The Directors of Thor Mining PLC (“Thor” or the “Company”) (AIM, ASX: THR), are pleased to advise that bedrock geochemistry drilling has commenced at the Dundas Project in southern Western Australia.
Mr Mick Billing, Executive Chairman of Thor:
“The Albany-Fraser belt in Western Australia hosts a number of gold deposits, including the >8million ounce Tropicana deposit north of Dundas, which was discovered after drilling weakly elevated gold anomalism. The alluvial cover at Dundas can be 30 metres thick, thereby masking or diluting any potential surface anomalism. By drilling into the top of bedrock, we hope to intersect stronger values of gold and other indicator minerals which would significantly elevate this project.”

The program is designed to test two northwest – southeast trending zones of elevated gold in calcrete identified from a BHP geochemistry survey conducted in the 1990’s. The two zones, named Algron and Bifrost (Figure 2), extend over five kilometres trend parallel to the regional aeromagnetic response.
Figure 2: Calcrete Geochemistry Results
The drill program will comprise 50 air-core holes to test the bedrock geochemistry beneath the six best surface calcrete geochemistry results to determine if the elevated gold values at the ground surface represent mineralisation in the underlying bedrock.
The program is a second exploratory phase where a successful outcome would be the intersection of elevated indicator elements such as arsenic, copper or possibly gold measured in parts per billion. A direct hit on potentially economic grades of mineralisation is possible but not expected for a successful program outcome. If successful, follow up deeper reverse circulation drilling will be scheduled to test for potentially economic grades.
The program should take approximately 10 days with assays results within four weeks.
About the Dundas Project
The Thor Dundas Project is situated in Western Australia within the Albany-Fraser Province. The project tenement is situated in the prospective Albany-Fraser belt (Figure. 3) where the trend of the belt is displaced south-eastwards by about 50km co-incident with the general strike-extension of the most prolific gold-bearing belt of the Yilgarn Province – the Wiluna-Kalgoorlie-Norseman greenstone belt. The Albany-Fraser belt hosts a number of gold discoveries including the +8 million ounce Tropicana gold deposit, and other closer discoveries.
Thor Mining holds 60% equity in the Dundas project along with rights to increase that equity to 100%.
