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.
Mine Description
The Big Pine mine is about a mile west of the Senator, on the south side of Hassayampa Creek. Lindgren states that it “has four tunnels between altitudes of 7,000 and 7,400 feet and a 200 foot shaft with drifts 200 and 350 feet long. There is a cyanide plant on the property, which apparently has had little production. C. H. Dunning states that the vein occupies a fracture in quartz diorite and contains quartz and pyrite. The oxidation is said to be deep, and the ore shoots long and irregular. The vein strikes N. 35° W. and dips 70° NW. The ore is reported to contain $9 to the ton in gold and silver, about half of each by value.”

Comments
Comment (Geology): DEPOSIT IS QUARTZ VEIN WHICH CUTS PROTEROZOIC GRANODIORITE
Comment (Development): PATENTED CLAIMS - MAMMOTH, QUEEN, GRIZZLY, GOPHER, RUBY; UNPATENTED CLAIMS - GOLD STANDARD, GOLD EAGLE, PLURIBUS; OTHER CLAIMS AS WELL; MINE KNOWN AS THE ST. THERESA IS LOCATED ON CLAIMS OWNED BY LAWE WHICH MAY HAVE BEEN PART OF THE ORIGINAL BIG PINE GROUP BUT WHICH DID NOT APPARENTLY INCLUDE THE MAJOR BIG PINE WORKINGS
Comment (Workings): WORKINGS INCLUDE 7 TUNNELS (TUNNEL NO. 5 IS 1400 FT) AND TWO SHAFTS (ONE SHAFT IS 200 FT DEEP)
Comment (Location): LOCATED ON THE NORTH SLOPE OF MT. TRITLE
