Searles Lake Deposit

The Searles Lake Deposit is a sodium, salt, potassium, and boron-borates mine located in San Bernardino county, California at an elevation of 1,640 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.

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: Mixed
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 (Production): INVESTMENT OF $200 MILLION FOR CONSTRUCTION OF ARGUS PLANT AND RENOVATION OF TRONA AND WESTEND PLANTS.

Comment (Geology): A NEARLY DRY PLAYA LAKE COVERING ABOUT 100SQ KM, LENGTH 15KM WIDTH 11KM. THICKNESS OF FILL FROM 0 AT PERIPHERY TO OVER 900M TOWARD CENTER. BASEMENT ROCK QUARTZ MONZONITE. EVAPORITE DEPOSIT ALTERNATING MUD BEDS AND BRINE SATURATED SALT BEDS. 6 MAJOR LAYERS (BOTTOM-TOP): MIXED LAYER, BOTTOM MUD, LOWER STRUCTURE BRINE, PARTING MUD, UPPER STRUCTURE BRINE, OVERBURDEN MUD. IN DATA BASE, DEPTH TO MINERALIZED ZONE FOR OVERBURDEN MUD TO UPPER STRUCTURE. UNCONSOLIDATED MATERIAL SAME AS DEPTH TO MINERALIZED ZONE. THICKNESS OF MINERALIZATION COMBINED FOR THE UPPER AND LOWER STRUCTURE, IT DOES NOT INCLUDE THE MIXED LAYER, WHICH HAS A THICKNESS OF +200M. SINCE IT IS A DRY PLAYA LAKE, THERE IS NO STRIKE OR DIP. NO DEFORMATION HAS OCCURRED IN THE BRINES- ENTERED AS UNKNOWN UNDER RELATIONSHIP AND DEFORMATION, NO AGE GIVEN FOR AGE OF DEFORMATION.

Comment (Deposit): BRINE PUMPED FROM LAKE TO 1 OF 3 PLANTS. TRONA PLANT: EVAPORATION, FRACTIONAL CRYSTALLIZATION, SOL- VENT EXTRACTION, CALCINATION-- PRODUCES POTASH, BORAX, SALT CAKE. ARGUS PLANT: CARBONATION, CRYSTALLIZATION, CALCINATION-- PRODUCES SODA ASH. WESTEND PLANT: CALCINATION, EVAPORATION, FRACTIONAL CRYSTALLIZATION-- PRODUCES SODA ASH, SALT CAKE, BORAX. COMBINED PRODUCTION FROM 3 PLANTS: POTASH- 496MT/D, BORAX- 559MT/D, SODA ASH- 3230MT/D, SALT CAKE- 1616MT/D, TOTAL- 5901MT/D. BECAUSE THIS OPERATION DOES NOT FIT MANY OF THE CATEGORIES IN THE DATA BASE, ENTRIES HAVE BEEN SIMPLIFIED. PRODUCTION IS LISTED AS A COMBINED TOTAL FROM THE 3 PLANTS, AND COSTS ARE ALSO COMBINED TOTALS FOR THE 3 PLANTS. LI038 PUT ON MILS FOR ISMI ID NUMBER. WO116 IS SECOND ID NO. UGSG-MRDS/GSC LISTS A LAT/LONG OF N354500/W1172000 FOR THE ID AS LISTED IN MILS. LIST IS AS OF JUNE 94, CHECK IN AUG 95.

Comment (Ownership): KERR-MCGEE IS 100PCT OWNER OF ALL 3 PLANTS AT SEARLES LAKE. KERR-MCGEE ALSO OWNS 30PCT OF THE 8823HA IT OPERATES ON THE LAKE. THE OTHER 70PCT IS LEASED FROM THE U.S. GOVERN- MENT, AND KERR-MCGEE PAYS A ROYALTY ON PRODUCTION FROM THIS LEASED LAND.

Comment (Geology): Searles Lake deposit [also known as Trona deposit] [includes West End Chemical mine, McGee mine] - Searles Lake near Trona. aphthitalite, borax, burkeite, galeite, gaylussite, halite, hanksite, mirabilite, nahcolite, northupite, pirssonite, schairerite, searlesite, sulphohalite, teepleite, thenardite, tincalconite, trona, tychite.

Comment (Geology): OTHER MINERALS FOUND IN SEARLES LAKE NOT LISTED IN TABLE V IN THE DATA BASE: BURKEITE, GLASERITE, HANKSITE, NAHCOLITE NORTHUPITE, PIRSSONITE, SULFOHALITE, THENARDITE, TYCHITE.

Comment (Reserve-Resource): QUANTITY GIVEN IS TOTAL AMOUNT OF POTASH, BORAX, SODA ASH, AND SALT CAKE. BY COMMODITY, THE QUANTITY PRESENT IS: POTASSIUM CHLORIDE (POTASH)- 101.3MILLION TONNES SODIUM TETRABORATE (BORAX)-- 47.2MILLION TONNES SODIUM CARBONATE (SODA ASH)- 851.8MILLION TONNES SODIUM SULFATE (SALT CAKE)-- 488.1MILLION TONNES THE ASSAY IS THE PERCENTAGE OF EACH COMMODITY IN THE TOTAL RESOURCE.

Comment (Reserve-Resource): NOT A TUNGSTEN PRODUCER; U.S. BUR. MINES CIRCULAR 8315. BRINE CONTAINS 56 PPM TUNGSTEN. TOTAL 135 MILLION POUNDS OF TUNGSTEN
