  • High arctic environment and Inuit culture
  • Cold regions engineering
  • Geotechnical and geomechanical engineering services in permafrost
  • Alternative energy feasibility studies
Project Overview

The Mary River Project is located on Baffin Island in the Qikiqtani Region of Nunavut, Canada. The project is approved as a 22.2 million tonne per year (Mtpa) open pit iron ore mining operation, with a railway over continuous permafrost and year-round shipping using ice breaking bulk carriers. An initial 4.2 Mtpa operation was commissioned in 2015. The project owner, Baffinland Iron Mines Corporation, is currently seeking approval for a stepwise expansion to 30 Mtpa.

Project Role

Knight Piésold has been providing environmental services for the project since 2004, including:
