LUNDIN GOLD REPORTS SECOND QUARTER 2023 RESULTS AND UPDATES 2023

GUIDANCE

Fruta del Norte achieves record gold production of 269,752 oz and AISC¹ of $765 per

oz sold in the first half of 2023

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

reports results for the second quarter and first half of 2023, highlighted by Q2 production of 1 29,731 ounces

(“oz”) of gold and sale s of 128,958 oz, at a cash operating cost 1 of $644 per oz sold and all -in sustaining cost

(“AISC”)1 of $802 per oz sold. For the first half of 202 3, Lundin Gold produced 2 69,752 oz and sold 2 63,649 of

gold at an AISC of $ 765 per oz. Lundin Gold generate d $132 million in free cash flow 1 over the three -month

period, the highest quarterly free cash flow 1 achieved to date. All amounts are in U.S. dollars unless otherwise

indicated.

Based on very strong performance during the first half of 2023, the Company has increased its 2023 production

guidance to 450,000 to 485,000 oz. In addition, the Company has reduced its 2023 cash operating cost1 guidance

to $650 to $700 per oz sold and AISC 1 to $820 to $870 per oz sold. This is compared to previous produc tion

guidance of 425,000 to 475,000 oz, cash operating cost1 guidance of $700 to $760 per oz sold and AISC1 guidance

of $870 to $940 per oz sold.

Ron Hochstein, President and CEO commented, “ As a result of strong operating results in the first half of 2023

and confiden ce that our team can continue to deliver excellent performance , we are increasing production

guidance and reducing cash operating cost1 and AISC1 guidance. Specifically, we are pleased that the bottom of

our original cost guidance range is now the top of our revised cost guidance range. We’ve said that Lundin Gold

is a cash flow story for some time now, and our free cash flow generated during the second quarter highlights

that. This free cash flow enables us to fund future highly prospective exploration programs, pay down our debt,

pay dividends, and look at potential expansion opportunities. The Company is in a strong position, and I am

excited to take this momentum into the second half of the year.”

SECOND QUARTER HIGHLIGHTS

Financial Results – Highest Ever Quarterly Free Cash Flow Generation

• The Company sold a total of 128,958 oz of gold, consisting of 8 4,679 oz of concentrate and 44,279 oz of

doré at an average realized gold price 1 of $1,942 per oz for total gross revenues from gold sales of $ 250

million. Net of treatment and refining charges, revenues were $244 million.

• Cash operating costs1 and AISC1 were $644 and $802 per oz of gold sold, respectively. While cash operating

costs1 per oz sold remained consistent with the previous quarter, the ramp up of sustaining capital activities

resulted in a higher AISC1 albeit still below expected levels for the quarter.

• The Company generated cash flow of $162 million from operations and rec ord free cash flow 1 of $132

million or $0.56 per share resulting in a cash balance of $275 million at June 30, 2023.

• Earnings before interest, taxes, depreciation, and amortization 1 (“EBITDA”) and adjusted EBITDA 1 were

$149.9 million and $149.6 million, r espectively with the difference resulting from derivative gains

recognized in the quarter.

• Net income was $63.1 million including a derivative gain of $0.3 million, and net of corporate, exploration,

finance costs, and associated taxes on earnings. Adjusted earnings1, which exclude the derivative gain and

related taxes, were $59.4 million, or $0.25 per share.

Production Results – Strong Grades and Throughput Offset Weaker Recoveries

• Mine production of 404,408 tonnes of ore at an average grade of 9.0 grams per tonne.

• The mill processed 418,373 tonnes of ore at an average throughput rate of 4,598 tpd . Inclusive of the

relining of the SAG and ball mills during the first quarter, the mill has averaged a throughput rate of 4,479

tpd during the first half of 2023.

• The average grade of ore milled was 11.0 grams per tonne with average recovery at 88.0%. Recoveries were

affected by processing of ore from sectors that contain higher levels of finely disseminated sulphide

minerals which are impacting both gravity and flotation recovery.

• Gold production was 129,731 oz which was comprised of 85,395 oz in concentrate and 44,336 oz as doré.

Liquidity and Capital Resources

At the end of the second quarter of 2023, the Company is in a strong financial position.

(in thousands of U.S. dollars) As at June 30,

2023

As at December 31,

2022

Financial Position:

Cash 274,968 363,400

Working capital 268,095 194,804

Total assets 1,508,831 1,668,865

Long-term debt

Senior debt facility 91,676 172,854

Fair value of stream credit facility and offtake 304,912 287,666

Fair value of gold prepay credit facility - 207,446

Total long-term debt 396,588 667,966

The change in cash during the 2023 Period was primarily due to the full repayment of the gold prepay facility of

$208 million; principal repayments, interest and finance charges, including associated taxes, under the stream

credit facility totaling $39.0 m illion; interest and principal repayments under the senior debt of $91.1 million;

dividends of $47.4 million; and cash outflows of $20.4 million relating to sustaining capital expenditures. This is

offset by cash generated from operating activities of $307 million and proceeds from the exercise of stock

options and anti-dilution rights totaling $9.8 million.

