CEO.CA Chairman's Briefing

Vancouver, British Columbia--(Newsfile Corp. - December 20, 2022) - Thor Explorations Ltd. (TSXV: THX) (AIM: THX) ("Thor" or the "Company") is pleased to announce drill-intersections of significant gold mineralisation from the Makosa gold deposit ("Makosa") at its Douta Gold Project, Senegal (the "Douta Project").

The Douta Gold Project encompasses the Makosa gold deposit which currently comprises an Inferred Resource of 730,000 ounces of gold, grading at 1.53 grams per ton ("g/t"), as announced in its maiden Mineral Resource Estimate ("MRE") published on 18 November 2021.

A comprehensive 26,000 metre exploration program of reverse circulation ("RC") drilling has been ongoing at Douta during 2022, and was designed to upgrade parts of the existing resource and to specifically target potentially higher-grade parts of the deposit. Further to the initial drilling results published on 16 November and 12 September 2022, the Company today publishes the results from the final 8,000 metres drilled.

Highlights include:

• Drillhole DTRC596 40m at 1.95g/t Au from 0m
• Drillhole DTRC640 26m at 4.66g/t Au from 42m including 10m at 10.29g/t Au
• Drillhole DTRC612 32m at 1.45g/t Au from 43m
• Drillhole DTRC620 9m at 11.74g/t Au from 58m
• Drillhole DTRC626 9m at 4.18g/t Au from 0m
• Drillhole DTRC624 16m at 2.20g/t Au from 85m
• Drillhole DTRC637 38m at 1.01g/t Au from 42m
• Drillhole DTRC641 31m at 1.40g/t Au from 97m
• Drillhole DTRC658 37m at 1.18g/t Au from 37m

Segun Lawson, President and CEO, stated:

"We are pleased to announce further significant and robust drilling results from the Makosa Prospect. These results are impressive and highly encouraging in the context of the Douta Project and conclude a highly successful drilling season on a celebratory note. The wide zones of near-surface oxide mineralisation combined with solid higher-grade zones at depth provide the encouragement and impetus to propel the next phase of advancing this very exciting project in the New Year. In the coming year our we plan to maintain focus both on resource growth and project development in Senegal to meet our objective of bringing the Company's second gold mine into production."

The Company has now received all outstanding drilling results from the Makosa drilling campaign and now awaits the results from the infill programs carried out at the Mansa and Maka Prospects. These results are expected in the early 2023.

Introduction
The Douta Gold Project is a gold exploration permit that covers an area of 103 square kilometres (km²) and is located within the Kéniéba inlier, eastern Senegal. The northeast trending permit (Figure 1) has an area of 103 km². Thor, through its wholly owned subsidiary African Star Resources Incorporated ("African Star"), has acquired, 70% of the licence from the permit holder International Mining Company SARL ("IMC"). IMC has a 30% free carry until the announcement by Thor of a Probable Reserve.

The Douta permit is strategically positioned 4km east of the Massawa North and Massawa Central deposits which form part of the world class Sabadola-Massawa Project that is owned Endeavour Mining (Figure 1). The northern parts permit is bounded the Makabingui group of gold deposits that belong to Bassari Resources Ltd.

Makosa

The Makosa resource is currently classified as inferred. In August 2022 Thor commenced a program of follow up RC and diamond drilling with the objective of upgrading the higher-grade portions of the resource that fall within the optimised pit shell, to indicated classification.

At Makosa, zones of gold mineralisation are developed either within a sheared gabbro intrusive or within a steep north-westerly dipping sequence of meta-sedimentary rocks that are close proximity to the gabbro. Higher grade zones or shoots are suspected to occur along east-west oriented structures that cut across the main north-east trend of the mineralisation.

The significant intersections from Makosa are listed in Tables 1 and 2 using a reporting cut-off of 25 gram-metres and 10 gram-metres respectively. The full table of results is attached in Appendix 1. Drill samples were analysed by ALS Laboratories in Mali using the AA26 fire assay method (50 gram charge).

Table 1: Makosa Significant Results (>25 gram-metres: grade X true width)
(0.5g/t Au lower cut off; maximum 2m internal dilution, minimum 2m interval with included intervals at >1g/t Au over minimum 1m)

The drill results demonstrate the continuity of gold mineralisation both along strike and down dip. From the results of the latest drilling, which include 9m at 11.74g/t Au and 10m at 10.29g/t Au, it appears that several of the anticipated high-grade zones have been intersected in the closer spaced drill pattern.

To date only the higher-grade sections of the Makosa resource have been targeted for an upgrade resource classification. Further infill drilling is warranted along the entire strike-length as better grades and continuity seem to correlate with a tighter drill spacing. Figures 3 and 4 below, demonstrate the down-dip continuity of mineralisation located in the central parts of the Makosa deposit.

• Drillhole DTRC431 6m at 4.80g/t Au from 12m
• Drillhole DTRC491 2m at 6.39g/t Au from 8m
• Drillhole DTRC493 6m at 2.58g/t Au from 57m
• Drillhole DTRC497 2m at 5.85g/t Au from 26m

Mansa Prospect²

• Drillhole DTRC363 4m at 3.11g/t Au from 55m
• Drillhole DTRC347 5m at 1.75g/t Au from 48m
