Mineros Reports Second Quarter 2024 Financial and Operating Results

(all dollar amounts - other than per share amounts - are expressed in thousands of US dollars unless otherwise stated)

Mineros S.A. (TSX:MSA, MINEROS:CB) ("Mineros" or the "Company") today reported its financial and operating results for the three and six months ended June 30, 2024. For further information, please see the Company's unaudited condensed interim financial statements and management's discussion and analysis posted on Mineros' website https://mineros.com.co/en/investors/financial-reports and filed under its Mineros' profile on www.sedarplus.com.

Andrés Restrepo, President and Chief Executive Officer of Mineros, commented: "The second quarter was good from both a financial and an operational perspective. Our revenues, gross profit and Adjusted EBITDA were all higher in the second quarter due to the high price of gold. Cash Cost and all-in sustaining costs were at the higher end of guidance for our operations due to the weakening of the US dollar against the Colombian peso and stronger gold prices resulting in the mineral bought from our artisanal mining partners being more expensive. Our gold production from Company-owned mines was modestly behind expectations in Colombia and in line with expectations in Nicaragua. Because we processed more artisanal material in Nicaragua we stockpiled material coming from our Panama and Pioneer underground mines for processing in the third quarter of 2024. At this time we are maintaining our cost and production guidance but will be closely monitoring certain cost inputs and production at our Nechí operation in order to alleviate the bottlenecks experienced in the second quarter of 2024."

On September 21, 2023, Mineros sold all of the outstanding share capital of Mineros' subsidiary, Minas Argentinas S.A., which holds a 100% interest in the Gualcamayo Property in Argentina, to Eris LLC. Accordingly, the financial and operating results of the Company herein are presented for continuing operations comprising the Hemco Property and the Nechí Alluvial Property and omit the discontinued operations comprising the Gualcamayo Property. Certain results set out below have been restated to reflect only the continuing operations of the Company by removing amounts pertaining to the discontinued operations from previous totals. These restatements are reflected in the first and second quarter 2023 results in order to more appropriately compare the results from the second quarter of 2024 with the second quarter of 2023 and the first six months of 2024 with the first six months of 2023.

CORPORATE HIGHLIGHTS FOR THE THREE AND SIX JUNE 30, 2024

• Produced 105,444 ounces of gold, 65,641 ounces from our Nicaraguan operations, up 1% from the first six months of 2023 and 39,803 from our Colombian operations, down a modest 7% from the same period in 2023.
• Produced 466,745 ounces of silver in the first six months of 2024, up 63% from the same period in 2023.

FINANCIAL AND OPERATING HIGHLIGHTS FOR THE SECOND QUARTER OF 2024

The following table summarizes quarterly financial highlights for the three and six months ended June 30, 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, all-in sustaining costs ("AISC") per ounce of gold sold from continuing operations, net free cash flow and Net Debt are non-IFRS financial measures, and return on cash employed ("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.
2. The Gualcamayo Property was sold in September of 2023 and, accordingly, certain amounts have been restated to reflect the continuing operations of the Company by removing amounts pertaining to the discontinued operations. This restatement is reflected in the first six months of 2023 in order to more appropriately compare the results period over period.

• Revenue increased by 14%: Revenue totaled $133,384 during the second quarter of 2024, compared with $116,623 in the second quarter of 2023, with sales of gold of $124,976 at an average realized price per ounce of gold sold from continuing operations of $2,327, during the second quarter of 2024 compared with sales of gold of $111,708 at an average realized price per ounce of gold sold from continuing operations of $1,964 in the second quarter of 2023. The increase in revenue in the second quarter of 2024 is mainly explained by an 18% increase in average realized price per ounce of gold sold from continuing operations and a 83% increase in sales of silver of $2,973, offset by a 6% decrease in ounces of gold sold;

• Cost of sales increased by 22% to $91,991 during the second quarter of 2024, compared with $75,596 in the second quarter of 2023. This increase was primarily due to: (i) the higher price of gold increasing the costs to purchase material from artisanal miners of $7,825; (ii) greater depreciation and amortization relating to our operations of $1,753; (iii) the 13% devaluation of the US dollar against the Colombian peso and higher prices across the Company's operations, created increased maintenance and materials cost of $2,266, and service and labour costs of $2,002 and $1,067 respectively;

