Some of the high-value targets include Kingfisher and Sunbird deep deposits at the Séguéla mine, the Tongon North prospect in northern Cote d´Ivoire, and the Diamba Sud project in Senegal.
The flagship Séguéla mine delivered 137,781 ounces at an AISC of $1,153 per ounce in 2024, in its first full year of gold production. Two-year gold production guidance for 2025 and 2026 has been provided for Séguéla, with incremental production planned to reach 160,000 to 180,000 ounces in 2026 at an AISC in the range of $1,260 to $1,390 per ounce.

Jorge A. Ganoza, President and CEO, commented, “Q4 was a record quarter of free cash-flow at $95.6 million. Quarter over quarter, we realized 7% higher gold prices and 10% higher revenue, while keeping cash cost per ounce flat, leading to expanded operating cash flow margin from 33% to 50%. With the growth in cash flow over the year and a sound balance sheet we returned $30.6 million to shareholders via share buybacks in Q4.” Mr. Ganoza continued “Cost and capital optimization initiatives across the portfolio remains top of mind for management with various opportunities successfully implemented in 2024 and continuing into 2025. The sale of the non-core asset San Jose mine will remove our highest cost ounces and refocuses capital and management´s attention to high-value opportunities in the portfolio. Additionally, the successful optimization of the Séguéla mine is enabling us to plan for increased rates of annual gold production of 160,000 to 180,000 ounces at industry leading costs by 2026, unlocking significant value.”

Fourth Quarter 2024 Results

Q4 2024 vs Q3 2024

Cash cost per ounce and AISC

Cash cost per ounce of gold equivalent (“GEO”) sold was $1,015 in Q4 2024, an improvement of 4% compared to $1,059 over the prior quarter. All-in sustaining costs per GEO was $1,772 in Q4 compared to $1,668 in Q3 2024 due mainly to higher capex in mine development and infrastructure in the quarter related to the expansion of life of mine at Yaramoko and the planned expansion of annual gold production at Séguéla to 160,000 – 180,000 oz by 2026, and timing of capital expenditures.

Attributable Net Income and Adjusted Net Income

Attributable net income for the period was $11.3 million compared to an attributable net income of $50.5 million in Q3 2024. The fourth quarter of 2024 was impacted by non-cash charges of $26.3 million as follows.

A write-down of $14.5 million related to the Boussoura mineral property in Burkina Faso. The majority of the write-down corresponds to the purchase price assigned to Boussoura as part of the Roxgold acquisition and reflects the Company’s view as to Boussoura’s exploration prospects.
A $7.2 million mine closure provision associated with the scheduled closure of the San Jose Mine. Subsequent to the end of the quarter, the Company entered into a binding letter of intent to divest of the San Jose mine. The associated closure provision is expected to unwind upon completion of the sale.
A write-down of low-grade ore stockpiles of $4.6 million at the Lindero Mine.

After adjusting for impairment charges and other non-recurring items, adjusted attributable net income was $37.0 million or $0.12 per share compared to $49.9 million or $0.16 per share in Q3 2024. The decrease was explained by a foreign exchange (“FX”) loss of $10.4 million in Q4 2024 compared to a gain of $3.4 million in Q3 2024, and by a higher effective tax rate (“ETR”) representing approximately $16 million of additional income tax provision over the prior quarter. The main cause of the FX loss and the higher ETR in Q4 was the 8% devaluation of the Euro versus the USD which had an estimated combined impact on earnings per share of 5 cents. This was partially offset by higher sales of $27.3 million, related to a higher realized gold price quarter over quarter and 4% higher gold sold. Realized gold price in Q4 2024 was $2,662 per ounce compared to $2,490 in Q3 2024.

Other items impacting the quarter compared to Q3 2024 were higher Corporate G&A expenditures of $4.4 million related to timing of expenses.

Cash flow

Net cash generated by operations before working capital adjustments was $141.6 million or $0.46 per share. After adjusting for working capital changes, net cash generated by operations for the quarter was $150.3 million compared to $92.9 million in Q3 2024. The increase of $57.4 million reflects higher sales and positive change in working capital in Q4 2024 of $8.6 million compared to negative $26.4 million in Q3 2024, and lower-income tax paid of $7.1 million.

Free cash flow from ongoing operations in Q4 2024 increased $39 million over Q3 2024 to $95.6 million. The increase was due to higher cash generated by operations partially offset by higher capital expenditures of $15.9 million. Free cash flow in Q4 2024, after growth capex of $12.0 million, was $83.6 million.

