(via TheNewswire)

Vancouver, BC – September 22, 2026 – TheNewswire – Stellar AfricaGold Inc. (TSXV: SPX, OTC: STLXF) ("Stellar" or the "Company") is pleased to provide an update on the advancement of its fully funded exploration program at the Tichka Est Gold Project, Morocco ( see press release dated August 11, 2026 ).

Highlights

• Following a competitive tender process (AO 01-2026) a contract has been executed with Compagnie Marocaine des Forages Minier ("CMFM"), a Moroccan drilling contractor, for the fully funded Phase II diamond drilling program at the Tichka Est Gold Project, Morocco. Rig mobilization has commenced and drilling is expected to begin in October 2026. The Company will announce the start of drilling.  

• Trenching commenced at the new dyke target area identified by the Company's integrated targeting work ( see news release dated August 11, 2026 ) on September 14, 2026. The trenching program comprises seven mechanical trenches totalling approximately 217 metres, accompanied by detailed structural mapping. Results will be reported once received, validated and interpreted. Five drill holes of the 24-hole Phase II program are provisionally allocated to this area.  

• A contract has been signed with geophysical contractor PROGREM SARL for a high-resolution, closely spaced ("closed-grid") drone magnetic survey over Zones A, B and C: approximately 144 line-kilometres, comprising east–west lines at 50-metre spacing and 500-metre tie lines, flown at a nominal 60-metre terrain clearance. Deliverables include full processing, interpretation and 3D magnetic inversion. Acquisition is scheduled for October 2026. Data will be acquired under strict contractual quality-control acceptance criteria and integrated into drill targeting.  

• The Company's 3D litho-structural model has been refined with the complete, validated Phase I drilling database, finalizing collar positions and orientations for the Phase II 24-hole, ~5,000-metre drill program.  

• Drill platforms, access and water supply are in place . The program remains fully funded.  

Phase II Drilling — Contract Signed, Mobilization Underway

Following the competitive tender launched in August (AO 01-2026), the Company has executed a drilling services contract with Compagnie Marocaine des Forages Minier ("CMFM"). CMFM was selected from a short list of three qualified bidders based on its technical capability, mountain-terrain experience, safety record, schedule and price. The contract includes performance-based requirements, including minimum core recovery in mineralized zones, systematic downhole deviation surveys and oriented core, and the contract preserves the Company's flexibility to re-sequence holes as results are received. Mobilization of the contractor's rig and crews to the High Atlas Tichka Est site is underway; drilling is expected to commence shortly. The first holes of the Phase II program will target the depth and strike extensions of the mineralized diorite sill stack at Zone B, directly beneath drill hole TCK-001 (12 m @ 6.62 g/t Au, including 2 m @ 22.28 g/t Au; see news release dated August 11, 2026 ).

Trenching Underway at the New Dyke Target

Excavation of the first trenches at the new dyke target began on September 14, 2026. The seven-trench program (approximately 217 metres) is designed to test, beneath surface cover, a dyke corridor identified by the convergence of the Company's 2026 satellite remote-sensing study, dyke-population mapping and anomalous rock sampling. Systematic channel sampling and detailed structural mapping are accompanying the excavation. Assay results will be reported once received, validated and interpreted in accordance with NI 43-101 standards. The trenching results will facilitate finalizing the drill plan for the five holes provisionally allocated to this area. At present it in anticipated that this new dyke target will be drilled in Q4 2026 following the drill holes planned for Zone B.

CEO, Mr JF. Lalonde, commented:

“This drilling campaign represents an important milestone in Stellar AfricaGold’s exploration of Tichka Est. I am very proud of the team's work ethics. The drilling contractor was selected after a competitive process, and the past six months of disciplined work led to a sound program identifying the proposed new drill targets.

I am keen to begin this fall season’s major exploration program and look forward to receiving the assay results—first from the trenching campaign that is currently underway on the newly identified mineralized dyke zone, and subsquently from the drilling campaign, both of which could open entirely new target areas in Tichka Est.”

Geophysics — Detailed Survey Contracted; Regional Interpretation Completed

A contract has been signed with geophysical contractor PROGREM SARL for a high-resolution, closely spaced ("closed-grid") drone magnetic survey over Zones A, B and C: approximately 144 line-kilometres, comprising east–west lines at 50-metre spacing and 500-metre tie lines, flown at a nominal 60-metre terrain clearance. Deliverables include full processing, interpretation and 3D magnetic inversion.

The closed-grid drone magnetic survey will map the geometry of the diorite sills and dykes that host gold mineralization, resolve late-fault offsets, and test the geophysical expression of the hydrothermal system interpreted from the Company's 2026 lithogeochemical survey. The survey will be flown with a Geometrics MagArrow magnetometer towed beneath a DJI Matrice 350 RTK platform, with an Overhauser base station for diurnal correction, terrain-following flight plans built on a high-resolution digital terrain model, and a daily repeat-line quality control protocol; acquisition, processing and 3D magnetic inversion are governed by contractual quality-control acceptance criteria. Acquisition is scheduled for October 2026, subject to weather windows at site elevations of up to approximately 2,500 metres.

About the Tichka Est Gold Project

The Tichka Est Gold Project comprises five research permits and one exploitation licence covering 82 km² in the High Atlas region of Morocco, approximately 90 km south of Marrakech. Under an earn-in agreement with Morocco's Office National des Hydrocarbures et des Mines (ONHYM), Stellar can earn an 85% interest in the project by incurring US$2.39 million in exploration expenditures over three years. Gold mineralization is currently recognized in three zones: Zone A, Zone B representing the most advanced area following recent drilling, and Zone C. Much of the 82 km² project area remains unexplored or only superficially explored.
