Strategic Highlights for the three months ended March 31, 2026

• Advanced the Company's strategy to strengthen its balance sheet exposure to physical gold, building a position of 31,623 ounces of gold-backed assets during the quarter, supporting the Company's longer-term treasury and capital allocation framework.
• Advanced the Porvenir Project with an updated Prefeasibility Study, delivering compelling base-case economics with an after-tax NPV (5%) of $460 million, an after-tax IRR of 37.9%, a 2.0-year payback, and an AISC of $1,295 per gold-equivalent ounce, with a gold assumption of $3,150/oz — positioning Porvenir as a high-margin cornerstone of an emerging polymetallic district at Hemco that also includes the Guillermina, Leticia, and San Antonio deposits.
• Entered into an agreement to acquire a gold exploration project in Tolima, Colombia, which, as reported by AngloGold Ashanti PLC in December 2024, hosts a historical mineral resource estimate of 23.35 million ounces of gold in the Indicated Mineral Resources category and 4.98 million ounces of gold in the Inferred Mineral Resources category.
• Advanced the Hemco expansion in Nicaragua, with sustained throughput reaching 2,000 tonnes per day (a 14.3% increase over the 1,750 tpd baseline). The Company is on schedule and within budget toward meeting interim milestones of 2,200 tpd by June 2026 and 2,500 tpd by December 2026.
• During the first quarter, the Company completed 12,770 metres (44 drill holes) of the 75,400 metres of diamond drilling planned. The drilling in the first quarter of 2026 represented a mix of in-mine drilling to expand the Mineral Resources and Mineral Reserves at the Panama and Pioneer Mines (5,311 metres in 19 holes) and 7,459 metres in 25 holes in greenfield and brownfield targets on our relatively underexplored land package in Nicaragua.
• Included in the S&P/TSX Global Mining Index, enhancing the Company's visibility among global mining investors and supporting broader institutional ownership of its TSX-listed shares.
• Achieved DTC eligibility, broadening U.S. investor access to the Company's shares on OTCQX and supporting enhanced share liquidity in U.S. markets.
• Recognized in the 2025 TSX30® Ranking and as a top performer on the Colombian Stock Exchange (BVC), reflecting sustained value creation for shareholders across both listing venues.

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.
