  • LITTLE HISTORICAL INFORMATION AVAILABLE FOR DISTRICT. CU NOTED IN SINBAD VALLEY BEFORE 1900, BUT FIRST CLAIMS (PYRAMID GROUP) APPARENTLY NOT SURVEYED UNTIL 1906. SMALL PRODUCTION FROM LEACH PLANT AT PYRAMID GROUP FROM 1908-1916. COPPER RIVET MINE WORKED ABOUT SAME TIME AND AGAIN IN 1940 AND 1942. COLORADO COPPER COMPANY ACQUIRED PROPERTIES IN 1942. PROSPECTS EXAMINED BY USBM IN 1942 AND 1945.

Deposit SINBAD VALLEY IS NW-SE-TRENDING SALT ANTICLINE ALONG NE MARGIN OF PARADOX BASIN AND NEXT TO UNCOMPAHGRE PLATEAU. PENNSYLVANIAN EVAPORITES OF PARADOX MEMBER OF HERMOSA FM ARE DEFORMED IN CENTER OF VALLEY AND IN PLACES ARE FAULTED AGAINST TRIASSIC-JURASSIC RED BEDS. GRABEN FAULTS, MORE COMPLEX ON SW MARGIN, DOWNDROP SEDIMENTS INTO VALLEY. SALT CREEK GRABEN TRENDS NE AT RIGHT ANGLE TO AND FROM NE MARGIN OF VALLEY. CU SULFIDES OCCUR AS VEINS IN FISSURES AND FRACTURES ASSOCIATED WITH GRABEN STRUCTURE WHERE THEY CUT FAVORABLE CLASTICS AND LIMESTONE. ORES ARE PRIMARILY CHALCOPYRITE, BORNITE, AND LUZONITE, OXIDIZED TO CARBONATES. HOST ROCKS INCLUDE LIMESTONE IN PARADOX MBR OF HERMOSA FM, CONGLOMERATE AND SHALE IN CUTLER FM (PERMIAN), CHINLE FM (TRIASSIC), AND TRIASSIC-JURASSIC? WINGATE SANDSTONE. DISSEMINATED CU SULFIDES OCCUR IN WINGATE SANDSTONE AND KAYENTA FM ALONG FAULTS AT SE END OF VALLEY. ORE CONSISTS OF CHALCOCITE, MALACHITE, AND AZURITE IMPREGNATING SANDSTONE IN LAYERS AND SMALL
Deposit IRREGULAR BODIES. OCCURRENCE OF AG UNCERTAIN BUT IF SIMILAR TO OTHER CU-AG DEPOSITS IN REGION, IS PROBABLY CONTAINED IN ONE OF IRREGULAR BODIES. OCCURRENCE OF AG UNCERTAIN BUT IF SIMILAR TO OTHER CU-AG DEPOSITS IN REGION, IS PROBABLY CONTAINED IN ONE OF CU SULFIDES.
