News Release

B2Gold Corp. Announces Positive Results from the

Expansion Study at El Limon Mine in Nicaragua and that a Renewed Collective Agreement has been

Signed with El Limon Labour Unions

Vancouver, October 22, 201 8 – B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G)

("B2Gold" or the "Company") is pleased to announce positive results of an expansion study for El Limon Mine

located in Nicaragua and that the Company has signed a renewed two-year Collective Agreement with the

labour unions.

The expansion study was conducted to evaluate the life-of-mine ("LoM") options for combining the remaining

underground Inferred Mineral Resources with the new El Limon Central zone open-pit Inferred Mineral

Resource. The results of this study recommend the expansion of the existing plant from 485,000 tonnes per

annum ("tpa") to 600,000 tpa and addition of a third stage of milling to achieve a fine grind. The result would

be a much longer mine life with significantly higher gold production and lower cash operating costs (see non-

IFRS Measures) and all-in sustaining costs ("AISC") (see non-IFRS Measures). The third stage of milling also

allows for the re processing of old tailings at the end of the mine life. All dollar figures are in United States

dollars unless otherwise indicated.

Highlights of El Limon Expansion Study Results

• Projected annual processing rate increase to 600,000 tpa

• LoM is estimated to be extended over 10 years, based on Inferred Mineral Resources from open pit and

underground sources with an additional 11+ years by processing historic mine tailings

• Estimated significant increase in average annual gold production to approximately 75,000 ounces per

year during approximately 10 years of mining. In addition, production would average over 18,000

ounces of gold per year for 11+ years when subsequently processing tailings from historic high-grade

mining

• Projected total gold production over 10 years of mining approximately 750,000 ounces of gold

• Projected total gold production of approximately 985,000 ounces of gold over 21+ years

• Lower estimated average direct cash operating costs per ounce below $600 and reduced projected AISC

of approximately $900 per ounce of gold (excluding expansion capital costs)

• Estimated expansion capital cost of approximately $35 million over a period of approximately 16 months

for plant upgrades and expansion

• Forecast LoM after-tax net cash flow of over $235 million at a gold price of $1,300 per ounce

• Forecast after-tax net present value of over $135 million at a 5.0% discount rate and gold price of

$1,300 per ounce, generating an after-tax internal rate of return of approximately 28%

• Ongoing drilling continues to extend El Limon Central zone to the north. Mineralization remains open to

the north and at depth

Project Size Trade-off Studies

El Limon expansion study was evaluated at throughput rates ranging from 500,000 t pa to 1,100,000 t pa.

Metallurgical test results indicate that the existing plant could be expanded to a production level of 600,000

tpa by upgrading the crushing system, adding a pebble crusher, adding a new thickener, and upgrading the

cyclones and leach circuit. Expansion to 1,100,000 tpa would require an upgrade of the existing plant as well

as the construction of a new 500,000 tpa plant.

Metallurgical testing was also completed to evaluate the optimum grind size for both El Limon Central ore

and the Santa Pancha underground ore sources. Results indicate that there would be a significant improvement

in recovery for El Limon Central pit ore and also an improvement for the Santa Pancha recoveries at finer

grind sizes (80% passing 30 microns). The finer grind would be achieved by adding a third stage of grinding

to the milling circuit. The fine grind capability would also allow for the retreatment of old tailings at the end

of the mine life with only minor plant modifications. High-level production scenarios, capital cost estimates

and operating cost estimates were developed for various cases ranging from 500,000 tpa to 1,100,000 tpa

with both coarse and fine grinding.

According to the study, the 600,000 tpa fine grind case with the processing of old tailings ("600FwT") would

result in the best current project economics. The significant additional capital costs associated with building

a second new plant for the 1 million + tpa cases are not justifiable based on the existing Inferred Mineral

Resource. However, these cases may become viable as future further expansion opportunities if the Mineral

Resource is expanded by further positive drilling results . El Limon Central zone mineralization continues to

be extended to the north by drilling, and remains open to the north and at depth.

The 600FwT expansion would consist of upgrading the crushing system, installing a pebble crusher in the

SAG mill circuit, adding a third stage of grinding, replacing the pre-leach thickener, adding power generating

capacity and making improvements to the gold recovery circuits. The initial capital cost estimates for these

improvements would be approximately $35 million. It has been assumed that open -pit mining will be done

by contract mining using establis hed contactors. The study assumes the processing of old tailings will begin

after the underground and open-pit resources have been depleted.

