Resource Extension Drilling Results
Ewoyaa Lithium Project, Ghana, West Africa
69 millions à 1.25 % Li2O from 45m returned at Dog-Leg target, outside of current MRE1
Atlantic Lithium Limited (AIM: ALL, ASX: A11, OTCQX: ALLIF, "Atlantic Lithium" or the "Company"), the African-focused lithium exploration and development company targeting to deliver Ghana's first lithium mine, is pleased to announce further broad and high-grade assay results from resource drilling completed at the Company's flagship Ewoyaa Lithium Project ("Ewoyaa" or the "Project") in Ghana, West Africa.
Points forts:
- Further assay results received for 2,514m of extensional resource reverse circulation ("RC") drilling completed at the Dog-Leg target, representing the final results from drilling undertaken in 2023, with a total of 25,898m drilled throughout the year.
- Multiple high-grade and broad extensional drill intersections reported at the new Dog-Leg target outside of the current 35.3Mt @ 1.25% Li2O JORC (2012) compliant Ewoyaa Mineral Resource Estimate1 ("MRE" or the "Resource"), including highlights at a 0.4% Li2O cut-off and a maximum 4m of internal dilution of:
o GRC1024: 69m at 1.25 %Li2O à partir de 45m
o GRC1027: 34m at 1.02 %Li2O à partir de 160m
o GRC1024: 22m at 0.85 %Li2O à partir de 141m
o GRC1030: 16m at 1.08 %Li2O à partir de 111m
o GRC1032: 12m at 1.11 %Li2O à partir de 83m
- Results at Dog-Leg are significant; drilling has intersected shallow dipping, near surface mineralised pegmatite bodies with true thicknesses up to 35m outside of the MRE1, proving potential for significant resource growth.
- The Company is advancing the drilling programme to be undertaken in 2024:
o Plant site sterilisation drilling now completed for a total of 3,177m in 21 holes, with no mineralisation intersected, providing confidence in the proposed plant site location.
o A further 804m of RC drilling and 70m of diamond core drilling recently completed at Dog-Leg, with assay results pending.
o Further resource extension and exploration drilling planned alongside ongoing regional exploration.
- MRE upgrade, for both lithium and feldspar, to incorporate all 2023 and 2024 drilling, targeted for H2 2024.
Commenting on the Company's latest progress, Neil Herbert, Executive Chairman of Atlantic Lithium, said:
"The final assay results from drilling completed in 2023 have again delivered impressive intersections, providing further confidence in the growth potential of the current 35.3Mt @ 1.25% Li2O Resource at the Ewoyaa Lithium Project.
"These results are from the new mineralised area at the Dog-Leg target, located on the northern tip of the Ewoyaa Main deposit, outside of the current MRE, where drilling has returned multiple high-grade and broad near surface extensional intersections, including 69m at 1.25% Li2O from 45m. This follows the intersection of 83m at 1% Li2O from 36m in hole GRC1020 reported at Dog-Leg last month.
"On the back of the encouraging results delivered from drilling completed in 2023 at Dog-Leg, we are excited to have recently completed a further 874m of resource extension drilling at the target as part of our resource growth programme for 2024. We look forward to receiving further drilling results and delivering a MRE upgrade for the Project, targeted for H2 2024. The MRE upgrade will include updates to both the lithium and feldspar and incorporate all of the results received from drilling completed in 2023 and results pending for 2024.
"In addition, we are pleased to have recently completed the plant site sterilisation programme without any surprises, allowing us to continue with our mine site designs and permitting.
"We look forward to updating shareholders on our ongoing progress."
New Drilling Results
Further and final assay results have been received for 2,514m of RC drilling from drilling completed in 2023 at the Ewoyaa Lithium Project. A total of 25,898m of drilling in 157 holes were completed throughout the year; all of which have now been reported. In these latest results, broad high-grade and near surface extensional drilling results have been reported at the new Dog-Leg target. The reported results sit outside of the current MRE1 (reportez-vous Tableau 1, Figure 1, Figure 2, Figure 3, Annexe 1 ainsi que Annexe 2).