Q4 2024 vs Q4 2023

Cash cost per ounce and AISC

Consolidated cash cost per equivalent gold ounce was $1,015, compared to the $840 reported in Q4 2023. The increase in cash cost was driven mainly by higher cash cost at Séguéla, and the San Jose Mine operating in its last year of Mineral Reserves. The increase in cash cost at Séguéla is explained mainly by lower head grades in 2024, as per the mine plan, and lower stripping and mining costs during Séguéla’s first semester of operations in 2023. Cash cost also increased at Lindero due to lower production and the impact of the appreciation of the Argentine peso.

All-in sustaining costs per gold equivalent ounce was $1,772 in Q4 2024 compared to $1,416 in Q4 2023. AISC in the quarter includes the $1.4 million annual investment gain (Q4 2023: $12.4 million) from cross border, Argentine pesos denominated bond trades. This is a benefit granted to exporters by the Argentine Government whereby 20% of export proceeds is allowed to be converted into pesos at a preferential exchange rate. This benefit is intended to alleviate exporters for the impact of the overvaluation of the official exchange rate on input costs. The increase in AISC was primarily the result of higher cash cost per ounce as described above and higher sustaining capital at Lindero related to the expansion of the leach-pad. The composition of AISC was revised in Q4 2024 and the comparative periods were updated to reflect the change. Refer to “Non-IFRS Financial Measures – All-in Sustaining Cost Per Gold Equivalent Ounce Sold” on page 27 in the 2024 MD&A for a description of the calculation and the reason for the change.

Attributable Net Income and Adjusted Net Income

Attributable net income for the period was $11.3 million compared to an attributable net loss of $92.3 million in Q4 2023. The fourth quarter of 2024 was impacted by non-cash charges of $26.3 million compared to $118.4 million in the fourth quarter of 2023.

After adjusting for write-downs and other non-recurring items, adjusted attributable net income was $37.0 million or $0.12 per share compared to $20.6 million or $0.07 per share in Q4 2023. The increase was primarily due to higher gold prices. The realized gold price was $2,662 per ounce in Q4 2024 compared to $1,990 per ounce in Q4 2023. This was partially offset by lower gold sales volume and higher cost per ounce. Lower gold sales volume was mainly due to lower production at Séguéla, San Jose, and Lindero. The decrease in production at Séguéla and Lindero was due to lower head grades, in accordance with the mine plan, partially offset by higher processed ore. The higher cost per ounce was explained mainly by the lower head grades at Séguéla and Lindero, lower stripping and mining costs during Séguéla´s second quarter of operations in Q4 2023, and the impact of the appreciation of the Argentine peso at Lindero.

Other items impacting the adjusted net income for the quarter compared to Q4 2023 were a higher unrealized foreign exchange loss of $8.5 million mostly explained by an 8% devaluation of the Euro versus the USD in the period, and lower investment income of $11.0 million related to cross-border, Argentine peso denominated bond trades.

Depreciation and Depletion

Depreciation and depletion decreased $9.0 million to $62.6 million in the fourth quarter of 2024 compared to $71.6 million in the comparable period of 2023. The decrease was primarily due to lower accounting balances at San Jose after a $90.6 million impairment at year end 2023. Depreciation and depletion in the period include $18.2 million related to the purchase price allocation from the Roxgold acquisition at Séguéla.

Cash Flow

Net cash generated by operations for the quarter was $150.3 million compared to $105.1 million in Q4 2023. The increase of $45.2 million reflects higher sales and positive change in working capital in Q4 2024 of $8.7 million compared to nil in Q4 2023, and lower interest paid of $3.2 million.

Free cash flow from ongoing operations for the quarter was $95.6 million compared to $66.2 million in Q4 2023. The increase reflects higher net cash generated by operations.

Full Year 2024 Results

Cash cost per ounce and AISC

Cash cost per equivalent gold ounce was $987, compared to $874 reported in 2023. The increase in cash cost is explained mainly by lower head grades at Séguéla in 2024, and lower stripping and mining costs during Séguéla’s first semester of operations in the second half of 2023, as well as higher cost at San Jose as explained earlier. Cash cost for the full year also increased at Lindero due to lower production and the impact of the appreciation of the Argentine peso.

