Stellar AfricaGold - 10,000M Auger Drilling Planned to Test 7 Potential Drill Target Areas at the Zuénoula Permit, Côte D’Ivoire

Exploration Programs

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.

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:

"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 Fifty-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.