Drilling aimed to intersect mineralised pegmatite bodies perpendicular to strike and dip to approximate true width. This is not always achieved due to the variable nature of pegmatites or challenging drill access, with some drill intersections drilled down-dip as apparent widths. Accordingly, estimated true widths are included in the intersections table in Annexe 1.

Remarque: Metal content is based on intercept rather than estimated true width
New drilling at the Dog-Leg target (se référer à l'annonce de 28 Novembre 2023) has delivered broad and high-grade drill intersections, some of which occur near surface and all occurring outside of the current MRE1. Highlights include hole GRC1024: 69m at 1.25% Li2O from 45m and hole GRC1027: 34m at 1.02% Li2O from 160m (refer Figure 1, Figure 2 ainsi que Figure 3).
The results are significant in that an apparent shallow dipping mineralised pegmatite body has been intersected in multiple drill holes with true widths of 20m to 35m which has the potential to add significant near surface resource tonnes.

Figure 3: Cross-section B-B' showing assay results received for holes GRC1030, GRC1031, GRC1032, GRC1033 and GRC1035 at the Dog-Leg target
Additionally, the Company has completed 3,177m of sterilisation drilling in 21 holes at the proposed plant site. No significant mineralisation was observed in drilling, providing confidence in the proposed plant site location.
The Company has also completed a further 804m of RC drilling and 70m of diamond resource extension drilling at the Dog-Leg target with assays pending. The rig has now been demobilised, with drilling planned to recommence in H2 2024.
Meanwhile, regional exploration programmes will continue to advance the exploration project pipeline. The Company will incorporate the results of drilling completed in 2023 and results pending for 2024 into a MRE upgrade for the Project, targeted during H2 2024.
Sample preparation was completed by Intertek Ghana and assay by Intertek Perth, with all reported results passing QA/QC protocols, providing confidence in reported results.

The following extract from the JORC Code 2012 Table 1 is provided for compliance with the Code requirements for the reporting of Exploration Results.
JORC Code Table 1: Section 1 Sampling Techniques and Data
(Les critères de cette section s'appliquent à toutes les sections suivantes).
Critères | Explication du code JORC | Commentaire |
Techniques d'échantillonnage | · Nature et qualité de l'échantillonnage (par exemple, canaux de coupe, puces aléatoires ou outils de mesure standard spécialisés spécifiques de l'industrie adaptés aux minéraux à l'étude, tels que des sondes gamma de fond de trou ou des instruments XRF portables, etc.). Ces exemples ne doivent pas être considérés comme limitant le sens large de l'échantillonnage. · Inclure une référence aux mesures prises pour assurer la représentativité de l'échantillon et l'étalonnage approprié de tout outil ou système de mesure utilisé. · Aspects de la détermination de la minéralisation qui sont importants pour le rapport public. · In cases where 'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1m samples from which 3kg was pulverised to produce a 30g 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 (e.g. submarine nodules) may warrant disclosure of detailed information. | · RC drill holes were routinely sampled at 1m intervals with a nominal 3-6kg sub-sample split off for assay using a rig-mounted cone splitter at 1m intervals. · DD holes were quarter core sampled at 1m intervals or to geological contacts for geochemical analysis. · For assaying, splits from all prospective ore zones (i.e. logged pegmatites +/- interburden) were sent for assay. Outside of these zones, the splits were composited to 4m using a portable riffle splitter. · Holes without pegmatite were not assayed. · Approximately 5% of all samples submitted were standards and coarse blanks. Blanks were typically inserted with the interpreted ore zones after the drilling was completed. · Approximately 2.5% of samples submitted were duplicate samples collected after logging using a riffle splitter and sent to an umpire laboratory. This ensured zones of interest were duplicated and not missed during alternative routine splitting of the primary sample. · Prior to the December 2018 - SGS Tarkwa was used for sample preparation (PRP100) and subsequently forwarded to SGS Johannesburg for analysis; and later SGS Vancouver for analysis (ICP90A). · Post December 2018 to present - Intertek Tarkwa was used for sample preparation (SP02/SP12) and subsequently forwarded to Intertek Perth for analysis (FP6/MS/OES - 21 element combination Na2O2 fusion with combination OES/MS). · ALS Laboratory in Brisbane was used for the Company's initial due diligence work programmes and was selected as the umpire laboratory since Phase 1. ALS conducts ME-ICP89, with a Sodium Peroxide Fusion. Detection limits for lithium are 0.01-10%. Sodium Peroxide fusion is considered a "total" assay technique for lithium. In addition, 22 additional elements assayed with Na2O2 fusion, and combination MS/ICP analysis. |
