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.

DURING JAN-JULY, 1991, THE SX PLANT WAS RUNNING 7,192 L/MIN AT A FEED GRADE OF 1.124 G/L CU FROM PREGNANT LEACH SOLUTION OFF OF OLD HEAP PILE. IN AUG 1991, THE SX PLANT (K2) WAS EXPANDED WITH ADDITION OF 2 NEW MIXER-SETTLERS TO ALLOW 2 PARALLEL TRAINS, EACH CONSISTING OF 1 STRIPPER AND 2 EXTRACTORS. FEED RATE WILL INCREASE TO 8,706 L/MIN. WHEN BURRO PIT ORE IS LEACHED. FEED GRADE INCREASES TO 1.4 G/L. LAT-LONG FOR ORIGIN (MINE) PERTAINS TO LOCATION OF COPPER CHIEF/DIABASE PIT. THIS LOCATION USED FOR THIS RECORD, BECAUSE MOST OF MINING ACTIVITY WILL BE AT THAT PIT RATHER THAN BURRO PIT.
