Mineros Reports Fourth Quarter 2024 Financial and Operating Results

Mineros S.A. (TSX:MSA, MINEROS:CB) (“Mineros” or the “Company”) today reported its financial and operating results for the three months and year ended December 31, 2024. All dollar amounts - other than per share amounts - are expressed in thousands of US dollars unless otherwise stated. For further information, please see the Company’s audited consolidated financial statements and management’s discussion and analysis posted on Mineros’ website https://mineros.com.co/en/investors/financial-reports and filed under its profile on www.sedarplus.com.

Andrés Restrepo, President and Chief Executive Officer of Mineros, commented: “We are very pleased with our results for the fourth quarter and year-ended December 31, 2024. From a financial perspective, high and rising gold prices provided us with record revenues and record profits for 2024 of $538.6M and $86.6M from the production and sale of 213,245 ounces of gold at an average price $2,387. Net earnings per share were $0.29. From an operational perspective our Hemco operation is running smoothly and our partnership with artisanal miners under the Bonanza model continues to deliver excellent results aligned with our vision of bringing benefit to all stakeholders thereby allowing us to produce close to the top end of our guidance. Our Nechí Alluvial operation met revised guidance for annual production. We continue to implement various efficiency measures to improve production. We are proud of the work we do in the El Bagre area and continue to effect positive change in the lives of locals through participation in formalizing some informal miners working alongside us. Cash Cost and all-in sustaining costs were in line for Nechí and just above the higher end of guidance for Hemco because of the very strong gold price.”

2024 Performance and 2025 Guidance

The Company achieved its revised production guidance for 2024 with the production of 213,245 ounces of gold, above the midpoint of the guided range. The Company had adjusted guidance in the third quarter of 2024 to better give stakeholders an idea of how the Nechí Alluvial Property and the Hemco Property were each performing against guidance, and to provide better information as to where Cash Cost per ounce of gold sold and AISC per ounce of gold sold were trending. For 2025, we expect gold production to be between 201,000 and 223,000 ounces, building on the consistent performance of our Nicaragua underground mines and partnerships with artisanal miners and the diligence with which our teams at the Nechí Alluvial Property resolve issues as they arise. We remain focused on operational excellence and delivering strong, reliable returns for our shareholders.

The following table summarizes the Company’s production performance relative to 2024 guidance, and 2025 guidance:

1. Guidance for silver is not provided by the Company, as we treat it as a by-product and the volumes of silver are rather small relative to gold production.
2. 2024 guidance was revised in November 2024 to reflect lower grades recovered at the Nechí Alluvial Property, and higher artisanal production at the Hemco Property, as disclosed in the Company’s news release dated November 13, 2024, titled “Mineros Reports Third Quarter 2024 Financial and Operating Results”.

The following table summarizes the Company’s cash cost and AISC performance relative to 2024 guidance, and 2025 guidance:

1. 2024 guidance was revised in November 2024 to reflect lower grades recovered at the Nechi Alluvial Property, and higher artisanal production at the Hemco Property, as disclosed in the Company’s news release dated November 13, 2024, titled “Mineros Reports Third Quarter 2024 Financial and Operating Results”.
2. These measures are forward-looking non-IFRS financial measures. Guidance for 2025 Cash Cost per ounce of gold sold and AISC per ounce of gold sold assume an average realized gold price of $2,600/oz, and a exchange rate COP/USD of COP$4,200, and inflation of 6,5%. For further information concerning the equivalent historical non-IFRS financial measures, see Section 10 – Non-IFRS and Other Financial Measures in this MD&A.
3. The composition of Cash Cost per ounce of gold sold and AISC per ounce of gold sold were revised in Q2 of 2024. See Section 10 – Non-IFRS and Other Financial Measures in this MD&A.
4. The composition of Cash Cost per ounce of gold sold for the Nechi Alluvial Property was revised in Q4 of 2024. See Section 10 – Non-IFRS and Other Financial Measures in this MD&A.

