CAUTIONARY STATEMENT

2

Tom Garagan, Senior Vice President of Exploration, a Qualified Person as defined by National Instrument 43-101, has approved the scientific and technical information concerning B2Gold Corp. ("B2Gold") discussed in this presentation. All amounts in this presentation are expressed in U.S. dollars, unless otherwise stated. Production results and production guidance presented in this presentation reflect the total production at the mines B2Gold operates on a 100% basis. Please see in conjunction our Annual Information Form, dated March 23, 2018 and our Management Discussion and Analysis dated November 6, 2018 for a discussion of our ownership interest in the mines B2Gold operates. This presentation includes certain "forward-looking information" and "forward-looking statements" (collectively "forward-looking statements") within the meaning of applicable Canadian and United States securities legislation, including: projections; outlook; guidance; forecasts; estimates; and other statements regarding future or estimated financial and operational performance events, gold production and sales, revenues and cash flows, capital and operating costs, including projected cash operating costs and all-in sustaining costs ("AISC"), and budgets; statements regarding future or estimated mine life, metal price assumptions, ore grades or sources, stripping ratios, throughput, ore processing; statements regarding anticipated exploration, drilling, development, construction, permitting and other activities or achievements of B2Gold; and including, without limitation: B2Gold expecting to be at the lower end of its cost guidance range for consolidated cash operating costs and consolidated AISC for the full year 2018; gold production for 2019 being expected to be weighted towards the second half of 2019; results of the Optimizing Fekola Expansion Study being expected by the end of Q1 2019, such study including mine equipment configuration, mine scheduling and evaluation of dynamic cut off grades, ore stockpiling, blending and processing, and such study examining various throughput scenarios to maximize NPV including fleet sizing, mill expansion capital and

  • perating cost budgets and project economics and schedule; additional process upgrades being required at the Fekola Mine; the Fekola mill expansion having an estimated capital costs of approximately $50 million; the Masbate mill expansion being underway, the expected timing of such expansion

being in operation, and the effects thereof; and the El Limon optimizing studies being completed and such being expected to be complete in Q1 2019. Estimates of mineral resources and reserves are also forward-looking statements because they constitute projections regarding the amount of minerals that may be encountered in the future and/or the anticipated economics of production, should a production decision be made. All statements in this presentation that address events or developments that we expect to occur in the future are forward-looking statements. Forward-looking statements are statements that are not historical facts and are generally, although not always, identified by words such as "expect", "plan", "anticipate", "project", "target", "potential", "schedule", "forecast", "budget", "estimate", "intend" or "believe" and similar expressions or their negative connotations, or that events or conditions "will", "would", "may", "could", "should" or "might" occur. All such forward-looking statements are based on the opinions and estimates of management as of the date such statements are made. Forward-looking statements necessarily involve assumptions, risks and uncertainties, certain of which are beyond B2Gold's control, including risks associated with or related to: the volatility of metal prices and B2Gold's common shares; the dangers inherent in exploration, development and mining activities; the uncertainty of reserve and resource estimates; not achieving production, cost or other estimates; actual production, development plans and costs differing materially from the estimates in B2Gold's feasibility studies; the ability to obtain and maintain any necessary permits, consents or authorizations required for mining activities; the current ongoing instability in Nicaragua and the ramifications thereof; environmental regulations or hazards and compliance with complex regulations associated with mining activities; the ability to replace mineral reserves and identify acquisition

  • pportunities; the unknown liabilities of companies acquired by B2Gold; the ability to successfully integrate new acquisitions; fluctuations in exchange rates; the availability of financing; financing and debt activities, including potential restrictions imposed on B2Gold's operations as a result thereof and

