Lundin Mining Reports Second Quarter 2025 Results

Vancouver, August 6, 2025 (TSX: LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation (“Lundin Mining” or the

“Company”) today reported its second quarter 2025 financial results. Unless otherwise stated, results are presented in

United States dollars on a 100% basis.

Jack Lundin, President and CEO commented, “Our portfolio of high -quality assets continued to generate solid results

during the quarter keeping us firmly on track to achieve the midpoint of our production guidance. This resulted in over

$930 million in revenue and $211 million in free cash flow from operations1. Consolidated copper cash costs decreased to

$1.92/lb, down 7% from last quarter. Importantly, our record safety performance in Q1 continued into Q2, with the

Company achieving the lowest Total Recordable Injury Frequency Rate recorded in the past ten years.

"With the successful $1.4 billion sale of our European assets, we paid down our term loan and reduced net debt excluding

lease liabilities 1 to $135 million as at the end of Q2. At our Capital Markets Day ("CMD") event in June, we showcased

medium-term brownfield expansion opportunities that complement the long -term growth potential of the Vicuña Project.

The Vicuña Project team continues to progress with parallel studies supporting a multi -phased development plan and an

integrated technical report remains on track for Q1 2026. Our five -year financial outlook provided at the CMD event

demonstrates our ability to fund these transformational growth initiatives while maintaining shareholder returns in the

form of share buybacks and dividends. We look forward to continuing to build off the solid first half performance for the

remainder of 2025.”

Second Quarter Operational and Financial Highlights

Strong operational results drove earnings in the second quarter supported by continued higher gold prices. The

Company's balance sheet was also strengthened from the sale of its European assets. 2025 production guidance was

reaffirmed in the quarter and cash cost guidance was improved.

• Copper Production: Production of 80,073 tonnes of copper in the second quarter from continuing operations.

• Other Production: During the quarter, 38,118 ounces of gold and 2,713 tonnes of nickel were produced.

• Revenue: $937.2 million in the second quarter from continuing operations with a realized copper price 1 of $4.40 /lb

and a realized gold price1 of $3,478 /oz.

• Net Earnings and Adjusted Earnings 1: During the quarter, net earnings from continuing operations attributable to

shareholders of the Company was $126.1 million ($0.15 per share) and adjusted earnings from continuing operations

was $98.2 million ($0.11 per share).

• Adjusted EBITDA1: $394.7 million was generated from continuing operations for the quarter.

• Cash Generation: Cash provided by continuing operations was $314.6 million and free cash flow from operations 1

was $211.1 million, which was impacted by significant cash income taxes paid at Candelaria in the quarter due to

timing of payments and increased taxable income.

• Growth: During the quarter the Company outlined strategic aspirations to become a global top-ten copper producer

and achieve copper production of over 500,000 tonnes per year and gold production of over 550,000 ounces per

year:

◦ On April 16, 2025 Lundin Mining completed the sale of Neves -Corvo and Zinkgruvan to Boliden AB

("Boliden") for cash proceeds of $1,314.6 million, net of cash disposed and transaction costs, and

subsequently repaid in full its term loan of $1,150 million and repaid $170.0 million of amounts drawn on its

revolving credit facility.

◦ During the quarter the Company announced a Mineral Resource estimate (the "Vicuña Mineral Resource")

for the Vicuña Project which highlighted one of the world’s largest copper, gold and silver Mineral Resources,

with the potential to support a globally ranked mining complex. The Company continues to advance the

integrated study of the Filo del Sol and Josemaria deposits, which is expected to be completed in Q1 2026.

non-GAAP and other performance measures in its Management's Discussion and Analysis ("MD&A") for the three and six months ended June 30, 2025 and

the Reconciliation of Non-GAAP Measures section at the end of this news release.

▪ Contained copper of 13 million tonnes (“Mt”) Measured and Indicated at 0.35% copper (“M&I”) and

25 Mt Inferred at 0.32% copper.

▪ Contained gold of 32 million ounces (“Moz”) M&I at 0.27 g/t gold and 49 Moz Inferred at 0.19 g/t

gold.

▪ Contained silver of 659 Moz M&I at 5.6 g/t silver and 808 Moz Inferred at 3.2 g/t silver.

◦ On June 18, 2025, the Company hosted a Capital Markets Day, which outlined medium -term, low -cost

brownfield expansion opportunities alongside the Vicuña Project which offers transformational long -term

growth potential. The Company also provided guidance on financial performance for the next five years that

outlined its ability to fund future growth plans.

• 2024 Sustainability Report Published: The Company continues to demonstrate its commitment to sustainability as

an integral part of the Company's overall strategy for disciplined growth and released its annual 2024 Sustainability

report on May 26, 2025.

