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 (Geology): SERPENTINE (MINERAL NAME)

Comment (Reserve-Resource): INTERSTRAT RESOURCES, INC., OF VANCOUVER, B.C., AND A 50 PERCENT OWNER OF PINE FLAT IS PRESENTLY BEING ACQUIRED BY FRONTIER INTERNATIONAL GROUP OF CALBURN, TX, A SUBURB OF DALLAS. THIS IS A DIVERSIFIED COMPANY WITH LAND HOLDINGS SUITABLE FOR DEVELOPMENT NEAR CHANDLER, AZ, 47 OIL AND GAS WELLS, AND A 20 PERCENT OWNERSHIP OF LUNDBERG MINES, A POTASH PRODUCER IN CARLSBAD, NM, AMONG OTHERS. THE PRESIDENT OF THIS COMPANY IS MR. MICHAEL PATMAN. IN 1986, INTERSTRAT COMPLETED THE FIRST PART OF A FEASIBILITY STUDY WITH ASSISTANCE BY DAVY MCGEE CORP. THAT RECOMMENDS DEVELOPMENT OF THE PROPERTY. COST WOULD BE ALMOST $260 MILLION. THERE WOULD BE A 2,270 T/DAY MINE PRODUCING 32,700 T/Y MAGNESIUM, 6,350 T/Y NICKEL, AND 900 T/Y COBALT. MINE LIFE IS EST. TO BE 13 YEARS WITH EMPLOYMENT OF 300. THE SECOND PART OF THIS STUDY SHOULD BE INSTIGATED SOON AFTER FRONTIER COMPLETES ITS ACQUISITION.

Comment (General): Is this the same thing as the Gasquet Mountain deposit (Dep_ID 10284620)? Look at statement in Comments, Reserve-Resource line 4.
