• Discovery coincides with the announcement of the Administration's Executive Order: "Immediate Measures to Increase American Mineral Production"

Tamarack, Minnesota--(Newsfile Corp. - March 26, 2025) - Talon Metals Corp. (TSX: TLO) (OTC Pink: TLOFF) (together with its subsidiaries, "Talon" or the "Company"), the majority owner and operator of the Tamarack Nickel-Copper-Cobalt Project ("Tamarack Nickel Copper Project") in central Minnesota and the operator of the Boulderdash nickel copper discovery and numerous high-grade nickel-copper prospects in the Upper Peninsula of Michigan, is pleased to announce a significant massive sulphide intercept measuring over 8.25 meters at the Tamarack Nickel Copper Project.

Highlights:

• Since Talon's press release dated February 3, 2025, Talon's in-house exploration team has been 'Infilling' and 'Outfilling' the Tamarack Resource Area for purposes of completing a feasibility study at the Tamarack Nickel Copper Project. This work is in support of Talon's Proposed Action (a highly detailed project description) in its Environmental Assessment Worksheet to support the preparation of an Environmental Impact Statement.
• Historic drill hole 16TK0250 was re-examined and extended from 649m depth in order to evaluate a subtle Borehole Electromagnetic ("EM") response observed in the data.
• The drill hole encountered significant mineralization at a depth of 707.75 meters, drilling 8.25 meters that was logged as 95% sulphide content (the higher the percentage of sulphide, the higher the grade of nickel at the Tamarack Nickel Copper Project).
• Notably, the intercept is located approximately 150 meters below and 50 meters south of the known massive nickel-copper mineralization within the Tamarack Resource Area, where drill hole 13TK0171 intercepted 7.74m of massive sulphide assaying 8.01% Ni, 2.87% Cu, 1.16 ppm Pd+Pt+Au or 9.51% NiEq (see the November 2022 Technical Report for further technical information). The percentage of sulphide content logged over the 7.74m interval was approximately 90%.
• Its position below the existing resource is significant, as it may represent a potential pathway or pooling of massive sulphides into a new zone that:
  • Could be laterally extensive as it's an area with a lack of drilling (see Figure 2).
  • Based on logging by Talon's in-house exploration team, could host some of the highest-grade nickel and copper mineralization discovered to date at the Tamarack Nickel Copper Project (see Figure 2).
• A Borehole EM survey conducted on the extension of 16TK0250 has identified a strong off-hole conductor, which is a typical vector to high-grade mineralization.
• Follow-up drill holes into this Borehole EM anomaly are currently underway.

Brian Goldner, COO and Chief Exploration Officer of Talon, commented on the recent results, stating: "Our exploration team has done it again, using borehole EM to guide the in-house drilling capability resulted in an exciting discovery in an area that is outside of the Tamarack resource." Goldner continued, "Our mineralization model for Tamarack is that the nickel mineralization was draining down through the intrusive system and pooled up at the bottom of the MSU near the 14TK0171 intercept. Instead of terminating there, this drilling clearly shows that the MSU continued to drain further down into a new area that currently has a lack of drilling. This type of pooling is also seen at the world's most prolific high-grade nickel producer, in Noril'sk Russia, once again showing similarities that Tamarack shares with the global giants."

"The Administration's Executive Order: "Immediate Measures to Increase American Mineral Production" from March 20, 2025, is a clear call to accelerate the discovery and development of America's critical minerals. Talon is uniquely positioned to respond - we operate the only integrated geophysics and drilling team in the United States dedicated to finding new sources of domestic nickel, copper, and cobalt. If exploration were surgery, the drill bit would be the scalpel - and Talon's geophysics team is the MRI that guides it. By combining real-time data with precision targeting, we dramatically shorten the timeline to discovery and delineation. That's the kind of speed and focus America needs right now," said Henri van Rooyen, CEO of Talon.
