Highlights from the Tenth Annual “Raising the Bar” Responsible Mining Report and Sustainability Strategy

In 2025, B2Gold issued its inaugural Sustainability Strategy outlining the Company’s priorities and goals, driving long-term commitments and proactive impact and risk management. The Sustainability Strategy outlines the Company’s sustainability purpose and vision and identified five pillars for success including: sourcing with integrity; healthy and safe workplaces; thriving communities; nature, water and climate resilience; and responsible closure. These pillars provide actionable pathways for global teams to execute on their unique site-specific priorities, through collaboration and innovation, and build a positive legacy with the communities we serve.

Economic Contribution

As a responsible gold miner, B2Gold aims to create and distribute economic value among its stakeholders. B2Gold’s economic performance is measured by the economic value that it generates for others, including payments to governments through taxes and royalties, local hiring and procurement and investment in communities. In 2025, B2Gold:

• Achieved total consolidated gold production of 979,604 ounces (including 14,554 ounces of pre-commercial production from the Goose Mine);
• Generated $3 billion in annual revenue;
• Paid $1 billion to governments (through taxes and royalties);
• Paid $344.8 million in employee wages and benefits; and
• Invested $14.3 million in its local communities¹.

B2Gold is committed to maximizing local and national economic benefits from its contracting and purchasing. The Company is conscious of the high priority that host communities and governments place on local procurement. In sourcing the goods and services necessary to run its operations, B2Gold gives preference to local businesses where possible, provided they meet minimum safety, quality, ethical, and cost requirements. In 2025, over $1 billion of goods and services were procured from local and host-country businesses (including companies registered with in-country subsidiaries). Several 2025 success stories are outlined in the Report.

People

As a reputable corporate citizen, B2Gold generates national employment and opportunities for people to develop their careers, trains employees to acquire new skills, and opens doors to women, under-represented groups and previously disadvantaged people. The Company fosters positive and productive engagement with employees, provides safe workplaces, and believes that investing in people attracts and retains talented individuals and assists in their abilities to provide for themselves, their families and their futures.

At the end of 2025, B2Gold employed 6,327² people across all operations. The Company continues to maintain high local employment rates by targeting recruitment efforts at regional and national levels. Across all operations, 97% of the total workforce, and 58% of Senior Management³ were comprised of national⁴ employees.

B2Gold values a diverse workforce. In recent years, the Company has made significant strides in advancing its Equity, Diversity and Inclusion initiatives. In 2021, the adoption of a Diversity Policy by the Company’s Board established a target of 30% female representation on the Board and in management-level positions, underscoring its commitment to promoting and achieving gender diversity at all levels of the organization. B2Gold is pleased to report that as of the end of 2025, 40% of Company directors identify as female.

Health and Safety

As a result of B2Gold’s focus on injury prevention, the Company is once again pleased to report that it has maintained a zero-fatality workplace for the tenth consecutive year. Additionally, B2Gold’s injury rates remained low in 2025, with a Lost Time Injury Frequency Rate (LTIFR) of 0.09.⁵ This slight increase in LTIFR is primarily due to an increased risk profile from mine construction at the Back River Gold District in Nunavut and development at the Gramalote Project in Colombia. The Company’s performance reflects the period of growth and underscores the Company’s position as a top safety performer within the industry.

In 2025, the three mature operations all achieved remarkable safety milestones. At Fekola, the team surpassed over 23 million LTI-free worker hours; at Masbate, the team achieved seven years LTI-free (over 45 million worker hours); and at Otjikoto, the team achieved the lowest TRIFR in the mine’s history. These accomplishments reflect the sustained improvements in safety performance across our operations and the dedication of our global teams to B2Gold safety culture and to ensuring every employee and contractor return HOME-SAFE.⁶

Communities

B2Gold maintains its social licence to operate by building trust-based relationships, actively engaging with stakeholders, and implementing community investment activities based on local ownership and development priorities. Highlights of the 2025 community investment programs include:

• At the Fekola Complex, B2Gold implemented its second large scale agricultural project, the 60-ha Bafarato Agricultural Project and continued its partnership with Global Affairs Canada supporting the FEMA Project. The FEMA Project aims to improve conditions for women and children living in artisanal mining communities within the Fekola Mine’s area of influence; the project was initiated in March 2022 and will continue until 2027.
• At the Masbate Gold Project, investment continued to focus on education, access to health services and facilities, and programs that enhance local economic opportunities, including skills training and small enterprise support. The Training for Employment Program reached its sixth year of partnership in 2025 and remains a powerful driver of economic mobility by equipping individuals with the skills and training needed to build sustainable livelihoods.
• At the Otjikoto Mine, B2Gold Namibia continues its investment activities in the Ombili Primary School in Otjiwarongo, which is expected to be completed and handed over to the Namibian Government by the end of 2026. This initiative serves as a wonderful example of how partnership can create lasting benefits that extend well beyond the mine’s operational life.
• At the Back River Gold District, B2Gold Nunavut continues to strengthen its close relationships with the Kitikmeot Inuit Association and communities across Canada’s Arctic. The Company is investing in collaborative projects throughout the Kitikmeot region that promote community wellness, support youth through sports, recreation, and education, and advance initiatives focused on women and Elders. In 2025, B2Gold also committed approximately C$11 million to support the construction of modular public housing units across Kitikmeot communities in partnership with the Government of Nunavut and the Nunavut Housing Corporation, recognizing the important role that safe and adequate housing plays in supporting healthy and resilient communities. Launched in September 2025, the Kitikmeot Social Investment Program is a notable initiative that seeks to help support sustainable investments in Kitikmeot Communities with positive multi-year impacts. B2Gold Nunavut remains committed to working alongside the Kitikmeot Inuit Association to advance further initiatives that ensure the benefits of the Back River Gold District reach the communities of Cambridge Bay, Kugluktuk, Gjoa Haven, Taloyoak, and Kugaaruk.

Environment

Our environmental strategy revolves around proactive identification, mitigation, and management of environmental impacts. In 2025, B2Gold finalized its “No Net Loss Roadmap,” which identifies opportunities to strengthen biodiversity management practices and address potential gaps related to the Company’s commitment to no net loss of critical habitat. The roadmap is intended to support site teams in identifying and managing potential impacts to critical habitat and in developing appropriate mitigation and conservation measures in collaboration with relevant stakeholders.

B2Gold remains firmly committed to reducing greenhouse gas (“GHG”) emissions, with a target to reduce Scope 1 and 2 emissions by 30% by 2030 against a 2021 baseline for its Fekola, Masbate and Otjikoto operations. Decarbonization and climate management highlights are presented in the following pages.

Approach to Reporting

B2Gold is committed to the transparency of its sustainability risks, management and performance. The Report is aligned with the Global Reporting Initiative Sustainability Reporting Standards and the Sustainability Accounting Standards Board Mining and Metals Sustainability Accounting Standard. The Company firmly believes that the mining industry has an opportunity to contribute positively to the United Nations Sustainable Development Goals and it has reported its contribution in this regard since 2018.

Highlights from the 2025 Climate Strategy Report

2025 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 for its Fekola, Masbate and Otjikoto operations.
• The Fekola, Masbate, and Otjikoto operations developed site-specific GHG emission action plans to address the unique climate risks and decarbonization opportunities of each location, increasing site ownership and contributing to global climate targets.
• The Company expanded its use of renewable energy through the commissioning of an 8.2- megawatt (“MW”) solar plant at the Masbate Gold Project that is expected to reduce GHG emissions by approximately 8,800 tonnes annually when fully operational. At the Fekola Complex, the expanded solar facility reached full operational capacity in January 2025, adding 22 MW of solar capacity (for a total capacity of 52 MW). The expanded facility supplied approximately 23% of the site’s total electricity demand in 2025.
• B2Gold’s consolidated Scope 1 and 2 GHG emissions increased to an estimated 757 thousand tonnes CO₂e compared to 699 thousand tonnes in 2024, due to the addition of the Back River Gold District. Total Scope 1 and 2 GHG emissions for Fekola, Masbate and Otjikoto were an estimated 673 thousand tonnes of CO₂e in 2025 (compared with 699 thousand tonnes in 2024 for our Fekola, Masbate and Otjikoto operations). The Company’s consolidated GHG emissions intensity was 0.77 tonnes CO₂e per gold ounce produced in 2025 (compared with 0.89 in 2024), a modest decrease driven primarily by an increase in total gold production.
• The proportion of electricity consumed at B2Gold operations from renewable sources was 25% in 2025 (compared with approximately 22% in 2024). At Otjikoto, the proportion of electricity consumed from renewable sources was approximately 79%.
