Recent Drilling Results and Ongoing Technical Review Highlights Significant

As of November 7, 2024, B2Gold had completed 25,126 m of drilling over 68 drill holes at the Goose Project, including 14,480 m over 40 drill holes at the Umwelt deposit, 3,899 m over 14 drill holes at the Llama deposit area, 6,610 m over 13 exploration target drill holes, and 137 m over one metallurgical hole at the Goose Main deposit. Significant drill hole locations from 2024 are shown on the map in Figure 1.

Goose Project Drill Results   Highlights

• Exploration drilling intersected high-grade mineralization 1,000 m west and down plunge of the Goose Main deposit at the Goose Project’s Nuvuyak deposit
  • Drill hole 24GSE-683Z1 returned 6.39 grams per tonne (“g/t”) gold over 28.80 m from 982.20 m, including a higher-grade interval of 23.49 g/t gold over 6.45 m and 4.66 g/t gold over 20.94 m from 1,037.16 m, including 8.60 g/t gold over 9.62 m; and
  • This result demonstrates the continuity of high-grade zones within the Nuvuyak deposit by extending high-grade gold mineralization approximately 150 m to the north-northwest.
• Exploration drilling also intersected high-grade mineralization at the Mammoth target 450 m up plunge of the Nuvuyak deposit towards the Goose Main deposit
  • Mammoth drill hole 24GSE-687Z1 returned 17.45 g/t gold over 10.96 m from 837.14 m, including a higher-grade interval of 68.61 g/t gold over 2.51 m;
  • Mammoth drilling tested down plunge of the fold between the Nuvuyak deposit and the Hook target; and
  • This result demonstrates that the Nuvuyak and Mammoth zones have strong potential for future underground mining.
• The Nuvuyak deposit and Mammoth target are not included in the existing Goose Project mine plan; these exploration results demonstrate potential to further increase Mineral Resources and extend the mine life at the Goose Project

• Drill   results   for   infill   and   mine   development at   the   Goose   Project’s   Umwelt deposit   confirm   the   continuity   of   high-grade   gold   mineralization,   with   several   drill   holes   returning intercepts   with   higher   gold   grades   and   widths   than   predicted   by   the existing mineral   resource   model
  • Drill hole 24GSE-671 returned 27.28 g/t gold over 11.10 m from 457.80 m;
  • Drill hole 24GSE-675 returned 19.63 g/t gold over 15.95 m from 389.85 m;
  • Drill hole 24GSE-677Z3 returned 9.27 g/t gold over 13.58 m from 664.25 m;
  • Drill hole 24GSE-681 returned 11.18 g/t gold over 15.50 m from 779.45 m;
  • Drill hole 24GSE-684B returned 29.49 g/t gold over 22.79 m from 332.25 m; and
  • Drill hole 24GSE-685 returned 10.51 g/t gold over 21.45 m from 306.00 m.

• Exploration drilling intersected high-grade gold mineralization 530 m down plunge from the estimated open pit boundary at the Goose Project’s Llama deposit
  • Drill hole 24GSE-663 returned 14.34 g/t gold over 27.95 m from 406.05 m, including a higher-grade interval of 54.17 g/t gold over 6.00 m and 205.00 g/t gold over 0.80 m, at a vertical depth of 370 m, which tested an…
