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 (Reserve-Resource): MATRIX ONE DATA IS FROM GARRANDS REPORT, BASED ON: LOWER VALLEY QUAD X-SECS 19F-22F, 23F-25F JOHNSON CREEK QUAD X-SECS 52E DRY VALLEY QUAD X-SECS 1A-3A M2C2 IS DERIVED BY SUBTRACTING M2C3(CALDWELL CANYON SITE- SEQ NO. 0160290162) FROM M1C2(SEQ # 0160290043). THIS WAS DONE BECAUSE CALDWELL CANYON (FROM EIS) IS A PART OF THE LARGER NORTH SCHMID RIDGE, WEST SLOPE DEPOSIT M2C1 IS DERIVED BY SUBTRACTING M3C3(SEQ NO. 0160290162) FROM M1C1(SEQ NO.0160290043). THIS WAS DONE CALDWELL CANYON IS PART OF THE LARGER NORTH SCHMID RIDGE, WEST SLOPE DEPOSIT
Comment (Deposit): ADDITIONAL 7.5MIN. MAPS NEEDED ARE JOHNSON CREEK, DRY VALLEY LEACHING OF CALCIUM RESULTS IN GREATER P2O5 PERCENTAGE. AREAS A,E,F, REFER TO PHOSPHATE STUDY BY GARRAND CORP. MUCH OF THE DEPOSIT IS UNDER LEASE, PART IS NOT.
