Paris-Bloomington Deposits

The Paris-Bloomington Deposits is a phosphorus-phosphates mine located in Bear Lake county, Idaho at an elevation of 6,503 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.

THE BEDS HAVE BEEN FOLDED INTO A LARGE SYNCLINE, THE WEST LIMB OVER NED TO AN ANGLE OF 30-85 DEGREES, AND THE NORMAL LIMB HAVING AN AVG DIP OF 20 DEGREES IN 1944 A STUDY OF THE AREA BY HOMESTAKE FOR MINING STATES "THE V205 BEDS ARE SOFT AND EASILY MINED. THE WALLS ARE WEAK, REQUIRING TIMBERING WITH CAVING CLOSELY FOLLOWING MINING TOP SLICING IS RECOMMEND FOR EXTRACTION OF THE OVERTURNED LIMB AND A LONG WALL METHOD FOR THE NORMAL CLIMB, REMOVING THE ORE WITH SCRAPERS."

LEASES OR PERMIT THE ORE IS SEVERAL LARGE BLOCKS BY GEOLOGIC FAULTS. THE ATTITUDE & ELEV OF THE VARIOUS BLOCKS ARE DIFFERENT ENOUGH TO WARRANT A MINING PLAN TAILORED TO EACH BLOCK BLOCKS WILL BE DEVELOPED BY DRIVING A CONVEYOR ADIT DOWN THE MIDDLE OF THE BLOCK FROM SURFACE. THE FLOOR OF THIS ADIT WILL BE AT THE BASE OF THE V205 RICH ZONE. A VENT RAISE AT THE END OF THE ADIT WILL FUNCTION AS AN EXHAUST RAISE THEN STARTING NEAR THE PORTAL A PERIPHERAL DRIFT WILL LOOP AROUND ONE EDGE OF THE ORE BODY, CONNECTING UP WITH THE VENTILATION RAISE. AS SOON AS THE PERIPHERAL DRIFT IS DRIVEN AN AIRLOCK WILL BE INSTALLED TO DIRECT 45,000 CU. FT. OF FRESH AIR PER MINUTE INTO EACH OPENING ROOM AND PILLAR EXTRACTION WILL START IN THE FAR CORNER OF THE BLOCK AND RETREAT TOWARDS THE CONVEYOR ADIT. 25% OF
