Hatch Meadowbank Gold Project

Meadowbank Gold Project

Agnico-Eagle Mines Ltd. | Canada | 2007–2010

8,500 tpd

capacity gold concentrator

28 MW

diesel-power generation plant with heat recovery

US$272 million

CAPEX (Hatch's scope)

−50ºC

Arctic winter conditions

Challenges

  • Design facilities for Arctic conditions: ultra-low temperatures, drifting snow in wintertime and wet ground, permafrost conditions in summer
  • Manage the logistics of a remote air-and-barge-access location and a 10-week shipping season in mid-to-late summer
  • Supply all power and heat from an on-site, diesel-power generation plant
  • Operate in a remote, greenfield location with no existing support infrastructure of any kind

Solutions

  • Provided detailed engineering, procurement, and construction support services for the 8,500 tpd gold processing facilities and site infrastructure, including power-generation plant
  • Waste material from prestripping was used as bulk construction material for erecting dikes and for fill materials around the site
  • Eight major buildings were erected during summer so concrete and equipment installation could continue indoors during the harsh Arctic winter conditions
  • The power plant was designed to include a heat-recovery system, providing heat to the entire mine site complex

Highlights

  • More than 50,000 tonnes of material and equipment were mobilized to the site over a purpose-built, 115 km, all-weather road from Baker Lake
  • Equipment and construction materials were procured in time to be all shipped on barges during a short 10-week ice-free period in summertime
  • Our procurement and logistics strategy helped meet the construction schedule and improved working conditions for contractors through the winter
  • The diesel-fired power plant, heat-recovery, and heat-distribution systems that we designed were rigorous enough for Arctic conditions and resulted in cost savings and schedule improvements
