Discovered in 1908 by Robert Mann. Two shafts were sunk between 1912 and 1914 the deepest being 200 feet with three levels. It produced a total of 99,000 ounces of silver during that period. In 1952 Siscoe Metals milled the mine waste rock and recovered 20,000 ounces of silver from it.
In 1961 Manridge Mines Limited acquired the property and between 1968 and 1970 produced 174,000 ounces of silver. In 1984, Manridge Explorations drove a 750 foot ramp to a vertical depth of 135 feet to explore a new zone (D-zone) and recovered about 8,000 ounces. Reserves in the D-zone were estimated to be 87,000 ounces.
The silver occurs in calcite veins that strike WSW in Nipissing Quartz Diabase. They were a producer of fine dentritic silver crystal specimens.
