Multiple Broad and High-Grade
Drill Intersections
Resource
Extension Drilling Results
Ewoyaa Lithium
Project, Ghana, West Africa
83m at 1%
Li2O from 36m Returned at Dog-Leg Target
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 the resource drilling completed
during 2023 at the Company's flagship Ewoyaa Lithium Project
("Ewoyaa" or the "Project") in Ghana, West Africa.
Highlights:
-
Further assay results received for 7,220m of extensional
resource reverse circulation ("RC") drilling completed at Ewoyaa as
part of the ongoing 2023/2024 drilling programme.
-
Multiple high-grade and broad extensional drill intersections
reported at the new Dog-Leg target, Okwesi, Anokyi and Ewoyaa-South
2 deposits outside of the current 35.3Mt @ 1.25% Li2O
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 GRC1020: 83m at 1%
Li20 from 36m
o GRC1017: 47m at 1.05%
Li2O from 87m
o GRC0996: 24m at 1.21%
Li2O from 29m
o GRC0994: 11m at 1.9%
Li2O from 105m
o GRC1023: 24m at 0.81%
Li2O from 159m
o GRC1020: 21m at 0.87%
Li2O from 139m
o GRC0989: 12m at 1.49%
Li2O from 108m
o GRC0983: 12m at 1.34%
Li2O from 38m
o GRC1000: 9m at 1.68%
Li2O from 22m
-
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 MRE, proving potential
for significant resource growth.
-
Drilling to recommence shortly; prioritisation of the
recently added 3,000m plant site sterilisation programme in support
of mine site commissioning, ahead of completion of the remaining
26,500m resource growth and infill programme commenced in
2023.
Commenting on the Company's latest progress, Neil Herbert,
Executive Chairman of Atlantic Lithium,
said:
"We
are pleased to deliver further impressive assay results from
drilling completed in 2023, part of the ongoing programme. These
latest results from the new Dog-Leg target, Okwesi, Anokyi and
Ewoyaa South-2 deposits have returned multiple high-grade and broad
extensional intersections, including 83m at 1% Li2O from
36m and 47m at 1.05% Li2O from 87m at the new Dog-Leg
target.
"All reported drilling results fall outside of the current
MRE; pertinent in that they occur both within a new mineralised
area at the Dog-Leg target and near surface at both the Dog-Leg
target and Ewoyaa-South 2 deposit strike
extension.
"We
are excited to re-commence drilling for the 2024 season with an
initial focus on 3,000m of sterilisation drilling at the proposed
plant site and then the remaining meterage of the ongoing 26,500m
resource drilling programme targeting Resource growth and
conversion.
"We
look forward to updating shareholders on our ongoing progress,
including as remaining assay results for drilling completed during
2023 become available."
New Drilling Results
Further assay results have been received for
7,720m of RC drilling from the ongoing 2023 drill programme at the
Ewoyaa Lithium Project. Broad high-grade extensional drilling
results have been reported at the new Dog-Leg target and Okwesi,
Anokyi and Ewoyaa South-2 deposits. The reported results sit
outside of the current MRE1 (refer Table
1, Table 2,
Appendix 1 and Appendix 2).
Further extensional drilling results have
defined new mineralisation at the Dog-Leg target and extended
mineralisation at depth outside of the current MRE1 at
the Okwesi, Anokyi and Ewoyaa-South 2 deposits (refer Figure
1, Figure 2, Figure
3 and Figure
4) respectively, including highlight intersections at
a 0.4% Li2O cut-off and a maximum 4m of internal
dilution shown in Table
1.
Drilling aims 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
Appendix
1.

0.4% Li2O cut-off and maximum of 4m of
internal dilution

Broad and high-grade drill intersections are
reported for resource drilling at the new Dog-Leg target in
addition to extensional resource drilling at the Okwesi, Anokyi and
Ewoyaa South-2 deposits.
New drilling at the Dog-Leg target
(refer announcement of
28 November 2023)
has delivered broad and high-grade drill intersection, some of
which occur near surface and all occurring outside of the current
MRE1. Highlights include hole GRC1020: 83m at 1%
Li20 from 36m and hole GRC1017: 47m at 1.05%
Li2O from 87m (refer Figure 1, Figure 2 and 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.

Mineralisation has been extended outside of the
current MRE1 along strike for a further 120m and near
surface at the Ewoyaa-South 2 deposit including highlights in holes
GRC0996: 24m at 1.21% Li2O from 29m, GRC0983: 12m at
1.34% Li2O from 38m and GRC1000: 9m at 1.68%
Li2O from 22m providing potential for further resource
growth near surface (refer
Figure 1 and Figure 4).

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
(Criteria in this section apply to all
succeeding sections).
|
Sampling
techniques
|
·
Nature and quality of sampling (e.g. 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 (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.
|
|
Drilling
techniques
|
·
Drill type (e.g. core, reverse circulation, open-hole hammer,
rotary air blast, auger, Bangka, sonic, etc.) and details (e.g.
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.).
|
·
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.
|
|
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.

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 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 (e.g. standards,
blanks, duplicates, external laboratory checks) and whether
acceptable levels of accuracy (i.e. 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). 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.

·
Documentation of primary data, data entry procedures, data
verification, data storage (physical and electronic)
protocols.
·
Discuss any adjustment to assay data.
|
·
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%.

·
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.
|
·
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.

·
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.
|
|
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.
|
·
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 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.
|
·
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.
|
|
Sample
security
|
·
The measures taken to ensure sample security.
|
·
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 or
reviews
|
·
The results of any audits or reviews of sampling techniques
and data.
|
·
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.

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.

Drillhole
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
·
downhole 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.
|
·
No exploration results are being reported.
·
All information was included in the appendices (of the
Mineral Resource report). No drill hole information were excluded
(from the Mineral Resource report).

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.
|
·
Exploration results are not being reported.
·
Not applicable as a Mineral Resource is being
reported.
·
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 downhole lengths are
reported, there should be a clear statement to this effect (e.g.
'downhole 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.
|
|
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 diagrams have been included within the Mineral
Resource report 'Ewoyaa Lithium Project Mineral Resource Estimate'
dated 25 March 2023.
|
|
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.
|
·
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.
|
|
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.
|
·
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.
|
|
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.
|
·
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.
