G Mining Ventures Reports Third Quarter 2026 Results - Strong Free Cash Flow Driven by Solid Operational Performance; On Track to Achieve 2026 Production and Cost Guidance

BROSSARD, QUÉBEC, Nov. 12, 2026 (GLOBE NEWSWIRE) -- G Mining Ventures Corp. (“GMIN” or the “Corporation”) (TSX: GMIN, OTCQX: GMINF) today reported financial and operating results for the third quarter ended September 30, 2026. Unless otherwise indicated, all dollar amounts are in U.S. dollars. Louis-Pierre Gignac, President and Chief Executive Officer, commented: “TZ continues to perform well and remain closely aligned with the operating plan, reflecting the consistent execution of our team. Solid operational performance contributed to strong free cash flow, funding construction activities at Oko. We expect a further increase in throughput, mining rates, as well as higher grades, which will drive a significant increase in production in the fourth quarter, at lower costs, and remain on track to achieve our annual production and cost guidance. “We are making excellent progress across our project pipeline. 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. At Gurupi, the ESIA continues to progress and an updated MRE is expected to be complete before year-end, which will form the basis of a Preliminary Economic Assessment (“PEA”) targeted by the end of 2026.” Third Quarter 2026 Highlights Solid operational quarter driven by strong execution and cost control - Tocantinzinho (“TZ”) delivered gold production of 44,960 ounces in the third quarter, a 22% increase over the second quarter of 2026 driven by higher grade from mine sequencing, higher throughput and recoveries. Total cash costs (1) of $960 per ounce sold were 8% lower than the second quarter, and All-In Sustaining Costs (“AISC”)(1) of $1,591 per ounce sold were 6% lower than the second quarter, largely driven by higher production. We continue to expect full-year cost to finish within our guidance range despite industry-wide inflationary pressures, which reflects our strong cost discipline. 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 $99.5 million or $0.36 per basic share and adjusted net income (1) of $88.8 million or $0.32 per basic share. Cash provided by operating activities before net change in working capital totaled $114.8 million, while free cash flow(1) reached $80.0 million. Annual gold production tracking to midpoint of guidance range; total cash costs and AISC annual guidance reiterated - Gold production is expected to increase in the fourth quarter, driven by a full-quarter contribution of higher-grade Phase 2 ore. As such, full-year production is tracking to the midpoint of the guided range of 160,000 to 190,000 ounces of gold for 2026. Full-year total cash costs per ounce and AISC per ounce guidance for 2026 remains unchanged at $836 to $965 and $1,330 to $1,544, respectively. Total capital expenditures guidance for 2026 (excluding capitalized exploration) remains unchanged at $583 to $649 million. Capitalized exploration is expected to be approximately $11 million above previous guidance for 2026 of $42 to $50 million due to the infill program launched in the third quarter to advance the integration of the Oko-Ghanie deposits into the expanded Oko Gold Project located in Guyana (“Oko Gold”). Further details are set out in the outlook section below. Oko Gold construction continues to progress on-budget and on-schedule for first gold pour in the second half of 2027 - As of September 30, 2026, $556 million had been spent on the Project, representing 57% of the approved initial capital budget of approximately $973 million, with approximately $417 million remaining to be spent through completion. Total commitments reached approximately $714 million, or 73% of the approved capital budget. Share repurchases – On August 28, 2026, the Toronto Stock Exchange (“TSX”) has accepted the Corporation’s notice of intention to launch a normal course issuer bid (“NCIB”). During the third quarter of 2026, GMIN repurchased and cancelled 102,500 common shares for $3.6 million (C$5.1 million), at an average price of C$49.41 per share. GMIN believes the NCIB offers flexibility to deploy cash strategically in line with its capital allocation priorities and market conditions, while preserving the financial capacity to invest in future growth. Strong balance sheet maintained through heavy growth capital expenditures – As of September 30, 2026, cash and cash equivalents totaled $137.0 million and long-term debt was $31.2 million, resulting in a net cash position of $105.8 million. Overview of Financial and Operating Highlights Production: TZ produced 44,960 ounces of gold in the third quarter of 2026, 3% lower than the prior year period and a 22% increase from the previous quarter. Mining rates increased to average a record of 74,209 tpd in the third quarter, 35% higher than the prior year period and a 7% increase from the previous quarter. Milling rates averaged a new quarterly record of 12,372 tpd during the third quarter, a 4% increase from the prior year period and an 11% increase over the second quarter. Grades processed averaged 1.33 g/t Au during the third quarter, slightly below the prior year period but increased by 8% over the second quarter. Mill recoveries averaged 92.0% in the third quarter, in line with expectations. Gold production is expected to increase in the fourth quarter, driven by a full-quarter contribution of higher-grade Phase 2 ore. Costs: Total cash costs (1) of $960 per ounce sold and AISC (1) of $1,591 per ounce sold in the third quarter of 2026 were higher than the prior-year period due primarily to lower production volumes, higher royalties, and a stronger Brazilian real relative to the U.S. dollar. In addition, AISC (1) was impacted by higher sustaining capital expenditures and higher general and administrative expenses. For the first nine months of the year, total cash costs (1) of $1,010 per ounce sold and AISC (1) of $1,622 per ounce sold were higher than the prior year period, driven by the same factors. Total cash costs (1) and AISC (1) are expected to decrease in the fourth quarter bringing full year costs in line with annual guidance. Capital Expenditures: Sustaining capital expenditures at TZ in the third quarter 2026 were $14.8 million, focused on the existing Tailings Storage Facility (“TSF”) dam raise, additional mining equipment and plant enhancements. In the third quarter of 2026, development capital expenditures at Oko Gold were $132.8 million and capitalized exploration expenditures were $16.2 million. For the first nine months of 2026, TZ sustaining capital expenditures were $27.6 million, Oko Gold development capital expenditures were $352.7 million and capitalized exploration were $30.0 million. Revenue: For the three and nine months ended September 30, 2026, the Corporation sold 43,110 oz and 114,325 oz at an average realized gold price(1) of $4,007/oz and $4,109/oz respectively, contributing to revenues of $172.7 million and $469.8 million, respectively. Differences between gold ounces produced and gold ounces sold are primarily due to shipment and refining timing differences. Net Income and Adjusted Net Income: Third quarter 2026 net income was $99.5 million ($0.36 per share) compared to net income of $72.0 million ($0.30 per share) in the second quarter of 2026. Adjusted net income(1) was $88.8 million ($0.32 per share). Adjusted net income includes the following adjustments for the third quarter: $(9.3) million related to the change in fair value of financial instruments and $(1.1) million related to the present value adjustment of value added taxes receivable. Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”)(1): Adjusted EBITDA(1) increased when compared to the prior-year period primarily due to higher revenues from mining operations (higher realized gold prices, partially offset by lower gold sales), partially offset by higher production costs (higher labour costs, royalty costs and energy costs). Cash Provided by Operating Activities: Cash provided by operating activities of $46.0 million in the third quarter of 2026 decreased when compared to the prior-year period and second quarter of 2026, primarily as a result of a $57.1 million cash outflow during the quarter related to the changes in operating assets and liabilities subsequently to the acquisition of G2 Goldfields Inc. (“G2 acquisition”). Cash provided by operating activities before changes in working capital was $114.8 million, an increase of 7% when compared to the prior-year period and an increase of 9% when compared to the second quarter of 2026.

The Corporation remains on track to achieve its 2026 production guidance of 160,000 to 190,000 ounces of gold. Production is expected to increase in the fourth quarter and to be the strongest quarter of the year, driven by increased throughput and ounces by a full-quarter contribution of higher-grade Phase 2 ore. For the first nine months of the year, total cash costs(1) of $1,010 per ounce sold and AISC(1) of $1,622 per ounce sold were higher than the prior year period, driven by the same factors. Total cash costs(1) and AISC(1) are expected to decrease in the fourth quarter due to higher production and lower operating costs, bringing full year costs in line with annual guidance. For the first nine months of 2026, sustaining capital expenditures were $27.6 million, Oko Gold development capital expenditures were $352.7 million and capitalized exploration were $30.0 million. Total capital expenditures guidance for 2026 (excluding capitalized exploration) remains unchanged at $583 to $649 million. Exploration capital is expected to be approximately $11 million above guidance for 2026 of $42 to $50 million due to the infill program launched in the third quarter to advance the integration of the Oko-Ghanie deposits into Oko Gold. Given its strong outlook with significant free cash flow growth expected in the next several years, the Corporation expects to continue to be active in its share buyback while balancing its other capital allocation priorities. 2026 and 2027 Guidance Operational & Cost Guidance   Q3 2026 YTD Actuals 2026 Guidance(2) 2027 Guidance(2) In millions of $, except as otherwise noted         Gold Production k oz 114 160 - 190 200 - 235(4) Total Cash Costs(1) $/oz Au 1,010 836 – 965 633 - 743 Site-Level AISC(1) $/oz Au 1,501 1,233 - 1,430 898 - 1,054 AISC(1) $/oz Au 1,622 1,330 - 1,544 977 - 1,146 Sustaining Capital Expenditures         Sustaining $ 27 38 - 45 19 – 23 Capitalized Stripping $ 26 31 - 36 43 – 51 Exploration (Sustaining) $ 2 - - Total Sustaining Capital Expenditures $ 55 69 - 81 62 – 74 Non-Sustaining Capital Expenditures(3)         TZ Exploration $ 4 8 - 10 8 - 10 Oko Gold Exploration $ 14 26-28 was 15-17 14 - 18 Gurupi Exploration $ 12 19 - 23 18 - 22 Total Exploration $ 30 53-61 40 - 50 Oko Gold Development $ 353 514 - 568 217 - 240 Total Non-Sustaining Capital Expenditures $ 383 567 - 629 257 - 290 