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 (Geology): THE GOLD KEY MINE IS IN ADESITES OF THE MIDNIGHT PEAK FORMATION, WHICH ARE INTRUDED BY THE CRETACEOUS FAWN PEAK STOCK. THE STOCK IS PROBABLY THE INTRUSIVE EQUIVALENT OF THE VOLCANIC ROCKS (STOFFEL AND MCGRODER, 1990, P. 15).
