Endeavour Reports Strong Q1-2026 Results

• Houndé is on track to achieve its FY-2026 production guidance of 220koz – 255koz, at an AISC within the guided $1,800/oz – $2,000/oz range, when adjusted for the impact of higher gold prices on royalty costs (+$327/oz impact for Q1-2026 due to the realised gold price of $4,835/oz, compared to the guidance gold price of $3,000/oz). Operating performance is weighted towards H2-2026 due to mining and processing of higher average grades from the Vindaloo Main pit following waste stripping in H1-2026.
• During the remainder of FY-2026, ore is expected to be sourced primarily from the Kari West pit with supplemental ore sourced from the Vindaloo Main pit. Throughput and average grades processed are expected to increase through the year as stripping activity in the Vindaloo Main pit advances, providing access to progressively softer oxide ore at higher grades.
• Sustaining capital expenditure outlook for FY-2026 remains unchanged at $50.0 million, of which $15.6 million has been incurred in Q1-2026. During FY-2026 sustaining capital expenditure is expected to primarily relate to mining equipment additions and rebuilds.
• Non-sustaining capital expenditure outlook for FY-2026 remains unchanged at $60.0 million, of which $28.4 million has been incurred in Q1-2026. During FY-2026 non-sustaining capital expenditure is expected to primarily relate to the Vindaloo Main pit phase 3 pushback, the construction of TSF 2, the construction of the TSF stage-10 embankment raise and the establishment of the Vindaloo South East pit.

• Production decreased from 74koz in Q4-2025 to 69koz in Q1-2026 due to lower average grades milled and lower mill throughput, partially offset by higher recovery rates.
  • Total tonnes mined and tonnes of ore mined increased due to increased fleet productivity, with an increased focus on ore sourced from the Le Plaque and Bakatouo pits to compensate for the lower mined grade at the Walter and the Bakatouo pits, in line with the mine sequence. Ore tonnes were sourced from the Bakatouo, Walter, Zia, Le Plaque, Verse Ouest and Ity pits.
  • Tonnes milled decreased due to lower mill availability as a result of the timing of planned maintenance work.
  • Average processed grades decreased slightly due to an increased proportion of lower grade ore from the Walter and Bakatouo pits in the mill feed, partially offset by higher grade ore sourced from the Ity pit and the Heap Dump.
  • Recovery rates increased due to improved ore blending following the implementation of improved stockpiling strategies.
• AISC decreased from $1,523/oz in Q4-2025 to $1,471/oz in Q1-2026 driven by lower sustaining capital and higher by-product revenue from silver sales. These benefits were partially offset by higher royalties (+$120/oz impact for Q1-2026 due to the higher realised gold price of $4,770/oz compared to the realised gold price of $4,251/oz in Q4-2025, and the impact of higher royalty rates following the increase in royalty rates from 6% to 8%), and a lower volume of gold sold.
• Sustaining capital expenditure decreased from $12.2 million in Q4-2025 to $6.2 million in Q1-2026 and was primarily related to land compensation and waste stripping activities at the Le Plaque pit.
• Non-sustaining capital expenditure decreased slightly from $5.3 million in Q4-2025 to $5.2 million in Q1-2026 and was primarily related to the TSF 2 stage 3 embankment raise.

• Ity is on track to achieve its FY-2026 production guidance of 285koz – 330koz, at an AISC within the guided $1,300/oz – $1,500/oz range, when adjusted for the impact of higher gold prices on royalty costs (+$158/oz impact Q1-2026 due to the realised gold price of $4,770/oz, compared to the guidance gold price of $3,000/oz).
• During the remainder of FY-2026, ore is expected to be sourced from the Bakatouo, Le Plaque, Flotouo West, Verse Ouest and Zia pits. Average grades processed are expected to increase in line with higher grades mined, while recovery is expected to remain consistent. Throughput is expected to increase due to an increase in mill availability related to the timing of planned CIL maintenance.
• Sustaining capital expenditure outlook for FY-2026 is in line with the previously guided $40.0 million, of which $6.2 million has been incurred in Q1-2026. FY-2026 sustaining capital expenditure is expected to primarily relate to pit de-watering, water treatment plant upgrades, processing plant critical spares and waste stripping at the Le Plaque and Zia pits.
• Non-sustaining capital expenditure outlook for FY-2026 is in line with the previously guided $45.0 million, of which $5.2 million has been incurred in Q1-2026. FY-2026 non-sustaining capital expenditure is expected to primarily relate to processing plant upgrades, land compensation and site establishment at the Gbeitouo deposit, and the stage 3 embankment raise at the TSF 2.

