instructions on how to participate, please refer to the conference call and webcast section at the end of the news release.

Sebastien de Montessus, President and CEO, commented: “We are very pleas ed with our solid operating and financial

performance over the first six months of the year, which has resulted in robust operating cash flow generation of more than $550

million. We are very proud to be on track to achieving both production and AISC guidance for the tenth consecutive year, despite

the macro environment, which is a reflection of the resilience of our business and the strong dedication of our team.

This strong performance allowed us to continue to execute our capital allocation strategy, which is focused on strengthening our

balance sheet, maximising shareholder returns and investing in our growt h. As such, during the period, we continued to

strengthen our balance sheet, increasing our net cash position by $141 million to reach $217 million, while also ret urning $108

million, in the form of dividend and buybacks, to shareholders.

In line with our strong s hareholder returns commitment, we are pleased to declare a H1-2022 dividend of $100 million, which

represents a 43% increase over last year’s dividend and is reflective of our improved financial position and confidence in our

business outlook. Moreover, we are now targeting a minimum dividend of $200 million for the year, which is $50 million more

than the initial minimum commitment. We are also continuing to supplement our shareholder returns with share buybacks,

having completed $38 million over the last six months and $176 million since launching the programme in April 2021.

Our capital returns programme has returned an impressive $476 million to shareholders since early 2021, inclusive of the

H1-2022 dividend, which represents approximately 10% of our current market capitalisation.

Looking ahead, we are excited with our growth prospects, with the priority being the Sabodala-Massawa plant expansion which

is progressing on-schedule and on budget, with already over a third of the total capital committed. We have also continued to

refine the DFS for our Lafigué project which is expected to be published in late Q3-2022. While, on the exploration front, we have

continued to aggressively drill, which has resulted in a number of new discoveries, for which we expect to publish resource

updates later in the year.

Given our strong performance across the business, we have significant momentum going into the second half of the year and are

well positioned to continue to generate value for our stakeholders over the long term.”

OPERATING SUMMARY

• Continued strong safety record for the Group, with a Lost Time Injury Frequency Rate (“LTIFR”) of 0.13 for continuing

operations for the trailing twelve months ending 30 June 2022.

• The Group is well positioned to achieve its FY-2022 production and all-in sustaining costs (“AISC”) guidance for continuing

operations of 1,315-1,400koz at an AISC of $880-930 per ounce.

• H1-2022 production from continuing operations amounted to 702koz, an increase of 6koz over H1-2021 due to full period

consolidation of production from Sabodala-Massawa as well as improved performance at Houndé (due to improved mining

flexibility with the addition of the Kari mining areas), offsetting lower production from Boungou and Wahgnion. H1-2022 AISC

from continuing operations increased by $62 per ounce over H1-2021 with higher AISC at Boungou, Ity, and Wahgnion, offset

by lower AISC at Mana and Sabodala-Massawa.

• Q2-2022 production from continuing operations amounted to 345koz, a decrease of 12koz over Q1-2022, as a result of lower

production at Sabodala-Massawa and Boungou in line with the mining sequence. This was slightly offset by higher production

at Houndé and Ity due to high grade ore in the feed from the Kari Pump and Le Plaque pits respectively. Q2-2022 AISC from

continuing operations increased in line with guidance by $106 per ounce over Q1-2022 to $954 per ounce mainly due to

stripping activity and mine scheduling ahead of the rainy season while Endeavour’s cost base benefitted from favourable

exchange rate variations, long-term supply contracts, production and cost optimisation initiatives, and the benefit of

regulated in-country fuel pricing mechanisms. As expected, key drivers for the higher AISC were: scheduled increased

operating and sustaining capital costs associated with mining and processing increased proportions of fresh rock sourced

from deeper elevations in the Boungou, Sabodala-Massawa and Wahgnion pits (approx. impact of $61 per ounce), higher

2

fuel prices (approx. impact of $39 per ounce), lower volumes of gold ounces sold (approx. impact of $38 per ounce), and

increased explosive prices (approx. impact of $13 per ounce). These factors were partially offset by foreign exchange benefits

as the euro continued to decline against the dollar (approx. impact of $37 per ounce) and reduced royalties (approx. impact

of $8 per ounce) due to the lower realised gold price.

Management Report.