Capital Expenditures

• Sustaining Capital:

o Construction of the fourth raise of the tailings dam advanced during the second quarter with progress

to date consistent with plan. Completion during the fourth quarter of 2023 remains as expected.

o The new warehouse was completed during the second quarter and is now operational.

4

o The underground mine maintenance facility is expected to be completed during the third quarter which

will provide additional efficiencies.

o Other sustaining capital projects such as sewage treatment plant upgrades, purchase of mobile

equipment, and other efficiency improvement projects continue to ramp up during the remainder of the

year.

o The 2023 conversion drilling program continues to advance in distinct sectors of the FDN resource.

During the quarter, the program focused on the southern extension with approximately 3,211 metres

across 20 drill holes completed. Most drill holes confirmed the continuity of mineralization in the drilled

areas. Results have pointed to a vein type mineralization in this part of the deposit, with narrower

higher-grade intervals. Some of the conversion drilling results for the southern extension remain

pending. A complete table of results received to date can be found in Lundin Gold’s press release dated

August 3, 2023.

Health and Safety

During the second quarter there were no Lost Time Incidents (“LTIs”) and no Medical Aid Incident (“MAIs”). The

Total Recordable Incident Rate across exploration and operations was 0. 00 per 200,000 hours worked for the

quarter and 0.07 for the first six months of 2023. In early July 2023, FDN operations surpassed 365 days without

an LTI or MAI with over 5.1 million hours worked.

Community

Various community projects supported by the Company continued to progress in the second quarter including

support for micro businesses established by local entrepreneurs in conjunction with the Lundin Foundation. The

local textile manufacturer, fire extinguisher maintenance company, and pest control / fumigation company

continue to work with the mine. Feasibility studies of potential new areas for local businesses continue. Efforts

have continued to ensure that local farmers retain access to local, national, and international markets.

Longstanding projects such as road maintenance, educational support to promote access to higher education,

efficiency improvements in the agricultural sector and addressing infrastructure challenges remain on track.

The Company continues to engage with local indigenous people, especially the Shuar Federation of Zamora

Chinchipe, to jointly implement projects that promote economic opportunities and the Shuar culture. In the

second quarter, the Shuar tourism company continued in its efforts to diversify its lines of business and to create

additional employment opportunities.

Corporate

The Company paid a quarterly dividend of $0.10 per share on June 27, 2023 (June 30 for shares trading on Nasdaq

Stockholm) based on a record date of June 13, 2023, for a total of $23.7 million. With the release of its second

quarter 2023 results, the Company has declared a cash dividend of $0.10 per share, which is payable on

September 26, 2023 (Sept ember 29 for shares trading on Nasdaq Stockholm) to shareholders of record on

September 11, 2023.

At the Company’s annual shareholders’ meeting on May 15, 2023, Ms. Angelina Mehta was elected as a director,

replacing Ms. Chantal Gosselin who did not stand for re-election.

5

The Company’s second TCFD-aligned climate change report and seventh annual sustainability report were

published in May. Based on publicly available data from 152 gold mines that reported their Sco pes 1 and 2

greenhouse gas emissions in 2021 and on Lundin Gold's 2022 emissions performance, the emissions intensity of

Fruta del Norte is among the lowest in the industry. The Company has set a target to be carbon neutral by 2030

with respect to its Scopes 1 and 2 emissions based on its current life of mine plan.

EXPLORATION – CONTINUING TO MAKE PROGRESS

Near-Mine Exploration Program

The near mine drilling program continues to explore extensions of major controlling structures surrounding the

FDN deposit. In the second quarter, a total of 8,609 metres across sixteen drill holes, from surface and

underground, were completed at several targets near FDN.

• The surface drilling program continues along the south extension of the East Fault, where the FDN South

(“FDNS”) and Bonza Sur targets were identified in the previous quarter. During the quarter, twelve

surface drill holes were completed and indicated continuity of mineralization at Bonza Sur and FDNS. An

exploratory hole was also completed along the north extension of the Fruta del Norte deposit. Four

surface rigs are currently drilling with two rigs at Bonza Sur, one at FDNS, and the fourth testing new

near mine sectors.

o At FDNS, six surface drill holes were completed, confirming continuity of mineralization and

defining a new geometry for the vein system in this sector. Drilling results indicate a series of

subparallel epithermal veins in a northeast ern-southwestern direction that remain open for

expansion along strike and at depth.

o At Bonza Sur, located one kilometre from FDN, five surface drill holes were completed and

continue to confirm mineralization. Drilling results recorded multiple positive intersections and

demonstrated the occurrence of three distinct mineralized zones represented by veins/veinlets

of quartz and minor chalcedony and manganoan -carbonate associated to the occurrences of

sulfides. Mineralization currently extends 500 metres along strike to the north -south and 300

metres along the downdip and remains open in all directions.

o Drilling testing new near mine sectors was recently initiated. This drilling aims to explore the

extensions of major structures at FDN with the first dr ill hole completed along the northern

extension of FDN. Results are pending.

