Thor Mining (THR) has encountered positive results from an initial hydrogeological drill program at the Kapunda Copper ISR Project in South Australia.
The drilling program was carried out by EnviroCopper with aims to determine the fracture connectivity between wells as well as the aquifer properties.
One pilot hole was drilled to determine the geology, ore distribution, and water yielding zones. This was followed by two additional bore holes which were drilled and cased as test production bores.
Samples from these holes were analysed via portable X-ray fluorescence analysis and then sent to laboratories for chemical analysis to confirm copper concentration.
Results peaked at 0.72 per cent copper, returning values that were higher than expected.
Gold was identified with grades peaking at 0.03 parts per million, confirming the presence of the mineral in the system.
“Very solid progress is being made by EnviroCopper at the Kapunda copper ISR (in-situ recovery) project, continuing to confirm the potential for production of copper using ISR, against a background of rising copper prices,” Executive Chairman Mick Billing said.
“There is a very busy schedule of activities during the second half of calendar 2020 with potential to add significant investor value via gold focused drilling, and more field test activities to further demonstrate the potential for economic ISR production at Kapunda,” Mick said.
Initial scoping studies were then undertaken to determine if any significant chemical or physical issues may exclude a particular method of copper production.
Each of the studies – ion exchange, cementation, and electrowinning – demonstrated a successful copper recovery.
Over the next six months, Thor will undertake preparations for a Site Environmental Lixiviant Test (SELT), and gold and geotechnical drilling programs.
Both of these programs are planned to begin in October, however, this is dependent on receiving approval from various government and local government agencies.
Thor has ended the day with no change and shares have been trading for 0.7 cents each since July 23.
