• Increased production: In the second quarter of 2025, gold production was 42,587 ounces, representing a 20% increase over the prior quarter.
• Record free cash flow generation: $60.2 million of free cash flow ⁽²⁾ and $79.8 million of cash provided by operating activities were generated in the second quarter. The Corporation expects strong ongoing free cash flow ⁽²⁾ at current gold prices through the remainder of 2025.
• Generating robust margins: Reported all-in sustaining cost ⁽²⁾ ("AISC") per ounce of gold sold of $1,170, compared to an average realized gold price ⁽²⁾ of $3,014 per ounce year to date.
• Record quarterly revenue of $129.6 million, representing a 32% increase over the prior quarter.
• Record adjusted EBITDA (Earnings before Interest, Taxes, Depreciation and Amortization) ⁽²⁾ of $92.9 million during the quarter and $161.0 million year to date.
• Strong profitability: Reported net income of $48.6 million, or $0.21 per share, and $73.1 million, or $0.32 per share year to date.
• Strong liquidity: Cash balance was $156.1 million at the end of the second quarter, an increase of $7 million over the prior quarter.
• Advancing Oko West: Early works activities continue to progress rapidly with $63 million of development capital spent year to date. Detailed engineering is 19% complete, with approximately $190 million committed.

Recent Corporate Highlights

• Achieved nameplate capacity at the Tocantinzinho ("TZ") processing plant operating at 96% of designed throughput of 12,890 tonnes per day during May and June.
• Received a court ruling (State) that removes a longstanding regulatory constraint on the Gurupi Project in Brazil, providing GMIN with the green light to advance the project with clarity.
• Published GMIN's third annual environmental, social and governance ("ESG") report.

"Q2 was a pivotal quarter for GMIN, as we achieved nameplate throughput at TZ and delivered a step-change in gold production and free cash flow," said Louis-Pierre Gignac, President & Chief Executive Officer. "With strong operating performance and disciplined cost management, we generated over $60 million in free cash flow ⁽²⁾, strengthening our balance sheet and enabling us to advance our high-potential growth pipeline. The completion of the Oko West Feasibility Study and immanent receipt of the Final Environmental Permit, along with resolution of legacy permitting issues at Gurupi provide clear visibility on our next phases of development. These results reflect the strength of both our team and our strategy to build GMIN into the next multi-asset, mid-tier gold producer."

Financial Results ⁽¹⁾:

Financial Highlights

Gold sales totaled 40,082 ounces, generating $129.6 million in revenue at an average realized gold price⁽²⁾ of $3,233 per ounce — benefiting from both higher production and stronger gold prices compared to Q1 2025.

Cash costs ⁽²⁾ were $763 per ounce, while AISC ⁽²⁾ totaled $1,355 per ounce, largely driven by the timing of sustaining capital expenditures, including non-recurring mobile fleet purchases. As these one-time investments are now complete, the Corporation anticipates AISC will decline in the second half of the year.

Cash flow from operations totaled $79.8 million, resulting in free cash flow ⁽²⁾ of $60.2 million ($0.27 per share) and a cash balance of $156.1 million at quarter-end.

Adjusted EBITDA ⁽²⁾ totaled $92.9 million, reflecting the combination of higher gold sales and continued cost discipline.

Adjusted net income ⁽²⁾ was $36.5 million ($0.16 per share).

The Corporation ended the quarter with $156.1 million in cash and equivalents, up from $149.0 million in Q1. This increase reflects strong free cash flow ⁽²⁾ generation, partially offset by continued investment in Oko West, exploration activities and working capital.

This robust liquidity position provides the Corporation with the flexibility to fund ongoing development at Oko West and Gurupi without requiring near-term external capital.

TZ – Q2 2025 Operating Summary

The second quarter marked a key milestone in the ramp-up of TZ Gold Mine. In June, the plant achieved nameplate throughput, averaging 12,890 tonnes per day over a 30-day period, following the installation of new steel liners in the semi-autogenous grinding mill. This upgrade has resulted in improved equipment availability and metallurgical performance.

• Gold production of 42,587 ounces represents approximately 23% of full-year midpoint guidance of 187,500 ounces.
• Average plant throughput for the quarter was 11,107 tpd, or 86% of nameplate capacity, compared to 78% in Q1.
• Gold recovery raised to 90.3%, compared to 87.7% in Q1, supported by improved plant stability and efficient operation assisted by the expert control system.
• Processed grade averaged 1.45 g/t Au, in line with the mine plan.
• Mining rate increased to approximately 4.4 million tonnes, including 1.6 million tonnes of ore, resulting in a strip ratio of 1.64x.
• Ore stockpiles at quarter-end totaled 6.0 million tonnes at 0.77 g/t Au, providing flexibility for blending and mill feed optimization in H2 2025.

TZ – Sustaining Capital

Q2 2025 sustaining capital totaled $18.6 million, primarily for additions to the mobile fleet, tailings management, and mill optimization. Full-year sustaining capital remains forecast between $60–70 million, with $36–46 million expected in H2, ~40% of which is allocated to capitalized stripping as TZ transitions to steady-state operations.

