Stellar AfricaGold Identifies Priority Gold Exploration Targets at Zuénoula Project

Vancouver, BC — May 13, 2026 — Leads & Copy — Stellar AfricaGold Inc. (TSXV: SPX) has announced exploration progress at the Stellar-MetalsGrove Joint Venture Zuénoula Gold Project in Cote d’Ivoire, highlighting the selection of priority exploration targets.

Two gold anomalous trends have been identified within Zuénoula’s Fifty-Five Prospect area. These parallel, northeast-trending clusters of gold anomalous soil samples exceed 20 parts per billion (ppb) of gold, peaking at 583 ppb. These trends, stretching over 2.5 kilometers, have been selected as Priority Exploration Targets.

Existing soil sampling, conducted at broad intervals of 200 meters by 200 meters, will be infilled to a tighter grid of 200 meters by 50 meters. This densification aims to refine the definition of the two 1.5 square kilometer exploration targets in anticipation of auger drilling.

The northeast orientation of the gold anomalous trends is believed to mirror the primary fault architecture within this prospective greenstone belt.

Sampling of termite mounds and mesothermal quartz vein float, located near sites with soil samples exceeding 100 ppb gold, has been completed. The samples are currently at the Bureau Veritas laboratory in Abidjan for assay.

Topographical mapping, utilizing high-resolution LiDAR-orthophoto survey data, has been completed. This mapping supports the interpretation of soil geochemistry and the planning of infill soil sample and auger drill programs.

An auger drilling program is considered feasible during the upcoming wet season, which spans from June to September.

Assay results have been received for 1,000 soil samples, with an additional 617 soil samples currently at the Bureau Veritas laboratory in Abidjan.

The Zuénoula Gold Project operates as a joint venture exploration initiative between Stellar’s Ivorian subsidiary, Aucrest SARL, and MetalsGrove Mining Ltd.'s subsidiary, MetalsGrove CDI Pty Ltd. This collaboration aims to advance Stellar’s 395.78 square kilometer exploration permit, Zuénoula, located in Côte d’Ivoire. MetalsGrove, as the project operator, can 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 by incurring a total of US$6,000,000.

Stellar President and CEO J. François Lalonde said the company is pleased with the continued exploration success at the Zuénoula Gold Project in Cote d’Ivoire.

Lalonde added that identifying and selecting the first priority gold exploration targets at the Fifty-Five Prospect is an important milestone for the Stellar-MetalsGrove Joint Venture and further validates the prospectivity of the Zuénoula Gold Project.

He also said the identification of two parallel +2.5km-long gold anomalous trends, peaking at 583ppb Au, together with favorable NE-oriented structures, highlights the potential scale of the system emerging from the Joint Venture’s systematic exploration approach.

Lalonde stated that exploration activities are now progressing to tighter-spaced infill sampling and auger drill planning to further refine these targets ahead of deeper drilling, while additional assay results and ongoing regional programs continue to build momentum across the project.