Critères | Explication du code JORC | Commentaire |
Techniques de forage | · Type de forage (par exemple, carotte, circulation inverse, marteau à trou ouvert, jet d'air rotatif, tarière, Bangka, sonique, etc.) et détails (par exemple, diamètre de la carotte, tube triple ou standard, profondeur des queues de diamant, foret d'échantillonnage facial ou autre type, si le noyau est orienté et si oui, par quelle méthode, etc.). | · Six phases of drilling were undertaken at the Project using RC and DD techniques. All the RC drilling used face sampling hammers. · Phase 1 and 2 programmes used a 5.25 inch hammers while Phase 3 used a 5.75-inch hammer. · All DD holes were completed using PQ and HQ core from surface (85mm and 63.5mm). · All DD holes were drilled in conjunction with a Reflex ACT II tool; to provide an accurate determination of the bottom-of-hole orientation. · All fresh core was orientated to allow for geological, structural and geotechnical logging by a Company geologist. |
Récupération des échantillons de forage | · Méthode d'enregistrement et d'évaluation des récupérations d'échantillons de carottes et de copeaux et évaluation des résultats. · Mesures prises pour maximiser la récupération des échantillons et assurer la représentativité des échantillons. · Existe-t-il une relation entre la récupération et la teneur de l'échantillon et si un biais de l'échantillon peut s'être produit en raison d'une perte/gain préférentiel de matériau fin/grossier. | · A semi-quantitative estimate of sample recovery was completed for the vast majority of drilling. This involved weighing both the bulk samples and splits and calculating theoretical recoveries using assumed densities. Where samples were not weighed, qualitative descriptions of the sample size were recorded. Some sample loss was recorded in the collaring of the RC drill holes. · DD recoveries were measured and recorded. Recoveries in excess of 95.8% have been achieved for the DD drilling programme. Drill sample recovery and quality is adequate for the drilling technique employed. · The DD twin programme has identified a positive grade bias for iron in the RC compared to the DD results. |
Journal | · Si les échantillons de carottes et de copeaux ont été géologiquement et géotechniquement enregistrés à un niveau de détail pour soutenir l'estimation appropriée des ressources minérales, les études minières et les études métallurgiques. · Que l'exploitation forestière soit de nature qualitative ou quantitative. Photographie de noyau (ou costean, canal, etc.). · La longueur totale et le pourcentage des intersections pertinentes enregistrées. | · All drill sample intervals were geologically logged by Company geologists. · Where appropriate, geological logging recorded the abundance of specific minerals, rock types and weathering using a standardised logging system that captured preliminary metallurgical domains. · All logging is qualitative, except for the systematic collection of magnetic susceptibility data which could be considered semi quantitative. · Strip logs have been generated for each drill hole to cross-check geochemical data with geological logging. · A small sample of washed RC drill material was retained in chip trays for future reference and validation of geological logging, and sample reject materials from the laboratory are stored at the Company's field office. · All drill holes have been logged and reviewed by Company technical staff. · The logging is of sufficient detail to support the current reporting of a Mineral Resource. |
Critères | Explication du code JORC | Commentaire |
