Atlantic Lithium Limited (AIM: ALL, OTC: ALLIF, ASX: A11 "Atlantic Lithium" or the "Company"), the funded African-focussed lithium exploration and development company targeting to deliver Ghana's first lithium mine, is pleased to announce final assay results from the resource and exploration drilling programme completed at the Ewoyaa Lithium Project ("Ewoyaa" or the "Project") in Ghana, West Africa.

HIGHLIGHTS:

Ø Final assay results received for a further 10,052m of exploration and infill diamond core ("DD") drilling and reverse circulation ("RC") drilling completed at the Ewoyaa Project, part of the now completed resource evaluation and exploration RC and DD programme.

Ø Newly reported assay results confirm new mineralised pegmatites at the Grasscutter North, Kaampakrom North and Assan targets, outside the currently defined 30.1Mt @ 1.26% Li₂O Ewoyaa JORC (2012) Compliant Mineral Resource Estimate ("MRE" or the "Resource").

Ø Multiple high-grade drill intersections reported at the Kaampakrom North, Grasscutter North, Anokyi and Grasscutter West targets, including highlights of:

o GRC0825: 36m at 1.23% Li₂O from 42m

o GDD0102A: 22.2m at 1.62% Li₂O from 73.3m

o GRC0837: 20m at 1.6% Li₂O from 44m

o GDD0103: 15.1m at 1.24% Li₂O from 55.4m

o GRC0842: 12m at 1.55% Li₂O from 93m

o GRC0839: 13m at 1.35% Li₂O from 99m

o GRC0850: 12m at 1.24% Li₂O from 96m

o GRC0341: 12m at 1.03% Li₂O from 134m

o GRC0844: 7m at 1.69% Li₂O from 162m

o GRC0872: 8m at 1.48% Li₂O from 34m

Ø All assay results now reported for the total approximate 47,000m drilling programme completed.

Ø Resource upgrade targeted for Q1 2023; to inform Definitive Feasibility Study ("DFS") targeted for completion mid-2023.

Ø Recently announced processing plant FEED engineering contract (refer RNS of 13 December 2022) awarded to Primero to optimise the Project's flow sheet, identify long lead items, maximise the Project's long-term profitability, reduce execution risk and ultimately support the advancement of the Project towards becoming a financially and operationally robust lithium-producing mine.

Ø Recently announced Pre-Feasibility Study (refer RNS of 22 September 2022) delivers exceptional financial outcomes for a 2Mtpa operation, producing an average c. 255,000tpa of 6% Li₂O spodumene concentrate ("SC6") over a 12.5-year operation:

o LOM revenues exceeding US$4.84bn, Post-tax NPV₈ of US$1.33bn, IRR of 224% over 12.5 years

o US$125m capital cost with industry-leading payback period of <5 months

o C1 cash operating costs of US$278 per tonne of 6% lithium spodumene concentrate Free on Board ("FOB") Ghana Port, after by-product credits

o Average Life of Mine ("LOM") EBITDA of US$248m per annum

o 18.9Mt at 1.24% Li₂O Maiden Ore Reserve

o Average annualised US$1,359/dry metric tonne SC6 pricing used

Commenting on the Company's latest progress, Lennard Kolff, Interim Chief Executive Officer of Atlantic Lithium, said:

"Drilling continues to deliver high-grade drill intersections outside the current MRE.

"This last batch of results has delivered multiple near-surface drill intersections in new pegmatites defined outside of the resource footprint at the Kaampakrom North and Grasscutter North targets including highlights of 36m at 1.23% Li₂O from 42m and 20m at 1.62% Li₂O from 44m.

"Drilling has also returned high-grade, near-surface results at the Assan target approximately 3km north-east of the northern-most current pit design including highlights of 6m at 1.49% Li₂O from 66m and 6m at 1.44% Li₂O from 45m, demonstrating further potential within the mineralised pegmatite swarm.

"We have now reported all assay results for the approximate 47,000m drilling programme, with a Resource upgrade targeted for Q1 2023 and a DFS targeted for completion mid-2023.

"With the Pre-Feasibility Study delivered, the Mining Licence application submitted, the FEED engineering contract awarded and the funding agreement with our partner Piedmont Lithium in place, we feel the Company is ideally positioned to benefit from the ongoing lithium demand expected over the coming years."

New Drilling Results:

All remaining assay results have been received for an additional 10,052m of RC and DD drilling from the completed drill programme at the Ewoyaa Project. Multiple high-grade drill intersections are reported for exploration drilling results outside of the currently defined Resource at the Kaampakrom North, Grasscutter North and Assan targets as well as infill and metallurgical holes within the current MRE (refer Table 1, Appendix 1 and Appendix 2).

