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 (Development): ORIGINAL CLAIMS STAKED IN 1896 BY HEBER HOLT OF ENTERPRISE UTAH. CLAIMS WERE PATENTED IN 1910. LIMITED EXPLORATION AND MINING WAS CONDUCTED ON THE PROPERTY UNTIL 1957. SYSTEMATIC EXPLORATION BEGUN IN 1958 BY SAMUEL S. ARENTZ, BUT PROPERTY STILL UNECONOMIC. RANCHERS EXPLORATION TOOK CONTROL OF THE PROPERTY IN 1975. DRILLING AND TEST MINING BEGAN IN 1979. FULL MINE DEVELOPMENT BEGAN IN 1980. ORE FIRST FED TO THE MILL ON AUGUST 29, 1981. MINING ACTIVE TO PRESENT - MAY 1985 - AND IS EXPECTED TO CONTINUE FOR THE NEXT 10 YEARS. HECLA MINING COMPANY BOUGHT RANCHERS EXPLORATION IN LATE 1984 AND NOW OWN AND OPERATE MINE
Comment (Location): AREA OF MINING AND MINING CLAIMS COVERS MUCH OF THE SOUTHEAST QUARTER OF SECTION 2 ; INFO FROM LAND.ST :(1975)
Comment (Production): ESTIMATES BASED ON PROJECTED FIGURES IN 1982. MINING AND PRODUCTION IS CURRENTLY IN PROGRESS
Comment (Deposit): THE DEPOSIT OCCUPIES A CONTINOUS ZONE WITHIN THE ESCALANTE VEIN. THE VEIN AVERAGES 19 FEET WIDE AND MINERALIZATION OCCURS OVER THE ENTIRE WIDTH. VEIN IS MARKED BY CRUSTIFORM BANDING WITH BANDS OF FINE-GRAINED CRYSTALLINE QUARTZ AND QUARTZ WITH HEMATITE, CALCITE, OR FLUORITE, INCLUSIONS. SILVER IS ASSOCIATED WITH QUARTZ - HEMATITE BANDS. BRECCIATION AND REPEATED VEINING IS COMMON - TENTATIVE PARAGENESIS IS (1) EARLY BARREN-CALCITE PHASE, (2) LATER QUARTZ-FLUORITE PHASE, (3) EPISODIC DEPOSITION OF QUARTZ-SULFIDE, SILVER AND HEMATITE MINERALS, AND (4) A LATE QUARTZ-CALCITE PERIOD.
Comment (Workings): MAIN ACCESS IS VIA A FIGURE-EIGHT SPIRAL DECLINE WITH CROSSCUTS AT PERIODIC INTERVALS DRIVEN TO THE VEIN. DECLINE IS USED FOR REMOVAL OF ORE VIA DUMP TRUCKS. DECLINE WILL ULTIMATELY BE AT LEAST 5100 FOOT LONG. MINING METHOD IS END-SLICING, A VARIATION OF VERTICAL CRATER RETREAT MINING.
Comment (Geology): VOLCANICLASTIC HOST ROCK IS POST-MIDDLE MIOCENE IN AGE AND FILLS EAST-NORTH EAST TRENDING GRABEN STRUCTURE
Comment (Deposit): MINING CURRENTLY IN PROGRESS ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
