Lundin Gold Reports Fourth Quarter and Full Year 2025 Results

Record cash flow generation and expanding growth pipeline across epithermal and

porphyry systems

Lundin Gold Inc. (TSX: LUG; Nasdaq Stockholm: LUG; OTCQX: LUGDF) (“Lundin Gold” or the “Company”) today

announced its financial results for the fourth quarter and year ended December 31, 2025. The year delivered

exceptional operational and financial performance, including gold production of 498,315 oz, in line with elevated

guidance, and record free cash flow¹ of $926 million. The Company generated record revenues of $1.78 billion

from sales of 503,330 oz at an average realized gold price 1 of $3,594 per oz, supported by stable operations ,

strong margins, and completion of the process plant expansion early in the year.

The Company’s gold mine in Ecuador, Fruta del Norte (“FDN”) , achieved average throughput of 5,009 tpd with

recoveries of 89.0%. Cash operating costs¹ of $838/oz and AISC¹ of $1,015/oz remained competitive despite

higher royalties and employee profit sharing tied to strong gold prices , resulting in robust margins throughout

the year.

The Company also advanced its most extensive exploration program to date, drilling 121,519 metres across

conversion and near mine programs and further demonstrating the significant potential of the broader land

package. Lundin Gold returned a record $664 million in dividends during the year and has declared $ 1.15 per

share payable in Q1 2026. All amounts are in U.S. dollars unless otherwise indicated.

Jamie Beck, President and CEO, commented “2025 was an outstanding year for Lundin Gold, marked by strong

operational delivery, record financial results and dividends to our shareholders. FDN again demonstrated strong

production and exceptional cash flow, reinforcing the strength of this world-class asset.

Our exploration results were equally impressive. Following our MRMR update, FDNS now carries an initial

Mineral Reserve and FDN East has an initial Inferred Mineral Resource. Drilling at both targets continues to

demonstrate the scale and continuity of these high -grade epithermal systems, with the potential to extend the

life of mine.

The emerging copper gold porphyry systems at Sandia, Trancaloma, Castillo and other targets further illustrate

the exceptional endowment of the district. Together with the growth at FDNS, FDN East and Bonza Sur, the

combination of multiple high grade epithermal deposits and several promising porphyry centres provides rare

long term optionality and a powerful foundation for future district scale growth

With no debt, a strong balance sheet, and a growing pipeline of high -quality opportunities, we enter 2026 with

considerable strategic flexibility and remain focused on disciplined execution and responsible growth.”

FOURTH QUARTER AND FULL YEAR HIGHLIGHTS

Year ended December 31, 2025

• FDN achieved annual gold production of 498,315 oz, comprised of 324,485 oz in concentrate and

173,830 oz as doré, which meets the Company’s 2025 elevated guidance.

• A total of 1,832,695 and 1,828,225 tonnes of ore was mined and processed, respectively. In 2025,

average mill throughput exceeded 5,000 tpd, demonstrating the benefits of the process plant

expansion project completed in Q1 2025. The mine also ramped up progressively throughout the

year keeping pace with the mill.

• The average grade of ore milled was 9.5 grams per tonne (“g/t”) with improved average recoveries

of 89.0% when compared to 2024.

1 Refer to “Non-IFRS Measures” section.

• The Company sold a total of 503,330 oz of gold, consisting of 331,305 oz in concentrate and 172,025

oz as doré at an average realized gold price 1 of $3,594 per oz sold for total revenues from gold sales

of $1.81 billion. Net of treatment and refining charges, revenues for 2025 were $1.78 billion.

• Average realized gold price1 was positively impacted by rising gold prices on provisionally priced gold

sales, which include $3,426 per oz of gross price received and a favourable impact of $168 per ounce

from adjustments to provisionally priced sales.

• Cash operating costs 1 and AISC 1 for 2025 were $838 and $1,015 per oz of gold sold, respectively.

These figures reflect the impact of higher accrued royalties and statutory profit sharing payable to

employees which were driven by record -high average realized gold prices 1. AISC 1 also includes

sustaining capital costs related to the expansion of the tailings storage facility.

• The Company generated record cash from operating activities of $1.02 billion and free cash flow 1 of

$926 million or $3.84 per share. The strong free cash flow enabled the Company to return $664

million to shareholders through dividends and resulted in a cash balance of $630 million at December

31, 2025.

• Earnings before interest, taxes, depreciation, and amortization 1 (“EBITDA”) were $1.24 billion while

income from mining operations was $1.23 billion which, after deducting corporate, exploration, and

taxes, resulted in net income of $792 million for the quarter or $3.29 per share.

Fourth Quarter of 2025

• Focus on Operational Excellence programs led to the highest quarterly mine production since the

beginning of operations with 501,301 tonnes of ore mined.

• The mill processed 484,950 tonnes of ore at an average throughput of 5,271 tpd despite lower mill

operating hours due to unplanned maintenance activities at the mill. This was also a quarterly record

since the beginning of operations. The average grade o f ore milled was 8.7 g/t with average

recoveries of 88.3%.

