Q1 2026 Activities Report
For the Quarter ending 31 March 2026 ('Q1', 'March Quarter' or 'the Quarter')
Quarterly Highlights
• Total Recordable Injury Frequency Rate (TRIFR) of 0.43 with only one recordable injury during Q1
• Group gold production of 59,603 ounces (oz) (Q4 2025: 65,918oz) in line with expectations at both Mako (Senegal) and Syama (Mali)
• All-In Sustaining Costs (AISC) of $2,210/oz (Q4 2025: $1,877/oz) in line with guidance as cost reductions partially offset higher royalty payments due to record average realised gold prices
• Capital expenditure of $33.4 million (Q4 2025: $28.7 million) consisting of $14.3 million non-sustaining, $6.9 million of sustaining, $5.1 million exploration capital spend, $7.1 million at Doropo and Mako Life Extension Project (MLEP). Remains on track with guidance ($310 - 360 million)
• Operating cash flow generation of $119.8 million (Q4 2025: $85.7 million) (operating cash flow before capital expenditure, exploration and working capital)
• EBITDA of $202.9 million (Q4 2025: $104.9 million); $337.6 million revenue (Q4 2025: $201.5 million)
• Net cash of $315.4 million (Q4 2025: $209.0 million), including cash, cash equivalents and bullion of $327.6 million. Drawn overdraft balances and equipment financing were $12.2 million
• Proceeds of $31.9 million received from the sale of Resolute's stake in Loncor Gold
• Key milestones reached at the Doropo Project (Côte d'Ivoire) including receipt of the mining permit and formal approval of Final Investment Decision (FID)
• Strategic Memorandum of Understanding (MoU) signed with Nimba Mining Company regarding the potential co-development of gold projects in Guinea
• Ore Reserves and Mineral Resource Statement for 31 December 2025 published:
• Total Mineral Resources increased by 60% to 17.6 Moz Au with the acquisition of the Doropo and ABC projects and exploration success at Bantaco and La Debo
• Total Ore Reserves increased by 55% to 6.8 Moz Au with the addition of Ore Reserves at Doropo and Tomboronkoto offsetting mining depletion in Mako and Syama
• Promising drill results at ABC Project (Côte d'Ivoire) including 73m at 0.8 g/t Au from 2m along strike of the existing MRE at Kona South
• Scoping Study for the ABC Project remains on track for completion in Q2 2026
• On track to meet production guidance of 250 - 275 koz. Group AISC of $2,000 - 2,200/oz is maintained, however is subject to change at current elevated gold prices and higher fuel costs
Note: Unless otherwise stated, all dollar figures are United States dollars ($). AISC guidance is based on $4,000/oz gold price.
Resolute Mining Limited (Resolute, the Company or the Group) (ASX/LSE: RSG), the West Africa-focused gold miner, is pleased to present its Quarterly Activities Report for the period ended 31 March 2026.
Chris Eger, Chief Executive Officer, commented,
"It has been a positive start to 2026 at both our operations and at our development and exploration projects.
Our operations continued to perform in line with expectations and generated $119.8 million of operating cash flows helping boost our net cash position to $315.4 million. We remain on track with production guidance which is weighted to H2 as the Syama Sulphide Conversion Project is commissioned and ramps up.
In Cote d'Ivoire we have had a very successful Quarter at ABC and Doropo. At ABC we have been focusing on strike extensions of the Kona South and Central deposits that have an existing MRE of 2.2 Moz. With the success we have been seeing at ABC, including an intercept from surface of 73 m grading 0.8 g/t, we will continue drilling in order to further expand resources. During Q1 we started a scoping study for ABC, based on the existing MRE, which we expect to release in Q2. At Doropo we achieved two major milestones: receipt of our mining permit and formal approval of FID. In April ground clearance activities started and we remain on track for first gold in H2 2028.
In Senegal, stockpile processing at Mako continued to perform extremely well. Additionally, strong progress was made on technical and permitting workstreams for the MLEP. Internal technical studies currently indicate annual gold production levels of 75 - 85 koz over seven years from the Tomboronkoto and Bantaco deposits at a capital cost of between $125 - 150 million. We are continuing with optimizations and are confident of further improvements to the project.
During the Quarter we also signed a strategic MoU with Nimba Mining Company to evaluate projects in Guinea. This aligns with Resolute's strategy of building a pipeline of high-quality growth opportunities in established West African gold jurisdictions and complements our other activities in Guinea.
