Vancouver, BC – July 15, 2026 – TheNewswire -Stellar AfricaGold Inc. (“Stellar” or the “Company”) (TSXV: SPX, TGAT: 6YP and FSX: 6YP) is pleased to announce that a 10,000-meter auger drill program is now underway at the Stellar-MetalsGrove Joint Venture Zuénoula Gold Project, Cote d’Ivoire.

[]()Highlights

-

Ongoing technical review and interpretation of recent infill soil sampling results have refined the exploration focus at the Zuénoula Permit to the area of six drill targetswithin three principal prospects: Fifty-Five, Central and South East.

-

These targets will be progressively refined through additional infill soil sampling and auger drilling before advancing to Aircore (AC), Reverse Circulation (RC) and Diamond Drilling (DD) programs anticipated to begin in late 2026

-

New 200m × 50m infill soil sampling results from the Fifty-Five Prospecthave extendedDrill Target T1 to a strike length of approximately 3.3km. The program also returned a new peak soil assay of 1,324ppb Au (1.324g/t Au), further supporting the high prospectivity of the target area.

-

The 10,000-metre auger drilling program has commencedand will test the highest-priority gold anomalous cluster areas encompassing Drill Targets T1 and T3–T5within the Fifty-Fiveand Central Prospects

-

The Auger drillingprogram has been designed to drill an average depth of approximately 5 metres, targeting the upper saprolite horizonto evaluate the bedrock potential beneath the surface soil gold anomalies.

-

A 200m X 50minfill soil sampling program is underway across DrillTarget T6 within the South East Prospect, and a similar program is scheduled over Drill Target T2in the northeastern extension of the Fifty-Five Prospect. These programs are designed to further refine drill target geometry and prioritise targets for follow-up auger drilling.

-

Assay results have been received for 3,372 soil samples, with a further 343samples pending assay. In parallel, 601additional soil samples are being collected, while auger drilling comprising 503 holes at the Fifty-Five Prospect and472 holes at the Central Prospectis underway.

[]()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 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:

"The commencement of auger drilling represents an important milestonein the Joint Venture’s systematic exploration strategy at the Zuénoula Permit. Over the past 6 months, the project has been progressively advanced from regional reconnaissance through multiple phases of soil geochemistry, enabling the exploration team to refine its focus to three principal prospects and six drill targets. This disciplined approach is now delivering tangible drill-ready targets for the first phase of subsurface testing.

The continued expansion of drill target T1 to approximately 3.3 kilometresand the identification of a new peak soil assay of 1.324 g/t goldfrom the prospect area reinforces our confidence in the scale and prospectivity of the Zuénoula gold system. These results demonstrate that ongoing infill soil sampling continues to enhance our understanding of the Zuénoula project and improve the quality of drill targeting.

Importantly, the auger drilling program is expected to provide the first direct assessment of the bedrock potential beneath these extensive surface gold anomalies. Together with additional infill soil sampling planned over the remaining target areas, the results will be used to prioritise follow-up Aircore, Reverse Circulation and diamond drilling later this year. We believe the Zuénoula Permit continues to demonstrate significant potential for gold discoveriesas our exploration progresses."

10,000-METER AUGER DRILLING PROGRAM COMMENCED; SIX DRILL TARGET AREAS TO BE TESTED

Stellar is pleased to announce that a 10,000m auger drilling program has commenced at its Zuénoula Permitin Côte d’Ivoire to test six drill target areasdefined from multiple gold anomalies identified through the Company’s systematic soil geochemistry programs.

Ongoing interpretation of recently completed infill soil sample results (Table 1) has further enhanced the Joint Venture’s understanding of the Zuénoula Permit, enabling exploration activities to be focused on three principal prospects: Fifty-Five, Central and South East(Figure 1),where increased confidence in the continuity and distribution of gold anomalism has led to the definition of six drill targets, which will be systematically evaluated through the current auger drilling program before advancing to Aircore (AC), Reverse Circulation (RC) and Diamond Drilling (DD) from late 2026.

Auger Drilling Program

The planned 10,000-meter auger drilling program has commenced following successful meetings with local authorities, including mines department and various community representatives. The initial program will focus on the highest-priority gold anomalous clusters identified from systematic soil geochemistry around the areas of Drill Targets T1 and T3–T5 within the Fifty-Five and Central Prospects, providing the first direct assessment of potential bedrock-related gold mineralisation beneath the surface geochemical anomalies. Results from this program will be used to refine subsequent drill targeting and guide follow-up exploration.

The auger drilling program has been designed to an average depth of approximately five metres, targeting the upper saprolite horizon where residual gold geochemical signatures are expected to be best preserved. Drilling through the complete weathering profile will provide important geological and regolith information while enabling evaluation of the relationship between surface soil anomalies and the potential underlying saprolite-hosted mineralisation.

A selective sampling strategy has been adopted to maximise geological information while maintaining analytical efficiency. Holes located within priority drill target areas will be sampled as continuous 2m composite intervals throughout the entire hole, together with an additional bottom-of-hole (BOH) sample collected from the upper saprolite horizon. Outside the priority target areas, only the BOH sample will be collected. This approach is expected to provide a better understanding of vertical gold distribution within the weathering profile and improve interpretation of the relationship between surface geochemical anomalies and potential bedrock mineralisation.

Continuing soil sampling

Infill soil sampling at 200m × 50m spacing will continue to support target refinement across the Zuénoula Permit. The current program is focused on Drill Target T6 within the South East Prospect, with a further campaign planned over Drill Target T2 in the northeastern extension of the Fifty-Five Prospect. These programs are designed to improve anomaly definition, refine drill target geometry and assist in prioritising targets for future auger and follow-up AC, RC, or DD drilling.

| Criteria | JORCCodeExplanation | Commentary | | Sampling Techniques | -

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.

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. | 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 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 | -
