Amended Environmental Assessment Worksheet Submitted, Johnson to Lead External Affairs Team

Tamarack, Minnesota--(Newsfile Corp. - December 19, 2024) - Talon Metals Corp. (TSX: TLO) (OTC Pink: TLOFF) through its subsidiary Talon Nickel (USA) LLC ("Talon" or the "Company"), submitted an amended Environmental Assessment Worksheet ("EAW") to the Minnesota Department of Natural Resources for the State's Environmental Impact Statement scoping process for the Tamarack Nickel-Copper Project, a proposed small-footprint, high-grade underground nickel mine that would be located near the City of Tamarack in Aitkin County, Minnesota (the "Tamarack Mining Project").

Talon first began the review process in June 2023 (see the Company's press release dated June 21, 2023). Since that time, the proposed Tamarack Mining Project has gone through two rounds of comments with the Minnesota regulatory agencies and participating tribal governments/organizations. After receiving the second round of comments on the EAW in February 2024, Talon has taken steps to investigate and propose engineered solutions to potential concerns. While this process has taken several months, the responsive engineering work underscores the Company's commitment to incorporating meaningful improvements that not only address technical requirements but also respond to broader stakeholder interests and concerns.

The amended EAW covers several key conceptual aspects of the Project for scoping.

Consolidation of operations into a single enclosed building

This proposed change:

• Eliminates outdoor waste rock stockpiles, significantly reducing the risk of fugitive dust outside of a controlled environment.
• Simplifies stormwater management by removing the need for extensive systems to handle outdoor contact stormwater from the Tamarack Mine Project.
• Reduces the developed footprint, which is now over 10 acres smaller than in the original design, reflecting the Company's focus on minimizing environmental impacts while maintaining operational goals.
• Significantly diminishes nighttime light pollution preserving the natural dark-sky quality of the area.
• Reduces the sound generated by future operations further limiting the project's sensory impact on the surrounding environment and community as the building serves as an effective noise barrier.

Further proposed enhancements

• Transitioning from a Tunnel Boring Machine (TBM) method that would require a looped tunnel, to a single decline ramp. This proposed change will decrease the volume of development rock generated and reduce material handling demands.
• Shifting from manifest trains to unit trains to optimize rail transportation, reducing the frequency of shipments from the site (a single unit train equates to approximately three manifest trains).

"These proposed updates reflect Talon's ongoing commitment to listening and responding to feedback, ensuring that the Tamarack Mine Project evolves in a manner that addresses both technical requirements and the expectations of those invested in the project's success. By prioritizing environment protection, operational sustainability, and community well-being, this amended EAW underscores Talon's dedication to advancing the project responsibly," said Chris Wallace, Vice President of Environmental and Permitting for Talon.

Jessica Johnson, Talon's Vice President, External Affairs also stated, "Talon is excited to continue the environmental review process, where the project design will go through further evaluation. Soon the process will encourage formal public participation through providing comments on the proposed project. These comments can further shape and refine the project design."
