Stop Tivan mining in the Dunham River!
The Dunham River in the East Kimberley is a pristine, free-flowing river that rises between the Durack and O'Donnell ranges, flowing through the stunning Speewah Valley before joining the Ord River. In the wet season the Dunham provides huge flows to the Ord River and into Cambridge Gulf. During the dry season the river is fed by groundwater, and becomes a refuge for Gouldian Finches, Mertens’ Water Monitors, Barramundi, Black Bream and other Kimberley wildlife that depend on a clean, fresh, and flowing river. For Traditional Owner Sally Martin, Speewah valley has been part of her history for many generations, “It’s a place I’m always in awe of. It’s tranquility and it’s a place of peace.”
But the future of this pristine river system and the entire East Kimberley hangs in the balance.

Traditional Owners are deeply concerned about a current proposal to mine for critical minerals right next to the Dunham River. Tivan Ltd has proposed to extract 8.4 million tonnes of fluorite ore from an open-cut mine located immediately alongside the river. The company proposes to process the ore on site using thousands of tonnes of chemicals, with 6.74 million tonnes of toxic waste to be stored in a tailings dam at the very top of the river catchment. The region is prone to extreme wet-season flooding, creating a serious risk that waste could enter the Dunham River through dam failure or overtopping.
Tivan has also proposed pumping water from the mine pit back into the landscape, potentially discharging billions of litres of contaminated pit water into the Dunham River over the life of the mine.
The risks to the Dunham River, its wildlife, downstream communities and businesses along the wider Ord River system are unacceptable. Environs Kimberley are calling on you to help protect the Dunham, so that Kimberley Rivers stay clean, healthy and safe for generations to come.
Join us in urgently calling on the WA Premier Roger Cook, Environment Minister Matthew Swinbourn and Minister for Mines, Petroleum and Exploration, and Water Daniel Pastorelli to reject Tivan Ltd’s mining application.
