Trekor Advances Environmental Assessment for Yellowhead Copper Project

Economic Impact Study highlights benefits of proposed copper mine

VANCOUVER, British Columbia, July 07, 2026 (GLOBE NEWSWIRE) -- Trekor Metals Limited (TSX: TKO; NYSE American: TGB; LSE: TKO) (“Trekor” or the "Company") is pleased to provide an update on the Environmental Assessment (EA) process for its 100%-owned Yellowhead Project (“Yellowhead” or the “Project”), a proposed open-pit copper mine located in British Columbia's Thompson-Nicola region.

A Detailed Project Description (“DPD”) for the Yellowhead Project was recently submitted to the BC Environmental Assessment Office. The DPD provides more information about the proposed Project, incorporating additional technical work and community feedback received during the Early Engagement Phase of the EA process. More than 1,000 local community members have participated in a series of open houses and events hosted by the project team.  

The DPD submission marks an important milestone, advancing the Project to the next phase of the provincial EA process and informing the Readiness Decision and Process Planning phases to come.  Process planning and scoping work is also underway for the Simpcw Process – an Indigenous-led, consent-based decision-making model.

Stuart McDonald, President & CEO of Trekor, commented, “We have been pleased with the level of community engagement to date, which has helped inform refinements to the project in certain areas, while maintaining the overall project design and objectives.  Environmental studies and engineering work continue to advance with a site investigation and drilling program planned for this summer.”

In conjunction with the DPD submission, Trekor has released a comprehensive economic impact study, prepared by MNP, which evaluates the potential economic impact of the construction and operation phases of the Yellowhead Project.  To view the full report, visit: Yellowhead Economic Impact Study

Study highlights include*:

• Major Economic Driver: The Yellowhead Project will generate total economic output in Canada of approximately $47 billion and value-added GDP of $27.3 billion. Approximately 70% of this economic activity will occur in BC’s Thompson-Nicola region, contributing $33 billion in economic output and $20 billion in value-added GDP to the region.
• Catalyst for Local/Regional Employment: During mine operations, Yellowhead will directly employ approximately 525 workers. The Project will also support 3,305 total jobs, including direct, indirect and induced employment.
• Stable, Well-Paid Jobs: Yellowhead will provide secure, long-term, well-compensated employment opportunities, with total compensation for direct workers averaging $153,000 per year (more than double the average income in the region). The mine’s direct payroll in the Thompson-Nicola region will total $81 million per year during operations and more than $2 billion over a 25-year operating life.
• Significant Construction-Phase Benefits: During its 2–3 year construction phase, Yellowhead will generate an estimated $835 million in labour income, mostly within B.C., while providing a substantial economic boost for local communities and businesses.
• Significant Contributions to Government: The Yellowhead Project will be a major contributor to government revenues at the local, provincial, and national levels, supporting essential programs and services. Over the construction and operations phases, Yellowhead will generate approximately $7 billion in payments to governments in Canada.
• Leading Producer of Critical Minerals: Yellowhead will be a major new source of copper in Canada, with average annual life-of-mine production of 178 million pounds of copper in concentrate over the 25 year mine life. This level of production will make it the country’s second-largest copper producer, increasing Canada’s annual copper output by 16% over 2025 levels.
• Copper is a critical material in a wide range of construction, industrial and technology applications, and is subject to rapidly expanding market demand associated with renewable energy systems, electrification and electric vehicles, defense spending, and AI data center development. Copper is designated a Critical Mineral by the governments of British Columbia and Canada.
  
  

“The Yellowhead Project represents a significant opportunity for job creation and economic growth, locally and nationally. It will be a catalyst for regional employment, creating well-paid jobs for a generation of BC workers. The mine, which is designed to produce 178 million pounds of copper annually over a 25-year mine life, would strengthen BC’s provincial economy and improve national trade diversification,” commented Stuart McDonald, Trekor President & CEO.

Trekor’s North American copper business is growing significantly in the near-term, with the addition of new copper production this year from Florence Copper in Arizona to existing production from the Company’s flagship asset – the Gibraltar copper mine in BC’s Cariboo region. Future production from Yellowhead would establish Trekor as one of the largest copper producers in North America.

About the Yellowhead Project

The Yellowhead Project is a proposed open-pit copper mine located in the Thompson-Nicola region of British Columbia, approximately 150 kilometres northeast of Kamloops, along Highway 5, near the community of Vavenby. The Project is situated within the territory of Simpcw First Nation (Simpcwúl̓ecw).  

Yellowhead has entered into the provincial Environment Assessment process administered by the BC Environmental Assessment Office and the Simpcw Process, an Indigenous-led assessment model.

These included but are not limited to:

• uncertainties about the future market price of copper and the other metals that we produce or may seek to produce;
• changes in general economic conditions, the financial markets and in the market price for our input costs including due to inflationary impacts, such as diesel fuel, acid, steel, concrete, electricity and other forms of energy, mining equipment, and fluctuations in exchange rates, particularly with respect to the value of the U.S. dollar and Canadian dollar, and the continued availability of capital and financing;
• inherent risks associated with mining operations, including our current mining operations at Gibraltar and Florence Copper, and their potential impact on our ability to achieve our production estimates;
