Management will host a conference call and webcast today, 2 May 2024, 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. A copy 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: “Following my first quarter as Chief Executive Officer at Endeavour, I am

pleased that we have continued to make progress against our strategic objectives.

Our operational performance is tracking in line with our Group guidance, as production and costs are expected to progressivel y

improve throughout the year, with performance strongly weighted towards the second half, as our two organic growth projects

ramp up, and we expect significantly stronger performance from our Houndé mine.

We were delighted to have achieved first gold at the Sabodala-Massawa Expansion project on 18 April, and at our second growth

project, Lafigué, we have now started dry commissioning and are on track to deliver first gold in late Q2, a quarter ahead of

schedule. Lafigué will be the fifth growth project that we have completed over the last 10 years, all of which have been buil t on

budget and on schedule in two years or less. As we transition out of this phase of growth, we will renew our focus on optimis ing

our existing assets and continue developing our talented projects team, ahead of the next phase of growth.

Exploration at the Assafou deposit on the Tanda -Iguela property continues to demonstrate the project’s potential to become

another cornerstone asset for Endeavour. The aggressive drilling program has further extended the mineralised trend at the

Assafou deposit by over 400 metres, while drilling at potential satellite targets, in close proximity to Assafou, has also yi elded

promising results.

During the quarter we paid our H2 -2023 dividend of $100 million to shareholders and completed $13 million worth of share

buybacks. Since our first dividend payment in Q1 -2021, we have now returned $ 917 million to shareholders, equivalent to $ 211

for every ounce produced over the same period, demonstrating our commitment to paying supplemental returns. We have now

finished our first shareholder returns programme, and expect to outline the next phase of the programme early in H2.

Despite investing over $235 million in organic growth, exploration and shareholder returns during the quarter, our leverage

remains healthy at 0.80x net debt to adjusted EBITDA, and we are well positioned to quickly de -lever our balance sheet and

increase our commitment to shareholder returns, to reflect our transition from a phase of growth to one focused on cash flow

generation.

We look forward to advancing our strategy this year to further strengthen our business and benefit all our stakeholders.”

OPERATING SUMMARY

• Strong safety performance for the Group, with a Lost Time Injury Frequency Rate (“LTIFR”) from continuing operations of 0.11

for the trailing twelve months ending 31 March 2024.

• As previously disclosed, on 28 February 2024, we were saddened to report that a contractor colleague passed away on 27

February 2024, as a result of injuries sustained in an incident that occurred during maintenance activities at the Mana mine

in Burkina Faso. The health, safety and welfare of our colleagues remain our top priority and we are focussed on

improvements to contractor management, front-line supervision and reviewing operational procedures.

• The Group remains on track to achieve its FY -2024 production guidance of 1,130 – 1,270koz at an AISC within the $955 –

1,035/oz range, with performance strongly weighted towards H2-2024, as previously guided.

• Q1-2024 production from continuing operations amounted to 219koz, a decrease of 61koz over Q4 -2023, due to lower

production at Houndé and Sabodala -Massawa, which was partially offset by higher production at Ity and Mana. Production

decreased at Houndé as lower grade ore from the Kari West pit was mined and processed while waste stripping focused on

the higher-grade Kari Pump and Vindaloo Main pits in order to access higher grade ore in H2 -2024 in line with the mine

sequence. In addition, mining and processing activities were temporarily stopped for 11 -days due to the previously disclosed

sub-contractor led strike. At Sabodala -Massawa, lower tonnage of high grade ore was sourced from the Sabodala pit as the

pit approaches the end of its economic mine life. Production increased at Ity, in -line with the mine sequence due to higher

grade ore from the Ity pit in the mill feed, and at Mana, as underground mining ramped up to deliver increased underground

ore tonnage to the mill.

• Q1-2024 AISC from continuing operations amounted to $1,186/oz, an increase of $239/oz over Q4 -2023 due largely to lower

volumes of gold sold at Houndé and Sabodala-Massawa, in addition to higher processing costs at Houndé, Sabodala-Massawa

and Ity as a result of increased power costs, a harder ore blend and commissioning costs associated with the Recyn

optimisation initiative, respectively. The increases were partially offset by a decrease at Mana due to higher gold volumes

sold and decreased unit rates as underground development activities continued to ramp-up.

