BROSSARD, Quebec, Aug. 12, 2026 (GLOBE NEWSWIRE) -- G Mining Ventures Corp. (“GMIN” or the “Corporation”) (TSX: GMIN, OTCQX: GMINF) today reported its financial and operating results for the second quarter ended June 30, 2026. Unless otherwise indicated, all dollar amounts are in U.S. dollars.

Louis-Pierre Gignac, President and Chief Executive Officer, commented: "We delivered another strong quarter, with better-than-planned production and disciplined cost control driving robust margins and solid quarterly free cash flow⁽¹⁾”. We remain on track to achieve full-year production guidance of 160,000 to 190,000 ounces of gold, with production expected to increase significantly in the second half of the year as we gain access to higher-grade phase 2 mineralization.

Our project pipeline continues to advance rapidly. At Oko, construction continues to advance on schedule and on budget, keeping us firmly on the path toward first gold pour in the second half of 2027, and Gurupi's development roadmap continues to take shape. The acquisition of G2 Goldfields Inc. (“G2”) consolidates the Oko district into a globally significant tier-one gold mining complex in a world class geological district.

Second Quarter 2026 Highlights

Continued strong safety performance: GMIN recorded zero Lost Time Injuries across TZ, Oko and Gurupi during the quarter, maintaining a Total Recordable Injury Frequency Rate (“TRIFR”) of 0.00 for the quarter and 0.07 for the six months ended June 30, 2026.
Solid operational quarter driven by strong execution and cost control: Tocantinzinho (“TZ”) delivered gold production of 36,845 ounces in the second quarter, a 16% increase over the first quarter of 2026 as mining sequencing continued to advance toward higher-grade Phase 2 mineralization. Total cash costs⁽¹⁾ of $1,046 per ounce sold were 1% higher than the first quarter, and All-In Sustaining Costs (“AISC”)⁽¹⁾ of $1,690 per ounce sold were 6% higher than the first quarter, largely driven by the stronger Brazilian real relative to the U.S. dollar. Second quarter gold sales totaled 37,439 ounce, an 11% increase over the first quarter of 2026 at an average realized price of $4,197 per ounce, generating quarterly revenues of $157.1 million.
Strong quarterly free cash flow⁽¹⁾ generation: Solid operational performance together with continued strength in the gold price has translated into strong financial performance. The Corporation reported quarterly net income of $72.0 million or $0.30 per basic share and adjusted net income⁽¹⁾ of $79.1 million or $0.33 per basic share. Cash provided by operating activities totaled $103.8 million, or $0.44 per basic share, while free cash flow⁽¹⁾ reached $84.8 million, equivalent to $2,301 per ounce produced, or $0.36 per basic share.
Continued investment: Capital expenditures totaled $158.5 million in the second quarter of 2026, comprising $10.6 million of sustaining capital, $8.3 million of capitalized stripping, $8.3 million of capitalized exploration expenditures and $131.3 million related to development activities at the Oko West Project (“Oko”).
Strong Balance Sheet maintained through heavy growth capital expenditures: At June 30, 2026, cash and cash equivalents totaled $225.7 million and long-term debt was $33.0 million, resulting in a net cash position of $192.7 million.

Gold Production and Gold Sales
During Q2 2026, the Corporation sold 37,439 ounces of gold, consisting of 32,673 ounces sold into the spot market and 4,766 ounces delivered into the gold stream. Gold production in the second quarter was higher than planned, driven by a higher-grade sequence and stable mill performance. Gold recoveries in the mill improved to 91.9% in the quarter, up from 90.3% in Q1 2026. Plant feed grades averaged 1.23 grams per tonne (g/t) gold during the quarter, up from 1.03 g/t in Q1 2026

For the first six months of 2026, total gold sales were 71,215 ounces, comprised of 61,214 ounces sold into the spot market and 10,001 ounces delivered into the gold stream. Gold production in 2026 was in line with the planned processing of lower-grade ore in the first half of the year as mining focused on accelerated waste stripping and pit advancement to access higher-grade Phase 2 mineralization.

TZ achieved record quarterly mining of 6.3 million tonnes (Mt) in Q2 2026, a 15% increase over Q1 2026. The planned commissioning of additional haul trucks and a front-end loader in Q3 2026 is expected to further support increased mining rates. Mining activities remain closely aligned with the mine plan, enabling access to higher-grade Phase 2 mineralization and positioning the operation for a significant increase in grade and production during the second half of 2026 allowing for substantially lower costs, consistent with guidance. Stockpile rehandling and blending continued to support stable and consistent plant feed throughout the quarter.