While the ongoing situation in the Middle East has not resulted in any direct disruptions to our supply chain, we are closely monitoring developments. There is a potential for increased AISC due to rising fuel prices, which could impact our operational costs in the coming quarters. At this stage, we are proactively managing these risks and, where possible, minimizing any impacts.
Overall, I am pleased with the Group's activities and financials in Q1. We remain confident in delivering against our guidance, supported by a robust balance sheet and experienced teams, that are well placed to continue performing across the business as we move into Q2."

| Notes to Accompany Table: |
| •Grid coordinates are WGS84 Zone 29 North |
| •RC intervals are sampled every 1m by dry riffle splitting or scoop to provide a 2-3kg sample |
| •Cut-off grade for reporting of intercepts is >0.5g/t Au with a maximum of 3m consecutive internal dilution included within the intercept; only intercepts =>3m and >15 gram x metres are reported |
| •Recent drill samples are analysed for gold by MSA Labs CPA-Au1 500g sample gamma ray analysis by photon assay instrument |
| Criteria | JORC Code explanation | Commentary |
| Sampling techniques | • Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. • | • The sampling was conducted using multiple techniques tailored to the project's geological and surface conditions. A systematic rock sampling program was caried out in 2017 to fully characterise the surface expression of the mineralisation. A total of 788 rock samples were collected in 2017 and 205 rock samples in 2019/2020. • Auger drilling was employed extensively over the mineralised corridor to adequately characterise the underlying rocks. Auger drilling recovered material systematically for gold analysis and geochemical interpretation. As with the rock chips, auger samples were analysed for Au by fire assay with AAS finish at Bureau Veritas in Abidjan. Multi-element analyses were completed by four-acid digest with ICP-AES and ICP-MS finish at ACME Laboratories in Vancouver. A total of 2,843 samples were collected at the end of 2020 from 22,219m drilled. • Reverse Circulation (RC) and Diamond Core (DD) drilling were the principal methods used for delineating Mineral Resources. RC drilling was conducted using 5¼ to 5¾ inch diameter face-sampling hammers to recover one-metre interval samples, typically dry unless groundwater was encountered. Diamond drilling employed HQ and NQ diameter core, with triple tube techniques for improving recovery in broken ground. RC samples were riffle split on site, and core samples were sawn to produce half-core for analysis. Sampling procedures incorporated QAQC measures, including the insertion of blanks, standards, and duplicates to ensure sample representivity. Assay protocols utilised 50 g fire assay (AAS finish) for gold, and multi-element analysis was performed where applicable. |
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). | • Drilling methods involved a combination of Reverse Circulation (RC), Diamond Core (DD), and auger drilling methods. RC drilling was primarily used for delineating near-surface mineralisation and preliminary resource definition. RC drilling employed face-sampling hammers with bit sizes ranging from 5¼ to 5¾ inches. Dry drilling was the standard procedure, with drilling halted at the water table to prevent contamination from wet samples; below groundwater, diamond drilling methods were applied. • Diamond core drilling used HQ and NQ diameter core. Triple-tube systems were implemented in highly broken ground to maximise core recovery, while standard double-tube setups were used elsewhere. Downhole surveys are taken every 30m with a single shot Reflex EZ shot system. Orientation of diamond core was conducted selectively using Reflex ACT II core orientation devices to facilitate structural logging. Auger drilling was utilised for shallow exploration across the entire area. All drill methods were executed to a high standard with contractors experienced in gold exploration in West Africa. • |
| Drill sample recovery | • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. | • Drill sample recovery was systematically monitored during both RC and diamond drilling programs. RC samples were weighed regularly, to monitor sample size consistency and ensure the representativeness of samples. Analysis of sample weights of 47,562 RC samples from Kona South and 47,464 RC samples showed a consistent recovery trend stabilizing between 30-40 kg per metre after clearing the uppermost weathered horizons. Minor variations in sample weight were observed at shallow depths and in softer materials; however, statistical checks confirmed no significant bias in gold grade associated with sample mass. • Diamond core recovery was measured, with an overall average recovery of approximately 96% across the project. Recovery rates improved with depth, with 81% core recovery in oxide, 91% recovery in transitional and 99% in fresh. Core recovery measurements were recorded in the database for each run. The use of triple-tube drilling in broken ground contributed to maintaining high recovery standards. The overall conclusion, supported by quality control reviews, was that there is no significant sampling bias attributable to differential recovery. |
