Beverley Uranium Mine
Encyclopedia
The Beverley Mine is Australia
's third uranium mine and Australia's first operating in-situ recovery
mine. It is located 35 km from Lake Frome
at the northern end of the Flinders Ranges
in South Australia
and opened in 2001. Beverley Uranium Mine was discovered by one of Bill Siller's companies and was named after his wife—Beverley Siller.
Beverley is a paleaochannel uranium deposit. The uranium mineralisation (mainly coffinite
) is hosted by loose sands in the channel of a former river. The ore bearing horizon is now at a depth of about 100 to 150m. The deposit is estimated to contain 21,000 tonnes of uranium oxide
for a mine life of 15 to 30 years. Uranium is extracted by in-situ leaching, involving the injection of a fluid containg sulphuric acid and hydrogen peroxide into the ore-bearing permeable horizon to mobilise the uranium. The fluid is then recovered and uranium is extracted at a central plant using ion-exchange. The final concentrate is trucked to Port Adelaide
and then shipped to oversea customers.
In August 2008, federal approval was given to Heathgate Resources for a greater area to be accessed for mining in order that the pre-approved volume of material could be extracted from the mine.
Between 1998 and 2007, Heathgate reported 57 spill incidents to Primary Industries and Resources South Australia (PIRSA).
In 2005, the Four Mile
uranium deposit was discovered a few kilometres north-west of Beverley. The deposit is owned by Quasar Resources, (a 100% subsidiary of Heathgate), and Alliance Resources. Development of the deposit was approved in 2009. It is planned to do the final uranium extraction and concentrate production for Four Mile at the Beverley Plant.
The mine borders on the protected Arkaroola Wilderness Sanctuary
that has also been subjected to uranium mining. Following unprecedented public pressure, the South Australian government announced on 22 July 2011 that steps would be taken to ban mining and exploration in Arkaroola.