Cost Performance
Cash costs ⁽¹⁾ per ounce sold in the second quarter of 2026 was 37% higher when compared to the prior-year period due primarily to lower production volumes, higher royalties, and a stronger Brazilian real relative to the U.S. dollar.

AISC ⁽¹⁾ per ounce in the second quarter of 2026 was 25% higher when compared to the prior-year period due to the reasons described above for the increase in total cash costs and higher general and administrative expenses.

The Corporation reported an AISC ⁽¹⁾ margin of $2,330 per ounce of gold sold in the period, compared to $1,637 per ounce of gold sold in Q2 2025. Margins remained strong in the quarter, supported by the robust gold price environment and the Corporation’s low-cost operating profile. The low AISC ⁽¹⁾ reflects, among other factors, the benefit of TZ’s low strip ratio, the comparatively low diesel consumption associated with TZ’s hauling activities, as well as the fact that the processing facility is entirely energized by Brazil’s low-cost renewable hydro-electric power. As a result, the Corporation has relatively low exposure to diesel price volatility, with a $10 per barrel change to the oil price estimated to have a $8 to $10 per ounce impact on AISC, depending on the movement of materials.

Cash Provided by Operating Activities

Cash provided by operating activities totaled $103.8 million in the second quarter of 2026, compared to $79.8 million in the second quarter of 2025. The cash inflows were higher in 2026 mainly due to the higher gold price compared to the same period last year partially offset by lower ounces of gold sold and higher operating costs due to lower grade processed.

For the first six months of 2026, cash provided by operating activities totaled $173.5 million, compared to $110.3 million for the six months ended June 30, 2025. The cash inflows were higher in 2026 mainly due to the higher gold price compared to the same period last year partially by lower ounces of gold sold; higher operating costs due to lower grade processed and current income taxes paid for the year 2025.

Free Cash Flow⁽¹⁾
Free cash flow⁽¹⁾ in the second quarter of 2026 increased over both the first quarter of 2026 and the prior-year period, primarily for the reasons described above related to cash provided by operating activities. The Corporation generated quarterly free cash flow⁽¹⁾ of $84.8 million, or $0.36 per share, highlighting the asset's strong margin profile and ability to fund growth internally. For the first six months of 2026, free cash flow⁽¹⁾ was $140.9 million, or $0.60 per share.

Capital Expenditures
Capital expenditures totalled $158.5 million in the second quarter of 2026, comprising of $10.6 million of sustaining capital, $8.3 million of capitalized waste stripping, $8.3 million of capitalized exploration expenditures and $131.3 million related to development activities at Oko.

For the first six months of 2026, capital expenditures totalled $266.2 million, comprising of $12.9 million of sustaining capital, $18.9 million of capitalized waste stripping, $0.8 million of sustaining exploration, $13.8 million of capitalized exploration expenditures and $219.8 million related to development activities at Oko.

2026 & 2027 Outlook

Gold production of 68,691 ounces of gold for the first six months of 2026 was in line with the planned processing of lower-grade ore in the first half of the year as mining activities focused on accelerated waste stripping and pit advancement to access high-grade Phase 2 mineralization. The Corporation maintains its 2026 production guidance of 160,000 to 190,000 ounces, with approximately 61% of output expected in the second half of 2026 as higher-grade material is accessed in accordance with the mine plan. Higher production and lower unit costs are expected to drive stronger free cash flow⁽¹⁾ through the remainder of the year.

Cash Costs⁽¹⁾ and AISC⁽¹⁾ guidance for the full year 2026 have been revised to $836–$965 and $1,330–$1,544 per ounce sold, respectively, up from previous guidance of $736–$865 and $1,230–$1,444 per ounce sold, respectively.

The increase in Cash Costs⁽¹⁾ and AISC⁽¹⁾ guidance reflects several factors, including: the continued strength of the Brazilian real (BRL:USD assumption of 5.15, versus 5.55 previously); labor cost inflation in Brazil; continued investment in maintenance; and higher assumed gold prices, which increase royalty costs ($4,300/oz, versus $4,000/oz previously).

