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 (Development): EARLY HISTORY OF DISTRICT LARGELY UNKNOWN. DISCOVERIES AND EARLY MINING IN GUNNISON GOLD BELT AREA LED TO ESTABLISHMENT OF SMALL MINING TOWNS OF DUBOIS, SPENCER, VULCAN, MIDWAY, AND CHANCE IN LATE 1880S. POST-1900 RECORDS INDICATE ONLY INTERMITTENT PRODUCTION FROM SEVERAL LARGER MINES, SUCH AS HEADLIGHT, OLD LOT, ANACONDA (GOOSE CREEK DISTRICT), CONTINENTAL (BEAVER CREEK DISTRICT, LUCKY STRIKE AND LULA. CLAIMS IN GREEN MOUNTAIN DISTRICT SURVEYED AND PATENTED BETWEEN 1894 AND 1905. PROBABLY MOST MINES WERE DEVELOPED BY ABOUT 1900. LATEST ACTIVITY REPORTED WAS ORE PRODUCTION FROM LULA MINE IN 1935 AND ORE PRODUCTION FROM LUCKY STRIKE MINE IN 1922 AND 1933-1934.
Comment (Location): DISTRICT LIES IN GREEN MOUNTAIN AREA AND INCLUDES UPPER PORTIONS OF GRAFLIN GULCH, DIRIGO GULCH, DUTCH GULCH, SAGE HEN GULCH, CHANCE GULCH, STUBBS GULCH, MERRY-GO-ROUND GULCH, LONG GULCH, AND COTTONWOOD GULCH. LANDMARKS INCLUDE GREEN MOUNTAIN (ELEV 9442) AND SCHISTO BASIN. DISTRICT ACCESSIBLE VIA ROAD AND TRAIL UP STUBBS GULCH (VIA GOLD BASIN CREEK) SOUTH FROM GUNNISON; VIA TRAILS UP LONG GULCH SOUTH FROM U.S. RTE 50; VIA TRAIL UP COTTONWOOD GULCH WEST FROM COCHETOPA CREEK AND COLORADO RTE 114. ELEV AND LAT-LONG GIVEN ARE FOR OLD TOWNSITE OF IRIS ON UNNAMED TRIBUTARY OF LONG GULCH IN S S2 S2 SEC. 14, T48N, R1E. ; INFO FROM LAND.ST :1976
Comment (Workings): PRINCIPAL MINES DEVELOPED BY VERTICAL AND INCLINED SHAFTS UP TO 200 FT DEEP AND ON AS MANY AS FOUR LEVELS, WITH DRIFTS AND STOPES. NUMEROUS SURFACE PROSPECTS. OLD 5-STAMP MILL AT LUCKY STRIKE MINE.
Comment (Deposit): BLM CLAIM RECORDS ASSIGN DISTRICT NAME OF "GREEN MOUNTAIN" BUT DISTRICT ALSO HAS BEEN KNOWN BY POPULAR NAME OF "IRIS." INDIVIDUAL RECORDS PREPARED FOR PRINCIPAL MINES AND TYPES OF MINERALIZATION: DENVER CITY, GRAFLIN, LUCKY STRIKE, LULA, MINERAL HILL, SHAUNEE NO. 33 PROSPECT.

Comment (Deposit): DISTRICT LIES NEAR NE END OF GUNNISON GOLD BELT. COUNTRY ROCK CONSISTS OF THICK SEQUENCE OF DUBOIS GREENSTONE FELSITE UNIT THAT AFIFI (1981) SUBDIVIDED INTO DACITIC, ANDESITIC LAPILLI TUFF, RHYOLITE, BASALTIC, AND ALKALI-FELDSPAR RHYOLITE MEMBERS. UNIT INTRUDED BY METAGABBRO (AMPHIBOLITE) DIKES AND SILLS AND FOLDED ALONG STEEPLY PLUNGING, TIGHT, DISHARMONIC IRIS SYNCLINE, ACTUALLY TWO SYNCLINAL SURFACE SEPARATED BY TIGHT ANTICLINAL FLEXURE. CUTTING SUCCESSIVELY UPSECTION THROUGH FELSITE UNIT IS SUBVERTICAL, GENERALLY N 45 W-TRENDING LULU FAULT, WHICH DISPLACES FELSITE ON NE AGAINST OLDER METASEDIMENTARY SEQUENCE ON SW. LATTER IS CUT BY GOLD BASIN QUARTZ DIORITE STOCK. QUARTZ VEINS AND METARHYOLITE DIKES CUT OLDER METASEDIMENTS, FELSITE, AND AMPHIBOLITE AND POSTDATE LULU FAULT. PRINCIPAL DEPOSITS ARE STRATABOUND MASSIVE SULFIDES CHARACTERIZED BY SPHALERITE-PYRITE-CHALCOPYRITE AND INTERPRETED TO BE SYNGENETIC, SUBMARINE, PREMETAMORPHIC. THIS TYPE IS REPRESENTED IN GRAFLIN AND DENVER
Comment (Deposit): CITY MINES AND SHAUNEE NO. 33 PROSPECT. SECOND MINERALIZATION TYPE IS POSTMETAMORPHIC, EPIGENETIC VEIN ON AND NEAR LULU FAULT AND CONSISTING OF QUARTZ-PYRITE+/-BIOTITE+/-SERICITE+/-TOURMALINE+/-CARBONATE+/-FLUORITE. DEPOSITS ARE SPATIALLY AND PROBABLY GENETICALLY RELATED TO GOLD BASIN STOCK TO SOUTH. THIS TYPE IS REPRESENTED IN LUCKY STRIKE, LULA, AND MINERAL HILL MINES.
