Daniel Henao, President and Chief Executive Officer of Mineros, commented: "Q1 2026 demonstrates the earnings leverage embedded in our growing production profile. With costs tracking below the lower end of guidance and production at the top end, we generated revenue of $292 million and net profit of $88 million; the strongest quarter in the Company's history. The Hemco expansion is advancing on schedule, gold and silver recoveries are improving, and the Porvenir prefeasibility study is delivering compelling economics. We are executing with discipline and are well positioned for the next phase of Mineros' growth."

"We also took deliberate steps this quarter to strengthen our balance sheet through an allocation to physical gold and gold-linked receivables, ending the period with gold-backed assets equivalent to 31,623 ounces of gold. This position is modest in scale, and reflects our view that gold remains an effective long-term store of value in the current macroeconomic environment. We regard it as a natural extension of our capital management framework, one that reinforces our identity as a gold producer and aligns our treasury with the interests of shareholders who invest in Mineros for exposure to the gold sector."

The following table summarizes the financial highlights for the three months ended March 31, 2026, and 2025.

Financial Highlights for the three months ended March 31, 2026

• Revenue increased by 82% and totaled $291,810 during the three months ended March 31, 2026, compared with $160,560 in the three months ended March 31, 2025. The increase in revenue is due to a 66% increase in the average realized price of gold sold, a 7% increase in ounces of gold sold and an increase in silver sales of 452%, partially offset by a decrease in energy sales of 11%. Gold sales totaled $276,360 at an average realized price per ounce of gold sold of $4,777 in the three months ended March 31, 2026, compared with sales of gold of $156,272 at an average realized price per ounce of gold sold of $2,881 in the three months ended March 31, 2025.
• Cost of sales increased by 55%, to $149,239 in the three months ended March 31, 2026, compared with $96,402 in the three months ended March 31, 2025. The increase in costs is primarily due to: (i) the higher cost of purchasing ore from BMP in Nicaragua of $31,934 and higher payments for services provided by Contract Mining Partners ("CMP") in Colombia of $3,068, both due to higher gold prices and more ounces purchased; (ii) higher taxes and royalties of $6,673 (iii) higher labour costs of $3,184; and (iv) greater maintenance and materials costs of $3,371, offset by lower costs for services like leases and energy of $1,698.
• Gross Profit increased by 122% to $142,571 in the three months ended March 31, 2026, compared with $64,158 in the three months ended March 31, 2025; due to a 82% increase in revenue, due to higher gold prices, which was partially offset by a 55% increase in cost of sales as explained above.
• Profit for the period was up by 131% to $87,686 or $0.29 per share during the three months ended March 31, 2026, compared with $38,007 or $0.13 per share during the three months ended March 31, 2025. The increase in profit is due to the increase in gross profit, partially offset by an unrealized loss of $3,330 on the forward contract entered into as part of the Company's strategic gold position (see "Strategic Gold Position" in Section 2), other expenses of $2,824 and an increase in administrative expenses of $311. In addition, as a result of the higher profit before taxes, current tax expenses increased by $20,016.
• Adjusted EBITDA was up 116% to $154,087 during the three months ended March 31, 2026, compared with $71,300 during the three months ended March 31, 2025, due to an 82% increase in revenue, offset by a 55% increase in cost of sales, and a decrease of $311 in administrative expenses.
• ROCE was 61% as at March 31, 2026, compared with 40% as at March 31, 2025. The increase is mainly attributable to 83% higher Adjusted EBITDA over the last 12 months, resulting from higher gold prices and production (an additional 9,468 ounces). Capital employed increased by 30%, reflecting higher capital expenditures in property, plant and equipment, the acquisition of 80% of the La Pepa Project, and the accumulation of gold-exposed assets under the Company's strategic gold position, which contributed to the increase in trade accounts receivable and inventories (see "Strategic Gold Position").
• Net cash was $8,020 as at March 31, 2026, compared with $53,163 as at March 31, 2025, reflecting lower cash and cash equivalents of $43,565 (down 46%) combined with 27% higher loans and other borrowings of $35,545. The reduction in cash and cash equivalents during the period primarily reflects the accumulation of gold-exposed assets under the Company's strategic gold position (see "Strategic Gold Position"). The balance sheet remains conservatively structured, providing financial flexibility to support ongoing investments and future growth initiatives.
• Dividends Paid were down 1% to $7,375 during the three months ended March 31, 2026, compared with $7,476 in the same period of 2025. The period over period decrease is due to the fact that there were fewer issued and outstanding shares than in the first quarter of 2025.
• Net cash flows used in operating activities totaled $59,636 in three months ended March 31, 2026, compared with net cash flows generated of $11,634 in the same period of 2025. The Company's net free cash flow for the three months ended March 31, 2026 totaled $(71,944) down from $(1,080) in the same period of 2025 The period-over-period change primarily reflects working capital movements associated with the Company's strategic gold position (see "Strategic Gold Position"), including an increase of $127,165 in trade accounts receivable related to gold sales positions pending final price determination and an increase of $23,037 related to the acquisition of physical gold bullion. These working capital movements are further explained by greater income tax payments of $18,063, and higher capital expenditures of $102 related to purchases of intangible assets and exploration expenditures, partially offset by higher receipts from sales of goods of $40,055.
• Capital investments were down 48% to $11,008 during the three months ended March 31, 2026, compared with $21,175 in the three months ended March 31, 2025. The decrease is due to an amendment of a vehicle leasing contract which cost the Company $5,793 at the Hemco Property in the first quarter of 2025, combined with a reduction of $3,419 in spending on the San Jose tailings expansion project.

