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 (Development): LOCATED ABOUT 1897 BY OCEANIC MINING CO., LITTLE DEVELOPMENT FOR MANY YEARS, SOLD TO ALASKA COPPER MINING CO. IN 1920. VARIOUS CLAIMS LOCATED 1923-57. SMELTER-TEST SHIPMENT BEFORE 1925. RELOCATED AS 3 LUCKY STAR CLAIMS IN 1968, ACTIVE AS OF 1985.

Comment (Deposit): DISSEMINATED SULFIDES AND MASSIVE SULFIDE LENSES UP TO 1 FT. WIDE AND 3 FT. LONG PARALLEL TO FOLIATION IN CHLORITE PHYLLITE AND SCHIST. SULFIDES MOSTLY PYRITE AND SPHALERITE WITH LESSER AMOUNTS OF GALENA, CHALCOPYRITE, BORNITE, TETRAHEDRITE, SECONDARY CHALCOCITE AND COVELLITE, TRACES OF MALACHITE, NATIVE SILVER, AND GOLD. TWO ZONES OF MINERALIZATION, ONE IN VICINITY OF ADITS NO. 1 AND 2, THE OTHER TO THE NW IN VICINITY OF INCLINED AND VERITICAL SHAFTS, ARE SEPARATED BY 700 FT. OF BEACH BARREN OF MINERALIZATION. QUARTZ VEINS UP TO 20 FT. WIDE ARE COMPOSED OF QUARTZ STRINGERS UP TO SEVERAL IN. WIDE WITH INTERVENING SCHIST LAYERS. DISSEMINATED SULFIDES OCCUR IN THE SCHIST LAYERS.

Comment (Deposit): PROSPECT STAKED BY GEORGE SIEFFART AND KEN MANNING IN 1983, WITH WINKIE DRILLING AND BLASTING DONE IN 1984-85. ; INFO.SRC : 1 PUB LIT

Comment (Location): USGS B 1525, FIG. 24; USGS MF-425, LOC. 7. LOCATION IS AT ADIT NO. 1. WORKINGS AT PROSPECT EXTEND 1150 FT. NW AND 200 FT. SE FROM LOCATION, ALONG SHORE. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.
