Highlights

• Drill core samples from the Tamarack Nickel Copper Project's Vault Zone discovery will be accessioned into the collection of the Smithsonian National Museum of Natural History.

• Two 20 centimeter drill core samples taken within the interval from 796.5 meters to 798 meters in drill hole 25TK0563 grading 19.4% Ni, 13.8% Cu, 0.12% Co, 15.85 g/t Au, 31.7 g/t Pt, 13.6 g/t Pd, and 45.2 g/t Ag (40.81% NiEq or 81.30% CuEq) will be hand delivered to the Smithsonian National Museum of Natural History later this fall (see the Company's press release from June 5, 2025 for further technical information).

• This drill core represents a significant scientific sample from within the 1.1-billion-year-old Midcontinent Rift.

Ongoing Progress and Momentum with Department of War Support

• With continuing support from the Department of War ("DOW") since 2023 via funds awarded through Title III of the Defense Production Act, Talon has been accelerating rapid discovery and delineation of domestic nickel, copper, and other critical minerals in Minnesota and Michigan (see the Company's press release from September 12, 2023 for further details).

• Since that time, Talon has utilized its integrated exploration team to successfully make new discoveries in both Minnesota and Michigan.

• As the Tamarack Nickel Copper Project is now in the feasibility study phase, existing DOW funding will now support the feasibility study and the requisite engineering and environmental study inputs. The feasibility study is a critical path requirement to support the environmental review and permitting process in advance of construction.

"The ability to ensure the long-term preservation of this Tamarack sample by the Smithsonian is an honor for our team, and highlights the scientific significance of this discovery," said Henri van Rooyen, CEO of Talon. "At the same time, the Department of War is helping to ensure that we can continue to move this project forward to production—so that America can secure its own supply of nickel, copper, and platinum group metals," van Rooyen added. "It is clear that Tamarack nickel is both a scientific treasure and a strategic resource for the United States."

Congressman Stauber added, "This discovery is truly extraordinary—in not just one, but several U.S. critical minerals vital to national security, with grades that rank among the best in the world. Even the by-products are world-class. That's why it's headed to the Smithsonian, and why it's a game-changer for America's resource independence."

Talon Board Update

After careful consideration, Mr. Sean Werger has decided to step down from Talon Metals Corp.'s board of directors in order to dedicate more time to his professional commitments. Mr. Werger stated, "I have greatly valued my time at Talon and on the Board. I remain a strong supporter of the Company and wish the team every success moving forward." The entire Talon team thanks Mr. Werger for his insight and leadership during his tenure.
