The mine is located in the Casa Berardi Township, north-eastern Quebec, straddling the Ontario border. Casa Berardi is an underground operation that comprises the former West and East mines, separated by the Principal deposit. Open pit ore production commenced in 2016 from the East Mine Crown Pillar (EMCP) pit, and is expected to increase gold production by 30koz/a over a 5 - 6 year mine life. The plant comprises a carbon-in-leach (CIL) circuit which was modified in 2016 to allow increased throughput from open pit operations. Throughput is expected to increase to 3.6kt/d following commencement of ore production from the EMCP pit. Casa Berardi produced 146koz of gold in 2016, and is expected to produce between 150 - 165koz of gold in 2017.
