West Fritz Prospect

The West Fritz Prospect is a scandium mine located in Utah county, Utah at an elevation of 6,079 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: Private
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 (Workings): WORKINGS CONSIST OF A SINGLE TRENCH ABOUT 100 FEET LONG, 35 FEET WIDE AND 20 FEET DEEP. APPEARS TO BE A FAIRLY MODERN CUT.

Comment (Geology): DEPOSIT OCCURS IN THE UPPER PART OF THE GREAT BLUE LIMESTONE, ABOVE THE LONG TRAIL SHALE MEMBER. DEPOSIT LIES ABOUT 2 MILES SOUTHEAST OF THE EAGLE HILL RHYOLITE, THE NEAREST IGNEOUS ROCK

Comment (Location): INFO FROM LAND.ST :(1977)

Comment (Development): SAMPLE TAGS PRESENT SUGGESTS THAT GOLD EXPLORATION TOOK PLACE IN THIS AREA
