First Quarter 2024 Results

Attributable Net Income and Adjusted Attributable Net IncomeNet income attributable to Fortuna for the quarter was $26.3 million compared to $10.9 million in Q1 2023. After adjusting for non-cash and non-recurring items, adjusted attributable net income for the quarter was $26.7 million compared to $12.2 million in Q1 2023. The increase in net income and adjusted net income is explained mainly by increased gold sales volume and higher realized gold and silver prices. Higher gold sales volume was primarily due to contributions from Séguéla which was under construction in the comparable period. This was partially offset by lower silver production at San Jose as the mine exhausts its Mineral Reserves. The realized gold and silver prices were $2,087 and $23.43 per ounce respectively compared to $1,893 and $22.52 per ounce, respectively, for the comparable period in the prior year.

Other items impacting the adjusted net income for the quarter compared to Q1 2023 were higher G&A of $2.8 million, related to the addition of Séguéla G&A and timing of execution on certain corporate G&A items; higher foreign exchange loss of $2.5 million related mainly to our West African operations; and higher interest expense of $3.6 million, explained by $2.8 million of capitalized interest expense in the comparative period vs nil in Q1 2024 and higher accretion of right of use lease liabilities.

Depreciation and DepletionDepreciation and depletion for the first quarter of 2024 was $50.3 million compared to $44.1 million in the comparable period. The increase in depreciation and depletion was primarily the result of higher sales volume and the inclusion of $15.8 million in depletion of the purchase price related to the acquisition of Roxgold Inc. This was partially offset by lower depreciation and depletion at San Jose as a result of an impairment charge in the fourth quarter of 2023.

Adjusted EBITDA and Cash FlowAdjusted EBITDA for the quarter was $95.2 million, a margin of 42% over sales, compared to $65.3 million and margin over sales of 37%, reported in the same period in 2023. The main driver for the increase in EBITDA was the contribution from Séguéla with EBITDA margin of 62% in Q1 2024, partially offset by nil EBITDA at San Jose.

Net cash generated by operations for the quarter was $48.9 million compared to $41.8 million in Q1 2023. The increase of $7.1 million reflects higher adjusted EBITDA of $29.9 million and lower taxes paid of $7.0 million as Séguéla is expected to start remittances to the government in the second quarter. This was offset by negative changes in working capital in Q1 2024 of $35.3 million compared to negative $10.8 million in Q1 2023.

The negative change in working capital of $35.3 million consisted of the following:

• An increase in receivables of $7.3 million driven by an increase in VAT receivables of $3.5 million at Séguéla and $5.8 million at Yaramoko
• An increase of inventories of $9.8 million due to a $3.2 million increase in materials and supplies and a $4.9 million increase in metals inventory
• A $17.3 million decrease in accounts payable primarily at Lindero due to $3.8 million to settle a deferred contract liability from the fourth quarter of 2023 due to timing of production, $1.8 million to settle export loans with local banks and $4.0 million related to timing of payments. Other payables movements were related to timing.

In the first quarter of 2024 capital expenditures on a cash basis were $41.4 million consisting primarily of $25.8 million in sustaining capital, including $6.7 million of brownfields exploration, and $8.8 million of non-sustaining exploration including engineering and environmental studies at Diamba Sud.

Free cash flow from ongoing operations for the quarter was $12.1 million, compared to $8.5 million in Q1 2023. The increase in free cash flow from operations was primarily the result of contributions from Séguéla which was under construction in Q1 2023 and was offset by negative working capital changes as described above.

Cash Costs and AISCCash cost per equivalent gold ounce was $879, compared to $915 in Q1 2023. The lower cash cost of sales per gold equivalent ounce was mainly due to the contribution of low-cost production from Séguéla and lower cost of sales per ounce of gold at Yaramoko related to higher grades. This was partially offset by higher cash costs per gold equivalent ounce at San Jose as previously capitalized costs are now expensed as the mine is in its last year of operations and higher cash cost per gold ounce at Lindero related mainly to lower planned head grades in 2024. Adjusting for San Jose, cash costs per gold equivalent ounces was $744 for the quarter.

All-in sustaining costs per gold equivalent ounce was $1,495 for the first quarter of 2024 compared to $1,514 for the first quarter of 2023. The decrease was primarily the result of lower cash costs being offset by higher sustaining capital expenditures primarily at Lindero due to the construction of the heap leach pad expansion, increased brownfields exploration at Séguéla to advance identified prospects and higher royalties in the period due to higher production, metal prices and a change of the royalty regime in Burkina Faso. Adjusting for San Jose, all-in sustaining costs per gold equivalent ounces was $1,412 for the current quarter.