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. | • Comprehensive geological and geotechnical logging was undertaken for all drillholes including RC and DD. Drillholes were logged systematically for a range of key geological attributes: lithology, alteration, mineralisation, texture, structure, weathering, and rock quality designation (RQD). RC samples were logged visually on site, with geological observations recorded both digitally and on physical log sheets where applicable. Diamond core was logged in greater detail, particularly for structural geology, alteration styles, mineral assemblages, and vein relationships, providing critical inputs for 3D geological modelling. • Photographic records were maintained for all diamond drill core - photographed both wet and dry - before sampling. Logging captured sufficient detail to support resource estimation, mining studies, and metallurgical investigations. Logging procedures included the use of a standardised lithological and alteration coding scheme to ensure consistency across the drilling campaigns. Digital capture of logging data into a centralised database with validation rules also enhanced data reliability. |
| Sub-sampling techniques and sample preparation | • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. | • Systematic sub-sampling and sample preparation protocols were employed to ensure that samples remained representative of in situ mineralisation. For RC drilling, 1 m samples were split on site using a three-tier riffle splitter to achieve a target sample size of approximately 2 to 3 kg for laboratory submission. Wet samples encountered in shallow zones were left to dry naturally prior to splitting where possible. For diamond drilling, core was cut lengthwise using diamond-bladed core saws; half-core samples were collected for routine assay, while the other half was preserved for reference and potential future re-assay. • Sample preparation at the laboratory followed industry best practices. Samples were oven dried, crushed to 70 to 85% passing 2 mm, then riffle split to produce a subsample for pulverisation. The pulverised material was milled to achieve at least 85% passing 75 microns, producing a pulp of approximately 150 to 250 g for fire assay analysis. Quality assurance measures were built into preparation workflows, including the regular inclusion of duplicate splits and check samples. Laboratory facilities used (primarily Bureau Veritas Abidjan, SGS Ouagadougou) operated to ISO 17025 standards, and internal laboratory QAQC reviews were conducted regularly. More recent Au analyses were conducted by Chrysos Photon assay at MSA labs in Yamoussoukro. Laboratory and assay procedures are appropriate for Mineral Resource estimation |
| Quality of assay data and laboratory tests | • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. • | • Assay methodologies were based on internationally recognised standards and utilised reputable laboratories. All drill samples were primarily analysed for gold using 50 g fire assay with atomic absorption spectroscopy (AAS) or inductively coupled plasma atomic emission spectroscopy (ICP-AES) finish. In cases where assays exceeded 10 g/t Au, samples were re-analysed using a gravimetric finish to improve accuracy. For some RC and trench samples, particularly those with coarse gold. • Quality control procedures were rigorous. Certified reference materials (standards), field blanks, and field duplicates were inserted into the sample stream at regular intervals - approximately one QAQC sample every 20 to 30 samples. Laboratory duplicates, internal standards, and blanks were also monitored. QAQC data were routinely reviewed to ensure analytical accuracy and precision. Failures (e.g., a standard outside 3 standard deviations) triggered immediate re-assay of sample batches. No significant long-term bias or drift was observed across the assay dataset. Laboratories involved (Bureau Veritas, Abidjan; MSA Yamoussoukro; and SGS, Ouagadougou) are ISO/IEC 17025 accredited, ensuring laboratory practices are consistent with industry best practice. |
| Verification of sampling and assaying | • The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. | • Verification of sampling and assaying was undertaken through a combination of internal reviews, duplicate analyses, and independent data validation exercises. Field duplicates were collected regularly from RC drilling to monitor sampling precision, with results demonstrating satisfactory repeatability of gold grades. CRMs and blanks were inserted at regular intervals to monitor assay accuracy and contamination. QAQC charts were reviewed continuously by project geologists and external consultants during key drilling campaigns. • The primary assay laboratories (Bureau Veritas and SGS) conducted their own internal QC programs, which were also monitored. Limited twin drilling was conducted, with twin RC holes and DD holes used to verify mineralisation continuity, grade reproducibility, and geological interpretation; results confirmed good spatial reproducibility. While external umpire (secondary lab) assay programs were not routinely undertaken, the performance of primary laboratories and internal QAQC programs were considered satisfactory for the reporting of Mineral Resources. Assay data and logging data were entered digitally into validated databases, and independent audits of the database have been performed during resource estimation reviews. |