• Sustaining capital expenditure outlook for FY-2024 remains unchanged at $125.0 million, of which $29.7 million was incurred

in Q1 -2024 primarily related to ongoing waste development activities at Houndé, Sabodala -Massawa and Ity, as well as

underground development at Mana.

• Non-sustaining capital expenditure outlook for FY -2024 remains unchanged at $190.0 million, of which $41.3 million was

incurred in Q1 -2024 primarily related to Solar Power plant construction at Sabodala -Massawa, TSF construction and

4

embankment raises at Houndé, Ity and Mana, pre -stripping activities at the Walter and Bakatouo pits and the ongoing

Mineral Sizer optimisation initiative at Ity.

• Growth capital expenditure outlook for FY-2024 remains unchanged at $245.0 million, of which $98.7 million was incurred in

Q1-2024 primarily related to construction activities at the BIOX® expansion project in Senegal ( $39.8 million incurred in Q1-

2024), the Lafigué development project in Cote d’Ivoire ( $56.7 million incurred in Q1-2024) and additional spend related to

the Kalana project.

SHAREHOLDER RETURNS PROGRAMME

• Endeavour implemented a dividend policy in 2021, with the goal of supplementing its minimum dividend commitment with

additional dividends and share buybacks provided that the prevailing gold price remained above $1,500/oz and its leverage

remained below 0.5x Net Debt / adj EBITDA.

• Endeavour's goal is to increase its shareholder returns programme once its organic growth projects are completed, while

strengthening its balance sheet, thereby ensuring that its efforts to unlock growth immediately benefit all stakeholders. The

updated dividend framework for the next phase of Endeavour’s shareholder returns policy is expected to be announced in

early H2-2024.

• As previously announced, the FY -2023 dividend amounted to $200.0 million, which represents $25.0 million or 14% more

than the minimum dividend commitment of $175.0 million for the year, reiterating Endeavour's commitment to paying

supplemental shareholder returns. The H2 -2023 dividend of $100.0 million, or $0.41 per share, was paid on 25 March 2024

to shareholders of record on 23 February 2024.

• During Q1-2024, shareholder returns continued to be supplemented with share buybacks with $12.6 million or 0.7 million

shares repurchased during the period. Since the commencement of the buyback program, $316.1 million or 14.4 million

shares have been repurchased as at 31 March 2024.

• Since the first shareholder returns payment in Q1 -2021, the Company has now returned $916.5 million to shareholders

including $600.4 million of dividends and $316.1 million of share buybacks; equivalent to returning $211 per ounce of gold

produced from all operations over the same period.

NOTES:

1) Operating cash flows decreased by $111.6 million from $166.7 million (or $0.68 per share) in Q4 -2023 to $55.1 million (or

$0.22 per share) in Q1 -2024 due largely to lower volumes of gold sold and higher cash costs, partially offset by higher

realised gold prices and lower taxes paid.

Operating cash flows decreased by $150.5 million from $205.6 million (or $0.83 per share) in Q1 -2023 to $55.1 million (or

$0.22 per share) in Q1 -2024 due to lower production, increased operating costs, an increased working capital outflow,

and higher tax payments, which was partially offset by the higher realised gold price.

Notable variances are summarised below:

• Working capital was an outflow of $82.3 million in Q1 -2024, an increase of $2.8 million over the Q4 -2023 outflow of

$79.5 million. The outflow in Q1 -2024 was largely driven by a trade and other payables outflow of $34.7 million

related to supplier payments at Houndé and Ity, the timing of employee payables related to annual bonuses and

settlement of an indirect tax claim at Sabodala -Massawa. An outflow of inventories of $30.6 million mainly related to

a build-up of stockpiles for the BIOX® Expansion at Sabodala -Massawa and the Lafigué project ahead of commercial

operations. And an outflow in trade and other receivables of $17.8 million related to a build -up of VAT receipts across

Sabodala-Massawa, Houndé and Mana and the timing of payments for the last gold shipment conducted during the

quarter. These outflows were partially offset by a small prepaid expenses and other inflow of $0.8 million.

