Smokey Canyon Mine

The Smokey Canyon Mine is a phosphorus-phosphates mine located in Caribou county, Idaho at an elevation of 7,697 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: National Forest
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): STRIKE & DIP OF MATRIX 2 (WEST LIMB OF ANTICLINE) AT 50 PERCENT LEVEL EQUALS N00W AND 20 DEGREES WEST. STRIKE & DIP OF MATRIX 3 (EAST LIMB OF ANTICLINE) AT 50 PERCENT LEVEL EQUALS N30W AND 45 DEGREES EAST. AVERAGE WIDTH OF MINERALIZATION (G-AWM) FOR MATRIX 1 COL 1 IS ESTIMATED AND NOT FROM COMPANY PROPOSED PIT DIMENSIONS. AVERAGE THICKNESS OF MINERALIZED ZONE (G-AWM) IS A CUMULA- TIVE FIGURE REPRESENTING MINABLE PHOSPHATE STRATA AND DOES NOT INCLUDE INTERVENING STRATA OF WASTE. IN MATRICES 2 AND 3 COLUMNS 1,2, AND 3, G-AWM WAS LEFT BLANK. G-AWM IS VARIABLE IN THESE COLUMNS AS ONE GOES FROM P-50 TO P-10 PERCENT QUANTITY LEVELS. P-50 QUANTITY LEVEL REPRESENTS THE SITUATION OF THE MINERALIZED STRATA CONTINUING TO A DOWNDIP DEPTH OF 250 M AT THE AVERAGE SURFACE DIP ANGLE. P-25 PERCENT QUANTITY LEVEL DEPICTS THE RESOURCE POSSIBLE IF THE STRATA WERE HORIZONTAL TO THE LEASE BOUNDARY. P-10 PERCENT QUANTITY LEVEL DEPICTS THE RESOURCE POSSIBIL- ITY IF THE STRATA ATTITUDE WAS 45 DEGREES IN DIP EXTEND- ING TO THE LEASE BOUNDARY. THE BOULDER CREEK ANTICLINE TRANSVERSES THE LEASE AREA. PHOSPHATE RESOURCES OCCUR ON BOTH LIMBS OF THE ANTICLINE AND WITHIN LEASE BOUNDARY.

Comment (Reserve-Resource): NEWLY DEVELOPED MINE WHICH REPLACED CONDA MINE. 30 YEAR MINE LIFE REPORTED IN RANDOL 93/94. PRODUCING 1,100,000 ST/YR AS OF 3-93. ESTIMATED MINE LIFE 12 YEARS PER BLM PHOSPHATE SPECIALIST AS OF 3-93. TRYING TO ADD RESERVES.
