Vancouver, BC – May 25, 2026 – TheNewswire - 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 fromthree major gold anomalous areas by broad-spaced (400m x 400m, 200m x 200m) soil sampling results across the eastern portion of the Zuénoula permit.

Prospect 55 and NE extension: approximately9km strike length

Central Prospect and NE-SW extension: approximately4km strike length

Konezra Prospect and NE extension: approximately 5km strike length

The Fifty-Five Prospect and NE extensiontrends 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 theCentral Prospectarea defined by NE-trending clusters of gold anomalous soil samples, greater than 3.5 km-longand 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, withan 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 theStellar-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 andup 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 potentialemerging at our Zuénoula permit in central-west Côte d’Ivoire”

[]()“The emerging 18kmcombined multiple northeast-trending gold anomalous trends, including a peak soil sample assay result of 1.24 g/t goldlocated near the border of the Zuénoula permit, provides increasing confidence in the general northeast anomalous trend and reinforcing the broader district-scale potentialof 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 areasbybroad-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 anomaloussoil samples (see Figure 2 and Table 1)over greater than 3.5 km-longwhich 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 extensionstretches for approximately9km, and incudes apeak soil result of 1,242 ppb Au (1.24 g/t Au) located near the boundary of the Zuénoula Permit. The anomalous trends remainopen 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 approximately4km.A further potential drill target has been identified from a +3.5 km-long northeast-trending cluster of gold anomaloussoil 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 forapproximately5km 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 imaginginto 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 2most of the very high soil sample results are located on the crestsof 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 drillingduring 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)

JORC Code, 2012 Edition – Table 1

[]()Section 1-Sampling Techniques and Data

Nature and quality of sampling (e.g. cut channels, random chips, or specific specialied industry standard measurement tools appropriate to the minerals under investigation, such as downhole 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 ofmineralisation 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 | -

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 | | Locationof DataPoints | -

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 Spacingand Distribution | -

Data spacing for reporting Exploration Results.

Whethersamplecompositing hasbeenapplied. | -

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 geologicalal 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. | | Sample security | -

The measures taken to ensure sample security. | -

1000g of -2mm sieved fraction of soil samples are collected in plastic bags, assigned individual sample numbers and transported to the secure SEMS compound in Zuénoula
