Rio Tinto plc: Sustainable Demolition Partnership for Diavik Diamond Mine Closure Announced

Strategic Partnership for Sustainable Demolition at Diavik Diamond Mine

In a significant move towards sustainable practices in mining, Priestly Demolition Inc. (PDI) announces a partnership with the Indigenous joint venture DJRM First Nations Construction Corporation, which includes Denesoline Corporation. This collaboration is aimed at providing demolition services for the closure phase of the Diavik Diamond Mine, set to cease operations in early 2026. Located in the Northwest Territories, Diavik has been a key player in the diamond mining industry since its inception in 2003, becoming the first Canadian diamond mine to exceed 150 million carats in production as of 2025. As the mine transitions towards closure, PDI is focused on executing demolition activities in a manner that minimizes environmental impact while fostering a positive legacy for the local community.

PDI is currently in the planning stages and aims to begin demolition activities in 2026. The company emphasizes the importance of responsible closure that respects the environment and the future of the Indigenous communities surrounding the mine. Shane Stewart, President & CEO of PDI, underlines the commitment to leave behind opportunities for future generations, ensuring that the community benefits from the closure process. The demolition will encompass dismantling existing infrastructure, and PDI plans to work closely with Indigenous communities and regulatory bodies throughout this process. This collaboration is crucial, especially given the challenges posed by the mine's Northern location, where environmental integrity is a paramount concern.

While mining operations will conclude in 2026, the active closure activities, which have been ongoing since 2017, are anticipated to wrap up by 2029. PDI’s involvement underscores a commitment to adhering to Diavik’s Final Closure and Reclamation Plan, which prioritizes the careful management of the site for the benefit of Northern communities. The partnership with Denesoline Corporation, a vital component of the DJRM joint venture, highlights the importance of Indigenous-led initiatives in promoting sustainable practices in the mining sector. PDI’s expertise in complex remote projects positions them well to execute this demolition safely and in alignment with community goals.

In related developments, the Diavik Diamond Mine has had a significant impact on the local economy and Indigenous communities since its establishment. The mine has not only provided employment opportunities but has also fostered partnerships that empower Indigenous voices in resource management. As the mine approaches its closure, these relationships will be crucial in shaping a sustainable future for the region. PDI’s approach to the demolition process reflects a growing trend in the mining industry to prioritize environmental stewardship and community engagement, setting a precedent for future mining closure projects.