Total capital expenditures guidance for 2026 (excluding capitalized exploration) remains unchanged at $583 to $649 million, comprising of $38 to $45 million sustaining capital expenditures, $31 to $36 million of capitalized waste stripping and $514 to $568 million related to development activities at Oko. Capital exploration guidance for 2026 remains unchanged at $42 to $50 million.

Full year guidance for 2027 for production, costs and capital expenditures remains unchanged.

Advancing the Next Phase of Transformational Growth

Oko – More than 2.3 million person-hours have been worked at Oko, with over 1,700 employees and contractors currently on site, 77% of whom are Guyanese nationals. As of June 30, 2026, overall project progress at Oko had reached 28.0% based on earned value, with construction advancing on schedule across key work areas, including the process plant, power plant, tailings storage facility and site infrastructure.

As of June 30, 2026, $423 million had been spent on the Project, representing 44% of the approved initial capital budget of approximately $973 million, with approximately $550 million remaining to be spent through completion. Total commitments reached approximately $628 million, or 65% of the approved budget. 2026 represents the peak construction year, with expected project spending of $514 to $568 million, of which $219 million was spent during the first half of the year.

Detailed engineering is approximately 90% complete and is expected to conclude in the third quarter of 2026, while procurement had reached approximately 99% completion as of the end of June 2026. Key achievements in the process plant area during the quarter included continued concrete pours across the power plant, SAG and ball mill foundations, primary crusher, CIL/CIP tanks and pre-leach thickener. Other key infrastructure workstreams also advanced, including the permanent camp, which now has more than 1,400 beds available, with the welcome centre, kitchen and dining hall operational.

Construction remains on schedule, with first gold pour targeted for the second half of 2027 and commercial production expected in early 2028.

G2 Transaction Completed – The completion of the G2 acquisition creates a tier-one gold asset with potential to deliver substantially increased average annual gold production over the life of mine (LOM) once the expansion is completed, further elevating GMIN's industry-leading near-term growth profile (see GMIN news release dated July 29, 2026). The Corporation will launch an integration program aimed at advancing the Oko-Ghanie deposits through infill drilling to support an integrated mineral resource estimate (“MRE”) and an updated feasibility (“FS”) for an expanded Oko Gold Project. Complementary technical programs, including metallurgical, geotechnical, and other engineering studies, will also commence in the second half of the year to support the integrated project development.

Oko Construction Progress - Below are photos highlighting recent construction progress at Oko:

The power plant continues to advance with over 1,350 m³ of concrete poured to date and the structural steel framing for the engine hall complete. Day tank and stack foundations are also complete while cable tray and electrical are currently being installed. Fuel treatment building (right) has completed framing.

The SAG mill foundation is completed with anchor bolts and embedded plates. The first concrete pour for the ball mill foundation will take place in August.

The permanent camp has over 1,400 beds, with the welcome centre, kitchen & dining hall all operational and open to employees.

The primary crusher has advanced significantly with the mat foundation concrete pour completed. The rebar and concrete pours of the first level will commence in August.

Excavation has been completed for five CIL tanks, with construction of two inner rings advancing. Foundations for all seven CIP tanks have been completed, with tank installation scheduled to commence in August. The photo also shows the commencement of the pipe rack structure.

Construction of exterior rings two and three on our pre-leach thickener are more than halfway complete while ring four is being prepared to be poured in August. This work is in tandem with the associated piers.

Gurupi’s Development Roadmap Taking Shape - GMIN plans to invest between $19 million and $23 million in exploration in 2026 to grow the resource base through both brownfield and greenfield programs, with the goal of delivering an MRE and a preliminary economic assessment (“PEA”) in the second half of 2026. Alongside the exploration program, environmental and social baseline studies are advancing in support of an Environmental and Social Impact Assessment (“ESIA”) submission targeted for the fourth quarter of 2026.

Second Quarter 2026 Exploration Activities

During the second quarter of 2026, the Corporation advanced exploration across its three key properties, with first-half expenditures totaling $13.8 million ($2.6 million at TZ, $4.8 million at Oko, and $6.4 million at Gurupi), and full-year guidance maintained as activity is set to accelerate following the closing of the G2 transaction. At TZ, drilling tested depth extensions within the pit and advanced regional targets along the main structural trend, including Toca-Toca, North Airstrip, Arara Azul, and the newly initiated Santa Patricia target, reinforcing a strategy centered on mine life extension.

At Oko, drilling focused on the Lukanani target with nearly 9,900 metres completed, while the Corporation prepares to launch an integration program combining infill drilling and technical studies to support an updated feasibility study for an expanded, integrated Oko-Ghanie project.

