London, 22 January 2024 – Endeavour Mining plc (LSE:EDV, TSX:EDV, OTCQX:EDVMF) (“Endeavour” or the “Group” or the “Company”) is pleased to announce its unaudited preliminary financial and operating results for the fourth quarter and full year 2023, with highlights provided in Table 1 below.

¹All Q4-2023 and FY-2023 numbers are preliminary and reflect Endeavour’s expected results as at the date of this press release. ²Production and AISC highlights from continuing operations ³This is a non-GAAP measure.

Ian Cockerill, CEO of Endeavour, commented: “I am honoured to assume the role of CEO at a pivotal time for Endeavour as strong foundations are in place to unlock significant value as we deliver on our organic growth pipeline. I look forward to continuing to implement the strategy approved by the Board and lead the Company forward for the benefit of all our stakeholders.

2023 was another successful year for Endeavour during which we continued to focus on improving the quality of our portfolio through asset optimisation initiatives, the divestment of non-core Boungou and Wahgnion mines, construction of our two high-margin, long life growth projects, and continue to deliver significant exploration success.

On the operational front, we are pleased to have met production guidance for the eleventh consecutive year and to remain one of the lowest all-in sustaining cost producers within the sector, allowing us to generate robust cash flow to fund both our organic growth and shareholder returns programmes. Moreover, we achieved record production at both Ity and Houndé in 2023 where production exceeded 300koz. As we look forward to continuing to optimise and explore these two mines with the goal of sustaining such levels of production over the long-term, Endeavour’s other flagship asset, Sabodala-Massawa, is well positioned to produce up to 400koz in 2024.

Article content

Regarding our near-term growth plans, we are very pleased to report that both the Sabodala-Massawa expansion and the Lafigué development project are progressing well, with both projects on budget and on, or ahead of, schedule for first production in the second quarter of 2024. Our longer-term organic growth pipeline is equally attractive, following the delineation of a 4.5 million ounce Indicated resource at our Tanda-Iguela greenfield property in Côte d’Ivoire. This represents one of the most significant discoveries in West Africa over the past decade and we have launched a preliminary feasibility study that we expect to finalise by year end, as we continue to focus on increasing its size.

Throughout last year, we continued to execute on our commitment to deliver attractive shareholder returns, returning $200 million of dividends for the year and having repurchased $66 million worth of shares, which combined is equivalent to $226 for every ounce of gold produced from all operations. Importantly, since we began the shareholder returns programme in 2021, we have returned over $900 million to shareholders representing 77% more than the minimum commitment for the period. Looking ahead, our goal is to increase returns further once our two ongoing organic growth projects are complete.

I would like to thank our team for their continued hard work. I look forward with excitement to 2024 and beyond as we will benefit from the efforts undertaken over recent years to improve the quality of our portfolio and strengthen the resilience of our business.”

SHAREHOLDER RETURNS PROGRAMME

• In line with Endeavour’s capital allocation framework, the Company is pleased to continue to deliver attractive shareholder returns by declaring a H2-2023 dividend of $100.0 million, or approximately $0.41 per share. As such, the FY-2023 dividend amounts 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 strong commitment to paying supplemental shareholder returns.
• Endeavour’s H2-2023 dividend will be paid on 25 March 2024, with an ex-dividend date of 22 February 2024, to shareholders of record on 23 February 2024. Shareholders of shares traded on the Toronto Stock Exchange will receive dividends in Canadian Dollars (“CAD”), but can elect to receive United States Dollars (“USD”). Shareholders of shares traded on the London Stock Exchange will receive dividends in USD, but can elect to receive Pounds Sterling (“GBP”). Currency elections and elections under the Company’s dividend reinvestment plan (“DRIP”) must be made by shareholders prior to 17:00 GMT on 4 March 2024. Dividends will be paid in the default or elected currency on the Payment Date, at the prevailing USD:CAD and USD:GBP exchange rates on 6 March 2024. This dividend does not 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.
• Shareholder returns are being supplemented through the Company’s share buyback programme. A total of $65.7 million, or 3.0 million shares were repurchased during FY-2023, of which $25.7 million or 1.3 million shares were repurchased in Q4-2023.
• As shown in Table 2 below, Endeavour has returned $266.0 million to shareholders for FY-2023 through dividends and share buybacks, 52% above the $175.0 million minimum dividend commitment for the year, and equivalent to $226 per ounce produced from all operations. Since the shareholder returns programme began to be paid in 2021, Endeavour has returned $903.0 million to shareholders in the form of dividends and buybacks, inclusive of the H2-2023 dividend, which represents $393.0 million or 77% more than its minimum commitment over the period.

