These tests are the final hydrometallurgical assessments before ECL commences Site Environmental Lixiviant Trials (SELT).\n \n \n \n \n \n The purpose of lixiviant trials, or 'push pull tests', is to assess the solubility of copper mineralisation, and therefore copper recovery, using a specially designed solution called a lixiviant under in-situ conditions. The trial is to be undertaken in two stages. The first stage involves injecting and extracting a tracer solution (Sodium Bromide - NaBr) from the same well to demonstrate hydraulic connectivity between wells and the environmental monitor well network. This is followed by injecting and extracting lixiviant from the same well to test copper solubility from the mineralisation.\n \n \n \n \n \n The trials are anticipated to take three to four weeks.\n \n \n \n \n \n Nicole Galloway Warland, Managing Director of Thor Mining, commented: \n \n \n \"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.\n \n \n \n \n \n This is a significant milestone for the Kapunda ISR Project, which Thor is delighted to be a part of.\n \n \n \n \n \n I would also like to congratulate and acknowledge the efforts of the ECL team on winning this year's award for Innovation and Collaboration in the Resources Sector by the Department of Energy and Mining, South Australia for the Kapunda Copper ISR Project.\"\n \n \n \n \n \n \n \n https://www.energymining.sa.gov.au/premiers_awards_in_energy_...
