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 (Production): MINED OUT. THE PRESENT ACCESS ROAD IS ADEQUATE. WATER AND ELECTRICAL POWER ARE AVAILABLE AT THE SITE. POSSIBLY THE SAME MINE AS SEQ# 0160290015 WOOLEY VALLEY MINE.

Comment (Development): NON-GEOLOGIC CONSTRAINTS ON DEVELOPMENT OR EXPANSION IN 1-5 YRS. (). DEVELOPMENT(UNKNOWN); EXPLORATION(UNKNOWN); RUN OF MINE ORE 18-24 % P2O5 (39.3-52.4 % BPL), THE ORE IS RAISED TO 24-28 % P2O5 (52.4-61.1 % BPL)

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 PHOSPHATE CONCENTRATE THE RUN OF MINE ORE GRADES 19-23 % P2O5. PART OF THE OUTPUT IS UP-GRADED TO 30 % P2O5 BY WASHING. SOME OF UPGRADED PRODUCT IS THEN MIXED WITH UNWASHED MATRIX TO PROVIDE A 25 % P2O5 (54.6 % BPL) MATERIAL.

Comment (Development): 2 LEASES TOTAL 760 ACRES ( 1966 ) ; ECON.COM: RESERVES WILL BE DEPLETED BY 1982 ( USGS, 1975 )