At Gurupi, five drill rigs tested the northern extension of the Chega Tudo deposit and advanced the Grodiacol, Mandiocal, and Cipoeiro targets, supported by extensive soil sampling and trenching, with results expected to feed into resource growth and a year-end PEA.

With pending assay results expected shortly, the Corporation anticipates providing an exploration update highlighting significant results during the third quarter of 2026.

Environmental, Social & Governance (ESG)

Key ESG accomplishments during the quarter included the publication of the 2025 Sustainability Report, continued implementation of its health, safety, environment, and community management platform, advancement of corporate Environmental and Social Performance Standards, and the development of action plans associated with human rights, security, tailings management, and operational assurance programs. From the permitting perspective, TZ achieved important milestones during the quarter. The Installation License for the Tailings Storage Facility ("TSF") raise to elevation 161 was issued in June 2026 and this represents 2 more years of tailing disposal at the TSF.

During the quarter, the Corporation continued developing its Environmental and Social Performance Standards, which will establish minimum operational requirements across all assets and create a consistent framework for environmental management, social performance, community relations, human rights, and governance practices. Completion of these standards are targeted for H2 2026 and is expected to further strengthen accountability and performance consistency across the portfolio.

GMIN also made significant progress strengthening operational management systems, which is expected to standardize incident management, inspections, corrective actions, and performance reporting while providing enhanced visibility and governance oversight across all operations.

Overall, the Corporation’s ESG activities during 2026 remain focused on strengthening governance systems like the achievement of 71% alignments with TSM for TZ, improving transparency, enhancing operational assurance, and embedding consistent environmental and social management practices capable of supporting long-term growth across multiple assets and jurisdictions.

There can be no assurance that, notably but without limitation, (i) the G2 acquisition will transform Oko into a globally significant Tier-One gold asset; (ii) GMIN’s integration program for G2’s Oko-Ghanie will meet expectations; (iii) TZ will continue operating at steady state, enabling it to improve productivity; (iv) TZ will deliver production, recoveries and costs that will enable GMIN to maintain itsr exceed 2026 production guidance and meet its revised 2026 cash costs and AISC guidance, as well as its overall 2027 guidance; (v) advancement of Oko will remain fully funded through construction, commissioning and ramp-up to commercial production, and will remain on schedule and within budget (in particular, detailed engineering and procurement will be completed in Q3-2026); (vi) GMIN’s positive safety and environmental records will remain stable and continue over time; (vii) the expected benefits of the G2 acquisition will ever materialize; (viii) GMIN will meet guidance, even if it was reiterated above; (ix) any of GMIN’s exploration activities at TZ, Oko West and Gurupi will generate positive results, which will in turn lead to additional resources and reserves, and eventually to additional gold production; (x) Oko will deliver first gold pour in H2-2027 and will achieve commercial production in early 2028, or at all; (xi) GMIN will achieve all or any of the milestones contemplated for 2026 at Gurupi (e.g., PEA, ESIA); or (xii) GMIN will use TZ and Oko West to grow into the next mid-tier precious metals producer, as future events could differ materially from what is currently anticipated by the Corporation. In addition, there can be no assurance that Brazil and/or Guyana will remain mining friendly and prospective jurisdictions.

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks exist that estimates, forecasts, projections and other forward-looking statements will not be achieved or that assumptions do not reflect future experience. Forward-looking statements are provided for the purpose of providing information about management’s expectations and plans relating to the future. Readers are cautioned not to place undue reliance on these forward-looking statements as several important risk factors and future events could cause the actual outcomes to differ materially from the beliefs, plans, objectives, expectations, anticipations, estimates, assumptions and intentions expressed in such forward-looking statements. All of the forward-looking statements made in this press release are qualified by these cautionary statements and those made in the Corporation’s other filings with the securities regulators of Canada including, but not limited to, the cautionary statements made in the relevant sections of the Corporation’s (i) Annual Information Form dated March 25, 2026, for the financial year ended December 31, 2025, and (iii) Management Discussion & Analysis. The Corporation cautions that the foregoing list of factors that may affect future results is not exhaustive, and new, unforeseeable risks may arise from time to time. The Corporation disclaims any intention or obligation to update or revise any forward-looking statements or to explain any material difference between subsequent actual events and such forward-looking statements, except to the extent required by applicable law.
