Stellar AfricaGold - Structural Mapping Report Supports Expansion

Potential at Tichka Est; Drill Campaign Progress Report

Vancouver, British Columbia – September 11, 2025 – Stellar AfricaGold Inc. (TSX-V: SPX) ("Stellar"

or the "Company") is pleased to announce that the final report by Dr. David Selley on the structural

geology of Tichka Est confirms the exploration potential of Structure B and its possible extensions at

the Company’s Tichka Est Gold Project in Morocco.

The Selley Report

The Company received the final detailed report on the ‘Structural Analysis of the Tichka Est Prospect,

High Atlas, Morocco’ from Dr. David Selley of Base Instinct. This compilation and analysis of structural

mapping, alteration studies, and minerali zation provides the most comprehensive understanding to

date of the gold potential of Structure B, outlines the regional potential of the Tichka Est Gold Project,

and provides a window to the opportunity for value creation through additional gold discovery at Tichka

Est.

CEO Commentary

“Dr. Selley’s in-depth structural mapping report supports expansion of Stellar’s planned drill program

and gives us tremendous confidence in the immediate upside potential for additional near-term gold

discoveries at Tichka Est ,” said François Lalonde, CEO of Stellar AfricaGold. “ The combination of

Structure B’s scale, the structural junctions with Structures A and C, and the intensity of alteration

confirm we are in a fertile gold system. With current drill targets clearly defined, we are excited to

maintain the pace of exploration activities and move quickly into the next phase of drilling.”

Key Findings from the Structural Report

The Structural Report confirms that:

• Structure B hosts a strong gold-bearing system located at the intersection of the NE-striking

Tizgui Fault Zone and the ENE -striking Arg-Erdouz Fault Zone (Figure 1). This favourable structural

setting has created a transpressive domain that focuses gold mineralisation within brittle deformed

carbonate strata intruded by diorite sills (Figure 2).

• Gold Mineralisation is closely associated with quartz -ankerite-arsenopyrite-bearing veins,

marked by distinctive deep red limonitic alteration, hosted preferentially along sill margins and in zones

of structural decoupling.

• Alteration signatures (notably deep red limonitic halos) are intense and dominated by Fe -

carbonate halos, overprinting regional chloritic facies (Figure 3). These alteration zones, combined

with the abundance of high-density vein arrays, reflect a strong hydrothermal system.

• In addition to the current confirmatory drilling program, three high -priority targets have been

identified for the next phase of drilling (Figure 1):

1. The junction of Structures B and C , where structural corridors converge, creating a

potential trap for high-grade mineralisation.

2. The northern continuation of Structure B, marked by alteration zones suggesting

system extension.

3. The junction between Structures A and B , where limonitic dykes point to a possible

feeder system.

Unlocking Value at Tichka Est

The findings within Dr’ Selley’s report open the door to further value creation at Tichka Est:

• Confirm the potential to further expand Structure B along strike and at depth (400–600 meters drill

targets).

• Prioritize the structural junctions of the A and B structures and the B and C structures as new high-

value drill targets.

• Provide an expanding geological model that reinforces Tichka Est’s potential as a multi-structure

gold system.

Drill Campaign Progress Report

The diamond drilling campaign continues to advance with the third drillhole reaching a depth of 124

metres as of Thursday, September 4. Operations are scheduled to resume this week following a brief

holiday break and road maintenance required following recent flooding in the area of the project.

Regarding assays, Stellar’s geologist supervised the core cutting and sample preparation for the first

drillhole. The samples have now been delivered to the lab for analysis, with results expected in the

normal course.

About the Tichka Est Gold Project

The Tichka Est Gold Project is comprised of seven permits covering an area of 82km 2 located in the

High Altas region of Morocco approximately 90km south of Marrakech. Under an earn -in agreement

with Morocco’s National Office for Hydrocarbons and Mining (ONYHM) Stellar can earn an 85% interest

after incurring exploration expenditures totaling US$2.39M (C$3.5M) over three years.

To date early-stage exploration (mapping, sampling, trenching and a small first pass RC drill program)

has identified three gold -bearing zones: Zone A extending over 450 meters along strike, Zone B:

extending over two kilometers along strike and Zone C extending over two kilometers along strike.

Additionally, regional stream sediment sampling over a 12km2 area surrounding the three known gold

zones identified numerous other anomalous metal zones that warrant further mapping and sampling .

These new zones of mineralization include: 6 zones anomalous for gold, 5 zones anomalous for silver,

2 zones anomalous for copper and 3 zones anomalous for lead and zinc. Most of the overall property

areas are unexplored or only superficially explored.
