George Claims Group: Mineral Resources potentially amenable to open pit mining methods are reported within conceptual open pit shells based on a gold price of $2,500/oz, metallurgical recovery of 92.5%, selling costs of $127.98/oz Au including royalties and levies, and operating cost estimates of $7.80/t mined (mining), $68.98/t processed including haulage (processing) and $31.61/t processed (site general), and pit slope angles of 45º. Mineral Resources potentially amenable to open pit mining methods are reported at an average cut-off grade of 1.4 g/t Au. Mineral Resource estimates potentially amenable to underground mining are reported at a cut-off grade of 3.1 g/t Au, assuming a gold price of $2,500/oz Au, process recovery of 92.5%, mining costs of $208.88/t mined, processing cost of $100.59/t processed including haulage, and a selling cost of $127.98/oz Au produced. No stope or other constraint was applied.
  15. Masbate Gold Project: Mineral Resources are reported on a 100% project and attributable basis. Pursuant to the ore sales and purchase agreement between Filminera and PGPRC, our wholly-owned subsidiary, PGPRC has the right to purchase all ore from Filminera. B2Gold has a 40% interest in Filminera, which owns the mineral tenements, and the remaining 60% is owned by a Philippines-registered company, Zoom. Please see “Material Properties - Masbate Gold Project” below for a further discussion of the foregoing. The Mineral Resource estimate for the Masbate Gold Project accounts for mining depletion as of December 31, 2025. The Mineral Resource estimate has an effective date of December 31, 2025. The Qualified Person for the Mineral Resource estimate is Michael Johnson, P.Geo., our Technical Services Manager. The Qualified Person for the Mineral Resources in stockpile estimate is Peter Montano, P.E., our Vice President, Projects. Mineral Resources are reported within conceptual open pit shells based on a gold price of $2,500/oz, modeled metallurgical recovery (resulting in average metallurgical recoveries by resource area that range from 60-89%), and operating cost estimates of $1.57–$2.06/t mined (mining), $14.49/t processed (processing), $2.36–$3.82/t processed (general and administrative) and a selling cost of $106.00/oz. Mineral Resources are reported at an average cut-off grade of 0.30 g/t Au.
  16. Otjikoto Mine: Mineral Resources are reported on a 100% project and a 90% attributable basis, the remaining 10% interest is held by EVI, a Namibian empowerment company. The Mineral Resource estimate for Otjikoto accounts for mining depletion as at December 31, 2025. The Mineral Resource estimate has an effective date of December 31, 2025. The Qualified Person for the Mineral Resource estimate is Andrew Brown, P.Geo., our Vice President, Exploration. The Qualified Person for the stockpile estimate is Peter Montano, P.E., our Vice President, Projects. Mineral Resource estimates that are amenable to open pit mining methods are reported within a conceptual open pit shell based on a gold price of $2,500/oz, metallurgical recovery of 98%, selling costs of $103.65/oz including royalties and levies, and operating cost estimates of $2.50/t mined (mining), $14.75/t processed (processing) and $3.70/t processed (site general). Mineral Resources that are potentially amenable to open pit mining are reported at a cut-off grade of 0.25 g/t Au. Mineral Resources that are potentially amenable to underground mining are reported at cut-off grades of 1.25, 1.45 or 2.20 g/t Au and a minimum diluted thickness of 4.0 m. Underground resource reporting assumes a gold price of $2,500/oz Au, process recovery of 98%, variable mining costs by mining method of $79.78– $146.95/t mined, processing cost of $19.14/t processed, and a selling cost of $103.65/oz Au produced.
  17. Gramalote Project: Mineral Resources are reported on a 100% project basis. The Gramalote Ridge, Trinidad and Monjas West estimates have an effective date of December 31, 2025. The Qualified Person for the Mineral Resource estimate is Stephen Jensen, P.Geo., our Exploration Manager, Americas.
  18. Mineral Resources for Gramalote Ridge are reported within conceptual open pit shells based on a gold price of $2,500/oz, metallurgical recoveries of 84% for oxide and 92.7–97.6% for sulphide, and operating cost estimates of an average mining cost of $2.50/t mined, processing cost of $5.14/t processed for oxide and $8.50/t processed for sulphide, general and administrative cost of $3.80/t processed and selling cost of $84.00/oz of gold produced.
  19. Mineral Resources for Trinidad are reported within conceptual open pit shells based on a gold price of $2,500/oz, metallurgical recoveries of 81.7% for oxide and 90.9% for sulphide, and operating cost estimates of an average mining cost of $2.30/t mined, processing cost of $5.14/t processed for oxide and $8.50/t processed for sulphide, general and administrative cost of $3.80/t processed and selling cost of $84.00/oz of gold produced.
  20. Mineral Resources for Monjas West are reported within conceptual open pit shells based on a gold price of $2,500/oz, metallurgical recoveries of 81.7% for oxide and 87.6% for sulphide, and operating cost estimates of an average mining cost of $2.48/t mined, processing cost of $5.29/t processed for oxide and $8.65/t processed for sulphide, general and administrative cost of $3.80/t processed and selling cost of $84.00/oz of gold produced.