the ability to generate sufficient cash flows; operations in foreign and developing countries and the compliance with foreign laws, including those associated with operations in Mali, Namibia, the Philippines, Nicaragua and Burkina Faso and including risks related to changes in foreign laws and changing policies related to mining and local ownership requirements; remote operations and the availability of adequate infrastructure; fluctuations in price and availability of energy and other inputs necessary for mining operations; shortages or cost increases in necessary equipment, supplies and labour; regulatory, political and country risks, including local instability or acts of terrorism and the effects thereof; the reliance upon contractors, third parties and joint venture partners; the lack of sole decision-making authority related to Filminera Resources Corporation, which owns the Masbate Project; challenges to title or surface rights; the dependence on key personnel and the ability to attract and retain skilled personnel; the risk of an uninsurable or uninsured loss; adverse climate and weather conditions; litigation risk; competition with other mining companies; changes in tax laws; community support for B2Gold's operations, including risks related to strikes and the halting of such operations from time to time; conflicts with small scale miners; failures of information systems or information security threats; the final outcome of the audit by the Philippines Department of Environment and Natural Resources in relation to the Masbate Project; the ability to maintain adequate internal controls over financial reporting as required by law, including Section 404 of the Sarbanes-Oxley Act; compliance with anti-corruption laws; as well as other factors identified and as described in more detail under the heading "Risk Factors" in B2Gold's most recent Annual Information Form, B2Gold's current Form 40-F Annual Report and B2Gold's other filings with Canadian securities regulators and the U.S. Securities and Exchange Commission, which may be viewed at www.sedar.com and www.sec.gov, respectively (the "Websites"). The list is not exhaustive of the factors that may affect B2Gold's forward-looking statements. B2Gold's forward-looking statements are based on the applicable assumptions and factors management considers reasonable as of the date hereof, based on the information available to management at such time. These assumptions and factors include, but are not limited to, assumptions and factors related to B2Gold's ability to carry on current and future operations, including: development and exploration activities; the timing, extent, duration and economic viability of such operations, including any mineral resources or reserves identified thereby; the accuracy and reliability of estimates, projections, forecasts, studies and assessments; B2Gold's ability to meet or achieve estimates, projections and forecasts; the availability and cost of inputs; the price and market for outputs, including gold; the timely receipt of necessary approvals or permits; the ability to meet current and future

  • bligations; the ability to obtain timely financing on reasonable terms when required; the current and future social, economic and political conditions; and other assumptions and factors generally associated with the mining industry.

B2Gold's forward-looking statements are based on the opinions and estimates of management and reflect their current expectations regarding future events and operating performance and speak only as of the date hereof. B2Gold does not assume any obligation to update forward-looking statements if circumstances or management's beliefs, expectations or opinions should change other than as required by applicable law. There can be no assurance that forward-looking statements will prove to be accurate, and actual results, performance or achievements could differ materially from those expressed in, or implied by, these forward-looking statements. Accordingly, no assurance can be given that any events anticipated by the forward-looking statements will transpire or occur, or if any of them do, what benefits or liabilities B2Gold will derive therefrom. For the reasons set forth above, undue reliance should not be placed on forward-looking statements. Non-IF IFRS RS Measures es This presentation includes certain terms or performance measures commonly used in the mining industry that are not defined under International Financial Reporting Standards ("IFRS"), including "cash operating costs" and "all-in sustaining costs" (or "AISC"), . Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. The data presented is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS and should be read in conjunction with B2Gold's consolidated financial statements. Readers should refer to B2Gold's Management Discussion and Analysis, available on the Websites, under the heading "Non-IFRS Measures" for a more detailed discussion of how B2Gold calculates such measures and a reconciliation of certain of such measures to IFRS terms. Cautio tiona nary Note to to United ted States tes Investo tors The disclosure in this presentation was prepared in accordance with Canadian National Instrument 43-101 ("NI 43-101"), which differs significantly from the current requirements of the SEC set out in Industry Guide 7. Accordingly, such disclosure may not be comparable to similar information made public by companies that report in accordance with Industry Guide 7. In particular, this news presentation may refer to "mineral resources," "measured mineral resources," "indicated mineral resources" or "inferred mineral resources". While these categories of mineralization are recognized and required by Canadian securities laws, they are not recognized by Industry Guide 7 and are not normally permitted to be disclosed in SEC filings by U.S. companies. U.S. investors are cautioned not to assume that any part of a "mineral resource," "measured mineral resource," "indicated mineral resource" or "inferred mineral resource" will ever be converted into a "reserve." In addition, this presentation uses the terms "reserves" and "probable mineral reserves" which are reported by B2Gold under Canadian standards and may not qualify as reserves under Industry Guide 7. Under Industry Guide 7, mineralization may not be classified as a "reserve" unless the mineralization can be economically and legally extracted or produced at the time the "reserve" determination is made. Accordingly, information contained or referenced in this presentation containing descriptions of B2Gold's mineral deposits may not be compatible to similar information made public by U.S. companies subject to the reporting and disclosure requirements of Industry Guide 7. "Inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian reporting standards; however, Industry Guide 7 normally only permits issuers to report mineralization that does not constitute "reserves" by Industry Guide 7 standards as in-place tonnage and grade without reference to unit measures. Historical results or feasibility models presented herein are not guarantees or expectations of future performance.