NOTES:

1) Operating cash flows decreased by $51.1 million from $304.3 million (or $1.23 per share) in Q1-2022 to $253.2 million (or

$1.02 per share) in Q2-2022 due to a decrease in the realised gold price, a decrease in gold sales and the expected higher

costs, which were partially offset by a lower working capital outflow.

Operating cash flows increased by $59.2 million from $498.3 million (or $2.17 per share) in H1-2021 to $557.5 million (or

$2.24 per share) in H1-2022 due to an increase in the realised gold price, which was offset by higher working capital

outflows and lower gold sales.

Notable variances are summarised below:

• Changes in w orking capital were negligible in Q2-2022, an increase of $70.9 million over Q1-2022, as an increase in

inventories was largely offset by reductions in prepaid expenses and other payables.

Working capital was an outflow of $69.5 million in H1-2022, an increase of $55.2 million over H1-2021 due to an

increase in trade receivables at Sabodala-Massawa as VAT receivable increased following the startup of mining at the

Massawa pit and due to increased receivables from gold sales, offset slightly by a decrease in receivables at Mana and

Boungou as a result of VAT received during H1-2022.

• Gold sales from continuing operations decreased from 359koz in Q1-2022 to 344koz in Q2-2022 due primarily to

decreases in production at Sabodala-Massawa and Boungou. The realised gold price from continuing operations for

Q2-2022 was $1,832 per ounce compared to $1,911 per ounce for Q1-2022. Total cash cost per ounce increased from

$723 per ounce in Q1-2022 to $ 824 per ounce in Q2-2022, primarily due to the expected higher fuel and explosive

costs.

Gold sales from continuing operations decreased from 736koz in H1-2021 to 703koz in H1-2022 primarily due to lower

sales at Boungou, Ity and Wahgnion, partially offset by higher sales at Sabodala-Massawa and Houndé. The realised

gold price from continuing operations for H1-2022 was $1,872 per ounce compared to $1,779 per ounce for H1-2021.

Total cash cost per ounce increased from $715 per ounce in H1-2021 to $773 per ounce in H1-2022.

• Income taxes paid increased by $35.5 million from $28.7 million in Q1-2022 to $64.2 million in Q2-2022, due to an

increase in taxes paid at Ity by $19.8 million from $0.2 million in Q1-2022 to $20.0 million in Q2-2022 and an increase

at Houndé by $9.0 million from $8.8 million in Q1-2022 to $17.8 million in Q2-2022 which was largely related to the

final tax payments for the last financial year and the timing of payments at Houndé and Ity.

5

Income taxes paid decreased by $35.4 million from $128.3 million in H1-2021 to $92.9 million in H1-2022 largely due

to lower associated production at Boungou, a non-recurring charge at Ity in H1-2021 related to a customs audit and

lower withholding taxes.

2) Cashflows used in investing activities increased by $50.8 million from $93.8 million in Q1-2022 to $144.6 million in

Q2-2022 due to the ramp up at the Sabodala-Massawa expansion and increased capital expenditure at Sabodala-

Massawa, Houndé, Ity, Mana and Wahgnion. Cashflows used in investing activities for the HY-2022 were stable at $238.4

million in H1-2022.

• Sustaining capital from continuing operations increased from $30.8 million in Q1-2022 to $38.0 million in Q2-2022

primarily due to increased capitalised waste stripping activity at Houndé, Ity and Wahgnion.

Sustaining capital from continuing operations was relatively consistent with the prior period at $68.8 in H1-2022.

• Non-sustaining capital from continuing operations increased from $41.9 million in Q1-2022 to $53.2 million in

Q2-2022, due to TSF raise activities at Mana, Ity and Wahgnion, underground development at Mana, and engineering

works at the recyanidation project at Ity, which were partially offset by decreased spending at Houndé and Boungou.

Non-sustaining capital from continuing operations decreased from $112.2 million in H1-2021 to $95.1 million in

H1-2022, driven largely by a decrease at Ity where H1-2021 included spending for the Le Plaque haul road

construction and at Mana where H1-2021 spending included increased waste development spending coupled with

spending on the TSF raise.

• Growth capital spend increased as expected from $7.9 million in Q1-2022 to $34.3 million in Q2-2022 and primarily

relates to earthworks and early construction activities at the Sabodala-Massawa Expansion project and the DFS for

the Lafigué project and infrastructure upgrades.

