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.

Comments
Comment (Deposit): DEPOSIT LIES IN NARROW GRABEN TRENDING N 10 TO 15 W BOUNDED BY NEARLY PARALLEL STEEPLY NE-DIPPING FAULTS AND CONTAINING SHEARED LEADVILLE LIMESTONE BRECCIA UP TO 60 FT WIDE, SOME IN FAULT CONTACT WITH BELDEN FM SHALES. SULFIDES OCCUR AS DISSEMINATED CRYSTALS AND COLLOFORM CRUSTS CEMENT, REPLACE, AND PARTLY FILL VUGGY LIMESTONE BRECCIA. SULFIDES FAIRLY COMPLETELY OXIDIZED. SMITHSONITE BOXWORKS REPLACE CRUSTS AND DISSEMINATED SPHALERITE CRYSTALS. MUCH OF SMITHSONITE THAT REPLACES ADJACENT CALCITE HAS FURTHER ALTERED TO HYDROZINCITE. CERUSSITE LOCALLY REPLACES GALENA; LIMONITE STAINS AND PSEUDOMORPHS AFTER MARCASITE CAVITIES FROM REPLACE SPHALERITE COATED WITH MN OXIDES, POSSIBLE RESIDUE OF MANGANOAN SPHALERITE. SELENITE CRYSTALS IN VUGS SUGGEST SUPERGENE DEPOSITION BY SULFATE-RICH SOLUTIONS FROM OXIDIZING ORES. ABUNDANCE OF HYDROZINCITE AND LATERAL EXTENT OF SULFIDE OXIDATION SUGGEST DEPOSIT IS NEAR LATE PROGRESSIVE STAGE OF OXIDATION. SIMPLE MINERALOGY, LEANNESS OF AG, COLLOFORM
Comment (Deposit): CRUSTS, OPEN VUGS, COARSE DISSEMINATED CRYSTALS, AND ABUNDANT CARBONATE GANGUE INDIGATE LOW-TEMPERATURE EPITHERMAL DEPOSITION SIMILAR TO MISSISSIPPI VALLEY-TYPE ZN DEPOSITS.
Comment (Workings): MINE DEVELOPED BY 3 TUNNELS ON FOUR LEVELS ALL BEARING GENERALLY N 10 TO 15 W. UPPER LEVEL PORTAL ELEV. 7525 FT WITH 50-FT DRIFT AND 25-FT WINZE AT END; MAIN LEVEL PORTAL ELEV. 7400 FT WITH 240-FT TUNNEL AND 90-FT WINZE TO LOWER LEVELS AT 25 FT FROM PORTAL; FIRST LEVEL PORTAL ELEV. 7379 FT WITH 110-FT DRIFT; SECOND LEVEL ELEV. 7331 FT WITH 75-FT DRIFT. MAJOR STOPES (SOUTH, FISHER, AND NORTH) DEVELOPED ON MAIN LEVEL.
Comment (Production): PRODUCTION REPORTED AS RECOVERABLE METALS. INTERVENING YEARS MAY HAVE BEEN LISTED IN USBM AS SHIPMENTS TO SMELTERS, BUT THIS IS UNCONFIRMED. AN NOT REPORTED IN 1927; CU NOT REPORTED IN 1927 AND 1947; TRACE CU REPORTED IN 1951.
Comment (Location): PROBABLY IN CANYON TRIBUTARY TO EAST RIFLE CREEK ABOVE RIFLE FALLS FISH HATCHERY. ; INFO FROM LAND.ST :(1975)
Comment (Development): FIRST OPENED AS GRANDVIEW MINE IN 1925 AND OPERATED UNTIL 1932. REOPENED IN 1940 BY LALE HARMON AND PRODUCED PERIODICALLY UNTIL 1951. ONLY BASE METAL MINE THAT OPERATED IN DISTRICT.
