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 (Deposit): A GOLD-QUARTZ-CALCITE VEINS OCCURS ALONG FAULTS IN SILURIAN GREENSCHIST THE VEINS ROUGHLY PARALLEL A LIMESTONE-GREENSCHIST CONTACT TO THE SOUTHWEST OF THE PROSPECT (BREW, AND OTHERS, 1984). TWO STEEPLY DIPPING VEINS ARE EXPOSED, THE LONGER OF WHICH EXTENDS FOR ABOUT 500 FEET WITH A MAXIMUM THICKNESS OF ABOUT 3 FEET (MAAS, BITTENBENDER, AND STILL,1995). VISIBLE GOLD IS PRESENT IN THE VEINS BUT APPARENTLY THERE ARE FEW OTHER ORE MINERALS PRESENT. THE GOLD VALUES ARE ERRATIC. SAMPLING SHOWED GOLD VALUES UP TO 2,027 PPM (59.0 OUNCES PER TON) BUT MOST VALUES WERE LOWER, AND SILVER VALUES ONLY REACHED A MAXIMUM OF 50.0 PPM.

Comment (Reserve-Resource): IN VIEW OF THE LIMITED AMOUNT OF DATA, RESERVE CALCULATIONS WERE CONSIDERED UNWARRANTED BY MAAS, BITTENBENDER, AND STILL, (1995) WHO SAMPLED THE PROPERTY.

Comment (Location): THE DUMP ON THIS PROSPECT IS LESS THAN 100 FEET FROM THE SHORELINE ON EL CAPITAN PASSAGE, JUST NORTH OF THE MOUTH OF TOKHINI CREEK, NORTHEAST KOSCIUSKO ISLAND. LOCATED TO WITHIN 100 FEET IN SECTION 23, T. 66 S., R. 78 E.

Comment (Workings): MASS, BITTENBENDER, AND STILL (1995) STATE THAT THE DEPOSIT WAS ORIGINALLY FOUND IN 1962 BUT THE CLAIMS ALLOWED TO LAPSE; THE PROPERTY WAS RESTAKED IN 1967. IT HAS BEEN ACTIVE SINCE. PROPERTY DEVELOPED BY EIGHT TRENCHES AND A SHORT ADIT. A MINERAL SURVEY HAS BEEN DONE ON THE PROPERTY WITH INTENT TO PATENT IT. A MAP OF THE PROPERTY IS IN MAAS, BITTENBENDER, AND STILL (1995).

Comment (Production): PROBABLY NONE.

Comment (Exploration): Status = Active