| Location of data points | • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. | • Drillhole collar locations were surveyed using a combination of differential GPS (DGPS) systems and total station surveying where higher precision was required. The DGPS surveys were conducted by trained field surveyors to ensure location accuracy suitable for Mineral Resource estimation, with horizontal and vertical accuracy generally within ±0.2 m. In areas of rugged topography or logistical difficulty, survey-grade handheld GPS units were temporarily used during initial exploration stages (rock sampling, auger drilling), but were later replaced with DGPS surveys for all critical drill collars. • Elevation data were tied into the Nivellement Général de Côte d'Ivoire (NGCI) vertical datum. A topographic digital terrain model (DTM) was produced using high-resolution satellite imagery and ground-truthing, which was used for resource modelling. Grid systems used were WGS84, Zone 29N for initial exploration and UTM Zone 29N (WGS84 projection) for final resource definition. |
| Data spacing and distribution | • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. | • Drilling was conducted on nominal grid spacings appropriate for the level of confidence required for resource estimation. In the main mineralised zones at Kona South and Kona Central RC and diamond drilling was performed on approximately 50 m x 50 m grids with some areas of wider spacing of 50m x 100m. • Outside the main resource areas, reconnaissance and exploration drilling was more broadly spaced at 50 m x 200 m intervals, appropriate for early-stage resource targeting. Data spacing was assessed during Mineral Resource Estimation and was found sufficient to establish geological and grade continuity for inferred classification. No sample compositing was applied prior to resource estimation; raw assay intervals were used directly in estimation procedures. |
| Orientation of data in relation to geological structure | • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. | • Drilling programs were designed to target mineralised structures as close to perpendicular as possible to the interpreted dip of mineralisation at each deposit. All drillholes were oriented towards the east with an inclination of -50° to -60°, depending on the local structural orientation of gold-bearing zones. The mineralisation is generally hosted in north trending structures dipping moderately to steeply to the west, making these drill orientations appropriate to intersect mineralised zones at reasonable angles and to minimise bias in the intercept lengths. • Geological interpretations and cross sections confirm that drilling achieved reasonably representative intersections of mineralisation. No significant sampling bias related to drilling orientation was observed during resource modelling and estimation. |
| Sample security | • The measures taken to ensure sample security. | • Sample security protocols were implemented to ensure the integrity of all collected samples from the point of collection through to laboratory delivery. After collection, samples were placed into pre-numbered, durable plastic bags and securely sealed. Multiple samples were then packed into larger polyweave sacks for easier handling and protection during transport. Samples were stored in a secure, supervised facility at the exploration camp before transportation. • Transport to the assay laboratories (Bureau Veritas in Abidjan and SGS in Ouagadougou) was carried out either by company personnel or trusted, contracted couriers. Chain-of-custody forms were maintained throughout the transfer process, and receipt of samples was acknowledged in writing by laboratory staff. While rigorous internal controls were observed, there is no specific mention of external audits or independent oversight of sample security protocols. However, no incidents of sample loss, tampering, or contamination have been reported, and laboratory reconciliation of received samples consistently matched dispatch records. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. | • Audits and reviews of sampling techniques, assay data, and database integrity have been carried out periodically. Internal technical reviews were performed by Centamin's in-house geology and resource teams throughout the exploration and resource evaluation phases. These reviews covered sampling practices, QAQC data performance, logging standards, and database quality, ensuring consistent application of protocols and identifying areas for procedural improvement where necessary. • Independent reviews of the Resource models and supporting exploration data were conducted as part of the NI 43-101 technical report preparation. Qualified Persons (QPs) signed off on the Mineral Resource estimates after assessing the drilling, sampling, and QAQC procedures. |

| Mineral tenement and land tenure status | • Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. | • The Kona South and Kona Central deposits are the most advanced prospects in Resolute's ABC Kona Project, which is located in the Kabadougou Region of the Denguélé District, in the northwest of Cote D'Ivoire. The Kona permit occurs approximately 600 km west of Resolute's Doropo Project and 540 km north-west of the capital city of Abidjan. The Kona permit is 100% owned by Centamin Cote d'Ivoire SARL, which is a 100% owned Ivoirian subsidiary of Centamin and covers an area of 382.9 km2. • All permits (Kona PR658, Windou PR877 and Farako Nafana) are held in good standing with the Côte d'Ivoire Ministry of Mines and have been maintained in accordance with local legal requirements. There are no known outstanding disputes affecting the licences and no known risks or environmental liabilities that could adversely affect or result in the loss of ownership of the Resource or permits. |
