Gird Creek Prospect

The Gird Creek Prospect is a phosphorus-phosphates mine located in Granite county, Montana at an elevation of 6,401 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.

Comment (Deposit): 480 ACRES OF US LEASE HELD BY MONTANA PHOSPHATE PRODUCTS CO. BEDDS ON BOTH LIMBS OF THE DOUGLAS CREEK ANTICLINE. WEST LIMB: RETORT MEMBER; STRIKES N10W DIPS 85SW, BED IS 1.4 FT THICK AT 34% P205, 4.35 FT THICK AT 27.1% P205 AND 8.85 FT THICK AT 21.5% P205. LIMB EXPLORED BY 243 FT LING ADIT. EAST LIMB: RETORT MEMBER: STRIKES W-S DIPS 63NW; BED IS 3.55 FT THICK AT 31.3% P205, 7.7 FT THICK AT 24.4% P205 LIMB EXPLORED BY 130 FT LONG ADIT. HANGING AND FOOTWALLS ARE QUARTZITE. THICKNESS AND GRADE AND MINING CONDITIONS ARE SIMILAR TO THOSE OF THE DOUGLASS CREEK MINE. ADITS DRIVEN FROM NEAR CREEK LEVEL WOULD PROVIDE BACKS OF 700 FT ON THE EAST LIMB AND 300 FT ON THE WEST LIMB. INFERRED TONNAGE IN BOTH LIMBS IS 8350000 ST OF FERTILIZER GRADE(5000 FT LONG, 30 INCHS WIDE, AND 300-700 FT DEEP) SAMPLE LOT 1399 FROM USGS PROF. PAPER 313-F IS LOCATED HERE.