• Gross Profit from continuing operations increased by 1% to $41,393 in the second quarter of 2024, compared with $41,027 in the second quarter of 2023, mainly due to higher revenue as explained above;

• Profit for the period from continuing operations down 17%, to $18,076 or $0.06 per share during the second quarter of 2024 compared with $21,695 or $0.07 per share during the second quarter of 2023. The decrease in profit was due mainly to higher costs to purchase material from artisanal miners, modestly fewer ounces of gold sold and higher costs due to the strong Colombian peso. Profit for the period was also impacted by higher foreign exchange differences of $2,607 and higher taxes of $7,731;

• Adjusted EBITDA¹ up 4%: Adjusted EBITDA was $49,647 during the second quarter of 2024 compared with $47,649 during the second quarter of 2023, mainly explained by higher revenue;

• Net cash flows generated by operating activities were down 76%, totaling $7,115 in the second quarter of 2024, compared with $30,154 in the second quarter of 2023, The Company's net free cash flow was negative $6,818 for the three months ended June 30, 2024 , down from $21,762 in the same period of 2023, due to the timing issues of the payment of income tax $20,361 in Colombia;

• Dividends paid up 43% - Dividends paid during the second quarter of 2024 were $7,473, compared with $5,213 in the same period of 2023, explained by the extraordinary dividend approved at the ordinary meeting of the General Shareholders' Assembly in March 2024;

• Cash Cost & AISC: Cash Cost per ounce of gold sold from continuing operations in the second quarter of 2024 was $1,304 and AISC per ounce of gold sold from continuing operations was $1,514, compared with Cash Cost per ounce of gold sold from continuing operations of $1,044 and AISC per ounce of gold sold from continuing operations of $1,225 for the second quarter of 2023. The 25% increase in Cash Cost per ounce of gold sold from continuing operations is mainly explained by the 22% increase in cost of sales, due to higher gold prices and the effects of the COP:US$ exchange rate, along with the 6% 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.¹

• Capital investments² up 46% to $16,662: during the second quarter of 2024 capital investments of $16,662 were made into existing mines, and exploration & growth projects, compared with $11,439 in the second quarter of 2023; the increase is explained by higher investments at the Hemco Property.

Financial Highlights for six months ended June 30, 2024

• Revenue increased by 15%: revenue totaled $247,532 during the six months ended June 30, 2024, compared with $215,492 in the six months ended June 30, 2023, with sales of gold of $231,938 at an average realized price per ounce of gold sold from continuing operations of $2,200 in the six months ended June 30, 2024, compared with sales of gold of $206,668 at an average realized price per ounce of gold sold from continuing operations of $1,923 in the six months ended June 30, 2023;

• Cost of sales increased by 20%, to $172,669 in the six months ended June 30, 2024, compared with $143,567 in the six months ended June 30, 2023; The increase in costs is primarily due to higher cost of purchasing artisanal material of $12,794 due to higher gold prices, higher labour costs of $3,818, higher services of $3,806 and higher taxes and royalties of $237;

• Gross Profit from continuing operations increased by 4%, amounting to $74,863 in the six months ended June 30, 2024, compared with $71,925 in the six months ended June 30, 2023; mainly due to an 15% increase in revenue, which was partially offset by a 20% increase in cost of sales as explained above;

• Profit for the period from continuing operations was down by 9% to $34,850 or $0.12 per share during the six months ended June 30, 2024 compared with $38,446 or $0.13 per share during the six months ended June 30, 2023; the decrease in profit is mainly explained by the modest increase in gross profit offset by an increase in costs. Profit was positively impacted by higher foreign exchange differences of $4,763. Profits were also impacted by lower other income of $2,598 due to the receipt of an insurance payment of $4,889 related to the overturning of the Llanuras Plant in the first quarter of 2023, higher deferred taxes of $8,653 and lower current taxes of $813;