General and Administrative ExpensesGeneral and administrative expenses for the quarter of $18.2 million were higher than the same period in 2023 as Séguéla transitioned to operations and costs are no longer being capitalized, and due to timing of corporate expenses. G&A is comprised of the following items:

Quarterly Operating and Financial Highlights

During the first quarter of 2024 total mined ore was 2.0 million tonnes at a stripping ratio of 0.54:1. A total of 1,547,323 tonnes of ore was placed on the heap leach pad at an average gold grade of 0.60 g/t, containing an estimated 29,670 ounces of gold. Gold production for Q1 2024 totaled 23,262 ounces, an 8% decrease in total ounces from the first quarter of 2023, primarily due to lower head grades. Lower mined grades are aligned with the mining sequence and the Mineral Reserves estimates.

The cash cost per ounce of gold for the quarter ending March 31, 2024, was $1,008 compared to $891, in the same period of 2023. The increase in cash cost per ounce of gold was primarily related to higher ounces sold in the comparable period due to higher production, timing of sales as 1,700 ounces of gold were still in inventory at the end of the period and additional rental equipment.

The all-in sustaining cash cost per gold ounce sold during Q1 2024 was $1,634, up from $1,424 in the first quarter of 2023. The increase in the quarter was primarily due to increased cash costs, higher capital expenditures related to the heap leach expansion and higher general and administrative costs.

As of March 31, 2024, the $51.8 million leach pad expansion project ($41.7 million capital investment in 2024) was approximately 35% complete. The construction package of the project commenced in January 2024, and is 18% complete, with contractors on site undertaking earthworks and construction of the impulsion line. The procurement and construction management (“PCM”) service was awarded to Knight Piésold consultants, with the PCM project offices installed and personnel onsite as of the third quarter of 2023. Procurement is 92% complete, with critical path items onsite. The final shipments of geomembrane and geosynthetic clay liner are currently in transit, and the pump manufacturing for the new impulsion line are all on schedule. In addition to the current works, liner installation and major mechanical works are expected to commence in the second quarter of 2024. The project is scheduled to be substantially complete in the fourth quarter of 2024, with operations beginning ore placement by the end of 2024 according to the stacking plan for the year.

In the first quarter of 2024, Yaramoko mined 123,877 tonnes of ore at an average grade of 8.30 g/t Au containing an estimated 33,053 ounces of gold. Mill production was 27,177 ounces of gold with an average gold head grade of 8.79 g/t. This represents a 3% and 48% increase when compared to the same period in 2023. A planned mill maintenance shutdown reduced mill throughput in the first quarter of 2024.

The cash cost per ounce of gold sold for the quarter ended March 31, 2024, was $752, compared to $819 in the same period in 2023. The decrease for the quarter is mainly attributed to higher head grades, which demand lower direct costs per ounce. This was partially offset by higher royalties due to higher metal prices and a change in the royalty regime in Burkina Faso which increased the royalty rate from 5% to 7% when the gold price is over $2,000 per ounce.

The all-in sustaining cash cost per gold ounce sold was $1,373 for the quarter ended March 31, 2024, compared to $1,509 in the same period of 2023. The change in the quarter was primarily due to the decreased cash cost described above, and reduced capital expenditures.

Drilling focused on infill grade control and exploring for extensions beyond the mineralized resource envelope in the deeper eastern and western portions of the 55 Zone. Stoping operations at the QVP orebody accelerated with batch mill tests confirming grade expectations.

In early April, the Government of Ghana issued a directive which stopped the export of electricity to its neighbouring countries, including Burkina Faso. As a consequence, Yaramoko has supplemented electricity used in its operations from the national grid with self-generated backup power. Production at Yaramoko has not been affected; however, Management is currently monitoring the increase in costs of the alternative energy supplies.

In the first quarter of 2024, mined material totaled 420,538 tonnes of ore, averaging 2.23 g/t Au, and containing an estimated 30,192 ounces of gold from the Antenna and Ancien pits. Movement of waste during the quarter totaled 2,538,067 tonnes, for a strip ratio of 6:1.

