The Bell Hill Mine is a fluorine-fluorite mine located in Juab county, Utah at an elevation of 5,249 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.

Comments
Comment (Deposit): THE MAIN ORE BODY (PIT #1) IS A PIPE IN THE SHAPE OF AN "H" AT THE SURFACE WHICH BECOMES MORE ELIPITICAL AT LOWER LEVELS. ABOUT 30 METERS EAST ANOTHER SMALL PIPE PLUNGES N74 DEG. E
Comment (Workings): THE PROPERTY WAS LEASED TO GEORGE SPOR IN 1950, WHO MINED F BY MEANS OF OPEN PIT FROM 2 ORE BODIES. FROM OCT. 1950-AUG. 1951 THE PROPERTY WAS UNDER CONTROL THE E.D. HARRIS FAMILY WHO DROVE A 230 FT ADIT FROM THE E. SIDE OF HILL.
Comment (Geology): THE DEPOSIT AT PIT #2 IS IN A FRACTURE ZONE OF THE FOOTWALL OF A NE-TRENDING FAULT WITH A TRUE DISPLACEMENT OF 53 M 4 OTHERS VEINS OF LESSER SIZE AND GRADE OCCUR NEARBY
Comment (Deposit): PIT #1 IS 49 M. LONG UP TO 15 M. WIDE & PLUNGES 52 DEG. N62 DEG. E ABOVE THE 26.5 M. LEVEL. PLUNGE IS 70 DEG. S81 DEG. E. BETWEEN THE 26.5 M-51 M. LEVELS. PIT #2 ORE BODY IS 14 M. LONG, 8.5 M. WIDE AND PLUNGES 65 DEG. S. 58 DEG. 6. 4 OTHER VEINS ARE LOCATED BUT UNMINED. ; INFO.SRC : 3 FIELD OBSERV
Comment (Development): RECENT URANIUM EXPLORATION INDICATES A FAIR URANIUM CONTENT IN COMPLEX STRUCTURE WITH FLORIDE IONS (0.15% EU3O8) BUT THE EXTRACTION & SEPARATION PROCESS IS NOT COST EFFICIENT
Comment (Reserve-Resource): ACCORDING TO R.G. WORL OF USGS (1971-UNPUBLISHED) THERE ARE 328,000 LT OF 40% CAF2 ORE AND LARGE, LOW GRADE BE & U ORE
Comment (Reserve-Resource): ACCORDING TO UNPUBLISHED DATA BY R.G. WORL (USGS) THE SPOR MTN. DISTRICT RESERVES ARE 328,000 MET. TONS OF 40% CAF2 ORE AND LARGE, LOW GRADE BE AND U DEPOSITS. (1971)
Comment (Location): SECTION SUBDIVISIONS SE 1/4 SE 1/4 SE 1/4
Comment (Production): PRODUCTIVE PERIOD WAS 1950 - 1956, 1960 - 1961.
Comment (Commodity): CHIEF IMPURITIES ARE MONTMORILLONITE, CREAM COLORED DOLOMITE & QUARTZ
