Client : Goldcorp

Service : Mining Engineering


Located in the Eeyou Istchee/James Bay region in northern Québec, this underground gold mine produces 7,000 tonnes of ore per day that is processed on-site in a crushing, grinding, gravity separation, flotation and cyanidation circuit. Goldcorp mandated ASDR to design surface and underground infrastructure to allow it to mine the gold deposit. The design had to be optimum and flexible while meeting production capacity when the exploration and production shafts are fed.

Work Performed

System design and detail engineering (mechanical and structural) for the following infrastructure:

Mechanical and structural:

  • Underground fuel and lubricant distribution and storage network (lines, SatStat, etc.);
  • Loading station (metering box, chute, bins, etc.) on the 690 Level; and
  • Backfill handling system (conveyors, feeder, arched doorway, outlet regulator, raise, screen, crusher, bins, etc.) on the 690 Level.



  • Manage and coordinate the installation of a service winch;
  • Remote locking system for the production shaft’s winches;
  • Bin Structure 04-020 and Transfer Tower CVO-01 05-056 (power, duty, instrumentation and automation); and
  • Procurement engineering.

Performance and results

Two crusher plants, screen, bins to supply two raises and a conveyor with a reversible conveying direction. The mine currently produces 7,000 tonnes of ore per day.
