Send a message to oppose the Tivan mine in East Kimberley

    Dear Minister Swinbourn,

    Protect the Dunham River from the Speewah Fluorite Mine

    The proposed Speewah Fluorite Mine in the East Kimberley poses an unacceptable risk to one of the Kimberley’s most pristine river systems.

    Tivan Ltd’s proposed open-cut mine in the Speewah Valley is located right next to the Dunham River, a free-flowing waterway and vital tributary of the celebrated Ord River. The proposed development is enormous, with mine pits approximately 2km long, 180m wide and 105m deep, within a development footprint of 9,307 hectares.

    A major contamination risk

    The proposed mine poses serious risks to the East Kimberley’s environment, culture and future. Located beside the undisturbed Dunham River catchment, the mine could harm wildlife, traditional food sources and the downstream Ord River. 

    The mining could:

    • Pump contaminated pit water into the landscape: Tivan has proposed to inject contaminated water from the mining pit into the groundwater and/or directly into the Dunham River. Water in the mining pit is likely to contain elevated levels of fluoride, copper and other heavy metals which can harm animals in the river, human health and downstream wetlands.
    • Store toxic waste at the headwaters of the Dunham River: Thousands of tonnes of chemicals used in the processing plant will be transported into the East Kimberley for use on site, and 6.74 million tonnes of waste chemicals would be stored in a dam at the headwaters of the Dunham River. In the event of an extreme flood the dam’s spillway could overflow into the Dunham River. In a region with monsoonal rainfall and major flood events, a tailings dam failure or overflow would be catastrophic.
    • Deplete groundwater and change the Dunham’s natural flow: Even when there is no rain the Dunham River remains clean and healthy because it is fed by groundwater in the dry season. Tivan wants to extract 4.5 billion litres of groundwater per year. Extracting groundwater would disturb the flow regime of the river and potentially be harmful to animals that depend on a clean, healthy and flowing Dunham River.
    • Create long-term pollution: Although the mine would operate for only about 10 years, toxic mining waste could pollute rivers, groundwater and sediments for decades or even centuries. Clean, healthy and free-flowing rivers are vital to the future of the Kimberley, and its rivers should be protected.

    The Dunham River is a vital wildlife corridor supporting animals including the Gouldian Finch and Mertens’ Water Monitor, and important fish populations such as Barramundi and Black Bream. Its catchment also supports pastoral activities and provides important wet-season flows to the Ord River and the Ramsar-listed wetlands of Parry’s Lagoon.

    Any contamination of the Dunham could have negative impacts far beyond the mine site, affecting an interconnected river system and the communities and ecosystems that depend upon it.

    Damage to Country is inseparable from the wellbeing, culture and identity of its people.

    The potential for a catastrophe is too high.

    I call on:

    • Premier Roger Cook to protect the Dunham River and its catchment from the long-term risks of mining and contamination.

    • Environment Minister Matthew Swinbourn to reject the proposed Speewah Fluorite Mine.

    • Minister for Mines, Petroleum and Exploration and Water, Daniel Pastorelli to reject Tivan Ltd’s application for a water licence for the project and prohibit mining in the Dunham River catchment in perpetuity.

    Yours Sincerely,