Techniques de sous-échantillonnage et préparation des échantillons | · Si le noyau, qu'il soit coupé ou scié et si le quart, la moitié ou la totalité du noyau est prélevé. · S'il ne s'agit pas d'une carotte, qu'il s'agisse de rayures, d'un tube échantillonné, d'une fente rotative, etc. et qu'il s'agisse d'un échantillon humide ou sec. · Pour tous les types d'échantillons, la nature, la qualité et l'adéquation de la technique de préparation des échantillons. · Procédures de contrôle de la qualité adoptées pour toutes les étapes de sous-échantillonnage afin de maximiser la représentativité des échantillons. · Mesures prises pour s'assurer que l'échantillonnage est représentatif du matériel collecté in situ, y compris par exemple les résultats de l'échantillonnage en double sur le terrain/de la seconde moitié. · Si les tailles d'échantillon sont appropriées à la granulométrie du matériau échantillonné. | · RC samples were cone split at the drill rig. For interpreted waste zones the 1 or 2m rig splits were later composited using a riffle splitter into 4m composite samples. · DD core was cut with a core saw and selected half core samples dispatched to Nagrom Laboratory in Perth for preliminary metallurgical test work. · The other half of the core, including the bottom-of-hole orientation line, was retained for geological reference. · The remaining DD core was quarter cored for geochemical analysis. · Since December 2018, samples were submitted to Intertek Tarkwa (SP02/SP12) for sample preparation. Samples were weighed, dried and crushed to -2mm in a Boyd crusher with an 800-1,200g rotary split, producing a nominal 1,500g split crushed sample; which was subsequently pulverised in a LM2 ring mill. Samples were pulverised to a nominal 85% passing 75µm. All the preparation equipment was flushed with barren material prior to the commencement of the job. Coarse reject material was kept in the original bag. Lab sizing analysis was undertaken on a nominal 1:25 basis. Final pulverised samples (20g) were airfreighted to Intertek in Perth for assaying. · The vast majority of samples were drilled dry. Moisture content was logged qualitatively. All intersections of the water table were recorded in the database. · Field sample duplicates were taken to evaluate whether samples were representative and understand repeatability, with good repeatability. · Sample sizes and laboratory preparation techniques were appropriate and industry standard. |
Qualité des données de dosage et des tests de laboratoire | · La nature, la qualité et la pertinence des méthodes d'analyse et de laboratoire utilisées et si la technique est considérée comme partielle ou totale. · Pour les outils géophysiques, les spectromètres, les instruments XRF portables, etc., les paramètres utilisés pour déterminer l'analyse, y compris la marque et le modèle de l'instrument, les temps de lecture, les facteurs d'étalonnage appliqués et leur dérivation, etc. · Nature des procédures de contrôle de qualité adoptées (par exemple, standards, blancs, duplicatas, contrôles externes en laboratoire) et si des niveaux acceptables d'exactitude (c'est-à-dire absence de biais) et de précision ont été établis. | · Analysis for lithium and a suite of other elements for Phase 1 drilling was undertaken at SGS Johannesburg / Vancouver by ICP-OES after Sodium Peroxide Fusion. Detection limits for lithium (10ppm - 100,000ppm). Sodium Peroxide fusion is considered a "total" assay technique for lithium. · Review of standards and blanks from the initial submission to Johannesburg identified failures (multiple standards reporting outside control limits). A decision was made to resubmit this batch and all subsequent batches to SGS Vancouver - a laboratory considered to have more experience with this method of analysis and sample type. · Results of analyses for field sample duplicates are consistent with the style of mineralisation and considered to be representative. Internal laboratory QAQC checks are reported by the laboratory, including sizing analysis to monitor preparation and internal laboratory QA/QC. These were reviewed and retained in the company drill hole database. · 155 samples were sent to an umpire laboratory (ALS) and/assayed using equivalent techniques, with results demonstrating good repeatability. · Atlantic Lithium's review of QAQC suggests the SGS Vancouver and Intertek Perth laboratories performed within acceptable limits. · No geophysical methods or hand-held XRF units have been used for determination of grades in the Mineral Resource. |

