The Maybe Canyon Phosphate Mine is a phosphorus-phosphates mine located in Caribou county, Idaho at an elevation of 6,919 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.

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.

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 (Location): ABOUT 32 KM EAST OF SODA SPRINGS, RAIL CONNECTION WITH THE FERTILIZER PLANT AT CONDA
Comment (Geology): 202.1 FT THICKNESS PHOSPHATIC SHALE MEMBER (SECTION 10 , T 8 S, R 44 E), 158.4 FT (SECTION 28 , T 7 S, R 44 E); THICKNESS ABOVE FOR 2 ORE ZONES. OVERBURDEN IS USUALLY SHALLOW, CONSISTING PRIMARILY OF WEATHERED CHERT, LIMESTONE, AND PHOSPHATE ROCK FLOAT.
Comment (Workings): PROPOSED MINE PIT WILL COVER 640 ACRES AND BE ABOUT 10,000 FT LONG, 700 FT WIDE, 250 FT DEEP
Comment (Deposit): LOCATED ON U.S. FOREST SERVICE LANDS. MAYBE CANYON MINED OUT. NORTH MAYBE CANYON EXTENSION MINE MAY START UP IN 1994 OR 1995.
Comment (Production): 1986 UPDATE. MINE DID NOT PRODUCE IN 1984. CONDA PARTNERSHIP HAS MOVED OPERATIONS TO CHAMP/MT. FUEL. PRODUCTION UNLIKELY IN FUTURE. EST. 1984 PRODUCTION: 2.7 MILLION T AT 25% P2O5.
Comment (Deposit): THIS RECORD WAS COMPILED FOR THE INTERNATIONAL STRATEGIC MINERALS INVENTORY. THE DATA WERE USED IN PREPARATION OF THE USGS CIRCULAR 930 SERIES OF REPORTS. MINERAL RESOURCE CATEGORIES AND CODES HEREIN ARE FROM THE INTERNATIONAL CLASSIFICATION SYSTEM RECOMMENDED BY THE UNITED NATIONS GROUP OF EXPERTS ON DEFINITIONS AND TERMINOLOGY FOR MINERAL RESOURCES. (SEE NATIONAL RESOURCES FORUM, V. 4, NO. 3, P. 307-313.). SURFACE UNPUBLISHED REPORT IN PREPARATION BY J.B. CATHCART HAS BEEN USED FOR THIS COMPLETION
Comment (Location): NORTH MAYBE CANYON MINE PLOTTED IN SECTION 4 , T 8 S, R 44 E ; THE PROPOSED SOUTH MAYBE CANYON MINE WOULD BE LOCATED IN SECTIONS 10 , 11 , 14 , 15 OF T 8 S, R 44 E
Comment (Development): PROPOSED MINE ON 1522.4 ACRE LEASE ( 1975 ) ; ECON.COM: FOR PROPOSED SOUTH MAYBE CANYON MINE, STRIPPING RATIO WOULD BE 1.8 : 1 (CY WASTE : TONS ORE)
Comment (Reserve-Resource): THE TONNAGE WAS OBTAINED FROM THE CONDA PARTNERSHIP. THE GRADE WAS ESTIMATED FROM CONDA PARTNERSHIP INFORMATION.