Working capital was an outflow of $82.3 million in Q1 -2024, an increase of $54.1 million over the Q1 -2023 outflow of

$28.2 million, largely driven by an increase in inventory outflows related to a build -up of stockpiles ahead of the two

project start-ups and an increase in trade and other receivables related to a build -up of VAT receipts across Sabodala-

Massawa, Houndé and Mana related to the timing of reimbursements.

• Gold sales from continuing operations decreased from 285koz in Q4 -2023 to 225koz in Q1 -2024 due to decreased

production as FY-2024 production is weighted towards the second half of the year at Houndé where stripping activity

was prioritised in Q1 -2024, and at Sabodala -Massawa where lower tonnage of high grade ore was sourced from the

Sabodala pit in Q1 -2024. The realised gold price from continuing operations for Q1 -2024 was $2,091 per ounce

compared to $2,007 per ounce for Q4-2023. Inclusive of the Group’s Revenue Protection Programme, the realised gold

price for Q1-2024 was $2,041 per ounce compared to $1,945 per ounce for Q4-2023.

Gold sales from continuing operations decreased from 252koz in Q1 -2023 to 225koz in Q1 -2024, following lower

Group production in Q1 -2024. The realised gold price from continuing operations for Q1 -2024 was $2,091 per ounce

compared to $1,902 per ounce for Q1-2023. Inclusive of the Group’s Revenue Protection Programme, the realised gold

price for Q1-2024 was $2,041 per ounce compared to $1,879 per ounce for Q1-2023.

• Total cash cost per ounce increased from $837 per ounce in Q4-2023 to $1,007 per ounce in Q1-2024, primarily due to

decreased gold sales and higher strip ratios at Houndé and Sabodala -Massawa as stripping activity was prioritised in

Q1-2024, and increased processing costs across the Group due to a combination of harder ore blends and higher

power costs in Burkina Faso due to the increased reliance on self generated power during the dry season, as

contributions from hydropower to the national grid were lower during the quarter.

Total cash cost per ounce increased from $792 per ounce in Q1 -2023 to $1,007 per ounce in Q1 -2024 due to

decreased gold sales, increased waste development and higher mining unit costs at Houndé and Sabodala -Massawa

and higher processing unit costs across the Group.

• As shown in the table below, i ncome taxes paid decreased by $19.6 million from $70.9 million in Q4 -2023 to $51.3

million in Q1-2024 due to significantly less withholding taxes associated with the upstreaming of cash during Q1 -2024,

no taxes paid at Ity as the first provisional payment of the year is payable in Q2 -2024 and lower taxes paid at Houndé

and Mana largely due to the timing of payments, which was partially offset by an increase in taxes paid at Sabodala as

the first provisional income tax payment of the year was payable in Q1-2024.

Income taxes paid increased by $26.9 million from $24.4 million in Q1 -2023 to $51.3 million in Q1 -2024 due largely to

the increase in taxes paid at Sabodala-Massawa as provisional tax payments in the quarter were based on the FY -2023

tax base, which considers higher taxable earnings as FY-2022 benefited from a tax holiday on the Massawa licenses.

2) Cashflows used in investing activities decreased by $23.5 million from $211.0 million in Q4 -2023 to $187.5 million in Q1-

2024 due to a decrease in growth capital spend as the two growth projects advance towards completion, and a decrease

in non-sustaining capital due to reduced pre -stripping activities, partially offset by an increase in sustaining capital due to

increased stripping activities at Houndé and Sabodala-Massawa.

Cashflows used in investing activities decreased by $12.8 million from $200.3 million in Q1 -2023 to $187.5 million in Q1 -

2024 largely due to a decrease in non-sustaining capital spend across the group related to reduced pre-stripping activities,

reduced underground development at Mana and reduced spending on optimisation initiatives.