• Production decreased from 46koz in Q4-2025 to 39koz in Q1-2026 due to lower tonnes of ore milled, lower grades processed and lower recoveries.
  • Total tonnes mined and ore tonnes mined decreased due to the reduction in mining activities at the Siou underground mine as well as reduced blasting efficiency at the Wona underground mine.
  • Development rates across the Siou and Wona underground deposits amounted to 2,728 metres, a decrease from the 4,521 metres completed in the prior quarter, as development activities at the Siou underground mine were completed, and stoping activities at the Wona underground mine were prioritised.
  • Tonnes milled decreased due to lower mill utilisation compared to the prior quarter as a result of lower ore tonnes mined.
  • Average grades processed decreased due to lower grade ore sourced from the Wona underground deposit and a lower proportion of higher grade ore sourced from the Siou underground.
  • Recovery rates decreased due to a higher proportion of ore sourced from the Wona underground deposit with lower associated recovery rates.
• AISC increased from $2,174/oz in Q4-2025 to $2,552/oz in Q1-2026 due to higher royalties related to the higher realised gold price (+$117/oz impact due to the realised gold price of $4,849/oz compared to the realised gold price of $4,236/oz for Q4-2025), lower volumes of gold sold, and higher power unit costs due to the elected reliance on self-generated power at higher unit cost, partially offset by lower sustaining capital expenditure.
• Sustaining capital expenditure decreased from $17.8 million in Q4-2025 to $13.9 million in Q1-2026 and was primarily related to capitalised underground development at the Wona underground deposit, as well as lease payments for contractor mining equipment.
• Non-sustaining capital expenditure decreased from $1.7 million in Q4-2025 to $1.1 million in Q1-2026 and was primarily related to underground infrastructure upgrades and the stage 6 embankment raise at the TSF.

• Mana is on track to achieve its FY-2026 production guidance of 155koz – 180koz at an AISC within the guided $2,000/oz – $2,250/oz range, when adjusted for the impact of higher gold prices on royalty costs (+$304/oz) due to the realised gold price of $4,849/oz.
• During the remainder of FY-2026, ore is expected to be sourced from the Wona underground deposit with total tonnes and ore tonnes mined expected to increase in the remaining quarters, with operations at the Siou underground mine now complete following the depletion of the mineral reserve. Milled grades are expected to increase in line with the higher proportion of stope tonnes mined, whilst mill throughput will increase in line with the supplementary feed from the Bana Camp open pit deposit in the mill feed. Recoveries are expected to remain consistent.
• Sustaining capital expenditure outlook for FY-2026 remains unchanged at $60.0 million, of which $13.9 million has been incurred in Q1-2026. FY-2026 sustaining capital expenditure is expected to primarily relate to waste development in the Wona underground deposit as well as processing plant and infrastructure upgrades.
• Non-sustaining capital expenditure outlook for FY-2026 remains unchanged at $10.0 million, of which $1.1 million has been incurred in Q1-2026. FY-2026 non-sustaining capital expenditure is expected to primarily relate to the ongoing stage 6 embankment lift at the TSF.

