Gold is recovered using a combination of gravity concentration and cyanidation techniques. The circuit consists of primary, secondary and tertiary crushing, rod/ball mill grinding, gravity concentration, cyanide leaching, carbon-in-pulp gold recovery, stripping, electro winning and refining.
The Hollinger open pit is located in the City of Timmins located adjacent to residents and businesses. The pit will reclaim 250 acres of currently unusable and unsafe land for future safe public use. All permits have been received following a period of public consultation and the installation of a monitoring system ensuring the pit can meet i’s Best Management Plan and Ministry of Environment noise, air and vibration guideline limits. Site stripping and mining activities will take place on day shift only in 2013 until an Environmental Control Berm is constructed around the pit periphery to reduce noise levels, at which time full time 24-hour operations will commence.