• Shareholder Returns: A quarterly dividend of $0.0275 per share has been declared. In addition, the Company

purchased 4,629,000 common shares during the quarter at an average share price of C$10.91 for total consideration

of $36.2 million under its normal course issuer bid. So far during 2025, Lundin Mining has cancelled 13,058,800

common shares at a cost of approximately $104.0 million.

• Outlook: The Company reaffirms it is tracking to full year guidance for production of all metals, including 303,000 –

330,000 tonnes of copper. The Company has further revised cash cost guidance at Chapada which supports its

previously lowered overall consolidated cash cost guidance for the Company to $1.95 to $2.15 per pound cash cost.

Annual sustaining capital expenditure guidance has remained unchanged with reductions at Caserones being offset

by higher capital expenditure at Chapada. Expansionary capital guidan ce has increased, driven by an increase in the

Vicuña Project budget.

• Discontinued Operations: On April 16, 2025, the Company completed the sale of its European assets, Neves -Corvo

and Zinkgruvan, to Boliden. The operating results of the Neves -Corvo and Zinkgruvan reporting segments have been

classified as net earnings from discontinued operations. Net earnings from discontinued operations for the quarter

of $102.4 million includes a gain on disposal of $106.4 million, net of income tax.

c Discontinued operations are to April 16, 2025.

• For the quarter ended June 30, 2025, the Company generated revenue from continuing operations of $937.2 million

(Q2 2024 - $878.3 million).

• Gross profit from continuing operations for the quarter of $271.3 million was $42.8 million higher than in the prior

year comparable period of $228.5 million. The increase was primarily due to higher sales volume, lower treatment

charges, and cost savings from operational efficiencies.

• Net earnings from continuing operations for the quarter of $159.6 million was higher than in the prior year

comparable period of $119.4 million. The increase was primarily due to an increase in gross profit combined with

lower interest expense due to the repayment of debt in the quarter with cash proceeds received from the sale of

the Neves-Corvo and Zinkgruvan operations.

• Adjusted earnings 2 from continuing operations for the quarter of $98.2 million, increased from $83.4 million

primarily as a result of higher gross profit.

• Cash provided by operating activities related to continuing operations for the quarter of $314.6 million represented

a decrease of $125.4 million from the prior year comparable period of $440.0 million. The decrease was primarily

due to significant cash income taxes paid in the quarter of $168.0 million (Q2 2024 - $47.1 million ), primarily at

Candelaria, and a reduction in working capital inflows of $111.4 million to $37.4 million from $148.8 million in the

prior year comparable period.

• In the quarter, sustaining capital expenditures 3 from continuing operations of $115.9 million were lower than in the

prior year comparable period of $126.6 million . The reduction was primarily due to lower spending at Candelaria

from reduced deferred stripping.

• Expansionary capital expenditures 2 of $33.7 million in the quarter were lower than $87.1 million in the prior year

comparable period due to the formation of Vicuña, a 50/50 joint arrangement with BHP Investments Canada Inc.

("BHP") (the "Joint Arrangement"), on January 15, 2025. From this date, the Company's expansionary capital

expenditures include 50% of Vicuña's capital expenditures.

• Free cash flow 2 from continuing operations for the quarter of $165.0 million was lower than in the prior year

comparable period of $226.3 million primarily due to reduced cash provided by operating activities related to

continuing operations, partially offset by lower sustaining and expansionary capital expenditures.

• As at August 6, 2025, the Company had cash of approximately $276 million and net debt excluding lease liabilities 2

of approximately $139 million.

Candelaria (80% owned): Candelaria produced 36,999 tonnes of copper and 20,574 ounces of gold in concentrate on a

100% basis during the quarter. Production in the quarter and year -to-date periods were positively impacted by increased

throughput as a result of softer ore feed and higher ball mill runtime due to rescheduled maintenance in the quarter.

Mining and processing in the quarter was focused on Phase 11 with some contribution from higher grade areas of Phase

12. Cash cost 4 of $1.81/lb during the quarter was positively impacted by higher production and favourable foreign

exchange.

Caserones (70% owned): Caserones produced 29,290 tonnes of copper and 380 tonnes of molybdenum on a 100% basis

during the quarter. Production in the quarter was impacted by lower grades as a result of mine sequencing with mining

focused on Phases 6 and 7 as mining of Phase 5 nears completion. Throughput was impacted slightly by a temporary

reduction in primary crusher availability during the quarter and copper cathode production benefitted from increased

material placed on the leach pad. Cash cost of $2.45 /lb in the quarter benefitted from lower mining and milling costs, as

well as lower treatment and refining charges and favorable foreign exchange.

