Talon Metals Drills Significant Nickel-Copper

Mineralization Intercept at Tamarack During

Feasibility Study Drilling

Intercept is outside of the Tamarack Resource Area at shallow

depths in the CGO East Zone

Tamarack, Minnesota--(Newsfile Corp. - April 15, 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, is pleased to announce a mixed massive sulphide intercept in the CGO East Zone at the

Tamarack Nickel Copper Project measuring 16.09 meters.

Highlights

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.

Once again, this exploration work has resulted in new success with

drill hole 25TK0561

, that was

targeting a Borehole Electromagnetic ("

BHEM

") model below the Tamarack Resource Area,

encountering significant mineralization at a depth of 359.16 meters, drilling

16.09 meters

(See

Figure 1) logged as 10% to 80% sulphide content (the higher the percentage of sulphide, the

higher the grade of nickel at the Tamarack Nickel Copper Project).

Its position below the existing shallow part of the Tamarack Resource Area is important as it may

represent a waterfall draining the CGO East Zone mineralization, similar to the waterfall in the

CGO West Zone, where the mineralization orientation changes from near horizontal to near vertical

(See Figure 2 (plan view of cross section A-A') and Figure 3 (cross section showing the potential

CGO East Zone waterfall)).

As is the case with CGO West Zone waterfall, a CGO East Zone waterfall of mineralization has the

potential to add tonnage early in the Tamarack mine life, with minimal additional cost.

Brian Goldner, COO and Chief Exploration Officer of Talon, commented on the recent results, stating:

"

Not to sound like a broken record, but once again, borehole EM pointed to another great intercept,

this time in CGO East. The really exciting part of this intercept is that the Massive Sulphide Unit

appears to be plunging down below the CGO intrusion which begs the question, if it is draining where

does it pool. Both the CGO East Zone and CGO West Zone, and the results from last month's

intercept in the 138 Zone, show strong evidence that the Tamarack mineralization is draining to depth

into areas with limited drilling.

"

"The timing of this record CGO East Zone intercept at shallow depth could not be more aligned with

the Administration's Executive Order: "Immediate Measures to Increase American Mineral

Production" from March 20, 2025," said Henri van Rooyen, CEO of Talon. "Together with last month's

exceptional 8.25-meter intercept in drill hole 16TK0250, the Tamarack Nickel Copper Project is

clearly demonstrating the potential for additional high-grade nickel and copper mineralization beyond

the current known resource footprint."

Geophysical Innovation

:

Drill hole 25TK0561 targeted a BHEM model that was developed using

Provus, a unique 3-D BHEM software package developed by Novaminex, in partnership with Talon (see

Figure 4).

A follow-up BHEM survey has been conducted, and Talon is reviewing the area to determine if

any other historical holes should be extended to look for additional mineralization at depth.

Brian Bengert, VP of Geophysics, stated:

"The Novaminex Provus EM modelling software is changing

our understanding of complex conductivity structures that are the focus of major nickel massive

sulphide deposits. While industry standard EM modelling should only be applied to a single borehole

at a time, Provus can model entire conductive systems from multiple holes simultaneously.

In this

case, we were able to model a complicated electromagnetic conductor that was winding its way

between our boreholes beneath the CGO East mineralization. This was not apparent in the individual

plate models of traditional modelling and the target yielded some great results."

a single ribbon model, better fitting the BHEM response with a conductive system rather than

the industry standard of modelling plates to individual drill holes.

Length refers to drill hole length and not True Width.

True Width is unknown at the time of publication.

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).

For Ni and Cu recoveries, please refer to the formulae in the November 2022 Technical Report. Recovery of Ni to the Cu concentrate was excluded

from the NiEq calculation.

The following recoveries were used for the other metals: 64.1% for Co, 82.5% for Pt, 69.3% for Pd and 72.6% for Au.
