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.

Comments

Comment (Deposit): LEACHING OF CALCIUM RESULTS IN GREATER P2O5 PERCENTAGE. V205 RICH ZONE IS ON THE AV. 11 FT. THICK, THE TOP OF THIS ZONE IS 35 FT. BELOW THE BOTTOM OF THE REX CHERT MEMBER OF THE MEAD PK. MEMBER. THE V205 ZONE IS COMPOSED OF 3 LAYERS: SILTSTONE, OOLITE,& SHALE. SILTSTONE: AVG 5 FT. THICK, 11% CALCIUM PHOSPHATE, 24% OIL& WATER, S.G. 2.3 OOLITE: 55% CALCIUM PHOSPHATE, 12% OIL & WATER, S.G. 2.6 SHALE: 30% CALCIUM PHOSPHATE, 30% OIL & WATER, S.G. 2,16 THE AVG THICKNESS OF THE V205 BEDS IS 11 FT., & THEYg ARE BELIEVED TO UNDERLIE AN AREA OF 3 SQ. MILES. 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." EARTH SCIENCES PLANS TO MINE 1.5 MILL. TONS PER YR. OF PHOSPHATE ROCK FOR FERTILIZER & RECOVER SILVER & SELENIUM. THEY CONTROL 4000 ACRES, 540 OF THIS IS FED. 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

Comment (Workings): 17 ACRES WOULD BE DISTURBED BY MINING ACCORDING TO E.I.S. 3 ACRES FOR DUMPS,12 ACRES FOR ROADS,2 ACRES FOR OTHER USES. THIS IS FOR AN UNDERGROUND OPERATION

Comment (Geology): BANNOCK OVERTHRUST LIES 2000 FT. WEST OF PROPERTY ORE ZONE IS CUT BY SEVERAL TRANSERSE FAULTS (EAST-WEST STRIKE), & REVERSE FAULTS NEARLY PARRALLED TO THE BEDDING

Comment (Geology): V205 MINERALS ARE HEWETTITE & SINCOSITE. THE V205 BEDS IN PLACES CONTAIN NUMEROUS VEINLETS OF PYRITE & A FEW PRYITE CONCRETIONS
