Jorge A. Ganoza, President and CEO, commented, “Fortuna has delivered record production and financial results for all its key metrics driven by the first full quarter contribution of our flagship Séguéla gold mine.” Mr. Ganoza continued, “Compared to the first half of the year, the reduction in our consolidated all-in sustaining cost to $1,312 is primarily the result of Séguéla’s industry leading AISC of $788 per ounce, abating inflation, optimization initiatives across the business, and higher gold production at the Yaramoko mine driven by new high grade zones.”  Mr. Ganoza concluded, “As we shift from a two-year capital-intensive phase to strong free cash flow generation, we will prioritize strengthening our balance sheet through debt reduction and advancing high value opportunities in our exploration portfolio. We currently maintain eleven drill rigs turning across our properties including three at our newly acquired Diamba Sud gold project in Senegal.”

Third Quarter 2023 Results

Net income attributable to Fortuna for the quarter was $27.5 million compared to an attributable net loss of $3.7 million in Q3 2022.  After adjusting for non-cash and non-recurring items, adjusted attributable net income for the quarter was $29.6 million compared to $2.9 million in Q3 2022.  The increase in net income and adjusted net income is explained mainly by increased gold sales volume, higher realized gold and silver prices and lower cost of sales per gold equivalent ounce.  Higher gold sales volume was primarily due to the contribution from the first quarter of commercial production at Séguéla and higher grades at Yaramoko.  This was partially offset by lower gold sales volume at Lindero related to lower grades, in line with the mine plan. The realized gold and silver prices were $1,925 and $23.7 per ounce, respectively, in Q3 2023 compared to $1,718 and $19.2 per ounce, respectively, in the prior year.  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 costs of sales per ounce at Lindero and San Jose.  Other items impacting net income in the quarter were higher interest expenses of $5.7 million as a result of interest costs no longer being capitalized in the quarter, higher outstanding debt and increased interest rates; lower depletion at Séguéla which is expected to increase in the coming quarters from depletion of the purchase price; and a low effective income tax rate in the quarter of 17.6% as no income taxes were recorded at  Séguéla.

General and administrative expenses for the quarter of $14.6 million were higher than the same period in 2022 as Séguéla transitioned to operations and costs are no longer being capitalized. G&A is comprised of the following items:

Net cash generated by operations for the quarter increased $41.6 to $106.5 million.  The increase reflects higher EBITDA of $51.2 million offset by lower changes in working capital in Q3 2023 of $0.2 million compared to a change in Q3 2022 of $11.5 million.  Income tax paid in the quarter of $3.2 million was $5.6 million lower than in Q3 2022 as no income tax was paid at Séguéla in Q3 2023.  It is expected Séguéla will start incurring current income taxes in Q4 2023 and paying income taxes in 2024. 

In the third quarter of 2023 capital expenditures on a cash basis was $37.0 million consisting primarily of $30.6 million in sustaining capital, including brownfields exploration, and $4.0 million of non-sustaining exploration.

Free cash flow from ongoing operations for the quarter was $70.0 million, compared to $34.0 million in Q3 2022.  The increase of $36.0 million is the result of higher net cash generated by operations of $41.8 million partially offset by higher sustaining capex and brownfields exploration at our operating mines of $5.8 million in Q3 2023.

Consolidated All-in Sustaining Cost

Consolidated AISC per gold equivalent ounce (GEO) sold for the third quarter of 2023 was $1,312 per ounce compared to $1,431 per ounce for the comparable quarter in 2022. The lower AISC was driven by a decrease of $67 in cash cost of sales per gold equivalent ounce to $814 and lower capital costs per ounce driven by higher volume.

Liquidity

The Company’s total liquidity available as of September 30, 2023 was $162.3 million comprised of $117.8 million in cash and cash equivalents, and $44.5 million undrawn on the $250.0 million revolving credit facility (excluding letters of credit).

Quarterly Operating and Financial Highlights

In the third quarter of 2023, a total of 1,467,578 tonnes of ore were placed on the heap leach pad, with an average gold grade of 0.62 g/t, containing an estimated 29,068 ounces of gold. Gold production for Q3 2023 totaled 20,933 ounces. This represents a 30% decrease in total ounces to the comparable quarter of 2022. This decline in gold production can be primarily explained by the lower head grade of ore placed on the leach pad, in accordance with the mining sequence and the Mineral Reserves. Ore mined was 1.9 million tonnes, with a stripping ratio of 1.1:1. The stripping ratio in the third quarter is 59 percent lower than the second quarter and is expected to continue declining through to the end of the year.

Higher stripping of waste in the first nine months of the year will allow improved access to higher grade material scheduled in the mine plan for the fourth quarter. As a result, Lindero anticipates placing approximately 1.6 million tonnes of ore on the leach pad in Q4 2023 at a higher average grade of 0.67 g/t Au.

