EnviroGold Global achieves finance for Brisbane clean leach plant

Canadian company EnviroGold Global Limited has announced that it has closed the first tranche of financing to accelerate the establishment of its NVRO Clean Leach Process demonstration facility in Brisbane, Australia, to advance customer relationships and for general operating expenses.

In May the company entered into an agreement to purchase an integrated metal processing plant developed at the CSIRO’s Australian Minerals Research Centre in Perth, Western Australia.

The plant includes multiple cascading mixed acid leach tanks, a counter-current decantation (CCD) system, residue neutralisation and filtration, acid recovery and iron hydrolysis to enable production of magnetite co-product. The CCD system is used to separate post leach slurry from the fully encapsulated pipe reactor into pregnant leach solution and washed acid insoluble residue.

Originally developed by the CSIRO for research into the recovery of high-purity nickel and cobalt battery metals via solvent extraction, the plant is ideally suited, with minor modification, to demonstrate the NVRO Clean Leach Process at scale. The plant will be relocated and installed at the EnviroGold Clean Leach demonstration facility in Brisbane.

The plant is now surplus to CSIRO requirements, can process up to 15 tonnes per day of mine tailings, milled ore or smelter waste, and is ideal to showcase the NVRO Clean Leach Process on a small commercial scale with multiple customers already expressing interest to move from lab-scale to pilot-scale trials. The cost and time savings in acquiring a proven demonstration plant will significantly accelerate the EnviroGold market strategy.

“The procurement of the demonstration plant is coming together at a time of heightened interest in mine closure liabilities, tailings reprocessing and environmental remediation,” said EnviroGold CEO David Cam. “As demand for strategic and precious metals continues to increase, EnviroGold is now well positioned to accelerate the monetisation of its Clean Leach Process and leverage its expertise to expand its customer base.”