Table 2: Actual Shareholder Returns vs. Minimum Commitment

¹H2-2023 dividend declared on 22 January 2024, to be paid on or about 25 March 2024.

• As previously stated, 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 higher gold prices 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, along with the strengthening of its balance sheet, thereby ensuring that its efforts to unlock growth immediately benefit all its stakeholders. Endeavour’s next semi-annual dividend is expected to be announced in early August, along with its Q2 and H1-2024 financial results.

FY-2023 OPERATIONAL PERFORMANCE OVERVIEW         

• Q4-2023 production from continuing operations amounted to 280koz and was flat over Q3-2023 as the anticipated decrease at Houndé was offset by increases at Sabodala-Massawa (albeit by less than anticipated due to the lower grades encountered in the Sabodala pit as it enters its final phase of mining) and Mana, while Ity remained flat. The all-in sustaining costs (“AISC”) decreased by $31/oz or 3.2% over Q3-2023 to approximately $936/oz despite a $24/oz increase in royalty costs linked to the higher realised gold price and the impact of the change in the sliding scale royalty rates in Burkina Faso, which came into effect in November 2023. The AISC benefitted from reductions at Sabodala-Massawa and Mana, which was offset by the increase at Houndé (following record Q3-2023 performance) while Ity remained flat.
• As shown in Table 3 below, the FY-2023 production from continuing operations amounted to 1,072koz, achieving the guided 1,060-1,135koz range and marking the 11th consecutive year of achieving or beating production guidance. The AISC from continuing operations amounted to an industry-leading ~$964/oz for FY-2023. In line with the previously disclosed outlook, Endeavour achieved near the top-end of guided $895-950/oz AISC range, albeit 1.5% (representing $14/oz) above due to royalties being $18/oz higher than anticipated due to a higher realised gold price ($1,952/oz compared to guidance of $1,750/oz) and the aforementioned increase in the Burkina Faso royalty rate which came into effect in November 2023.

¹All Q4-2023 and FY-2023 numbers are preliminary and reflect Endeavour’s expected results as at the date of this press release. ² 2023 AISC guidance was based on a gold price of $1,750/oz compared to the realised gold price of $1,952/oz

• FY-2023 production from continuing operations amounted to 1,072koz, which represents a decrease of 89koz or 8% over the 1,161koz produced in FY-2022 due to lower production at Mana (due to the transition from an open-pit to an underground operation at the Wona deposit) and at Sabodala-Massawa (due to mining and processing of lower grade ore), while both Houndé and Ity achieved record annual production. FY-2023 AISC from continuing operations increased by $114/oz, from $850/oz in FY-2022 to approximately $964/oz in FY-2023, as AISC increased at Houndé, Mana, Sabodala-Massawa and at Corporate, in addition to a $15/oz increase in royalty costs (from $108/oz in FY-2022 to $123/oz in FY-2023), which was partially offset by decreased AISC at Ity.
• The Group’s realised gold price from continuing operations, excluding the impact of realised gains on gold hedges and inclusive of the Sabodala-Massawa gold stream, was $2,034/oz and $1,952/oz for Q4-2023 and FY-2023 respectively. Including the impact of the gold hedges, the Group’s realised gold price from continuing operations was $1,945/oz and $1,919/oz for Q4-2023 and FY-2023 respectively.

2024 OUTLOOK

• As shown in Tables 6 and 7 below, the production guidance for FY-2024 amounts to 1,130-1,270koz which marks an increase of up to nearly 200koz or 18.5% over the FY-2023 production from continuing operations of 1,072koz, which is largely due to the commissioning of the Sabodala-Massawa expansion and the Lafigué projects in Q2-2024. The AISC is expected to remain consistent with that achieved over recent quarters at an industry-low $955-1,035/oz.
• Group production is expected to be more heavily weighted towards H2-2024 while AISC is also expected to be lower in H2-2024 as the Group’s organic growth projects are expected to significantly increase the quality of Endeavour’s portfolio.
• More details on individual mine guidance have been provided in the below sections.

¹All Q4-2023 and FY-2023 numbers are preliminary and reflect Endeavour’s expected results as at the date of this press release.

Q4-2023 vs Q3-2023 Insights

• Production decreased due to lower processed grades and slightly lower throughput and recoveries.
  • 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 in the Vindaloo Main pit, following waste stripping activity that was completed in Q3-2023, which was partially offset by the lower volumes of ore mined from the Kari Pump and Kari West pits, which was in-line with mine sequencing.
  • Tonnes milled decreased slightly due to a higher proportion of harder transitional and fresh ore in the mill feed.
  • Processed grades decreased due to lower grade oxide ore sourced from the Kari Pump pit as well as a greater proportion of lower grade Kari West and Vindaloo Main ore.
  • Recovery rates decreased slightly due to a higher proportion of transitional and fresh ore, with lower associated recoveries in the mill feed.
• AISC increased mainly due to lower production and sales, driven by the lower average grade in the ore blend.

