The Hoyle Pond underground mine is accessed by decline and by a shaft. The current winze configuration has the potential for expansion to access below 2,000 metres. Mining methods employed are conventional cut and fill, shrinkage, panel mining and longhole methods in wider zones.
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 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 the Best Management Plan, signed with the City of Timmins, and the Ministry of Environment’s noise, air and vibration guideline limits. Site stripping and mining activities currently take place during the day until the Environmental Control Berm is constructed around the pit periphery. The berm is designed to reduce noise levels and once complete, fulltime 24 hour operations will commence.
