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: Federal
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 (Deposit): THE FIRST COMPLETE INTERMOUNTAIN FIELD OPERATION CENTER (IFOC) EVALUATION OF THIS PROPERTY WAS COMPLETED DURING 1982. NO INSPECTION OF THIS FACILITY WAS MADE PRIOR TO OR DURING THIS EVALUATION.

Comment (Workings): RAW WATER IS PUMPED TO THE FLUORSPAR VEIN PROPERTIES AND THE ADJOINING NORTHGATE MILL FROM TWO SOURCES: (1) A 15 CENTIMETER DIAMETER, 1830 METER WATER LINE BRINGS WATER FROM PINKHAM CREEK WHICH IS SOUTH OF THE PROPERTY. THIS LINE HAS A 10 CENTIMETER BACK-UP LINE. (2) A 20 CENTIMETER LINE BRINGS WATER 5490 METERS FROM THE NORTH PLATTE RIVER. CLAIM PATENT DESCRIPTIONS DESCRIBE THE MINING DISTRICT AS THAT OF COPPER RIDGE, A NAME FORMERLY APPLIED TO A LARGE, INDEFINITE AREA IN NORTHERN COLORADO AND SOUTHERN WYOMING. THIS NAME HAS BEEN DROPPED FROM LOCAL USAGE, AND THE MORE RESTRICTED AREA IN THE VICINITY OF THE FLUORSPAR DEPOSITS NOW IS CALLED THE NORTHGATE DISTRICT, AFTER THE SHIPPING POINT OF NORTHGATE ON THE UNION PACIFIC RAILROAD.

Comment (Reserve-Resource): NO PUBLISHED OZARK-MAHONING RESERVE DATA COULD BE FOUND AT THE TIME OF THIS 1982 MAS PROPERTY EVALUATION. There are no reported reserves.

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 MATERI- ALS.

Comment (Identification): The Fluorspar Vein properties includes the Gero and Penber Mines, and the Springer Pit.
