B2Gold to Consolidate Gramalote Project by Acquiring AngloGold Ashanti’s 50% Stake

Vancouver, BC, September 18, 2023 – B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX:

B2G) (“B2Gold” or the “Company”) is pleased to announce that is has entered into a purchase agreement

with AngloGold Ashanti Limited (“AngloGold”) to acquire AngloGold’s 50% stake in the Gramalote

project (the “Transaction”), located in the Department of Antioquia, Colombia (the “Gramalote Project”).

Upon completion of the Transaction, B2Gold will own 100% of the Gramalote Project.

Transaction Highlights

• Consolidates the Gramalote Project under one owner, providing additional optionality to

analyze lower capital intensity , higher -return development opportunities for the Project:

Historically, the Gramalote Project has been advanced under a joint venture between B2Gold and

AngloGold, which has led to analyzing the project on a large r scale basis to provide meaningful

production growth to both companies. Under a single owner, different development opportunities

will be assessed with the goal of delineating a project that maximizes the return for B2Gold as sole

owner of the Gramalote Project.

• Accretive to B2Gold shareholders on a total gold resource per share basis: With the

Transaction, B2Gold will add 2.11 million gold ounces of Indicated Mineral Resources and 0.74

million gold ounces of Inferred Mineral Resources to the Company’s con solidated Mineral

Resource base.

• B2Gold’s in -house projects team to commence work on various smaller scale project

development plans, with the goal of identifying a higher -return project than the previously

contemplated joint venture development plan : Based on the results of the 2022 Gramalote

feasibility study, the contemplated larger scale project did not meet the combined investment return

thresholds for development by both B2Gold and AngloGold. B2Gold plans to commence a detailed

review of the Gramalote Project, including the facility size and location, power supply, mining and

processing options, tailings design, resettlement, potential construction sequencing and camp

design to identify potential cost savings to develop a smaller scale project. The results of the review

will allow the Company to determine the optimal parameters and assumptions for a formal study ,

to commence in the fourth quarter of 2023, with the goal of completing an initial assessment by the

end of the second quarter of 2024.