• The underground drill program continues to explore the continuity of the FDN deposit at depth and

beyond the major faults. Four drill holes were completed and intercepted structures and hydrothermal

alteration beyond the FDN limits. In the central part of FDN, two drill holes confirmed the hydrothermal

alteration zones at depth with low -grade gold values. Two other drill holes intercepted zones of

hydrothermal alteration with vein/veinlets hosted on volcanic rocks or intrusive rocks to the east of the

FDN East Fault. Results are pending.

A complete table of results received to date can be found in Lundin Gold’s press release dated August 3, 2023.

Regional Exploration Program

The regional drilling program continues to advance in distinct sectors along the southwestern border of the

Suarez basin and a total of 2,264 metres across three drill holes were completed in the second quarter. The

program focused on the Quebrada La Negra and the newly defined Crisbel targets, where detailed geological

interpretation of exploration data and ad ditional surface works identified major structures and zones of

hydrothermal alteration.

• At Quebrada La Negra, two drill holes were completed which intercepted wide zones of hydrothermal

alteration with breccias and/or veins and disseminated sulfides. Drill results returned low values of gold

associated with epithermal pathfinder elements, such as zinc and lead, and a recent interpretation point

to new areas for further detailing farther north.

• At Crisbel, one drill hole was completed testing an unexplor ed geochemical soil anomaly (gold and

epithermal pathfinder elements such as antimony and arsenic) disposed along the contact between the

Suarez Border and the volcanic sequence. The drill hole intercepted hydrothermal alteration zones with

important quantities of sulfides hosted in brecciated volcanic rocks. Results are pending.

Newcrest Earn-In Agreement

On the concessions held by the Company’s subsidiary, SurNorte S.A., a second phase of scout drilling commenced

at the Gamora Project, located in southeast Ecuador. This work is being conducted by Newcrest Mining Limited

(“Newcrest”) as the operator under an earn -in agreement with Lundin Gold pursuant to which Newcre st can

earn up to a 50% interest in eight exploration concessions located to the north and south of Fruta del Norte. A

second phase of scout drilling was completed in the quarter at the Gamora Project, which was focused on testing

priority copper-gold targets in the Mirador copper porphyry district.

OUTLOOK – GUIDANCE INCREASED FOLLOWING STRONG FIRST HALF

Achievements during the first half of 2023 provide the Company with a positive outlook for the remainder of the

year and as a result, production guidance is increased to 450,000 to 485,000 oz while cost guidance is decreased

for both cash operating cost and AISC to $650 to $700 per oz sold and $820 to $870 per oz sold, respectively.

Production for the second half of 2023 is expected to decrease relative to the first half of the year driven by a

combination of lower grades and lower recoveries due to processing of ore from certain sectors of the mine with

less favourable geology.

In addition, AISC 1 is expected to increase with continued ramp up of susta ining capital activities and lower

expected gold production levels. Sustaining capital is expected to increase substantially during the second half

driven by construction of the fourth raise of the tailings dam as well as several other capital projects. In addition,

the conversion drilling program, aiming to convert Inferred to Indicated Mineral Resources, is planned to

continue with results expected to be incorporated into the geological model and in the new resource estimate

in the first quarter of 2024.

The near mine drilling program plans to continue to delineate the FDNS and Bonza Sur targets, where systems

of epithermal veins/veinlets have been identified and remain open. Three rigs are dedicated to the detailing and

expansion of the mineralized zones at depth and along strike. Another surface rig and underground rig continue

to explore for major discoveries in the near mine district targeting the extension of major controlling structures

at FDN in new sectors. The near mine program is expected to comprise a total of 23,000 metres of drilling for

2023.

7

The regional drilling program continues to focus on the southern Suarez Basin, advancing along the eastern and

western borders of the Basin. A second rig is expected to be added to advance numerous target areas identified

during the previous quarters. The regional drilling program continues to be expected to comprise a total of

12,500 metres for the year, with two rigs currently operating. The combined near mine and regional exploration

budget for 2023 remains at $24.6 million.

The Company anticipates declaring quarterly dividends of $0.10 per share, equivalent to approximately $100

million annually, based on currently issued and outstanding shares.