• Sustaining capital from continuing operations increased from $20.0 million in Q4 -2023 to $29.7 million in Q1 -2024,

largely due to increased sustaining capital expenditure at Houndé (increased waste stripping activities across the Kari

Pump and Vindaloo Main pits) and Sabodala -Massawa (increased waste stripping), partially offset by decreased

sustaining capital expenditure at Mana (lower proportion of underground waste development being capitalised during

the quarter) while sustaining capital spends at Ity were relatively stable.

Sustaining capital from continuing operations increased slightly from $27.7 million in Q4 -2023 to $29.7 million in Q1 -

2024 as higher sustaining capital expenditure at Houndé was largely offset by lower sustaining capital expenditure at

Sabodala-Massawa related to reduced waste stripping activities.

• Non-sustaining capital from continuing operations decreased from $52.5 million in Q4 -2023 to $41.3 million in Q1 -

2024, largely due to a decrease in non -sustaining capital at Sabodala -Massawa (reduced infrastructure and pre -

stripping of the Niakafiri East and Sofia North Extension pits), at Ity (reduced cutback activities at the Walter pit) and

at Houndé (reduced pre-stripping activities in the Kari Pump pit) partially offset by increased non -sustaining capital at

Mana (increased development of the underground).

Non-sustaining capital from continuing operations decreased from $83.9 million in Q1 -2023 to $41.3 million in Q1 -

2024 due to decreased non -sustaining capital expenditure at Ity (reduced Recyn costs, TSF costs, and Le Plaque pre -

stripping costs), at Sabodala -Massawa (reduced pre -stripping), at Houndé (reduced pre -stripping activities at Kari

Pump), and at Mana (reduced underground waste development as development advanced into ore).

• Growth capital decreased from $155.0 million in Q4 -2023 to $98.7 million in Q1 -2024, as cash outflows associated

with the BIOX® and Lafigué growth projects decreased as construction activities approached completion. Growth

capital expenditure during the quarter also included $2.2 million for work related to the Kalana project.

Growth capital increased from $72.2 million in Q1 -2023 to $98.7 million in Q1 -2024 due to the timing of construction

activities at the Sabodala-Massawa expansion, which was launched in Q2 -2022, and the Lafigué development project,

which was launched in Q4-2022.

3) Cash flows generated from financing activities increased by $166.7 million from an outflow of $79.0 million in Q4 -2023 to

an inflow of $87.7 million in Q1 -2024 largely due to the drawdown on debt facilities, partially offset by the timing of

dividend payments to shareholders. Financing cash inflows in Q1 -2024 included $219.3 million in proceeds from long -

term debt including $180.0 million drawn on the Company’s Revolving credit Facility (total amount of $645.0 million

drawn as at Q1-2024) and $39.3 million drawn on the Lafigué Term loan (total amount of $146.5 million drawn as at Q1 -

2024) partially offset by financing cash outflows which included the payment of the H2 -2023 dividend to shareholders of

$100.0 million, acquisition of the Company’s own shares through its share buyback programme of $16.8 million, payment

of finance and lease obligations of $5.7 million, payment of dividends to minorities of $4.9 million, payments of financing

and other fees of $4.0 million, and payments for the settlement of tracker shares of $0.2 million.

Cash flows generated from financing activities increased by $243.4 million from an outflow of $155.7 million in Q1 -2023

to an inflow of $87.7 million in Q1 -2024 largely due to the draw down on the company’s long -term debt facilities during

the current period.

4) At quarter end, Endeavour’s liquidity remained strong at $481.5 million, consisting of $461.0 million of cash and cash

equivalents and $20.5 million available through the Lafigué Term Loan.

5) Endeavour’s net debt position has increased by $275.5 million, from $555.0 million at the end of Q4 -2023 to $830.5

million at the end of Q1 -2024 due to the Company’s ongoing investments in its organic growth projects, exploration and

the timing of dividend payments. The Company’s net debt / Adjusted EBITDA (LTM) leverage ratio remains healthy, albeit

above its long -term target of 0.50x, at 0.80x at the end of Q1 -2024. Following the completion of the current growth

phase, the Company’s leverage is expected to return to levels below the long-term target.

