Summary
G Mining Ventures reported a 221% year-over-year increase in gold reserves, reaching 6.52 Moz Proven and Probable at an average grade of 1.60 g/t Au as of December 31, 2025. This growth was primarily driven by the completion of the Oko West Feasibility Study, which added 4.64 Moz of P&P reserves, alongside global mineral resources totaling 9.17 Moz Measured and Indicated and 1.17 Moz Inferred. The company also highlighted the conversion of 2.40 Moz of Inferred Resources to Indicated at Oko West and provided updates on the advancement of its Tocantinzinho and Gurupi projects.
Reasoning: G Mining Ventures reported a 221% increase in gold reserves to 6.52 Moz, driven by the completion of the Oko West Feasibility Study which added 4.64 Moz of P&P reserves. The company also updated its global resources to 9.17 Moz M&I and 1.17 Moz Inferred, with significant conversion of Inferred to Indicated at Oko West, and provided positive development updates for its three gold projects.
Positive factors
- Significant increase in gold reserves (221% year-over-year)
- Large total P&P reserves (6.52 Moz) and M&I resources (9.17 Moz)
- Oko West Feasibility Study completed, adding substantial reserves and outlining robust mine life
- Oko West advancing towards first gold production in H2 2027
- Conversion of 2.40 Moz Inferred Resources to Indicated category at Oko West

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