Production was mainly focused on the Antenna pit which produced 401,109 tonnes of ore, the remainder being mined at the Ancien pit. A total of 700,229 tonnes of waste was also mined at Ancien. Waste mining commenced at Koula during the quarter with 18,063 tonnes of waste being mined.

Séguéla processed 394,837 tonnes in the quarter, producing 34,556 ounces of gold, at an average head grade of 2.79 g/t Au.

Throughput for the quarter averaged 195 tonnes per hour (t/hr), versus name plate design capacity of 154 t/hr. Mill constraints continued to be tested with throughputs of up to 220 t/hr being recorded over a seven-day period. This was achieved with a 60/20/20 blend of fresh, transitional and oxide ore respectively. The Life of Mine (LOM) blend consists of 85% fresh rock. A relining of the mill is planned in April, and further tests will then be conducted with a blend more representative of the LOM blend. Mine design and scheduling continue with the focus being on the requirements to sustainably meet the expected higher throughput rates.

Cash cost per gold ounce sold was $459, and all-in sustaining cash cost per gold ounce sold was $948 for Q1 2024. Both were within plan and guidance.

Côte d’Ivoire has been experiencing a shortage of electricity to the national grid since mid-April, due to failures at two private power generation plants, which supply approximately 25% of the electricity to the national grid. This has led to power cuts in neighborhoods, load shedding during peak hours, and electricity rationing to industries. Power output from one of the plants (CIPREL)has now been restored; however, restoration of supply from the second plant (AZITO) is not expected until July. The Séguéla mine continues to receive energy on a daily basis from the grid with interruptions. The operation has emergency backup power generation capacity to sustain critical processes only. Management is implementing various short-and medium-term mitigating measures which include operating the mill at 25% higher throughput, adjusting mine plans to prioritize higher grade Mineral Reserves, and sourcing a power backup solution for the entire operation, expected to be available on-site in July. Production in April has been only marginally affected. Management has not modified annual guidance for the Séguéla mine at this time but continues to monitor the situation closely.

In the first quarter of 2024, San Jose produced 759,111 ounces of silver and 4,533 ounces of gold, 42% and 45% decreases respectively, at average head grades for silver and gold of 147 g/t and 0.90 g/t, 19% and 22% decreases respectively, when compared to the same period in 2023. The decrease in silver and gold production, when compared to the first quarter of 2023, is explained by lower tonnes extracted and lower grades, which is consistent with the annual plan and guidance. During the first quarter, the processing plant milled 181,103 tonnes at an average of 2,182 tonnes per day, in line with the plan for the period.

The cash cost per silver equivalent ounce for the three months ending March 31, 2024, was $21.98, an increase from $11.42 in the same period of 2023. The San Jose Mine has less operational flexibility in 2024 compared to 2023, due to the reduced and more dispersed Mineral Reserves associated with the Trinidad deposit, which also increase mine costs. Production areas contain lower head grades and a higher presence of ferrous oxides in the upper levels, which impacted recoveries by approximately 2% in the quarter. Ore processed decreased by 27% due to lower tonnes mined.

The all-in sustaining cash cost per payable silver equivalent ounce for the three months ended March 31, 2024, increased by 56% to $24.24. This compares to $15.51 per ounce for the same period in 2023. These increases were mainly driven by higher cash costs and lower production, slightly mitigated by lower capital expenditure. The operation is experiencing further cost pressures driven by the continued appreciation of the Mexican peso. The Company conducts regular assessments and trade-offs between maintaining operations and opting for a care and maintenance option.

Sustaining capital expenditure has decreased as we near the anticipated closure of the mine. Drilling in 2024 was higher due to the drilling campaign at the Yessi vein, which was discovered in the third quarter of 2023. Exploration at the Yessi vein is ongoing.

In the first quarter, the Caylloma Mine produced 315,460 ounces of silver, 11% higher compared to the first quarter 2023, at an average head grade of 87 g/t Ag.

Lead and zinc production for the quarter was 9.5 million pounds of lead, and 12.2 million pounds of zinc. Lead production was in line and zinc production decreased by 7% compared to the same period in 2023. Head grades averaged 3.48%, and 4.46%, a 7% and 14% decrease, respectively, when compared to the first quarter of 2023.

Lower metal production compared to the previous quarter was due to lower grades, which are in line with the Mineral Reserves estimates and production guidance for the year.

The cash cost per silver equivalent ounces for the three months ended March 31, 2024 was $11.61, a 12% decrease compared to the comparable period in 2023. This was primarily due to lower treatment and refining charges.

