Vancouver, British Columbia--(Newsfile Corp. - September 15, 2026) - Thor Explorations Ltd. (TSXV: THX) (AIM: THX) ("Thor" or the "Company") is pleased to announce encouraging maiden exploration drilling results from its Marahui Gold Project ("Marahui" or the "Licence") in northeastern Côte d'Ivoire. The project forms part of a portfolio of early-stage exploration licences in Côte d'Ivoire which also includes the 100% owned Guitry Gold Exploration Project, and an option to earn up to an 80% interest in the Boundiali Exploration Permit, located in north-west Côte d'Ivoire.

Highlights

The assay results include:

• Drillhole MRRC26-008 - 6 metres ("m") at 5.60 grams per tonne ("g/t") Au from 129m
• Drillhole MRRC26-012 - 9m at 5.40 g/t Au from 40m
• Drillhole MRRC26-115 - 6m at 6.20 g/t Au from 74m
• Drillhole MRRC26-053 - 8m at 3.60 g/t Au from 35m
• Drillhole MRRC26-143 - 8m at 3.40 g/t Au from 50m
• Drillhole MRRC26-052 - 5m at 3.60 g/t Au from 75m

Segun Lawson, President & CEO, stated:

"We are extremely encouraged by this maiden set of drilling results which have followed the initial early exploration success at this Licence.

"These encouraging results show high-grade mineralisation at a significant strike length demonstrating the potential scale of Marahui and are an important step forward for Thor's exploration portfolio in Côte d'Ivoire. Wide, high-grade intersections which are characterised over a 4km strike length, including 6m at 6.20g/t Au, 9m at 5.40g.t Au and 6m at 5.60g/t Au reinforce our already high confidence in the Licence.

"The scale of the opportunity is particularly encouraging. The drilling to date has identified multiple parallel gold-bearing veins within a shear corridor extending over more than 4 km, yet drilling has tested only approximately 30% of the overall geological trend. With further additional geochemical anomalies already defined within the Licence, we have a clear pipeline of targets to test with our ongoing drilling program.

"Marahui remains at an early stage, and we are delighted to start with these encouraging results which open up a material and exciting new exploration opportunity for Thor. We look forward to testing the additional targets over the coming months and reporting the remaining pending results as we build a clear understanding of the project's scale and potential."

Introduction

The Marahui Project comprises exploration permit PR902, covers 250 square kilometres (km²) and is located in the Bondoukou Region of northeastern Côte d'Ivoire (Figure 1).

The Marahui permit is underlain by an arcuate, north-westerly trending sequence, Birimian schistose volcano sedimentary rocks, which are surrounded by intrusive granites. In the contact zone, volcano-sediments show strong foliation and silicification. Observed gold mineralisation is controlled by a NW-SE shear zone in volcano-sediment schists and by extensional WNW-ESE quartz veins in granite.

Previous soil geochemical sampling and geological mapping around artisanal workings identified two parallel anomalous structures. The larger anomaly extends for approximately 4 kilometres ("km") and is approximately 200m wide. Follow-up rock-chip sampling of material from artisanal workings along this structure confirmed bedrock gold mineralisation, returning values of up to 23.1g/t Au (Figure 2).

Marahui Exploration Drilling Results
Thor has carried out 18,439m of its budgeted 25,000m reverse circulation ("RC") drilling program as part of its ongoing exploration programme, which is focused on a north-westerly-trending line of shallow artisanal workings.

Drill samples are analysed by SGS Laboratories in Yamoussoukro using the FAA505 fire assay method with a 50g charge. Significant intersections are presented in Table 1, and the complete drillhole summary is provided in Appendix 1.

Gold mineralisation occurs in a subvertical, en-echelon vein array within a north-westerly-trending shear zone approximately 200m wide and extending for more than 4km along strike (Figure 2). Drill-line spacing ranges from 100m to 400m. Results to date suggest that individual veins have apparent strike continuity of up to 700m and estimated true widths of up to approximately 7m.

Drilling to date has tested approximately 30% of the overall geological trend. Additional discrete geochemical anomalies have been identified along the trend and are scheduled for drill testing in the coming months. The Company considers the initial results highly encouraging, highlighting a new exploration opportunity with the potential to support a future standalone operation, subject to further exploration and technical and economic evaluation.

Conclusions
Initial RC drilling at Marahui has confirmed gold-bearing vein mineralisation within a northwesterly-trending shear corridor approximately 200 m wide and extending for more than 4km. Mineralisation occurs in a subvertical, en-echelon vein array, with results to date suggesting apparent strike continuity of up to 700 m for individual veins and estimated true widths of up to approximately 7m.

Thor has completed 171 RC drillholes testing the interpreted shear zone. The program is ongoing and assays remain pending, to be released as received. Significant intersections include 6m at 6.20g/tAu from 74m in MRRC26-115, 6m at 5.60g/tAu from 129 m in MRRC26-008 and 8m at 3.40g/t Au from 50m in MRRC26-143. These intervals are downhole lengths.

With approximately 30% of the overall geological trend tested by drilling, considerable scope remains for further exploration. Additional discrete geochemical anomalies have already been identified and are scheduled for drill testing in the coming months, providing a clear pipeline of follow-up targets. These encouraging results reinforce Marahui's potential within Thor's exploration portfolio in Côte d'Ivoire and provide a strong foundation for the next phase of work. The potential for a future standalone operation remains subject to further exploration and technical and economic evaluation.
