B2Gold Reports Q2 2025 Results

Continued Strong Operating Performance Across All Three Operations Led to Higher Than Expected

Gold Production and Lower than Expected Cash Costs in the Second Quarter of 2025

Vancouver, BC, August 7, 2025 – B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G)

(“B2Gold” or the “Company”) is pleased to announce its operational and financial results for the second

quarter of 2025. All dollar figures are in United States dollars unless otherwise indicated.

2025 Second Quarter Highlights

• Gold production of 229,454 ounces: Consolidated gold production in the second quarter of 2025,

including pre-commercial production from the Goose Mine, was 229,454 ounces, higher than

expected. The Fekola, Masbate and Otjikoto mines all exceeded expected production in the second

quarter, and the Company remains on track to meet its consolidated annual production guidance

range. All three operations continue to meet or ex ceed gold production expectations to start the

third quarter of 2025.

• Consolidated cash operating costs of $745 per gold ounce produced : Consolidated cash

operating costs (see “Non-IFRS Measures”), excluding pre-commercial production from the Goose

Mine, were $745 per gold ounce produced ($762 per gold ounce sold) during the second quarter of

2025. Cash operating costs per ounce produced fo r the second quarter of 2025 were better than

expected as a result of lower than expected fuel costs and higher than expected gold production.

• Consolidated all-in sustaining costs of $1,519 per gold ounce sold: Consolidated all-in sustaining

costs (see “Non-IFRS Measures”) were $1,519 per gold ounce sold during the second quarter of

2025. Consolidated all-in sustaining costs for the second quarter of 2025 were higher than expected

as lower production costs per gold ounce sold and lower sustaining capital expenditures were offset

by higher gold royalties resulting from a higher than expected average realized gold price and lower

than expected ounces sold. The lower sales ounces were a result of the timing of shipments from

the Company's Masbate and Fekola Mines, which were delivered and sold in July 2025.

• Attributable net income of $0.12 per share; ad justed attributable net income of $0.12 per

share: Net income attributable to the shareholders of the Company of $154 million, or $0.12 per

2

share; adjusted net income (see “ Non-IFRS Measures ”) attributable to the shareholders of the

Company of $163 million, or $0.12 per share.

• Operating cash flow before working capital adjustments of $301 million : Cash flow provided

by operating activities before working capital and long-term value-added tax adjustments was $301

million in the second quarter of 2025.

• Strong financial position and liquidity : At June 30, 2025, the Company had cash and cash

equivalents of $308 million and working capital deficit (defined as cu rrent assets less assets

classified as held for sale and current liabilities) of $19 million. Working capital at June 30, 2025

reflects the classification of the Company’s gold pr epayment obligations as current liabilities. As

of June 30, 2025, the full amount of the Company's $800 million revolving credit facility (“RCF”)

was available for future draw downs.

• Inaugural gold pour achieved at the Goose Mine; ramp up to commercial production ongoing

and expected to be achieved in the third quarter of 2025; estimated gold production of 120,000

to 150,000 ounces in 2025: With first gold achieved, as announced on June 30, 2025, focus now

turns to continuing steady state operations and increasing throughput to full design capacity. The

Company continues to estimate that gold production in calendar year 2025 will be between 120,000

and 150,000 ounces and that averag e annual gold production for the six year period from 2026 to

2031 inclusive will be approximate ly 300,000 ounces per year, based only on existing Mineral

Reserves.

• Positive Feasibility Study on the Gramalote Pr oject in Colombia announced; after-tax NPV

(5%) of $941 Million with an after-tax IRR of 22.4% at a $2,500 per ounce gold price: On July

14, 2025, B2Gold announced positive Feasibility Study (“FS”) results on the Company’s 100%

owned Gramalote Project. The FS for the Gramalote project indicates an initial life of project of 13

years, with average annual production of 227,000 ounces over the first five years. Based on the

project economics, B2Gold has commenced the work of amendi ng the existing mine plan and

environmental permits which are currently in pl ace for a larger-scale project. B2Gold currently

anticipates the permit modification to the new me dium-scale project reflected in the current FS

could be completed over the next 12 to 18 months.

• Received approval to commence underground mining at Fekola: On July 30, 2025, the State of

Mali granted approval for the Company to commence underground mining at the Fekola Mine.

Subsequent to receipt of the approval, the Company commenced stope ore development and

production at the Fekola underground, and Fekola underground ore that was stockpiled during the

underground exploration development stage is currently being processed through the Fekola mill.