Growth capital was relatively stable at $42.2 million in H1-2022 compared to the prior period as the prior period

incurred payment for the purchase of an additional stake in the Lafigué project property as announced on 21

December 2020.

3) Cash flows used in financing decreased by $24.2 million from $50.1 million in Q1-2022 to $25.9 million in Q2-2022.

Financing activities for Q2-2022 primarily consisted of payments of financing and other fees of $14.0 million, payments

for the acquisition of the Company’s own shares of $6.7 million, and repayment of finance and lease obligations of $5.2

million.

Cash flows used in financing decreased by $51.0 million from $127.0 million in H1-2021 to $76.0 million in H1-2022

largely due to the net repayment of $120.0 million of long-term debt in H1-2021.

4) At period-end, Endeavour’s liquidity remained strong with $ 1,096.8 million of cash on hand and $450.0 million undrawn

under the Revolving Credit Facility.

5) Endeavour’s net cash position increased by $50.2 million during Q2-2022 to $216.8 million, which provides the financial

flexibility to continue to supplement shareholder returns while maintaining headroom to fund organic growth.

NOTES:

8) Revenue decreased by $56.6 million from $686.2 million in Q1-2022 to $629.6 million in Q2-2022 mainly due to lower

production and sales from Sabodala-Massawa and Boungou, in line with the mining sequence, in addition to a lower

realised gold price in Q2-2022 of $1,832 per ounce compared to $1,911 per ounce for Q1-2022.

Revenue for H1-2022 increased by $5.7 million compared to H1-2021 due to the higher realised gold price of $1,872 per

ounce in H1-2022, compared to $1,779 per ounce in H1-2021, which was offset slightly by lower gold sold in H1-2022.

9) Operating expenses increased by $33.7 million from $217.5 million in Q1-2022 to $251.2 million in Q2-2022 due to higher

AISC due to the expected increased costs associated with fuel and explosives, as well as increased levels of stripping

activity during the quarter, ahead of the wet season. Depreciation and depletion decreased by $12.2 million from $152.0

million in Q1-2022 to $139.8 million in Q2-2022 mainly due to lower levels of production at the Sabodala-Massawa and

Boungou mines.

Operating expenses for the H1-2022 decreased by $41.4 million compared to H1-2021, primarily due to a decrease in

inventory adjustments at Sabodala-Massawa and the expense related to the change in inventory associated with gold

sold in excess of gold produced in H1-2021 following the Teranga acquisition. Depreciation and depletion for the H1-2022

increased by $30.3 million due to slightly higher production compared to the same period last year.

10) Royalties decreased from $41.0 million in Q1-2022 to $38.1 million in Q2-2022 despite the higher realised gold price, due

to lower levels of gold sales in Q2-2022. Royalties decreased slightly from $81.1 million in H1-2021 to $79.1 million in

H1-2022 due to lower gold sales, despite the higher realised gold price.

11) Corporate costs decreased from $14.0 million in Q1-2022 to $6.8 million in Q2-2022 due to lower costs associated with

employee and professional services, partially due to the payment of annual employee bonuses in Q1-2022. Corporate

7

costs also decreased from $30.2 million in H1-2021 to $20.8 million in H1-2022 due to the cessation of costs associated

with corporate integration and the LSE listing.

12) The loss on financial instruments of $178.8 million in Q1-2022 reversed to a gain of $106.8 million in Q2-2022 due

predominantly to an unrealised gain on gold forward sales of $72.8 million, an unrealised gain on gold collars of $33.5

million, an unrealised gain on the revaluation of the conversion option on the convertible notes of $31.7 million and a

gain on the change in fair value of the call rights of $5.6 million, which was offset by a foreign exchange loss of $38.5

million.

The gain on financial instruments of $28.9 million in H1-2021 decreased to a loss of $72.0 million in H1-2022 due to a loss

on foreign exchange of $58.0 million, an unrealised loss on gold collars of $10.3 million, an unrealised loss on forward

sales of $6.4 million, a realised loss on forward sales $5.6 million, a loss on the fair value of the redemption of senior

notes $4.6 million and a loss on change in fair value of warrant liabilities of $3.3 million, which was slightly offset by an

unrealised gain on the revaluation of the conversion option of the convertible notes of $13.7 million.

