Diavik

Closing responsibly, closing with care

All mines have a finite life cycle, and Diavik planned for closure from the outset. Closure activities were integrated into mine planning and operations from the very beginning, making us a leader in Canadian mine closure.

With mining now complete, Diavik is progressing through decommissioning and reclamation. Buildings and infrastructure are being decommissioned, salvaged where practical, or demolished safely. Lake water is being returned to the mine pits and will be tested for quality before it is ultimately reconnected with Lac de Gras.

Innovation at Diavik

The design, construction and operation of Diavik is a story of success on a grand scale, in part because it is in one of the most challenging environments in the world: the sub-Arctic tundra, a pristine landscape with a delicate ecosystem. We remain committed to protecting the biodiversity of this unique landscape. 

Through innovation, world class engineering technologies and in collaboration with local Indigenous partners, we were able to mine some of the world’s most ethical diamonds. These foundations continue to guide a responsible and carefully planned closure, with a focus on leaving the site safe and stable for the long term.

Reducing emissions

Our focus on minimising our environmental impact and reducing the use of diesel was inherent in our construction of the first large-scale wind farm in Canada’s territories in 2012. During Diavik’s operations, it generated over 200 million kilowatt‑hours of renewable electricity, reduced greenhouse gas emissions and displaced millions of litres of diesel fuel.

Diavik also constructed a 6,600-panel solar facility in 2024. At the time of its construction, it was the largest off‑grid solar power project in Canada’s North. This facility generates approximately 4.2 million kilowatt‑hours of carbon‑free electricity each year and will continue to play an important role in reducing emissions during closure activities.
