The Crystal Fluorspar Mine is a fluorine-fluorite mine located in Jackson county, Colorado at an elevation of 9,406 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 (Reserve-Resource): NO PUBLISHED OZARK-MAHONING RESERVE DATA COULD BE FOUND AT THE TIME OF THIS 1982 MAS PROPERTY EVALUATION.
Comment (Production): ACTUAL RECOVERIES FOR THE ACID GRADE FLUORSPAR CONCENTRATE (PA) AND THE BRIQUETTES (PB) ARE 44.5 AND 43.6 PERCENT, RESPECTIVELY, FOR THE FLOURSPAR. ACTUAL SIO2 ORE-TO-CONCENTRATE RECOVERY FOR CONCENTRATE-TO- BRIQUETTE RECOVERY IS 0.306 PERCENT. SIO2 IS EXPECTED TO INCREASE FROM THE FLUORSPAR CONCENTRATE TO THE BRIQUETTES BECAUSE OF IMPURITY SIO2 CONTAINED IN THE CA(OH)2 ADDED AS ONE OF THE BRIQUETTE BINDER MATERIALS.
Comment (Deposit): THE FIRST COMPLETE INTERMOUNTAIN FIELD OPERATION CENTER (IFOC) EVALUATION OF THIS PROPERTY WAS COMPLETED DURING 1982. NO IFOC INSPECTION OF THIS FACILITY WAS MADE PRIOR TO OR DURING THIS EVALUATION.
Comment (Geology): THE MAIN VEIN AT ITS SOUTHERN END STRIKES N25-35W AND DIPS 54SW. THIS SEGMENT OF THE VEIN IS 305 M LONG, AND IT INTERSECTS AN ADJOINING FAULT WHICH IT FOLLOWS ALONG A BEARING OF N5W, DIPPING 63W FOR ANOTHER 610 M. TOTAL VEIN LENGTH, THEREFORE, IS ABOUT 915 M. VEIN THICKNESS IS HIGHLY VARIABLE, RANGING FORM A MAXIMUN OF 3.6 M TO A COMPLETE PINCHOUT LOCALLY. IN ADDITION TO PRE-CAMBRIAN FAULTING, FAULTING ALSO IS EVIDENT FROM LARAMIDE AND MIDDLE TO LATE TERTIARY.