• Adjusted EBITDA up 6%: Adjusted EBITDA was $90,301 during the six months ended June 30, 2024 compared with $85,403 during the six months ended June 30, 2023 due to a 15% increase in revenue, offset by a 20% increase in cost of sales and a 10% increase in administrative expenses;

• Loss for the period from discontinued operations decreased by 100%, to $0 during the six months ended June 30, 2024, compared with a loss of $10,490 during the six months ended June 30, 2023, due to the sale of the Gualcamayo Property;

• ROCE was 31% as at June 30, 2024 compared with ROCE of 27% as at June 30, 2023; the increase is mainly explained by 9% higher Adjusted EBITDA for the last 12 months, along with a 6% decrease 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 $1,898 as at June 30, 2024, compared with $(3,820) as at June 30, 2023; explained by 74% lower cash and cash equivalents, along with 50% lower loans and other borrowings;

• Dividends Paid up 26%: Dividends paid of $12,712 during the six months ended June 30, 2024, compared with $10,050 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 down 47% totaling $17,220 in the six months ended June 30, 2024, compared with $32,652 in the same period of 2023. The Company's net free cash flow was negative for the six months ended June 30, 2024 and totaled $8,715, down from $11,530 in the same period of 2023, due to timing issues of the payment of income tax of $22,517 in Colombia. While the sale of the Gualcamayo Property resulted in lower receipts from the sale of goods, commissions and other revenue, and various hedging instruments of $23,762, in total these decreases were more than offset by the reduction in payments to suppliers and employees, and social security agencies, among others, which totaled $30,802;

• Capital investments up 17% to $31,025: during the six months ended June 30, 2024 capital investments of $31,025 were made into existing mines, and exploration & growth projects, compared with $26,421 in the six months ended June 30, 2023. This increase is explained in part by higher exploration capital expenditures of $867 and no capital expenditures related to the Gualcamayo Property which were $7,687 in the comparative period, offset with an increase of $11,430 at the Hemco Property.

Operational Highlights by Material Property

(All numbers in ounces unless otherwise noted)

• Gold production decreased by 6%: Excluding the results of the discontinued operations at the Gualcamayo Property (disposed of in 2023), 53,703 ounces of gold were produced during the second quarter of 2024, compared with 56,864 ounces in the second quarter of 2023. The decrease in production is mainly a result of 16% lower than expected production at the Nechí Alluvial Property, explained by lower volumes and lower grades.

• Exploration and Evaluation Expenditures: for the three months ended June 30, 2024, the Company incurred $2,643 in exploration and evaluation ("E&E") expenditures, an increase of 38% compared with the second quarter of 2023. The increase is mainly explained by higher exploration expenditures which were capitalized in the Hemco Property, related to the Porvenir Project. The increase in exploration expenses is mainly due to higher regional exploration in the Hemco Property. The following table summarizes E&E expenditures for the current and comparative periods.

1. Capitalized E&E expenditures are reflected in E&E projects in the consolidated statements of financial position.
2. Figures in the table reflect expenditures capitalized from continuing operations. E&E expenditures capitalized from discontinued operations are nil.
3. Expensed E&E expenditures are reported in the consolidated statement of profit or loss for the respective period under "Exploration expenses".

GROWTH AND EXPLORATION PROJECT UPDATES

The two key growth and exploration projects the Company is advancing are the Porvenir Project and the Luna Roja Deposit, both located at the Hemco Property.

Porvenir Project, Nicaragua: 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.

Mineros updated the mineral resource model by incorporating all drilling data collected from the 2023 drilling campaign. The completed model is under review by SLR Consulting (Canada) Ltd., with ongoing updates to the geometallurgical assumptions.

The updates to the geometallurgical assumptions together with the analysis of the 2023 metallurgical testwork is underway, and the Company expects to receive the results in order to update the geometallurgical model in the second half of 2024.

In light of commodity market conditions management is proceeding logically and methodically to upgrade mineral resources and mineral reserves, and refine potential approaches to development described in the prefeasibility study completed on the Porvenir Project in 2023, with a view to maximizing the value of the asset and the projected returns. Accordingly, the Company has delayed preparation of the pre-feasibility study optimization to 2025.

