Pattuck Mine


It was worked continuously by the operators from May 1943 to May 1945. Mining began at pit A, but this working was abandoned during the summer of 1943. The pit is 40 feet long, 10 to 15 feet wide, and 5 to 20 feet deep. The deepest part, near the southwest end, is flooded with 10 to 12 feet of water and is partly backfilled. Pit B is an irregular open pit leading to an inclined open stope that is also partly backfilled. The open pit is about 90 feet long, 12 to 25 feet wide, and 5 to 35 feet deep. The open stope is 8 to 10 feet high and 6 to 8 feet wide and extends along the hanging wall about 20 feet beyond the headwall of the pit. Other prospect pits have been made southwest and northeast of pit B. From May 1943 to May 1945 about 2000 tons of rock was removed from pit Band about 500 tons from pit A. The average yield of mine-run mica was approximately 3.3 percent.
