Newmont's Red Chris Underground Expansion Receives Critical Regulatory Green Light

A Landmark Approval for British Columbia’s Mining Sector

VANCOUVER, BC – June 19, 2026 – The global mining industry is taking note as Newmont (NYSE: NEM, TSE: NGT), the world’s largest gold producer, announced a pivotal development for its Red Chris copper-gold mine in British Columbia. On Friday, the company confirmed that the Red Chris underground expansion project has received all necessary regulatory approvals, marking a significant step towards transitioning the operation from conventional open-pit mining to a more sustainable and long-term underground block caving method. This critical green light is set to extend the mine’s productive life well into the mid-2040s, affirming its strategic importance within Newmont’s asset portfolio and British Columbia’s burgeoning mineral industry.

Newmont operates the Red Chris mine as a joint venture, holding a majority ownership stake, alongside its partner, Imperial Metals (TSX: III), which maintains a 30% interest. The regulatory approvals encompass an amended Environmental Assessment Certificate (EAC), secured through a progressive consent-based process in collaboration with the Tahltan Nation, as well as an amended Mines Act permit from the provincial government. These milestones are crucial "stage-gating" requirements that position Newmont to advance towards a final investment decision (FID) for the project later this year.

Strategic Transition to Block Caving and Substantial Endowment

The core of the Red Chris expansion lies in its transition to block caving, a mass mining method particularly well-suited for large, deep-seated ore bodies characterized by consistent geology. This method, known for its economies of scale and reduced surface footprint compared to traditional open-pit expansions, is key to unlocking the immense potential of the Red Chris copper-gold porphyry deposit. Located within British Columbia’s highly prospective Golden Triangle, the deposit boasts an impressive mineral endowment. Current estimates across its measured, indicated, and inferred resources indicate approximately 20 million ounces of gold and 13 billion pounds of copper.

This substantial resource base underscores the long-term viability of the Red Chris operation. Newmont's management has affirmed that the mine offers "decades of further upside potential beyond this initially permitted phase," signaling a vision for a multi-generational asset within a world-class mining district. The shift to block caving is not merely an operational change; it represents a strategic pivot designed to maximize asset value and extend production horizons responsibly.

Key Players and Collaborative Frameworks

The success of the Red Chris expansion project is a testament to the collaborative efforts of several key stakeholders. At the forefront is Newmont, leading the project development and leveraging its extensive experience in large-scale mining operations. Imperial Metals, as the long-standing joint venture partner, also plays a crucial role.

However, perhaps the most significant element of this approval process has been the active and consent-based partnership with the Tahltan Nation. This approach exemplifies a modern paradigm for resource development in Canada, prioritizing Indigenous rights, environmental stewardship, and shared economic benefits. Newmont CEO Natascha Viljoen highlighted this critical aspect in a press release, stating, "We are proud to have advanced this project through a consent-based framework with the Tahltan Nation, reflecting our shared commitment to responsible resource development." She further emphasized the region's attractive attributes, noting, "With significant mineral endowment, availability of clean hydroelectric power, port access, supportive governments, and strong Indigenous economic leadership, northwest British Columbia is emerging as a world-class mining district."

Newmont’s Expanding Canadian Footprint and Copper Exposure

The Red Chris expansion is also indicative of Newmont’s broader strategic objectives, particularly its increased presence in the Canadian province and its enhanced exposure to critical metals like copper. This strategic shift was significantly amplified by Newmont’s acquisition of Newcrest Mining in a monumental $17 billion deal in 2023. That transaction not only integrated the Red Chris mine fully into Newmont’s operated portfolio but also brought the high-grade Brucejack mine into its substantial asset base.

Newmont has clearly articulated its plans for a lengthy and robust operational presence in British Columbia’s northwest, an area renowned for its abundant gold and copper deposits. The company’s continued investment underscores its confidence in the geological prospectivity of the region and the stability of the regulatory environment, especially when coupled with strong Indigenous partnerships. The demand for copper, driven by global electrification, renewable energy infrastructure, and electric vehicles, makes assets like Red Chris increasingly valuable in a diversified mining portfolio.

Provincial Endorsement and Economic Impact

The regulatory approval of the Red Chris expansion has been met with strong endorsement from the British Columbia provincial government, which views the project as a cornerstone for economic growth and responsible resource development. Premier David Eby issued a statement Friday, remarking, "The Red Chris expansion highlights how partnership agreements with First Nations and a predictable process are creating the certainty needed to move major projects in British Columbia forward." He added that this confidence is "driving historic private-sector investment in B.C. that is creating good job opportunities and family-supporting jobs, and the funding needed to deliver strong public services for people across the province."

The economic benefits for the Tahltan Nation and the wider British Columbia community are expected to be substantial. Michael Goehring, CEO of the Mining Association of British Columbia (MABC), echoed this sentiment in an emailed statement, calling the approval "excellent news for British Columbians and a vote of confidence in BC’s mining sector."

Goehring provided specific figures illustrating the project's forecasted economic contributions:

  • Capital Investment: Several billion dollars in capital funding will be injected into the provincial economy.

  • Job Creation During Construction: More than 1,800 jobs are anticipated during the construction phase of the underground expansion.

  • Sustained Operating Jobs: Approximately 1,500 operating jobs are projected to be sustained during peak seasons until at least 2040.

  • Increased Copper Production: The project is expected to increase Canada’s overall copper production by approximately 15%, significantly contributing to the nation's supply of a critical mineral.

Goehring further highlighted the broader trend, noting, "The Red Chris Block Cave project is the seventh major BC mine or mine extension permitted in the last 18 months." While celebrating this achievement, he urged the provincial government to "build on this momentum by accelerating permitting for more mines to make BC’s and Canada’s economy stronger."

Market Significance and Future Outlook

The successful approval of the Red Chris expansion holds considerable market significance for the mining industry. In a global landscape grappling with increasing demand for base and precious metals, ensuring a stable supply from politically secure jurisdictions is paramount. Copper, in particular, is forecast to experience significant demand growth as the world transitions to a greener economy, while gold continues to serve as an essential store of value and investment hedge.

Newmont is currently completing a definitive feasibility study and detailed cost estimate for the Red Chris Block Cave project. The upcoming final investment decision will be a critical juncture, formalizing the company’s multi-billion-dollar commitment to the project. The long-term vision for Red Chris extends far beyond this initial phase, with the potential for additional expansion and resource utilization, securing its position as a cornerstone asset for Newmont.

As British Columbia continues to establish itself as a preferred jurisdiction for mining investment, the Red Chris project serves as a powerful example of how strategic partnerships with Indigenous communities, coupled with predictable regulatory processes, can unlock significant mineral wealth and deliver lasting socio-economic benefits. The industry will be closely watching Newmont's progress as it moves towards FID and begins to execute this ambitious underground expansion, further solidifying its leadership in global gold and copper production.
