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 (Geology): SULFUR IS IN VEINS IN PEBBLE CONGLOMERATE, PEBBLY, SANDSTONE, AND TUFFACEOUS SANDSTONE, AND DISSEMINATED IN CONGLOMERATE, AND AT ONE LOCALITY (PETERSON MINE) OCCURS ALONG A FAULT ZONE. LARGE MASSES OF SULFUR ARE QUITE PURE, BUT ORE MINED RUNS FROM 15 TO 38% S. CONCENTRATE IS BAGGED AND SHIPPED FOR USE AS A SOIL CONDITIONER. SILVER OCCURS AS CERARGYRITE (HORN SILVER) IN NARROW SEAMS NEAR THE SURFACE AT THE SOUTH END OF THE SULFUR DEPOSITS. ALUNITE OCCURS IN VEINS JUST EAST OF MOST OF THE SULFUR PITS. CINNABAR IS ASSOCIATED WITH SULFUR IN SMALL AMOUNTS. FINELY CRYSTALLINE CINNABAR OCCURS AS SUGARY COATINGS AROUND FRAGMENTS OF BOTH SILICIFIED AND UNSILICIFIED TUFF AND AGGLOMERATE. SOME CINNABAR IS DISSEMINATED THRU' TUFFS FORMING TYPICAL OPALITE ORE. ALUNITE OCCURS IN 3 PARALLEL VEINS RANGING FROM 2-15 FT. WIDE, DIPPING STEEPLY, CUTTING RHYOLITE BRECCIA. SILVER OCCURS IN THE SOUTH PART OF THE DEPOSITS NEAR DEVIL'S CORRAL. ALUNITE DEPOSIT MEASURES 100 FT X 250 FT BY AT LEAST 50 FEET THICK
Comment (Geology): ; GEOL.DESC: ROCKS ARE FLAT TO GENTLY DIPPING
Comment (Deposit): THE FIRST LOCATIONS WERE MADE IN 1875 BY MCWORTHY AND ROVER, AND SOON AFTER, BY HALE AND WRIGHT, WHO SOLD OUT TO PACIFIC SULPHUR CO., WHO ERECTED A REFINERY WHICH THEY RAN FOR ABOUT 8 YEARS, PRODUCING 6-7 TONS SULPHUR PER DAY. NEVADA SULPHUR CO. ACQUIRED THE DEPOSITS IN 1900, AND OPERATED THEM UNTIL 1917 WHEN THEY WERE SOLD TO THE CALIFORNIA REX SPRAY CO. WHICH WITH OTHERS, WAS ACTIVE UP UNTIL 1929. HANSEN, REED AND MILLER BUILT A 2-PI RETORT IN 1941, BUT PRODUCED NO HG. LESSEES INSTALLED A 15-TON FURNACE IN 1943. UNDER LEASE TO WESTERN SULFUR CORP. IN APRIL 1957. A MR. MOONSEY DISCOVERED AG AT THE S. END OF THE DEPOSITS IN 1908. 1000 ACRES OF PATENTED GROUND. S END WAS MINED BY QUARRYING OR ROOM-AND-PILLAR SYSTEM. THE PRESENCE OF ALUNITE WAS KNOWN AT LEAST AS FAR BACK AS 1900, BUT IT WAS NOT PAID MUCH NOTICE UNTIL 1917 WHEN SEVERAL CLAIMS WERE LOCATED. ; INFO.SRC : 1 PUB LIT
Comment (Production): 25 FLASKS TO END OF 1943, OF HG $381,723. WORTH OF SAND AG TO END OF 1943; AND VANDERBURG (1938) REPORTED AG PRODUCTION OF OVER $100,000. AT LEAST 40,000 TONS S. HAD BEEN PRODUCED TO 1938. ABOUT 500 TONS ALUNITE HAD BEEN SHIPPED BY 1938, FOR USE AS FERTIUZER. A 1968 REPORT ESTIMATES 327,000 LONG TONS 17.7% S. ORE OR 1,000,000 LONG TONS OF 13.2% S ORE AS RESERVES.
Comment (Deposit): 1000 ACRES OF PATENTED GROUND
Comment (Location): LOCATION TO CENTER OF SECTION 36
Comment (Reserve-Resource): RESERVES VERY SMALL
