B2Gold Announces Positive Exploration Results from the Anaconda Area and the Fekola Deposit

and an Update on the Fekola Mine Expansion

Vancouver, September 16, 2019 – B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G)

(“B2Gold” or the “Company”) announces positive drill results fr o m t h e M a m ba z o n e w h i c h i s l o c a t e d

within the Anaconda area approximately 20 kilometres from the Fekola Mine, as well as positive infill drill

results from the Fekola mineral resource area and step out results north of the Fekola resource.

Highlights include:

 Extending the shallow, high-grade saprolite mineralized zone at Mamba by approximately 600

metres to more than one kilometre of strike length

 Discovery of a new wide good grade sulphide zone directly beneath the Mamba saprolite zone.

The sulphide zone is open down plunge to the south, indicating the potential for Fekola-type gold

deposits

 Successful infill drilling at the Fekola deposit completed, upgrade of the Inferred Mineral

Resource (19%) to Indicated status by the fourth quarter of 2019

 Step out drilling continues to extend the Fekola deposit further to the north, which remains open

Recent Exploration

Drilling in 2019 in Mali has been focused on increasing the Ana conda area saprolite resource, testing

mineralized zones beneath the shallow saprolite zones, infill d rilling the Inferred portion of the Fekola

Mineral Resource to Indicated status and expanding the Fekola d eposit further to the north. Based on

positive drill results, in July, the Company increased the 2019 exploration budget in Mali by $3 million to

$20.5 million.

Anaconda Area (see figure 1 “Mamba long section” below)

B2Gold has completed an 850-hole (24,863 metre) program of comb ined aircore, diamond and reverse

circulation drilling at the Anac onda area, including on the Com pany’s increased land position. Drilling

focused mainly on the Mamba zone, located one kilometre east of the Anaconda zone, where the Company

previously announced an Inferred Mineral Resource estimate of 7 67,000 ounces of gold at 1.1 grams per

tonne (“g/t”) in near-surface sap rolite mineralization over 4.5 kilometres and up to 500 metres wide. The

initial stage of the program has extended the strike length of known saprolite mineralized structures at

2

Mamba by over 600 metres to over approximately one kilometre. S aprolite mineralization at the Adder

zone, 1.2 kilometres to the west of the Mamba zone, remains ope n to the north. At Mamba, the newly

discovered wide zone of sulphide mineralization is contiguous a nd continuous with the saprolite

mineralization and remains open down plunge and to the south, indicating the potential to host Fekola-style

sulphide gold deposits.

Recent holes include BNR_010 (61 metres at 2.25 g/t gold from 30 metres) and BNR_005 (39 metres at

3.16 g/t gold from 77 metres) , which intersected thick accumulations of good grade saprolite

mineralization. Highlights from the sulphide-hosted mineralizat ion include BND_001, which intersected

38.40 metres at 2.40 g/t gold from 72.70 metres directly down plunge from the high-grade saprolite

mineralization and 13.95 metres at 2.20 g/t gold from 184.05 metres and hole BNR_002, which

intersected 14 metres at 4.50 g/t gold from 109 metres.

These new intersections occur approximately 150 metres up plung e from previous sulphide intercepts on

the Mamba zone, which include two holes on the same section: MSD_141(44.00 metres at 1.22 g/t gold

from 80.00 metres and 46.20 metres at 1.76 g/t gold from 168.80 metres) and the undercutting hole,

MSD_132 (23.22 metres at 1.31 g/t gold from 116.48 metres, 24.50 metres at 4.02 g/t gold from 218.50

metres and 22.80 metres at 1.04 g/t gold from 253.20 metres). The geometry of this good grade zone of

mineralization is to be confirmed with additional drilling.

Highlights from drilling to date include:

Fekola Infill Program (see figure 2 “Fekola long section” below)

In October 2018, B2Gold reported an updated Indicated Mineral R esource estimate of 92,810,000 tonnes

at 1.92 g/t gold for a total of 5,730,000 ounces of gold, and a n Inferred Mineral Resource estimate of

26,500,000 tonnes at 1.61 g/t gold for a total of 1,370,000 oun ces of gold (19%), for the Fekola Mine (see

news release dated October 25, 2018 ). A significant portion of the 2019 drilling has been focused on

upgrading the Inferred Mineral Resource estimate to Indicated s tatus, with a total of 25,000 metres

completed as of August 15, 2019.

