News Release

B2Gold Announces Positive Exploration Drilling Results from its Inaugural Drilling Campaign at the Back

River Gold District in Nunavut and Provides an Update on Construction and Mining at the Goose Project

Vancouver, BC, November 21, 2023 – B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G)

(“B2Gold” or the “Company”) is pleased to announce positive exploration drilling results from its inaugural

drilling campaign at the Back River Gold District in Nunavu t and provide an update on construction and

mining at the Goose Project.

Exploration and Infill Drill Results Highlights

• 23,605 meters (“m”) drilled in 77 holes as of the end of October 2023, with results received

from 42 of the 77 holes

• Exploration d rilling i ntersected high-grade mineralization 1 10 m down plunge from the

existing mineral resource boundary at the Goose Project’s Llama deposit

o Drill hole 23GSE-626 returned 7.79 grams per tonne (“g/t”) over 22.00 m from 729.00 m,

including a higher grade interval of 11.22 g/t over 14.40 m, at a vertical depth of 660 m,

which tested a folded part of the structure 110 m down plunge from previous legacy

drilling; and

o This result demonstrates the continuity of gold grades and widths of these mineralized

structures, and the Llama deposit remains open at depth.

• Drill results for infill and mine development, received to date on the Goose Project’s Umwelt

deposit confirm the continuity of high-grade mineralization, with several drill holes returning

intercepts with higher gold grades and widths than predicted by the mineral resource model

o Drill hole 23GSE-618 returned 14.28 g/t gold over 16.00 m from 248.00 m;

o Drill hole 23GSE-620 returned 10.20 g/t gold over 19.00 m from 274.00 m;

o Drill hole 23GSE-622 returned 17.14 g/t gold over 17.05 m from 191.00 m;

o Drill hole 23GSE-625B returned 11.24 g/t gold over 24.15 m from 188.85 m; and

o The results from these drill holes will be included into the upcoming Goose Project

optimized life of mine plan.

In the second quarter of 2023, B2Gold approved a US$20 million exploration budget for the balance of

2023 to complete approximately 25,000 m of drilling on the Back River Gold District, significantly higher

than historical annual exploration expenditures. Drilling at the Goose Project began in early August 2023

2

with two drill rigs, testing the Llama deposit down -plunge for mineral resource confirmation and mineral

resource expansion, and testing regional targets that were deve loped based on structural modelling and

geophysical re-processing. The objective for drilling at the George Project was to test several targets over

a strike length of 10 kilometers (“km”).

As of the end of October 2023, B2Gold had completed 17,595 m of drilling over 51 drill holes on the Goose

Project, and a further 6,010 m of drilling over 26 drill holes on the George Project.

Figure 1. Back River Gold District Overview.

Goose Project Exploration

The Goose Project consists of five known deposits with existing mineral resources, Umwelt, Llama, Goose,

Echo and Nuvuyak, which occur along a strike length of 8 km. The Company believes that exploration

upside exists on all known deposits that are open at depth, as well as several zones of interest that remain

relatively untested within the footprint of the favorable host stratigraphy. Ongoing structural and data

review will form the basis of an aggressive 2024 exploration season to drill test several zones of interest.

As of October 31, 2023, a ssay results have been received from 16 of the 51 drilled holes at the Goose

Project.

At the Umwelt deposit, drilling was designed to confirm geometry and grade continuity of high -grade

shoots below the planned op en pit s. Results received to date confirm the continuity of high -grade

mineralization in the hinge and short limb of the Umwelt antiform and will provide critical information for

3

underground mine design planning. Since the end of October, a further 17 drill holes are planned for

completion in 2023.

At the Llama deposit, which outcrops 1,500 m north of the Umwelt deposit, two holes were drilled, which

have confirmed the extension of the structure at depth. Drill hole 23GSE-626 returned an impressive 7.79

g/t over 22.0 0 m from 729.00 m , including a higher grade intercept of 11.22 g/t over 14.40 m, and was

designed to test the favorable stratigraphy 660 m vertically , and 110 m down plunge beyond previously

reported inferred mineral resources. Drill hole 23GSE-614 returned high-grade narrow results on the less

drilled east limb of the Llama deposit including 32.75 g/t gold over 2.05 m from 365.95 m.

2. Drill intercepts are perpendicular to the zones so true widths are very similar to reported drill lengths

The Goose Project drill program will continue until mid -December 2023 to target high -grade plunging

shoots at Umwelt. The drill program in 2024 will start late in the first quarter of 2024 and focus on drilling

several zones on the Goose Project to expand known mineral resources and test new areas for mineral

resource upside potential.