All-in sustaining costs per gold equivalent ounce was $1,640 in 2024 compared to the $1,480⁴ recorded in the prior year due mainly to higher cash cost per ounce as described above and higher capex mostly at Lindero. AISC for 2024 includes the $9.7 million annual investment gain (FY 2023: $12.4 million) from cross border, Argentine peso denominated bond trades. (See discussion above).

Attributable Net Income and Adjusted Net Income

Attributable net income for the year was $128.7 million, compared to an attributable net loss of $50.8 million in 2023. The loss in 2023 was explained by impairment charges of $90.6 million at the San Jose Mine.

After adjusting for write-downs and other non-recurring items, attributable adjusted net income for 2024 was $144.0 million or $0.47 per share, compared to $64.9 million or $0.22 per share in 2023. The increase was primarily due to higher gold prices and higher gold sales volume. The realized gold price was $2,401 per ounce in 2024 compared to $1,948 per ounce in 2023. Higher gold sales volume was mainly due to the full year contribution of Séguéla upon successful commissioning and ramp-up in Q2 2023, partially offset by lower production at Lindero, aligned with the grade profile in the mine plan, and lower head grades and processed ore at San Jose, in its last year of mineral reserves.

Depreciation and Depletion

Depreciation and depletion for 2024 increased $10.3 million to $230.0 million compared to $219.6 million in 2023. The increase was primarily due to an increase in ounces sold at Séguéla and partially offset by lower depletion expenses at San Jose. Depreciation and depletion in the period include $71.6 million related to the purchase price allocation from the Roxgold acquisition at Séguéla.

Cash Flow

Net cash generated by operations before working capital changes was $438.2 million or $1.42 per share. After adjusting for working capital changes, net cash generated by operations for 2024 was $365.7 million compared to $296.9 million in 2023. The increase of $68.8 million is explained by higher sales partially offset by negative changes in working capital of $72.5 million in 2024 from an increase in receivables of $46.4 million due to timing and delays in repayments of VAT in Burkina Faso and an increase in inventories of $24.5 million related to an increase in ore stockpiles at Lindero and Séguéla. This compares to a negative working capital adjustment of $9.7 million in 2023. Higher taxes paid of $17.7 million was due to Séguéla paying income taxes for the first time in 2024 after initiating commercial production in the second half of 2023.

Free cash flow from ongoing operations for 2024 was $202.9 million compared to $153.5 million in 2023. The increase of $49.4 million reflects higher net cash generated by operations, partially offset by higher sustaining capital expenditures of $14.6 million. Free cash flow in 2024, after growth capex of $44.3 million and the Séguéla NSR repurchase of $6.5 million, was $150.5 million.

Quarterly and Annual Operating and Financial Highlights

During the fourth quarter of 2024, mine production totaled 715,008 tonnes of ore, averaging 2.34 g/t Au, and containing an estimated 53,796 ounces of gold from the Antenna, Ancien, and Koula pits. Movement of waste during the quarter totaled 3,670,138 tonnes, for a strip ratio of 5.1:1. Production was mainly focused from the Antenna pit, which produced 530,651 tonnes of ore, with the balance of production sourced from the Koula and Ancien pits.

In the fourth quarter of 2024, Séguéla processed 430,117 tonnes of ore, producing 35,244 ounces of gold, at an average head grade of 2.95 g/t Au, an 18% decrease and a 19% decrease, respectively, compared to the fourth quarter of 2023. The decrease in gold production was due to lower head grades and lower recovery and partially offset by higher milled tonnes. Plant throughput for the quarter was 208 tonnes per hour (TPH) surpassing the name plate design capacity of 154 TPH by 35%.

Gold production in 2024 totaled 137,781 ounces, achieving the higher end of the annual guidance range. A 75% increase in ounces of gold produced during the year ended December 31, 2024 was mainly due to a full year of production in 2024 compared to only six months in 2023.

Cash cost per gold ounce sold was $653 for the fourth quarter of 2024 and $584 for the full year, compared to $323 for the fourth quarter of 2023 and $357 for the full year of 2023. The increase in cash costs is explained mainly by lower head grades in 2024, as per the mine plan, and lower stripping and mining costs during Séguéla’s first six months of operation in the second half of 2023.

All-in sustaining cash cost per gold ounce sold was $1,376 for the fourth quarter of 2024 compared to $737 in the same period of the previous year. For the full year, the all-in sustaining cash cost was $1,153, compared to $760 in 2023. The increase for the quarter was primarily the result of higher cash costs, higher sustaining capital from higher stripping and the purchase of capital spares as well as lower volume of metal sold. The increase for the year was due to higher cash costs, increased royalties due to higher realized metal prices and higher sustaining capital expenditures.

