Jamie Beck, President and CEO commented, "2026 marks an important step forward for Lundin Gold as we continue to unlock the full potential of Fruta del Norte and its extensions. With increased throughput to 5,500 tonnes per day, sustained free cash flow generation, and the largest exploration program in our history, we are positioning the Company for long-term growth. Our investments in exploration to date are delivering tangible results, and these successes are driving future expansion opportunities, including a development decision on Fruta del Norte South ("FDNS") expected in H1 2026 and a mine to mill throughput expansion decision in H2 2026. At the same time, we remain committed to delivering strong returns to shareholders through our dividend policy. Our strategy combines operational excellence with an ambitious exploration, expansion, and development program, ensuring that Lundin Gold continues to create value well into the future."

2026 Guidance Highlights:

• Targeting between 475,000 to 525,000 ounces ("oz") of gold production.
• Maintaining competitive cost structure with cash operating costs¹ projected at $900 to $960 per oz and all-in sustaining cost ("AISC")¹ at $1,110 to $1,170 per oz of gold sold² respectively, at an assumed gold price of $4,000 an oz.
• Investing $75 to $90 million in sustaining capital¹ to support long-term operational excellence.
• Investment decision expected in H1 2026 on the development of FDNS.
• Evaluating opportunities to expand the mine and mill capacity beyond 5,500 tonnes per day ("tpd") with an investment decision expected in H2 2026.
• Launching an $85 million exploration campaign, the largest in Lundin Gold's history, with 133,000 metres of drilling planned to unlock new growth potential.
• Continuing to deliver shareholder returns through fixed quarterly dividends of $0.30 per share and a variable dividend based on at least 50% of the Company's normalized free cash flow, after deducting the fixed quarterly dividend paid.

.The Company's guidance for the year 2026 is provided in the table below:

2026 Guidance

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 costs¹ are estimated to range between $900 and $960 per oz of gold sold² in 2026. AISC¹ for 2026 is expected to range between $1,110 and $1,170 per oz of gold sold² and to fluctuate quarterly based on sustaining capital activities. Unit costs are anticipated to be higher compared to 2025 and are primarily attributable to increased royalties and statutory 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.

Gold production and sales are expected to be back-end weighted in 2026 as mill head grade is expected to improve as the year progresses due to mine sequencing. This translates to lower anticipated unit costs in the second half of the year relative to the first half.

Total sustaining capital¹ 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.

Consistent with previous years, the Company expects its free cash flow¹ during the second quarter of 2026 to be lower than other quarters due to the payment of annual statutory profit sharing to the government and employees, along with remaining income taxes owed. This variation is expected to be more pronounced in 2026 due to the Company's strong operating and financial performance achieved to date in 2025.

FDNS Development and Mine to Mill Expansion Study

With the anticipated inclusion of the FDNS deposit into the long term mine plan, a development decision is expected in the first half of 2026. Combined with strong near-mine exploration success achieved to date, the operation is positioned to potentially increase its processing capacity beyond the current 5,500 tpd. To support this opportunity, a mine to mill expansion study is underway to evaluate the technical and economic parameters of increasing throughput beyond 5,500 tpd. The results of this study will inform an investment decision, which is expected to be made in the second half of 2026.

Details on non-sustaining capital for both the potential development of FDNS and the plant expansion will be provided once these potential opportunities are further studied and finalized.

2026 Exploration Programs

Next year 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 surface 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 porphyry corridor, building on the strong results achieved to date.

In addition to near-mine efforts, the regional program will focus on Lundin Gold's extensive and highly prospective land package surrounding FDN. Following reconnaissance work completed in 2025, drilling of 8,000 metres is planned on advanced targets 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 updated Mineral Reserve and Resource estimates. The total investment in our 2026 exploration program is estimated at $85 million, underscoring Lundin Gold's commitment to growth through exploration.

2026 - 2028 Outlook

The Company's outlook for production, sustaining capital¹ and AISC¹ for the next three years is provided in the table below:

The Company's outlook reflects its current growth strategy, including the potential mine to mill expansion beyond 5,500 tpd. Production levels for 2028 may vary depending on the outcome of the expansion study and its investment decision.

Dividend

Consistent with the Company's dividend policy and subject to the approval of the Board of Directors, Lundin Gold anticipates continuing to pay a fixed quarterly dividend of $0.30 per share and a variable quarterly dividend based on at least 50% of the Company's normalized free cash flow, after deducting the fixed quarterly dividend paid during the preceding quarter.
