Management will host a conference call and webcast today, 31 July 2025, at 8:30 am EST / 1:30 pm BST. For instructions on how

to participate, please refer to the conference call and webcast section at the end of the news release. Copies of the Management

Report and Financial Statements have been submitted to the National Storage Mechanism and will be filed on SEDAR+. The

documents will shortly be available for inspection on the Company’s website and at:

https://data.fca.org.uk/#/nsm/nationalstoragemechanism.

Ian Cockerill, Chief Executive Officer, commented: "Q2-2025 has been another strong quarter for Endeavour, capping an excellent

first half of 2025 with 647koz of gold produced at an AISC of $1,281 per ounce; ensuring we are firmly on track to achieve ou r

full-year guidance.

As a result of our larger portfolio, following the completion of our growth phase 12 months ago, H1-2025 production was 38%

higher than the same period last year, with our all-in sustaining margin 80% higher, ensuring that we realised the full benefit of

the strong gold price environment.

Over the past 12 months, we have generated $879 million of free cash flow, equivalent to over $687 for every ounce of gold we

produced, or a yield of more than 17% from the start of the period. During H1, despite paying approximately 70% of our full -

year’s taxes, we still generated record free cash flow of $514 million, equivalent to $794 for every ounce of gold we produced,

and we are well positioned to continue delivering strong free cash flow in the second half of the year.

Underpinned by this strong free cash flow, we have maintained leverage well below our target and declared another record

dividend of $150 million for H1-2025, which we have further supplemented with $69 million of share buybacks, equivalent to

returns of $338 for every ounce of gold produced for the period. Since our first payments in 2021, we have returned $1.4 bill ion to

shareholders, over 80% above our minimum commitment, and equivalent to $213 for every ounce produced over the period.

Looking ahead, the DFS for our tier 1 Assafou project is on schedule for completion by early-2026, and the permitting process is

well advanced. Simultaneously, we are continuing to explore the property and expect to outline a resource update later this year,

incorporating resources from satellite discoveries in close proximity to Assafou.

We are very pleased with the operational performance we have delivered from our expanded portfolio and our ability to convert

that performance into cash flow. Our high-margin, long-life operations, coupled with our exciting organic growth pipeline

positions us well to continue delivering against our strategic objectives.”

OPERATING SUMMARY

• Strong safety performance for the Group, with a Lost Time Injury Frequency Rate (“LTIFR”) of 0.05 for the trailing twelve

months ended 30 June 2025.

• The Group remains on track to achieve its production guidance of 1,110 - 1,260koz, within its all -in sustaining cost (“AISC”)

guidance of $1,150 - 1,350/oz.

• H1-2025 production amounted to 647koz, an increase of 177koz over H1 -2024, due to higher average grades processed at

Houndé and Mana, and increased production at Lafigué and the Sabodala -Massawa BIOX expansion, which both entered

commercial production Q3-2024, partially offset by a decrease in production at Ity due to lower average grades processed.

• Q2-2025 production of 306koz was 36koz lower than Q1-2025, reflecting lower grades processed at Houndé, Mana and at the

Sabodala-Massawa CIL plant, in line with their mine sequences. This was partially offset by increased production at Lafigué

due to higher mill throughput, while production at Ity remained stable.

1Includes pre-commercial ounces that are not included in the calculation of All-In Sustaining Costs.

• H1-2025 total cash cost amounted to $1,064/oz, a decrease of $15/oz over H1 -2024, due to lower cash costs at the Houndé

mine related to a significant increase in gold sales and the addition of the low -cost Lafigué and Sabodala -Massawa BIOX

expansion, which both entered commercial production in Q3 -2024. The decrease was partially offset by higher royalty costs

across the portfolio, related to the higher realised gold prices.

• Q2-2025 total cash cost amounted to $1,220/oz, an increase of $291/oz over Q1 -2025 due to lower gold sales and higher

royalty costs related to the higher realised gold prices across the portfolio, as well as higher processing unit costs at Hou ndé

and Ity due to seasonally lower grid power availability, as hydroelectric dam capacity reached its lowest point for the year,

ahead of the annual wet season.

