Moon River Moly Ltd. Files Technical Report for Davidson Mine PEA

Moon River Moly Ltd. has officially filed a comprehensive technical report related to the Preliminary Economic Assessment (“PEA”) of its Davidson Mine project, reinforcing the company’s progress in advancing one of its most significant assets. This filing marks an important milestone in project development and provides transparent economic analysis under recognized reporting standards.

Overview of the Technical Report Filing

On February 6, 2026, Moon River Moly Ltd. announced the filing of the National Instrument 43-101 Technical Report for the Davidson Mine Preliminary Economic Assessment (the “Davidson Mine Technical Report”), which carries an effective date of December 23, 2025. This detailed document has been prepared following the stringent disclosure and technical requirements set by National Instrument 43-101 — a widely accepted standard in Canadian mineral project reporting.

The technical report has been made publicly available through the company’s profile on SEDAR+ (the System for Electronic Document Analysis and Retrieval) and through the official Moon River Moly Ltd. website, allowing investors, analysts, and other stakeholders to review it directly.

What the Davidson Mine Technical Report Includes

This Technical Report provides a detailed economic analysis of the Davidson Mine project. It assesses key parameters such as estimated capital costs, production profiles, projected revenues, operating costs, and potential environmental and infrastructure considerations. The information in the report aligns with disclosures previously shared by the company earlier in December 2025, meaning there are no material discrepancies compared to those prior summaries.

Prepared by A-Z Mining Professionals Ltd. (AMPL), this independent analysis was reviewed and approved by qualified technical experts. Mr. Brian LeBlanc, P.Eng., President of AMPL, acted as the Qualified Person (QP) responsible for overseeing and validating all technical content within the report — a requirement under NI 43-101 standards for transparency and accuracy.

About the Davidson Mine Project

The Davidson Mine is a cornerstone project for Moon River Moly Ltd., situated near Smithers, British Columbia. It hosts a substantial molybdenum-tungsten and molybdenum-copper-tungsten deposit — one of the key critical mineral resources targeted for development.

With evolving market conditions and rising demand for critical minerals such as molybdenum, copper, and tungsten, the Davidson project represents a strategic asset for Moon River. The recently updated PEA (dated December 23, 2025) highlighted enhanced economic performance compared to prior reports — including higher throughput estimates, potential by-product credits, and an extended mine life outlook.

Project Economic Highlights from the Updated PEA

Although the detailed Technical Report itself contains extensive economic modeling, summary statistics from the updated PEA can provide context to the scope and potential of Davidson Mine:

• Net Present Value (NPV): Estimated pre-tax value of approximately $1.747 billion and after-tax value of about $1.034 billion, assuming an 8 % discount rate.
• Internal Rate of Return (IRR): A strong projected IRR of 42 % before taxes and 32 % after taxes.
• Mine Life: The PEA envisions roughly a 20-year operating life with a mill throughput of about 10,000 tonnes per day.
• Production: Annual production estimates include approximately 6 million kg of molybdenum, 0.68 million kg of copper, and 151.7 tonnes of tungsten.
• Carbon Footprint: The envisioned mine design emphasizes environmentally responsible operations by using battery-powered equipment and minimizing surface impacts.

The Strategic Importance of Filing the Technical Report

Filing the NI 43-101 Technical Report represents a key regulatory and operational step for Moon River Moly Ltd. It demonstrates the company’s commitment to high standards of financial disclosure and technical transparency for project evaluation.

For investors, industry analysts, and potential partners, having access to a detailed NI 43-101 report provides confidence that the economic potential of the Davidson Mine is backed by rigorous technical analysis and assumptions vetted by independent qualified professionals.

Company Profile and Development Strategy

Moon River Moly Ltd. is a Canadian resource development company focused on the acquisition, exploration, and advancement of mineral projects — notably the Davidson property and its strategic interest in the Endako Mine Complex in British Columbia.

The company’s approach incorporates both the development of its flagship Davidson project and participation in other assets like the Endako molybdenum mine, which Moon River holds a meaningful ownership stake in. These dual efforts reflect a broader strategy to benefit from diversified exposure to high-value mineral resources in a mining-friendly jurisdiction.

Qualified Persons and Compliance

Under NI 43-101 regulations, technical reports must be prepared or supervised by qualified professionals to ensure that geological and economic information meets regulatory standards for public dissemination. Mr. Brian LeBlanc, P.Eng., not only supervised but reviewed and approved the technical content within this latest report, adding credibility to the project’s data and feasibility.

Looking Ahead

With the technical report now filed and publicly accessible, Moon River Moly Ltd. can focus on continued exploration, stakeholder engagement, and potential next steps toward advancing the Davidson Mine toward future development stages. Continued engagement with local communities, First Nations, regulators, and investors will be key to moving this project from a strong economic outlook toward execution in the years ahead.

Investors and interested parties are encouraged to review the full technical report available on SEDAR+ or through Moon River’s official website for a complete understanding of the underlying assumptions, data, and risk factors associated with the project.
