Highlights from the 2024 Climate Strategy Update

2024 Highlights

• B2Gold is committed to a GHG emissions reduction target of a 30% reduction in Scope 1 and 2 emissions by 2030 against a 2021 baseline.
  
  
• The Company continued evaluation of financial impacts of key climate risks identified at sites during previous climate scenario analysis workshops.
  
  
• The total Scope 1 and 2 GHG emissions (for the Fekola, Masbate and Otjikoto operations) remained relatively stable in 2024, with a slight decrease to an estimated 699 thousand tonnes CO ₂ e compared to 701 thousand tonnes in 2023. The Company's consolidated GHG emissions intensity was 0.89 tonnes CO ₂ e per gold ounce produced in 2024 (compared with 0.71 in 2023), a modest increase driven in part by a reduction in total gold production.

Looking Forward – 2025 and Beyond

In 2025, B2Gold looks forward to strengthening its global partnerships and deepening its commitment to the diverse communities in which it operates. The Company will continue investing in initiatives that expand vocational training and promote job creation, improve access to education, and enhance healthcare services. B2Gold believes that by building local capacity and fostering strong alignment among governments, communities, stakeholders, and the Company, it can help create resilient, healthy, and prosperous communities throughout the mining lifecycle.

As part of its climate strategy, B2Gold will continue to advance renewable energy initiatives across its operations, supporting its target to reduce Scope 1 and 2 GHG emissions by 30% by 2030 against a 2021 baseline. At the Masbate Gold Project, an 8.2-megawatt ("MW") solar plant is scheduled for installation in 2025, which will further reduce emissions and heavy fuel oil ("HFO") consumption. In Nunavut, following regulatory approvals received in 2024, B2Gold is finalizing project plans and environmental commitments for the proposed Back River Energy Centre—a renewable energy facility that could include up to thirteen wind turbines, solar panels, and battery storage, with the potential to deliver more than 55 MW of clean energy. This facility is expected to significantly reduce reliance on HFO, as well as the number of fuel barges and fuel truck trips along the winter ice road.

Beyond increasing the share of renewable energy in its operations, B2Gold is actively assessing a range of additional carbon reduction opportunities, including energy efficiency improvements, the use of alternative fuels, and optimization of materials movement. The Company remains committed to innovation by working closely with industry-leading partners and staying prepared to adopt emerging technologies that align with its decarbonization goals.