Chapada (100% owned): Chapada produced 11,274 tonnes of copper and 17,544 ounces of gold in concentrate during the

quarter. Ore from the North and South open pits was mined and processed, resulting in higher grades as compared to the

prior quarter which focused on processing ore from the older low -grade stockpile. Cash cost of $0.75 /lb was the lowest

amount since 2021, and benefitted from higher gold by-product credits as a result of higher realized gold prices, combined

with favourable foreign exchange and higher copper sales volume.

Eagle (100% owned): Eagle produced 2,713 tonnes of nickel and 2,510 tonnes of copper in the quarter. Production was

impacted by a temporary reduction in equipment availability and reduced throughput as a result of an unplanned four -

day power outage. Production gradually increased to normal levels following the completion of ramp rehabilitation at

Eagle East in the previous quarter. Nickel cash cost of $2.02/lb was positively impacted by higher by -product credits and

higher nickel sales volumes.

Outlook

The Company remains on track to meet annual production guidance for all metals. In light of higher gold prices, the cash

cost guidance range for Chapada is further reduced from that announced on June 17, 2025.

At Candelaria, production in the second half of the year is expected to be in line with the first half of the year to meet th e

Company's annual production guidance for 2025. Cash costs at Candelaria are tracking to the mid -point of guidance for

the full year.

At Caserones, higher copper head grades anticipated in the second half of the year, together with strong cathode

production are expected to sustain the Company's annual production guidance for 2025.

At Chapada, production is expected to be weighted to the second half of the year as copper grades and recoveries in the

second half of the year are expected to remain in line with the second quarter. Mine sequencing is expected to result in

processing increased fresh ore from the North and South pits and less lower -grade stockpile material. Cash costs are

expected to continue to benefit from higher gold prices, leading to a further reduction in annual guidance as compared to

that previously announced by the Company (see News Release dated June 17, 2025).

At Eagle, grades and mining rates are expected to normalize in the second half of the year, supporting annual production

guidance. Mining at the Eagle deposit is expected to be completed towards the end of the year and higher grade ore from

Eagle East will be sourced.

2025 Exploration Investment Guidance

Total exploration expenditure guidance for 2025 remains at $40 million, which has potential to increase subject to

successful exploration results at the Boulderdash property. Drilling metres ("m") across the Company have been re -

allocated to account for the anticipated earn-in agreement with Talon Metal Corp. ("Talon") and the Boulderdash property.

Exploration

During the quarter, exploration activity focused on in -mine and near -mine targets at the Company's operations.

Exploration drilling at Candelaria was focused on Candelaria South (Mariana) and Candelaria Norte with a total of 1,533m

completed during the quarter.

At Caserones, drilling started for the year early in the quarter with one rig at the Caserones pit targeting deep high -grade

copper breccias and two rigs at Angelica targeting copper sulphides beneath the Angelica oxide deposit, totaling 3,097m.

A total of 5,077m was drilled using two rigs at Chapada. One rig was in the Saúva resource area, focusing on adding high

grade resources. A second rig was testing shallow targets outside the Saúva resource area and near-mine targets.

At Eagle, drilling commenced at the Boulderdash property with two rigs targeting potential extensions of the known nickel-

copper mineralized intrusion. This drilling is part of an exclusivity agreement with Talon to negotiate an earn -in agreement

for the right to acquire up to a 70% ownership interest in the Boulderdash property that is near the Company's Eagle

mine. Total drilling for the quarter was 1,874m, as part of the proposed 10,000m Phase 1 earn-in drilling program.

Vicuña

On January 15, 2025, the Company completed the joint acquisition of all of the issued and outstanding common shares of

Filo Corp. not already owned by Lundin Mining and concurrently formed the Joint Arrangement, resulting in the Company

indirectly holding a 50% interest in Vicuña Corp., an independently managed joint operation which owns the Josemaria

project in Argentina and the Filo del Sol project in Argentina and Chile. BHP indirectly owns the remaining 50% interest in

Vicuña.

In 2025, work continues to focus on advancing studies related to the synergies between the Filo del Sol and Josemaria

projects, continuing the drilling program, and progressing the development of the Josemaria project.

Activities at Josemaria during the quarter focused on the completion and submission of the Environmental Impact

Assessment ("EIA"), power infrastructure planning, and continued advancement of the water program. Mobilization and

preparatory works for the northern access road commenced in the quarter with full construction scheduled to begin later

in 2025 following the winter season. Work also continued on a multi -phased development concept pertaining to the

Josemaria and Filo del Sol deposits. An integrated technical report is targeted to be complete by early 2026.

Government relations activities continued with both the national and provincial governments. In conjunction, discussions

on provincial agreements continued to be advanced. Work also progressed in the quarter on an application for the

Argentinean Basis Law - Incentive Regime for Large Investments ("RIGI").