• Production decreased from 78koz in Q4-2025 to 67koz in Q1-2026 due to lower average grades processed, partially offset by higher tonnes milled, while recovery rates remained stable.
  • Total tonnes mined increased due to improved pit conditions following the end of the wet season, which extended in to the prior quarter. Ore for the CIL plant was primarily sourced from the Niakafiri West, Delya Main, Niakafiri East, Delya South and Soukhoto pits, while ore for the BIOX plant was primarily sourced from the Massawa Central Zone.
  • Total tonnes milled increased through both the CIL and BIOX plants due to a higher proportion of oxide ore from Delya South in the CIL processing plant feed and improved availability in the BIOX processing plant following the completion of planned maintenance during the prior quarter.
  • Average processed grades decreased through both the CIL and BIOX plants due to lower average grade ore sourced from the Niakafiri West, Massawa Central Zone and Delya Main pits, partially offset by higher grade ore sourced from the Soukhoto, Delya South and Niakafiri East pits.
  • Recovery rates remained stable as the decrease in the CIL processing plant, due to a higher proportion of oxide ore with lower associated recoveries in the mill feed, was fully offset by an increase in recovery rates in the BIOX processing plant, due to operational control of the floatation and gravity circuits.
• AISC increased from $1,237/oz in Q4-2025 to $1,372/oz in Q1-2026 due to lower gold sales, higher royalty costs related to the higher realised gold price (+$27/oz impact for Q1-2026 due to the realised gold price of $4,881/oz, before the impact of the Sabodala-Massawa stream, compared to the realised gold price of $4,222/oz for Q4-2025) and higher sustaining capital, partially offset by a decrease in BIOX processing unit costs following planned maintenance performed in the prior quarter.
• Sustaining capital expenditure increased from $5.4 million in Q4-2025 to $9.6 million in Q1-2026 and was primarily related to waste development at the Delya Main, Delya South and Massawa Central Zone pits as well as mining equipment rebuilds.
• Non-sustaining capital expenditure decreased from $12.9 million in Q4-2025 to $6.3 million in Q1-2026 and was primarily related to BIOX gravity circuit and cyclone upgrades, processing plant upgrades and waste development at Soukhoto.

• Sabodala-Massawa is on track to achieve it’s FY-2026 production guidance of 260koz – 305koz, at an AISC within the guided $1,350/oz – $1,550/oz range, when adjusted for the impact of higher gold prices on royalty costs (+$106/oz impact YTD-2026 due to the realised gold price of $4,881/oz, before the impact of the Sabodala-Massawa stream, compared to the guidance gold price of $3,000/oz).
• During the remainder of FY-2026 ore for the CIL plant will be primarily sourced from the Niakafiri East, Niakafiri West, Delya Main and Delya South pits with supplementary ore from the Samina pit and stockpiles. Higher average grades and recovery rates, due to higher grade mined, are expected to be offset by slightly lower throughput rates resulting in stable performance from the CIL plant through the year.
• During the remainder of FY-2026 ore for the BIOX plant will continue to be sourced from the Massawa Central Zone pit. Throughput, average grades and recovery rates are expected to progressively improve due to an increased proportion of fresh ore in the mill feed and ongoing optimisation of the processing plant.
• Sustaining capital expenditure outlook for FY-2026 remains unchanged at $50.0 million, of which $9.6 million has been incurred Q1-2026. FY-2026 sustaining capital expenditure is expected to primarily relate to capitalised waste stripping, mining fleet upgrades and process plant maintenance.
• Non-sustaining capital expenditure for FY-2026 remains unchanged at $30.0 million, of which $6.3 million has been incurred in Q1-2026. FY-2026 sustaining capital expenditure is expected to primarily relate to pre-stripping at the Kiesta C deposit, implementation of a fleet management system, mining readiness, the embankment raise at TSF 1 and advanced grade control drilling activities.

• The Group published an NI 43-101 Technical Report for the Sabodala-Massawa mine on 30 March 2026, which can be accessed on Sedar+ and on Endeavour’s website.
• The Technical Report included a revised life-of-mine production profile based on the Proven and Probable reserves, as at 31 December 2025, only. This production profile is expected to be supplemented through resource conversion and exploration.
• The Technical Report highlights that the production profile at Sabodala-Massawa over the next five years is expected to increase towards 391koz of annual production in 2029 supported by the commencement of underground mining at the high-grade Kerekounda and Golouma deposits providing high grade feed for the CIL processing plant, as well as the introduction of high-grade refractory ore from the Massawa North Zone deposit, supporting higher grade feed for the BIOX processing plant.
• Based on the Technical Report, over the five years from 2027 to 2031, average annual production of 335kozpa is expected, and over the remaining life-of-mine average annual production of 254kozpa is expected. This production profile excludes the impact of resource to reserve conversion and the impact of any optimisation to the mining sequence that could help smooth out the production profile.
• The Golouma and Kerekounda underground deposits are expected to supplement CIL processing plant production from FY-2027 through FY-2032, providing high grade ore. Underground mine development is expected to commence in H2-2026 with a non-sustaining capital spend of $25m for FY-2026 as previously guided. The underground is expected to achieve commercial production in FY-2028.