Brownfields capital expenditures were $6.7 million for the full year in 2024, compared to $nil in 2023, as a result of drilling activities to define the geometry of mineral deposits.

Quarterly and Annual Operating and Financial Highlights

In the fourth quarter of 2024, the Yaramoko Mine treated 102,105 tonnes of ore and produced 29,576 ounces of gold with an average gold head grade of 9.18g/t, 5% and 28% increases when compared to the same period in 2023. Lower tonnage milled was due to 16 days of lost milling time as a consequence of an equipment failure. Higher production in the fourth quarter of 2024 was due to higher grades; partially offset by lower tonnes processed.

Gold production in 2024 totaled 116,206 ounces, achieving the higher end of the annual guidance range.

The cash cost per ounce of gold sold for the quarter ended December 31, 2024, was $812 compared to $949 in the same period in 2023. The decrease for the quarter is mainly attributed to lower mining costs and higher grades. For the year ending December 31, 2024, the cash cost per ounce of gold sold was $860, an increase from $809 in 2023. The full year increase is mainly due to higher mining costs during prior quarters.

The all-in sustaining cash cost per gold ounce sold was $1,302 for the quarter ended December 31, 2024, compared to $1,720 in the same period of 2023. The decrease is mainly due to lower sustaining capital costs, lower cash costs, and an administrative penalty paid in the fourth quarter of 2023. For the full year, the all-in sustaining cash cost was $1,359 in 2024, compared to $1,499 in 2023. The decrease in AISC was mainly the result of lower sustaining capital costs.

Quarterly and Annual Operating and Financial Highlights

In the fourth quarter of 2024, a total of 1,757,290 tonnes of ore were placed on the heap leach pad, with an average gold grade of 0.60 g/t, containing an estimated 34,151 ounces of gold. Gold production for the fourth quarter of 2024 totaled 26,806 ounces. This represents a 9% decrease in total ounces compared to fourth quarter of 2023 as a result of lower grades and lower ounces contained in fine carbon. The mine started placing the first lift of ore on the new leach pad expansion area in the second half of October 2024.

Gold production was comprised of 24,679 ounces in doré bars, 2,086 ounces of gold contained in rich fine carbon, and 41 ounces contained in copper precipitate. Ore mined was 2.1 million tonnes, with a stripping ratio of 1.54:1. For the full year 2024 gold production totaled 97,287 ounces, achieving midpoint of annual production guidance.

The cash cost per ounce of gold for the quarter ending December 31, 2024, was $1,063 compared to $934 in the same period of 2023. For the year ending December 31, 2024, the cash cost per ounce was $1,051, an increase from $920 in 2023. The increase in cash cost per ounce of gold for both the quarter and the full year was primarily due to the impact of appreciation of the Argentine peso, lower gold production and lower by-product credits from copper sales. The increase in cash costs was partially offset by operational efficiency initiatives including a change in the hauling and loading fleet, reduction in cyanide consumption and crushing throughput.

AISC per gold ounce sold during Q4 2024 was $1,873, compared to $1,127 in Q4 2023. AISC in the quarter includes $1.4 million investment gain (Q4 2023: $12.4 million) from cross border, Argentine pesos denominated bond trades. This is a benefit granted to exporters by the Argentine Government whereby 20% of export proceeds are allowed to be converted into pesos at a preferential exchange rate. This benefit is intended to alleviate the impact of the overvaluation of the official exchange rate on input costs. The increase in AISC is explained by higher cash cost and capex in Q4 2024, partially offset by the elimination of the 8% export duty in 2024, and lower investment gains recorded in Q4 2024. The composition of AISC was revised in Q4 2024 and the comparative period was updated to reflect the change. Refer to “Non-IFRS Financial Measures – All-in Sustaining Cost Per Gold Equivalent Ounce Sold” in the 2024 MD&A for a description of the calculation and the reason for the change.

AISC per gold ounce sold in 2024 was $1,793, compared to $1,444 in 2023. AISC for 2024 includes the $9.7 million annual investment gain (FY 2023: $12.4 million) from cross border, Argentine pesos denominated bond trades. AISC per ounce for 2024 was higher due mainly to higher cost per ounce and sustaining capital expenditures related to the leach pad expansion, partially offset by the elimination of export duties in 2024 as described above. The composition of AISC was revised in Q4 2024 and the comparative periods were updated to reflect the change. Refer to “Non-IFRS Financial Measures – All-in Sustaining Cost Per Gold Equivalent Ounce Sold” in the 2024 MD&A for a description of the calculation and the reason for the change.

