Comment (Geology): QUADRANT QUARTZITES AT THIS LOCATION STRIKE N 35 DEG E AND DIP 42 DEG SE AS PART OF EAST LIMB OF N TRENDING ANTICLINE
Comment (Deposit): ORE DEPOSITION PROBABLY OCCURRED IN MORE THAN TWO STAGES. THOSE DEPOSITS WITH EXTENSIVE TOURMALINE PROBABLY FORMED AT HIGH TEMPERATURES.
Comment (Location): 15 OR MORE MINES WITHIN THE DISTRICT ; INFO FROM LAND.ST :(1954)
Comment (Production): ITEM 17 FROM AN ESTIMATE OF 30000 CUBIC YDS OF EARTH. ITEM 23 FROM 38919 TONS OF ORE. LIMESTONE HAS BEEN QUARRIED. AROUND 1900 THE SEASONAL OUTPUT OF LIME IS REPORTED TO BE 125000 BUSHELS OF 80 POUNDS.
