Talon Metals to Acquire Lundin Mining's Eagle

Mine and Humboldt Mill Operations, Creating a

Multi-Asset U.S. Nickel-Copper Company

Tamarack, Minnesota and L'Anse, Michigan--(Newsfile Corp. - December 18, 2025) - Talon Metals

Corp. (TSX: TLO) (OTCID: TLOFF) (together with its subsidiaries, "

Talon

" or the "

Company

") is

pleased to announce the signing of a share purchase agreement (the "

Share Purchase Agreement

")

with Lundin Mining Corporation (TSX: LUN) (Stockholm: LUMI) ("

Lundin Mining

"). The Share Purchase

Agreement provides for a transaction (the "

Transaction

") that will result in the combination of

Lundin

Mining's producing Eagle Mine and associated Humboldt Mill with Talon's interest in the Tamarack

Nickel-Copper-Cobalt Project (the "

Tamarack Nickel-Copper Project

") and a prospective exploration

land package of over 400,000 acres in Michigan, which includes the Boulderdash nickel/copper

discovery 8-miles from the Eagle Mine, and Talon's proposed North Dakota Beulah Minerals Processing

Facility (the "

BMPF

").

KEY TRANSACTION HIGHLIGHTS

Talon will acquire 100% of the Eagle Mine and Humboldt Mill operations.

Talon will issue 275,152,232 common shares to Lundin Mining, representing 18.73% of the

Company on a non-diluted basis after the Concurrent Private Placement by the Lundin Family

Trust. Together with Lundin Mining's ownership interest in Talon before the Transaction, Lundin

Mining will own 19.99% of Talon after closing of the Transaction on a non-diluted basis.

A concurrent Private Placement with the Lundin Family Trust for approximately US$5.6 million in

gross proceeds, will result in the Lundin Family Trust owning approximately 1.26% of Talon after

closing of the Transaction on a non-diluted basis.

Jack Lundin and Juan Andrés Morel, the CEO and COO, respectively, of Lundin Mining will join the

Talon Board.

Lundin Mining will maintain all financial assurances for the Eagle Mine and Humboldt Mill

reclamation until Talon's Board approves development of a new mine, provided that Talon uses

commercially reasonable efforts to amend or replace such financial assurances.

CREATING A UNIFIED, MULTI-ASSET U.S. NICKEL PLATFORM

"

This transaction brings together the positive cash-flow-generating Eagle Mine and Humboldt Mill, the

proven operating experience of the Eagle and Humboldt teams, and Talon's in-house exploration

capabilities to create the only operating primary nickel-copper company in the United States with

expansion potential

," said Henri van Rooyen, Chief Executive Officer of Talon. "

The integration enables

our combined team to advance our four strategic priorities in parallel - extending the Eagle mine life,

accelerating exploration in Michigan and in Minnesota, advancing permitting at the Tamarack Nickel-

Copper Project and the Beulah Minerals Processing Facility, and progressing engineering towards

feasibility study and construction."

The unified Talon team will deploy the positive cash flow from the Eagle Mine and Humboldt Mill,

together with an estimated US$27 million of cash and cash equivalents, towards:

Extending Eagle Mine Life Through Modern Practices

The Eagle Mine and Humboldt Mill exemplify modern mining, built and operated to the highest standards

of safety and environmental responsibility in Michigan's Upper Peninsula. Ongoing efficiency

improvements and optimizations has the potential to extend the mine's life to maintain full capacity at the

Humboldt Mill.

Accelerating Exploration in Michigan and at Tamarack

With the Humboldt Mill ideally positioned to process ore from Talon's Michigan discoveries such as

Boulderdash - just 8 miles from the Eagle Mine - Talon's in-house exploration team, responsible for five

discoveries in five years, plans to execute its most ambitious exploration program to date in 2026.

Advancing Tamarack and BMPF Environmental Review and Permitting

Building on the successful permitting and exemplary environmental performance of the Eagle Mine and

Humboldt Mill, the unified team combines Eagle's operational experience with Talon's environmental

specialists to advance the Tamarack Nickel-Copper Project through environmental review and

permitting towards construction.

Progressing Engineering for the Future Tamarack Mine and BMPF

Following the iterative design process of the proposed Tamarack mine, driven by two years of

collaboration with the Minnesota Department of Natural Resources and participating Tribal governments,

Talon is proposing a "mine of the future" with all potential environmental impacts expected to be

controlled within one fully enclosed facility. The proven Eagle team, with its track record in mine design,

engineering, construction, and operations, will now integrate with the Talon team to complete the

feasibility study in conjunction with environmental review and permitting, improving confidence in the

design and long-term operability of these assets.

"

Over the last decade, American policymakers have recognized that dependence on foreign sources

for critical minerals is a national security risk

," said Henri van Rooyen, Talon CEO. "

This transaction is

a direct response, uniting modern nickel mining and processing operations with the Tamarack Nickel-

Copper Project and exploration assets, including the Boulderdash discovery 8-miles from the Eagle

mine, to ensure a domestic supply of nickel and other critical minerals for defense, energy and

advanced technology manufacturing

."

ABOUT THE TRANSACTION

Pursuant to the terms of the Share Purchase Agreement, Talon will acquire 100% of the outstanding

shares of Lundin Mining US Ltd. ("

Lundin SubCo

"), a wholly-owned subsidiary of Lundin Mining, which

owns the Eagle Mine and Humboldt Mill, in exchange for: (i) 275,152,232 Talon Shares which will result

in Lundin Mining increasing its interest in Talon from 1.57% to 19.99% of the outstanding Talon Shares

on a non-diluted basis, based on the number of Talon Shares that are issued and outstanding as of the

date of the Share Purchase Agreement (and assuming the issuance of Talon Shares pursuant to the

Concurrent Private Placement); and (ii) the grant of a production payment royalty (the "

Production

Payment Royalty

") on ore from sources other than the Eagle Mine that is processed through the

Humboldt Mill at a rate of US$1.00 per tonne, up to a maximum aggregate payment of US$20.0 million,

representing 20 million tonnes of ore.

The Share Purchase Agreement also provides that, concurrently with closing of the Transaction, Talon

and Lundin Mining will enter into an investor rights agreement (the "

Investor Rights Agreement

") and a

lock-up agreement (the "

Lock-Up Agreement

"). The Investor Rights Agreement will provide Lundin

Mining with certain board nomination rights, as well as participation rights in respect of future equity

issuances by Talon to allow it to maintain its ownership interest, for so long as Lundin Mining has

beneficial ownership of at least 10% of the Talon Shares. The Lock-Up Agreement will provide for

limitations on sales of Talon Shares by Lundin Mining during the two-year period following the date of the

Lock-Up Agreement. The Lock-Up Agreement will also provide that Lundin Mining will not acquire

beneficial ownership of more than 19.99% of the Talon Shares during the one-year period following the

date of the Lock-Up Agreement, subject to certain exceptions.

In addition, Lundin Mining has agreed to maintain and bear the cost of all financial assurances provided

in respect of mining and reclamation operations of the Eagle Mine and Humboldt Mill until the board of

directors of Talon (the "

Talon Board

") makes a "Positive Final Investment Decision" in respect of

developing a mine on any of Talon's properties, provided that Talon uses commercially reasonable

efforts to amend or replace such financial assurances.

Director and Officer Changes

At closing of the Transaction, the Talon Board will be reconstituted to consist of ten directors, including

Jack Lundin and Juan Andrés Morel, the CEO and COO, respectively, of Lundin Mining and seven of the

eight directors currently on the Talon Board. Darby Stacey, the current Managing Director of Eagle Mine,

will be appointed to the Talon Board and appointed as CEO of Talon, overseeing the operations of the

combined assets, with Henri van Rooyen being appointed Executive Chairman. On closing of the

Transaction, Warren Newfield will be stepping down from the Talon Board and as Executive Chairman of

Talon.

Henri van Rooyen, Talon CEO said: "

On behalf of Talon, I would like to sincerely thank Warren

Newfield for his many years of support as Executive Chairman, during which Talon achieved

numerous important milestones that created significant value for shareholders

."

Concurrent Private Placement

Concurrently with the signing of the Share Purchase Agreement, Talon signed a subscription agreement

with a trust settled by the late Adolf H. Lundin (the "

Lundin Family Trust

") pursuant to which the Lundin

Family Trust agreed to purchase 18,555,783 Talon Shares, at a price of C$0.4194 per Talon Share (the

"

Issue Price

"), which is the deemed value of the Talon Shares to be issued to Lundin Mining in

connection with the Transaction, on a private placement basis for gross proceeds of approximately

C$7.8 million or US$5.6 million (the "

Concurrent Private Placement

").

The gross proceeds of the Concurrent Private Placement will be used to fund transition costs, due

diligence costs, acquisition costs, and integration costs.

The Concurrent Private Placement is expected to close concurrently with the closing of the Transaction. It

is also expected that Talon and the Lundin Family Trust will enter into an agreement in connection with

the closing of the Concurrent Private Placement that provides the Lundin Family Trust with a contractual

right in respect of future equity offerings by Talon, so it has the ability to maintain its ownership interest in

Talon.

Share Consolidation

Under the terms of the Share Purchase Agreement, Talon agreed to complete a consolidation of the

Talon Shares (the "

Consolidation

") as soon as practicable after the closing of the Transaction. The

Consolidation would be on the basis of one post-consolidation Talon Share for every ten pre-

consolidation Talon Shares, as approved by the shareholders of Talon at the annual and special meeting

of shareholders held on June 25, 2025. The Talon Board has approved the Consolidation and the date

the Talon Board has determined to implement the Consolidation will be announced in connection with

closing of the Transaction, together with additional details about the Consolidation.

Additional Transaction Details

to the approval of the Toronto Stock Exchange (the "

TSX

customary closing conditions.
