G Mining Ventures reaches nameplate capacity at Tocantinzinho, boosts production in Q2

G Mining Ventures Corp's Tocantinzinho Gold Mine achieved nameplate capacity and significantly boosted Q2 2025 gold production by 20% quarter-over-quarter to 42,587 ounces, following the successful resolution of a SAG mill issue that enhanced operational stability and gold recovery to 90.3%. Despite first-half production of 78,165 ounces being marginally below the planned pace against its reaffirmed annual guidance, the company remains confident in achieving its 2025 targets, indicating a strong operational turnaround and continued focus on project development.

Analysis

G Mining Ventures has materially de-risked its Tocantinzinho (TZ) Gold Mine by reaching nameplate capacity and resolving a critical operational bottleneck, signaling a successful transition into steady-state production. The company's ability to increase Q2 gold production by 20% quarter-over-quarter to 42,587 ounces is a direct result of addressing the SAG mill liner issue in April. This fix led to a marked improvement in plant throughput, which surged from 67% of nameplate capacity in April to 96% in May and June, while gold recovery improved to 90.3%. Although first-half production of 78,165 ounces is slightly behind the planned run-rate at 42% of the guidance midpoint (versus a 44% plan), the strong operational metrics post-fix lend significant credibility to management's reaffirmed annual guidance of 175,000 to 200,000 ounces. The next critical data point for the market will be the cost guidance, scheduled for release with Q2 results on August 14, which will clarify the mine's profitability. Beyond TZ, the company's focus on securing the final permit and a construction decision for the Oko West project in H2 2025 presents a clear pipeline for future growth.

Key Decisions for Investors

• The primary operational risk at Tocantinzinho has been significantly mitigated, so investors should now focus on the upcoming cost guidance on August 14 to assess the mine's all-in sustaining costs and potential for free cash flow generation.
• While the reaffirmed production guidance is a positive signal, its achievability hinges on sustaining the strong operational performance seen in May and June through the second half of the year.
• Monitor progress on the Oko West project's final environmental permit and the subsequent financing decision in H2 2025, as these are the next key catalysts for the company's long-term growth profile.