• Gold production was 119,483 oz which was comprised of 78,577 oz in concentrate and 40,906 oz as

doré.

• Gold sales totaled 124,041 oz, consisting of 81,348 oz in concentrate and 42,693 oz as doré, resulting

in gross revenues of $533 million at an average realized gold price1 of $4,299 per oz. Net of treatment

and refining charges, revenues for the quarter were $527 million.

• Average realized gold price 1 includes $4,133 per oz of gross price received and a favourable impact

of $166 per ounce from adjustments to provisionally priced sales.

• Cash operating costs1 and AISC1 were $947 and $1,193 per oz of gold sold, respectively. The increase

in both metrics compared to previous quarters is due to the impact of higher accrued royalties and

statutory profit sharing payable to employees which were driven by record-high average realized gold

prices1. Furthermore, AISC1 was impacted by the timing of sustaining capital expenditures incurred.

• The Company generated cash from operating activities of $358 million and free cash flow 1 of $328

million, or $1.36 per share.

1 Refer to “Non-IFRS Measures” section.

4

• EBITDA1 was $364 million while income from mining operations was $373 million which, after

deducting corporate, exploration, and taxes, resulted in net income of $234 million for the quarter

or $0.97 per share.

Outlook

• Gold production at FDN for 2026 is estimated to be between 475,000 to 525,000 oz based on an

average throughput rate of 5,500 tpd. Head grade is estimated to average 8.3 g/t, with fluctuations

expected during the year as different sections of the ore body are mined. Average mill recovery for

the year is estimated at 91%.

• Cash operating costs 1 are estimated to range between $900 and $960 per oz of gold sold in 2026.

AISC1 for 2026 is expected to range between $1,110 and $1,170 per oz of gold sold and to fluctuate

quarterly based on sustaining capital activities. Unit costs are anticipated to be higher compared to

2025, primarily attributable to increased royalties and sta tutory employee profit sharing resulting

from the higher assumed gold price of $4,000 per oz. This assumption adds approximately $150 per

oz to unit costs compared to our 2025 guidance which was based on a gold price of $2,500 per oz.

• Sustaining capital expenditures1 for 2026 is projected to range between $75 million and $90 million.

This investment will fund several key initiatives that support the long -term performance of the

operation. A major component of this capital is the completion of the fifth raise of the tailings storage

facility, which began in 2025, and commencement of the sixth raise including development of a new

quarry. These raises are designed to provide additional storage capacity to accommodate higher

throughput and extended mine life. Guidance also includes expenditures for infrastructure

enhancements and mobile equipment overhauls or replacements.

• Following the recent inclusion of FDNS into Mineral Reserves, underground mine development

toward the deposit is planned to proceed. The mine to mill expansion study is examining how

incorporating FDNS into the broader mine plan could support sustaining higher processing

throughputs and contribute to increased production over time. The Company now expects to make

a single, integrated investment decision in 2026, informed by analysis of the most efficient mining

rates at both FDN and FDNS and options for increasing processing capacity beyond 5,500 tpd. The

anticipated non -sustaining capital costs associated with the initial FDNS develop ment in 2026 is

expected to be $30 - $35 million. Further details on future spending towards the integrated expansion

will be provided as this opportunity is further advanced and finalized.

• 2026 is set to be a landmark year for Lundin Gold, featuring the largest exploration program in the

Company's history with 133,000 metres of drilling planned. The near-mine exploration program will

account for approximately 100,000 metres, combining surfa ce and underground drilling aimed at

extending the mine life of FDN. This investment will target high -grade epithermal gold deposits and

advance exploration of the promising copper -gold porphyry corridor, building on the strong results

achieved to date.

• In addition to near -mine efforts, the regional program will focus on the Company’s extensive and

highly prospective land package surrounding FDN and beyond. Following reconnaissance work

completed in 2025, 8,000 metres of drilling is planned on advanced ta rgets identified within this

underexplored district, marking an important step in unlocking new growth opportunities.

• Separately, 25,000 metres of resource conversion drilling is anticipated in 2026 to support the

updating of Mineral Reserve and Resource estimates. The total investment in our 2026 exploration

program is estimated at $85 million, underscoring the Company’s commitment to growth through

exploration

• Under its dividend policy, the Company anticipates continuing to declare quarterly minimum

dividends of $0.30 per share, equivalent to approximately $300 million annually based on currently

issued and outstanding shares, plus a variable dividend equal to an amount based on at least 50% of

the Company’s normalized free cash flow, after the deduction of the fixed dividend.

The community dialogue roundtable process remained active, facilitating engagement among local

stakeholders, government representatives, and Company personnel. The Lundin Foundation's supplier

development program continued strengthening local business capacity while supporting procurement

objectives.

The partnership with Shuar Indigenous Peoples advanced through the Lundin Foundation, including the

implementation of a Shuar-owned tire distribution enterprise to supply FDN and ongoing support for cocoa

and sugar cane production projects with Shuar communities.

