Newmont hit with class action over ‘toxic trifecta’ claims at Cadia
Landowners in NSW have filed an environmental class action against Cadia Holdings, a subsidiary of Newmont, alleging they have been exposed to pollution from the Cadia mine.Filed by William Roberts Lawyers, the claim alleges pollutants detected on private properties include arsenic, heavy metals and the “forever chemical” PFAS.The lawyers say residents have reported visible contamination in waterways around the mine since around 2024, including the Belubula River, with laboratory testing allegedly showing heavy metals, PFAS and hydrocarbons accumulating in “highly toxic foam”.The claim alleges the chemicals are linked to Cadia’s ore processing and tailings deposited in an open cut pit after the 2018 tailings dam wall collapse.The plaintiffs are seeking compensation, including damages for alleged reductions in property values, and an injunction to restrain further pollution.This isn’t the first time environmental concerns at Cadia have been raised.Community members have previously reported clouds of white dust blowing from tailings facilities, while mining dust from crushing operations at the Cadia East underground mine has also been raised as a concern.Cadia Holdings was ordered to pay more than $400,000 after being prosecuted by the NSW Environment Protection Authority (EPA) for three dust emission offences that occurred between November 2021 and May 2023.William Roberts principal lawyer Oliver Gayner, who previously worked on the $212.5m Federal Court settlement of PFAS-contaminated communities including Williamtown, is acting for the plaintiffs.“For several years the Cadia residents have repeatedly raised their concerns about the detrimental environmental impact caused by this mine,” Mr Gayner said.“They have provided scientific evidence to Newmont and the EPA, but their concerns have not been addressed.“That is why the community are now taking this class action as a last resort. They do not want to close the mine – instead they seek what they were promised, which is a safe and sustainable mine which acts as a good neighbour.”Newmont Cadia confirmed that it had been served with proceedings in the Supreme Court of NSW.“Cadia will respond through the appropriate legal processes. As the matter is before Court, it is not appropriate to comment further at this time,” Newmont said in a statement.“Newmont takes its legal and regulatory obligations seriously and is committed to environmental stewardship.”While Cadia is currently approved to continue operations until 2031, Newmont is seeking approval from the NSW and Federal governments to extend its mining operations for about 25 years.Extending mining beyond 2031 will provide ongoing employment for more than 1500 people, 80% who live locally in Orange, Blayney and Cabonne, according to Newmont.
