Segun Lawson, President & CEO, stated:

"I am pleased to report continued strong operational performance for the third quarter of the year, meaning we are on track to meet our production and cost guidance for 2025. By choosing to remain unhedged, we have been able to take full advantage of the high prevailing gold prices, resulting in an average realised price of US$3,535 per ounce, maximising the benefit for our shareholders. At the end of the Quarter, our inventory contained just under 6,000 ounces of gold in bullion and doré that remained unsold and was exposed to higher prevailing gold prices.

"During the Quarter, we also completed the major strategic milestone of consolidating our ownership position in the Douta Project, reinforcing our commitment to its long-term development and simplifying the pathway for project execution. In line with this strategic focus in Senegal, we have further strengthened the growth potential of Douta by advancing exploration activities at Baraka 3 and securing the Bousankhoba licence, which lies contiguous to the existing Douta project permits. These initiatives are targeted to significantly expand our long-term resource inventory and further support our ambitious growth strategy.

"Drilling at Segilola has continued, providing further support to our geological model. We successfully drilled several high grade, mineable intersections beneath the current open pit design. The drilling will continue through the year and is planned to target the potential extension of mineralisation, both in the north and the south, at greater depth where mineralised shoots continue to be defined and remain open at depth.

"Exploration campaigns across the Company's portfolio slowed during the wet season, and I am eagerly awaiting the planned re-start of programs at Baraka 3 in Senegal, Guitry in Cote d'Ivoire, and commencement of our maiden program at Marahui in Côte d'Ivoire."

Exploration Q3 2025 Highlights

Nigeria (Segilola)

• A diamond drilling program that commenced in 2024 continues to test the continuity of mineralisation following the down-plunge trend to the south. To date, a total of 74 holes have been completed for 20,496 metres ("m"). Drilling has focused on two main areas:

  • Northern Zone: Targeted mineralisation is confined to a discrete, west-dipping, 100m long shoot with an apparent pronounced steep southerly plunge.

  • Southern Zone: Mineralisation appears to have a shallow-plunging flat geometry.

• The Company is pleased to announce continued further positive drilling results from this ongoing diamond drilling program. Significant drill results in the Quarter include:

(>3gram-metres, 0.5g/tAu cut off, Min. length 0.5m, Max. internal dilution 1m)

• Significant drill results exceeding 3 gram-metres (calculated as average grade multiplied by true width) are highlighted in the Longitudinal section (Figure 1) and detailed in Table 3, underscoring the strong mineralisation identified during this campaign. A comprehensive list of all recent results can be found in Table 4.

Senegal (Douta)

• During the Quarter, the Company secured full ownership of the Douta Project by entering into a binding sale and purchase agreement with International Mining Company SARL ("IMC") to acquire the remaining 30% minority equity interest. With this acquisition, subject to standard conditions precedent, the Company will hold 100% of the permit.

• In accordance with the Senegal Mining Code, upon issuance of the Douta Mining Concession (Concession Minière), the State of Senegal will be granted a 10% free carried interest in the operating company.

• The extended drilling program at Baraka 3 was completed during the Quarter, and metallurgical testwork is nearing completion. It is anticipated that a Baraka 3 resource will be included in an updated Douta Resource and Douta PFS.

• Additional exploration drilling programs at Baraka 3 are scheduled to resume in October, aligning with the beginning of the dry season. To accelerate the evaluation of the numerous identified geochemical targets, our contractor has imported an additional RAB rig. This additional rig will supplement the current fleet which includes two RC rigs and one multi-purpose diamond / RC rig already on site.

• In addition to the IMC acquisition, the Company has also acquired an initial 65% interest in the Bousankhoba Exploration Permit EL02254, an early-stage gold exploration permit contiguous to the east of the Company's Douta West permit (see Figure 2). Bousankhoba contains several continuous soil geochemical anomalies, with some areas having undergone historical early-stage drilling yielding encouraging results.

• Management considers Bousankhoba to be highly prospective and has the potential to deliver satellite resources that will enhance the Douta Gold Project, representing another promising opportunity as has been identified at Baraka 3.

• A large-scale RAB drilling campaign is being planned for Bousankhoba and is scheduled to commence early next year, following the completion of a similar program at Baraka 3.

• Douta PFS work streams are continuing, with the aim of completing the PFS in Q4 2025.

Côte d'Ivoire

Guitry Project

• During the Quarter, the Company completed a successful maiden drilling program comprising 4,604 m in 41 holes. This drilling campaign has intersected and confirmed previously untested deeper bedrock mineralisation, which remains open.

• In the final quarter of the year following conclusion of the rainy season, the Company intends to implement the following plan.

  • Additional step-out drilling programs.

  • Orientated core diamond drilling to confirm and further understand the structural geology of the underlying formations.

  • A comprehensive permit-wide auger drilling campaign to investigate the previously identified soil anomalies, thereby enhancing our understanding of the project's broader mineral potential.

Marahui Project

• Exploration activities progressed, featuring extensive geological mapping and consistently encouraging results from both rock chip and soil geochemical sampling.

• A preliminary drilling program totalling 9,000 m has been planned. The initial drill pads are already prepared, and drilling operations are set to commence following conclusion of the national elections.
