PROOF OF CONCEPT ESTABLISHED - KAPUNDA COPPER PROJECT
The Board of Thor Mining Plc ("Thor" or the "Company") (AIM, ASX: THR), is pleased to advise that proof of concept has been established for Insitu-Recovery of copper at the Kapunda Copper Project, in partnership with Environmental Copper Recovery SA Pty Ltd ("ECR").
The Kapunda Copper project, in which the Company has a right to earn into a 45% effective interest, holds an inferred JORC compliant resource of 119,000 tonnes of copper, as per the maiden resource estimate announced in February 2018 by Thor Mining (in partnership with Environmental Copper Recovery SA Pty Ltd ("ECR")) and Terramin Pty Ltd (ASX: TZN).
The Kapunda project follows a typical series of well-defined project development steps with each step being a "go, no-go" decision point. The Proof of Concept of Insitu-Recovery (ISR) for the project is a significant step forward in the project development process.
· Positive Initial hydrogeological assessment and water sampling completed;
· Construction of the necessary technical models of geology, ore grade, copper species distribution, and fracture density;
· Initial hydrogeological computer modelling which suggests that flow through the ore body is possible and the geology is amenable for ISR;
· Successful completion of preliminary laboratory work, and determined the copper species present are recoverable;
· Initial implementation of a community education program for community on benefits of ISR;
· Stage 2 work commenced.
Mr Mick Billing, Executive Chairman, commented:
"The proof of concept stage has been successful in demonstrating that, from both a technical and social viewpoint, we should proceed to the next stage of work. This next stage (stage 2) will include: relevant approval processes, pump and environmental testing, and will incorporate a field recovery trial to generate solution and test a variety of metal recovery options."
"The successful completion of these stages was complemented by the receipt of a (CRC-P) Commonwealth Research Program Grant for A$2.85 million for the Kapunda Copper ISR project, further supporting this exciting initiative of an economically and environmentally sustainable mining future technique."
"We look forward to providing further information on this exciting project, and each of our other projects at Molyhil (including Bonya), and Pilot Mountain in the coming weeks."

Mr Faulkner is an employee of Environmental Copper Recovery Pty Ltd. He has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves'. Leon Faulkner consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
The Kapunda copper project is located approximately 90 kilometres north of Adelaide in South Australia.
On 1 August 2017, Thor announced an agreement to earn up to 60% of a newly incorporated private Australian company, Environmental Copper Recovery SA Pty Ltd, initially via convertible loan notes of up to A$1.8 million, which will be used to fund field test work and feasibility activities at Kapunda over the next 3 years.
In turn ECR has entered into an agreement to earn, in two stages, up to 75% of the rights over metals which may be recovered via in-situ recovery ("ISR") contained in the Kapunda deposit from Australian listed company, Terramin Australia Limited ("Terramin" ASX: "TZN").
For detail of the In-situ Recovery process, investors are invited to view the ECR website; https://www.envirocopper.com.au/ .
In February 2018 Thor announced an Inferred JORC Resource Estimate for the Kapunda project, of 47.4 million tonnes (MT) grading 0.25% Cu, containing 119,000 tonnes of contained copper considered amenable to In-situ Recovery techniques.
For detail of the Resource Estimate Announcement, investors are invited to view the Thor website;
Subsequently, on 30 July 2018, the Company announced details of a CRC-P (Cooperative Research Centre) grant to the value of A$2.85 million from the Australian Commonwealth Government for the Kapunda In-Situ Copper and Gold Recovery Trial.