• Fekola Mine reaches production mileston e of four million ounces of gold produced:

Subsequent to June 30, 2025, the Fekola Mine achieved lifetime production of four million ounces

of gold, seven years and ten months from construction completion.

3

• New Board of Director appointment: On August 6, 2025, Mary-Lynn Oke, CPA, was appointed

to B2Gold's Board of Directors (the “Board”) . Ms. Oke brings extensive corporate finance

experience, and currently serves on the Boards of Directors of NexGold Mining Corp. and Jaguar

Mining Inc.

• Q3 2025 dividend of $0.02 per share declared: On August 7, 2025, B2Gold's Board of Directors

declared a cash dividend for the third quarter of 2025 of $0.02 per common share (or an expected

$0.08 per share on an annualized basis), payable on September 23, 2025, to shareholders of record

as of September 10, 2025.

specified, defined or determined under IFRS and presented in the Company’ s financial statements, refer to “Non-IFRS Measures”.

(3) Production from Calibre Mining Corp.'s ("Calibre") La Libertad, El Limon and Pan mines is presented on an approximate 24% b asis until January 24, 2024 and

14% subsequently until June 20, 2024 which represented the Company’ s indirect ownership interest in Calibre's operations through its equity investment in Calibre. On

June 20, 2024, the Company reduced its ownership interest to approximately 4% and determined that it no longer had significant influence over Calibre and as a result,

after June 20, 2024, no longer recorded attributable production representing its indirect ownership interest in Calibre's mines through an equity investment.

(4) Cash operating costs per gold ounce produced do not include the results of pre-commercial production from the Goose Mine. Pre-commercial production from the

Goose Mine in the second quarter of 2025 was not sold during the period. As a result, there is no impact to metrics on a per gold ounce sold basis.

Liquidity and Capital Resources

B2Gold continues to maintain a strong financial position and liquidity. At June 30, 2025, the Company had

cash and cash equivalents of $308 million (December 31, 2024 - $337 million) and working capital deficit

(defined as current assets less asset s classified as held for sale and current liabilities) of $19 million

5

(December 31, 2024 – surplus of $321 million). Working capital at June 30, 2025, reflects the classification

of the Company’s gold prepayment obligations as cu rrent liabilities. During the first half of 2025 the

Company repaid $400 million on the Company's $800 million revolving credit facility, leaving $800 million

remaining available for future draw downs, plus a $200 million accordion feature. Subsequent to June 30,

2025, on July 18, 2025, the Company drew down $200 million under the RCF which will be used to manage

working capital requirements during the Company's delivery of ounces into its gold prepayment obligations

over the 12-month period from July 2025 to June 2026.

Third Quarter 2025 Dividend

On August 7, 2025, the Board declared a cash dividend for the third quarter of 2025 (the “Q3 2025

Dividend”) of $0.02 per common share (or an expected $0.08 per share on an annualized basis), payable

on September 23, 2025 to shareholders of record as of September 10, 2025.

The Fekola Mine in Mali (owned 80% by the Company and 20% by the State of Mali) produced 126,361

ounces of gold in the second quarter of 2025, above expectations. For the second quarter of 2025, mill feed

grade was 1.84 grams per tonne ("g/t") gold, mill th roughput was 2.34 million tonnes, and gold recovery

averaged 91.2%.

The Fekola Mine’s cash operating costs (refer to “Non-IFRS Measures” ) for the second quarter of 2025

were $798 per ounce produced ($834 per gold ounce sold). Cash operating costs per ounce produced for

the second quarter of 2025 were lower than expected as a result of lower fuel costs, lower fleet maintenance

costs and higher gold production due to above expected mill feed grades.

All-in sustaining costs (refer to “Non-IFRS Measures” ) for the second quarter of 2025 were $1,721 per

gold ounce sold, higher than expected. All-in sustai ning costs for the second quarter of 2025 were higher

than anticipated as lower than e xpected production costs per gold ounce sold and lower than expected

sustaining capital expenditures were offset by higher gold royalties resulting from a higher than expected

average realized gold price and lower than expect ed gold ounces sold. Gold royalties include higher

revenue-based production taxes based on a sliding scale and revenue-based State of Mali funds applicable

7

for the Fekola Mine, which became effective for the first time in March 2025. The lower sustaining capital

expenditures for the second quarter of 2025 were mainly a result of timing of expenditures and are expected

to be incurred later in 2025. Lower than expected gold sales were a result of timing and these ounces were

shipped and sold in July 2025.

Capital expenditures in the second quarter of 2025 totalled $53 million primarily consisting of $22 million

for deferred stripping, $17 million for Fekola underground development, $10 million for mobile equipment

purchases and rebuilds and $4 million for the construction of a new tailings storage facility.

