Bedrock drill holes MSD_127 (20.20 m at 6.05 g/t gold) and MSD_132 (24.50 m at 4.02 g/t gold) are indications of highly prospective structures beneath Anaconda and Mamba, respectively. The intersection in MSD_132 occurs approximately 160 metres down-dip from the saprolite-hosted intersection in MSR_360 (46 m at 1.94 g/t gold), suggesting there is significant down-dip continuity along this structure. Follow up drilling is currently underway in both target areas. These holes and other selected results from the recent bedrock drilling are presented by target area in the table below:

Note: Bedrock-hosted intervals reported above are >0.6 g/t gold, with a maximum of 5 m internal waste. Intervals reported are core lengths.

Drilling is ongoing to further test the Fekola North Extension zone, infill the Fekola resource, and further test the new bedrock mineralization beneath the Anaconda, Adder and Mamba saprolite resource. The Company is planning additional, aggressive exploration drilling programs on these targets in 2018.

Fekola Ramp Up and Gold Production

On September 25, 2017, the Company announced that it had completed construction of the Fekola mill on budget and commenced ore processing at the Fekola Mine, more than three months ahead of schedule. In September, Fekola produced 6,340 ounces of in-circuit gold inventory (nil ounces budgeted). Commissioning of the mill is ongoing and is expected to ramp up quickly to achieve commercial production by the end of November 2017, four months ahead of the original schedule and one month ahead of the revised schedule.

In October 2017, the first full month of ramp up and pre-commercial production, the Fekola mill produced a total of 33,946 ounces of gold in the month (budget of 15,100 ounces). For 2017, the Company is projecting gold production from Fekola to exceed the upper range of its reforecast production guidance range of between 50,000 and 55,000 ounces. 2018 is scheduled to be the first full year of gold production at Fekola, yielding 400,000 to 410,000 ounces for the year at a cash operating cost of approximately $354 per ounce of gold and AISC of $609 per ounce of gold.

Based on current assumptions and updates to B2Gold's current year guidance and long-term mine plans, the Company is projecting consolidated gold production in 2017 of between 530,000 and 570,000 ounces. In 2018, production is forecast to increase significantly to between 925,000 and 975,000 ounces with the inclusion of the anticipated first full year of commercial production at Fekola.

This news release 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, estimates and other statements regarding future financial and operational performance, events, production, costs, including projected cash operating costs and AISC, capital expenditures, budgets and growth, production estimates and guidance, including the Company's projected gold production of between 530,000 to 570,000 ounces in 2017 and between 925,000 and 975,000 ounces in 2018 and gold production at Fekola exceeding the upper range of its production guidance of between 50,000 to 55,000 ounces in 2017 and producing 400,000 to 410,000 ounces in 2018 at a cash operating cost of approximately $354 per ounce of gold and AISC of $609 per ounce of gold; and statements regarding anticipated exploration, development, construction, production, permitting and other activities and achievements of the Company, including but not limited to: achieving commercial production at the Fekola Mine by the end of November, 2017; mineralization in the upper portion of the Fekola North Extension zone being one continuous mineralized zone and the potential to increase the extent of Fekola mineralization; the potential to extend good grade mineralization much further north from the Fekola resource pit boundary; results indicating the deeper portion of the Fekola Northern Extension zone extending closer to surface and indicating continuity with mineralization from the deeper drilling results from the upper portion of the Fekola North Extension; the potential for additional large Fekola style mineralized zones; the potential for highly prospective structures beneath the Anaconda and Mamba zones; the resource pit extension containing 720,000 ounces in the indicated category and 280,000 ounces in the inferred category, for a total potential increase of 900,000 ounces of gold; the conversion of inferred mineral resources to indicated mineral resources; the projections included in existing technical reports, economic assessments and feasibility studies; the results of anticipated or potential new technical reports and studies, including the potential findings and conclusions thereof. 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 news release 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.

The list is not exhaustive of the factors that may affect the Company's forward-looking statements. There can be no assurance that such 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. The Company's forward-looking statements reflect current expectations regarding future events and operating performance and speak only as of the date hereof and the Company 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. The Company'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 the Company'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; the Company'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 obligations; 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. For the reasons set forth above, undue reliance should not be placed on forward-looking statements.

Non-IFRS Measures

This news release 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 reconciliation of certain measures to IFRS terms.

Cautionary Note to United States Investors

The Company has prepared its public disclosures in accordance with Canadian securities laws, which differ in certain respects from U.S. securities laws. In particular, this news release 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 the SEC 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, "reserves" reported by the Company under Canadian standards may not qualify as reserves under SEC standards. Under SEC standards, 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 news release containing descriptions of the Company's mineral deposits may not be compatible to similar information made public by U.S. companies subject to the reporting and disclosure requirements of U.S. federal securities laws, rules and regulations. "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. Historical results or feasibility models presented herein are not guarantees or expectations of future performance.
