B2Gold Announces Positive Initial Open-pit Resource at the Newly-discovered

El Limon Central Zone, Nicaragua

Vancouver, February 23, 2018 – B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G) (“B2Gold”

or the “Company”) announces a positive initial open-pit resource at the newly-discovered El Limon Central zone,

at the El Limon property in Nicaragua, of 5,130,000 t onnes at a grade of 4.92 grams per tonne (“g/t”) of gold

containing 812,000 ounces of gold (refer to table below). This large, good grade new zone has the potential to

decrease the El Limon Mine’s cash operating costs and all-in sustaining costs per ounce, dramatically increase the

El Limon mine life, and could lead to an expansion of the El Limon mill to a higher throughput rate which could

potentially double annual gold production.

The El Limon Central zone, at its closest location, is approximately 150 metres from the El Limon mill facility,

extending southeast and northwest, adjacent to existing plan t and administrative infrastructure. Historical records

indicate that parts of the Central zone had been mined underground in past decades. B2Gold’s recent exploration

work indicates the underground mining was much more limited than previously thought.

The El Limon central vein structure has been drill tested along a 2.2-kilometre strike length so far, and remains

open to depth and along strike, and will be further drill tested during 2018. This structure has experienced some

limited historic mining along its length. Further north, the structure extends along strike and this area is being drill

tested at present.

Highlighted results within the pit include 19.70 metres at 24.24 g/t gold (LIM-17-4119), 24.80 metres at 11.65 g/t

gold (LIM-17-4112), 5.66 metres at 64.76 g/t gold (LIM -16-3984) and 15.70 metres at 20.04 g/t gold (LIM-17-

4069).

Below, and beyond, the resource pit limits to the north, drill highlights include 2.0 metres at 13.43 g/t gold (LIM-

17-4184) and 20.35 metres at 3.0 g/t gold, including 4.1 metres at 6.85 g/t gold (LIM-17-4198). All widths noted

are true widths.

The Mineral Resource estimate was prepared in-house at B2Gold. A total of 248 drill holes (35,871 metres of

drilling) were used in the gold grade estimate with mo re than 75% of the drill meterage (28,078 metres) coming

from diamond drilling, completed by B2Gold. The remainde r of the drilling was completed by previous owners

during the late 1990s through early 2000s.

1.Mineral Resources are reported in accord ance with NI 43-101 and the 2014 Canadian Ins titute of Mining, Metallurgy and Petrole um “Definition

Standards for Mineral Resources and Mineral Reserves” (CIM Definit ion Standards). Mineral Resources that are not Mineral Reserv es do not have

demonstrated economic viability

Inferred Mineral Resources are amenable to open-pit mini ng methods and are reported within a pit shell run using

a gold price of US$1,400/oz., an average gold recovery of 83.8% (based on preliminary metallurgical testwork),

and recent EL Limon Mine cash operating costs.

The 2017 El Limon budget was increased to USD$7.00 million and included over 30,000 metres of drilling in 157

holes with a focus on the El Limon vein. The 2018 El Limon budget is USD$7.00 million and will include 24,900

metres in 132 holes, again, with a focus on the El Limon vein.

B2Gold is currently conducting add itional metallurgical testing on the El Limon Central ore and a study to

evaluate the potential to expand the El Limon throughput to significantly increase annual gold production and

reduce cash operating costs. The study is expected by mid-2018.

El Limon Tailings Project Update

In 2017, an initial study was completed regarding the pot ential re-processing of the old tailings at the El Limon

Mine. Based on historic mill and drilling records, the taili ngs contain an estimated 9 million to 11 million tonnes

with a potential gold grade of 0.80 g/t to 1.0 g/t. An o ngoing drilling program is underway as part of a feasibility

study which will confirm resources and grades, the optimum grind size, capital costs and final project economics.

Based on the initial study completed in 2017, the Company believes that the project has the potential to produce

an average of approximately 20,000 to 25,000 ounces of gold and 70,000 to 80,000 ounces of silver per year for

approximately 9 to 11 years. The concep t is to regrind the old tailings to a much finer grind size, process them

through a new CIP plant and place the tailings in a new lin ed tailings storage facility. The potential quantity and

grade included in the initial study is conceptual in nature , and there has been insufficient exploration to date to

define a Mineral Resource, and it is unc ertain if further exploration will result in the target being delineated as a

Mineral Resource.

The El Limon Mine has produced over 3 million ounces of gold since 1941, principally from the veins of El

Limon, Talavera and Santa Pancha, the current focus of production. B2Gold purchased the mine in 2009, with the

acquisition of Central Sun Mining, and the 19,200-hectare El Limon Mine is 95% B2Gold and 5% IMISA. The

2018 production forecast is between 55,000 to 60,000 ounces of gold.

B2Gold’s Quality Assurance/Quality Control

The primary laboratory for El Limon drilling program is Bureau Veritas Minerals in Vancouver, Canada. Core

samples are prepared at El Limon preparation facility with the pulp sent to Vancouver and analysed using 30g fire

assay with atomic absorption finish as well as multi-ele ment ICP-MS analyses. SGS Laboratories in Medellin,

Colombia, is the umpire laboratory.

Quality assurance and quality control procedures include the systematic insertion of blanks, standards and

duplicates into the core sample strings. The results of th e control samples are evaluated on a regular basis with

batches re-analysed and/or resubmitted as needed. All results stated in this announcement have passed B2Gold's

quality assurance and quality control ("QA/QC") protocols.

Tom Garagan, Senior Vice President of Exploration, is the Qualified Person as defined under National Instrument

43-101, who has reviewed and approved the contents of this news release.

Cautionary Note to United States Investors

The disclosure in this news release and in the documents described in this news release regarding mineral properties 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. Accord ingly, such disclosure may not be comparable to similar

information made public by companies that report in accordance with U.S. standards.

The Company has prepared its public disclosures in accord ance with Canadian securities laws, which differ in certain

respects from U.S. securities laws. In particular, this news release refers to “mineral res ources” and “inferred mineral

resources”. While these categories of mineralization are reco gnized 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” or “inferred mineral resource” will ever be converted into a

“reserve.” In addition, “reserves” reported by the Company und er 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 th e “reserve” determination is ma de. Accordingly, information

contained or referenced in this news release containing de scriptions 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 re gulations. “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 ca tegory. Historical results or feasibility models presented

herein are not guarantees or expectations of future performance.