Cash cost per ounce of gold for the quarter ended September 30, 2023, was $988 compared to $772 in the same period in 2022. Cash cost per ounce of gold was higher due to lower head grades in line with the mine plan, partially offset by lower processing costs.

All-in sustaining cash cost per gold ounce sold was $1,611 during Q3 2023 compared with $1,159 in the same period of 2022. All-in sustaining cash cost for the third quarter of 2023 was impacted by lower production described above and higher sustaining capital expenditures.

During the quarter, increased sustaining capital expenditures were primarily driven by the development of Phase 2 of the leach pad and capitalized stripping. As of September 30, 2023, the leach pad expansion project (Project) is approximately 13 percent complete. The procurement construction and management (PCM) service has been awarded to Knight Piésold, the accommodation camp expansion and PCM offices for the Project have been finalized, and PCM personnel are already onsite. Mobilization of the contractor’s personnel and equipment has commenced. The first shipments of geomembrane and geosynthetic clay liner are in transit, and the Project remains on schedule for completion during the second half of 2024.

Yaramoko Mine Complex, Burkina Faso

¹ Cash cost and All-in sustaining cash cost are non-IFRS financial measures; refer to non-IFRS financial measures section at the end of this news release and to the MD&A accompanying the Company’s financial statements filed on SEDAR+ at www.sedarplus.ca for a description of the calculation of these measures.

² Capital expenditures are presented on a cash basis.

The Yaramoko Mine produced 34,036 ounces of gold in the third quarter of 2023 with an average gold head grade of 7.72g/t, 25% and 24% increases when compared to the same period in 2022. Increased production resulted from higher average grades and greater widths of mineralization encountered in development headings, which contributed 42% of total mill feed.

As a result of the aforementioned higher grades in development and production zones within the mine plan, the Company has revised Yaramoko’s annual gold production guidance upwards to 110 to 120 thousand ounces from the original guidance of 92 to 102 thousand ounces, an increase of approximately 14 percent. Gold production for the first nine months of 2023 totaled 89,476 ounces.

Cash cost per ounce of gold sold for the quarter ended September 30, 2023, was $752 compared to $934 in the same period in 2022. Cash cost per ounce decreased due to higher production, improved head grades of ore processed, reduced mining costs related to ore development and decreased transportation costs.

All-in sustaining cash cost per gold ounce sold was $1,211 for Q3 2023, compared to $1,630 for the same period in 2022. This decrease was as a result of higher production, and cash cost savings described above.

Sustaining capital for Q3 2023 was higher due to more intensive mine development. Brownfields expenditure was primarily related to diamond drilling. Drilling focused on infill grade control and exploring for extensions beyond the mineralized resource envelope in the deeper eastern portion of Zone 55. During the fourth quarter, drilling will continue on the western portion of Zone 55, testing for up and down-dip continuity of the recently discovered extensions to the resource boundary.

Séguéla Mine, Côte d’Ivoire

¹ Cash cost and All-in sustaining cash cost are non-IFRS financial measures. Refer to Non-IFRS Financial Measures.

² Capital expenditures are presented on a cash basis

From Séguéla’s first gold pour on May 24th to the successful completion of the processing plant performance test in August, the operation is now exceeding nameplate capacity. Séguéla is well positioned to achieve the mid-point of its gold production guidance of 60 to 75 thousand ounces for the second half of 2023.

In the third quarter of 2023, mine production totaled 502,326 tonnes of ore, averaging 3.48 g/t Au, and containing an estimated 56,136 ounces of gold from the Antenna Pit. Movement of waste during the quarter totaled 1,156,540 tonnes, for a strip ratio of 2.3:1.

Cash cost per gold ounce sold was $397 for Q3 2023, which was below plan, primarily higher due to head grades and lower energy and diesel consumption.

All-in sustaining cash cost per gold ounce sold was $788 for Q3 2023, which was below plan, primarily due to lower cash cost, lower capital expenditures, and higher sale volume.

Sustaining capital for Q3 2023 consisted primarily of mine development. The first stage of grade control drilling was completed at the Ancien deposit during the third quarter, with results currently being processed. Construction of the access road continued as planned, with stripping and initial mining of oxide material scheduled to begin this quarter.

At the Koula deposit, initial grade control drilling started and should be completed early this quarter.

San Jose Mine, Mexico

³ Capital expenditures are presented on a cash basis

In the third quarter of 2023, the San Jose Mine produced 1,372,530 ounces of silver at an average head grade of 189 g/t Ag and 8,205 ounces of gold at an average head grade of 1.14 g/t Au, 11% and 10% lower, respectively, when compared to the same period in 2022. The decrease in silver and gold production for the third quarter of 2023, when compared to the third quarter of 2022, is explained by the declining grade profile of Mineral Reserves in the mine plan. The processing plant milled 247,542 tonnes at an average of 2,845 tonnes per day during the third quarter, in line with the plan for the period.