| Exploration done by other parties | • Acknowledgment and appraisal of exploration by other parties. | • Newmont are believed to be the first exploration company to explore the area in 2010. They conducted regional drainage sampling, mapping and prospecting across the entire district. This work highlighted the Kona area as one of their highest ranked targets. Local exploration companies, including Golden Oriole and Sani Resources, applied for exploration permits on the back of the Newmont reconnaissance licences but never raised the finance to conduct any significant work and subsequently had their permits revoked. • Centamin acquired the exploration permits from the government in 2015 to 2016. The 2018 Kona South Mineral Resource is the first defined in the area. There is no evidence of any illegal artisanal mining in the permit area. |
| Geology | • Deposit type, geological setting and style of mineralisation. | • The ABC Kona project is situated along the main Archean-Birimian Cratonic suture zone in western Côte d'Ivoire, specifically associated with the Sassandra Fault Zone. • The principal mineralised feature identified through mapping and sampling is the Lolosso structure, a north-south striking mineralised zone interpreted as a western splay off the major transcurrent Sassandra Fault. The geological setting includes a narrow keel of later Birimian volcano-sediments entrapped within earlier Archean thrusted granite and gneissic sheets, providing a complex structural and lithological host for mineralisation. • At Kona South, gold is predominantly hosted in psammitic units (north-south striking) dipping approximately 70° west. This unit is sandwiched between a calc-silicate hanging wall to the west and a paragneiss footwall to the east. An additional mafic volcanic unit lies west of the calc-silicate layer, completing the local stratigraphy. • The style of mineralisation is structurally controlled and shows a strong spatial association with arsenopyrite. Arsenopyrite occurs as disseminations and aggregates aligned with the foliation of the psammitic host. Strong silicification is evident within mineralised zones, though quartz veining is rare and does not appear to play a significant role in gold control. |
| Drill hole Information | • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: ◦ easting and northing of the drill hole collar ◦ elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar ◦ dip and azimuth of the hole ◦ down hole length and interception depth ◦ hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. | • The NI 43-101 Technical Report provides comprehensive drillhole information, covering collar locations, drill hole depths, azimuths, dips, and key intersections. Drillhole collars were initially surveyed using a handheld GPS, then independently surveyed using differential GPS (DGPS) or total station equipment. The collars are in the UTM Zone 29 North, WGS84 datum. The QP considered a drill plan and representative examples of drill sections through Kona South and Kona Central would be more informative than a tabulation of mineralised intercepts. Sections are provided in the report. • The database includes 388 drillholes for a total of 57,344 m of drilling. |
| Data aggregation methods | • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. | • Exploration results and Mineral Resource drill intercepts are reported based on compositing of contiguous mineralised intervals. Assay results were composited to 1m to ensure that sample length variability did not introduce bias. The average sample interval is 0.998m. • No metal equivalent values have been reported. • No top-cutting (grade capping) was applied when presenting raw exploration results; however, top-cutting was considered and applied during Mineral Resource estimation to control the influence of extreme outlier grades. Composites used downhole lengths of 1 m, reflecting the RC and DD sampling intervals. |
| Relationship between mineralisation widths and intercept lengths | • These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known'). | • The Kona Project drilling program was designed to optimise intersection angles relative to the interpreted orientation of gold mineralisation. Mineralisation typically occurs within steeply dipping shear zones striking north - south, dipping steeply ~70⁰ to the west. To account for this geometry, most drillholes were inclined at approximately -55° to -60° and drilled toward the east. This does result in intersections of the mineralisation at a high angle, and in general, true thickness is 80% of the sample length. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. | • The NI 43-101 Technical Report provides a variety of diagrams that illustrate the distribution of mineralisation, drill coverage and geological interpretation. These include: • Plan view maps showing drill hole collar locations and surface projections of the mineralised zones. • Cross sections and long sections through the deposits depicting lithological units, interpreted mineralisation wireframes, and drill intercepts. • Regional geological maps. |
| Balanced reporting | • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. | • Exploration results are presented in a manner that is consistent with balanced reporting principles. Both positive results (significant gold intersections) and lower-grade or barren drilling outcomes are discussed in the report narrative. • Resource estimation was based on all available drilling data, not just high-grade intervals. |