Further to the Company's January 25, 2025 news release, the composition of Cash Cost for the Nechi Alluvial Property (Colombia) segment was revised in the fourth quarter of 2024 to exclude an intercompany royalty between the Company and its subsidiary, Mineros Aluvial S.A.S. BIC, aligning the composition of those measures for reporting historical performance with the composition of those measures used in disclosing the Company's guidance. This reduces Cash Cost and Cash Cost per ounce of gold sold for that segment. The Company notes that guidance provided for the Nechi Alluvial Property (Colombia) segment has always excluded the intercompany royalty, even though disclosure of historical Cash Cost performance for the segment did not, which resulted in an inconsistency in reporting of this measure between guidance and historical measures, which has now been addressed. The Company clarifies that all guidance and all historical calculations of Cash Cost and AISC on a consolidated basis previously disclosed by the Company have excluded the effect of this intercompany royalty, and accordingly, they have not been affected by this change.

Annual gold production for 2025 at the Nechí Alluvial Property is expected to be between 81,000 and 91,000 ounces. At the Nechí Alluvial Property, the Company anticipates Cash Cost per ounce of gold sold and AISC per ounce of gold sold to increase slightly compared with 2024 due to inflationary pressures.

At the Hemco Property, the Company anticipates annual production in 2025 of 120,000 to 132,000 ounces of gold, including 87,000 to 96,000 ounces of gold from artisanal production. We have cultivated strong relationships with the artisanal mining community, creating a strategic advantage in sourcing gold. This collaborative approach ensures consistent access to high-quality minerals, allowing us to maintain stable production levels and deliver on our guidance commitments with greater confidence. The Company anticipates both Cash Cost per ounce of gold sold and AISC per ounce of gold sold to increase due to higher assumed gold prices resulting in 2025, which would increase the cost of artisanal production.

FINANCIAL AND OPERATING HIGHLIGHTS FOR THE THREE MONTHS AND YEAR-ENDED DECEMBER 31, 2024

The following table summarizes quarterly financial highlights for the three months and year ended December 31, 2024 and 2023.

1. Average realized price per ounce of gold sold, average realized price per ounce of gold sold from continuing operations, average realized price per ounce of gold sold from discontinued operations, Adjusted EBITDA, Cash Cost per ounce of gold sold from continuing operations, AISC per ounce of gold sold from continuing operations, net free cash flow and Net Debt are non-IFRS financial measures, and ROCE is a non-IFRS ratio, with no standardized meaning under IFRS, and therefore may not be comparable to similar measures presented by other issuers. For further information and detailed reconciliations to the most directly comparable IFRS measures, see Non-IFRS and Other Financial Measures in this news release.

Financial Highlights for the three months ended December 31, 2024

• Revenue increased by 15%: Revenue totaled $150,158 during the fourth quarter of 2024, compared with $130,427 in the fourth quarter of 2023, with sales of gold of $144,239 at an average realized price per ounce of gold sold from continuing operations of $2,662, during the fourth quarter of 2024, compared with sales of gold of $122,530 at an average realized price per ounce of gold sold from continuing operations of $1,975 in the same period in 2023. The increase in revenue in the fourth quarter of 2024 is due to a 35% increase in the average realized price per ounce of gold sold from continuing operations, offset by a 13% decrease in ounces of gold sold, and a 25% decrease in sales of silver of $1,149;

• Cost of sales increased by 16% to $95,664 during the fourth quarter of 2024, compared with $82,663 in the fourth quarter of 2023. This increase was primarily due to: (i) the higher price of gold increasing the costs to purchase ore from artisanal miners by $5,385; (ii) higher operating expenses across the Company’s operations generally, increased maintenance and materials cost of $3,997, and service and labour costs of $258 and $1,108 respectively. At the Nechí Alluvial Property the Company made a provision of $1,450 for environmental rehabilitation and took a non-cash impairment of certain assets of $2,162.

• Gross Profit from continuing operations increased by 14% to $54,494 in the fourth quarter of 2024, compared with $47,764 in the fourth quarter of 2023, mainly due to higher revenue as noted above;

• Profit for the period from continuing operations was flat at $23,195 or $0.08 per share during the fourth quarter of 2024 compared with $22,808 or $0.08 per share during the fourth quarter of 2023.

