPE OF MATERIAL IS POST-MINERALIZATION, UNSILICIFIED, INCOMPETENT FAULT GOUGE TOWARD FOOTWALL.
Comment (Workings): 125-FT VERTICAL SHAFT WITH 50-FT CROSSCUT DRIVEN EASTWARD
