Also known as the Miller Lake O'Brien Mine, or simply the O'Brien Mine*. It is a silver-cobalt mine discovered in 1908, acquired by the Miller Lake Co.in 1909 and then Siscoe Mines Limited in 1945. The workings had reached a depth of 1300 feet by 1962 (as reported in "Precambrian" magazine June 1962 issue).
Total production up to 1965 was 36,830,000 oz. Ag and 786,000lbs Co.
*Note; There is also an O'Brien Mine in Coleman Township, near Cobalt.