The all-in sustaining cash cost per ounce of payable silver equivalent for the three months ended March 31, 2024, increased 2% to $17.18, compared to $16.88 for the same period in 2023. The decrease in cash costs per ounce was offset by higher capital expenditure, as well as the impact of increasing silver prices on the calculation of silver equivalent ounces resulting in lower equivalent silver ounces sold.

Underground development for the quarter was mainly focused on mine levels 15, 16, 17, and 18. The increase in Brownfields expenditures is primarily attributable to greater footage, additional diamond drilling, and cost inflation.

Non-IFRS Financial Measures

The Company has disclosed certain financial measures and ratios in this news release which are not defined under the International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board, and are not disclosed in the Company's financial statements, including but not limited to: cash cost per ounce of gold sold; all-in sustaining cash cost per ounce of gold sold; all-in sustaining cash cost per ounce of gold equivalent sold; all-in cash cost per ounce of gold sold; production cash cost per ounce of gold equivalent; cash cost per payable ounce of silver equivalent sold; all-in sustaining cash cost per payable ounce of silver equivalent sold; all-in cash cost per payable ounce of silver equivalent sold; free cash flow from ongoing operations; adjusted net income; adjusted attributable net income; adjusted EBITDA and working capital.

These non-IFRS financial measures and non-IFRS ratios are widely reported in the mining industry as benchmarks for performance and are used by management to monitor and evaluate the Company's operating performance and ability to generate cash. The Company believes that, in addition to financial measures and ratios prepared in accordance with IFRS, certain investors use these non-IFRS financial measures and ratios to evaluate the Company’s performance. However, the measures do not have a standardized meaning under IFRS and may not be comparable to similar financial measures disclosed by other companies. Accordingly, non-IFRS financial measures and non-IFRS ratios should not be considered in isolation or as a substitute for measures and ratios of the Company’s performance prepared in accordance with IFRS. The Company has calculated these measures consistently for all periods presented.

To facilitate a better understanding of these measures and ratios as calculated by the Company, descriptions are provided below. In addition see “Non-IFRS Financial Measures” in the Company’s management’s discussion and analysis for the three months ended March 31, 2024 (“Q1 2024 MDA”), which section is incorporated by reference in this news release, for additional information regarding each non-IFRS financial measure and non-IFRS ratio disclosed in this news release, including an explanation of their composition; an explanation of how such measures and ratios provide useful information to an investor; and the additional purposes, if any, for which management of the Company uses such measures and ratio. The Q1 2024 MD&A may be accessed on SEDAR+ at www.sedarplus.ca under the Company’s profile.

Except as otherwise described in the Q1 2024 MD&A, the Company has calculated these measures consistently for all periods presented.

Reconciliation of net cash from operating activities to free cash flow from ongoing operations for the three months ended March 31, 2024 and 2023

In 2022, the Company changed the method for calculating free cash flow from ongoing operations. The calculation now uses taxes paid as opposed to the previous method which used current income taxes. While this may create larger quarter over quarter fluctuations due to the timing of income tax payments, management believes the revised method is a better representation of the free cash flow generated by the Company’s ongoing operations.

Forward-looking Statements contained herein are based on the assumptions, beliefs, expectations and opinions of management, including but not limited to the accuracy of the Company’s current mineral resource and reserve estimates; that the Company’s activities will be conducted in accordance with the Company’s public statements and stated goals; that there will be no material adverse change affecting the Company, its properties or changes to production estimates (which assume accuracy of projected ore grade, mining rates, recovery timing, and recovery rate estimates and may be impacted by unscheduled maintenance, labor and contractor availability and other operating or technical difficulties); geo-political uncertainties that may affect the Company’s production, workforce, business, operations and financial condition; the expected trends in mineral prices and currency exchange rates; that the Company will be successful in mitigating the impact of inflation on its business and operations; that the appeal filed in the Mexican Collegiate Court challenging the reinstatement of the EIA will be unsuccessful; that all required approvals and permits will be obtained for the Company’s business and operations on acceptable terms; that there will be no significant disruptions affecting the Company's operations, the ability to meet current and future obligations and such other assumptions as set out herein. Forward-looking Statements are made as of the date hereof and the Company disclaims any obligation to update any Forward-looking Statements, whether as a result of new information, future events or results or otherwise, except as required by law. There can be no assurance that these Forward-looking Statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, investors should not place undue reliance on Forward-looking Statements.