¹All Q4-2023 and FY-2023 numbers are preliminary and reflect Endeavour’s expected results as at the date of this press release.

Q4-2023 vs Q3-2023 Insights

• Production remained flat as higher tonnes milled and higher processed grades were offset by lower recoveries.
  • Total tonnes mined increased, as anticipated, due to increased mining rates following the wet season in the prior quarter and increased stripping activities at the Walter pit cutback. Similarly, tonnes of ore mined increased following the end of the wet season as ore mining focussed on the Ity, Walter, Bakatouo and Le Plaque pits, with supplemental contributions from the Verse Ouest pit and stockpiles.
  • Tonnes milled increased due to higher crusher availability following the wet season impact in the prior quarter.
  • Processed grades increased slightly due to higher volumes of higher grade ore sourced from the Ity and Bakatouo pits in the mill feed, which was partially offset by lower grade ore sourced from the Walter and Le Plaque pits during the quarter.
  • Recoveries decreased due to a higher proportion of fresh ore, with lower associated recoveries, in the mill feed.
• AISC remained flat as higher royalty rates associated with higher gold prices were offset by lower processing unit costs associated with increased processing volumes following the end of the wet season.

¹All Q4-2023 and FY-2023 numbers are preliminary and reflect Endeavour’s expected results as at the date of this press release.

Q4-2023 vs Q3-2023 Insights

• Production increased due to higher average grades processed and recovery rates, which were partially offset by lower mill throughput.
  • Total open pit tonnes mined decreased, in-line with the mine plan, as mining activities began to ramp-down at the Maoula open pit.
  • Total underground tonnes of ore mined increased as total ore tonnes from Wona increased by 36% with a 40% increase in stope tonnes mined. Total underground development at Wona Underground and Siou Underground increased compared to the prior quarter with 3,017 meters developed, a 16% increase compared to Q3-2023.
  • Tonnes milled decreased as tonnes of ore mined from the Maoula open pit decreased and the plant was limited by available ore from underground sources.
  • The average processed grade increased due to a higher proportion of higher grade ore from the Wona underground deposit in the mill feed following an increase in stope tonnes mined.
  • Recovery rates increased slightly due to changes in the ore blend.
• AISC decreased due to higher volumes of gold sold and lower underground mining unit costs associated with the continued ramp-up of underground mining volumes.

¹All Q4-2023 and FY-2023 numbers are preliminary and reflect Endeavour’s expected results as at the date of this press release..

Q4-2023 vs Q3-2023 Insights

• Production increased due to an increase in processed grade and throughput, which was partially offset by a slight decrease in recovery rates.
  • Total tonnes mined decreased due to a decrease in mining activities at the Bambaraya pits in-line with the mine plan, and lower waste stripping at the Sabodala pit following stripping activities earlier in the year. The decrease was partially offset by increased stripping activities at the Massawa Central Zone pits to access higher-grade refractory ore zones ahead of the expected startup of the BIOX® Expansion project in Q2-2024, and higher mining volumes from the Niakafiri East and Sofia North Extension pits. Tonnes of ore mined increased as stripping activities earlier in the year provided greater access to ore zones at the Sabodala pit.
  • Tonnes milled increased as the ore blend contained a higher proportion of softer oxide ore from the Niakafiri East pit and stockpiles.
  • Average grade processed increased due to higher grade ore sourced from the Sabodala, Massawa Central Zone and Sofia North Extension pits, displacing the comparatively lower grade ore from the Bambaraya pits.
  • Recovery rates decreased slightly due to an increased proportion of transitional ore from the Massawa Central Zone pits in the mill feed impacting recoveries.
• AISC decreased largely due to increased gold sales driven by higher average grades and throughput, in addition to lower sustaining capital incurred during the period.

