Cyprus Johnson Camp

The Cyprus Johnson Camp is a copper mine located in Cochise county, Arizona at an elevation of 5,000 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Land Status

Land ownership: BLM Administrative Area
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.

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.