NOTES:

6) Revenue decreased by $106.6 million from $579.3 million in Q4 -2023 to $472.7 million in Q1 -2024 due to a decrease in

gold sales from continuing operations as production decreased at Houndé and Sabodala -Massawa, which was partially

offset by an $84 per ounce increase in the realised gold price from $2,007 per ounce in Q4 -2023 to $2,091 per ounce in

Q1-2024, exclusive of the Company’s Revenue Protection Programme.

Revenue decreased by $8.5 million from $481.2 million in Q1-2023 to $472.7 million in Q1-2024 due to a decrease in gold

sales from continuing operations, partly offset by a higher realised gold price for Q1 -2024 of $2,091 per ounce compared

to $1,902 per ounce for Q1-2023, exclusive of the Company’s Revenue Protection Programme.

7) Operating expenses decreased by $8.8 million from $208.7 million in Q4-2023 to $199.9 million in Q1-2024 largely due to

lower production volumes at Houndé and Sabodala -Massawa, which was partially offset by higher processing costs at Ity

(increased throughput) and Mana (increased throughput and self -generated power costs). Depreciation and depletion

decreased by $23.9 million from $132.6 million in Q4 -2023 to $108.7 million in Q1 -2024 mainly due to lower production

at Houndé and Sabodala-Massawa.

Operating expenses increased by $28.5 million from $171.4 million in Q1-2023 to $199.9 million in Q1-2024 largely due to

increased strip ratios at Sabodala -Massawa and Houndé, increased underground mining costs at Mana driven by higher

volumes and increased processing costs at Houndé and Mana due to increased use of self generated power. Depreciation

and depletion increased by $6.8 million from $101.9 million in Q1 -2023 to $108.7 million in Q1 -2024 due to higher

depreciable costs at Mana which now has a higher capitalised cost base and at Sabodala -Massawa which has a lower

depletable reserves base in Q1-2024 following the FY-2023 reserves and resource update.

8) Royalties decreased by $6.4 million from $40.3 million in Q4 -2023 to $33.9 million in Q1 -2024 due to lower production

volumes compared to the prior quarter, partially offset by a higher realised gold price.

Royalties increased by $4.2 million from $29.7 million in Q1 -2023 to $33.9 million in Q1 -2024 due to a full quarter under

the the royalty rate structure in Burkina Faso, partially offset by lower production volumes.

9) Corporate costs decreased from $11.1 million in Q4 -2023 to $10.5 million in Q1 -2024 due to lower professional service

costs.

8

Corporate costs decreased from $13.5 million in Q1 -2023 to $10.5 million in Q1 -2024 due to lower professional service

costs.

10) Other expenses decreased from $45.1 million in Q4 -20233 to $16.6 million in Q1 -2024. For Q1 -2024, other expenses

included $8.1 million in tax claims related to Sabodala -Massawa and a temporary voluntary tax payment of 2% of profits

before tax and interest from the Houndé and Mana mines, $6.3 million in costs related to the investigation into the

former Chief Executive Officer’s misconduct, $5.9 million in legal and other costs primarily related to the ongoing

arbitration process around the non -core asset disposals, $0.7 million in restructuring costs, $0.5 million in community

contributions and $0.2 million in disturbance cost, partially offset by a $4.5 million gain on the disposal of the Afema asset

and a $0.6 million revaluation of receivables.

11) Exploration costs of $5.4 million in Q1-2024 were largely consistent with the prior quarter .

Exploration costs decreased from $12.5 million in Q1 -2023 to $5.4 million in Q1 -2024 largely due to a decrease in

expensed exploration at the Tanda-Iguela property, following the commencement of the pre-feasiblity study.

12) The loss on financial instruments decreased from a loss of $84.3 million in Q4 -2023 to a loss of $46.2 million in Q1 -2024

largely due to a decrease in unrealised losses on gold collars and forwards. The loss on financial instruments during the

quarter included unrealised losses on gold collars and forward sales of $22.8 million, realised losses on gold collars and

forward contracts of $11.4 million including $5.9 million related to the Group’s Revenue Protection Programme and $5.5

million related to the Group’s London Bullion Market Association (“LBMA”) gold price averaging strategy, unrealised

foreign exchange losses of $11.2 million, unrealised losses on Net Smelter Royalties (“NSRs”) and deferred compensation

related to asset sales of $1.1 million, and unrealised losses on foreign currency contracts of $0.8 million, which was

partially offset by an unrealised gain on the early redemption feature of senior notes of $0.6 million, an unrealised gain

on marketable securities of $0.3 million, and realised gains on foreign currency contracts of $0.2 million.

