Lion Copper and Gold Corp. announced Nuton LLC will provide up to US$31 million to advance the Yerington Copper Project to a Definitive Feasibility Study and mine permitting.

Summary

• Lion Copper and Gold Corp. (Lion CG) and Nuton LLC, a wholly-owned subsidiary of Rio Tinto, have agreed to proceed to Stage 3 under their option to earn-in agreement for the Yerington Copper Project.
• Nuton has exercised its option to earn-in to the Yerington Copper Project.
• Nuton will provide up to US$31 million to fund a Definitive Feasibility Study (DFS), mine permitting, and associated work programs.
• The funding aims to advance copper cathode production and support the commercial deployment of Nuton's proprietary bio-heap-leach copper extraction technology at the Yerington Copper Project.
• Previously, Nuton invested approximately US$28 million in Stages 1 and 2, which included resource definition drilling, baseline environmental studies, a preliminary economic assessment (PEA) in Q1 2024, and a Pre-Feasibility Study (PFS) in Q3 2025.

Sentiment

Score: 9

Explanation: The announcement signifies a major positive milestone with significant funding secured from a major industry player (Rio Tinto subsidiary) for a critical development stage, substantially de-risking the project and accelerating its path to production. This is a strong vote of confidence in the project's viability.

Positives

• Nuton's decision to advance to Stage 3 and exercise its earn-in option demonstrates strong confidence in the Yerington Copper Project's potential.
• Securing up to US$31 million in funding from Nuton significantly de-risks the project's development, covering the costs for the Definitive Feasibility Study and mine permitting.
• The project aims to accelerate domestic copper cathode production, which is crucial for supporting the U.S. critical mineral copper supply chain.
• Nuton's proprietary bio-heap-leach technology offers the potential for economic copper extraction from primary sulfide resources with market-leading recovery rates and a low environmental footprint.
• Lion CG has invested two decades in de-risking the Yerington project, building a deep understanding of the resource, the community, and the path to responsible development.

Risks

• Risks related to mineral exploration and development.
• Potential for permitting delays.
• Changes in regulatory frameworks.
• Cost escalation during project development.
• Inability to secure future financing beyond the current Stage 3 commitment.
• Technical challenges associated with the deployment of new extraction technologies, such as Nuton Technology, at scale.
• Commodity price fluctuations for copper.
• Issues related to community relations.
• Supply chain constraints affecting project development.
• No assurance that Stage 3 will be completed as contemplated, or at all.
• No assurance that the Yerington Project will ultimately reach commercial production.

Future Outlook

The parties will undertake a Definitive Feasibility Study, submit final permitting and regulatory applications, conduct detailed engineering design and cost estimation, and evaluate scaling opportunities for the Yerington copper district. The project aims to accelerate Yerington toward potential production and advance a scalable, lower-impact copper solution to meet domestic refined copper supply needs.

Management Comments

• John Banning, CEO of Lion CG, commented: "Nuton's decision to advance to Stage 3 marks a pivotal milestone for the Yerington Copper Project's direction and timeline as it moves forward with mine development, permitting and general project derisking and a strong vote of confidence in both our team and the district's potential as a meaningful near-term domestic copper supplier."
• John Banning, CEO of Lion CG, stated: "With two decades of investment and de-risking at Yerington, Lion CG has built a deep understanding of the resource, the community, and the path to responsible development. Nuton's continued commitment reinforces this shared confidence and brings additional technology, expertise, and momentum as we progress permitting, engineering, and the technical work ahead. Together, we are accelerating Yerington toward potential production and advancing a scalable, lower-impact copper solution at a time when domestic refined copper supply has never been more important."
• Adam Burley, Nuton's Chief Executive Officer, added: "Nuton's decision to advance the Yerington Copper Project reflects our confidence in its potential as a major copper-producing district. Lion CG's extensive work and commitment have significantly derisked the project and built a strong foundation of resource knowledge, community engagement, and responsible development principles. Together, we aim to meet rising copper demand with innovative, scalable, and low-impact solutions."

Industry Context

This announcement aligns with the growing global demand for copper, particularly for critical minerals and strengthening domestic supply chains. The integration of Nuton's proprietary bio-heap-leach technology positions the Yerington project as a potentially lower-impact and more sustainable solution, addressing environmental concerns prevalent in the mining industry. The focus on domestic production in Nevada supports national strategic goals for critical mineral independence and supply security.

Comparison to Industry Standards

• Nuton's proprietary copper leaching technology aims to achieve "market-leading recovery rates" from primary sulfide resources, potentially outperforming conventional methods.
• Nuton's ambition is to produce the "world's lowest footprint copper" while having at least one positive impact across five pillars: water, energy, land, materials, and society, setting a high standard for environmental responsibility.
• The Yerington Copper Project is described as a "long-life, low-strip-ratio, brownfield-advantaged" project, suggesting favorable operational characteristics and reduced initial development complexities compared to new greenfield developments.

Stakeholder Impact

• Shareholders: Positive impact due to significant project de-risking, substantial funding from a reputable partner, and an accelerated path to potential production, which could enhance company valuation.
• Employees: Potential for increased employment opportunities as the project advances through DFS, permitting, and eventual development phases.
• Customers: Potential for a future domestic supply of copper cathode, contributing to supply chain stability and security.
• Local Community (Yerington, Nevada): Potential for economic benefits through job creation, local investment, and a commitment to responsible development and community engagement.
• Regulatory Authorities: Ongoing engagement with federal and state regulatory bodies through the submission of final permitting and regulatory applications.

Next Steps

• Undertake a Definitive Feasibility Study (DFS), incorporating results from the recent Pre-Feasibility Study and final optimization of mining, metallurgy, hydrology, and engineering studies.
• Submit final permitting and regulatory applications required under U.S. federal and Nevada state law.
• Conduct detailed engineering design, cost estimation, and development planning, with the objective of positioning the project for efficient and effective commercial production.
• Perform additional evaluation studies of the Yerington copper district's scaling opportunities.
• Provide timely updates regarding key feasibility and permitting milestones, as well as any potential commercial and investment agreements as the project advances.

Key Dates

Recommendation

The securing of up to US$31 million in funding from Nuton (a Rio Tinto subsidiary) for the Definitive Feasibility Study and mine permitting is a highly significant de-risking event for the Yerington Copper Project. This commitment, coupled with Nuton exercising its earn-in option, signals strong confidence from a major industry player and substantially accelerates the project's path towards commercial production. The project's focus on domestic copper supply and innovative, lower-impact technology further enhances its strategic value. This development significantly improves the project's viability and future prospects, making the stock a strong buy.
