THOR MINING PLC
COPPER RESOURCE - KAPUNDA PROJECT, SOUTH AUSTRALIA
HIGHER GRADE CORE INFORMATION
The Board of Thor Mining Plc ("Thor" or the "Company") (AIM, ASX: THR), is pleased to announce further information on the Kapunda Resource estimate containing 119,000 tonnes of copper, considered amenable to In Situ Recovery techniques ("In Situ Recovery" or "ISR"), announced 12 February 2018, and subsequently clarified on 22 February 2018.
Thor has the right to earn up to an effective interest of 45% in that part of the Kapunda project that is considered amenable to ISR.
The Company is pleased to advise of a Central high grade core, or zone, of mineralisation, contained within the previously announced Resource boundaries, of 29.0 million tonnes, @ 0.32% copper containing 91,200 tonnes of copper.
Grade tonnage curves (Figure 1) indicate the quantity of estimated contained metal at various cut-off grades for both this high grade portion, and the broader resource announced on 12 February 2018.

Mick Billing, Executive Chairman, commented:
"The results of this analysis reinforce the very strong potential of the Kapunda deposit. This higher grade core at Kapunda is very robust, while still hosting approximately 75% of the total 119,000 tonnes of copper in the estimated Resource.
"We recognise that In Situ Recovery as a process is not necessarily a familiar area for many investors and the grades published may appear low when compared to traditionally mined copper deposits."
"However, from the standpoint of extractive metallurgy, the grades identified are ideal for In Situ leaching and the significant size of deposit outlined to date means this project has considerable potential and needs moving forward through the next stages of the development pathway."
"We are therefore extremely pleased with the results announced today and we look forward to reporting further progress through market announcements which chart the next steps in respect of project development."

Participants in the project, Environmental Copper Recovery SA Pty Ltd and Terramin Australia Limited, suggest that sections of this high grade portion (Figure 2) are likely to be the initial focus of field pump trials expected to contribute towards demonstration of both technical and commercial feasibility of the ISR process at Kapunda.