• Production increased from 53koz in Q4-2025 to 56koz in Q1-2026 due to an increase in average grades milled, recovery rates and tonnes milled.
  • Total tonnes mined increased due to improved contractor performance achieving higher fleet availability. Total ore tonnes mined decreased due to an increase focus on waste stripping related to a phased pushback at the Main pit, in line with mine sequence.
  • Total tonnes milled increased due to higher mill availability and utilisation following planned HPGR maintenance that occurred during the prior quarter.
  • Average processed grades increased due to higher average grades mined from the Main pit, partially offset by lower average grades mined from the West pit, in line with mine sequence.
  • Recovery rates increased due to higher grades processed through the processing plant and optimisation of the regeneration kiln improving carbon reactivation.
• AISC increased from $1,476/oz in Q4-2025 to $1,811/oz in Q1-2026 due to higher sustaining capital related to waste stripping, higher royalties related to the higher realised gold price (+$141/oz impact for Q1-2026 due to the higher realised gold price of $4,887/oz, compared to the realised gold price of $4,207/oz for Q4-2025 and the impact of higher royalty rates following the increase in royalty rates from 6% to 8%), and the drawdown of stockpile inventory, partially offset by a decrease in mining unit costs due to lower blasting volumes and lower grade control meters drilled, while processing unit costs decreased due to HPGR maintenance which was performed in Q4-2025.
• Sustaining capital expenditure increased from $2.9 million in Q4-2025 to $28.7 million in Q1-2026 and was primarily related to the phased pushback at the Main pit.
• Non-sustaining capital expenditure decreased from $4.5 million in Q4-2025 to $3.5 million in Q1-2026 and was primarily related to the stage 2 embankment lift at the TSF and advanced grade control drilling.

• Lafigué is on track to achieve its FY-2026 production guidance of 170koz – 195koz at an AISC within the guided $1,600/oz – $1,800/oz range, when adjusted for the impact of higher gold prices on royalty costs (+$123/oz impact due to the realised gold price of $4,887/oz compared to the guidance gold price of $3,000/oz).
• During the remainder of FY-2026, ore is expected to be primarily sourced from the Main pit pushback supplemented by ore from the West pit pushback, whilst pre-stripping activities are expected to commence at the next pushback at the Main and West pits in H2-2026. Average processed grades are expected to decrease while recovery rates are expected to remain stable following the completion of mining of high grade domains within the Main pit during Q1-2026. This will be partially offset by increased throughput rates due to ongoing crusher optimisation, with the plant expected to consistently outperform design nameplate.
• Sustaining capital expenditure for FY-2026 remains unchanged at $30.0 million, of which $28.7 million has been incurred in Q1-2026 with the limited remainder of FY-2026 expenditure primarily related to strategic spares for the crushing circuit.
• Non-sustaining capital expenditure for FY-2026 remains unchanged at $90.0 million, of which $3.5 million has been incurred in Q1-2026, with FY-2026 expenditure primarily related to pre-stripping activities at the Main pit, TSF embankment lift stages 3 and 4, advanced grade control drilling and processing plant upgrades.

• As published on 23 April 2026, Endeavour announced positive definitive feasibility results (“DFS”) for the Assafou project. The DFS highlights 320kozpa production at AISC of $1,026/oz over the first 8 years, with a 16 year life-of-mine.

• The project boasts robust economics, outlined in table 17, with an after-tax NPV_5% of $5,113.0 million and after-tax IRR of 55% at a $4,000/oz gold price.

