B2Gold Corp. (TSX: BTO) (NYSE: BTG) (NSX: B2G) is pleased to announce the first gold pour at the Goose Mine. The Goose Mine forms part of the Back River Gold District located in Nunavut, Canada, and is the Company’s fourth producing mine in the current operating portfolio and its first Canadian operating asset.

In announcing first gold production, Clive Johnson, President & CEO of B2Gold stated, “I am pleased to announce that the Goose Mine has achieved its inaugural gold pour, a true milestone for our staff and our partners who have worked tirelessly to reach this achievement. The commencement of gold production at the Goose Mine marks an exciting step in B2Gold’s history, further diversifying and adding to the quality of the Company’s existing global operating portfolio. We look forward to many years of safe and successful production at the Goose Mine, as well as further unlocking the value of the entire Back River Gold District.”

First ore was introduced to the Goose Mine processing facilities on June 24, 2025, and the mill has run consistently at approximately 50% of nameplate capacity during this initial phase, as planned. The focus during the third quarter of 2025 will be to continue steady state operations and increase throughput to full design capacity in the near-term. This will include synchronizing the remaining generators and ensuring that all process circuits continue to perform as designed.

B2Gold acknowledges our partner the Kitikmeot Inuit Association, who has played a critical role for many years to ensure the development of a successful gold mining operation at the Goose Mine. Respect and collaboration with the KIA is central to the license to operate in the Back River Gold District and B2Gold will prioritize operating the Goose Mine in a manner that recognizes Inuit priorities, addresses concerns, and brings long-term socio-economic benefits to the Kitikmeot Region. B2Gold looks forward to continuing to build on its strong collaboration with the KIA and Kitikmeot Communities.

With the first gold pour at the Goose Mine having been achieved, the Company expects a ramp up to commercial production in the third quarter of 2025. B2Gold continues to estimate that gold production in 2025 will be between 120,000 and 150,000 ounces, and that average annual gold production for the initial full six years of operations (2026 to 2031 inclusive) will be approximately 300,000 ounces per year, based only on existing Mineral Reserves. B2Gold’s exploration programs have been successful in upgrading Inferred Mineral Resources to Indicated Mineral Resources, and the Company anticipates that trend continuing moving forward. Significant exploration potential remains across the Back River Gold District. B2Gold’s corporate exploration budget is $61 million in 2025, with a total of $32 million budgeted for exploration at the Back River Gold District.