Advancing the Next Phase of Transformational Growth Oko Gold The Corporation continues to rapidly advance its large-scale, long-life Oko Gold Project in Guyana, which remains on-budget and on-schedule for a first gold pour in the second half of 2027. At the end of the third quarter, $556 million was spent on the Project, representing 57% of the approved initial capital budget of $973 million, with approximately $417 million remaining to be spent through completion. Total commitments reached $714 million, or 73% of the approved capital budget. Total capital expenditures guidance at Oko Gold for 2026 and 2027 remain unchanged at $514 to $568 million, and $217 to $240 million respectively. As of September 30, 2026, overall project progress at Oko Gold had reached 38.4% based on earned value, with rapid progress made across several key workstreams summarized below: On-site workforce now exceeds 2,100 employees and contractors, with 3.3 million hours worked to the date, and with over 78% local employments, demonstrating the Corporation’ s commitment to local content. Process plant construction continues to rapidly advance towards first gold pour in the second half of 2027: Carbon-In-Leach, pipe racking and Carbon in Pulp (“CIP”) Tanks are well underway with significant progress in October. Mill construction continues to advance with the mill shells delivered on-site marking the commencement of mechanical installation. Installation of pre-leach thickener rings ongoing, with ring pours progressing as planned. Foundation construction began on schedule for the process water tank. Power plant construction continues to advance ahead of schedule with mechanical module installation inside the engine hall and in the fuel treatment area completed and all generators were received, positioned, aligned and secured. Primary crusher concrete works reached 32% as wall construction and Mechanical Stabilized Earth (MSE) wall preparation ongoing. TSF earthworks continue to progress with the removal of alluvial material ongoing. Engineered fill placement on the Main Starter Dam has surpassed 44,000 m³, while grubbing activities at the South Dyke have exceeded 2,300 m³. Construction of the ore reclaim tunnel progressing well with completion of the mat foundation and the commencement of wall installation. Construction of the administration building continue to progress on schedule, with slab and foundation works completed and structural steel installation underway. Mining fleet includes eight fully commissioned and operational HD1500 haul trucks, along with three D375A-8 dozers. Assembly of the third PC4000 production shovel nearly complete. 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 launched 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 study for an expanded Oko Gold Project which will integrate the Ghanie and Oko Main deposits. Complementary technical programs, including metallurgical, geotechnical, and other engineering studies, has commenced.

Engineered fill placement on the Main Starter Dam has surpassed 44,000 m³, while grubbing activities at the South Dyke have exceeded 2,300 m³. A photo accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/2bb04e32-9d12-405a-9ce6-2cea1390c36b Mining activities remain focused on the Oko-Ghanie Quarry Pit, where fresh rock is closest to surface compared to other pits. This material is required to support ongoing construction activities and development of the haul road network for the expanding mining fleet. Gurupi At Gurupi, capitalized exploration expenditures were $5.6 million in the third quarter of 2026 and $12.0 million for the first nine months of 2026. Drilling continues to demonstrate extensions to known mineralization at the Blanket and Mandiocal deposits while maiden drilling at the Grodiocal target has identified multiple zones with near surface gold mineralization within a corridor extending approximately 5 kilometer (“km”) in strike length and up to 1 km in width. An updated MRE is expected to be complete before year-end, which will form the basis of a PEA targeted to be completed by the end of 2026. Exploration Activities On September 16, 2026, the Corporation provided an update on its drilling and exploration programs at both Gurupi and TZ. Results to date support the Corporation's strategy to grow reserves and resources, extend mine life, and enhance the long-term production profile across its portfolio of assets. Latest exploration results published to date can be found in GMIN’s press release dated September 16, 2026. At TZ, drilling continues to show promising results that highlight the potential to offset reserve depletion and to add to the resource inventory. Drilling up to 150 metres below the current pit design confirmed the continuity of mineralization at depth. Initial results from regional drilling programs defined a 15 km by 3 km mineralized corridor hosting multiple satellite targets, which is early indication providing the case for continued exploration efforts. At Oko Gold, the exploration strategy remains focused on: (i) increasing confidence in and evaluating opportunities to expand mineral resources along the Oko West-Oko-Ghanie mineralized corridor; (ii) integrating the GMIN and G2 datasets to enhance geological interpretation and target generation across the broader land package; and (iii) continuing regional exploration to identify additional zones of mineralization. Following the closing of the G2 Acquisition, the exploration program was refocused