110.3 Meters of 2.24% CuEq (0.88% NiEq) Starting at a Depth of Only 9.54 Meters, and an Intercept of 2.35 Meters of 10.47% Copper Equivalent (4.13% NiEq)

Tamarack, Minnesota--(Newsfile Corp. - February 27, 2025) - Talon Metals Corp. (TSX: TLO) (OTC Pink: TLOFF) ("Talon" or the "Company") is pleased to announce additional assays from its Boulderdash discovery in Michigan's Upper Peninsula. Most notably, drill hole 24BD0003 intercepted 110.3 meters of nickel-copper sulphide mineralization beginning at 9.54 meters depth assaying 0.57% Ni and 0.50% Cu (2.24% CuEq, 0.88% NiEq), a 40% increase in grade compared to discovery drill hole 24BD0001 (see the Company's press release dated October 24, 2024).

Highlights

• New assays at Boulderdash confirm nickel and copper grades, including:

• Drill hole 24BD0003: 110.3 meters of nickel-copper mineralization starting at 9.54 meters depth assaying 0.57% Ni and 0.50% Cu (2.24% CuEq, 0.88% NiEq)

• Drill hole 24BD0008: 154.25 meters of nickel-copper mineralization starting at 10.75 meters depth assaying 0.48% Ni, 0.44% Cu (1.93% CuEq, 0.76% NiEq) and 2.35 meters of nickel-copper massive sulphide mineralization starting at 182.11 meters depth assaying 2.33% Ni, 2.95% Cu (10.47% CuEq, 4.13% NiEq)

• Boulderdash is situated just 8 miles northwest of the Eagle Nickel Mine, currently the only operating nickel mine in the U.S.

"Additional drilling at Boulderdash has generated longer and higher grade nickel-copper intercepts than discovery hole 24BD0001", said Brian Goldner, Talon's Chief Exploration Officer. Goldner continued, "Drill hole 24BD0008 intersected the first high-grade massive sulphide accumulation at a shallow depth of 182 meters. This exploration progression shows uncanny resemblance to the discovery history of the nearby Eagle nickel deposit which started with intercepts of net textured mineralization and progressed to massive sulphides before culminating in a deposit. As it stands, Boulderdash is now shaping up to have two exploration targets: a massive sulphide body at depth and a near-surface target starting at a depth of just 9 meters. Next steps are to explore for lateral extensions of the near-surface mineralization and to locate more of the high-grade massive sulphide mineralization".

These Boulderdash drill holes are located within the land package that is part of the earn-in agreement with UPX Minerals Inc. (a wholly-owned subsidiary of Sweetwater Royalties), whereby Talon has the right to acquire up to an 80% ownership interest in approximately 400,000 acres located in the Upper Peninsula of the State of Michigan.

2025 Boulderdash Exploration Work Plan

The Eagle and Eagle East deposits are being used as exploration models due to their (i) proximity (only 8 miles away), and (ii) geologic similarities. The model is a near vertical dike with net textured mineralization above leading downward to sub horizontal massive sulphide sheets intruding into the metasediment rocks.

Talon's 2025 Boulderdash exploration work plan will focus on two exploration pathways, lateral extension of the near-surface mineralization and progressive exploration down the dike at depth. It is expected that Talon's in-house drilling and geophysics teams will be focused on this work after spring breakup. Talon is currently drilling at the Tamarack Nickel Project with three in house drill rigs to complete some infill drilling prior to mobilizing the drill rigs to Boulderdash.

QUALITY ASSURANCE, QUALITY CONTROL AND QUALIFIED PERSON

Nickel, copper, and cobalt grades were first analyzed by a 4-acid digestion and ICP AES (ME-MS61). Grades reporting greater than 0.25% Ni and/or 0.1% Cu, using ME-MS61, trigger a sodium peroxide fusion with ICP-AES finish (ICP81). Platinum, palladium and gold are initially analyzed by a 50g fire assay with an ICP-MS finish (PGM-MS24). Any samples reporting >1g/t Pt or Pd trigger an over-limit analysis by ICP-AES finish (PGM-ICP27) and any samples reporting >1g/t Au trigger an over-limit analysis by AAS (Au-AA26). The laboratory used is ALS Minerals who is independent of the Company.

Lengths are drill intersections and not necessarily true widths. True widths cannot be calculated at this time due to the unknown geometry of the mineralization. Drill intersections have been independently selected by Talon. Drill composites have been independently calculated by Talon. The geological interpretations in this news release are solely those of the Company. The locations and distances highlighted on all maps in this news release are approximate.

Dr. Etienne Dinel, Vice President, Geology of Talon, is a Qualified Person within the meaning of NI 43-101. Dr. Dinel is satisfied that the analytical and testing procedures used are standard industry operating procedures and methodologies, and he has reviewed, approved and verified the technical information disclosed in this news release, including sampling, analytical and test data underlying the technical information.
