Gold was discovered here in 1916 and the property was brought into production by Hollinger Corp. in 1934. Between 1934 and 1957 the mine produced 6,218,272 tons grading 0.094 oz/t. mainly from quartz stringer zones(and associated pyrite) in altered syenite. Various companies have been drilling on the property ever since and Northgate Minerals Corp. is currently bringing this mine back into production together with the adjacent Matachewan Consolidated Mine. Production is expected to commence in 2012 at a rate of 6,000tpd.