As previously disclosed, Endeavour entered into a revenue protection programme for a portion of its production across

FY-2022 and FY-2023, to provide greater cash flow visibility during its investment phase. This was structured as an

upfront low premium collar with a put price of $1,750 per ounce and a call price of $2,100 per ounce for 75koz of

production per quarter, from Q1-2022 until Q4-2023. In addition, the Company entered into forward sales contracts for

FY-2022 and FY-2023, for which 65koz at an average gold price of $1,834 per ounce and 99koz at an average gold price of

$1,834 per ounce were financially delivered in Q1-2022 and Q2-2022 respectively. Forward contracts scheduled to be

settled in Q3-2022 amount to 95koz at an average gold price of $1,834 per ounce, while 90koz at an average gold price of

$1,842 per ounce are scheduled to be settled in Q4-2022. For FY-2023, forward sales contracts amount to 120koz, or

30koz ounces per quarter at an average gold price of $1,828 per ounce.

13) Current income tax expense decreased by $10.0 million from $74.7 million in Q1-2022 to $64.7 million in Q2-2022 largely

due to a decrease in taxes at Boungou due to lower levels of productio n. Current income taxes increased by $23.1 million

from $116.3 million in H1-2021 to $139.4 million in H1-2022 due to an increase in tax expense at Sabodala-Massawa as a

result of the start-up of mining at the Massawa pits as well as an increase in taxable profit at Ity due to earnings

generated at Floleu, which includes the Le Plaque pit, which was partially offset by a decrease in tax expense at Boungou

associated with lower levels of production.

14) Deferred income tax recovery increased by $19.4 million from an expense $11.2 million in Q1-2022 to a recovery of $8.2

million in Q2-2022 due to timing difference between the tax base and the accounting base of assets and liabilities at Ity,

Houndé and Mana . In H1-2022, a deferred income tax expense of $3.0 million compared to a deferred tax recovery of

$13.4 million in H1-2021. In H1-2021, the Group benefitted from deferred tax recoveries at Sabodala-Massawa associated

with the unwinding of the fair value adjustment to inventory. The absence of these recoveries in H1-2022 contributed to

the decreased deferred tax tax expense for H1-2022.

15) Net comprehensive earnings from continuing operations of $204.5 million was recorded for Q2-2022 compared to a net

comprehensive loss of $35.2 million in Q1-2022. The increased earnings are largely attributed to strong earnings from

mine operations coupled with a gain on financial instruments associated with unrealised gains associated with fair value

adjustments on the gold collars and forward contracts, as well as the conversion feature on the convertible notes. For

H1-2022, net comprehensive earnings of $169.3 million was recognised, a decrease on the earnings of $256.2 million

recognised in H1-2021 due to the loss on financial instruments of $72.0 million recorded in H1-2022.

16) For Q2-2022, adjustments mainly included a gain on financial instruments of $106.8 million largely related to the

unrealised gain on forward sales, non-cash, tax and other adjustments of $24.8 million that mainly relate to the impact of

the foreign exchange remeasurement of deferred tax balances and non-cash fair value adjustments to inventory

associated with the purchase price allocation of Teranga, other expenses of $10.6 million and acquisition and

restructuring costs of $1.3 million. For H1-2022, adjustments mainly included a loss on financial instruments of $72.0

million largely related to the unrealised loss on forward sales, non-cash, tax and other adjustments of $36.3 million that

mainly relate to the impact of the foreign exchange remeasurement of deferred tax balances and non-cash fair value

adjustments to inventory associated with the purchase price allocation of Teranga, other expenses of $12.6 million and

acquisition and restructuring costs of $1.5 million, which were slightly offset by net earnings from the discontinued

Karma mine of $14.8 million.

17) Adjusted net earnings attributable to shareholders for continuing operations decreased by $22.3 million to $111.3

million (or $0.45 per share) in Q2-2022 compared to $133.6 million (or $0.54 per share) in Q1-2022 due largely to lower

earnings from mining operations as a result of lower group production at higher AISC during the quarter. In H1-2022

adjusted net earnings attributable to shareholders for continuing operations decreased to $244.9 million (or $0.99 per

share) from $281.5 million (or $1.22 per share) in H1-2021 due to higher income tax expense due to higher taxes at Mana

and Sabodala-Massawa, which was partially offset by higher earnings from mine operations and lower acquisition and

restructuring costs during H1-2022.
