ENDEAVOUR REPORTS FY-2024 PRELIMINARY RESULTS;

ANNOUNCES RECORD H2-2024 DIVIDEND

FY-2024 production of 1.1Moz at AISC of ~$1,220/oz ⚫ 2024 year-end leverage of <0.60x ⚫ FY-2024 shareholder returns of $277m

OPERATIONAL AND FINANCIAL HIGHLIGHTS (for continuing operations)

• Q4-2024 production of 363koz increased by 92koz or 34% over Q3-2024, while AISC decreased by approximately

~$147/oz or 11% to ~$1,140/oz.

• FY-2024 production of 1,103koz at an AISC of ~$ 1,220/oz, which was above the AISC guidance range due to lower

production and higher costs at Sabodala-Massawa, higher power costs and higher royalty costs due to high gold prices.

• Up to ~15% production growth expected in FY -2025 with production guidance of 1,110 - 1,260koz at a class-leading total

cash cost of $950-1,090/oz and AISC of $1,150-1,350/oz.

• Strong financial position at year-end with net debt of $732m, leverage less than 0.60x Net Debt to Adjusted EBITDA (LTM)

and $614m of available liquidity.

ROBUST SHAREHOLDER RETURNS

• H2-2024 record dividend of $140m or $0.57/sh announced, brings FY-2024 dividends to $240m or $0.98/sh;

supplemented with $37m of share buybacks for total returns of $277m, equivalent to $251/oz produced.

• Following the successful completion of its growth phase, Endeavour's shareholder returns programme aims to continue

to deliver attractive supplemental dividends with an increasing commitment to share buybacks.

ATTRACTIVE ORGANIC GROWTH

• Assafou PFS highlights a potential tier-1 asset with projected 329kozpa production at AISC of $892/oz over the first 10

years of its 15 year mine life; DFS is underway with expected completion in late 2025 to early 2026.

• Solar Power Plant construction at Sabodala-Massawa was completed on schedule with first power injected into the site

grid in Q4-2024; commissioning and ramp-up to nameplate power generation underway in Q1-2025.

• Significant exploration success achieved in FY-2024 with ~90% conversion of Assafou M&I resources into a 4.1Moz

maiden reserve; strong exploration focus maintained in FY-2025 with $75m guidance.

Ian Cockerill, Chief Executive Officer, commented: “2024 was a pivotal year for Endeavour. We successfully commissioned two

high-margin growth projects, delivered the preliminary feasibility study for the tier -1 Assafou project, and significantly increased

our free cash flow generation through the year, supporting record dividends for our shareholders.

Our robust operational performance resulted in 1.1 million ounces of production at a class -leading all -in sustaining cost of

~$1,220 per ounce. As expected, our operating performance was weighted toward the second half, driving improvements in free

cash flow generation through the year, accelerating balance sheet improvement, and we ended the year on track to achieve our

0.5x leverage target in the near term.

Given our low leverage and the recent cash flow inflection, we have declared a record dividend of $140 million for H2 -2024,

bringing total returns for FY-2024 to $277 million, or $251 for every ounce produced. Since we began our returns programme in

2021, we have now returned over $1.1 billion, 79% more than the minimum commitment for the period, reiterating our

commitment to paying supplemental shareholder returns.

We successfully delivered both the Sabodala -Massawa BIOX expansion and the Lafigué project on budget and on schedule in

under two years, declaring commercial production at both mines in August last year. After completing this phase of organic

growth, we outlined our next phase, with the completion of the pre -feasibility study for the Assafou project defining a potential

tier 1 cornerstone asset for Endeavour. Assafou is expected to support our organic production growth up to 1.5 million ounces by

the end of the decade, while improving the quality and diversification of our portfolio.

During the year, our exploration programme delivered significant resource to reserve conversion at Assafou and at Ity, as wel l as

resource additions at Ity and Sabodala -Massawa, in line with our long -term discovery targets. During 2025, we will focus on

adding resources at our cornerstone assets while we continue to delineate further opportunities for resource expansion at our

Assafou project.

I would like to thank our team for their continued hard work during 2024 that has created the foundation for further success in

2025. As we increase production by up to 15%, maintain stable costs and significantly reduce capex, driving higher free -cash flow

generation, our goal is to further increase returns to shareholders this year, through supplemental dividends and an increase d

commitment to share buybacks."

