The Bishop Cap Hills Area is a fluorine-fluorite mine located in Dona Ana county, New Mexico at an elevation of 4,600 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 (Workings): THREE SMALL ADITS AND SEVERAL PROSPECT PITS AND TRENCHES. UNDERGROUND WORKINGS TOTAL 170 FT IN LENGTH.
Comment (Geology): MINERALIZATION IS LARGELY CONTROLLED BY A LARGE CURVED, GENERALLY E-W TRENDING NORMAL FAULT KNOWN AS THE BLUE STAR FAULT. MINERALIZATION MAY BE RELATED TO THE ORGAN MOUNTAIN QUARTZ MONZONITE STOCK TO THE NORTH.
Comment (Deposit): THE MINERALIZATION IS LOCALIZED IN FISSURE VEINS ALONG FAULTS AND FRACTURES AND IN IRREGULARLY SHAPED JASPEROIDAL REPLACEMENTS IN BRECCIATED ZONES ALONG FRACTURES AND BEDDING PLANE FAULTS. MINERALIZATION IS WIDESPREAD THROUGHOUT THE PALEOZOIC CARBONATE SECTION.
