The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): AT THE NORTH END OF RUBY HILL
Comment (Geology): THE VEIN IS IN GRANODIORITE OF CRETACEOUS AGE NEAR THE CONTACT WITH HORNBLENDE-BIOTITE SCHIST OF THE METAMORPHIC COMPLEX OF CONCONULLY (GULICK AND KOROSEC, 1990, GEOL. MAP).
Comment (Production): ORE WAS BLOCKED OUT BUT WAS NOT MINED BECAUSE OF THE SILVER PANIC OF 1883. IN 1920 THE MINE WAS REOPENED, AND ORE THAT AVERAGED 30 OZ/TON AG, 17% PB, AND 4% CU WAS SHIPPED TO A SMELTER AT BRADLEY, IDAHO. SMALL SHIPMENTS OF ORE WERE MADE AGAIN IN 1921 AND 1924 (MOEN, 1973, P. 18).