SHAREHOLDER RETURNS PROGRAMME

• Endeavour is pleased to continue to deliver attractive shareholder returns by announcing a record H2 -2024 dividend of

$140.0 million, or approximately $0.57 per share. As such, the FY-2024 dividend amounts to a annual record of $240.0 million

or approximately $0.98 per share, which includes $30.0 million of supplemental dividends, in excess of the $210.0 million

annual minimum commitment.

• Shareholder returns continue to be supplemented through the Company’s share buyback programme. A total of $37.0

million, or 1.8 million shares were repurchased during FY -2024, of which $8.0 million or 0.4 million shares were repurchased

in Q4-2024.

• For FY-2024, Endeavour returned $277.0 million to shareholders through dividends and share buybacks, 32% above the

$210.0 million minimum commitment for the year, and equivalent to $251/oz produced, reiterating Endeavour's strong

commitment to paying supplemental shareholder returns.

• Under Endeavour's new shareholder returns programme, that was announced in Q3 -2024 for the FY -2024 and FY -2025

period, the minimum dividend for FY -2025 is $225.0 million and this may be supplemented with both additional dividends

and increased opportunistic share buybacks.

• Dividends are expected to be paid semi-annually, provided that the prevailing gold price for the dividend period is at or above

$1,850/oz and the Company has a healthy financial position. 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.

qualify as an “eligible dividend” for Canadian income tax purposes. The tax consequences of the dividend will be dependent

on the particular circumstances of a shareholder.

• Endeavour is pleased to continue to offer a DRIP , to offer existing shareholders the opportunity, at their own election, to

increase their investment in Endeavour by receiving dividend payments in the form of ordinary shares in the Company.

• Participation in the DRIP is optional and available to shareholders, subject to local law, who hold shares on the London Stoc k

Exchange or on the Toronto Stock Exchange. Participants may opt to reinvest all, or any portion of their dividends in the DRIP .

Custodians are reminded that as part of the terms and conditions of the DRIP , if you make a partial election on the DRIP , the

remaining shares on your holding will be paid out automatically in GBP and not in the default currency of your specific

holding(s). The enrolment form is available on Endeavour’s website. The last election date for participation in the H2 -2024

DRIP will be 25 March 2025.

• In accordance with the DRIP , Endeavour’s Registrar, Computershare, will use cash dividends payable to participating

shareholders to purchase ordinary shares in the open market on the Toronto Stock Exchange and the London Stock Exchange

at the prevailing market price.

Q4-2024 AND FY-2024 OPERATIONAL PERFORMANCE OVERVIEW

• Q4-2024 production increased by 92koz or 34% over Q3 -2024, to 363koz following increased production at all mines.

Production increased due to higher grades processed in line with the mine sequences, as previously guided, and higher

throughput following the end of the regional wet season, as well as the ramp up of the Sabodala-Massawa Expansion and the

Lafigué growth projects.

• Q4-2024 total cash costs ("TCC") decreased by $148/oz or 13% over Q3-2024 to approximately ~$980/oz due to lower costs at

Houndé, Mana and Lafigué largely due to higher gold sales as well as lower underground mining costs at Mana. This was

partially offset by slightly higher costs at Ity due to increased mining unit costs as haulage distances increased.

• Q4-2024 all-in sustaining costs ("AISC") decreased by $147/oz or 11% over Q3 -2024 to approximately $1,140/oz due to lower

costs at Houndé, Mana and Lafigué. This was partially offset by slightly higher costs at Ity due to increased sustaining capi tal

associated with plant upgrades, and at Sabodala -Massawa due to increased sustaining capital associated with fleet

replacements.

• FY-2024 production amounted to 1,103koz, in line with the previously disclosed outlook and slightly below the guided 1,130 -

1,270koz range, due to lower than guided production from Sabodala -Massawa. FY-2024 AISC amounted to approximately

$1,220/oz, in line with the previously disclosed outlook, and above the top end of the guided $955 - $1,035/oz range, due to

underperformance at Sabodala-Massawa (+$137/oz), higher royalty costs (+$51/oz) associated with the prevailing higher gold

price ($2,418/oz realised gold price vs $1,850/oz guided gold price) and low grid power availability during H1-2024 (+$27/oz),

which was partially offset by lower than expected costs at Lafigué due to lower stripping costs.