• H1-2025 AISC amounted to $1,281/oz, a slight increase of $44/oz over H1 -2024 due to higher royalty costs related to the

higher realised gold prices, higher sustaining capital due to the introduction of the Lafigué mine, at Ity related to

infrastructure and processing plant upgrades, at Sabodala -Massawa related waste stripping and at Mana related to

underground development.

• Q2-2025 AISC amounted to $1,458/oz, an increase of $329/oz over Q1-2025 driven by higher total cash costs including the

impact of higher royalty costs related to the higher realised gold prices, and higher sustaining capital at Houndé, Ity and

Lafigué, partially offset by lower sustaining capital at Sabodala-Massawa and Mana.

• H1-2025 and Q2 -2025 total cash costs and AISC have been impacted by higher sliding scale royalty costs due to higher

realised gold prices of $3,107/oz and $3,302/oz, exclusive of the impact of the revenue protection programme, respectively,

which are significantly higher than the $2,000/oz gold price assumption used in the FY -2025 guidance. As a result, higher

royalty costs related to gold price had an impact of $116/oz and $96/oz on the Q2 -2025 and H1 -2025 total cash costs and

AISC, respectively.

FY-2025 OUTLOOK

• The Group remains on track to achieve its FY -2025 production guidance of 1,110 – 1,260koz at its AISC cost guidance of

$1,150 – 1,350/oz. FY-2025 production is expected to be slightly weighted towards H1 -2025, due to lower grades expected at

the Houndé and Ity mines in H2 -2025, in line with their mine sequences. During H1 -2025, AISC has been impacted by higher

costs at Mana related to increased power costs driven by higher consumption and increased use of higher-cost self-generated

power, and higher sliding scale royalty costs due to higher realised gold prices (+$96/oz impact on AISC in H1-2025).

• Group AISC guidance of $1,150 – 1,350/oz is based on a realised average gold price of $2,000/oz, compared to the H1 -2025

realised gold price of $3,107/oz, resulting in a $96/oz impact on the H1 -2025 AISC from higher royalty costs. Prior to the

impact of the higher realised gold prices on royalty costs, H1 -2025 AISC was approximately $1,185/oz, and near the low -end

of the FY-2025 guidance range. Inclusive of the impact of higher realised gold prices on royalty costs, the H1 -2025 AISC was

$1,281/oz, and near the mid -point of the FY -2025 guidance range. The AISC sensitivity to royalty cost due to gold price

changes is between $6 - 10/oz for every $100/oz increase in gold price.

• Group sustaining capital expenditure outlook for FY -2025 has decreased from $215.0 million to $195.0 million, with $113.6

million incurred in H1 -2025, and $58.5 million incurred in Q2 -2025. The decrease in the FY -2025 sustaining capital

expenditure outlook is due to lower sustaining waste stripping, which has been offset by an increase in non -sustaining waste

pre-stripping, due to the acceleration of Pushback 2 at the Main pit at Lafigué. Sustaining capital for FY -2025 includes

underground development at Mana, mining fleet rebuilds and replacements at Houndé and Sabodala -Massawa and

processing plant and infrastructure upgrades at Ity.

• Group non -sustaining capital expenditure outlook for FY -2025 has increased from $215.0 million to $235.0 million for FY -

2025, with $102.9 million incurred in H1 -2025, and $65.3 million incurred in Q2 -2025. The increase in the FY -2025 non -

sustaining capital expenditure outlook is due to the acceleration of waste pre -stripping of Pushback 2 at the Main Pit at

Lafigué. Non-sustaining capital for FY -2025 includes waste stripping at Houndé, Ity, Lafigué and Sabodala -Massawa and TSF

embankment raises at Houndé, Ity and Mana.

• Growth capital expenditure outlook for FY-2025 has increased from $10.0 million to $30.0 million, with $15.9 million incurred

in H1-2025, primarily related to definitive feasibility study and drilling expenditure at Assafou. Growth capital expenditure at

Assafou has been accelerated due to additional advanced grade control and sterilisation drilling and the accelerated ramp -up

of the owners teams, prior to finalising the definitive feasibility study by early 2026.