| Other substantive exploration data | • Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. | • The ABC Kona project has benefited from a broad range of exploration activities in addition to drilling. Centamin's exploration campaign included reconnaissance mapping and systematic rock chip sampling, auger sampling, ground geophysical survey, an airborne Magnetic and Radiometric survey as well as reverse circulation (RC) and diamond drilling. All the exploration work was conducted by Centamin personnel, or under their direct management, when carried out by contractors. • Preliminary, metallurgical test work has been carried out by Centamin, summarised in the report. • Bulk densities have been measured from drill core. • There are no known deleterious elements. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. | • Further work has been identified to support future exploration, evaluation, and potential development. Recommended activities include additional infill and extensional drilling aimed at converting Inferred Resources to Indicated and Measured categories, as well as to test mineralised structures beyond the current limits of resource models. Trenching to test new soil anomalies to identify additional targets. • More density testwork is required, specifically for the weathered portions of the Kona deposit to generate reliable density data. |

| Database integrity | • Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used. | • The drillhole database supporting the ABC Kona Resource estimate underwent a comprehensive validation process. Detailed checks were performed on collar coordinates, downhole survey measurements, lithology logs, and assay entries to ensure consistency and accuracy. QA/QC protocols were applied throughout the data collection and entry stages. • Only RC and DD were used for the Mineral Resource estimate. • The QP reviewed the validation and found no significant issues or errors that would materially affect the confidence in the database or the subsequent resource estimate. |
| Site visits | • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case. | • A formal site visit was conducted by the QP who undertook the MRE, on 29-30 August 2021, as part of the data verification program. The QP observed selected drill core, discussed geological framework and mineralisation controls, toured the camp facility, visited outcrops and checked several drill collar positions. He discussed data capture, storage and management. Particular attention was given to verifying geological logging, collar locations, sampling methods, and database integrity through comparison with field observations and logs. |
| Geological interpretation | • Confidence in (or conversely, the uncertainty of ) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The effect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling Mineral Resource estimation. • The factors affecting continuity both of grade and geology. | • The geological interpretation is based on geological mapping, drilling data (both RC and diamond core), assay results, and geophysical data. • The project area is located along the main Archean-Birimian Cratonic suture zone, the Sassandra Fault zone and hosts structurally controlled gold mineralisation. The geological model interprets mineralised zones as steeply dipping shear-hosted lodes, which are consistent with regional structural trends observed in comparable deposits throughout the belt. • At Kona South the gold is hosted almost entirely in the north-south striking psammite unit, dipping approximately 70° to the west. This unit is sandwiched between a calc-silicate unit to the west (hanging wall) and a paragneiss unit to the east (footwall). A further mafic volcanic unit abuts the hanging wall calc-silicate to the west, completing the Birimian inlier stratigraphy. • The interpretation of geology and mineralisation has been used to control the definition of wireframe solids for the mineralised wireframes, with mineralisation generally limited to the psammite units. • Mineralisation wireframes were modelled in Leapfrog using the Economic compositing function with the grade threshold of 0.2 to 0.3 g/t Au. 5 mineralised lodes were modelled in Kona South. • For Kona Central, numerous lodes were initially modelled and multiple interpretations considered. Ultimately a single bulk domain was modelled which captured all possible domain interpretations. An indicator kriging approach was undertaken to define the mineralised and unmineralised lodes, with a threshold applied at 0.25 g/t gold. |
| Dimensions | • The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. | • For Kona South, 5 lodes were modelled over a strike length of 3km trending towards NNW with a steep dip of 70⁰ towards the west. The major domains have a maximum extension down dip of 400 m to 0 mRL. • For Kona Central, the mineralised domain has a strike length of 2.4 km, with a maximum extension down dip of 400 m, to 0 mRL. • The plan width of the mineralisation ranges between 5 m and 40 m, depending on the domain and the density of drilling data. |