AISC guidance was based on a gold price of $1,850/oz compared to the realised gold price of $2,418/oz 3As previously disclosed, grid availability issues

increased self-generated power costs across Burkina Faso and Côte d'Ivoire assets during the FY-2024.

• FY-2024 production of 1,103koz increased by 31koz over the 1,072koz produced in FY-2023 from continuing operations due to

record production at Ity, increased production at Mana and the addition of Lafigué, partially offset by lower production at

Houndé following record production in FY -2023 and underperformance at Sabodala -Massawa. FY-2024 TCC increased by

$223/oz, from $837/oz in FY -2023 to approximately $1,060/oz in FY -2024 as TCC increased at Houndé, Ity, Mana and

Sabodala-Massawa due to higher royalty costs, the impact of low grid power availability in H1 -2024, as well as significantly

lower production at Sabodala-Massawa, partially offset by the H2 -2024 impact of the lower -cost Lafigué mine. FY-2024 AISC

increased by $251/oz, from $967/oz in FY-2023 to approximately $1,220/oz in FY-2024.

• The Group’s realised gold price, excluding the impact of realised gains and losses on gold hedges and inclusive of the

Sabodala-Massawa gold stream, was $2,620/oz and $2,418/oz for Q4-2024 and FY-2024 respectively. Including the impact of

the gold hedges, the Group's realised gold price from continuing operations was $2,590/oz and $2,349/oz for Q4 -2024 and

FY-2024 respectively.

and Wahgnion mines were divested on 30 June 2023.

2025 OUTLOOK

• As shown in Table 7 below, the production guidance for FY -2025 amounts to between 1,110 - 1,260koz, which marks an

increase of up to 157koz or ~15% over the FY -2024 production of 1,103koz. The increased production is due to the full year

contribution from the Lafigué mine, increased production at the Mana mine following the expansion of the Wona

underground deposit, and increased production at Sabodala -Massawa due to higher throughput, grades and recoveries

largely due to the full year contribution from the BIOX Expansion. Furthermore, the production guidance at Sabodala -

Massawa does not incorporate the impact of potential levers to increase near -term production that are currently being

assessed as part of a technical review, with further details in the Sabodala-Massawa section below. These increases in Group

production are expected to be partially offset by a decrease at Houndé due to lower grades in the mine sequence.

• As shown in Table 8 below total cash costs are expected to remain consistent with that achieved in FY -2024, within a class

leading $950-$1,090/oz guidance range. FY-2025 Total Cash Costs are expected to decrease at Mana and Sabodala-Massawa

due to higher production, to remain stable at Houndé and Lafigué, and to increase slightly at Ity due to lower production

relative to FY-2024 record production.

• As shown in Table 9 below the AISC is expected to remain consistent with that achieved in FY -2024 within a class -leading

$1,150-1,350/oz guidance range. FY -2025 AISC are expected to decrease at Mana largely due to underground mining

productivity initiatives, which is expected to be offset by an increase at Ity, due to slightly lower production and higher

sustaining capital, and an increase at Lafigué due to higher sustaining capital related to increased waste stripping

requirements. AISC are expected to remain stable at Houndé and Sabodala-Massawa.

• Group production and AISC are expected to be evenly distributed through FY -2025 and more details on individual mine

guidance have been provided in the below sections.

foreign exchange rate of 0.90. 3AISC for Lafigué and the Sabodala-Massawa BIOX expansion project are for the post-commercial production period.

• Total mine capital expenditure for FY-2025 is expected to be approximately $440.0 million, which marks a decrease of $160.0

million or 27% compared to FY -2024, as detailed in Table 10 below. Increases in sustaining capital are largely driven by the

addition of capitalised waste stripping at the expanded Sabodala -Massawa and new Lafigué mines, increased capitalised

underground development costs at Mana, and mining equipment replacements at Houndé. Non -sustaining capital

expenditure is expected to be largely flat year over year as increased waste development at Houndé and the newly

commissioned Lafigué is expected to be largely offset by decreased waste development at Mana and Ity, in addition to the

cessation of capital expenditure related to the Sabodala -Massawa Solar Plant. More details on individual mine capital

expenditures have been provided in the mine sections below.

