Eleonore gold mine

Eleonore Underground Gold Mine is located in Eeyou Istchee/James Bay, in a remote corner of the Northern Quebec region, 800 kilometres north of Montreal on the 52nd parallel.

Eleonore is a world-class, state-of-the-art facility that is among the largest gold mines in Quebec.

Its first gold pour was on October 1, 2014, and it achieved commercial production on April 1, 2015.

Gold comes from the Roberto Deposit, which is marked by complex folding and faulting and is still open down plunge. The ore is mined from four horizons using sill and stope techniques, then processed onsite using a conventional circuit that includes crushing, grinding, gravity, flotation and cyanidation. Overall gold recoveries are 92%.

The operation has begun to develop a fifth mining horizon and build a production shaft, both of which will bring Eleonore closer to its full production capacity.
