The Federal Government has approved funding to study ways to increase water storage for the Lindenow Valley, including the potential for a water storage facility using part of the mining void from the proposed Fingerboards Mineral Sands Project.
Kalbar Resources’ Executive Chairman, Robert Bishop, said, ‘A mineral sands mine doesn’t normally leave a hole behind and is progressively rehabilitated as the mine moves through the orebody. However, we are proposing to leave a portion unfilled to create a large multi-user water storage facility.”
Using the mining void could be an economic option to help with water security in the Lindenow region. Earthmoving is usually the greatest expense in building water storage, so using the mining void would greatly reduce the total cost. Additionally, the clay that is required to make the facility watertight is abundant in the overburden of the mine, reducing cost even further.
Mr Bishop said, “We understand that water security is a critical issue for the Mitchell Valley producers. Initial indications suggest demand may be around 8-10Gl but the water storage facility can be scaled as required.”
Deputy Prime Minister and Minister for Agriculture and Water Resources, Barnaby Joyce announced $554,400 to fast-track the Lindenow Valley water security feasibility study as part of the Federal Government’s commitment to developing water infrastructure.
