The directors of Thor Mining Plc ("Thor") (AIM, ASX: THR) are pleased to provide an update on the Kapunda ISR (Insitu Recovery) project being progressed by EnviroCopper Limited.

EnviroCopper Limited, via subsidiary Environmental Copper Recovery Pty Ltd, 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").  Thor hold a 25% interest in EnviroCopper Limited with rights to increase that interest to 30%.

Earlier in the year, on 2 April 2019, Thor advised proof of concept for gold recovery at Kapunda, along with reference to reported gold assays from historical information held in a South Australian Government open file report.  That announcement may be accessed on the Thor website via: 


The open file report¹ referred to in that announcement was The South Australian Government open file report (Open File Envelope No. 1651) "Kapunda Mine: Technical and Progress Reports for Period 1970-1971" submitted in 1971, which can be accessed via 

¹The Exploration Information, including assay results, contained in the "Kapunda Mine Report (1971)" are historical in nature and have not been verified by a Competent Person, and were not prepared in accordance with the requirements of the current JORC Code.

Subsequently the Company has become aware of a further public document which reports on findings of IP (Induced Polarisation) surveys, suggesting that targets for Kapunda style mineralisation extend up to 4.5 kilometres south of the known Kapunda resource.  This report may be accessed via:


Mr Mick Billing, Executive Chairman, commented: 

"The momentum behind the Kapunda project continues to develop, particularly as its emerging gold potential is recognised."

"We look forward to assays from the recent program of drilling and pump testing at Kapunda to add further weight to the story"

"In addition to the existing schedule of developing the feasibility of ISR production at Kapunda from the existing published resource estimate, substantial potential is emerging to extend and add to this, as well as potentially quantifying the gold mineralisation and we look forward updating investors on the strategy for this in the near term."