Gold production is expected to fall slightly below the annual guidance range of 34 to 37 thousand ounces, resulting from lost production days in the second quarter due to the illegal union blockade, and gold head grade reconciliation to reserves in the low end of range. The San Jose Mine remains positioned to deliver annual silver production within the guidance range of between 5.3 to 5.8 million ounces.

The cash cost per tonne for the three months ended September 30, 2023, was $103.47 compared to $79.37 in the same period in 2022. The increase was primarily due to higher use of contractors to make up for lost production in the second quarter of 2023 related to the illegal blockade, higher maintenance and indirect costs and the appreciation of the Mexican Peso.

All-in sustaining cash cost of payable silver equivalent for the three months ended September 30, 2023, increased 26% to $18.04 per ounce, compared to $14.23 per ounce for the same period in 2022. The increase was driven by higher cash cost, lower production, and lower equivalent silver ounces per gold ounce. This was offset slightly by lower capital expenditures and lower workers’ participation costs.

In the third quarter of 2023, sustaining capital expenditures were higher than the same period in 2022. This increase was primarily due to the execution of development meters, which had been postponed from Q2 2023 because of the blockade. Brownfields expenditures were in line with the plan. Expenditures are however expected to increase, due to the emergent drilling campaign at the Yessi vein.

Infill drilling at the San Jose Mine during the quarter led to the discovery of the Yessi vein, a blind structure, located 200 horizontal meters from existing underground infrastructure. The discovery hole SJOM-1387 intersected 1,299 g/t Ag Eq over 9.9 meters, and drill hole SJOM-1391 intersected 621 g/t Ag Eq over 5 meters (Refer to the News Release filled on SEDAR+ on September 5, 2023 titled “Fortuna intersects 1,299 g/t Ag Eq over a true width of 9.9 meters at the San Jose Mine, Mexico” for full details of the drilling program). Additional drilling is currently underway from both surface and underground to define the extent and geometry of this discovery. Mineralization remains open along strike to the north and south, and at depth.

³ Capital expenditures are presented on a cash basis.

The Caylloma Mine produced 308,221 ounces of silver, 10.3 million pounds of lead, and 14.0 million pounds of zinc during the third quarter of 2023. Silver production was 6% higher compared to the same quarter in 2022. Lead and zinc production rose by 14% and 18% respectively, compared to the same period in 2022. Increased production was the result of positive grade reconciliation to the reserve model in levels 16 and 18 of the Animas vein. Increased recoveries for lead and zinc were also driven by the higher grades. Gold production totaled 149 ounces with an average head grade of 0.13 g/t.

The cash cost per tonne of processed ore for the three months ended September 30, 2023, increased 7% to $99.25 compared to $93.12 in the same period in 2022. This increase was primarily due to higher processing and indirect costs.

The all-in sustaining cash cost per ounce of payable silver equivalent for the three months ended September 30, 2023, increased 35% to $21.14, compared to $15.66 for the same period in 2022. The increase was driven by higher cash cost and the impact of metal prices on the calculation of silver equivalent ounces.

Capital costs for the period mainly consisted of underground development in mine levels 15, 16, and 18. The increase in Brownfields expenditures is primarily attributable to additional long hole drilling.

Forward-looking Statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any results, performance or achievements expressed or implied by the Forward-looking Statements. Such uncertainties and factors include, among others, changes in general economic conditions and financial markets; uncertainty relating to new mining operations such as the Séguéla Mine, including the possibility that actual capital and operating costs and economic returns will differ significantly from those estimated for such projects prior to production;   risks associated with war or other geo-political hostilities, such as the Ukrainian – Russian conflict, any of which could continue to cause a disruption in global economic activity; fluctuation in currencies and foreign exchange rates; increases in the rate of inflation; the imposition or any extension of capital controls in countries in which the Company operates; any changes in tax laws in Argentina and the other countries in which we operate; changes in the prices of key supplies; technological and operational hazards in Fortuna’s mining and mine development activities; risks inherent in mineral exploration; uncertainties inherent in the estimation of mineral reserves, mineral resources, and metal recoveries; changes to current estimates of mineral reserves and resources; changes to production and cost estimates; the possibility that the ruling in favour of Compania Minera Cuzcatlan S.A. de C.V. (“Minera Cuzcatlan”) to reinstate the environmental impact authorization at the San Jose mine (the “EIA”) will be successfully appealed; changes in the position of regulatory authorities with respect to the granting of approvals or permits; governmental and other approvals; changes in government, political unrest or instability in countries where Fortuna is active; labor relations issues; as well as those factors discussed under “Risk Factors” in the Company's Annual Information Form. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in Forward-looking Statements, there may be other factors that cause actions, events or results to differ from those anticipated, estimated or intended. 

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, labour 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; if an appeal is made in respect of the ruling in favour of Minera Cuzcatlan reinstating the EIA, that such appeal won’t be successful; that Minera Cuzcatlan will be successful in the legal proceedings to reinstate the environmental impact authorization at the San Jose mine; 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.