Lafigué Mine, Côte d’Ivoire

Project Construction Update

• Construction of the Lafigué project in Côte d’Ivoire was launched in early Q4-2022, following the completion of a DFS which confirmed Lafigué’s potential to be a cornerstone asset for Endeavour. First gold production is expected ahead of schedule in Q2-2024, rather than Q3-2024.
• Growth capital expenditure for the project is approximately $448.0 million, with $278.6 million, or 62%, of the growth capex incurred to date, of which $241.7 million was incurred in FY-2023 and approximately $170.0 million is expected to be incurred in FY-2024 mainly related to construction activities across the process plant, site infrastructure and commissioning activities.
• Approximately $377.2 million or 84% of the total growth capital has now been committed, with pricing in line with expectations.
• The construction progress regarding critical path items is detailed below:
  • Construction activities are well advanced with the crushing area, ball mills, HPGR installation, CIL tanks the elution area all nearing completion.
  • Process plant engineering and drafting is now completed and delivery of all the project shipments is over 95% complete with all key items on site.
  • Site infrastructure including the gold room, dry screening building and conveyor truss have been pre-assembled ahead of concrete pouring, to reduce erection time, and will be erected in H1-2024. The site camp facility is nearly completed, with the completed buildings in use since December 2023.
  • The 225kV power substation is complete with the Dabakala Switchyard and overhead power lines successfully energised during December 2023. Electrical works on site are also progressing to plan with underground high-voltage cable installation advancing on schedule.
  • TSF earthworks is complete and HDPE lining of the TSF is well advanced.
  • Mining equipment mobilisation has advanced well with mining activities commencing during the quarter with approximately 2,906kt of material moved.

NON-CORE ASSET DIVESTMENT

• On 30 June 2023, Endeavour closed the divestment of its 90% interests in its non-core Boungou and Wahgnion mines in Burkina Faso to Lilium Mining (“Lilium”), a subsidiary of Lilium Capital which is an African and frontier markets focused strategic investment vehicle led by West African entrepreneurs.
• The total consideration for the divestment is expected to exceed $300.0 million and is comprised of:
  • $130.0 million in the form of a reimbursement of historical shareholder loans, of which a total of $33.0 million was received to date. The remaining $97.0 million is outstanding as Lilium was delayed in closing its debt refinancing due to delays in its lending syndicate completing their credit approval process. Lilium is expected to obtain credit approval, close the refinancing and make the payments imminently.
  • $25.0 million in deferred cash consideration payable in two instalments of $10.0 million, which became payable in January 2024, and $15.0 million, which will become payable in April 2024. Both payments are expected to be received in the coming months.
  • Deferred cash consideration comprised of 50% of the net free cashflow generated by the Boungou mine until $55.0 million has been paid. No payments have thus far been received for this deferred cash consideration as Lilium has not had any commercial production from Boungou since their acquisition given their election to place the mine on care and maintenance due to supply chain challenges and security.
  • An NSR on Wahgnion commencing at closing for 4.0% of gold sold, of which a total of approximately $2.6 million has been received as at December 31, 2023.
  • An NSR on Boungou commencing at closing for 4.0% of gold sold, of which a total of approximately $0.5 million has been received as at December 31, 2023.

FINANCIAL POSITION & LIQUIDITY

• As shown in Table 14 below, Endeavour ended FY-2023 with a net debt position of $555.3 million, which represents a $110.2 million increase compared to the prior quarter and $676.4 million increase over the previous year. The increase in the Company’s net debt position is due to the ongoing investment in the Sabodala-Massawa Expansion and the Lafigué Development project, with $447.1 million of growth capital spent during the year, in addition the Company paid $200.0 million in shareholder dividends and $65.7 million in share buybacks during the year. Furthermore, following the divestment of the non-core Boungou and Wahgnion mines to Lilium on 30 June 2023, the details of the outstanding upfront proceeds of $97.0m and the deferred payment of $10.0m that were expected to be received in Q4-2023, are included in the “Non-Core Asset Divestment” section above.

Actual reported fourth quarter and 2023 results are subject to management’s final review, as well as audit by the company’s independent accounting firm, and may vary significantly from those expectations because of a number of factors, including, without limitation, additional or revised information, and changes in accounting standards or policies, or in how those standards are applied. The fourth quarter and 2023 AISC include expected amounts for year-end accrual and working capital adjustments. Endeavour will provide additional discussion and analysis and other important information about its 2023 production and AISC levels when it reports actual results.

NON-GAAP MEASURES

Some of the indicators used by Endeavour in this press release represent non-IFRS financial measures, including “all-in sustaining cost”, “net cash / net debt”, “EBITDA”, “adjusted EBITDA”, “net cash / net debt to adjusted EBITDA ratio”, “cash flow from continuing operations”, “total cash cost per ounce”, “sustaining and non-sustaining capital”. These measures are presented as they can provide useful information to assist investors with their evaluation of the pro forma performance. Since the non-IFRS performance measures listed herein do not have any standardised definition prescribed by IFRS, they may not be comparable to similar measures presented by other companies. Accordingly, they are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Please refer to the non-GAAP measures section in this press release and in the Company’s most recently filed Management Report for a reconciliation of the non-IFRS financial measures used in this press release.
