·    The sampling was conducted using multiple techniques tailored to the project's geological and surface conditions. Soil sampling programs were extensive, collecting approximately 92,307 samples between 2014 and 2022. Soils were sampled from the mottled zone or the top of the saprolite horizon to obtain coherent gold anomalies, utilising standardised grid patterns (typically 400 m x 400 m, with infill at 200 m and 100 m where required). Auger drilling was employed in areas with thick lateritic cover (>3 m), reaching saprolitic material with depths averaging 6.22 m and up to 30 m in some cases. Auger drilling recovered material systematically for gold analysis and geochemical interpretation.

·    Trenching programs (32 trenches to date) were used to expose in situ mineralised structures, allowing for systematic channel sampling.

·    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 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. 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 areas with thick laterite cover. All drill methods were executed to a high standard with contractors experienced in gold exploration in West Africa.

·    Drill sample recovery was systematically monitored during both RC and diamond drilling programs. RC samples were weighed regularly, particularly from 2018 onwards, to monitor sample size consistency and ensure the representativeness of samples. Analysis of over 447,401 RC sample weights 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 >90% core recovery recorded for 89.5% of core samples, and exceeding 97.5% recovery below 50 m depth. 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.

·    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.

·    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.

·    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, photon assay techniques were trialled to validate fire assay results.

·    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 and SGS, Ouagadougou) are ISO/IEC 17025 accredited, ensuring laboratory practices are consistent with industry best practice.

·    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.

·    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 (soil sampling, auger drilling, trenching), 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 both resource modelling and mine planning. Grid systems used were WGS84, Zone 30N for initial exploration and UTM Zone 30N (WGS84 projection) for final resource definition.

·    Drilling was conducted on nominal grid spacings appropriate for the level of confidence required for resource estimation. In the main mineralised zones (Souwa, Chegue, and Krakara), RC and diamond drilling was performed on approximately 25 m x 25 m to 50 m x 50 m grids. Some areas of denser drilling (for example, grade control drilling) achieved spacing as tight as 10 m x 10 m.

·    Outside the main resource areas, reconnaissance and exploration drilling was more broadly spaced at 80 m x 80 m or larger intervals, appropriate for early-stage resource targeting. Soil sampling grids were generally established on 400 m x 400 m grids, with localised infill to 100 m or 200 m grids as needed. Data spacing was assessed during Mineral Resource estimation and was found sufficient to establish geological and grade continuity for the appropriate classifications (Measured, Indicated, and Inferred). No sample compositing was applied prior to resource estimation; raw assay intervals were used directly in estimation procedures.

·    Drilling programs were designed to target mineralised structures as close to perpendicular as possible to the interpreted dip of mineralisation at each deposit. Most drillholes were oriented towards the southeast or southwest with an inclination of -50° to -60°, depending on the local structural orientation of gold-bearing zones. The mineralisation is generally hosted in north-northeast trending structures dipping moderately to steeply to the east or 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. In areas of uncertainty or more complex structure (fold closures, sheared zones), multiple drill directions were employed to cross-validate mineralisation geometry.

·    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.
