STELLAR AFRICAGOLD - 10,000M AUGER DRILLING PLANNED TO TEST
7 POTENTIAL DRILL TARGET AREAS AT THE ZUÉNOULA PERMIT, CÔTE D’IVOIRE
Vancouver, BC – June 23, 2026 Stellar AfricaGold Inc. (“Stellar” or the “Company”) (TSXV: SPX, TGAT:
6YP and FSX: 6YP) is pleased to announce a 10,000 meter auger drill program at the Stellar-MetalsGrove
Joint Venture Zuénoula Gold Project, Cote d’Ivoire.
Highlights
• Joint venture operator MetalsGrove Mining Ltd. (“MetalsGrove”) has consolidated the
exploration targets at the Zuénoula Permit into four principal prospects - Fifty-Five, Central, South East
and South West Prospects following ongoing technical review and field verification of multiple gold
anomalies.
• A two -rig, two -stage 10,000-meter auger drilling program is planned to test gold
anomalous clusters at the Fifty-Five, Central and South East Prospects, with mobilisation and
commencement targeted for end June.
• Recent soil geochemistry interpretation has defined a total of 7 Potential Drill Targets
within the consolidated 4 prospects on the permit. These targets will be progressively refined
through ongoing infill soil sampling and auger drilling before drilled by Aircore/Reverse Circulation
(AC/RC) or diamond drilling (DD) from late 2026.
• Infill soil sampling programs continue across all four prospects at varying grid spacings,
with results continuing to enhance target definition and prioritisation for drill testing.

Stellar Management Commentary
Stellar President and CEO J. François Lalonde commented:
"Following extensive soil sampling and target refinement, the joint venture exploration team has
consolidated the Zuénoula Permit into four principal prospect areas and are preparing to commence a
10,000-meter auger drilling program across the 7 defined potential drill targets. The program is
designed to test the bedrock potential beneath surface gold anomalies and represents a critical step
towards AC, RC and diamond drilling later this year.
The definition of seven potential drill targets marks an important milestone in the systematic exploration
approach and highlights the growing scale and prospectivity of the Zuénoula Gold Project . Several
targets exhibit kilometre-scale strike lengths and remain open to further refinement through ongoing
infill soil sampling. With more than 1,700 soil samples currently awaiting assay results, there is
significant potential to further expand these targets and discover more targets across the permit.
We look forward to updating shareholders as auger drilling commences and additional soil sampling
assay results continue to strengthen the discovery potential at Zuénoula."
MULTIPLE NORTHEAST-TRENDING GOLD ANOMALOUS TRENDS IDENTIFIED
Stellar is pleased to announce the planned commencement of a two-rig, two-stage, 10,000 meter auger
drilling program at its Zuénoula Permit in Côte d’Ivoire to test the area’s seven potential drill targets
defined from multiple gold anomalies identified through the Company’s systematic soil geochemistry
programs.
The joint venture operator has consolidated the exploration targets at the Zuénoula Permit into four
principal prospects following ongoing technical review and field verification of multiple gold anomalies
identified from completed various surface soil sampling programs to date (Figure 1). The Fifty -Five
Prospect now incorporates the original Fi fty-Five Prospect and its northeastern extension, while the
South East Prospect combines the former Konezra Prospect with the South East Prospect. The Central
Prospect and South West Prospect remain unchanged from previous reporting. This refinement
provides a clearer framework for exploration targeting and reflects the Company's growing
understanding of the distribution and continuity of gold anomalism across the project area.
Figure 1. Zuénoula Soil Sampling Progress Across the Four Consolidated Exploration Prospects
A two -rig, two -stage, 10,000 m auger drilling program within the Fifty -Five, Central and South East
Prospects has been designed (Figure 2) to test the most significant gold anomalous clusters identified.
Stage 1 will comprise approximately 5,000m of drilling on a nominal 400m × 50m drill pattern, followed
by Stage 2 infill drilling on a 250m × 25m spacing, subject to the results obtained from the initial phase.
Auger drilling is planned to an average depth of approximately five metres to test the mineralisation
potential from the upper saprolite horizon. Results from ongoing soil infill programs across all three
auger target areas will be incorporated into final drill planning to further refine and optimise drill line
locations prior to commencement. The two-rig mobilisation and commencement date is scheduled for
end June 2026.
Interpretation of the current soil geochemistry dataset (Figure 1 & Table 1) has increased the definition
of potential drill targets to 7 (Figure 2), each exhibiting kilometre-scale prospective strike length (Figure
3 and 4). These targets will continue to be refined through ongoing infill soil sampling and auger drilling
programs, with the objective of defining coherent bedrock-related mineralisation suitable for follow-up
AC/RC or DD from late 2026.
Infill soil sampling continues at varying grid spacings across all four prospects at the Zuénoula Permit.
