The Green Crystal Mine is a fluorine-fluorite mine located in Juab county, Utah at an elevation of 5,899 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): THE ORE PIPE IS OVAL IN PLAN AND IS 43 FT LONG BY 18 FT. WIDE. IT APPEARS TO PLUNGE STEEPLY IN AN EAST-SE DIRECTION. THE ORE IS GENERALLY PALE-DARK PURPLE & OCCURRS MAINLY AS BOXWORK.
Comment (Workings): 35 FT. DEEP
Comment (Geology): STRATA STRIKES N40E DIPS 30NW
Comment (Location): SECTION SUBDIVISIONS SE 1/4 SE 1/4 SW 1/4
Comment (Development): RECENT URANIUM EXPLOR. INDICATES A FAIR U3O8 CONTENT (UP TO 0.15-0.20%), BUT IT OCCURS IN COMPLEX STRUCTURE WITH F IONS WHICH MAKES IT ECONOMICALLY MARGINAL FOR EXTRACTION
Comment (Commodity): CHIEF IMPURITIES ARE MONTMORILLONITE, CREAM COLORED DOLOMITE & QUARTZ