| Estimation and modelling techniques | • The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by-products. • Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. | • Software used for the Mineral Resource estimate included Leapfrog Geo, Surpac, Supervisor and Isatis. • The Mineral Resource estimation for Kona South used Ordinary Kriging (OK) followed by Uniform Conditioning (UC) and Localisation on SMU support (LUC). For Kona Central, Indicator kriging was performed to separate mineralisation from unmineralised material. Once domained, the estimation methods of OK into large panels (20 m x 20 m x 5 m), followed by UC and LUC into assumed SMU sized (5 m x 5 x 2.5 m) blocks. • Estimation domains were defined based on geological interpretations, including lithological and structural controls. Drillhole data was composited to 1 m intervals prior to estimation. Top-cuts were assessed and applied to 2 domains to mitigate the influence of high-grade outliers. In some areas a distance limiting constraint was applied. Variogram analysis was undertaken on normal scores transformed gold composites for each individual domain in both deposits. • The block models were constructed for each deposit with a parent block size of 5 m x 5 m x 2.5 m - the assumed SMU block size. The OK interpolation was undertaken into relatively large panel blocks - predominantly 20 m x 20 m x 5 m. • A two pass search strategy was employed, with increasing search radii and decreasing data requirements. • Grade control drill spacing and SMU block size were assumed for the process. • No production data exists to validate the estimate due to the project's exploration stage. • No by-products or deleterious elements were modelled. • Validation steps included visual comparison of block and composite grades, swath plots, and global statistical comparisons. |
| Moisture | • Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. | • Tonnages have been estimated on a dry basis. |
| Cut-off parameters | • The basis of the adopted cut-off grade(s) or quality parameters applied. | • The Mineral Resource estimates for the ABC Kona Project were reported using a 0.5 g/t Au cut-off grade. This cut-off was selected based on assumptions that reflect open pit mining methods, anticipated processing costs, metallurgical recoveries, and a long-term gold price assumption. |
| Mining factors or assumptions | • Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. | • Mining factors and assumptions are based on the expectation of open pit mining methods using conventional truck and shovel operations. • The Mineral Resource has been reported to a maximum depth of 250 m below surface. |
| Metallurgical factors or assumptions | • The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. | • Only limited metallurgical testwork has been conducted for the ABC Kona Project. A fresh sample composite of the Kona South was analysed by ALS Metallurgy Services in Augus 2018. The results indicate the Kona South material is hard, abrasive and non-refractory with an 88.9% overall Gravity-CIL gold recovery at P80 passing 75µm. • The mineralisation of Kona Central is analogous to Kona South and the metallurgical response is anticipated to be similar. Further test work is required. |
| Environmental factors or assumptions | • Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. | • No significant environmental issues are currently known. |
| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the different materials. | • Bulk density measurements were taken on drill core samples using water displacement methods to ensure accurate volume and mass measurements, accounting for any voids and porosity. Samples were taken from diamond drill core across lithologies and weathering profiles, although these were predominantly from fresh rock. Very little to no measured density values were available from transported, saprolite and partially oxidised zones. • 2,028 bulk density measurements were collected and statistically analysed. Density values were assigned to different oxidation domains based on the average density value. • The bulk density values assigned in the model are 2.01 g/cm³ for transported, 2.05 g/cm³ for oxide, 2.73 g/cm³ for saprolite, and 2.8 g/cm³ for fresh rock. |
| Classification | • The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriately reflects the Competent Person's view of the deposit | • The Mineral Resource has been classified and reported in accordance with the CIM Definition Standards. Resources were classified as the Inferred category based on a combination of drilling density, geological confidence, continuity of mineralisation, and data quality. • The drill spacing across the deposit is 40 m to 50 m. The QP states that the quality and veracity of the supporting data are of industry standard and the geological controls and continuity are reasonably well understood. However, the QP does not consider the current sample spacing sufficient to support confidence in the mineralised volume or grade continuity to classify with any greater confidence than Inferred. • The classification reflects the Qualified Person's view of the deposit. |
| Audits or reviews | • The results of any audits or reviews of Mineral Resource estimates. | • No independent audit has been completed on the ABC Korona Mineral Resource Estimate. • Cube undertook regular internal peer reviews during the course of the MRE work. |
| Discussion of relative accuracy/ confidence | • Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. • The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used. • These statements of relative accuracy and confidence of the estimate should be compared with production data, where available. | • The relative accuracy and confidence of the ABC Kona Mineral Resource estimates are considered appropriate for the classification level assigned. • No production data is available for direct reconciliation, as the project is still in the exploration and development phase. • At the global scale, the Mineral Resource estimate is considered to have an accuracy commensurate with industry expectations for a project at the advanced exploration stage. |
