G Mining Ventures Reports Q4 and Full-Year 2025 Results; First Full Year of Commercial Production at Tocantinzinho Drives Strong Cash Flow Generation
G Mining transitions to mid-tier status as Tocantinzinho cash flow fuels the $1B Oko West build
The most recent news (March 25, 2026) confirms that G Mining Ventures (GMIN) has successfully completed its first full year of commercial production at the Tocantinzinho (TZ) mine in Brazil. The operation generated $255 million in free cash flow in 2025, meeting production and cost expectations. Looking forward, GMIN has provided 2027 guidance for TZ of 200,000 to 235,000 ounces, representing a significant increase in production with a projected 21% decrease in All-In Sustaining Costs (AISC). Simultaneously, the Oko West project in Guyana is progressing on schedule for a Q4 2027 gold pour, with 43% of the capital budget already committed.
The news is Material - Positive. The transition from a developer to a profitable producer at TZ is now fully validated by a year of financial data. - Cash Flow Engine: The $255M in free cash flow from TZ provides a massive internal funding source for the $973M Oko West build, reducing the need for dilutive equity financing. - Reserve Growth: The March 12 update showing a 221% increase in reserves (to 6.52 Moz) significantly extends the company's life-of-mine and valuation floor. - Strategic Validation: The March 9 announcement that La Mancha exercised its top-up right to maintain a 19.9% stake at CAD 45.89 per share (raising CAD 427M) provides a massive cash cushion and a strong vote of confidence from a sophisticated mining investor. - Operational De-risking: Solving the SAG mill liner issues (noted in the transcript) has allowed the plant to run at 108% of nameplate capacity, proving the "Buy, Build, Operate" model works.