Infill drill results to date support the results of the 2018 re source model, which had 19% Inferred Mineral

Resources and 81% Indicated Mineral Resources. Furthermore, dri ll holes FKD_409 (4.03 g/t gold over

30.50 metres from 437.5 metres), FKD_413 (10.44 g/t gold over 1 9.8 metres from 495.2 metres) and

FKD_415 (3.3 g/t gold over 38.2 metres from 467.5 metres) provide added confirmation that significant

intervals of high-grade gold mineralization occur beyond the li mits of the 2019 Preliminary Economic

Assessment (“PEA”) pit shell ( see news release dated May 13, 2019 ), within the deepest portions of the

2018 $1,400/ounce gold resource p it shell. Follow up drilling d own plunge from this good grade

mineralization has been completed and assays are pending from h oles FKD_431 and FKD_432.

Mineralization remains open to t he north and down plunge. An up dated resource model is scheduled for

completion the fourth quarter of 2019.

Ongoing Exploration

Drilling is ongoing at Fekola, including a reconnaissance progr am on the Cardinal zone, less than one

kilometre west of the Fekola Mine open pit. Drilling on the Ana conda area, to test the extension of the

saprolite zones and further explore the sulphide mineralization below is scheduled to recommence in the

fourth quarter of 2019. An additional 30,000 metres of drilling is planned for completion before year end

and the Company expects to continue with an aggressive exploration program in 2020.

Fekola Mine Expansion Update

On March 26, 2019, B2Gold announced positive results from the E xpansion Study PEA for the Fekola

Mine. As a result, the Company is proceeding with an expansion project to increase processing throughput

by 1.5 million tonnes per annum (“Mtpa”) to 7.5 Mtpa from an as sumed base rate of 6 Mtpa. The PEA

reflected the significant increase in the Fekola Mineral Resource estimate announced on October 25, 2018.

Based on the PEA, once this expansion is complete, the Fekola Mine is expected to produce more gold over

a longer life, with more robust economics and higher average an nual gold production, revenues and cash

flows than the previous life-of-mine (“LoM”).

Highlights from the PEA include: estimated optimized LoM extend ed into 2030, including significant

estimated increases in average annual gold production to over 550,000 ounces per year during the five-year

period 2020-2024 and over 400,000 ounces per year over the LoM (2019-2030), projected gold production

of approximately five million ounces over the new mine life of 12 years of mining and processing (including

2019).

The processing upgrade at the Fekola Mine will focus on increased ball mill power, with upgrades to other

components including a new cyclone classification system, pebbl e crushers and additional leach capacity

to support the higher throughput and increase operability. Crit ical path items include ball mill motors and

the lime slaker, both of which the Company expects to be commis sioned in the third quarter of 2020. In

parallel with the expansion, B2Gold has initiated the detailed engineering and construction for the addition

of a 30-megawatt solar power plant, which the Company expects will result in reduced operating costs and

greenhouse gas emissions. Completion of the solar plant is sche duled for the third quarter of 2020. The

current on-site power plant has sufficient capacity to support the expanded processing throughput, with or

without the solar plant.

Construction will commence in Oct ober 2019 and is scheduled to be completed by the end of July 2020.

All major long-lead equipment has been ordered. Detailed engineering and design activities are progressing

well and scheduled to be completed by October 2019.

Based on B2Gold’s current projections, gold production at the F ekola Mine in 2020 is projected to be

approximately 600,000 ounces of gold, primarily due to the addition of a larger mining fleet at Fekola and

the optimization of the mining sequence early in 2020, prior to completion of the mill expansion by

September 2019, providing access to higher grade portions of the deposit earlier on in the sequence.

Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The

Expansion Study PEA is preliminary in nature and includes Indic ated and Inferred Mineral Resources.

Inferred Mineral Resources are considered too speculative geolo gically to have economic considerations

applied to them that would enable them to be categorized as Min eral Reserves. Consequently, there is no

certainty that the Expansion Study PEA will be realized.