to prioritize infill drilling at Oko-Ghanie and the integration of the GMIN and G2 geological and exploration datasets across the combined land package. The Oko-Ghanie infill drilling program commenced during the quarter and is expected to be completed by year-end. Capitalized exploration expenditures in the third quarter of 2026 were $16.2 million, including $9.1 million at Oko Gold, $5.6 million at Gurupi and $1.5 million at TZ. Capitalized exploration expenditures for the first nine months of 2026 were $30.0 million, including $13.8 million at Oko Gold, $12.0 million at Gurupi and $4.2 million at TZ. Total capitalized exploration expenditures for 2026 is expected to be approximately $11 million above guidance for 2026 of $42 to $50 million due to the infill program launched in the third quarter to advance the integration of the Oko-Ghanie deposits into the expanded Oko Gold Project. Environmental, Social & Governance (ESG) During the third quarter of 2026, TZ's environmental performance remained strong and aligned with regulatory requirements and GMIN standards. Monitoring programs ran as planned. There was one significant spill that was rapidly contained with no ensuing environmental impact. In addition, permitting moved forward: the Installation License for the TSF raise to elevation 161 was issued in June 2026, and several other permits are progressing with Secretaria de Meio Ambiente e Sustentabilidade (“SEMAS”). The exploration permitting package advanced significantly following the execution of the land access agreement required for the installation of the exploration fly camp, with permit issuance expected during the fourth quarter of 2026. An independent gap assessment found 71% alignment with Toward Sustainable Mining and 61% with Global Industry Standard on Tailings Management. A roadmap and corrective action plan to close those gaps are being finalized. Water management at the TSF and Cyanide Tailings Storage Facility stayed within expectations. Regarding social activities, TZ approved 18 community investment initiatives and continued work toward a Multi-Stakeholder Community Committee and a cooperation framework with artisanal miners. The grievance mechanism received 44 cases and closed 38, and there were no security incidents. TZ also began its largest community investment to date: the R$11 million revitalization of the Itaituba waterfront under Pará's Estrutura Pará Program. The project is funded through the redirected Mining Resources Inspection Fee and is expected to benefit to more than 120,000 residents. At Gurupi, environmental and social activities during the third quarter of 2026 remained focused on advancing environmental permitting and baseline studies for the Environmental and Social Impact Assessment ("ESIA"), supporting exploration activities, strengthening stakeholder engagement and progressing the environmental and social workstreams required for the Gurupi Project’s development. The permitting roadmap continues to target completion and filing of the ESIA with SEMAS in the fourth quarter of 2026, subject to regulatory timelines and the successful completion of field programs.

Such assumptions include, without limitation, those relating to GMIN’s industry-leading near term growth profile, those relating to GMIN continuing to generate strong free cash flow and strong profitability, those relating to the price of gold (in particular, its anticipated continued strength), and currency exchange rates, those outlined in the feasibility and other technical studies relating to GMIN’s mining assets, those relating to government royalties, taxes (including tax incentives) and withholdings, those supporting GMIN’s annual production and cost guidance, and those underlying the items listed on the above sections entitled “Outlook”, “Advancing the Next Phase of Transformational Growth”, and “About G Mining Ventures Corp.”. Many of these uncertainties and contingencies can directly or indirectly affect, and could cause, actual results to differ materially from those expressed or implied in any forward-looking statements. There can be no assurance that, notably but without limitation, (i) the G2 acquisition will transform Oko Gold into a globally significant Tier-One gold asset; (ii) GMIN’s integration program for G2’s Oko-Ghanie will meet expectations, notably the Oko Gold expansion that will create a Tier-One gold asset with potential to deliver substantially increased gold production; (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 meet its 2026 production, cash costs and AISC guidance, as well as its overall 2027 guidance; (v) the advancement of Oko Gold will remain fully funded through construction, commissioning and ramp-up to commercial production, and will remain on schedule and within budget for first gold pour in H2-2027; (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) the continuing regional exploration will identify additional zones of mineralization; (ix) any of GMIN’s exploration activities at TZ, Oko Gold and Gurupi will continue to show promising results and will demonstrate extensions to known mineralization, which will in turn lead to additional resources and reserves (offsetting reserve depletion), and eventually to additional gold production; (x) Oko Gold 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); (xii) GMIN’s free cash flow will grow over the next years; or (xiii) GMIN will use TZ and Oko Gold 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.