Exploration drilling results fall outside the current 30.1Mt at 1.26% Li₂O Resource on newly defined pegmatites at the Kaampakrom North, Grasscutter North and Assan targets and demonstrates further resource scale potential at the Ewoyaa Project (refer Figure 1, Figure 2 and Figure 3).

Exploration drilling results confirm near-surface mineralisation on newly defined pegmatites within trucking distance of the currently defined mine design. Furthermore, new drilling results demonstrate a further 3km strike extension of prospective lithium pegmatite vein swarms towards the north-east of the current project footprint (refer Figure 1).

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.

'JORC Code 2012 Table 1' Section 1 Sampling Techniques and Data

The following extract from the JORC Code 2012 Table 1 is provided for compliance with the Code requirements for the reporting of Exploration Results.

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.	· 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.
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).	· Five 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 and 5 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.
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.	· 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.
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.	· 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.
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.	· 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 pulps were submitted for analysis by Sodium peroxide fusion (Nickel crucibles) and Hydrochloric acid to dissolve the melt. Analysed by Inductively Coupled Plasma Mass Spectrometry (FP6MS) / Inductively Coupled Plasma Optical (Atomic) Emission Spectrometry (FP6/OE). The analytical suite consisted of Al, B, Ba, Be, Ca, Cs, Fe, K, Li, Mg, Mn, Nb, P, Rb, S, Si, Sn, Sr, Ta and Ti. · 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.
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.	· 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).

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.

· 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.

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).

· Five 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 and 5 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.

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.

· 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.

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.

· 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.

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.

· 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 pulps were submitted for analysis by Sodium peroxide fusion (Nickel crucibles) and Hydrochloric acid to dissolve the melt. Analysed by Inductively Coupled Plasma Mass Spectrometry (FP6MS) / Inductively Coupled Plasma Optical (Atomic) Emission Spectrometry (FP6/OE). The analytical suite consisted of Al, B, Ba, Be, Ca, Cs, Fe, K, Li, Mg, Mn, Nb, P, Rb, S, Si, Sn, Sr, Ta and Ti.

· 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.

· 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.

Appendix - JORC Table 1, Section 2, Reporting of Exploration Results

Criteria	JORC Code explanation	Commentary
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 license to operate in the area.	· Part of the Project is a joint-venture, with the license in the name of the joint-venture party (Barari DV Ghana). · The southern portion of the deposit occurs within a wholly owned local subsidiary Green Metals Resources Ltd. · The deposits are located on two licences Mankessim RL3/55 and Mankessim South PL109 · Mankessim South - (Green Metals Resources Ltd - 100% ALL) licence was renewed for three years and expires on 18^th February 2023. · Mankessim - (Barari DV Ghana Ltd - 90% ALL) was renewed for three years and expires on the 22^nd of March 2024 · The licenses are in good standing with no known impediments.
Exploration done by other parties	· Acknowledgment and appraisal of exploration by other parties.	· Historical trenching and mapping were completed by the Ghana Geological survey during the 1960's. But for some poorly referenced historical maps, none of the technical data from this work was located. Many of the historical trenches were located, cleaned and re-logged. No historical drilling was completed.
Geology	· Deposit type, geological setting and style of mineralisation.	· Pegmatite-hosted lithium deposits are the target for exploration. This style of mineralisation typically forms as dykes and sills intruding or in proximity to granite source rocks. · Surface geology within the Project area typically consists of sequences of staurolite and garnet-bearing pelitic schist and granite with lesser pegmatite and mafic intrusives. Outcrops are typically sparse and confined to ridge tops with colluvium and mottled laterite blanketing much of the undulating terrain making geological mapping challenging. The hills are often separated by broad, sandy drainages.
Drill hole information	· A summary of all information material to the under-standing 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.	· All information has been included in the appendices. No drill hole information has been excluded.
Data aggregation methods	· In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. 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.	· All intersections are reported at a 0.4% Li20 cut-off with maximum 4m of internal pegmatite dilution and no internal waste lithologies whether schist or granite. · No top-cut is applied as lithium pegmatites are a bulk industrial mineral. · No metal equivalent values are being reported.
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 (e.g. 'down hole length, true width not known').	· 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. · Where drilling has drilled down-dip of a known pegmatite, it is reported as such.
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.	· Relevant plans and selected cross-sections have been included within the release.
Balanced Reporting	· 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. · 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.	· 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. · All exploration results are being reported.
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.	· Drill hole intersections were calculated from drill hole assay data, with geological logging used to aid interpretation of mineralised contact positions. · No other exploration data are being reported.
Further work	· The nature and scale of planned further work (e.g. 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.	· Drilling results for a planned infill and extensional drilling programme are being reported. · Follow up RC and DD drilling may be undertaken once all results from the drilling programme are reviewed; either along strike or down-dip of the known pegmatites. · Drill spacing is currently considered adequate for the current level of interrogation of the Project.