To date, assay results have been received for 1,617 soil samples , while a further 1,755 samples are
awaiting laboratory analysis. An additional 306 samples are scheduled for collection.

Section 1- Sampling T echniques and Data
Criteria JORC Code Explanation Commentary
Sampling
Techniques
• Nature and quality of sampling (e.g.
cut channels, random chips, or
specific specialized 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
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
(e.g. submarine nodules) may warrant
disclosure of detailed information.
No drilling has been undertaken on Zuénoula
PR-750
All soil samples collected on Zuénoula PR -
750 have been analysed for gold by fire assay
at Bureau Veritas laboratory in Abidjan, Côte
d’Ivoire.
SOIL SAMPLING STAGES
• Stage 1: Initial, permit -wide, broad -
spaced soil sampling on 1000m x 1000m
grid
• Stage 2: Gold anomalous clusters and
trends defined by multiple anomalous soil
samples (+20ppb Au) are then infilled with
soil samples collected on 400m x 400m
grid
• Stage 3: Coherent gold soil anomalies are
then infilled with soil samples collected on
200m x 200m grid
• Stage 4: Higher density 200m x 50m soil
sampling to sharpen definition of gold soil
anomalies
• Stage 5: Augering and trenching of
coherent gold soil anomalies
• Stage 6: Drill testing of gold soil and auger
anomalies.
SOIL SAMPLING PROCEDURES
• MGA has contracted the experienced
consulting group SEMS Exploration
Services (SEMS) to conduct all soil
sampling
• Up to four sampling crews may be active at
any one time
• The MGA Exploration Manager was onsite
at the start of the field program to instruct
the sampling crew on the Standard
Sampling Procedure required by MGA
• MGA provided SEMS Exploration Services
with an Excel table listing the designated
sample point locations using WGS-84 UTM
zone 29N coordinates
• Each soil sample is collected from within
20 metres of the designated sample point,
with the actual sample point then
recorded
• At each sample point: 1) the organic rich
soil is brushed away, 2) a 40cm deep hole
dug and the sample collected by taking a
channel-cut along the bottom 20cm of the
hole, 3) 1000g of the minus 2mm sieved
fraction of each sample is collected from
the sample point, 4) gold is determined by
fire assay (LDL 2ppb)
• Duplicate samples are collected every
20th sample, certified reference material
(CRM) inserted every 20th sample, and
blanks inserted every 20th sample.
• Samples are stored at the secure SEMS
field compound in Zuénoula prior to
transport to Bureau Veritas in Abidjan of
gold 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).
• No drilling has been undertaken.
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.
• No drilling has been undertaken.
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.
• No drilling has been undertaken
• Soil samples are comprehensively logged
for a range of parameters including colour,
soil horizon, sample weight, slope,
dominant grain size (clay, silt, sand),
general topography, residual or
transported, proximity to artisanal
workings, other ground disturbances such
as field plowing, and general land use
(grassland, plantation, crop, etc.).
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.
• No drilling has been undertaken
• No sub -sampling of the 1000g soil
samples is undertaken prior to the sample
arriving at Bureau Veritas laboratory
• At Bureau Veritas, the entire 1000g sample
is pulped prior to the laboratory taking a
50g split for lead collection fire assay
determination of gold concentration.
• 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.
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, calibration
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.
• Bureau Veritas is an internationally
accredited assay laboratory located in
Abidjan, Cote d’Ivoire.
• Assay results for all samples presented in
the announcement were determined by fire
assay (Lab Code: FE450, LDL 2ppb), which
is a total gold extraction method for
analysis.
• The lower detection limit (LDL) of 2ppb is
considered appropriate for greenfields,
early stage, exploration soil sampling
• Fire assay gold is considered one of the
most reliable assay techniques for gold
analyses.
Verification of
Sampling and
Assaying
• The verification of significant
intersections by either independent
or alternative company personnel.
• The use of twinned holes.
• Documentation of primary data, data
entry procedures, data verification,
data storage (physical and electronic)
protocols.
• Discuss any adjustments to assay
data.
FIRE ASSAY ANALYSIS
• All samples have been analysed for gold
by fire assay at Bureau Veritas laboratory
in Abidjan, Cote d’Ivoire
• The 1000g -2mm sample collected in the
field is analysed for gold by fire assay (Lab
Code: FE450, LDL 2ppb)
• At the laboratory, the 1000g -2mm
sample is dried and pulverised to 85%
passing 75 microns.
• This sample pulp is then mixed with a
combination of chemical reagents, which
when heated to high temperatures
results in the formation of a lead button
and slag. The lead button that contains
the precious metals (including gold) is
cupelled at high temperature. The lead is
adsorbed by the cupel leaving behind a
bead that contains the precious metals.
• The bead is acid digested and analysed
by AAS, with a lower detection limit of
2ppb Au
