VANCOUVER, British Columbia, Aug. 06, 2025 (GLOBE NEWSWIRE) -- Fortuna Mining Corp. (NYSE: FSM | TSX: FVI) (“Fortuna” or the “Company”) today reported its financial and operating results for the second quarter of 2025. (Results from the Company’s San Jose and Yaramoko assets have been excluded from its Q2 2025 continuing results, along with the comparative figures, due to the classification of the assets as discontinued as at June 30, 2025.)

Jorge A. Ganoza, President and CEO of Fortuna, commented, “Fortuna completed the second quarter with liquidity of more than half a billion dollars. Our strong balance sheet positions the Company to pursue growth opportunities under our control including the guided production expansion at the Séguéla Mine in 2026 and advancing to a construction decision at the Diamba Sud project in Senegal by the first half of 2026 following the completion of a PEA later this year.”

Mr. Ganoza continued, “We delivered a total of 75,950 gold equivalent ounces 1 , keeping us firmly on track to meet annual production guidance. Higher realized gold prices in the quarter contributed to a record EBITDA 1 margin of 55%. The higher consolidated AISC 1 of $1,932 per ounce of gold in the quarter was primarily driven by the timing of capital expenditures and peak mine waste stripping at Séguéla during the second quarter and into the third. These investments are critical to achieving our annual target of 160 to 180 thousand gold ounces in 2026.”

Mr. Ganoza concluded, “Looking into the second half of the year, we expect our mines to remain within annual AISC 1 guidance. At Séguéla, AISC 1 , is projected to trend higher through the year due to planned mine waste stripping to access higher-grade material, but the full-year average is expected to remain well within guidance. In contrast, Lindero’s AISC 1 , is expected to trend lower in the second half of the year as the leach pad expansion is now complete and peak stripping is behind us.”

Second Quarter 2025 Results

Q2 2025 vs Q1 2025

Cash cost per ounce and AISC Cash cost per GEO sold from continuing operations was $929 in Q2 2025, an increase compared to $866 in Q1 2025. The increase in cash costs was mostly related to lower gold equivalent ounces at Caylloma due to an increase in the gold price and the impact on the GEO calculation.

All-in sustaining costs per GEO from continuing operations was $1,932 in Q2 2025 compared to $1,752 in Q1 2025. The higher AISC is explained by the increase in cash cost as described above, higher capitalized stripping at Séguéla and timing of capital expenditure payments.

Attributable Net Income and Adjusted Net Income Attributable net income from continuing operations for the period was $42.6 million compared to $35.4 million in Q1 2025. After adjusting for impairment charges and other non-recurring items, adjusted attributable net income was $44.7 million or $0.15 per share compared to $35.7 million or $0.11 per share in Q1 2025. The increase was explained mainly by higher gold prices and higher gold sales volume. The realized gold price in Q2 2025 was $3,307 per ounce compared to $2,880 in Q1 2025. The increase in gold sales volume was due to higher gold production at Lindero. This was partially offset by the recognition of $17.5 million in withholding taxes related to the timing of local Board approvals for the repatriation of funds out of Côte d'Ivoire

Cash flow Net cash generated by operations before working capital adjustments was $96.9 million or $0.32 per share. After adjusting for changes in working capital, net cash generated by operations for the quarter was $92.7 million compared to $89.0 million in Q1 2025, as higher sales in Q2 2025 as described above were partially offset by income tax payments of $36.4 million compared to $9.4 million in Q1 2025.

Free cash flow from ongoing operations in Q2 2025 was $57.4 million, a decrease of $9.3 million over the $66.7 million reported in Q1 2025. The decrease was due to higher tax payments described above and higher sustaining capital expenditures of $7.6 million.

Q2 2025 vs Q2 2024

Cash cost per ounce and AISC Consolidated cash cost per GEO increased to $929, compared to $842 in Q2 2024. This increase was mainly driven by higher cash costs at Séguéla and lower gold equivalent ounces at Caylloma due to an increase in the gold price and the impact on gold equivalent ounces. The increase in cash cost at Séguéla was primarily due to lower head grade and higher stripping costs, consistent with the mine plan.

All-in sustaining costs per gold equivalent ounce from continuing operations increased to $1,932 in Q2 2025 from $1,641 in Q2 2024. This increase primarily resulted from the higher cash cost per ounce discussed above, increased royalties due to the higher gold price and higher sustaining capital expenditures.

