COMPANY PROFILE

Dominion Diamond Mines ULC

Dominion Diamond Mines ULC (Dominion) is a Canadian diamond mining company with ownership interests in two major producing diamond mines situated approximately 200 kilometers south of the Arctic Circle in Canada’s Northwest Territories. The company owns and operates the Ekati Diamond Mine and owns 40% of the Diavik Diamond Mine. It supplies rough diamonds to the global market through its sorting and selling operations in Canada, Belgium and India.

The Ekati mine site is located roughly 300 kilometres northeast of Yellowknife and can only be accessed by air and by a 400-kilometre ice road for approximately two months in the winter. Diavik Diamond Mines Inc., a subsidiary of Rio Tinto plc, operates the Diavik Diamond Mine. TSM results for Diavik are provided by Rio Tinto.

At Dominion, performance means delivering sustainable growth by investing in the future. That involves supporting excellence in leadership and delivering on the commitment of zero harm: to the company’s own people, through consistent and risk-based work practices; to its host communities, through communication and the inclusion of their opinions and concerns in mine plans and mine-life extension projects; and to the environment, through innovative adaptive management and intensive monitoring of the mine’s impact.

Dominion is proud of the Ekati mine’s performance and is dedicated to building on its legacy. The company will continue to work closely with its impact benefit agreement (IBA) groups, maintaining a focus on the empowerment and sustainability of the northern communities. With such a solid foundation, Dominion will concentrate on making improvements and enhancements.

Dominion uses TSM reporting as part of a suite of tools that drive continuous improvement across the company’s operations. The company conducts extensive internal and external monitoring and auditing of all sustainable development practices, and the TSM initiative draws many of these processes into a forum for wider reporting across Canada. This extra level of self-regulation adds value because processes are reviewed from a different reporting perspective than would be the case under other HSEC (health, safety, environment and community) and ISO audits.

Biodiversity Conservation Management, Indigenous and Community Outreach, and Crisis Management and Communications Planning are areas where the Ekati mine has consistently scored high, and that trend continued in 2019. The company meets regularly with stakeholders to share information about its operations and future plans and to hear feedback on decisions that may affect them. The Ekati mine has created community development plans that focus the company on where its efforts will make the most difference. While the company inherited the IBAs, which are in place until the end of mine life, Dominion is in ongoing dialogue with its IBA partners to explore additional community development initiatives.

Dominion continues to make considerable effort in the stewardship of the environment. The results achieved in 2019 verify that those efforts are on track in terms of understanding and conserving biodiversity, effectively disposing of processed kimberlite, executing energy reduction projects, and managing water quality.

Dominion’s results illustrate that the company is committed to fulfilling its vision of strengthening and deepening its relationships with community stakeholders and extending mine life. The company is striving to make developments to the Ekati mine’s socioeconomic and environmental records where sustainable resource development and community growth are paramount. By incorporating Traditional Knowledge and feedback from community partners, Dominion will become better at what it does. The company genuinely cares about its people and wants to make investments that have long-lasting benefits.