Community investment programs were launched in 2025 with a focus on gender, youth training, cooperative

development, and rural livelihoods.

On May 4, 2025, the Company announced an initial Mineral Resource estimate for the Filo del Sol sulphide deposit, an

update to the Mineral Resource estimate for the Filo del Sol oxide deposit and an update to the Mineral Resource estimate

for the Josemaria deposit, which highlighted the combined Vicuña Project as one of the largest copper, gold and silver

resources in the world. Details of the Vicuña Mineral Resource are set out in the "NI 43-101 Technical Report on the Vicuña

Project, Argentina and Chile" with an effective date of April 15, 2025 (the "Vicuña Technical Report").

The Filo del Sol and Josemaria deposits have significant high -grade mineralization that could provide the initial years of

mining for the Project.

• Filo del Sol high -grade core at cut -off of 0.75% copper equivalent ("CuEq"): 606 million Mt (M&I) at 1.14% CuEq 5

(0.74% Cu) for contained metal of 4.5 Mt copper at 0.74%, 9.6 Moz gold at 0.49 g/t and 259 Moz silver at 13.3 g/t.

• Near surface Josemaria high -grade core at cut -off of 0.60% CuEq: 196 Mt (M&I) at 0.73% CuEq 6 (0.50% Cu) for

contained metal of 978 kt copper at 0.50%, 2.4 Moz gold at 0.38 g/t and 11 Moz silver at 1.7 g/t.

The Filo del Sol deposit also contains copper oxide mineralization at surface.

• Lower capital intensity heap leach oxide cap of 434 Mt (M&I) at 0.34% copper (1.5 Mt), 0.28 g/t gold (3.9 Moz) and

2.5 g/t silver (35 Moz)

• High-grade oxides at a cut-off of 0.60% CuEq of 181 Mt (M&I) at 1.05% CuEq7(0.50% Cu) for contained metal of 911

kt copper at 0.50%, 2.3 Moz gold at 0.39 g/t and 230 Moz silver at 39.6 g/t.

There is clear potential for expansion. Drilling at Filo del Sol bottomed in mineralization and is open at depth, while drill ing

at the Flamenco zone approximately 2 kilometers to the south has intercepted mineralization beyond the limits of the

current resource pit shell.

During the quarter, the Company spent $32.2 million in capital expenditures compared to $87.1 million in the prior year

comparable period. On a year-to-date basis, the Company spent $74.9 million compared to $143.1 million in the prior year

comparable period. Reduced spending in both the quarter and year -to-date periods is due to the formation of Vicuña on

January 15, 2025. From this date, the Company's expansionary capital expenditures include 50% of Vicuña's capital

expenditures.

Expansionary Projects

The Company has a number of brownfield expansionary projects that are expected to contribute to medium -term growth

in its existing operating asset portfolio. Combined, these opportunities could add 30,000 to 40,000 tonnes of copper

production growth and 60,000 to 70,000 ounces of annual gold production through low capital intensity growth projects.

Candelaria

Projects are ongoing to support the mine life extension under the Environmental Impact Assessment ("2040 EIA"). During

the quarter, $1.5 million was spent on relocation of electrical transmission lines to allow for expansion of the open pit.

During the year-to-date period, $21.7 million of spending also included key equipment deliveries as well as the acquisition

of mining rights.

Additionally, the Company is working on an expansion opportunity which re -envisions the previously disclosed Candelaria

Underground Expansion Project ("CUGEP") to a lower -capital intensive option with only marginally lower production rates.

The Company forecasts that this could increase underground throughput capacity by approximately 50% to 60% to

~22,000 tonnes per day from current levels of 12,000 to 14,000 tonnes per day and increase annual copper production by

approximately 10% or 14,000 tonnes of copper per year. The opportunity includes insourcing of the Company's

underground mining contract, which is anticipated to provide incremental copper production gains from higher

productivity rates through improved mechanical availability and higher development rates. Initial recruitment has begun

as part of the internalization process, along with training and licensing of blast technicians. It is expected that by mid-2026,

the initial underground mining crews will have been internalized.

Caserones

While cathode production at Caserones has remained strong over recent quarters, the Company is anticipating that

through continued improvements with its leaching practices and additional oxide material, incremental future production

can be realized in the range of 7,000 to 10,000 tonnes of copper per year.

Chapada

The development of the Saúva deposit, approximately 15 kilometers from the Chapada mine, represents a near mine

opportunity to add approximately 15,000 to 20,000 tonnes of copper production per year and 50,000 to 60,000 ounces of

gold production per year, representing 50% and 100% production increases respectively. This is expected to be achieved

through the installation of additional grinding capacity and by offsetting lower grade material with higher grade ore from