| · Significant intersections were visually field verified by company geologists and Shaun Searle of Ashmore during the 2019 site visit. · Drill hole data was compiled and digitally captured by Company geologists in the field. Where hand-written information was recorded, all hardcopy records were kept and archived after digitising. · Phase 1 and 2 drilling programmes were captured on paper or locked excel templates and migrated to an MS Access database and then into Datashed (industry standard drill hole database management software). The Phase 3 to 6 programmes were captured using LogChief which has inbuilt data validation protocols. All analytical results were transferred digitally and loaded into the database by a Datashed consultant. · The data was audited, and any discrepancies checked by the Company personnel before being updated in the database. · Twin DD holes were drilled to verify results of the RC drilling programmes. Results indicate that there is iron contamination in the RC drilling process. · Reported drill hole intercepts were compiled by the Chief Geologist. · Adjustments to the original assay data included converting Li ppm to Li2O%. |
Emplacement des points de données | · Précision et qualité des levés utilisés pour localiser les trous de forage (levés au col et en fond de trou), les tranchées, les chantiers miniers et d'autres emplacements utilisés dans l'estimation des ressources minérales. · Spécification du système de grille utilisé. · Qualité et adéquation du contrôle topographique. | · The collar locations were surveyed in WGS84 Zone 30 North using DGPS survey equipment, which is accurate to 0.11mm in both horizontal and vertical directions. All holes were surveyed by qualified surveyors. Once validated, the survey data was uploaded into Datashed. · RC drill holes were routinely down hole surveyed every 6m using a combination of EZ TRAC 1.5 (single shot) and Reflex Gyroscopic tools. · After the tenth drill hole, the survey method was changed to Reflex Gyro survey with 6m down hole data points measured during an end-of-hole survey. · All Phase 2 and 3 drill holes were surveyed initially using the Reflex Gyro tool, but later using the more efficient Reflex SPRINT tool. Phase 4 and 5 drill holes were surveyed using a Reflex SPRINT tool. · LiDAR survey Southern Mapping to produce rectified colour images and a digital terrain model (DTM) 32km2, Aircraft C206 aircraft-mounted LiDAR Riegl Q780 Camera Hasselblad H5Dc with 50mm Fixfocus lens. · Coordinate system: WGS84 UTM30N with accuracy to ±0.04. · The topographic survey and photo mosaic output from the survey is accurate to 20mm. · Locational accuracy at collar and down the drill hole is considered appropriate for resource estimation purposes. |
Espacement et distribution des données | · Espacement des données pour la communication des résultats d'exploration. · Si l'espacement et la distribution des données sont suffisants pour établir le degré de continuité géologique et de teneur approprié pour la ou les procédures d'estimation des ressources minérales et des réserves de minerai et les classifications appliquées. · Si la composition d'échantillons a été appliquée. | · The RC holes were initially drilled on 100m spaced sections and 50m hole spacings orientated at 300° or 330° with dips ranging from -50° to -60°. Planned hole orientations/dips were occasionally adjusted due to pad and/or access constraints. · Hole spacing was reduced to predominantly 40m spaced sections and 40m hole spacings, with infill to 20m by 15m in the upper portions of the Ewoyaa Main deposit. Holes are generally angled perpendicular to interpreted mineralisation orientations at the Project. · Samples were composited to 1m intervals prior to estimation. |

Orientation des données par rapport à la structure géologique | · Si l'orientation de l'échantillonnage permet d'obtenir un échantillonnage impartial des structures possibles et dans quelle mesure cela est connu, compte tenu du type de gisement. · Si la relation entre l'orientation du forage et l'orientation des principales structures minéralisées est considérée comme ayant introduit un biais d'échantillonnage, cela doit être évalué et signalé s'il est important. | · The drill line and drill hole orientation are oriented as close as practicable to perpendicular to the orientation of the general mineralised orientation. · Most of the drilling intersects the mineralisation at close to 90 degrees ensuring intersections are representative of true widths. It is possible that new geological interpretations and/or infill drilling requirements may result in changes to drill orientations on future programmes. · No orientation based sampling bias has been identified in the data. |