2026 Guidance

For 2026, Mineros is providing consolidated gold production guidance of 213,000 to 233,000 ounces of gold. This represents an increase of 10,000 ounces relative to 2025 guidance. This increase is the result of a disciplined focus on "quick-return" ounces, prioritizing capital investment toward brownfield projects and operational efficiencies that can be brought online rapidly to maximize free cash flow in a robust commodity market.

2026 Operational & Cost Outlook

The Company's production and cost guidance reflects a commitment to maintaining healthy margins despite global inflationary pressures.

In 2026, the Hemco Property (Nicaragua) is expected to deliver solid performance with gold production guidance of 130,000-140,000 ounces. The Panama & Pioneer operations are expected to have an AISC range of $2,000-$2,100 per ounce. In addition, the Bonanza Mining Partners arrangement is expected to generate a 39%-41% AISC margin, providing a robust contribution to production.

For the Nechí Property (Colombia), Mineros is targeting steady gold output of 83,000-93,000 ounces in 2026. Company-owned dredges are expected to operate within an AISC range of $1,820-$1,920 per ounce, underpinned by continued focus on optimizing operations and controlling costs. The contract mining partners are expected to deliver an AISC margin of 11%-14%, representing consistent and dependable cash generation at this operation.

Capital Expenditures ("CAPEX"): Financing the Growth Horizon

The 2026 CAPEX budget is structured to balance sustaining requirements with high-impact growth initiatives.

Operational summary for the three months ended March 31, 2026

The following table sets forth the gold produced by each of the operations of the Company for the three months ended March 31, 2026, and 2025 with a discussion of the operational highlights for the same periods:

• Gold production increased by 7% to 57,850 ounces of gold during the first quarter of 2026, compared with 54,243 ounces in the first quarter of 2025, driven by 22% higher production at the Hemco Property offset by 14% lower production at the Nechí Property. On a gold equivalent basis production increased by 10% to 60,782 AuEq ounces, compared with 55,124 AuEq ounces in the first quarter of 2025, reflecting both higher gold output and strong silver recovery at the Hemco processing plant. At the Nechí Property in Colombia, first quarter production of 19,909 ounces reflects the variability characteristic of alluvial mining operations and is aligned with our planned operational sequence within our 2026 environmental, hydraulic, and mining plans. Nevertheless, the Company maintains its full-year production guidance of 83,000-93,000 ounces for the Nechí Property.
• Cash Cost & AISC: Cash Cost per ounce of gold sold in the first quarter of 2026 was $2,002 and AISC per ounce of gold sold was $2,235, both tracking below the Company's 2026 guidance ranges of $2,070-$2,170 per ounce for Cash Cost and $2,370-$2,470 per ounce for AISC. Compared with the first quarter of 2025, Cash Cost per ounce increased by 39% (from $1,437) and AISC per ounce increased by 33% (from $1,685), reflecting higher payments to Bonanza Mining Partners in Nicaragua driven by elevated gold prices and produced ounces, higher taxes in Nicaragua and a 13% US dollar devaluation in Colombia. Exhaustive cost-control measures were offset by the strength of the Colombian peso. As most costs are denominated in the local currency, its appreciation during the period resulted in an adverse impact on the Nechí Property cost structure. These cost pressures are consistent with the assumptions underpinning the Company's 2026 guidance.
• Exploration and Evaluation Expenditures ("E&E") for the three months ended March 31, 2026, the Company incurred $929 in capital expenditures, a decrease of 10% compared with the first quarter of 2025, the decrease is associated with reduced drilling activities during the first quarter of 2026 compared with the same period offset by higher E&E at Nechí Property.