• The Assafou DFS envisages a scalable 5.0Mtpa gravity / CIL processing plant, with project upfront capital of $1,061.0 million. The increase in upfront capital is related to scope changes to infrastructure as well as plant optimisations, scalability and ramp-up de-risking.
• Growth capital guidance in FY-2026 for early works prior to the final investment decision of $50.0 – 100.0 million, out of the upfront capital of $1,061.0 million.
• Following the announcement of the DFS, the next steps to progress the Assafou project to production are as follows:
  • Q2-2026: Procurement of long-lead items has been launched.
  • Q2-2026: Detailed engineering and design is underway.
  • Q2-2026: EPCM, power and earthworks tender reviews are advancing towards finalisation.
  • Q2-2026: Development of the relocation action plan is underway to support the resettlement and discussions with the affected communities are expected to conclude by year end.
  • Q3-2026: Mining convention negotiations are underway with an expected completion in Q3-2026.
  • Late-2026: Final investment targeted before end of FY-2026, following the final investment decision, construction is expected to start.
• The resettlement action plan is being developed to support the resettlement. Negotiations with villages within the resettlement plan, and for the proposed new village host sites, including with respect to land and crop compensations, are underway. The completion of the resettlement action plan and the subsequent resettlement are required, prior to the commencement of mining activities. As a result the resettlement, in addition to mining pre-stripping and process ore commissioning, are on the project’s critical path.
• The Technical Report will be published within 45 days of the Assafou DFS news release, which was published on 23 April 2026. The DFS aligns to the NI 43-101 Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards of a Feasibility Study, in line with Endeavour’s technical disclosure and reporting requirements. The “Definitive” classification is not a prescriptive classification.

• Since 2016, Endeavour’s exploration programme has discovered 22.4Moz of M&I resource for a discovery cost of less than $25/oz, sustainably replacing production depletion, extending mine lives, and adding two cornerstone assets to the portfolio.
• Following the success of the 2016 – 2025 Exploration Strategies, in December 2025 the Group launched its 2026 – 2030 Exploration Strategy to discover between 12-15 million ounces of Measured, Indicated and Inferred resources for a sector leading discovery cost of less than $40 per ounce. In addition to replacing production depletion, exploration will be focused on expanding and diversifying the greenfield pipeline both within the West African portfolio and within three highly fertile, geologically immature, tier 1 gold provinces; the Central Asian Orogenic Belt, the West Tethyan Metallogenic Belt and the Guiana Shield, through Endeavour’s New Venture programme.
• During FY-2026, an extensive $100.0 million exploration programme is planned of which $18.1 million has been spent in Q1-2026 and a total of 19,000 metres of drilling was completed. During the remainder of the year exploration activities will prioritise replacing production depletion across the operating portfolio as well as targeting, scoping and resource definition across the greenfield portfolio.

• An exploration programme of $10.0 million is planned for FY-2026, of which $2.2 million was spent in Q1-2026 consisting of over 5,100 metres of drilling across 10 drill holes.

• An exploration programme of $15.0 million is planned for FY-2026, of which $4.4 million was spent in Q1-2026 consisting of over 2,500 metres of drilling across 667 drill holes. The FY-2026 programme remains focused on supporting the medium-term production profile through exploration for near-mine non-refractory resources.
• During Q1-2026, exploration activity primarily focused on drilling at the Makana and Kawsara targets, as well as drill testing the historic Sofia and Sabodala pits to identify resource extensions at depth. In addition, AI supported exploration targeting across the Sabodala-Massawa permit area, has identified and ranked 24 targets for follow up, based on a prospectivity model developed using the Sabodala-Massawa mineralisation model.
• During the remainder of the year, the exploration programme will continue to focus on non-refractory targets to support the medium-term production profile including the Makana and Kawsara targets, as well as definition of the long-term targets along the Kawsara extension. AI generated targets will be systematically evaluated through the year through geological mapping, sampling and reconnaissance drilling.

• An exploration programme of $10.0 million is planned for FY-2026 focused on delineating resources at near-mine targets 1 and 12. Drilling activities are expected to commence in Q2-2026.
• During the remainder of the year, the exploration programme will focus on resource definition at these near-mine targets, including Target 1 where initial drilling results have identified higher-grade continuous mineralisation along shear zones.