• Adjusted EBITDA up 7%: Adjusted EBITDA was $56,895 during the fourth quarter of 2024 compared with $53,364 during the fourth quarter of 2023, mainly due to the higher revenue;

• Net cash flows generated by operating activities were up 38%, totaling $73,221 in the fourth quarter of 2024, compared with $52,932 in the fourth quarter of 2023. The Company’s net free cash flow was positive for the three months ended December 31, 2024 and totaled $56,706, up from $36,761 in the same period of 2023, mainly due to $29,762 higher receipts from sales of goods and other revenue, offset with higher payments to suppliers during the quarter of $8,070;

• Dividends Paid up 43%: Dividends paid during the fourth quarter of 2024 were $7,475, compared with $5,228 in the same period of 2023, due to the extraordinary dividend approved at the ordinary meeting of the General Shareholders’ Assembly in March 2024;

• Capital investments¹ up 8%: During the fourth quarter of 2024, capital investments of $27,316 were made into existing mines, and exploration and growth projects, compared with $25,242 in the fourth quarter of 2023; the increase is due to the construction of a new tailings impoundment facility at the Hemco Property; and

• Cash Cost & AISC: Cash Cost per ounce of gold sold from continuing operations in the fourth quarter of 2024 was $1,408 and AISC per ounce of gold sold from continuing operations was $1,775, compared with Cash Cost per ounce of gold sold from continuing operations of $1,018 and AISC per ounce of gold sold from continuing operations of $1,316 for the fourth quarter of 2023. The 38% increase in Cash Cost per ounce of gold sold from continuing operations is mainly explained by the 16% increase in the cost of sales, due to higher gold prices, partially offset by the 13% decrease in ounces of gold sold. The increase in AISC per ounce of gold sold from continuing operations is explained by the increase in the Cash Costs per ounce of gold sold from continuing operations, along with a (12)% increase in sustaining capital expenditures.²

Financial Highlights for year ended December 31, 2024

• Revenue increased by 20%: revenue totaled $538,566 during the year ended December 31, 2024, compared with $447,290 in the year ended December 31, 2023, with sales of gold of $508,965 at an average realized price per ounce of gold sold from continuing operations of $2,387 in the year ended December 31, 2024, compared with sales of gold of $425,647 at an average realized price per ounce of gold sold from continuing operations of $1,937 in the year ended December 31, 2023;

• Cost of sales increased by 17%, to $354,567 in the year ended December 31, 2024, compared with $301,888 in the year ended December 31, 2023; the increase in costs is primarily due to higher cost of purchasing artisanal material of $24,470 due to higher gold prices, higher labour costs of $6,645, higher services of $5,279 and higher taxes and royalties of $569;

• Gross Profit from continuing operations increased by 27%, amounting to $183,999 in the year ended December 31, 2024, compared with $145,402 in the year ended December 31, 2023; mainly due to a 20% increase in revenue, due to higher gold prices, which was partially offset by a 17% increase in cost of sales as explained above;

• Profit for the period from continuing operations was up by 16% to $86,552 or $0.29 per share during the year ended December 31, 2024 compared with $74,538 or $0.25 per share during the year ended December 31, 2023; the increase in profit is mainly explained by the increase in gross profit, partially offset by an increase in costs as mentioned earlier. Profit was negatively impacted by higher deferred taxes of $16,414 and higher current taxes of $10,562;

• Adjusted EBITDA up 22%: Adjusted EBITDA was $210,099 during the year ended December 31, 2024 compared with $172,146 during the year ended December 31, 2023 due to a 20% increase in revenue, offset by a 17% increase in cost of sales and a 22% increase in administrative expenses, a 55% decrease in other income offset with a 115% increase in foreign exchange difference, due to the appreciation of the Colombian peso against the U.S. dollar;

• Loss for the period from discontinued operations decreased by 100%, to $0 during the year ended December 31, 2024, compared with a loss of $57,324 during the year ended December 31, 2023, due to the sale of the Gualcamayo Property;

• ROCE was 37% as at December 31, 2024 compared with ROCE of 30% as at December 31, 2023; the increase is mainly explained by 22% higher Adjusted EBITDA for the last 12 months, along with a 5% increase in average capital employed, mainly explained by lower gold inventories after the sale of the Gualcamayo Property, fewer exploration and evaluation projects and lower value attributable to property, plant and equipment;

• Net Debt was $(70,483) as at December 31, 2024, compared with $(24,316) as at December 31, 2023; explained by 41% higher cash and cash equivalents, along with 27% lower loans and other borrowings;

• Dividends Paid up 35%: Dividends paid were $27,663 during the year ended December 31, 2024, compared with $20,519 in the same period of 2023, explained by an extraordinary annual dividend approved at the ordinary meeting of the General Shareholders’ Assembly in March 2024;

