Of the numerous major gold mining operations around the world, most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit. The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates.

The mine is situated in the area of the historic Detour Lake open pit/underground mine operated by Placer Dome which produced million ounces of gold from 1983 to 1999. The Detour Lake operation has a mine life of approximately 22 years with an average gold production of 659,000 ounces per year.

The mine operated until 1941, when wartime economic pressure caused the mine to shut down. In 1981 Westmin Resources owned the property, and after undertaking a drill program started operations on the old Silback Premier property in 1989. A mill was built and open pit mining and an underground mining operation began in March of 1989.
