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): AT HEADWATERS OF ROCK CREEK ON WEST SLOPE OF SILVER STAR MOUNTAIN AND NORTHEAST SLOPE OF LARCH MOUNTAIN. PROPERTY CONSISTS OF 1,040 ACRES
Comment (Reserve-Resource): ABOUT 2 TONS OF ORE IS ON THE DUMP
Comment (Development): FROM 1930-1944, NUMEROUS OPEN CUTS WERE DUG, 3 ADITS DRIVEN, SAMPLES COLLECTED AND ASSAYED, AND SEVERAL CORE HOLES DRILLED, BUT NO SHIPMENTS WERE MADE. PROPERTY IDLE IN 1977
Comment (Deposit): MINERALIZATION OCCURS IN TWO MAIN AND SEVERAL SMALLER NORTHWEST TRENDING, STEEPLY DIPPING FRACTURE ZONES IN ANDESITE. THE GOAT VEIN IS A QUARTZ-FILLED SHEAR ZONE, 1-18 FT THICK, THAT CAN BE TRACED FOR AT LEAST 3,000 FT. ORE MINERALS ARE DISSEMINATED WITHIN BRECCIATED ROCK. THE OXIDIZED VEIN IS IN SILICIFIED ANDESITE NEAR ITS CONTACT WITH THE SILVER STAR PLUTON.
Comment (Workings): 125-FT ADIT, 227-FT ADIT, OPEN CUTS
Comment (Geology): DEPOSIT IS NEAR THE CONTACT OF SILVER STAR PLUTON AND SKAMANIA VOLCANICS
Comment (Deposit): MAP OF PROSPECT AND LOCATION MAP AVAILABLE, MOEN, 1977 ; INFO.SRC : 1 PUB LIT