• Net cash flows generated by operating activities were up 60% totaling $144,192 in the year ended December 31, 2024, compared with $89,908 in the same period of 2023. The Company’s net free cash flow was positive for the year ended December 31, 2024 and totaled $86,807, up from $49,202 in the same period of 2023, due to lower receipts from sales of goods and other revenue of $14,917, lower payments to suppliers of $23,319 and lower payments to employees of $18,309 offset by higher income tax payments of $3,904;

• Capital investments up 15% to $75,919: During the year ended December 31, 2024 capital investments of $75,919 were made into existing mines, and exploration and growth projects, compared with $66,205 in the year ended December 31, 2023. The increase is explained by the construction of a new tailings impoundment facility at the Hemco Property; and

• Cash Cost & AISC: Cash Cost per ounce of gold sold in the year ended December 31, 2024 was $1,282 and AISC per ounce of gold sold was $1,551, compared with Cash Cost per ounce of gold sold of $1,066 and AISC per ounce of gold sold of $1,299 for the same period in 2023. The 20% increase in Cash Cost per ounce of gold sold was mainly explained by 19% higher cost of sales, due to higher gold prices, the 6% devaluation of the US dollar against the Colombian peso and 3% more ounces of gold sold. The 19% increase in AISC per ounce of gold sold is explained by the increase in Cash Cost per ounce of gold sold and a 6% increase in sustaining capital expenditures.

Operational Highlights by Material Property

The following table sets forth the gold produced for the continuing and discontinued operations of the Company for the three months and year ended December 31, with a discussion of the operational highlights for each of the three months ended December 31, 2024, following the table.

(All numbers in ounces unless otherwise noted)

Operational Highlights for the three months ended December 31, 2024

• Gold production decreased by 13%: Excluding the results of the discontinued operations at the Gualcamayo Property (disposed of in 2023), 54,189 ounces of gold were produced during the fourth quarter of 2024, compared with 62,039 ounces in the fourth quarter of 2023. The decrease in production is mainly a result of 7% lower production at the Hemco Property and 19% lower production at the Nechí Alluvial Property.

• Exploration and Evaluation Expenditures: for the three months ended December 31, 2024, the Company incurred $3,777 in exploration and evaluation (“E&E”) expenditures, a decrease of 40.7% compared with the fourth quarter of 2023. Regional exploration in the Hemco Property was at similar levels in both periods. The following table summarizes E&E expenditures for the current and comparative periods. The very modest increase in exploration expenses is mainly due to regional exploration in the Hemco Property.

GROWTH AND EXPLORATION PROJECT UPDATES

Near Mine Exploration, Hemco Property Expansion

Near mine exploration is focused on the current mining operations, the Panama Mine and the Pioneer Mine. Mineralization is related to an epithermal gold system associated with multiple quartz veins.

A diamond drill program totaling 134 holes and 37,860 metres was completed in 2024. The objective of this campaign was to increase the Mineral Resources and Mineral Reserves at the Panama Mine and the Pioneer Mine. In the fourth quarter of 2024, the drill program advanced at the Panama Mine and the Pioneer Mine, with 7,829 metres of drilling completed in 29 holes. A total of 4,004 metres were drilled at the Panama Mine and 3,825 metres at the Pioneer Mine. The Company faced delays in its drilling program due to mechanical issues with the drilling rigs.

For 2025, the Company has planned a diamond drilling campaign of approximately 30,000 metres to expand the current Mineral Resources and Mineral Reserves. A total of 17,500 metres is planned for the Panama Mine and 12,500 metres for the Pioneer Mine.

Brownfield Exploration, Hemco Property Expansion

Brownfield exploration is centered on the Bonanza block, which encompasses the concession areas between the Panama Mine and the Pioneer Mine. The mineralization belongs to the same epithermal gold trend that comprises the Panama and Pioneer mines, characterized by multiple quartz veins.

For 2025, Mineros has planned an 18,000 metre diamond drilling campaign to mainly evaluate two brownfield targets, Cleopatra and Orpheus. The objective of this drilling campaign aligns with the Company's strategic plan to ensure the mineral resources being mined at the Panama and Pioneer mines are replaced.

Porvenir Project

The Porvenir Project is a pre-development stage project located 10.5 km southwest of the existing Hemco Property facilities. Mineralization consists of a volcanic hosted gold-zinc-silver deposit with epithermal quartz veins of intermediate sulphidation.

