from Yellowknife to site

2,500

truckloads

3 million tpa

plant capacity

4th diamond mine

in Northwest Territories

Challenges

  • In this Arctic climate, all heavy equipment, most bulk supplies, and fuels must be trucked in along ice roads open only during February and March.
  • The completion of the project depended on the success of the ice road campaign in the winter of 2015, when the majority of construction material were shipped to site.
  • Meticulous logistics and careful contingency plans supported more than 2,000 truckloads that traveled the 420 kilometers to the site.

Solutions

  • We are providing full EPCM service
  • Our scope includes design and development of the processing plant and all support facilities. People were accommodated on site as construction peaked during the summer of 2015.
  • About 250 full-time employees make up each rotation during construction at this fly-in/fly-out remote work site.
  • The process plant is designed to handle 3 million tonnes per annum(tpa). The mining operation must move approximately 30 million tpa of rock to access the kimberlite ore body.

Highlights

  • This fourth diamond mine in the Northwest Territories is the fifth one to be developed north of the 60th parallel since the early 1990s.
  • Recognized by the Project Management Institute with the Project of the Year Award in 2016
  • Our experts contributed to environmental-requirements monitoring and reporting for permit compliance. We oversaw the feasibility study, completed at an estimated C$1,019 million.
  • The first diamond was achieved on June 30, 2016 and the project has moved into the production phase. The final cost is estimated to be, C$1.056 billion.
  • This is one of the few De Beers-Anglo projects forecasted to be completed on schedule and within its targeted budget.

“Hatch has performed well on a very challenging project with exceptionally tight timelines. The project has, to date, been executed in timely and safe manner. The EPCM and owners team have established and maintained an excellent working relationship. ”