• An exploration programme of $10.0 million is planned for FY-2026, of which $0.2 million was spent in Q1-2026 consisting of over 1,100 metres of drilling across 8 drill holes. The FY-2026 programme remains focused on extending resources at the Pala Trend 3 discovery, defining resources at Pala Trend 2 and Pala Trend Southwest targets, and delineating several high potential brownfield targets within 10km of the Assafou deposit including the Koumenagaré target.
• During Q1-2026, exploration activity primarily focused on trenching and drill testing soil geochemical anomalies at the Koumenagaré target. Drilling returned narrow zones of high-grade mineralisation in quartz veined zones of sericite and pyrite alteration.
• During the remainder of the year, the exploration programme will continue to delineating resources at the Pala Trend targets, with maiden resources at Pala Trend 2 expected this year. High potential brownfield targets within 10km of the Assafou deposit will continue to be tested to prioritise these targets for follow up drilling campaigns.

• The New Ventures and greenfield exploration programme is focused on expanding and diversifying the long-term organic growth pipeline through its operated greenfield exploration programmes, and by leveraging early stage exploration companies operating in highly prospective, immature, tier 1 gold provinces.
• Koulou Gold Corp – Côte d’Ivoire: On 14 April 2026, Koulou Gold Corp (“Koulou”) announced a private placement for gross proceeds of $30.0 million through the issuance of 35.7 million shares. Endeavour increased its ownership in Koulou to 19.9%, subscribing to 8.1 million shares.
  • On 9 February 2026, Koulou Gold announced the acquisition of the highly-prospective Koun-Fao permits, PR1019 and PR1022, totalling 601.9 km², that are located immediately south of the Assafou and Assuéfry permits along similar structural trends as those seen at Assafou and Assuéfry, and underlain by similar Tarkwaian-like Koun Tanda Basin sediments and Birimian volcanic rocks, with historical gold occurrences highlighting their prospectivity. Koulou Gold holds an option to earn up to 100% interest in these exploration permits.
• Altair Minerals Limited – Guyana: On 27 April 2026, Altair Minerals Limited (“Altair”) announced a strategic investment by Endeavour, via a non-brokered private placement, for 9.9% ownership. Endeavour subscribed to approximately 656 million shares priced at AUD0.043/sh, a 5% premium to Altair’s closing price on 24 April 2026.
  • The investment forms part of Endeavour’s 2026-2030 Exploration Strategy that is focussed on replacing production depletion and adding new greenfield opportunities in highly prospective tier 1 gold provinces with low exploration maturity. The Guiana Shield is the western extension of the West African Craton, hosting multiple greenstone belts with proven orogenic gold systems, analogous to West Africa’s Birimian belt.
  • Endeavour will leverage its exploration expertise from West Africa, by establishing a joint technical committee with Altair following the transaction to support Altair’s expedited early-stage exploration programme. Altair operates the recently consolidated Greater Oko land package, which is the largest consolidated exploration land package in Guyana at 590km², located immediately adjacent to the Oko West (80.3Mt at 2.10g/t for 5.4Moz M&I resources) and Oko-Ghanie (15.6Mt at 3.24g/t for 1.6Moz M&I resources) discoveries. Altair is advancing several highly prospective targets on the Greater Oko land package, including the W1, W2, W3 and S1 and S2 targets on the South Oko prospect, which is the southern continuation of the Oko Shear Zone.
  • Proceeds from the strategic investment will be used to: 1) Increase the current drill programme to 50,000 metres, including at least 30,000 metres at the South Oko prospect, 2) Accelerate the geochemical sampling programme at the South Oko prospect, and; 3) Launch a regional exploration programme across the land package.
  • Guyana is one of the fastest growing economies in the world with a GDP growth rate of 10.3% for 2025, driven by growth in crude oil production, which commenced in 2019. Guyana is also a mining friendly jurisdiction, ranked 1^st in Latin America and 10^th globally for mining investment attractiveness by the Fraser Institute with a straightforward mining permitting process, transparent fiscal terms and it operates under a British parliamentary system.