Sécurité des échantillons | · Les mesures prises pour assurer la sécurité des échantillons. | · Samples were stored on site prior to road transportation by Company personnel to the SGS preparation laboratory. · With the change of laboratory to Intertek, samples were picked up by the contractor and transported to the sample preparation facility in Tarkwa. |
Audits ou examens | · Les résultats de tout audit ou examen des techniques et des données d'échantillonnage. | · Prior to the drilling programme, a third-party Project review was completed by an independent consultant experienced with the style of mineralisation. · In addition, Shaun Searle of Ashmore reviewed drilling and sampling procedures during the 2019 site visit and found that all procedures and practices conform to industry standards. |

Méthodes d'agrégation de données | · Dans la présentation des résultats d'exploration, les techniques de pondération moyenne, les troncatures de teneur maximale et/ou minimale (par exemple, la coupe de hautes teneurs) et les teneurs de coupure sont généralement importantes et doivent être indiquées. · Lorsque les interceptions agrégées incorporent de courtes longueurs de résultats à haute teneur et de plus longues longueurs de résultats à faible teneur, la procédure utilisée pour une telle agrégation doit être indiquée et quelques exemples typiques de telles agrégations doivent être présentés en détail. · Les hypothèses utilisées pour tout rapport sur les valeurs d'équivalent métal doivent être clairement énoncées. | · Exploration results are not being reported. · Not applicable as a Mineral Resource is being reported. · No metal equivalent values are being reported. |
Relation entre les largeurs de minéralisation et les longueurs d'interception | · Ces relations sont particulièrement importantes dans la communication des résultats d'exploration. · Si la géométrie de la minéralisation par rapport à l'angle du trou de forage est connue, sa nature doit être rapportée. · Si cela n'est pas connu et que seules les longueurs de fond de trou sont indiquées, une déclaration claire doit être faite à cet effet (par exemple « longueur de fond de trou, largeur réelle inconnue »). | · The drill line and drill hole orientation are oriented as close to 90° degrees to the orientation of the anticipated mineralised orientation as practicable. · The majority of the drilling intersects the mineralisation between 60° and 80° degrees. |
Diagrammes | · 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. | · Relevant diagrams have been included within the Mineral Resource report 'Ewoyaa Lithium Project Mineral Resource Estimate' dated 25 March 2023. |
Rapports équilibrés | · Lorsqu'il n'est pas possible de rendre compte de manière exhaustive de tous les résultats d'exploration, il convient de procéder à des comptes rendus représentatifs des teneurs et/ou des largeurs faibles et élevées afin d'éviter une communication trompeuse des résultats d'exploration. | · All hole collars were surveyed WGS84 Zone 30 North grid using a differential GPS. All RC and DD holes were down-hole surveyed with a north-seeking gyroscopic tool. · Exploration results are not being reported. |
Autres données d'exploration importantes | · Les autres données d'exploration, si elles sont significatives et importantes, doivent être rapportées, y compris (mais sans s'y limiter) : les observations géologiques ; résultats des levés géophysiques; résultats des levés géochimiques; échantillons en vrac - taille et méthode de traitement; résultats d'essais métallurgiques; densité apparente, eaux souterraines, caractéristiques géotechniques et rocheuses ; substances potentiellement nocives ou contaminantes. | · Results were estimated from drill hole assay data, with geological logging used to aid interpretation of mineralised contact positions. · Geological observations are included in the report. |
La poursuite des travaux | · La nature et l'ampleur des travaux supplémentaires prévus (par exemple, tests d'extensions latérales ou d'extensions en profondeur ou forage d'extension à grande échelle). · Des diagrammes mettant clairement en évidence les zones d'extensions possibles, y compris les principales interprétations géologiques et les futures zones de forage, à condition que ces informations ne soient pas commercialement sensibles. | · Follow up RC and DD drilling may be undertaken. · Further metallurgical test work may be required as the Project progresses through the study stages. · Drill spacing is currently considered adequate for the current level of interrogation of the Project. |