Health and Safety

Heading into 2026, Mineros reaffirms its commitment to provide a safe and healthy workplace where employees and contractors conduct themselves in a responsible and safe manner. Additionally, the Company is committed to achieving a high standard of Occupational Health and Safety practices by evolving our management systems and rigorously monitoring performance targets. This commitment to excellence is validated by our ISO 45001 certifications at both the Nechí Property and Hemco properties.

The following table presents the safety statistics for the three months ended March 31, 2026, and the same period 2025.

At the Nechí Property, the LTIFR increased to 0.96 from 0.62 in Q1 2025. The Company has reviewed the underlying events and is implementing corrective actions as part of its continuous safety improvement program. The TRIFR improved from 3.10 to 1.93, reflecting the effectiveness of Mineros' broader safety management system. The Company remains committed to its zero-harm objective and to the ongoing evolution of its ISO 45001-certified occupational health and safety practices.

The Colombia Operation continues to strengthen its preventive safety management through the implementation of Leading Indicators. Visible HSE leadership has intensified cross-inspections in critical tasks and proactive reporting of substandard acts and conditions across all operational areas. These actions, combined with enhanced technical competency development in occupational health and safety and rigorous critical risk management, have been instrumental in driving the favorable safety trend reflected in the reduction of the 38% from Total Recordable Incident Frequency Rate (TRIFR).

Mineros has integrated a number of mining operators who are in the process of formalizing their operations to comply with Colombian regulations with Mineros' assistance. Mineros' current safety performance metrics do not yet include CMP, as they are still in the process of adopting our Company's safety standards. The Company is actively working to support these operators with training focused on helping them meet safety requirements including training on the proper use of personal protective equipment, and adoption of risk mitigation and prevention techniques.

Additionally, the miners associated with the Bonanza Partnership Model are not yet included within the scope of the metrics presented in this report. The Company, through the Municipal Artisanal Mining Commission (CMMA), the model's governing body, is currently strengthening the systematization, accounting, and monitoring mechanisms for accident statistics regarding this stakeholder group. Furthermore, it is enhancing cultural adoption and change management processes to ensure these figures reach the level of maturity required for integration into the consolidated statistics.

GROWTH AND EXPLORATION PROJECT UPDATES

The Company's exploration and growth is focused on the replacement and expansion of Mineral Resources and Mineral Reserves by completing further work at or near our operating mines, at our growth projects and at early-stage exploration targets on our under-explored property interests. We are achieving our goals through systematic exploration programs, which include surface mapping and sampling, geochemical data collection surveys, geophysical surveys and drilling.

A core component of the business strategy of the Company is to explore new targets and develop existing deposits at or near the operating mines, with the objective of increasing Mineral Resources and Mineral Reserves and advancing promising deposits towards development.

The Company continues reviewing exploration targets at the Hemco property and analyzing its near-term potential, Porvenir deposit which is the most advanced target will remain under review, analysis and designing through the year. Two potential growth and exploration projects the Company is reviewing are the Porvenir Project and the Luna Roja Deposit, both located at the Hemco Property.

The current estimate includes both open pit and underground components and reflects revised economic assumptions and updated geological interpretation.

Although drilling was not contemplated in the original 2026 exploration plan, the Company is currently reassessing the exploration strategy for Luna Roja as of the first quarter of 2026.

