Comments on the production information

  • PARTIAL PRODUCTION RECORD. ANNUAL TOTALS UNAVAILABLE FOR 1899-1918. CUMULATIVE TOTALS FOR 1899-1905 FROM EMMONS, 1906. NO PRODUCTION CITED IN CDM RECORDS FOR 1919-1921, 1923-1936, 1938, 1940-1971, AND AFTER 1972. ANNUAL FIGURES FOR 1938-1955 FROM USBM MINERAL YEARBOOKS. FIGURE FOR 1939 INCLUDES SMALL PRODUCTION FROM INDEPENDENCE NO. 7 CLAIM; FIGURE FOR 1940 INCLUDES SMALL PRODUCTION FROM TALBERT CLAIM. CU PRODUCTION IN 1955 WAS COVELLITE SPECIMENS FOR ROCK SHOP. PRODUCTION FIGURES RECORDED FOR DISTRICT ALSO IN 1957-1958, 1960, AND 1964, BUT MINERAL YEARBOOKS DID NOT STATE WHETHER OR NOT ALL OR BULK OF THIS PRODUCTION WAS CREDITED TO CASHIN MINE.

Comments on the reserve resource information

  • NEW STAR CORP. (IN MINING RECORD, 120281)

Comments on the workings information

  • MINE DEVELOPED BY MAIN TUNNEL 2900 FT LONG WITH 600-FT-LONG OVERHEAD STOPE AND TWO 300-FT RAISES. THREE LEVELS DEVELOPED OFF 260-FT INCLINED WINZE: 100 LEVEL WITH 300-FT NORTH AND 180-FT SOUTH DRIFTS, 160 LEVEL WITH 100-FT NORTH AND 100-FT SOUTH DRIFTS, 260 LEVEL WITH 30-FT NORTH AND 30-FT SOUTH DRIFTS. MAUD TUNNEL IS 380 FT LONG WITH 80-FT SHAFT AT PORTAL. TWO LEACH PONDS CONSTRUCTED NEAR MAIN TUNNEL TO TREAT DUMP MATERIAL.

Comments on development

  • DEPOSIT DISCOVERED IN 1896 BUT NO ACTIVE DEVELOPMENT TOOK PLACE UNTIL 1898. FIRST OPERATOR APPARENTLY WAS LA SAL COPPER MINING COMPANY WHO SOLD PROPERTY IN 1918-1919 TO MICHIGAN-COLORADO COPPER COMPANY. DUE TO HIGH TRANSPORTATION COSTS IN EARLY YEARS, ONLY HIGH-GRADE SULFIDE AND NATIVE CU ORE COULD BE MINED. SMALL LEACH PLANT AND SMELTER PRODUCED MATTE IN EARLY 1900S, USING PYRITE FROM OPHIR AND COAL FROM OVENS WEST OF NATURITA. INTERMITTENT PRODUCTION TOOK PLACE BY VARIOUS OPERATORS FROM 1922-1946. FURTHER EXPLORATION/DEVELOPMENT AND REHABILITATION CONDUCTED BY CASHIN COPPER CORP IN 1955, INTERSTATE OIL AND GAS IN 1962, GOLD BAR RESOURCES IN 1963-1965, AND AUSTIN SMITH IN 1972 WHO SHIPPED 50 TONS OF DUMP ORE TO LEACH PLANT IN LISBON VALLEY, UTAH, BUT NO VALUES WERE RECOVERED. IN 1981, NEW STAR CORP ACQUIRED PROPERTY (MINING RECORD, 12/2/81), DID EXPLORATION AND DEVELOPMENT, AND SHIPPED TRIAL LOT OF 500 TONS OF ORE THAT WERE SUCCESSFULLY MILLED.

General Incorporate info from 10231935 (MRDS D010953, MAS 0080850671) with this record. The only additional info was Sumito Minerals as the owner, IFOC as reporter, Austin Smith as Operator in 1972, and several vague references.
Deposit DEPOSIT OCCURS IN WINGATE SANDSTONE ON SW LIMB PARADOX VALLEY ANTICLINE. ALTHOUGH FLANK OF FOLD IS CHARACTERIZED BY NUMEROUS GRABEN-TYPE NORMAL FAULTS TRENDING NW-SE AND DOWNTHROWN ON NE, CASHIN-CLIFFDWELLER DEPOSITS LOCALIZED IN VEINS ALONG TWO FAULTS TRENDING GENERALLY N 20 E (CLIFFDWELLER) AND N 45 E (CASHIN), POSSIBLY REPRESENTING EXTENSIONS OF SALT INTRUSIVE BULGES FROM INTERIOR OF PARADOX VALLEY (SIMILAR TO FAULT AT SUNRISE MINE ON NORTH SIDE OF VALLEY). ORES CHARACTERIZED BY ARGENTIFEROUS CU SULFIDES, CU ARSENIDES, NATIVE CU AND NATIVE AG. REPLACEMENT ORE CONSISTS OF SHORT BLADED AGGREGATES OF CHALCOPYRITE REPLACING SAND GRAINS, IN TURN REPLACED BY COVELLITE; MINOR ASSOCIATED SPHALERITE. VEIN ORE CONSISTS OF DOLOMITE FILLING VEIN AND CEMENTING BRECCIA OF SPHALERITE, GALENA, CHALCOPYRITE, AND FINE-GRAINED INTERGROWTH OF CHALCOPYRITE AND UNKNOWN SULFIDE; SOME ORE CARRIES BORNITE AND CHALCOCITE. LATER LUZONITE AND COVELLITE CUT AND REPLACE GANGUE AND EARLY SULFIDES. ARBOREAL
Deposit MASSES OF ARGENTIFEROUS NATIVE CU WEIGHED 400 TO 500 LB AND REPORTEDLY OCCURED IN RED BEDS (CHINLE FM) UNDERLYING WINGATE. ALTHOUGH SOME AGE RELATIONS WERE INCONCLUSIVE, FISCHER (1936) PROPOSED GENERAL PARAGENESIS: EARLY BARITE(?); PYRITE, EARLY CHALCOPYRITE, SPHALERITE, GALENA , CHALCOPYRITE INTERGROWTH; BORNITE, CHALCOCITE, TENNANTITE(?), UNKNOWN SILVERY WHITE MINERAL; (BRECCIATION OF ORE BY POSSIBLE FAULT MOVEMENT); DOLOMITE (CEMENTING); LUZONITE, COVELLITE. FISCHER (1936) BELIEVED NATIVE CU AND CU ARSENIDES TO BE OF HYPOGENE ORIGIN. LINES OF EVIDENCE FOR HYPOGENE ORIGIN FOR FINE-GRAINED CHALCOCITE: (1) REPLACEMENT OF SPHALERITE SIMULTANEOUSLY BY GALENA, BORNITE, CHALCOCITE, AND OTHER MINERALS; (2) REPLACEMENT INDEPENDENT OF FRACTURING; (3) GRANULAR TEXTURE AND INTERLOCKING GRAINS; (4) UNIFORM DISTRIBUTION OF SCATTERED MINERALS IN HOST SULFIDES; (5) ABSENCE OF EVIDENCE OF SUPERGENE ENRICHMENT.