EXPLORATION

Near-Mine Exploration Program

During the year, the Company completed a total of 95,885 metres across 196 holes from surface and

underground, of which approximately 27,019 metres across 60 holes were drilled in the fourth quarter.

The underground near mine drilling program focused on the FDNS deposit, which remains open for expansion

in the main extensions and where one underground rig is currently turning. At FDN, one rig is currently

exploring the mineralization continuity at depth. The underground drilling program also continues to advance

at FDN East where one rig is currently exploring the central portion of the target and another rig is testing the

east extension of this vein system. Four underground rigs are active in the near mine drilling program.

The surface near mine drilling program advanced the recently discovered copper-gold mineralization at both

the Trancaloma and Sandia targets. Furthermore, surface drilling continues to explore the Castillo target, in

distinct sectors along the south extension of the Suarez Basin, and the recently discovered Chontas target.

Eleven surface rigs are drilling with four at Sandia, one at Trancaloma, one at Castillo, one at Chontas and

four targeting new discoveries.

• At Sandia, located two kilometres from FDN, drilling results confirmed and expanded the recently

discovered copper-gold mineralization. The completed drill holes helped define the western limit of

the deposit and extended a wide zone of copper-gold porphyry mineralization along the

northwestern direction both near surface and at depth.

• At Trancaloma, located four kilometres from FDN, results of the drilling program confirmed the lateral

and vertical continuity of the copper-gold porphyry mineralization. In the southeastern portion of

the target, drilling confirmed the extension of the mineralization and indicated areas for further

expansion along this direction.

• At Castillo, drilling confirmed the continuity of the high-grade copper-gold mineralization along the

southwestern direction and identified potential new areas for further drilling under the Suarez Basin

cover.

• At Chontas, located approximately ten kilometres south of FDN, the drilling program identified

another occurrence of wide, shallow, copper-gold porphyry mineralization, and indicated areas for

further expansion in this new sector.

• An exploratory drilling program is underway to define additional exploration targets underneath the

Suarez Basin cover. The program is systematically testing the presence of hydrothermal alteration

horizons and epithermal deposits pathfinder elements hosted in the Suarez Basin sediments, which

could potentially indicate gold epithermal systems at depth.

8

• The near-mine exploration program continues to advance in unexplored areas close to FDN. A

systematic exploration program employing geochemical and geophysical surveys and geological

mapping continues to cover unexplored sectors in the near mine area.

A table of fourth quarter 2025 near mine results received to date can be found in Lundin Gold’s press release

dated February 12 and 18, 2026.

Regional Exploration Program

The Company advanced its multi -year regional exploration program during 2025. The program is expected

to cover approximately 54,000 hectares on 23 of the Company’s concessions along the Zamora Copper Gold

Belt, a high potential geological setting which ho sts the Fruta del Norte mine and several large copper -gold

projects. 2026 is the first year of drill testing targets with 8,000 metres planned. The exploration program

continues to advance in the Gamora district, located 65 kilometres north of FDN and ap proximately 4

kilometres north of the Mirador copper -gold mine. Furthermore, exploration activities started at the

Guacamayo District, located 17 kilometres south of FDN.

The Gamora district comprises multiple exploration sectors that exhibit geological features similar to those

found in copper -gold porphyry systems. Additional geochemical sampling program results were received

from distinct parts of the district during th e fourth quarter and supported the identification of additional

potential targets for further evaluation. At the Guacamayo district, geological mapping followed by soil and

rock sampling was completed in the central portion of the concession. Furthermore , the recently acquired

airborne geophysics data (Radiometric and Magnetic), which covered most of the regional concessions, were

processed and supported the selection of additional potential exploration targets.

CORPORATE

• Effective November 7, 2025, Mr. Ron Hochstein stepped down as President, CEO, and Director of the

Company, and was succeeded by Mr. Jamie Beck.

• Lundin Gold completed its new five -year sustainability strategy (2026 -2030) to coincide with the

expiry of its prior five -year strategy. Anchored by the vision of “Transforming lives through

responsible mining”, the strategy is built on five strategic pill ars: Shared Prosperity, Stakeholder

Trust, Responsible Governance, Environmental Stewardship and Valued Workforce. With ambitious

targets for 2030 and beyond, this strategy will guide Lundin Gold’s legacy as a leading gold company,

a trusted community partner, and a driver of long-term local prosperity.

• The Company amended its dividend policy by increasing the existing quarterly fixed dividend from

$0.20 to $0.30 per share and introducing a new variable quarterly dividend based on at least 50% of

the Company’s normalized free cash flow during the precedin g quarter less the Fixed Dividend paid

during such period. During 2025, the Company paid out a total of $664 million in dividends as follows:

o Special dividend on June 9, 2025 for a total of $100 million;

o Quarterly fixed dividends for a total of $289 million; and

o Quarterly variable dividends for a total of $275 million.

• With the release of its 2025 year end results, the Company has declared quarterly dividends totaling

$1.15 per share, comprised of the fixed dividend of $0.30 per share and variable dividend of $0.85

per share, payable on March 2 6, 2026 (March 31, 2026 for shares trading on Nasdaq Stockholm) to
