Thor Announces High Grade Results From Makosa Tail Prospect, Senegal






Thor Explorations Ltd. (TSX-V: THX) is pleased to announce an encouraging set of drill results from the southern Makosa Tail Prospect at its Douta Project, Senegal. The exploratory drilling program was designed to test the mineralisation along strike and down dip from the mineralisation delineated from previous drill programs on Makosa. The results received to date confirm the continuation of the Makosa mineralised system along strike to the south.


Highlights include:


  • Makosa Tail Prospect mineralisation confirmed over 1,000m of strike length in a number of parallel lodes including a 300m high grade zone in a previously untested area.
  • Drillhole DTRC149

    °  5m at 14.38g/tAu from 36m including 1m @ 57.90g/tAu

  • Drillhole DTRC145

    °  5m at 6.90g/tAu from 15m including 2m @ 12.94g/tAu

  • Drillhole DTRC150

    °  10m at 2.18g/t from 24m including 2m @4.80g/tAu

  • Mineralisation remains open ended to the north, south and at depth




The Douta Gold Project is a gold exploration permit that covers an area of 103 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 licence is strategically positioned 4km east of the deposits Massawa North and Massawa Central deposits which form part of the world class Sabadola-Massawa Project that is owned by Teranga Gold Corporation (Figure 1).


In late 2020 a total of 1,567m of drilling was completed in 21 RC drillholes over the Makosa Tail prospect in order to test for possible southern extensions of the Makosa mineralised system (Figure 2).


Drilling Results


The results are from the exploratory RC drilling program at Makosa Tail are shown in Table 1 and Figure 2. The full table of results is attached in Appendix 1.

Table 1: Makosa Tail Significant results
(0.5g/tAu lower cut off; maximum 2m internal dilution)


The RC program was completed using a line spacing of 100m over the northern parts of Makosa Tail and 200m-spaced reconnaissance sections towards the south. The holes averaged 74m in length with the deepest hole completed to 100m.


Drill samples were analysed by ALS laboratories in Mali using the AA26 fire assay method (50g charge).


The results indicate up to four parallel, steep north-westerly dipping, mineralised horizons that are developed within a shale/greywacke sequence. Most significant, is the discovery of several higher grade zones towards the southern end of the drilled area where the drill coverage is wide-spaced.


Drillhole DTRC145 returned 5m at 6.90g/tAu from 15m (Figure 2). The same mineralised horizon was intersected 200m to the south by hole DTRC149 which returned 5m at 14.38g/tAu from 36m.


On the northern-most section hole DTRC138 returned patchy low-grade mineralisation from 18 to 79m down hole (Appendix 1) and the nearby hole DTRC139 returned 5m grading 1.88g/tAu from 31m downhole. Together, the results from these two holes indicate continuation of mineralisation to the north towards Makosa Prospect. There is approximately 1,600m of untested strike length between Makosa Tail and Makosa.


Two holes DTRC152 and DTRC153 on the southern-most section returned no significant result (NSR). Further drilling in this area is required to achieve full drill-coverage to confirm whether not the mineralised system is closed off or whether the mineralised zone has been displaced by late-stage faulting.




The Makosa Tail drilling has intersected multiple parallel lodes over a strike length of 1,000m with a higher grade zone potentially extending for 300m.


Significantly, there is a 1,600m strike length between Makosa Tail and Makosa that is yet to be drill-tested.


Systematic infill and step-out drilling is planned to fully assess the ever-increasing scale of the project.


Segun Lawson, President & CEO, stated:


“We are thrilled with these drill results. We are particularly pleased with the uplift in grade of the intersections which are all in a previously untested area. The Makosa Tail Prospect is open to the north and possibly to the south and we look forward to investigating if the mineralisation extends to the Makosa mineralised system. Makosa as a whole continues to grow with our drilling and understanding of the geology and we are excited about the next phase of drilling scheduled to start this month.”