Luna Roja Deposit, Nicaragua: 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.

Mineros anticipates finalizing technical work and analysis supporting an updated Mineral Resource estimate for the Luna Roja Deposit by the end of 2024 for publication in early 2025. The Company plans to select samples for metallurgical testing at the Hemco lab once the model is completed, which is expected in the fourth quarter of 2024.

The Company also plans to conduct fieldwork focused on geophysical anomalies starting in the fourth quarter of 2024.

OUTLOOK

The following section of this news release represents forward-looking information, and readers are cautioned that actual results may vary. We refer readers to the risks and assumptions contained in Section 14 - Cautionary Notes and Additional Information - Cautionary Statement on Forward-Looking Information in the Company's MD&A for the interim financial period ended June 30, 2024.

Gold production guidance

The following table presents the Company's gold production guidance for 2024 and actual production for the six months ended June 30, 2024. The production guidance includes production from the Company's Nechí Alluvial and Hemco Properties and from artisanal mining.

Given the operating results for the six months ended June 30, 2024, the Company maintains its production guidance for 2024.

Cost outlook

The following table outlines the Company's Cash Cost per ounce of gold sold and AISC per ounce of gold sold for the three months ended June 30, 2024, and cost guidance 2024. The cost guidance includes the Nechi Alluvial Property and the Hemco Property (the "Material Properties") and production from artisanal mining.

Cash Cost per ounce of gold sold and AISC per ounce of gold sold outlooks were prepared assuming an average selling price of gold of $1,980/oz and inflation of 10% in Colombia and 6% in Nicaragua. Cash Cost per ounce of gold sold has been trending at the high end of the guidance and given the strength of the Colombian peso and the strength of the gold price and its impact on our costs in Nicaragua we are monitoring this metric closely. We maintain our guidance at this time.

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. Certain amounts under each set of results have been restated to reflect continuing operations of the Company (amounts pertaining to discontinued operations of the Gualcamayo Property have been removed). The three and six months ended June 30, 2023 have been restated to this effect.

The following table sets out the calculation of EBIT, EBITDA and Adjusted EBITDA to Net profit for the three and six months ended June 30, 2024, and 2023:

1. For additional information regarding taxes, see Note 13 of our unaudited condensed interim consolidated financial statements, for the three and six months ended June 30, 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 and six months ended June 30, 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. Production 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. Certain amounts under each set of results have been restated to reflect continuing operations of the Company (amounts pertaining to discontinued operations of the Gualcamayo Property have been removed). The three and six months ended June 30, 2023 have been restated to this effect.

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 and six months ended June 30, 2024, and 2023:

1. Refers to cost of sales incurred in the Company's "Others" segment. See Note 7 of our unaudited condensed interim financial statements for the three and six months ended June 30, 2024 and 2023. The majority of this amount relates to the cost of sales of latex.

The following table provides a reconciliation of Cash Cost per ounce of gold sold on a by-product basis to cost of sales, before and after the change of definition of this metric, modified to capture cash outflows related to asset retirement obligation and environmental rehabilitation provisions, for the three and six months ended June 30, 2023:

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. Certain amounts under each set of results have been restated to reflect continuing operations of the Company (amounts pertaining to discontinued operations in Gualcamayo have been removed). The three and six months ended June 30, 2023 have been restated to this effect.

The following table provides a reconciliation of AISC per ounce of gold sold to cost of sales for the three and six months ended June 30, 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 unaudited condensed interim 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 unaudited condensed interim 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 unaudited condensed interim 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 and six months ended June 30, 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 unaudited condensed interim financial statements.

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. This restatement of net free cash flow is reflected in the three and six months ended June 30, 2023 in order to more appropriately compare the results period over period.

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 and six months ended June 30, 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

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. Certain amounts under each set of results have been restated to reflect continuing operations of the Company (amounts pertaining to discontinued operations in Gualcamayo have been removed). The three and six months ended June 30, 2023 have been restated to this effect. The following table sets out the calculation of ROCE as at June 30, 2024, and 2023.

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 June 30, 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 and six months ended June 30, 2024 and 2023:
