TALON METALS MAKES SECOND HISTORIC DISCOVERY IN A MONTH AT TAMARACK: 34.9 METERS OF MASSIVE NICKEL MINERALIZATION INTERCEPTED IN A NEW ZONE

Most Significant Massive Nickel Mineralization Intercepted in Tamarack History in a Second New Zone Below the Tamarack Resource Area

Tamarack, Minnesota (May 12, 2025) – Talon Metals Corp. (together with its subsidiaries, “Talon” or the “Company”) (TSX:TLO/OTC:TLOFF), the majority owner and operator of the Tamarack Nickel-Copper-Cobalt Project (“Tamarack Nickel Copper Project”) in central Minnesota, is pleased to announce a historic massive sulphide (“MSU”) intercept measuring a cumulative 34.9 meters at the Tamarack Nickel Copper Project.

Highlights:

  • Drill hole 25TK0563 intercepted a cumulative length of 34.9 meters of massive nickel mineralization starting at 762.34 meters (over a total length of 47.33 meters).
  • The drill hole was targeting a series of Borehole Electromagnetic (“BHEM”) anomalies identified from previous drill holes 25TK0562 and 16TK0250.
  • The previous record drilling thickness of MSU at the Tamarack Nickel Copper Project was 23.44 meters from drill hole 21TK0380 (see press release dated September 22, 2022).
  • The MSU in drill hole 25TK0563 appears to be very similar to the MSU in drill hole 16TK0250 extension suggesting grades may be similar (see Table 2).
  • Disseminated and vein mineralization above the MSU in drill hole 25TK0563 shows chalcocite and bornite suggesting high copper content similar to drill hole 16TK0250.
  • Drill hole 25TK0563 represents an approximate 68 meter step-out to the east from the intercept in drill hole 16TK0250.
  • BHEM surveys are currently being conducted on drill hole 25TK0563.

“In my 19 years working on the Tamarack Project, I’ve never seen anything like this. This 34.9-meter intercept of high-grade massive sulphide isn’t just the longest ever recorded at Tamarack — it’s a defining moment. It confirms what we’ve believed all along: that Tamarack is a truly world-class system. This project is essential to America’s critical mineral independence, offering a domestic source of nickel and copper at a time when the United States needs it most,” said Brian Goldner, Talon’s Chief Exploration and Operations Officer.
