Lac des Iles




Lac des Iles

Lac des Iles (LDI), North America’s only producing  graphite mine, sets us apart and propels us towards an era of production growth and sustainable development. LDI hosts battery-grade graphite and is a cash-generating asset with an established customer base.

LDI has 213,000 tonnes of M&I Resources with potential to grow(1)​ and it can be scaled to meet market demand in a low-cost, timely manner by leveraging its fully permitted mine, plant and tailings facilities​. A new mineral reserve estimate is expected to be published​ in early 2024​​​​. The potential exists to significantly expand production at LDI through drilling of exploration targets and processing material from ​Northern’s wholly-owned Mousseau deposit​.

Producing Asset

  • Currently producing 10-15,000 tpy​
    of graphite concentrate​​
  • Ramping up to nameplate capacity of 25,000 tpy​
  • 7 years tailings capacity​​
  • Located 150 km northwest of Montreal, Quebec​​

Proven Value

  • Battery-grade graphite​​
  • Established customer base​​
  • Cash generating asset
  • Updated mineral resource shows potential to extend mine life by 8 years
  • 213,000 tonnes of M&I Resources with potential to grow

Path Forward

  • New mineral reserve estimate expected to be published​ in early 2024​​​
  • Lac des Iles (LDI) can be scaled to meet market demand in a low-cost, timely manner by leveraging the fully permitted mine, plant and tailings facilities
  • LDI can be extended through drilling of exploration targets and processing material from wholly-owned Mousseau deposit