The Fekola Complex is comprised of the Fekola Mine (Medinandi permit hosting the Fekola and Cardinal

open pits and Fekola underground), owned 80% by B2 Gold and 20% by the State of Mali, and Fekola

Regional (Anaconda Area (formerly the three separ ate Bantako, Menankoto a nd Bakolobi permits, now

consolidated into one permit called Menankoto) an d the Dandoko permit), whic h will be owned 65% by

B2Gold and 35% by the State of Mali. Fekola Regiona l is located approximately 20 kilometers from the

Fekola Mine.

On July 30, 2025, the State of Mali granted a pproval for the Company to commence underground

operations, including stope ore production, at th e Fekola Mine ("Underground Mining Approval").

Throughout 2024 and 2025, the Company has been ca rrying out underground e xploration development

work at the Fekola Mine in anticipation of the receipt of Underground Mining Approval. This includes more

than 9,300 meters of development work plus th e installation of all required underground mining

infrastructure. Subsequent to receipt of the Underground Mining Approval, the Company commenced stope

ore production at Fekola underground, and Fekola underground ore that was stockpiled during the

underground exploration development stage is currently being processed through the Fekola mill. In 2025,

the Company anticipates Fekola underground to cont ribute between 25,000 to 35,000 ounces of gold

production, ramping up significantly in 2026 and subsequent years.

The development of Fekola Regional has the potential to enhance the Fekola Complex production profile

and extend the mine life. Fekola Regional is anticip ated to contribute approximately 180,000 ounces of

additional annual gold production in its first four fu ll years of production from 2026 through 2029, with a

mine life expected to extend well into the 2030’s. The Company and the State of Mali have committed to

work together to finalize the approval of the Fekola Regional exploitation permit in the near term, with

permit approval expected prior to the end of the th ird quarter of 2025. Importantly, the haul road from

Fekola Regional to the Fekola Mine is operational as construction of the haul roads and mining

infrastructure (warehouse, workshop, fuel depot and offices) was completed on schedule in 2023. Upon

issuance of the exploitation permits for Fekola Regi onal, mining pre-stripping activities will begin for a

period of three months, followed by initial gold production now expected to commence in late 2025.

Despite the delay in expected commencement of mini ng at Fekola Regional, the Company still expects to

meet its production guidance of between 515,000 an d 550,000 ounces from the Fekola Complex in 2025.

The Fekola Complex is projected to process 9.56 million tonnes of ore during 2025 at an average grade of

1.84 g/t gold with a process gold recovery of 93.4%. Gold production is expected to be weighted

approximately 40% to the first half of 2025 and 60% to the second half of 2025.

8

The Company has updated its cash cost and all-in sustaining cost guidance ranges for the Fekola Complex

to reflect the expected impact of lower than estimated fuel costs in 2025, and an increase in realized and

expected gold prices for 2025 compared to a budgeted gold price of $2,250 per ounce, along with expected

changes in the timing of receipt of the exploita tion permit for Fekola Regiona l. Cash operating cost

guidance for the Fekola Complex is now forecast to be between $740 and $800 per gold ounce (original

guidance range of between $845 and $905 per ounce) and all-in sustaining cost guidance for the Fekola

Complex is now forecast to be between $1,595 and $1,655 per ounce (original guidance range of between

$1,550 and $1,610 per gold ounce).

The Masbate Mine in the Philippines continued its strong performance with second quarter of 2025 gold

production of 50,738, above expectations. For the second quarter of 2025, mill feed grade was 0.93 g/t gold,

mill throughput was 2.19 million tonnes, and gold recovery averaged 77.8%.

The Masbate Mine's cash operating costs (see “Non-IFRS Measures”) for the second quarter of 2025 were

$801 per ounce produced ($864 per gold ounce sold). C ash operating costs per ounce produced for the

second quarter of 2025 were lower than expected as a result of higher than expected gold production as

well as lower operating costs primarily due to lower diesel and heavy fuel oil cost.

All-in sustaining costs (refer to “Non-IFRS Measures” ) for the second quarter of 2025 were $1,497 per

gold ounce sold. All-in sustaining costs for the second quarter of 2025 were higher than expected as lower

than expected production costs per gold ounce sold we re offset by lower than expected gold ounces sold

and higher gold royalties resulting from a higher than e xpected average realized gold price. Lower than

expected gold ounces sold during the second quarter of 2025 was due to the timing of shipments, which

were delivered and sold in July 2025.
