Vale Base Metals’ Thompson operation is home to the world’s fourth northernmost nickel mines and an important part of Canada’s mining legacy.

About the Operation

Our Thompson operation in Northern Manitoba is comprised of one operating mine and a nickel concentrator processing plant. It has been in production since 1961 and is located in the heart of the northern boreal region adjacent to the City of Thompson.

About the Deposit

Following the discovery of a major ore body in 1956, Thompson went on to become the fourth-largest Class 1 nickel sulphide resource globally.

Thompson produces about 10 to 15 per cent of annual Canadian nickel production. Nickel concentrate is transported by rail to Vale Base Metals’ nickel refineries in Ontario and Newfoundland before being shipped to domestic and international markets.

Commitment to Communities

Significant Social Investments

Each year, the Thompson operation invests an average of $750,000 in local events, sponsorships, and charitable initiatives that reflect Vale Base Metals’ core values and strengthen the fabric of the community. The operation’s support goes beyond financial contributions — it’s a partnership with the people and organizations that help the City of Thompson thrive.

A cornerstone of this commitment is our $2 million investment over four years in the City of Thompson’s new aquatic centre and recreational facility, opening in 2026. The Thompson operation also supports cultural recognition and reconciliation through annual funding for National Indigenous Peoples Day and the National Day for Truth and Reconciliation.

The operation’s investments include youth development, education and literacy, health and wellness, food security, and local community events. Thompson champions animal welfare through financial contributions to local shelters and responds to crises with humanitarian aid and disaster relief for communities in need.

Indigenous Partnerships

Thompson is located on Treaty Five, the traditional territory of the Nisichawayasihk Cree Nation and Tatasweyak Cree Nation, and the traditional homeland of the Red River Métis. This land acknowledgement is foundational to how Thompson operates, collaborates, and grows.

The operation’s partnerships with Indigenous communities are transformational, not transactional. Thompson is committed to building respectful, long-term relationships that foster reconciliation, shared prosperity, and cultural understanding. Through ongoing collaboration with Treaty 5 Nations, Thompson continues to deepen its awareness of Indigenous histories, cultures, and priorities.

A key milestone in this journey is Thompson’s 2024 Exploration Agreement with NCN, which reflects a strong, trust-based partnership and opens doors to future opportunities in employment, procurement, and community development. The operation is also working toward an Impact Benefit Agreement (IBA) that will formalize its shared commitment to economic inclusion and regulatory collaboration.

Regreening Efforts and Environmental Stewardship

Thompson is certified under ISO 14001:2015, the internationally recognized standard for environmental management systems. This certification reflects Thompson’s commitment to continuous improvement, regulatory compliance, and employee engagement in environmental performance across its operations.

One of Thompson’s standout initiatives is the regreening of clay-capped slag piles, where traditional grass applications proved unsustainable. Instead, the operation’s environment team piloted test plots using nitrogen-fixing legumes, which naturally enriched the soil and encouraged the growth of local vegetation. This approach supports biodiversity, controls erosion, and fosters pollinator habitats—enhanced by nine on-site beehives maintained by a local apiarist. These bees contribute to revegetation efforts and produce honey.

Thompson’s Water Quality Management Program includes a long-term perimeter study launched in 2021, monitoring groundwater flow and quality across key sites such as the tailings storage facility and former mine areas. With over 60 monitoring wells, the operation ensures water leaves its property only where designed and meets all environmental standards. Regular testing of surface and groundwater, along with monitoring of local flora and fauna, helps Thompson maintain ecological balance and transparency.

Innovation

Thompson has evolved from one of the world’s first fully integrated mining complexes to a streamlined mining and milling operation, reflecting more efficient practices across the Vale Base Metals’ portfolio. This shift allows for optimized resource use while maintaining a strong focus on safety, sustainability, and productivity.

A standout innovation is the implementation of centralized surface blasting, a method that enhances underground safety and is now considered a benchmark in Canadian mining practices. Further advancing operational efficiency, Thompson’s Integrated Remote Operations Centre (iROC) now supports the operation’s T3 mine, using real-time digital connectivity to monitor underground activities from the surface. This system enables rapid issue detection and resolution, improving safety and productivity while providing leadership with valuable operational insights.