George Project Exploration

At the George Project, loca ted 50 km northwest of the Goose Project, a 2023 spring and summer drill

program tested multiple targets along a 10 km strike length to evaluate mineralization controls and upside

potential with 6,010 m drilled over 26 drill holes.

The George Project represents three sub-parallel zones of tightly folded banded iron formation that stretch

over 20 km in strike length.

Drill results from the 2023 campaign reflect similar widths and grades as those reported by previous

operators, with several holes from the 2 023 program extend ing mineralization along strike and between

known zones of mineral resources. Drill hole 23GRL-216 returned encouraging results, intersecting 19.17

g/t gold over 7.50 m from 36.60 m, very close to surface between two known deposits (LCPS and LCPN).

In the southwestern part of the belt in the GH area, drill holes 23GRL -207 and 23GRL -211 extended

mineralization to the south of the existing mineral resource pit shell.

Quality Assurance/Quality Control on Sample Collection and Assaying

The primary laboratory utilized for the Back River Gold District drilling program in 2023 is ALS laboratory

in North Vancouver, Canada. Core samples are prepared at the ALS preparation facility in Yellowknife with

representative pulp samples sent to the ALS North Vancouver laboratory for gold analysis. Gold is analyzed

by a fire assay/atomic absorption s pectrometry (FA/AAS) finish using a 50 gram subsample of the coin

pulp. FAs were finished with AAS, and samples with higher grades that exceeded the maximum detection

limit of AAS received a supplemental gravimetric (“GRA V”) finish. All samples over 3,000 parts per billion

are analyzed by FA/GRA V using a 50 gram subsample of the coin pulp. Activatio n Laboratories Ltd.

(Actlabs) in Kamloops, Canada, is the umpire laboratory.

5

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

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

re-analyzed and/or resubmitted as needed. All results stated in this announcement have passed B2Gold’s

quality assurance and quality control protocols.

Goose Project, Nunavut, Construction and Mining Update

Construction at the Goose Project is progressing on track, with the project remaining on schedule for first

gold pour in the first quarter of 2025. Open pit mining is underway at the Echo Pit and underground

development work on the Umwelt deposit is ongoing.

The first concrete pour was completed in July 2023 and concrete and steel work in the mill area to date are

progressing ahead of schedule. Erection of the structural steel for the mill building, power house and truck

shop is well underway, and cladding is advancing quickly on the mill building with the roof complete and

over 50% of the building cladding completed. Cladding of both the power house and truck shop has begun.

Enclosure of these three buildings will allow for work to continue through the colder mont hs and remain

on schedule. Additionally, i t is expected that the ball mill will be set in place in December 2023,

approximately six months ahead of schedule, allowing the focus for the start of 2024 to shift to piping and

mechanical systems.

In July 2023, Phase 1 of the accommodation complex opened, including sleeping quarters, office area,

medical center, gymnasium, kitchens and water treatment. Phase 1 of the accommodation complex includes

310 beds at the permanent site location. In September 2023, the earthworks necessary to extend the airstrip

to 5,000 feet were completed. The extension of the airstrip will allow large capacity, fully loaded passenger

planes to land at the Goose Project throughout the 2024 construction campaign. In mid-October, the 2023

sealift was successfully completed , with a total of six ships received from global ports bringing a total

shipping volume of 90,000 cubic meters of dry cargo and 24,000,000 liters of arctic grade diesel fuel to the

Marine Laydown Area (“MLA”). The 2023 sealift included all planned material sealift materials required

for the successful construction, commissioning and mining of the Goose Project.

The 163 k m winter ice road (“WIR”) between the MLA and the Goose Project is scheduled to operate

between February and the end of April. The 2024 WIR construction team will mobilize to the MLA and

Goose Project sites in early and mid -December 2023, with the construction of the 2024 WIR expected to

begin in December 2023 . At the MLA, preparations for the 2024 WIR are well underway, including

maintenance and preparation of the WIR construction and haulage fleet and staging all materials for

shipment on the WIR to the Goose Project site.

Open pit mining of the Echo Pit is underway and will produce construction fill, stockpile ore and provide

tailings storage capacity. Open pit mining of the Umwelt Pit will commence in the first quarter of 2024 and

will produce much of the commissioning ore as well as future tailings storage. Underground development

of the Umwelt deposit is also underway, currently at a depth of 142 vertical meters below surface.

Breakthrough of the initial ventilation raise has been completed and development towards the ore zones is

in progress with more than 2,100 meters of lateral development completed to date.