In 2024, Mineros completed work to evaluate alternative mining methods for the Porvenir Project to improve extraction efficiency and reduce costs, including through the analysis of alternative geometallurgical assumptions and analysis of metallurgical test work results, which allowed for the refinement of the geometallurgical model for the Porvenir Project, completed in fourth quarter of 2024. This work was guided by the findings of the geomechanical study which was also completed in 2024.

The Company is updating the Mineral Resources and Reserves for the Porvenir Project to maximize its value, with the prefeasibility study optimization scheduled for completion in 2025.

Guillermina Target

The Guillermina target is an epithermal zinc-gold-silver deposit, located four kilometers west of the Pioneer deposit.

A total of 40 holes comprising 6,498 metres of diamond drilling was completed in 2024, achieving 100% of the original plan.

For 2025, Mineros has planned a 2,000-meter diamond drilling campaign to collect material for metallurgical testing and to conduct infill drilling on current inferred resources, with the aim of upgrading them to the category of Indicated Mineral Resource as such term is defined under NI 43-101.

Leticia Deposit

The Leticia Deposit is an epithermal gold-silver-zinc deposit, located 500 m northwest of the Porvenir Project.

For 2025, Mineros has planned a 1,300-meter diamond drilling campaign focused on infill drilling of current Inferred Mineral Resources, with the goal of upgrading them to the Indicated Mineral Resource category.

Luna Roja Deposit

The Luna Roja Deposit is a skarn gold system, located 24 km southeast from the existing Hemco facilities. The Company is focusing on expanding the current Mineral Resources and identifying new targets surrounding the main deposit.

In the fourth quarter of 2024, internal metallurgical testing at the Hemco Lab, along with all technical work and analysis for updating the Mineral Resource estimate for the Luna Roja Deposit, was completed. The updated estimate has been reviewed by SLR Consulting (Canada) Ltd., with publication planned for 2025.

The Company carried out fieldwork targeting geophysical anomalies in the fourth quarter of 2024. Due to the limited presence of outcrops in the area, additional geophysical analysis and drilling are required to support further investigations.

No drilling activities are scheduled for the Luna Roja Deposit in 2025.

Hemco Property Regional Exploration

Mineros' regional greenfield exploration is focused on two areas with early-stage targets: Rosita and Bonanza districts. The Bonanza district excludes the designated brownfield area known as the Bonanza block, see Brownfield Exploration, Hemco Property Expansion.

A total of 10 holes comprising 1,374 metres of diamond drilling was completed in the fourth quarter of 2024, achieving approximately 92% of the original plan at the Okonwas Target, part of the Rosita I concession. Assay results are expected to be received in the first quarter of 2025, however, preliminary observations indicate multiple semi-parallel thin veins containing chalcopyrite, sphalerite and galena, suggesting a gold-zinc-silver mineralization.

For 2025, Mineros adjusted its regional drilling strategy to align with the Company’s strategic plan, which prioritizes replacing Mineral Resources at the Panama and Pioneer Mines. For greenfield exploration, efforts will be concentrated on two key areas:

• Rosita District: This area encompasses targets that primarily shows gold-silver mineralization identified through historical mining, artisanal activities, surface sampling, and scout drilling. Current exploration efforts are centered on the Silba, Bambanita, and Rosita I targets, that includes Okonwas and Murcielago.

• Bonanza District: This area includes targets that have demonstrated gold-silver-zinc mineralization through historical mining, artisanal activities, and surface sampling. Current reconnaissance efforts are focused on the Araica, Experiencia, Pis Pis, Colonia Norte, San Ramón, and Constancia targets.

A 14,500-meter drilling campaign is planned for 2025, with approximately 6,000 meters allocated for exploration in the Rosita District and 8,500 meters in the Bonanza District.

Near Mine Exploration, Nechí Alluvial Property Expansion

At the Nechí Alluvial Property, Mineros is exploring for alluvial gold predominantly east of the Nechí River, where the Company is currently mining within quaternary alluvial sediments.

A total of 14,910 metres in 531 holes were completed in 2024, approximately 50% higher than the Company’s original drilling plan. A total of 3,132 metres in 101 holes were drilled in the fourth quarter of 2024, with 390 metres focused on Mineral Resource expansion and 2,742 metres of infill drilling in the current production area. From the total, 892 metres in 31 holes of ward drilling and 2,240 metres in 70 holes of sonic drilling were completed.

In 2024, Mineros increased infill drilling to improve Mineral Resource estimates and reduce geological uncertainty in the current production zone.