Basis of the Study

In February 2018, the Company announced a positive initial open-pit Inferred Mineral Resource at the newly-

discovered El Limon Central zone at El Limon property in Nicaragua of 5,130,000 tonnes at a grade of 4.92

grams per tonne ("g/t") of gold containing 812,000 ounces of gold (see news release dated 02/23/2018). This

resource has provided the open-pit resources for the expansion study. Total Inferred Mineral Resources from

underground and open-pit sources included in this study consist of approximately 6.0 million tonnes at a grade

of 4.3 g/t, containing approximately 829,000 ounces. Mineral Resources that are not Mineral Reserves do not

have demonstrated economic viability.

A consistent mix of underground and open -pit ore feeding the plant has always provided the optimum

operating conditions for El Limon Mine, and the new Mineral R esources at El Limon Central zone will

3

provide long term, open-pit feed to blend with the underground ore. Approximately 60% of the plant feed is

planned to come from open pits which have an overall strip ratio in the range of 16 tonnes of waste to 1 tonne

of mill feed. At the end of the mine life , plant feed is expected to come from the old tailings at a rate of

600,000 tpa.

Processing of historic tailings is based on a n Indicated Mineral Resource estimate containing 7.3 million

tonnes of historic tailings at average grades of 1.12 g/t gold and 4.1 7 g/t silver, containing approximately

263,000 ounces of gold and 982,000 ounces of silver. Of that resource, approximately 6.9 million tonnes was

included in the study at gold and silver grades of 1.15 g/t and 4.11 g/t, respectively, containing approximately

255,000 ounces of gold and 916,000 ounces of silver. Annual production rates during the processing of the

tailings from historic high -grade mining are estimated to average over 18,000 ounces of gold and 64,000

ounces of silver. Cash operating costs per ounce and AISC per ounce for the processing of the old tailings are

forecast to be slightly lower compared to processing the open pit and underground ore resources.

Upside Potential

Positive drilling results continue to expand El Limon Central zone to the north, indicating the potential to

expand the Mineral Resources. The zone is also open to depth, indicating the potential to produce ore from

underground in El Limon Central area once open -pit mining is completed.

B2Gold’s technical team is currently updating El Limon Inferred Mineral Resource to include recent

additional drilling results and conducting mine optimization studies with a view to potential ly improve the

positive economics for El Limon expansion. These studies are expected to be completed in the first quarter

of 2019.

Renewed Collective Agreement with El Limon Mine Union Workers

Today, representatives of B2Gold Management and the Labour Unions at El Limon Mine renewed the

existing Collective Agreement for two years. The renewal ensures the continuance of stable labour relatio ns

and coincides with the positive news regarding the long -term prospects of El Limon Mine.

Cautionary Statement

The reader is advised that the results summarized in this news release are intended to provide only an initial, high -level

review of the project potential and expansion options. The initial mine plans and economic models include numerous

assumptions and the use of Inferred Mineral Resources. The expansion study is preliminary in nature, and it includes

Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied

to them that would enable them to be categorized as Mineral Reserves. There is no guarantee that Inferred Mineral

Resources can be converted to Indicated or Measured Mineral Resources and, consequently, there is no guarantee the

production estimates or project economics described herein will be achieved.

Non-IFRS Measures

This news release includes certain terms or performance measures commonly used in the mining industry that are not

defined under International F inancial 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 B2G old’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.

Cautionary Note to United States Investors

The disclosure in this news release was prepared in accordance with Canadian National Instrument 43 -101 ("NI 43 -

101"), which differs significantly from the 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 U.S.

standards. In particular, this news release refers 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. inv estors 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 unde r 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" determi nation is made. Further, while

NI 43 -101 permits companies to disclose economic projections contained in pre -feasibility studies and preliminary

economic assessments, which are not based on "reserves", U.S. companies are not normally permitted to disclose

economic projections for a mineral property in their SEC filings prior to the establishment of "reserves". 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 gre at 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 Ca nadian reporting standards; however, the SEC normally only

permits issuers to report mineralization that does not constitute "reserves" by SEC 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.
