Thor Explorations Increases Stake to 100%

Interest in the Douta Project and Completes

the Acquisition of Bousankhoba Permit in

Southeast Senegal

Vancouver, British Columbia--(Newsfile Corp. - September 8, 2025) - Thor Explorations Ltd (TSXV:

THX) (AIM: THX) ("

Thor

" or the "

Company

") is pleased to announce that it has signed a binding sale

and purchase agreement ("

SPA

") with its Douta Project joint venture ("

JV

") partner, International Mining

Company SARL ("

IMC

"), to acquire IMC's entire outstanding 30% economic interest (the "

Acquisition

")

in the Douta Gold Project in Senegal ("

Douta"

)

.

The completion of the acquisition moves Thor's interest

in Douta from 70% to 100%.

The Acquisition will be subject to the completion of certain conditions precedent including final approval

from the Minister of Mines. The total consideration for the Acquisition is a cash payment of

US$3,000,000 and a 1.5% Net Smelter Royalty ("

NSR

"). 50% of the cash payment is payable on

signing and 50% is payable at completion. The NSR is capped up to a maximum of US$60 million.

In addition to the Acquisition, the Company has also acquired an initial 65% interest in the Bousankhoba

Exploration Permit EL02254 ("

Bousankhoba

"). Bousankhoba is an early-stage gold exploration permit

located contiguous to the east of the Company's Douta West permit (Figure 1). Extensive first stage

exploration completed over Bousankhoba has identified numerous geochemical targets associated with

a major shear zone over an 18 kilometre ("

km

") strike length. Two prospects, Massa Massa and

Sekhoto, are located along this zone. An additional prospect known as the Sakhofara is located 7km

east of Massa Massa in the northern part of the permit and is defined by a 3.5km north-east trending

geochemical anomaly. Historical early-stage drilling carried out by the prior owners of the licence has

only tested the Sekhoto prospect, producing encouraging results including 10 metres ("

m

") at 3.6

grammes per tonne ("

g/t

") of gold ("

Au

") and 2m at 52g/t Au.

The terms of the Bousankhoba earn-in include a minimum exploration program over 24 months and an

earn-in payment of US$160,000 payable within the first six months of signing.

Segun Lawson, President & CEO, stated

:

"We are delighted to have agreed terms and signed binding agreements with IMC, our Douta Project

joint venture partner, to complete this important and strategic acquisition. This is an acquisition of the

remaining 30% economic interest in the Douta Project that we did not previously own. We appreciate

the significant role of IMC in assisting our journey in Senegal since the acquisition of our initial

interest in Douta as a grass roots exploration project. We are also thankful for IMC's dedication to

making this transaction efficient and look forward to continuing our productive relationship with IMC

who continue to provide invaluable in-country assistance and guidance.

"With the Douta Project Preliminary Feasibility Study at an advanced stage, there is compelling

strategic rationale for the Acquisition. This is a project we are very much looking forward to building.

Owning it on a 100% basis allows for an efficient development process and full exposure to the project

economics prior to the Government's 10% free carried interest.

"We are also delighted to have completed the acquisition of a 65% joint venture initial interest in the

Bousankhoba Permit. This permit increases the footprint of the Douta Project for regional exploration.

Historical drilling at Bousankhoba shows encouraging mineralisation that potentially could be

extensions to mineralisation being presently tested at Baraka 3.

"We are positioned to deliver the Douta Preliminary Feasibility Study in Q4 2025 on a 100%

ownership basis, with significant exploration upside potential and providing us with an expanded

project and exploration footprint in Senegal."

Bousankhoba Overview

Geology

The Douta Gold Project, including the Bousankhoba permit, is located within the Birimian Kéniéba inlier

of eastern Senegal. The Bousankhoba permit is underlain by rocks belonging to the Dialé-Daléma

Supergroup that comprise sedimentary and volcano-sedimentary units which have undergone

greenschist facies metamorphosed. Localised occurrences of amphibolite facies occur in the vicinity of

later-stage intrusive bodies. The rocks within the Bousankoba permit comprise alternating detrital facies,

including sometimes schistose clays, greywackes, and graphitic schists. In addition, there are volcano-

sedimentary elements represented by coarse to fine lapilli tuffs.

The Major Transcurrent Zone ("

MTZ

") is the main structural feature of the area and is located to the west

of the permit. The MTZ coincides with the contact between the Mako Supergroup and the Dialé-Daléma

Supergroup.

Exploration

In the years 1998-2000, the German company Hansa Geomin undertook gold exploration work, primarily

soil geochemistry using an average grid of 200m x 100m. A total of 20,243 samples were collected and

assayed for gold. The results of this program revealed significant north-east trending geochemical

anomalism over an 18km strike length in the western portion of the permit (Figure 2).

In 2007, the permit was granted to Libah Investment, which, in a JV with the Australian company Bassari

Resources, also undertook additional exploration work between 2009 and 2016, including termite

mound and rock geochemistry (541 samples), regolith mapping, trenching, and Rotary Air Blast ("

RAB

")

drilling at the Sekhoto prospect. A total of 241 angled RAB holes were drilled for 10,959m at an average

depth of 45m. Significant results from the trenching and drilling are shown in Tables 1 and 2 respectively.

Table 2: Significant RAB Drilling Results

At the Sekhoto Prospect, mineralisation has been identified over a strike length of approximately 1.5km

and coincides with a prominent north-easterly trending shear zone (Figure 4). Several partially tested

parallel structures are developed to the west and east of this main shear zone.

Exploration Opportunities

Extensive first stage exploration, completed over the Bousankhoba permit, has identified numerous

geochemical targets associated with a major shear zone over an 18km strike length. Two prospects,

Massa Massa and Sekhoto, are located along this zone. An additional prospect known as the Sakhofara

is located 7km east of Massa Massa in the northern part of the permit and is defined by a 3.5km north-

east trending geochemical anomaly.

To date, follow-up RAB drilling has only been confined to the Sekhoto Prospect has been drilled. The

significant intersections obtained in the RAB drilling are yet to be followed with systematic reverse

circulation ("RC").

The prospectivity of the permit is further enhanced by its location between Baraka 3 to the south and

Basari Resource's 1 million ounce Makabingui deposit to the north. It is possible that the mineralised

shear zone extends through all three gold occurrences.

Thor considers the Bousankhoba permit to be highly prospective with the potential to provide satellite

resources that will complement the Douta Gold Project.

Douta Project Overview

The Douta Gold Project comprises three exploration permits located within the Kéniéba inlier, eastern

Senegal. The Douta mining lease application (Demande) No.11618 (formerly EL02038) is held by Thor,

through its wholly owned subsidiary African Star Resources Incorporated (

"African Star"

) and now

owns a 100% economic interest in the licence.

The Douta-West exploration licence is also held by Thor through African Star, which acquired a 70%

economic interest in the licence through a joint venture agreement with the permit holder Birima Gold

Resources Consulting ("

Birima Gold

"). Birima Gold has a 30% free carry until the completion of a

Preliminary Feasibility Study, at which point Birima must contribute to exploration and development

funding of the licence or have their economic interest diluted to a minimum 5% free carry.

The Douta-West Project, comprising exploration permit E03709, is contiguous with Thor's Demande

No.11618 (Figure 1). Douta-West is operated by Thor under an agreement with Birima Gold Resources

Consulting and encompasses several historic gold-in-soil geochemical anomalies that extend south from

the southern end of the Makosa Tail prospect and that also run parallel and to the north of the known

Makosa trend in a corridor that occupies the ground between Makosa and Endeavour Mining's Masawa

gold mine.
