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 (Production): $40,000 IN GOLD WAS PRODUCED IN 1940-41 (HUNTTING, 1956, P. 144).

Comment (Deposit): THE QUARTZ VEINS THAT MAKE UP THE DEPOSIT WERE DEVELOPED BY SEVERAL SHAFTS AND ADITS. MORE THAN 2200 FEET OF UNDERGROUND WORKINGS WERE PRESENT; MORE THAN HALF OF THESE WERE WEST OF THE METHOW RIVER (HUNTTING, 1956, P. 144). ; INFO.SRC : 1 PUB LIT

Comment (Geology): THESE VEINS ARE IN BASIC DIKES OF PROBABLY EOCENE AGE AND WHICH CUT THE CRETACEOUS METHOW GNEISS (BUNNING, 1990; CULVER AND BROUGHTON, 1945).
