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 (Development): OWNERS INCLUDED THE ARIZONA COPPER CO LTD.

Comment (Deposit): DISSEMINATED PYRITE IN SERICITIZED PORPHYRY IS EITHER PARTLY OR WHOLLY REPLACED BY CHALCOCITE. LIMESTONES CONTAIN VERTICAL SEAMS OF PYRITE.