FEKOLA EXPANSION STUDY & OPTIMIZATION

Organic Growth

Preliminary expansion study completed1 The study evaluated the potential to expand the Fekola Mine and mill from the base case of 6 Mtpa of ore throughput to 7.5 Mtpa pa Results indicate robust economics for the 7.5 Mtpa pa expansion case with estimated process capital costs of $50 M Given the additional capacity of the Fekola primary crusher, SAG mill and other process systems, the study demonstrated that the 7.5 Mtpa pa upside can be achieved with an upgrade of the ball milli circuit as well as other equipment upgrades Based on the positive results of the preliminary Fekola expansion study, B2Gold has contracted Whittle Consulting to work together with B2Gold’s technical teams to conduct a study to optimize the Fekola expansion The study will evaluate:

  • Mining production rates
  • Pit and phase scheduling
  • Dynamic cut-off grades
  • Ore stockpiling, blending, dynamic processing and throughput recovery

The study will also examine various processing throughput scenarios to maximize project NPV, and the results will guide:

  • Mining equipment
  • Mill expansion
  • Project schedule decisions

Results of the optimized Fekola expansion study are expected to be released by the end of Q1 2019

PROBABLE MINERAL RESERVE ESTIMATES1

41

slide-42
SLIDE 42

1. Mineral Reserves have been classified using the CIM Standards. All tonnage, grade and contained metal content estimates have been rounded; rounding may result in apparent summation differences between tonnes, grade, and contained metal content. 2. Fekola Mine: Mineral Reserves are reported on an 80% attributable basis; B2Gold expects that the State of Mali will hold a 20% interest in the Fekola Mine. For further details of B2Gold’s interest in the Fekola Mine, see the heading “Material Properties – Fekola Mine – Property Description, Location and Access” in B2Gold’s Annual Information Form 2018. The Mineral Reserves have an effective date of December 31, 2017. The Qualified Person for the reserve estimate is Peter D. Montano, P.E., who is B2Gold’s Project Director. Mineral Reserves are based on a conventional open pit mining method, gold price of US$1,250/oz, metallurgical recovery of 93%, and average operating cost estimates of US$2.65/t mined (mining), US$15.81/t processed (processing) and US$3.13/t processed (general and administrative). Reserve model dilution and ore loss was applied through whole block averaging such that at a 0.8 g/t Au cutoff there is a 2.8% increase in tonnes, a 3.1% reduction in grade and 0.5% reduction in ounces when compared to the Mineral Resource model. An additional 5% dilution and 2% ore loss was applied during pit optimization and scheduling. Mineral Reserves are reported above a cutoff grade of 0.8 g/t Au. 3. Masbate Gold Project: Mineral Reserves are reported on a 100% attributable basis. Pursuant to the ore sales and purchase agreement between Filminera Resources Corporation (“Filminera”) and Philippine Gold Processing & Refining Corporation (“PGPRC”), B2Gold’s wholly-owned subsidiary, PGPRC has the right to purchase all ore from the Masbate Gold Project. The Mineral Reserves have an effective date of December 31, 2017. The Qualified Person for the reserve estimate is Kevin Pemberton, P.E., who is B2Gold’s Chief Mine Planning Engineer. Mineral Reserves are based on a conventional open pit mining method, gold price of US$1,250/oz, modeled metallurgical recovery (resulting in average LoM metallurgical recoveries by pit that range from 65% to 82%), and operating cost estimates of US$1.50/t-$1.60/t mined (mining), a variable ore differential cost by pit (average cost is US$0.17), US$8.45/t processed (processing) and US$2.50–3.83/t processed (general and administrative). Dilution and ore loss were applied through block averaging such that at a cutoff of 0.49 g/t Au, there is a 7% increase in tonnes, a 6% reduction in grade and no change in ounces when compared to the Mineral Resource model. Mineral Reserves are reported at cutoffs that range from 0.44–0.52g/t Au. 4. Otjikoto Mine: Mineral Reserves for Otjikoto and Wolfshag are reported on a 90% attributable basis; the remaining 10% interest is held by EVI Mining (Proprietary) Ltd., a Namibian empowerment company (“EVI EVI”). The Mineral Reserves have an effective date of December 31, 2017. The Qualified Person for the reserve estimate is Peter Montano, P.E., who is B2Gold’s Project Director. Mineral Reserves that will be mined by open pit methods assume a gold price of US$1,250/oz, metallurgical recovery of 98%, and operating cost estimates

  • f US$1.79/t mined (mining), US$12.27/t processed (processing) and US$3.67/t processed (general and administrative). Dilution and ore loss was applied through block averaging such that at a cutoff of 0.45 g/t Au, there is a 1% decrease in tonnes, a 4% reduction in
