Highlights
- Further to the Company's press release dated March 26, 2025, assays on the extension of drill hole 16TK0250 confirm a record grade massive sulphide intercept of 8.25 meters grading 12.62% Ni, 13.88% Cu, 17.95g/t PGEs+Au (23.28% NiEq or 48.87% CuEq).
- Talon is currently drilling follow up holes to test the Borehole Electromagnetic ("EM") anomaly generated from drill holes 16TK0250, 25TK0552 and 25TK0562 (see Figure 3).

"It is always thrilling to make a discovery, let alone one outside of a resource area, but for it to also be the highest grade intercept ever at Tamarack is just icing on the cake. It's also a great example of how polymetallic deposits can be so impressive. This 8.25 meter intercept would be exciting if it was only the gold values, or the PGE values, or the copper values, or the nickel values, but to have all of them together makes this intercept exceptional," said Brian Golder, Chief Exploration and Operating Officer at Talon.
Background
Since Talon's press release dated February 3, 2025, Talon's in-house exploration team continues with '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 649 meters depth in order to evaluate a subtle Borehole EM response.
- 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 (see Figure 2).
- 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.
- A Borehole EM survey conducted on the extension of drill hole 16TK0250, and drill holes 25TK0552 and 25TK0562 has identified a strong off-hole conductor using the Provus Novaminex system, which is normally a vector to high-grade mineralization (see Figure 3).

Lundin Earn-in Agreement Update
Talon and Lundin Mining Corporation ("Lundin Mining") have extended the exclusivity period until May 31, 2025 as the parties continue to work on the earn-in and related agreements ("Lundin Agreements") pursuant to which Lundin Mining may acquire up to a 70% ownership interest in the Boulderdash and Roland exploration targets, which are in close proximity to Lundin Mining's Eagle Mine and encompass approximately 33,000 acres of minerals rights out of Talon's over 400,000 acre mineral package in Michigan (see the Company's press release from March 5, 2025 for further information).
Talon is beginning to mobilize two of its drill rigs to Boulderdash and expects to begin drilling in mid-May.
QUALITY ASSURANCE, QUALITY CONTROL AND QUALIFIED PERSONS
Please see the technical report entitled "November 2022 National Instrument 43-101 Technical Report of the Tamarack North Project - Tamarack, Minnesota" with an effective date of November 2, 2022 ("November 2022 Technical Report") prepared by independent "Qualified Persons" (as that term is defined in National Instrument 43-101 ("NI 43-101")) Brian Thomas (P. Geo), Roger Jackson (P. Geo), Oliver Peters (P. Eng) and Christine Pint (P.G) for information on the QA/QC, data verification, analytical and testing procedures at the Tamarack Nickel Project. Copies are available on the Company's website (www.talonmetals.com) or on SEDAR+ at (www.sedarplus.ca). 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 consistently calculated for comparison purposes between holes because of the irregular shapes of the mineralized zones. 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.
Where used in this news release:
NiEq% = Ni% + Cu% x $4.00/$8.00 x Cu Recovery/Ni Recovery + Co% x $20.00/$8.00 x Co Recovery/Ni Recovery + Pt [g/t]/31.103 x $1,000/$8.00/22.04 x Pt Recovery/Ni Recovery + Pd [g/t]/31.103 x $1,000/$8.00/22.04 x Pd Recovery/Ni Recovery + Au [g/t]/31.103 x $2,000/$8.00/22.04 x Au Recovery/Ni Recovery + Ag [g/t]/31.103 x $20.00/$8.00/22.04 x Ag Recovery/Ni Recovery

All samples were analysed by ALS Minerals. Nickel, copper, and cobalt grades were first analysed 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).