• Growth capital spend for FY -2025 is expected to amount to approximately $10.0 million, which marks a decrease of $241.5

million compared to the FY -2024 expenditure of $251.5 million following the commissioning of the Lafigué mine and

Sabodala-Massawa BIOX expansion project. The FY -2025 expenditure is related to the Assafou project's definitive feasibility

study ("DFS") costs.

Q4-2024 vs Q3-2024 Insights

• Production increased from 74koz in Q3 -2024 to 109koz in Q4 -2024 due to higher -grade ore processed and increased tonnes

milled, partially offset by lower recovery rates.

– Total tonnes mined increased due to higher utilisation of the mining fleet following the end of the wet season. Tonnes of

ore mined increased as a higher volume of ore was mined at the high grade Kari Pump pit, which was partially offset by

the lower volumes of ore mined from the Vindaloo Main pit, in-line with the mine sequence.

– Tonnes milled increased due to higher mill utilisation as the mill feed contained less moisture following the end of the wet

season.

– Average processed grades increased due to a higher proportion of high grade ore sourced from the Kari Pump pit in the

mill feed.

– Recovery rates decreased due to the increased proportion of high grade, fresh ore from the Kari Pump pit in the mill feed,

with its lower associated recoveries.

• AISC decreased significantly from $1,379/oz in Q3 -2024 to ~$1,025/oz in Q4 -2024 due to the higher volume of gold sold,

partially offset by increased mining unit costs due to increased grade control drilling activities and increased haulage cost s

associated with the increase in ore tonnes mined from the Kari Pump pit.

FY-2024 Performance

• FY-2024 production totalled 288koz, near the top end of the guided 260 -290koz range, with strong H2 -2024 weighted

performance driven by high grade ore sourced from the Kari Pump pit. FY -2024 AISC amounted to approximately ~$1,295/oz,

which was above the guided $1,000 -1,100/oz range due to higher than expected processing unit costs following an increased

reliance on self -generated power in H1 -2024, higher than expected sustaining capital due to additional purchases of heavy

mining equipment and spare parts and higher royalties following a higher realised gold price.

• Production decreased from 312koz in FY-2023 to 288koz in FY-2024 in line with the mine sequence due to lower tonnes milled

and lower recovery rates, partially offset by an increase in average grades processed. FY -2024 AISC increased from $943/oz in

FY-2023 to approximately ~$1,295/oz in FY -2024 due to higher royalty costs compounded by the increase to the sliding scale

royalty rates in Burkina Faso effective from November 2023, higher sustaining waste stripping and HME additions, higher

mining costs due to increased fuel costs and higher processing costs due to the increased reliance on self-generated power.

2025 Outlook

• Houndé is expected to produce between 230-260koz in FY-2025 at AISC of $1,225-1,375/oz.

• Mining activities are expected to continue at the Vindaloo Main, Kari Pump, and Kari West pits, in addition to the re -

commencement of mining at the Vindaloo North pit. In H1 -2025, ore is expected to be primarily sourced from the Kari Pump,

Vindaloo Main and Vindaloo North pits with ongoing stripping activities focused on the Vindaloo North and Vindaloo Main

pits. In H2-2025, the majority of ore tonnes are expected to be sourced from the Kari West pit, supplemented with ore from

Vindaloo Main and Vindaloo North pits. Tonnes of ore milled is expected to decrease in FY -2025 as a lower proportion of soft

oxide ore from the Kari Pump pit is anticipated, while the Kari West pit is expected to advance into harder transitional and

fresh ore. Average grades are expected to decrease due to the lower proportion of higher -grade ore from the Kari Pump pit.

Recoveries are expected to improve due to a lower proportion of fresh Kari Pump ore in the mill feed, which has lower

associated recoveries. AISC is expected to remain stable in FY -2025, as higher mining and processing unit costs due to the

expected increase in fresh ore in the feed will be offset by lower sustaining capital expenditure.

• Sustaining capital expenditure is expected to decrease from $49.5 million in FY-2024 to approximately $40.0 million in FY-2025,

and primarily relates to mining fleet component rebuilds and replacements, processing plant equipment upgrades and waste

capitalisation in the Kari West area.
