Teck Resources Limited (TSX: TECK.A,OTC:TCKRF and TECK.B, NYSE: TECK) ("Teck") today announced board approval for construction of the Highland Valley Copper Mine Life Extension Project (HVC MLE), an important critical minerals investment which will extend the life of Canada's largest copper mine and support Teck's copper production into the future.
"This extension of Canada's largest copper mine, Highland Valley Copper, is foundational to our strategy to double copper production by the end of the decade," said Jonathan Price, President and CEO. "Given the strong demand for copper as an energy transition metal, the Highland Valley Copper Mine Life Extension will generate a robust IRR and secure access to this critical mineral for the next two decades. The project will strengthen Canada's critical minerals sector, generate new economic activity, and support the continuation of the jobs and community benefits that HVC generates for many more years to come."
"We look forward to continuing to work collaboratively with Indigenous Governments, local communities and stakeholders to responsibly secure the long-term future of Highland Valley Copper," added Price.
The decision to sanction HVC MLE was assessed under Teck's Capital Allocation Framework using a rigorous decision-making approach that included a robust business case focused on returns and increased assurance requirements, which demonstrated sanction-readiness.
Project highlights:
- Mine life extension of Highland Valley Copper from 2028 through to 2046.
- Average copper production of 132,000 tonnes per year over the life of mine.
- Positioned for solid execution with strong and experienced team in place, all major permitting complete, engineering nearly 70% complete, and contracting and procurement well advanced.
- Total capital investment represents the largest critical minerals investment in British Columbia history.
- Maintains the approximately 1,500 direct jobs and $500 million in annual GDP from HVC's operations.
- Expected to generate approximately 2,900 jobs and $435 million in additional GDP during the construction phase of the project.

About HVC MLE
HVC MLE is a brownfield extension of our operational asset, Highland Valley Copper (100% Teck owned) in British Columbia, from 2028 out to 2046.
The environmental assessment certificate and required permits for HVC MLE were issued in June 2025, and construction is set to commence in full in August 2025. The project consists of upgrades and increased capacity requirements for the mine life extension and a mine pushback that requires additional waste-stripping to access high-quality ore within the Valley Pit.
Additional technical and engineering work has been completed ahead of sanctioning to optimize the project. Accordingly, the project capital estimate has been refined and is now expected to be between $2.1 to $2.4 billion, reflecting the class of capital cost estimate, updated assumptions based on prevailing construction industry risks, and the potential impact of tariffs, with further potential opportunities for cost optimization during construction. This capital is expected to be invested from H2 2025 through 2028. This project capital investment includes the development of site infrastructure and facilities, expansion of the mine fleet, grinding circuit upgrades, increased tailings storage capacity, and enhancements to power and water systems. The refined growth capital estimate is based on a high-definition cost baseline informed by early contractor involvement. It includes project-level contingencies, accounts for inflation and input cost escalation, the impact of potential tariffs on construction materials, and reflects the accelerated procurement of mobile equipment originally planned for later project phases. The estimate also incorporates additional scope and indirect contractor requirements identified through ongoing project refinement.
The production profile at Highland Valley Copper is divided into three distinct mining phases with different material movement expected in each phase:
- Mining the current Valley and Lornex pits (2025-2027)
- Transitioning through satellite orebodies (Bethlehem and Highmont) and lower grade Valley ore while completing the next Valley pit pushback (2028-2033)
- Valley pit becomes the dominant ore source and is a long-term source of high-quality ore (2034-2046)
Total Material Movement and Ore Tonnes Mined
Although the annual ore throughput rate will be variable due to ore hardness, the long-term ore tonnes mined will remain consistent at approximately 50 million tonnes per annum through the life of mine. However, total material moved will increase starting with Phase 1 of the project, which requires additional waste stripping to access the high-quality ore in the Valley Pit. During Phase 2, the average total tonnes mined will continue to increase to approximately 200 million tonnes on average from 2028-2033. Thereafter, in Phase 3, total tonnes mined will reduce to approximately 100 million tonnes on average, with a gradual reduction in tonnes mined from 200 million tonnes to 100 million tonnes through to 2038, and minimal waste tonnes mined from 2039 to the end of the life of mine in 2046.
Grade and Production
The grade profile of production is variable depending on the ore input material. Higher grade material is expected during Phase 1 as an increasing proportion of ore from the Lornex pit is mined. In Phase 2, as mining progresses to the satellite orebodies at Bethlehem and Highmont, grade will decrease while the pushback and increased waste stripping of the Valley pit takes place. Thereafter, in Phase 3, the high-quality Valley pit ore is mined with improved grades. Production volumes will vary in accordance with the grade profile as mill throughput remains consistent throughout the mine life.
Guidance
Our previously disclosed 2025 annual growth capital expenditure and capitalized stripping, and annual 2028 production guidance for HVC has been updated to reflect the sanctioning of HVC MLE. Capital expenditure guidance for 2026 and production guidance for 2029, including HVC MLE, will be disclosed when we issue our annual guidance in January 2026, consistent with our usual process. Guidance reflecting these updates is disclosed in our Q2 2025 News Release and Management's Discussion and Analysis issued on July 23, 2025.
Quotes:
David Eby, Premier of British Columbia –
"We promised British Columbians we would move big projects forward faster to counter the threats we face. This multi-billion dollar project represents 2,900 new jobs and a $500 million increase to GDP. It's just one example of how British Columbia can drive our country's economy forward even in challenging times. Congratulations to everyone involved - let's keep going!"
Christine Walkem, Chair of CNA's Board of Directors, Chief of Cook's Ferry Indian Band –
"The Citxw Nlaka'pamux Assembly (CNA) recognizes the Teck Board's approval of the Highland Valley Copper Mine Life Extension project as a defining moment — not just for industry, but for the 8 Participating Bands of the CNA. This project is moving forward because of the unwavering leadership and community members participation. Through our nłeʔképmx Impact Assessment and as authors of our own sections into the Environmental Assessment application, the CNA established a new precedent in Canada — one where Indigenous law, Indigenous governance, and Indigenous authority are not just consulted, but embedded at the heart of decision-making about our lands, waters, and people. Our communities are not bystanders to development — we are decision-makers. We are forging a new path with Industry and the Crown for how major projects unfold in our territory: grounded in respect, guided by our values, and focused on long-term benefit for our people. As the project enters construction, we remain firm in our expectations. Our voices must continue to be heard. Our laws must continue to guide the process. Our people must continue to share in the benefits — now, and for generations to come."
