Gold Project, Eleonore Mine - ASDR Canada

Gold Project, Eleonore Mine


Mandate and Objectives

Eleonore is an underground gold mine located in the James Bay region (Eeyou Istchee) in northern Quebec. It can extract up to 7,000 tons per day of ore which it processes on site via a crushing, grinding, gravity separation, flotation and cyanidation circuit.

Goldcorp (Newmont) mandated ASDR for the design of surface and underground infrastructures as well as the management of the project as an integrated team. The infrastructures allowed to mine the gold deposit at full capacity. The design had to be optimal and flexible, in accordance with the production capacity from the exploration and production well.

Challenges and Issues

  • Management of a 900$ M project
