The Champion Dumortierite Mine is a kyanite and aluminum mine located in Pershing county, Nevada at an elevation of 5,551 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.
Elevation: 5,551 Feet (1,692 Meters)

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.
Champion Dumortierite Mine MRDS details
Primary: Champion Dumortierite Mine
Secondary: Oreana Dumortierite Deposit

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.

Comment (Commodity): ONLY KNOWN COMMERCIAL DEPOSIT IN WORLD (JOHNSON).
Comment (Deposit): DUMORTIERITE OCCURS ALONG 2 NORTH-TRENDING ZONES OF HYDROTHERMALLY ALTERED QUARTZ-SERICITE RHYOLITE, PARTS OF WHICH WERE INTENSELY ALTERED DURING TWO PHASES WHICH FIRST PRODUCED THE ANDALUSITE, THEN THE DUMORTIERITE BY REPLACEMENT OF ANDALUSITE (ACCORDING TO KERR AND JENNEY, 1935). DUMORTIERITE OCCURS AS (1) COARSE EUHEDRAL BLUE CRYSTALS, (2) MATTED LAVENDAR OR PINK MASSES, AND (3) FIBROUS PINK VEINS OR ISOLATED PINK CRYSTALS. HAND-SIZED CHUNKS OF DUMORTIERITE WERE SO VALUABLE THAT THEY WERE COBBED AND SAVED. VEINLETS WERE NOT MINED BECAUSE OF EXCESSIVE CONTAMINATION OF QUARTZ AND ALBITE.
Comment (Workings): OPEN PIT, TUNNELS, OPEN STOPES.
Comment (Geology): DUMORTIERITE MINERALIZATION MAY BE RELATED TO PERMO-TRIASSIC VOLCANICS OR TERTIARY QUARTZ MONZONITE STOCK INTRUSION. LENSES OF DUMORTIERITE AND ANDALUSITE OCCUR IN QUARTZ-SERICITE SCHIST.
