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.

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 SURFACE UNPUBLISHED REPORT IN PREPARATION BY J.B. CATHCART HAS BEEN USED FOR THIS COMPLETION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.