• Exploration expenditure outlook for FY-2025 has been increased from $75.0 million to $85.0 million, of which $51.4 million

was incurred in H1-2025. The increased outlook is due to exploration successes at Ity and the accelerated programme at

Sabodala-Massawa to support the ongoing technical review, while the greenfield expenditure has been decreased slightly to

reflect the timing of greenfield and New Ventures exploration spend.

• Group tax payments outlook for FY-2025 remains unchanged at $350.0 million to $450.0 million, with $272.1 million incurred

in H1-2025 and $233.1 million incurred in Q2-2025. The remainder of the full-year tax payments are expected to amount to

25% of the full-year guidance in Q3-2025 and 5% of the full-year guidance in Q4-2025.

SHAREHOLDER RETURNS PROGRAMME

• For H1-2025, Endeavour announced a record dividend of $150.0 million or approximately $0.62 per share.

• During H1-2025, shareholder returns continued to be supplemented with share buybacks with $68.5 million, or 2.9 million

shares repurchased during the period, an increase of 245% compared to H1-2024. During Q2-2025, $28.1 million or 1.0

million shares were repurchased.

• As such, the total return for H1 -2025 was $218.5 million, which is equivalent to $338/oz produced for the period, with the

total shareholder returns for FY -2025 expected to increase over FY -2024 with additional supplemental dividends and share

buybacks in H2-2025.

• The H2-2025 dividend is expected to be declared in Q1 -2026 and paid in Q2 -2026. Supplemental returns are expected to be

paid in the form of dividends and opportunistic share buybacks, if the gold price exceeds $1,850/oz and if the Company has a

healthy financial position.

• As shown in the table below, Endeavour has now returned $1,398.5 million to shareholders in the form of dividends and

buybacks since its shareholder returns programme began in late 2020 (first payment in Q1 -2021), which represents $626.0

million or 81% above its minimum commitment and a return of $213/oz produced on a sustainable basis, through periods of

growth and cash harvest.

NOTES:

1) Operating cash flows decreased by $242.2 million from $494.2 million (or $2.03 per share) in Q1 -2025 to $252.0 million

(or $1.04 per share) in Q2-2025 due to higher income tax and withholding tax payments, a decrease in production, higher

operating costs, a higher realised loss on gold collars and higher royalties, partially offset by a decrease in the working

capital outflow.

Operating cash flows increased by $439.1 million from $307.1 million (or $1.25 per share) in H1-2024 to $746.2 million (or

$3.07 per share) in H1 -2025 due to higher production at higher realised gold prices, partially offset by higher operating

costs, higher royalties, a higher realised loss on gold collars and LBMA averaging, higher working capital outflows and

higher income tax payments.

Notable variances are summarised below:

• Working capital was an outflow of $44.1 million in Q2 -2025, an improvement of $53.9 million over the Q1 -2025

outflow of $98.0 million. The outflow in Q2 -2025 consisted of (i) an inventory outflow of $28.6 million due to a build -

up of stockpile inventory at the Ity and Sabodala -Massawa mines, partially offset by a decrease in gold -in-circuit

inventory at the Houndé and Ity mines, (ii) a receivables outflow of $18.6 million related to a build -up of VAT

receivables at the Houndé, Lafigué and Mana mines, and (iii) a trade and other payables outflow of $1.3 million

related to decreases in supplier payables and payroll -related liabilities, partially offset by (iv) a prepaid expenses and

other inflow of $4.4 million related to the timing of deposits and supplier prepayments.

Working capital was an outflow of $142.1 million in H1 -2025, an increase of $104.8 million over the H1 -2024 outflow

of $37.3 million, largely driven by an increase in outflows in trade and other receivables, an increase in outflows

related to inventories and an increase in outflows in trade and other payables, partially offset by an inflow of prepaid

expenses.

• Gold sales from continuing operations decreased from 353koz in Q1 -2025 to 304koz in Q2 -2025 due to lower

production at the Houndé, Mana and the Sabodala-Massawa mines, partially offset by increased production at the

Lafigué mine. The realised gold price from continuing operations for Q2 -2025 increased by $363/oz to $3,302/oz from

$2,939/oz in Q1 -2025. Inclusive of the Group’s Revenue Protection Programme ( -$151/oz Q2 -2025 impact), the

realised gold price for Q2-2025 increased by $367/oz to $3,150/oz from $2,783/oz in Q1-2025.

