Kaiser Mine

The Kaiser Mine is a fluorine-fluorite mine located in Mineral county, Nevada.

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.

Mine Info

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.

Land Status

Land ownership: BLM Administrative Area
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 (Deposit): ALMOST ALL OF THE FLUORSPAR IS IN A FAULT ZONE FROM 2 TO 18 FEET IN WIDTH AND OVER 1800 FEET IN STRIKE LENGTH. FLUORSPAR GENERALL OCCURS IN A WELL-DEFINED VEIN WITH A DEFINITE FOOTWALL AND A LESS DEFINITE HANGING WALL IN WHICH IRREGULAR, RANDOM OR BRANCHING, THINNER VEINS AND VEINLETS ARE FOUND. ONLY RARELY DOES FLUORSPAR OCCUR BENEATH THE FOOTWALL CONTACT. THE MINERALIZED ZONE RANGES FROM A FEW INCHES TO 9 FEET OR MORE IN THICKNESS, AND THE MAIN VEIN WITHIN THIS ZONE COMMONLY IS A FEW INCHES TO SEVERAL FEET THICK WITH ABRUPT PINCHING AND SWELLING. IN PLACES, ESPECIALLY IN HANGING WALL, THE VEINS AND THE ADJACENT ALTERED ROCK ARE BRECCIATED. LOCALLY THE FLUORSPAR IS GRANULATED TO A LOOSE SANDY MATERIAL. SOME OF THE ORE IS STAINED BY IRON OXIDES OR, LESS COMMONLY, BY MANGANESE OXIDES. THE FLUORITE IS WHITE TO VERY LIGHT GRAY TO VERY PALE GREEN, AND CONSISTS MOSTLY OF MEDIUM-GRAINED CRYSTALS.

Comment (Geology): THE COUNTRY ROCK IS AN OLIVE-GRAY TO MEDIUM-GRAY ANDESITIC VOLCANIC ROCK WHICH IS SLIGHTLY ALTERED TO CALCITE, SERICITE, AND CHLORITE. IN THE FAULT ZONE THE COUNTRY ROCK IS ARGILLIZED, SILICIFIED, AND SOMEWHAT IRON STAINED; IT NOW CONSISTS OF QUARTZ, MONTMORILLONITE, AND A MINOR AMOUNT OF SERICITE.

Comment (Workings): 6 INCLINED SHAFTS WITH 6 PRINCIPAL LEVELS. ALL MINE DEVELOPMENT BELOW THE 400 LEVEL DONE BY KAISER.

Comment (Development): MINE OPERATED BY BAXTER FROM 1928 TO 1951. FROM 1952 TO 1957 MINE OPERATED BY KAISER ALUMINUM AND CHEMICAL CORP. MINE HAS BEEN IDLE SINCE 1957, BUT THE PRINCIPAL CLAIMS WERE RELOCATED IN 1970 BY HOWARD TURLEY, THE PRESENT OWNER.

Comment (Production): 50,869 TONS FROM 1928-51 BY BAXTER; 131,028 TONS AVERAGING ABOUT 46% CA F2 FROM 1952-57 BY KAISER. TOTAL MINE PRODUCTION 181,897 TONS.
