Red Chris Mine: A Blueprint for Green Copper and Indigenous Partnership

VANCOUVER, BC – June 19, 2026 – In a move that sends ripples across Canada’s resource and environmental sectors, the Red Chris copper and gold mine has received pivotal provincial authorizations to transition from an open pit to a massive underground block cave operation. The approvals, granted by British Columbia, not only extend the mine’s life into the mid-2040s but are built upon a historic consent-based agreement with the Tahltan Nation, on whose territory the mine operates. This landmark decision sets the stage for a final investment verdict later this year by joint-venture partners Newmont Corporation (70%) and Imperial Metals (30%), potentially unlocking one of the most significant mining developments in a generation.

Forging a Partnership on Tahltan Land

At the heart of the Red Chris expansion is a groundbreaking model of collaboration. The project’s approval hinges on a consent-based decision-making agreement signed in November 2023 between the Tahltan Nation and the Province of British Columbia. As only the second such agreement under the province’s Declaration on the Rights of Indigenous Peoples Act (DRIPA), it grants the Tahltan Central Government direct authority to approve or reject any substantial changes to the mine, effectively making them equal partners in the governance of their land. This framework moves beyond mere consultation, embedding Indigenous rights and authority directly into the regulatory process.

The economic implications for the Tahltan Nation are already profound and set to grow. The mine currently employs around 220 Tahltan members in high-paying roles, with the Tahltan Nation Development Corporation (TNDC) generating approximately $100 million in annual business from the operation. The nation also receives royalties and a share of provincial mineral taxes. Leaders within the Tahltan Central Government have characterized the agreement as a “significant milestone on our path toward reconciliation,” demonstrating that robust economic development and stringent environmental stewardship can, and must, coexist. This partnership is being watched closely as a potential blueprint for how resource projects can advance with Indigenous communities not as stakeholders, but as rights-holding partners.

Fueling a Copper-Hungry World

The timing of the Red Chris expansion could not be more critical. The world is facing a structural deficit in copper, a metal indispensable to the green energy transition. From electric vehicles and wind turbines to grid modernization, the global push toward decarbonization is projected to nearly double copper demand by 2035, according to S&P Global. Supply, however, is failing to keep pace, with years of underinvestment and declining ore grades creating a looming shortfall.

Against this backdrop, the Red Chris block cave project emerges as a development of national and global strategic importance. The expansion is projected to increase Canada’s total copper production by an astounding 15 percent, helping to reverse a decade-long decline in the country's output. With an expected workforce of over 1,800 during construction and 1,500 during peak operations, the project promises a massive economic injection into British Columbia. Its significance is further underscored by its inclusion on the Canadian government's list of fast-tracked, nation-building projects, signaling federal support for its role in securing critical mineral supply chains.

The Long Shadow of the Past, A Vision for the Future

The path to this point has not been without its challenges, and the project carries the weight of history. Minority partner Imperial Metals remains inextricably linked to the 2014 Mount Polley disaster, when a tailings dam breach released millions of cubic meters of waste into the Fraser River watershed. That event serves as a stark reminder of the risks inherent in large-scale mining and has permanently raised the bar for environmental oversight and corporate accountability in British Columbia.

In this venture, however, Imperial is partnered with Newmont Corporation, the world’s largest gold miner and the project’s operator, which holds a strong reputation for its environmental, social, and governance (ESG) practices. The explicit consent-based framework with the Tahltan Nation, championed by Newmont, appears to be a direct institutional response to the lessons of the past. Yet, the realities of underground mining remain complex. A non-fatal incident in July, where three workers were temporarily trapped during exploratory drilling, highlights the operational dangers that demand constant vigilance. Furthermore, the project faces a potential multi-year production gap between the depletion of the open pit around 2028 and the ramp-up of the block cave in the early 2030s, a challenge that will require careful management and worker retraining.

A Multi-Generational Bet on Block Caving

The technical pivot to block caving represents a multi-billion-dollar bet on the future. This highly complex underground mining method is designed to unlock a vast, deeper ore body inaccessible by the current open pit. While requiring immense upfront capital, estimated to be around $3 billion, it transforms Red Chris from a mine with a near-term end date into a multi-generational asset that will operate for decades.

“With the authorizations granted by the Province and the support of the Tahltan Nation, the stage has been set for the development of Red Chris into a Block Cave mine,” said Brian Kynoch, President of Imperial. “These approvals are a critical step in advancing a final investment decision by the joint venture partnership... That keystone decision will unlock the potential for Red Chris to become a significant, multigenerational mine.”

Newmont’s commitment extends to modernizing the operation, with ongoing studies in partnership with the University of British Columbia to explore the electrification of the mine’s vehicle fleet. This forward-thinking approach aims to reduce both the environmental footprint and long-term operating costs. Now, all eyes are on the joint venture partners as they complete the final feasibility studies and prepare to make the ultimate decision on a project that promises to redefine mining in Canada for decades to come.
