The Sulphur Deposit is a aluminum, potassium, and sulfur mine located in Humboldt county, Nevada at an elevation of 4,600 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Location): 3 MI E OF SULPHUR RR STATION IN WESTERN FOOTHILLS OF THE KAMMA MTNS. TOWNSHIP, RANGE, AND SECTION INFERRED. SECTION LINES NOT YET SURVEYED
Comment (Reserve-Resource): ITEM 1: MEASURED RESERVE; ITEM 2: INDICATED PLUS INFERRED RESERVE IN VEINS EST BY GARDNER (UNPUB. REPT., 1944)
Comment (Commodity): PROJECT 9350 - 01393 ALUNITE RESOURCES
Comment (Reserve-Resource): TENTATIVE RESOURCE EST BY HALL CONSIDERS ALUNITIZED WALL ROCK LOW - GRADE ORE. POTENTIAL IS POOR.
Comment (Deposit): VEINS OF ALUNITE LOCATED NORTH OF THE MAIN SULFUR DEPOSITS. PRODUCTION WAS FROM 3 MAIN VEINS THAT ARE IN SHARPLY DEFINED FISSURES AND WERE PARALLEL. AVERAGE VEIN THICKNESS IS 4 FT. SEVERAL OTHER VEINS PRESENT WITH 2 ADDITIONAL FISSURE VEINS 1400 FT. WEST OF THOSE MENTIONED ABOVE, ONE 20 FT. WIDE BUT CONTAINING LOWER GRADE ALUNITE. STRIKE OF THE VEINS IS PARALLEL TO THE GENERAL TREND OF THE ALTERED AREA. VEINS OCCUR IN 2 PARALLEL SWARMS 1200 FT. APART. STRIKE RANGES FROM NORTH TO N 30 DEG. E. SIZE/DIRECTIONAL DATA GIVEN IS FOR ALUNITE DEPOSIT.
Comment (Production): MORE THAN 3000 ST OF VEIN ALUNITE PRODUCED, 500 TONS OF WHICH WERE SHIPPED TO CALIFORNIA AS DIRECT APPLICATION FERTILIZER. HOWEVER, THIS AREA IS BETTER KNOWN FOR SULFUR MINING AND A TOTAL OF SOME 40,000 ST. OF S SAID TO HAVE BEEN PRODUCED INTERMITTENTLY BY VARIOUS COMPANIES BETWEEN 1875 AND 1929 . SMALL PROD. OF AG AND OF HG ALSO REPORTED FROM SULFUR DEPOSITS AND NEIGHBORING TERRANE.
Comment (Geology): GARDNER (1944, UNPUB. REPT.) DESCRIBES TWO UNITS, ONE WHITE OVERLYING A BROWN UNIT, WHICH IS HOST FOR ALUNITE VEINS. HOST ROCKS ARE TUFF BRECCIAS, POSSIBLY WELDED, STRONGLY ALTERED.
Comment (Workings): SMALL OPEN PITS WORKED FOR SULFUR NOT ALUNITE . OLD ALUNITE WORKINGS VISIBLE AS ABANDONED OPEN STOPES IN 3 NEARLY VERTICAL VEINS. 2 OR MORE ADITS HAVE BEEN DRIVEN IN EACH IMPORTANT VEIN OR GROUP OF VEINS AND 2 SHAFTS WERE DRIVEN IN THE WESTERN VEIN GROUP. TOTAL LENGTH OF THE ADITS IS 400 - 500 FT.

Nevada Gold
Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
