Rio Tinto Ends Production at Diavik Diamond Mine: What It Means for Canada’s North

Yellowknife, Canada — Rio Tinto has officially completed its final ore haul from the Diavik Diamond Mine on March 24, marking a historic milestone in Canada’s diamond mining industry.

After more than two decades of continuous operation, the closure of Diavik signals the beginning of a transition phase for one of the most productive diamond mines in North America.

Key Highlights

  • Final ore extraction completed on March 24
  • Over 150 million carats of rough diamonds produced
  • Mine operated for 23 years
  • Closure and land reclamation planned through 2029

A Landmark in Canada’s Diamond Industry

Located in the remote Northwest Territories, just south of the Arctic Circle, the Diavik mine has been a cornerstone of economic development in northern Canada.

Since its launch in 2003, the mine has produced more than 150 million carats of rough diamonds, contributing significantly to regional employment, infrastructure, and Indigenous partnerships.

Matthew Breen, Chief Operating Officer of Diavik, described the milestone as:

“A historic day for Diavik and the Northwest Territories and a great source of pride for this unique Canadian success story.”

Indigenous Partnerships and Economic Impact

A defining feature of the Diavik project has been its collaboration with Indigenous communities. Partnerships with local Indigenous governments helped create long-term socioeconomic benefits, including:

  • Employment and training opportunities
  • Local business development
  • Community investment initiatives

This collaborative model is often cited as a benchmark for responsible mining practices in Canada.

What Happens Next? Closure and Reclamation Plans

Although production has ended, Rio Tinto confirmed that closure activities will continue until 2029, followed by long-term environmental monitoring.

The company has committed to restoring the land in partnership with:

  • Local Indigenous groups
  • The Government of the Northwest Territories

Breen emphasized:

“We look forward to continuing to respectfully reclaim the land in line with our commitments.”

Diamond Supply Chain: What About the Final Production?

The last batch of diamonds from Diavik will not disappear immediately from the market.

Instead:

  • Rough diamonds will be polished and distributed through Rio Tinto’s global network
  • Sales are expected to continue through 2026 and beyond
  • Distribution will include the company’s Select Diamantaires

This ensures that Diavik diamonds will remain part of the global supply chain even after mining operations cease.

Industry Perspective: End of an Era

The closure of the Diavik mine represents a broader shift in the global diamond industry, where aging mines are reaching the end of their lifecycle.

However, it also highlights:

  • The importance of sustainable closure planning
  • The role of ethical mining partnerships
  • The long-term impact of resource extraction on local communities

Conclusion

The end of production at the Diavik Diamond Mine marks the conclusion of a highly successful chapter in Canada’s mining history.

While operations are winding down, the mine’s legacy—economic development, Indigenous collaboration, and responsible mining practices—will continue to shape the future of the industry.