In early 2024, Mineros carried out reconnaissance drilling at the Río Cauca target as part of its regional exploration strategy. Using sonic drilling, 681 m were completed across two concessions (503244 and 503248) to evaluate the potential of quaternary sedimentary units, including terraces and alluvial plains, for hosting economically viable gold deposits.

A 10,000 metre-drilling campaign is planned for 2025, where approximately 4,750 metres are designed to expand the current Mineral Resources, 5,000 metres of infill drilling in the production areas and 250 metres of continuing reconnaissance drilling at the Río Cauca Target. From the total, 3,300 metres of ward drilling and 6,700 metres of sonic drilling are planned.

NON-IFRS AND OTHER FINANCIAL MEASURES

The Company has included certain non-IFRS financial measures and non-IFRS ratios in this news release. Management believes that non-IFRS financial measures and non-IFRS ratios, when supplementing measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-IFRS financial measures and non-IFRS ratios do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies. This data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. For a discussion of the use of non-IFRS financial measures and reconciliations thereof to the most directly comparable IFRS measures, see below.

EBIT, EBITDA and Adjusted EBITDA

The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use earnings before interest and tax (“EBIT”), earnings before interest, tax, depreciation and amortization (“EBITDA”), and adjusted earnings before interest, tax, depreciation and amortization (“Adjusted EBITDA”), which excludes certain non-operating income and expenses, such as financial income or expenses, hedging operations, exploration expenses, impairment of assets, foreign currency exchange differences, and other expenses (principally, donations, corporate projects and taxes incurred). The Company believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results because it is consistent with the indicators management uses internally to measure the Company’s performance and is an indicator of the performance of the Company’s mining operations.

The following table sets out the calculation of EBIT, EBITDA and Adjusted EBITDA to Net profit for the three months and years ended December 31, 2024, and 2023:

1. For additional information regarding taxes, see note 21 of our audited consolidated financial statements, for the three months and years ended December 31, 2024 and 2023.
2. Composition of Adjusted EBITDA was revised in the third quarter of 2023 to include loss for the year from discontinued operations.
3. The reconciliation above does not include adjustments for (impairment) reversal of assets, because there would be a nil adjustment for the three months and years ended December 31, 2024 and 2023.

Cash Cost

The objective of Cash Cost is to provide stakeholders with a key indicator that reflects as close as possible the direct cost of producing and selling an ounce of gold.

The Company reports Cash Cost per ounce of gold sold which is calculated by deducting revenue from silver sales, depreciation and amortization, environmental rehabilitation provisions and including cash used for retirement obligations and environmental and rehabilitation and sales of electric energy. This total is divided by the number of gold ounces sold. Cash Cost includes mining, milling, mine site security, royalties, and mine site administration costs, and excludes non-cash operating expenses. Cash Cost per ounce of gold sold is a non-IFRS financial measure used to monitor the performance of our gold mining operations and their ability to generate profit, and is consistent with the guidance methodology set out by the World Gold Council.

The following table provides a reconciliation of Cash Cost per ounce of gold sold on a by-product basis to cost of sales for the three months and years ended December 31, 2024, and 2023:

1. Refers to cost of sales incurred in the Company’s “Others” segment. See note 7 of our audited consolidated financial statements for the three months and years ended December 31, 2024 and 2023. The majority of this amount relates to the cost of sales of latex.

Changes in Composition of Cash Cost

The composition of Cash Cost from continuing operations was revised in the fourth quarter of 2023 to adjust for asset retirement obligations and environmental rehabilitation provisions in connection with the sale of the Gualcamayo Property. Values for prior periods have been adjusted from amounts previous disclosed to reflect these changes.

The composition of Cash Cost was revised in the second quarter of 2024 to deduct revenue from sales of electric energy from cost of sales to better reflect the costs to produce an ounce of gold. Values for prior periods have been adjusted from amounts previous disclosed to reflect these changes.

Changes in Composition of Cash Cost - Nechí Alluvial Property (Colombia) Segment

The composition of Cash Cost for the Nechí Alluvial Property (Colombia) segment was revised in the fourth quarter of 2024 to exclude an intercompany royalty, which reduces Cash Cost and Cash Cost per ounce of gold sold for that segment. The Company notes that guidance provided for the Nechí Alluvial Property (Colombia) segment has always excluded the intercompany royalty, even though disclosure of historical Cash Cost performance for the segment did not, which resulted in an inconsistency in reporting of this measure between guidance and historical measures. Disclosure of Cash Cost and Cash Cost per ounce of gold sold for the Nechí Alluvial Property (Colombia) segment has been adjusted from amounts previously disclosed in historical MD&A to reflect this change. For greater certainty, this change does not affect Cash Cost and Cash Cost per ounce of gold sold of the Company on a consolidated basis, or for any other segment.

