G Mining Ventures targets stronger H2 after record cash flow, TZ throughput milestone

G Mining Ventures (GMIN) reported a robust Q2 2025, achieving record free cash flow of $60.2 million and revenue of $129.6 million, with gold production up 20% to 42,587 ounces as its Tocantinzinho (TZ) mine reached 86% of nameplate capacity. The company anticipates a stronger second half as TZ enters steady-state, positioning GMIN to self-fund its development pipeline, including progress at Oko West and Gurupi, and reaffirmed its 2025 production guidance of 175,000-200,000 ounces despite analyst notes on potential full-year costs.

Analysis

G Mining Ventures reported a significant operational and financial ramp-up in its second quarter of 2025, generating a record $60.2 million in free cash flow and $129.6 million in revenue. This performance was driven by a 20% quarter-over-quarter increase in gold production to 42,587 ounces at its flagship Tocantinzinho (TZ) mine, which is now approaching design capacity. Key operational metrics showed marked improvement, with average plant throughput rising to 86% of nameplate capacity from 78% in Q1, and recovery rates increasing to 90.3%. The reported all-in sustaining cost of $1,355 per ounce was influenced by one-time fleet purchases, suggesting potential for cost normalization ahead. The strong cash flow has bolstered the company's balance sheet, with cash reserves rising to $156.1 million, supporting the management's strategy to self-fund its development pipeline without near-term external capital. Progress on this pipeline is evident, with a construction decision for the Oko West project anticipated in H2 2025 and regulatory hurdles being cleared at the Gurupi project. While the company reaffirmed its full-year production guidance of 175,000 to 200,000 ounces, commentary from Jefferies analysts introduces a note of caution, suggesting that higher costs and a new state tax could push results toward the lower end of that range, even as they project stronger production in the second half.

Key Decisions for Investors

• Investors should recognize the strong operational momentum at the Tocantinzinho mine, as achieving full nameplate capacity and higher recovery rates in the second half could drive production and free cash flow above Q2's record levels.
• It is prudent to monitor all-in sustaining costs and the impact of the new state tax, as these factors could pressure margins and push full-year production towards the lower end of the 175,000-200,000 ounce guidance, as noted by Jefferies.
• Key upcoming catalysts in H2 2025, specifically the final environmental permit and subsequent construction decision for the Oko West project, are critical milestones for the company's growth trajectory towards becoming a multi-asset producer.
• Consider the company's strengthened balance sheet and ability to self-fund its development pipeline from robust cash flow, which reduces near-term dilution risk typically associated with external capital raises for growth projects.
