2 On October 15, 2019, B2Gold restructured its interests in La Libertad Mine and El Limon Mine and, as a result, now applies the equity method of accounting for its ownership in Calibre. Commencing from October 15, 2019, B2Gold reported an approx. 33% attributable share of Calibre production/costs as part of its total production/cost results.

3 On January 12, 2022, B2Gold’s ownership interest in Calibre was diluted to approx. 25% following Calibre’s acquisition of Fiore Gold Ltd. Throughout 2023, B2Gold’s ownership interest in Calibre was 24%. Effective January 24, 2024, B2Gold’s ownership interest in Calibre was diluted to approx.15% following Calibre’s acquisition of Marathon Gold Corp. Subsequent to June 20, 2024, B2Gold will no longer record attributable production for Calibre.

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 US$2,100/oz, metallurgical recovery of 98%, selling costs of US$87.02/oz including royalties and levies, and operating cost estimates of US$3.26/t mined (mining), US$13.92/t processed (processing) and US$3.96/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 1.5, 1.90 or 2.50 g/t Au and a minimum diluted thickness of 4.0 m. Underground resource reporting assumes a gold price of US$2,100/oz Au, process recovery of 98%, variable mining costs by mining method of US$75.76–140.46/t mined, processing cost of US$18.84/t processed, and a selling cost of US$87.94/oz Au produced.
  9. Gramalote Project: Mineral Resources are reported on a 100% project basis. The Mineral Resource estimate has an effective date of December 31, 2024. The Qualified Person for the Mineral Resource estimate is Andrew Brown, P.Geo., our Vice President, Exploration. Mineral Resources assume an open pit mining method and are reported within conceptual pit based on a gold price of US$2,100/oz, metallurgical recovery of 81.7–84% for oxide and 87.6–97.6% for sulphide, mining cost estimates of US$2.61–US$2.92/t mined (average mining cost), processing cost of US$6.02–US$6.17 for oxide, US$9.36–US$9.51/t for sulphide processed (processing) and US$2.34/t processed (site general),and selling costs of US$70.37/oz including royalties and levies.. Mineral Resources are reported at cut-off grades of 0.16 g/t Au for oxide and 0.19 g/t Au for sulphide.
  10. Goose Project and Back River District, including the Goose and George Claims Groups: Mineral Resources are reported on a 100% project basis. Mineral Resources have an effective date of December 31, 2024. The Qualified Person for the Mineral Resource estimate is Andrew Brown, P.Geo., our Vice President, Exploration.
  11. Goose Claims Group: Mineral Resource estimates that are amenable to open pit mining methods are reported within conceptual open pit shells based on a gold price of US$2,100/oz, metallurgical recovery of 92.5%, selling costs of US$107.50/oz Au including royalties and levies, and operating cost estimates of US$5.99–6.63/t mined (mining), US$32.40–32.72/t processed (processing) and US$22.27/t processed (site general), pit slope angles of 45º, and an exchange rate of C$1.33:US$1.00. Mineral Resources potentially amenable to open pit mining methods are reported at an average cut-off grade of 0.9 g/t Au. Mineral Resource estimates potentially amenable to underground mining are reported at a cut-off grade of 2.2 g/t Au, assuming a gold price of US$2,100/oz Au, process recovery of 92.5%, variable mining costs by deposit of US$134.20–171.18/t mined, processing cost of US$54.72/t processed, and a selling cost of US$107.50/oz Au produced. No stope or other constraint was applied.
  12. 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 US$2,100/oz, metallurgical recovery of 92.5%, selling costs of US$107.50/oz Au including royalties and levies, and operating cost estimates of US$6.56/t mined (mining), US$57.94/t processed (processing) and US$26.55/t processed (site general), pit slope angles of 43º, and an exchange rate of C$1.33:US$1.00. 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 US$2,100/oz Au, process recovery of 92.5%, mining costs of US$175.46/t mined, processing cost of US$84.50/t processed including haulage, and a selling cost of US$107.50/oz Au produced. No stope or other constraint was applied.
  13. Stockpiles: Mineral Resources in stockpiled material are reported in the totals for the Fekola Mine, the Masbate Gold Project, the Goose Project and the Otjikoto Mine and were prepared by mine site personnel at each operation. Ore stockpile balances are derived from mining truck movements to individual stockpiles or detailed surveys, with grade estimated from routine GC.
  14. All tonnage, grade and contained metal content estimates have been rounded; rounding may result in apparent summation differences between tonnes, grade, and contained metal content.
