Vancouver, BC – May 25, 2026 Stellar AfricaGold Inc. (“Stellar” or the “Company”) (TSXV: SPX, TGAT:
6YP and FSX: 6YP) provides the following update on the exploration progress at the Stellar-MetalsGrove
Joint Venture Zuénoula Gold Project, Cote d’Ivoire.
Highlights
• Multiple gold anomalous trends with a combined strike length of approximately 18km have
been identified from three major gold anomalous areas by broad-spaced (400m x 400m, 200m x 200m)
soil sampling results across the eastern portion of the Zuénoula permit.
o Prospect 55 and NE extension: approximately 9km strike length
o Central Prospect and NE-SW extension: approximately 4km strike length
o Konezra Prospect and NE extension: approximately 5km strike length
• The Fifty-Five Prospect and NE extension trends strike northeast with a peak soil value of 1,242
ppb Au (1.24 g/t Au) returned from the permit boundary.
• In addition to the previously announced potential drill target in Fifty -Five Prospect area (see
News Release May 13, 2026 ), a further potential drill target is defined in the Central Prospect area
defined by NE-trending clusters of gold anomalous soil samples, greater than 3.5 km -long and open
to the northeast with assays pending.
• The NE-orientation of multiple gold anomalous trends is parallel to major regional structures,
increasing confidence in the project’s gold discovery potential.
• Three sampling crews are currently working to complete multiple expansive 200m x 50m infill
soil sampling programs, with an additional 1,100 soil samples scheduled on Zuénoula Permit.
• Auger drilling program considered feasible during the coming wet season (June – September)
providing the potential for continued news flow during the wet season.
• Definition of multiple potential drill targets by October 2026 is considered highly probable,
with drilling expected to commence at the start of the dry season.
• Assay results have been received for 1,617 soil samples , with assays for a further 388 soil
samples pending
About the Stellar-MetalsGrove Joint Venture Zuénoula Gold Project, Cote d’Ivoire.
The Stellar-MetalsGrove Zuénoula Gold Project is a joint venture exploration project between Stellar’s
Ivorian subsidiary Aucrest SARL (“Aucrest”) and MetalsGrove Mining Ltd. ’s Ivorian subsidiary
MetalsGrove CDI Pty Ltd (MetalsGrove) to advance Stellar’s 395.78 square kilometer early -stage
exploration permit called Zuénoula in Côte d’Ivoire (see Figure 2 below). Pursuant to the joint venture
agreement MetalsGrove, the project operator, may earn up to a 50% interest in the Zuénoula Gold
Project by incurring US$3,000,000 in exploration expenditures and up to an 80% interest in the
Zuénoula Gold Project by incurring a total of US$6,000,000 in exploration expenditures. ( For further
details of the Stellar-MetalsGrove Joint Venture Agreement see Stellar news release December 9, 2025.)
Stellar Management Commentary
Stellar President and CEO J. François Lalonde commented:
“These latest soil sampling results continue to highlight the strong gold discovery potential emerging
at our Zuénoula permit in central-west Côte d’Ivoire”
“The emerging 18km combined multiple northeast-trending gold anomalous trends , including a peak soil
sample assay result of 1.24 g/t gold located near the border of the Zuénoula permit, provides increasing
confidence in the general northeast anomalous trend and reinforcing the broader district-scale
potential of the Zuénoula permit .”
“With three field crews currently completing expansive infill soil sampling programs and further assay
results pending, we believe the Stellar -MetalsGrove Joint Venture Zuénoula Gold Project is rapidly
advancing towards the definition of multiple potential drill targets ahead of planned drilling activities
later this year.”
MULTIPLE NORTHEAST-TRENDING GOLD ANOMALOUS TRENDS IDENTIFIED
Stellar is pleased to announce that 18km combined multiple northeast -trending gold anomalous
trends (Figure 1) have been identified from three major gold anomalous areas by broad-spaced soil
sampling programs completed on 400m x 400m and 200m x 200m spacing across the eastern portion
of the Zuénoula Permit in Côte d’Ivoire.
At the Central Prospect, a further potential drill target has been identified from a northeast-trending
cluster of gold anomalous soil samples (see Figure 2 and Table 1) over greater than 3.5 km-long which
remains open to the northeast . The NE orientation of the soil anomalism is interpreted to reflect
favourable structural controls associated with major regional fault systems in this highly prospective
greenstone belt. Importantly, the general anomalous trends remain open to the northeast reinforcing
the broader district-scale exploration potential of the Zuénoula Permit.
• The Fifty-Five Prospect and NE extension stretches for approximately 9km, and incudes a peak
soil result of 1,242 ppb Au (1.24 g/t Au) located near the boundary of the Zuénoula Permit. The
anomalous trends remain open to the northeast, reinforcing the broader district -scale
exploration potential across MetalsGrove’s strategic landholding position.
• The Central Prospect and NE-SW extension stretch for approximately 4km. A further potential
drill target has been identified from a +3.5 km -long northeast -trending cluster of gold
anomalous soil samples (Figure 2) which remains open to the northeast. The NE- orientation of
the soil anomalism is interpreted to reflect favourable structural controls associated with major
regional fault systems in this highly prospective greenstone belt.
• The Konezra Prospect and NE extension stretches for approximately 5km from current sample
spacing of 400m x 400m and is pending further infill sampling.
The Joint Venture has integrated completed high-resolution LiDAR and orthophoto survey data
imaging into the exploration interpretation process to assist with topographical analysis, drainage
interpretation, geochemical dispersion assessment and planning of future infill soil sampling and auger
drilling traverses. It is noteworthy that on Figure 2 most of the very high soil sample results are located
on the crests of the topography.
Three field crews are currently advancing multiple expansive 200m x 50m infill soil sampling programs
designed to tighten target definition ahead of drilling, with approximately 1,500 additional soil samples
scheduled. Assay results have now been received for 1,617 soil samples, with a further 388 samples
pending laboratory analysis.
MetalsGrove, the Zuénoula Joint Venture Operator, considers that auger drilling during the upcoming
wet season (June to September) to be feasible following positive site access assessment by the JV
Exploration Manager. Auger drilling is expected to provide important geological and geochemical
information beneath transported cover and assist in refining drill targeting ahead of planned RC and/or
diamond drilling programs during the dry season.
Next Phases of Work
The Joint Venture has planned the following next phases of exploration programs to advance the
identification of additional gold exploration targets:
• Central Prospect: Infill soil sampling on 200m x 50m grid (500 samples)
• Fifty-Five Prospect: Infill soil sampling on 200m x 50m grid (630 samples)

