The Fluoride #18 Mine is a fluorine-fluorite mine located in Juab county, Utah at an elevation of 5,781 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 (Deposit): DEPOSIT CONSISTS OF 2 VERTICAL PIPES. STRATA STRIKES N35E & DIPS 34 NW. THE MAIN ORE PIPE CROPS OUT AT THE SURFACE & IS OVAL SHAPED. THE 2ND PIPE DOES NOT CROP OUT AT THE SURFACE & WAS STOPED FROM ADIT
Comment (Workings): A 70 FT ADIT, 2 RAISES & A WINZE
Comment (Geology): STRATA STRIKES N35E & DIPS 34 DEG. NW. A FAULT STRIKES N45-55W & DIPS 72SW WHICH BRINGS FISH HAVEN & SWAN PEAK IN CONTACT
Comment (Reserve-Resource): ORE POTENTIAL IS LESS THAN 200 TONS IN 1976.
Comment (Location): SECTION SUBDIVISIONS SE 1/4 NE 1/4 SE 1/4
Comment (Development): RECENT URANIUM EXPLOR INDICATES A FAIR U3O8 CONTENT (UP TO 0.15-0.20%), BUT IT OCCURRS IN COMPLEX STRUCTURE WITH F IONS WHICH MAKES IT ECONOMICALLY MARGINAL FOR EXTRACTION
Comment (Commodity): CHIEF IMPURITIES ARE MONTMORILLONITE, CREAM COLORED DOLOMITE & QUARTZ