All-in Sustaining Costs

The objective of AISC is to provide stakeholders with a key indicator that reflects as close as possible the full cost of producing and selling an ounce of gold. AISC per ounce of gold sold is a non-IFRS ratio that is intended to provide investors with transparency regarding the total costs of producing one ounce of gold in the relevant period.

The Company reports AISC per ounce of gold sold on a by-product basis. The methodology for calculating AISC per ounce of gold sold is set out below and is consistent with the guidance methodology set out by the World Gold Council. The World Gold Council definition of AISC seeks to extend the definition of total Cash Cost by deducting cost of sales of non-mining operations and adding administrative expenses, sustaining exploration, sustaining leases and leaseback and sustaining capital expenditures. Non-sustaining costs are primarily those related to new operations and major projects at existing operations that are expected to materially benefit the current operation. The determination of classification of sustaining versus non-sustaining requires judgment by management. AISC excludes current and deferred income tax payments, finance expenses and other expenses. Consequently, these measures are not representative of all the Company’s cash expenditures. In addition, the calculation of AISC does not include depreciation and amortization cost or expense as it does not reflect the impact of expenditures incurred in prior periods. Therefore, it is not indicative of the Company’s overall profitability. Other companies may quantify these measures differently because of different underlying principles and policies applied. Differences may also occur due to different definitions of sustaining versus non-sustaining.

The following table provides a reconciliation of AISC per ounce of gold sold to cost of sales for the three months and years ended December 31, 2024, and 2023:

1. Cost of sales of non-mining operations is the cost of sales excluding cost incurred by non-mining operations and the majority of this cost comprises cost of sales of latex.
2. Depreciation and amortization of administrative expenses is included in the administrative expenses line on the audited consolidated financial statements and is mainly related to depreciation for corporate office spaces and local administrative buildings at the Hemco Property.
3. Represents most lease payments as reported in the audited consolidated financial statements of cash flows and is made up of the principal of such cash payments, less non-sustaining lease payments. Lease payments for new development projects and capacity projects are classified as non-sustaining.
4. Sustaining exploration: Exploration expenses and exploration and evaluation projects as reported in the audited consolidated financial statements, less non-sustaining exploration. Exploration expenditures are classified as either sustaining or non-sustaining based on a determination of the type and location of the exploration expenditure. Exploration expenditures within the footprint of operating mines are considered costs required to sustain current operations and so are included in sustaining costs. Exploration expenditures focused on new ore bodies near existing mines (i.e. brownfield), new exploration projects (i.e. greenfield) or for other generative exploration activity not linked to existing mining operations are classified as non- sustaining.
5. Sustaining capital expenditures: Represents the capital expenditures at existing operations including, periodic capitalized stripping and underground mine development costs, ongoing replacement of mine equipment and overhaul of existing equipment, and is calculated as total additions to property, plant and equipment (as reported on the consolidated statements of cash flows), less non-sustaining capital. Non-sustaining capital represents capital expenditures for major projects, including projects at existing operations that are expected to materially benefit the operation and provide a level of growth, as well as enhancement capital for significant infrastructure improvements at existing operations. Non-sustaining capital expenditures during the three months and year ended December 31, 2024, are primarily related to major projects at the Hemco Property and the Nechí Alluvial Property. The sum of sustaining capital expenditures and non-sustaining capital expenditures is reported as the total of additions of property plant and equipment in the audited consolidated financial statements

Changes in Composition of AISC

The composition of AISC from continuing operations and AISC per ounce of gold sold from continuing operations was revised in the fourth quarter of 2023 to adjust for asset retirement obligations and environmental rehabilitation provisions in connection with the sale of the Gualcamayo Property. Values for prior periods have been adjusted from amounts previous disclosed to reflect these changes.

