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.

Comments

Comment (Production): PB, ZN, CU CONC. ASSAYS AND RECOVERIES ARE NOT ACTUAL BUT APPROXIMATE ESTIMATES.

Comment (Geology): SILVER IS ASSUMED TO BE PRESENT IN THE ORE IN SULFIDE FORM.

Comment (Economic Factors): THE MILL IS A CUSTOM MILL LOCATED IN DEMING, NEW MEXICO, 40 MILES AWAY FROM THE MINE. THE DESIGN CAPACITY OF THE CUSTOM MILL IS 750 TONS (680.4 MTON) PER DAY. ASSUMING THAT THIS MILL IS RUNNING AT 100- PERCENT CAPACITY, AN EXPANSION OF 250 TONS (226.8 MTON) PER DAY IS PROPOSED. DESIGN CAPACITY IN CONCENTRATOR DATA SET MEANS THE ADDED CAPACITY OF 226.8 MTON PER DAY. DEPOSIT PERCENT, 100 REFERS TO PROPOSED ADDITIONAL MILL CAPC.

Comment (Ownership): THE CUSTOM MILL, ALSO OWNED BY ASARCO, IS LOCATED IN DEMING, NEW MEXICO.

Comment (Economic Factors): THE MINING METHOD GIVEN INCLUDES CUT AND FILL IN VEINS AND IN ORE BODIES. LENGTH OF WORKING EQUAL TO 11,525 METERS INCLUDES AN ESTIMATE LENGTH OF 10,000 METER OF DRIFTS DRIVEN SINCE 1914. THE MINE SHUT DOWN OPERATIONS IN 1978.

Comment (Geology): THE LITHOLOGY AND ITS RELATION TO MINERALIZATION HAS NOT BEEN WELL DEFINED. BECAUSE OF THIS THE INFORMATION IN THE L DATA-SET IS INCOMPLETE.
