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 (Workings): TOTAL WORKINGS ON EVERGREEN MOUNTAIN INCLUDE SEVEN ADITS AND TWO SHAFTS AS SHOWN ON MAP PROVIDED BY JAMES, 1979. NO DESCRIPTION OF WORKINGS GIVEN. ONE SHAFT AND TWO ADITS WERE FOUND IN THE FIELD. THREE ADITS WERE INACCESSIBLE. ALL WORKING WERE LESS THAN 50 FEET IN LENGTH

Comment (Geology): DEPOSITS LOCATED IN A LIMESTONE GAP BETWEEN THE ALTA AND CLAYTON PEAK STOCK. MINERALIZATION CONFINED TO AREAS OF SKARN DEVELOPMENT AND SHOWS BOTH BEDDING AND STRUCTURAL CONTROL. BEDDING IS AT N90E, 50N

Comment (Location): INCLUDED WITH THIS NAMED PROSPECT ARE A GROUP OF UNNAMED ADITS AND SHAFTS LOCATED ON MT. EVERGREEN BETWEEN LAKE SOLITUDE AND TWIN LAKES RESERVOIR. SEVEN ADITS AND TWO SHAFTS ARE PRESENT. ; INFO FROM LAND.ST :1983

Comment (Deposit): DEPOSITS LOCATED IN LIMESTONE BETWEEN THE ALTA STOCK AND A SATELLITE OF THE CLAYTON PEAK STOCK. ALL DEPOSITS SHOW SKARN-TYPE METASOMATISM. SEVERAL OF THE PROSPECTS SHOW BOTH A STRATIGRAPHIC AND STRUCTURAL CONTROL OF MINERALIZATION. MINERALIZATION IS CHALCOPYRITE, MALACHITE, AND AZURITE WITH ASSOCIATED MAGNETITE HOSTED BY SKARNS

Comment (Deposit): Discovery Year: LATE 1800'S