Changes in Composition of AISC - Nechí Alluvial Property (Colombia) Segment

The composition of AISC for the Nechí Alluvial Property (Colombia) segment was revised in the fourth quarter of 2024 to exclude an intercompany royalty, which reduces AISC and AISC per ounce of gold sold for that segment. The Company notes that guidance provided for the Nechí Alluvial Property (Colombia) segment has always excluded the intercompany royalty, even though disclosure of historical AISC performance for the segment did not, which resulted in an inconsistency in reporting of this measure between guidance and historical measures. Disclosure of AISC and AISC per ounce of gold sold for the Nechí Alluvial Property (Colombia) segment has been adjusted from amounts previously disclosed in historical MD&A to reflect this change. For greater certainty, this change does not affect AISC and AISC per ounce of gold sold of the Company on a consolidated basis, or for any other segment.

Cash Cost and All-in Sustaining Costs by Operating Segment

The following tables provide a reconciliation of Cash Cost per ounce of gold sold and AISC per ounce of gold sold by operating segment¹ to cost of sales, for the three months and years ended December 31, 2024, and 2023:

Three months ended December 31, 2024

Three months ended December 31, 2023

Year ended December 31, 2024

Three months ended December 31, 2023

1. The Gualcamayo Property was sold as part of the disposition of Minas Argentinas S.A. Results in the table in the column titled Gualcamayo (Discontinued operation) reflect results from January 1, 2023 to September 21, 2023 and solely pertain to the discontinued operation.

Reconciliation of Cash Cost per ounce of gold sold and AISC per ounce of gold - Nechí Alluvial Segment (Colombia)

The following tables provide a reconciliation of the calculation of Cash Cost per ounce of gold sold and the AISC per ounce of gold sold for the Nechí Alluvial Property (Colombia) segment for the three months and year ended December 31, 2023, reflecting changes made to the composition of those measures in the 2024 financial year and to align with the manner in which guidance is reported.

Cash Cost Reconciliation

AISC Reconciliation

Net Free Cash Flow

The Company uses the financial measure “net free cash flow”, which is a non-IFRS financial measure, to supplement information regarding cash flows generated by operating activities. The Company believes that in addition to IFRS financial measures, certain investors and analysts use this information to evaluate the Company’s performance with respect to its operating cash flow capacity to meet recurring outflows of cash.

Net free cash flow is calculated as cash flows generated by operating activities less non-discretionary sustaining capital expenditures and interest and dividends paid related to the relevant period. As the Gualcamayo Property was sold in September 2023, amounts related to the metrics shown in the following table have been calculated to reflect only the continuing operations of the Company.

The following table sets out the calculation of the Company’s net free cash flow to net cash flows generated by operating activities for the three months and years ended December 31, 2024, and 2023:

1. Composition of net free cash flow has been revised to exclude net cash flows used in (generated from) discontinued operations.

Return on Capital Employed (“ROCE”)

The Company uses ROCE as a measure of long-term operating performance to measure how effectively management utilizes the capital it is provided. This non-IFRS ratio is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The calculation of ROCE, expressed as a percentage, is Adjusted EBIT (calculated in the manner set out in the table below) divided by the average of the opening and closing capital employed for the 12 months preceding the period end. Capital employed for a period is calculated as total assets at the beginning of that period less total current liabilities.

Net Debt

Net Debt is a non-IFRS financial measure that provides insight regarding the liquidity position of the Company. The calculation of net debt shown below is calculated as nominal undiscounted debt including leases, less cash and cash equivalents. The following sets out the calculation of Net Debt as at December 31, 2024 and 2023.

Average Realized Price

The Company uses “average realized price per ounce of gold sold” and “average realized price per ounce of silver sold”, which are non-IFRS financial measures. Average realized metal price represents the revenue from the sale of the underlying metal as per the statement of operations, adjusted to reflect the effect of trading at the holding company level (parent company) on the sales of gold purchased from subsidiaries. Average realized prices are calculated as the revenue related to gold and silver sales divided by the number of ounces of metal sold. The following table sets out the reconciliation of average realized metal prices to sales of gold and sales of silver for the three months and years ended December 31, 2024 and 2023:

^{_________________
1} Average realized price per ounce of gold sold, Cash Cost per ounce of gold from continuing operations, AISC per ounce of gold sold from continuing operations, and net free cash flow are non-IFRS financial measures, and ROCE is a non-IFRS ratio, with no standardized meaning under IFRS, and therefore may not be comparable to similar measures presented by other issuers. For further information and detailed reconciliations to the most directly comparable IFRS measures, see “Non-IFRS and Other Financial Measures”.