The loss on financial instruments decreased from a loss of $72.0 million in Q1 -2023 to a loss of $46.2 million in Q1 -2024,

due largely to mark -to-market adjustments in relation to gold hedges and exchange rate movements between the Euro

and the US dollar.

As previously disclosed, in order to increase cash flow visibility during its construction and de -leveraging phases,

Endeavour entered into a Revenue Protection Programme, using a combination of zero premium gold collars and forward

sales contracts, to cover a portion of its 2023, 2024 and 2025 production.

• During Q1 -2024, 35koz were settled into forward sales contracts for an average gold price of $2,024/oz. For the

remainder of FY-2024, approximately 339koz (approximately 113koz per quarter) are expected to be delivered into a

collar with an average call price of $2,400/oz and an average put price of $1,807/oz. In addition, approximately 35koz

are scheduled to be settled during Q2-2024 in forward sales contracts at an average gold price of $2,041/oz.

• For FY-2025, approximately 200koz are expected to be delivered into a collar with an average call price of $2,400/oz

and an average put price of $1,992/oz.

As previously disclosed, Endeavour entered into a Growth Capital Protection Programme designed to enhance cost

certainty for a portion of its growth capital expenditure at the BIOX® Expansion and Lafigué growth projects. The Group

had entered into various foreign exchange forward contracts across both the Euro and the Australian Dollar over 2023 and

2024.

• During Q1 -2024, €7.5 million was delivered into forward contracts at a blended rate of 1.04 EUR:USD and AU$3.3

million was delivered into forward contracts at a blended rate of 0.69 AUD:USD.

• The total outstanding notional forward contracted quantum is approximately €5.5 million at a blended rate of 1.04

EUR:USD over 2024 and approximately AU$2.4 million at a blended rate of 0.69 AUD:USD.

Subsequent to the end of Q1 -2024, on 26 April 2024 the Company entered into two separate gold prepayment

agreements for a total consideration of $150.0 million in exchange for the delivery of approximately 76koz in Q4 -2024.

The gold prepayments secure $150.0 million of financing for a low cost of capital of approximately 5.3%, and support the

Company’s offshore cash position during its peak investment phase. The prepayments are structured as follows:

• A $100.0 million agreement with the Bank of Montreal based on a floating arrangement for the delivery of

approximately 54koz in reference to prevailing spot prices for the settlement of $105.1 million (inclusive of $5.1

million in financing costs) in Q4-2024, with the value of the 54koz above the contracted $105.1 million reimbursement

at the time of delivery returned to Endeavour as cash.

• A $50.0 million agreement with ING Bank N.V. is based on a fixed arrangement for the delivery of ounces of

approximately 22koz for the settlement of $50.0 million in Q4 -2024. To mitigate the Group’s exposure to gold price

associated with the delivery of ounces under the fixed arrangement prepayment agreement, Endeavour has entered

into forward purchase contracts for 22koz at an average gold price of $2,408/oz due in Q4 -2024 to lock in a finance

cost of approximately $3.0 million.

13) Current income tax expense decreased by $34.3 million from $74.8 million in Q4 -2023 to $40.5 million in Q1 -2024 largely

due to a decrease in recognised withholding tax expenses, which decreased by $25.6 million from $30.1 million in Q4 -

2023 to $4.5 million in Q1-2024 due to the timing of local board approvals for cash upstreaming in addition to a decrease

in taxes due to lower earnings from mine operations.

Current income tax expense decreased by $7.7 million from $48.2 million in Q1 -2023 to $40.5 million in Q1 -2024 largely

due to lower taxable earnings in Q1-2024 compared to Q1-2023.