Gold sales from continuing operations increased from 463koz in H1 -2024 to 657koz in H1 -2025, following higher

production in H1 -2025 at the Houndé and Mana mines along with the addition of production from the Lafigué mine

and the Sabodala -Massawa BIOX expansion that achieved commercial production in Q3 -2024. The realised gold price

from continuing operations for H1 -2025 increased by $897/oz to $3,107/oz from $2,210/oz in H1 -2024. Inclusive of

the Group’s Revenue Protection Programme ( -$120/oz H1-2025 impact against a realised gold price of $3,107/oz in

H1-2025) and LBMA gold price averaging strategy ( -$33/oz H1-2025 impact against a realised gold price of $3,107/oz

in H1-2025), the realised gold price for H1-2025 increased by $786/oz to $2,953/oz from $2,167/oz in H1-2024.

• Total cash cost per ounce increased from $929/oz in Q1 -2025 to $1,220/oz in Q2 -2025 due to lower volumes of gold

sold, higher royalty costs related to a higher realised gold price and higher processing unit costs at the Houndé and Ity

mines due to seasonally lower grid power availability ahead of the wet season.

Total cash cost per ounce decreased from $1,079/oz in H1 -2024 to $1,064/oz in H1 -2025 due to higher volumes of

gold sold and the addition of the low -cost Lafigué and Sabodala -Massawa BIOX expansion, which both entered

commercial production in Q3-2024, partially offset by higher royalty costs related to the higher realised gold price.

• Taxes paid increased by $194.1 million, in line with the guidance provided, from $39.0 million in Q1 -2025 to $233.1

million in Q2 -2025 due to higher withholding tax payments related to annual cash upstreaming and an increase in

income taxes paid at the Houndé, Ity and Lafigué mines due to the timing of provisional income tax payments for the

FY-2024 tax year.

Taxes paid increased by $57.5 million from $214.6 million in H1 -2024 to $272.1 million in H1 -2025, in line with the

guidance provided, as income tax payments increased at the Houndé, Ity and Lafigué mines due to higher provisional

income tax payments for the FY -2024 tax year, while withholding tax payments also increased at the Houndé and

Mana mines due to increased cash upstreaming as a result of increased cash generation.

2) Cash flows used in investing activities increased by $62.9 million from $84.8 million in Q1 -2025 to $147.7 million in Q2 -

2025 due to an increase in non-sustaining capital spend during the quarter of $27.7 million, an increase in growth capital

expenditure related to the Assafou DFS of $4.5 million, an increase in sustaining capital spend during the quarter of $3.2

million, an increase in exploration expenditure of $2.6 million and a $3.5 million outflow of restricted cash.

Cash flows used in investing activities decreased by $126.4 million from $358.9 million in H1 -2024 to $232.5 million in H1-

2025 largely due to lower growth capital following the completion of the growth projects, which achieved commercial

production in Q3-2024, partially offset by higher sustaining and non-sustaining capital.

• Sustaining capital increased from $55.7 million in Q1 -2025 to $58.9 million in Q2 -2025, largely due to increased

sustaining capital expenditure at the Houndé mine related to heavy mining equipment additions and rebuilds, at the

Ity mine related to processing plant and infrastructure upgrades, partially offset by a decrease in sustaining capital

expenditure at the Mana and Sabodala-Massawa mines.

Sustaining capital increased from $51.3 million in H1 -2024 to $114.6 million in H1 -2025 due to the addition of the

Lafigué mine and the Sabodala -Massawa BIOX expansion, at the Mana mine related to underground development at

the Siou and Wona underground deposits and at the Sabodala -Massawa mine related to waste stripping and heavy

mining equipment additions, partially offset by a decrease in sustaining capital expenditure at the Houndé mine

related to reduced waste stripping activity at the Kari West pit.

• Non-sustaining capital increased from $37.6 million in Q1 -2025 to $65.3 million in Q2 -2025 largely due to waste

stripping at the Houndé and Sabodala -Massawa mines related to the Vindaloo Main pit phase 3 pushback and the
