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 ASSOCIATED WITH FAULT AT WEST END OF AND ON NW SIDE OF SALT CREEK GRABEN, WHICH TRENDS NE AT RIGHT ANGLE TO SINBAD VALLEY GRABEN. PRINCIPAL FAULT TRENDS N 40 E, DIPS NEARLY VERTICAL. BEST ORE DEVELOPED IN LOWER WINGATE SANDSTONE JUST ABOVE CONTACT WITH UNDERLYING CHINLE FM. ORE CONSISTS PRIMARILY OF CHALCOPYRITE AND LUZONITE, LARGELY OXIDIZED. SMALL MASSES OF CHALCOCITE CARRY DISSEMINATED CHALCOPYRITE AND BORNITE. OCCURRENCE OF AG UNCERTAIN BUT LIKELY IS SIMILAR TO OTHER CU-AG DEPOSITS IN REGION, PROBABLY WITHIN CU SULFIDE.
Comment (Workings): MINE DEVELOPED BY THREE ADITS. LOWER ADIT DRIVEN GENERALLY N 35 W FOR 225 FT, THENCE GENERALLY N 20 E FOR 280 FT. UPPER ADIT LOCATED 275 FT NW OF LOWER, DRIVEN GENERALLY N 40 E FOR 425 FT; NEAR FACE IS 125-FT RAISE FROM LOWER LEVEL. EXTENT OF THIRD ADIT UNKNOWN.
Comment (Production): PARTIAL PRODUCTION RECORD. EXACT FIGURES UNKNOWN FOR EARLY YEARS, BUT PRODUCTION IS CONSIDERED TO BE SMALL.
Comment (Development): MINE PRODUCED SMALL AMOUNT OF HIGH-GRADE CU-AG ORE ABOUT TIME OF PYRAMID GROUP ACTIVITY (1909-1916). LAST REPORTED PRODUCTION WAS IN 1942.
Comment (Location): MINE SITUATED ON CLIFF NW OF SALT CREEK AT POINT WHERE CREEK LEAVES SINBAD VALLEY. ; INFO FROM LAND.ST :1975