Now entering steady-state operations, TZ will focus on maintaining throughput, improving recovery, and lowering unit costs.

Oko West Development Update

In April 2025, GMIN published the results of the Feasibility Study for Oko West, outlining a long-life, low-cost, and high-margin operation. Key highlights include:

• Average annual production of 350,000 ounces over a 12.3-year mine life
• AISC of $1,123 per ounce and initial capital cost of $972 million
• Base case after-tax NPV₅% of $2.2 billion and IRR of 27% at a gold price of $2,500 per ounce
• Upside case after-tax NPV₅% of $3.2 billion and IRR of 35% at a gold price of $3,000 per ounce

Early works construction commenced in March and is progressing on schedule, including road access, camp construction, and a wharf facility. With substantial completion targeted by year-end, these activities will position the project to move confidently into full construction in the coming year.

Environmental permitting advanced during the quarter. Following the submission of the full Environmental and Social Impact Assessment ("ESIA") to Guyana's Environmental Protection Agency ("EPA") in late May, the EPA has now approved the ESIA, and we are imminently awaiting the grant of the Full Environment Permit, marking a key regulatory milestone for construction readiness.

Exploration activities at Oko West continued during the quarter, with drilling focused on near-pit extensions based on a new interpretation of the mineralized zone known as the "splay model." Trenching and mapping also progressed along the main shear zone south of the pit. The Corporation's 2025 exploration strategy remains focused on expanding mineral resources along the shear zone and identifying additional targets across the broader land package.

Gurupi – Regulatory Clarity and Path Forward

In July 2025, the Corporation announced a favourable decision by the Federal Court of Maranhão in Brazil, confirming its right to restart the permitting process for the Gurupi Project under its current ownership. This ruling invalidated outdated licenses issued to prior operators and cleared the way for GMIN to pursue new environmental and mining permits.

Following this legal resolution, the Corporation is progressing toward the receipt of exploration permits to restart drilling activities. In parallel, new baseline environmental and social studies will be initiated, and early engagement has begun with local communities and stakeholders.

The Gurupi Project, located in Maranhão State, Brazil, hosts 1.83 million ounces of indicated and 0.77 million ounces of inferred mineral resources across a large and prospective land package. The Corporation is reviewing historical exploration data and assessing future drilling opportunities to evaluate potential resource expansion and further validate the geological model. In light of recent positive developments, an additional $4 million budget has been allocated to launch an inaugural drill program in the second half of the year.

ESG Highlights

On July 30, 2025 GMIN published its 2024 ESG Report, outlining key achievements and future targets:

• Total Recordable Injury Frequency Rate (TRIFR) of 0.08 over 2.5 million hours worked
• 94% of process water recycled; 74% of solid waste reused
• 33 hectares reforested and over 10,000 plants and animals monitored
• More than R$174 million (US$32 million) spent with local suppliers in 2024

In H2 2025, the Corporation will expand reforestation efforts and enhance stakeholder engagement programs across its portfolio.

Liquidity and Capital Resources

The Corporation ended Q2 2025 with a cash and cash equivalents balance of $156.1 million, compared to $149.0 million at the end of Q1 2025, reflecting continued strong free cash flow generation and disciplined capital deployment.

The $7 million increase in cash, quarter over quarter is primarily attributed to the following:

• Free cash flow ⁽²⁾ totaled $60 million, driven by higher gold sales and improved operational performance at the TZ Mine
• Non-sustaining investments ⁽²⁾ of $51 million, largely directed toward the continued development of the Oko West Project, including early works and long-lead equipment purchases and
• Net financing outflows, investments in long term inventories and foreign exchange adjustments of approximately $2 million

This strong cash position supports the Corporation's self-funded growth strategy and provides financial flexibility to continue advancing both Oko West and Gurupi without the need for immediate external capital.

2025 Outlook

GMIN reaffirms its full-year 2025 production guidance of 175,000 to 200,000 ounces of gold with an expectation of being at the lower end of guidance. As planned, production is weighted toward the second half of the year, reflecting improved throughput and recoveries as the TZ Mine transitions to steady-state operations. During the first half of the year, TZ produced 78,165 ounces, 45% of the lower end of our annual guidance range.

Cost guidance is increased by $30 per ounce to reflect the impact of State of Pará enacted legislation increasing the Tax for Control, Monitoring, and Oversight of Mining Activities ("TRFM"), effective March 27, 2025, and subsequently revised on May 21, 2025, through Decree No. 4,677.  The AISC guidance is therefore adjusted at $1,025 to $1,155 per ounce sold.

The Corporation also maintains its full-year capital and cost guidance with an increased exploration budget for Gurupi, as summarized below:

The Corporation remains focused on operational excellence, disciplined capital deployment, and delivering long-term value through its self-funded growth strategy. Development milestones at Oko West and Gurupi remain on track.

2025 Catalysts

In the second half of 2025, the Corporation expects to:

• Finalize project financing and make a construction decision for Oko West (H2 2025)
• Advance detailed engineering and continue early works activities at Oko West (2025)
• Continue environmental permitting activities at both Oko West (Q3 2025) and Gurupi
• Progress exploration initiatives-both greenfield and brownfield-across TZ, Oko West and Gurupi
