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 (Development): SEE COMMENTS FOR GOODYEAR PROSPECT

Comment (Deposit): LENTICULAR, FAULT BOUNDED ORE BODY 30 FT LONG AND 5 FT WIDE CONTAINS IMPREGNATIONS OF COPPER SULPHIDES AND IS CUT BY 8 TO 12 IN FAULTED CALCITE VEIN CARRYING CHALCOPYRITE AND BORNITE; PROBABLY FAULTED-OUT SECTION OF GOODYEAR VEIN

Comment (Workings): EXPLORED BY OPEN CUT, AS EARLY AS 1902

Comment (Geology): SEE COMMENTS FOR GOODYEAR PROSPECT; SIMILARITY IN CHARACTER OF ORE BODIES AT HENRY PRATHER AND GOODYEAR INDICATES THAT THEY ARE PROBABLY FAULTED SECTIONS OF THE SAME ORE MASS
