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 (Location): LIES ON THE SOUTH SLOPE OF CUDDY MOUNTAIN BETWEEN CAMP AND GRADE CREEKS.

Comment (Workings): WORKINGS ARE CAVED IN. ADITS IN THE CONGLOMERATE UNIT SUGGEST BETTER GRADE MINERALIZATION.

Comment (Geology): THE CAMP CREEK LATITE IS A PORPHYRITIC FLOW WITH PHENOCRYSTS OF ORTHOCLASE AND PLAGIOCLASE SET IN AN APHANITIC GROUND MASS.

Comment (Deposit): GRADE CREEK CONGLOMERATE IS PEBBLE TO COBBLE IN SIZE, WITH RED, PURPLE, AND GREEN CLASTS OF DOMINANTLY EXTRUSIVE ROCKS.