Sampling
T echniques
• 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
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.
problems. Unusual commodities or
mineralisation types (e.g. submarine
nodules) may warrant disclosure of
detailed information.
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 sampl e
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
T echniques

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.

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.
• 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.
• No drilling has been undertaken
• No sub-sampling of the 1000g soil samples is
undertaken prior to the sample arriving at
Bureau Veritas laboratory

pulped prior to the laboratory taking a 50g
split for lead collection fire assay
determination of gold concentration.
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,

protocols.
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
• Discuss any adjustments to assay data. 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
Location of
Data Points
• Accuracy and quality of surveys used to
locate drillholes (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.
• A handheld GPS is used to locate the soil data
positions, with a +/ -5m vertical and
horizontal accuracy
• Sample locations (UTM WGS -84 zone 29N)
and sample descriptions are noted on a
standard form in the field and entered on a
computer.
• GPS measurements of sample positions are
sufficiently accurate for exploration targeting
gold systems.
Data Spacing
and
Distribution
• Data spacing for reporting 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.
• An 1,000m x 1,000m offset grid pattern has
been adopted for the entire permit area,
excluding areas of irrigated sugar cane and
villages.
• Broad-spaced soil sampling (1000m by
1000m) and low level gold fire assay analysis
(LDL 2ppb) is considered an effective
technique for identifying and delimiting gold
anomalous clusters and trends, which are
then followed up with higher density
sampling at 400m × 400m, 200m x 200m,
and in some areas 200m x 50m, as the next
phases of sampling ahead of trenching,
augering, and drill testing of coherent gold
soil anomalies.
Orientation
of data in
relation to
geological al
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 sample location configuration has been
deliberately planned to avoid directional
bias.