Attributable Net Income and Adjusted Net Income Attributable net income from continuing operations for the period was $42.6 million or $0.14 per share, compared to $21.3 million or $0.07 per share in Q2 2024. After adjusting for impairment charges and other non-recurring items, adjusted attributable net income was $44.7 million or $0.15 per share compared to $9.3 million or $0.03 per share in Q2 2024. The increase was primarily due to higher realized gold prices, which averaged $3,307 per ounce in Q2 2025 compared to $2,334 per ounce in Q2 2024, and higher sales volumes at Séguéla (up 15%) and Lindero (up 9%), driven by increased processed ore at both mines.

Other factors influencing adjusted net income compared to Q2 2024 included the recognition of $17.5 million in withholding taxes related to the timing of local board approvals for the repatriation of funds from Côte d'Ivoire.

Depreciation and Depletion Depreciation and depletion increased by $5.4 million to $48.3 million compared to $42.9 million in the comparable period of 2024. The increase was primarily due to higher ounces sold at Séguéla. Depreciation and depletion in the period included $18.1 million related to the purchase price allocation from the Roxgold acquisition.

Cash Flow Net cash generated by operations for the quarter was $92.7 million compared to $37.4 million in Q2 2024. The increase is mainly explained by higher gold prices and higher gold volume sold at Séguéla and Lindero, and a lower negative change in working capital in Q2 2025 compared to Q2 2024.

Free cash flow from ongoing operations in Q2 2025 was $57.4 million, compared to $10.2 million reported in Q2 2024. The increase was mainly due to higher prices and metal sold as discussed above.

_ Quarterly Operating and Financial Highlights _

During the second quarter of 2025, mine production totaled 340,426 tonnes of ore, averaging 3.33 g/t Au, and containing an estimated 36,482 ounces of gold from the Antenna, Ancien, and Koula pits. Movement of waste during the quarter totaled 5,194,192 tonnes, for a strip ratio of 15.3:1. Mining continued to be focused on the Antenna, Koula, and Ancien pits.

In the second quarter of 2025, Séguéla processed 429,184 tonnes of ore, producing 38,186 ounces of gold, at an average head grade of 3.00 g/t Au, a 16% increase and a 13.5% decrease, respectively, compared to the second quarter of 2024. Higher gold production was the result of higher tonnes processed due to, in part, intermittent power outages from April to early-July 2024, which resulted in the loss of 19 days of operating time for the mill. Mill throughput during the second quarter of 2025 averaged 210 t/hr, 36% above name plate capacity.

Cash cost per gold ounce sold was $670 for the second quarter of 2025 compared to $564 for the second quarter of 2024. The increase in cash costs was a result of higher mining costs due to higher stripping requirements in line with the mine plan, and higher processing costs incurred.

All-in sustaining cash cost per gold ounce sold was $1,634 for the second quarter of 2025 compared to $1,097 in the same period of the previous year. The increase for the quarter was primarily the result of higher cash costs and higher sustaining capital from higher capitalized stripping, higher sustaining leases from an increase in the mine fleet under contract, and advancement of the stage 3 tailings lift to support higher production at Séguéla, as well as higher royalties due to higher gold prices and a 2% increase in the royalty rate effective January 10, 2025.

_ Quarterly Operating and Financial Highlights _

In the second quarter of 2025, a total of 1,828,520 tonnes of ore were placed on the heap leach pad, with an average gold grade of 0.57 g/t, containing an estimated 33,219 ounces of gold. Ore mined was 1.32 million tonnes, with a stripping ratio of 2.3:1.

Lindero’s gold production for the quarter was 23,550 ounces, comprised of 21,153 ounces in doré bars, 1,214 ounces contained in rich fine carbon, 72 ounces contained in copper precipitate, and 1,111 ounces contained in precipitated sludge. The increase in production during the second quarter of 2025 compared to the same period in 2024 was due to increase in ore placed on the pad; partially offset by lower grades.

The cash cost per ounce of gold for the quarter was $1,148 compared to $1,092 in the same period of 2024. The increase in cash costs was primarily due to higher fuel and explosive costs and additional rehandling to increase the tonnes placed on the pad.