Following the year-end closing analysis performed in December 2025, management concludes that there is no asset impairment and in compliance with the request of the Nicaraguan Ministry of Energy and Mines. The Company will continue to assess mineral potential including its respective project phases and a schedule for each stage. While we are managing the necessary administrative steps to ensure project viability, these processes introduce uncertainty regarding the timing and approval of future operational permits.

Hemco Property Regional Exploration

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

In 2026, greenfield exploration activities will be focused over the three priority districts:

• Bonanza District: This district hosts targets characterized by gold-silver-zinc mineralization, as evidenced by historical mining, artisanal workings, and surface sampling.
• Rosita District: This district comprises targets with predominantly gold-silver mineralization identified from historical mining records, artisanal workings, surface sampling, and limited scout drilling.
• Siuna District: This district includes targets with demonstrated gold-silver mineralization identified through historical mining, artisanal activities, and surface sampling.

Regional greenfield exploration activities commenced in late March 2026, reflecting the prioritization of near-mine and brownfield drilling using Mineros' owned rigs, as well as delays starting the drilling contracts, which are expected to be finalized by the second quarter of 2026. Although this campaign was originally designed to be executed using contractors, the delays related to the drilling contract resulted in the initial drilling being carried out with the Company's owned rigs.

During the first quarter, the Company completed 947 metres of diamond drilling across four holes, representing approximately 4% of the planned drilling program for the year. Drilling activities were initiated at the Experiencia target, recently renamed Apoyo, which is located within the Bonanza district.

Nechí Property, Colombia

Near Mine Exploration, Nechí Property Expansion

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

As of the first quarter of 2026, drilling activities had not yet commenced due to several factors, including unexpected changes in the minimum wage by government decree and public order events that resulted in fluvial and road blockades affecting logistics, personnel rotation, and supply chains across the Company's operating area. The Company expects to initiate the program in the second quarter of 2026.

La Pepa Property, Chile

The La Pepa Project is an advanced gold exploration project, 100% owned by Mineros, located in the Maricunga Gold Belt of the Atacama Region, Chile, approximately 800 km north of Santiago and 110 km east of Copiapó, at 4,200 metres above sea level in the Andes Mountains.

Mineros has planned a 7,000-metre exploration program at La Pepa project. As of the first quarter of 2026, drilling activities have not yet commenced, as planed. The Company has applied for a sectorial permitting while working on the environmental characterization studies to support future Declaration of Environmental Impact (DIA) requirements.

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 ended March 31, 2026 and 2025:

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 ended March 31, 2026, and 2025.

All-in Sustaining Costs

The objective of AISC is to provide stakeholders with a key indicator that reflects as closely 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 ended March 31, 2026, and 2025.

Cash Cost and All-in Sustaining Costs by Operating Segment

The following table provides 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 ended March 31, 2026, and 2025.

Margin CMP & BMP

The margin between the All-In Sustaining Cost (AISC) of each operation and the average price of gold sold is a key indicator of operational profitability and financial health for a gold mining company. AISC represents the comprehensive cost to produce one ounce of gold, including direct mining costs, sustaining capital expenditures, corporate overhead, and other ongoing expenses necessary to maintain current production levels. By comparing the AISC of each operation to the average realized gold price during the reporting period, we can assess the profitability of each mine and the company as a whole.

Gold equivalent ("AuEq")(oz)

The Company calculates gold equivalent ounces to provide a measure that reflects the aggregate economic potential of the assets in question. The methodology employed for the calculation of equivalent ounces is as follows: Gold ounces produced and revenue derived from silver ounces sold is divided by the average realized price per ounce of gold sold. This approach captures the value contributed by both gold and silver production, thereby enabling a comprehensive evaluation of the asset's overall economic viability.

The formula utilized for this calculation is expressed as:

Gold equivalent ("AuEq") ounces = Gold ounces produced + (revenue derived from silver ounces sold) / average realized price per ounce of gold sold.

The following table provides a reconciliation of Gold equivalent by operating segment² to cost of sales, for the three months ended March 31, 2026, and 2025.

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.

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 ended March 31, 2026, and 2025:

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 March 31, 2026 and 2025.

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 gold 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 ended March 31, 2026 and 2025:
