Lundin Mining Announces Vicuña Integrated Technical Study Results

Highlighting a World-Class Mining District

Vancouver, February 16, 2026 (TSX: LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation (“Lundin

Mining” or the “Company”) is pleased to announce the results of the integrated technical study (the Preliminary

Economic Assessment "PEA" or the "Study") for the Vicuña project (the " Vicuña Project" or the “Project” ). The

Vicuña Project is comprised of the Filo del Sol deposit and the Josemaria deposit and is held by Vicu ña Corp.

(“Vicuña”), a 50/50 joint arrangement between Lundin Mining and BHP . Unless otherwise indicated, all dollar

amounts are stated in United States dollars ("$") and presented on a 100% basis.

Jack Lundin, President and CEO of Lundin Mining, commented, "The publication of these impressive results

marks a significant milestone and a major step towards advancing the Vicuña Project to a sanction decision. The

progress achieved since the formation of Vicuña Corp . has been exceptional, and this Study establishes a solid

foundation for moving the Project forward while continuing to refine later stages and drive further improvements

in cost, schedule, and production.

“The Study outlines a project that would rank among the top five copper, gold, and silver mines globally. A staged

development approach provides a disciplined pathway to unlock the full value of the district, enabling sequenced

capital deployment, effective risk management, and ongoing optimization while delivering substantial, long -life

copper production growth over multiple decades.

“With the announcement on Thursday for commitments to upsize our credit facility to $4.5 billion, Lundin Mining

is fully funded for the initial phase of construction, and we remain on course to achieve our goal of becoming a

top-ten global copper producer with annual production of over 500,000 tonnes of copper and 550,000 ounces of

gold once Vicuña is in full operation.”

Study Highlights

The development of the Vicuña district is envisioned in a staged approach. Stage 1 encompasses a sulphide mill

and the Josemaria deposit, establishing an initial open pit mine and concentrator designed for future expansion

to accelerate first production and early cash flow. Stage 2 builds on this foundation by developing the Filo del Sol

leachable oxides and a corresponding SX /EW plant for copper, gold and silver recovery. Stage 3 represents the

long-term maturation of the district through expansion of the concentrator and development of the Filo del Sol

sulphide deposit , enabling peak, sustained production , positioning the Vicuña Project as a long -life, globally

significant copper operation. Stage 3 also integrates key district infrastructure, including a desalination plant and

associated pipeline, and return concentrate slurry pipeline, to support expansion of the district.

• Potential to be a top five copper, gold, and silver mine: Average annual production of 400,000 tonnes

copper, 700,000 ounces (“oz”) gold and 22 million ounces (“Moz”) silver over the first 25 full years of

operation.

• Peak production of +500 ktpa copper: Average production over a ten -year period of over 500,000

tonnes copper, 800,000 oz gold and 20 Moz silver or 800,000 tonnes copper equivalent1 (“CuEq”).

• Multi-generational asset: Initial +70-year life of mine ("LOM") , producing approximately 22.3 million

tonnes (“Mt”) of copper, 37.2 Moz of gold and 763 Moz of silver.

1 Copper equivalent (CuEq) based on production after recoveries and metal prices of $4.60/lb Cu, $3,300/oz Au and $40/oz Ag. Recoveries for production are disclosed

below for reference.

• First quartile cost profile: Average cash cost 2 (net of by -product credits) per pound of copper of

negative ( $0.20/lb) and an all-in sustaining cost 2 (“AISC”) per pound of copper of $ 0.47/lb (net of by-

product credits) over the first 25 full years of operation.

• Staged development: Enables Vicuña to incorporate ongoing optimization for the later phases of the

Project, manage development risk and fund future development through operating cash flow.

• Significant free cash flow: Average annual free cash flow 2 of $2.2 billion per year (after expansionary

capital) during the first 25 full years of operation.

• Leveraged to copper and gold: LOM revenue contribution of approximately 60% copper, 32% gold and

8% silver.

• Capital intensity below $30,000/tonne CuEq: Stage 1 capital of $7.1 billion with an after-tax payback

period of 8.4 years3 and an after-tax internal rate of return ("IRR") of 14.8% which includes all the stages.

• Resource growth: The updated Mineral Resource grew significantly compared to the previous estimate4

o Contained copper of 14 Mt Measured and Indicated (“M&I”) and 32 Mt Inferred. An increase of

12% in contained M&I and 28% Inferred copper.

o Contained gold of 36 Moz M&I and 61 Moz Inferred. An increase of 12% contained M&I gold and

26% Inferred gold.

o Contained silver of 729 Moz M&I and 1,051 Moz Inferred. An increase of 11% M&I silver and 30%

Inferred silver.

• Base-case scenario that establishes a world-class project: Net present value ("NPV8%") of $9.5 billion

after-tax at $4.60/lb copper, $3,300/oz gold and $40/oz silver.

o Stage 1 is clearly defined providing a blueprint for initial development, ongoing studies on

Stages 2 and 3 are expected to deliver further optimization.

• At spot copper, gold and silver prices ($6.00/lb copper, $5,000/oz gold and $80/oz silver), the NPV 8%

increases to $28.8 billion and the IRR to 25.5% with a payback of 5.4 years.

The Study marks a significant milestone for the Company and our partner BHP, positioning us to make a potential

sanctioning decision as early as year-end. Next steps include detailed design and engineering for Stage 1, ramp

up of project readiness activities and upgrades to the access road, all of which will advance the Project toward

long-life, high-quality copper production while unlocking value across the broader district.

The Preliminary Economic Assessment was prepared in accordance with National Instrument 43-101 ("NI 43-

101") standards on a 100% basis. The base case was completed at a copper price of $4.60/lb, a gold price of

$3,300/oz and a silver price of $40/oz.

2 Cash Cost (net of by -product credits),all-in sustaining cost and free cash flow are Non-GAAP measures, please see the section "Cautionary Note Regarding Non -GAAP

Measures" below. The Vicuña Project does not currently have operations and therefore does not have historical equivalent measures to compare to. As such, the Company

cannot perform a reconciliation of these Non-GAAP measures.

3 Initial capital from the start of 2027 and payback period from the start of 2030.

4 See news release dated May 4, 2025 and previous technical report entitled “NI 43 -101 Technical Report on the Vicuña Project, Argentina and Chile”, with an effective

date of April 15, 2025 for information with respect to the previous Mineral Resource estimate . The Project is a 50:50 joint venture between Lundin Mining and BHP

Canada. Lundin Mining’s attributable interest in the Mineral Resource estimate is 50%.

The PEA is preliminary in nature, it includes Inferred Mineral Resources that are considered too speculative

geologically to have the economic considerations applied to them that would enable them to be categorized as

Mineral Reserves, and there is no cert ainty that the Preliminary Economic Assessment will be realized. Mineral

Resources that are not Mineral Reserves do not have demonstrated economic viability.

Vicuña Study Details

Vicuña engaged a consortium of independent consultants, led by Fluor Corporation, a leading global engineering,

procurement and construction management (EPCM) firm. Fluor provides professional and technical solutions

across energy, chemicals, mining, infrastructure, and government sectors. The Study was supported by additional

leading consultants with expertise in various fields, including Ausenco Pty Ltd, Inti Mining Smart Solutions., Knight

Piesold Ltd., and SLR Consulting (Canada) Ltd.

The Study envisions a conventional open pit mining and milling operation with a nominal initial nameplate

processing capacity of 175,000 tonnes per day (“tpd”) (approximately 64.0 million tonnes per annum “Mtpa”), with

an anticipated expansion to 293,000 tpd (approximately 107.0 Mtpa). The Study evaluates the recovery of copper,

gold, and silver through a conventional process plant that includes crushing, grinding, and flotation to produce a

copper concentrate . In the initial years , the concentrator will be fed with mineralization from the Josemaria

deposit and then transition over to mineralization from the Filo del Sol deposit providing higher grades. Oxide

material overlaying the Filo del Sol deposit is treated separately via a two-stage heap leach process designed to

recover copper-rich, copper–gold, and gold-rich minerals. The heap leach circuit will produce high-purity copper

cathode and gold doré product.

Deposit Geology and Mineral Resource

The Vicuña Project area of the central Andes encompasses the crest of the ridge along the Chile-Argentina border

and the area eastward into Argentina between the Maricunga belt to the north and the El Indio belt to the south.

5 Economic sensitivities use a silver price of $40/oz.

Regional mineralization in the area is typically related to porphyry and epithermal systems developed during the

Late Oligocene to Miocene compressive stages of Andean arc development. The two major deposits thus far

discovered on the Vicuña Project are the porphyry-epithermal systems of Filo del Sol and Josemaria.

The Filo del Sol alignment is an approximately 8 kilometre (“km”) long, north to northeast trending series of

prospects of mid-Miocene porphyry copper-gold and related epithermal mineralization. The Filo del Sol deposit

lies along the alignment as an elongate 5.4 km long domain of contiguous mineralization across three zones: An

older, more deeply eroded porphyry copper–gold mineralized domain in the Tamberías area; a slightly younger,

partly blind to the surface porphyry copper–gold mineralized intrusions in the Aurora zone in the central domain;

and deeper mineralization along a northeast trend in the Bonita area in the north. The domains together

represent the mineralization around a large hydrothermal breccia centre cored by porphyry intrusions.

The Josemaria deposit area is characterized by a Late Oligocene porphyry copper-gold system, emplaced along a

north-trending structural corridor, to the east of Filo del Sol. The system includes disseminated porphyry style

mineralization that also saw extreme telescoping and overprinting of the porphyry domain by advanced argillic

alteration and related high -sulphidation mineralization. The reconstituted copper mineralization was upgraded

in these tele scoped domains, which were then additionally enriched through supergene processes when the

high-grade part of the system was exposed to surface in modern times.

Vicuña Mineral Resource Highlights

• One of the world’s largest copper, gold, and silver resources6

o Contained copper of 14 Mt M&I and 32 Mt Inferred.

o Contained gold of 36 Moz M&I and 61 Moz Inferred.

Mineral Resource Expansion

The updated Mineral Resource estimate for the Vicuña Project, effective October 31, 2025, reflects meaningful

growth in the resource base, primarily at the Filo del Sol deposit. Changes relative to the previous estimate are

driven mainly by new drilling at Filo del Sol, which supported both resource expansion and conversion to higher

confidence categories, together with updated metal price assumptions and cut-off criteria applied in the PEA.

No new drilling was incorporated at Josemaría. Changes to the Josemaría Mineral Resource are attributable to

updated metal prices and cut-off assumptions.

An ongoing drill program at Filo del Sol is focused on continued resource conversion, key mine-site condemnation

drilling, and the collection of geotechnical and geometallurgical data to support ongoing technical studies.

Mining

Mining is to be carried out using conventional open pit techniques. The two deposits (Filo del Sol and Josemaria)

will share a common fleet of 360 tonne haul trucks, electric rope shovels, hydraulic shovels, and large loaders.

The mine design for both pits is based on 15 m benches (often double benching), with slope angles ranging from

33 to 45 degrees. Mining is planned to be done in several phases within the two deposits. In the conceptual mine

plan, Josemaria is mined for the first 6 years targeting higher grade material to the mill during the earlier years

and/or delaying waste stripping until later years. Mill feed grade averages 0. 40% copper, 0.31 g/t gold and 1.41

g/t silver over the first 6 years (Josemaria deposit).

The initial mine life is 70 years with upside potential through regional exploration and identification of

materialization along strike and to the east and west edges of the pit. The Company believes there are additional

opportunities to further extend mine life by exploration.

Mine planning and scheduling were engineered to feed up to 64.0 Mt per year of Josemaria mineralization to the

process plant . Upon commissioning of the Filo del Sol’s district leaching facilities, mini ng at Filo del Sol will

commence, increasing the total mine movement at the Project to 300 Mt of material mined per year. Once Filo

del Sol sulphide mineralization becomes higher grade than Josemaria, Josemaria mineralization will be deferred

to the end of the mine life.

The Study outlines an average production profile of 400,000 tonnes of copper, 700,000 ounces of gold and 22

Moz of silver over a 25-year period with annual peak production estimates of 580,000 tonnes of copper per year,

1.1 Moz of gold per year and 56 Moz of silver per year.
