Sundown Mine

The Sundown Mine is a lead, zinc, copper, and manganese mine located in Beaver county, Utah at an elevation of 5,246 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 (Location): SECTION SUBDIVISIONS SE 1/4, NW 1/4, NW 1/4, SEC 22.

Comment (Development): SUNDOWN # 1 IS AN ADIT IN THE LOWER WORKINGS, SUNDOWN # 2 IS AN INCLINE SHAFT THAT DIPS 85 DEG WEST & IS 150 FT DEEP

Comment (Workings): SURFACE AREA DISTURBED: 12 ACRES INCLINE SHAFT N 16 DEG W AT 69 DEG NW IS 52 FT DEEP. SHAFT IS NOT CONNECTED WITH UNDERGROUND WORKINGS.

Comment (Geology): THE QUARTZITE BEING MINED IN THE ADIT IS A HIGHLY SILICIOUS ROCK THAT IS HIGHLY OXIDIZED. THE INCLINE SHAFT FOLLOWS A VEIN THAT IS SLIGHTLY COPPER STAINED. THE DUMPS SHOW NO APPRECIABLE ORE.