As of December 31, 2024, the leach pad expansion project was approximately 89% complete. The leach pad expansion remains on schedule for completion during the first half of 2025.

Quarterly and Annual Operating and Financial Highlights

In the fourth quarter of 2024, San Jose produced 594,373 ounces of silver and 4,239 ounces of gold, 42% and 33% decreases respectively, at average head grades for silver and gold of 118 g/t and 0.85 g/t, 19% and 7% decreases respectively, when compared to the same period in 2023. The decrease in silver and gold production for the quarter is explained by the lower extracted mineral and head grades, mainly due to the decreasing grade profile of Mineral Reserves in the mine plan. Annual production in 2024 totaled 2,548,402 ounces of silver and 17,811 ounces of gold, which were 18% and 6% below the lower end of annual guidance range, respectively. Approximately 5% of the lower production for both metals was due to the effect of the iron oxide in the metallurgical recovery. Head grades for the year were aligned with the geological model, albeit slightly lower than expected.

The cash cost per silver equivalent ounce in the fourth quarter of 2024, was $26.01, an increase from $20.45 in the same period of 2023. For the year ended December 31, 2024, the cash cost per silver equivalent ounce sold was $25.25 compared to $14.28 in the same period of 2023. The higher cost per ounce was primarily the result of lower production and silver equivalent ounces sold and previously capitalized costs being expensed.

The all-in sustaining cash cost of payable silver equivalent ounce in the fourth quarter of 2024 increased by 36% to $29.94, and full year 2024 increased 45% to $28.22, compared to $21.98 and $19.40 for the same periods in 2023. These increases were mainly driven by higher cash costs and lower volume of metal sold.

Quarterly and Annual Operating and Financial Highlights

In the fourth quarter of 2024, the Caylloma Mine produced 249,238 ounces of silver at an average head grade of 67 g/t, a 25% and 24% decrease, respectively, when compared to the same period in 2023. Silver production for 2024 totaled 1,176,543 ounces, surpassing the upper end of annual guidance range by 7%.

Lead and zinc production for the quarter was 9.5 million pounds and 13.9 million pounds, respectively. Lead production decreased by 12% and zinc production remained comparable to the same period in 2023. Head grades averaged 3.36% and 4.94%, a 13% and 1% decrease, respectively, when compared to the same quarter in 2023. Lead and zinc production for 2024 totaled 39.6 and 51.9 million pounds, respectively. Lead and zinc production were above the higher end of annual guidance by 33% and 16%, respectively. Increased production is the result of positive grade reconciliation to the reserve model in the lower levels of the underground mine. Gold production in the fourth quarter totaled 128 ounces with an average head grade of 0.11 g/t.

The cash cost per silver equivalent ounce sold in the fourth quarter of 2024, was $16.53 compared to $13.42 in the same period in 2023. For the year ended December 31, 2024, the cash cost per ounce of silver equivalent sold was $14.12, compared to $13.91 in 2023. The higher cost per ounce for the quarter and the year was primarily the result of lower silver production and the impact of higher realized silver prices on the calculation of silver equivalent ounce sold partially offset by lower treatment charges.

The all-in sustaining cash cost per ounce of payable silver equivalent in the fourth quarter of 2024, increased 26% to $28.10, compared to $22.34 for the same period in 2023. The all-in sustaining cash cost per ounce of payable silver equivalent for the full year 2024 was $21.72 compared to $19.90 in 2023. The increase for the quarter and year was the result of higher cash costs per ounce, higher worker’s participation and the impact of higher realized silver prices on the calculation of silver equivalent ounces. If AISC was calculated using the guidance metal prices AISC would have been $23.60 and $19.27 per ounce for the quarter and year respectively.

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.

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” on page 27 in the Company’s management’s discussion and analysis for the year ended December 31, 2024 (“2024 MDA”), and on page 26 of the Company’s management’s discussion and analysis for the nine months ended September 30, 2024 (“Q3 2024 MDA”), which section is incorporated by reference in this news release, for 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, including a description of the change in the composition of AISC which was revised in Q4 2024 and for comparative periods, and the reason for the change. The 2024 MD&A and Q3 2024 MDA may be accessed on SEDAR+ at www.sedarplus.ca under the Company’s profile.

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