ISR Explanatory Video

The directors of Thor Mining Plc ("Thor" or the "Company") (AIM, ASX: THR, OTCQB: THORF) are pleased to announce that the Company has published an educational, explanatory video on In Situ Recovery ("ISR') and how it will be utilised at the Company's Alford East Copper Project in South Australia.

ISR is an innovative mining technique that has a minimal impact on the surrounding environment in contrast to conventional open cut mining, and can take place simultaneously alongside other landuses, such as farming. ISR is not new and has been used for decades successfulfully to extract uranium and potash. Over the past three years, EnviroCopper Ltd ("ECL"), along with researchers from the Commonwealth Scientific and Industrial Research Organisation ("CSIRO") and The University of Adelaide, have shown proof of concept that ISR can be adapted for use at copper and gold projects in Australia, in addition there are now several ISR copper operations in the Arizona, USA including Gunnison Project, Excelsior Mining Corp.

The video can be found on the Thor website and Thor YouTube channel via this link: https://www.youtube.com/watch?v=eG_1ZGD0WIw

Thor is earning an 80% interest in copper deposits amenable to ISR production at Alford East, as well as holding a 30% interest in ECL, the holder and operator of the Kapunda and Alford West copper projects, also located in South Australia and considered amenable to ISR.

Nicole Galloway Warland, Managing Director of Thor Mining, commented:

"We are pleased to publish this video explaining how in-situ recovery will be used at the Company's Alford East Copper Project in South Australia. ISR is an environmentally sustainable technique which reduces the impact of mining activities on the land, as well as mining costs associated with the extraction of ore. Thor is delighted to be at the forefront of the industry with regards to the implementation of this technology and we look forward to seeing this technique utilised across the projects within our portfolio."
