Thor Mining (THR) has commenced copper recovery trials at its Kapunda Copper ISR Project in South Australia.
The site is based roughly 90 kilometres north-north-east of Adelaide.
The company advised the market that pump testing and a tracer test, to be followed by an in-situ lixiviant trial, have commenced at the Kapunda project.
These tests need to be carried out by EnviroCopper (ECL), in which Thor holds a 30-per-cent equity interest, before ECL can take on Site Environmental Lixiviant Trails at the project.
According to the company, the lixiviant test helps assess the solubility of copper mineralisation, and therefore the recovery of copper, using a purpose-made solution called a lixiviant under in-situ conditions.
Thor has advised the testing processes would take between three and four weeks.
The company flagged its plans for lixiviant testing in a July 23 announcement highlighting the next phase of work for the Kapunda project.
“These in-situ lixiviant trials are a critical step in the assessment of the ISR process in
determining the copper solubility, hence recovery from the Kapunda copper
mineralisation,” Managing Director Nicole Galloway Warland said.
“This is a significant milestone for the Kapunda ISR Project, which Thor is delighted to
be a part of.”
Thor shares were trading grey at their previous closing price of 1.4 cents at 2:08 pm AEDT.
