Uranium was first discovered by Clem Walton and Norm McConachy in 1954, it was named after Norm's late wife Mary Kathleen. In 1955 British company Rio Tinto Mining formed Mary Kathleen Uranium Ltd and developed the mine and service town 6km away at a cost of A $24 million. 3,460 tonnes of uranium by the open-cut method was extracted and processed on site. By 1963 they finished ahead of schedule, and the mine was closed down and laid idle.
With the push for nuclear power a second life began in 1974 and a further 4,802 tonnes of uranium oxide was removed. A total of 31 million tonnes of ore was extracted and closed for good in 1982. The mine was 250 metres deep, four kilometres wide at the top, and 100 metres wide at the bottom.
Mary Kathleen became the site of Australia's first major rehabilitation project of an uranium mine, completed at the end of 1985 at a cost of A$19 million it was considered a success. In 1986, won an award from the Institution of Engineers Australia for environmental excellence and considered suitable for grazing. However, since rehabilitation, it has been found that the tailings repository at the Mary Kathleen site has been subject to seepage of radioactive waste causing widespread death of native vegetation.
There were approximately 1000 people living at the new township. At that time it comprised of Catholic church, schools, shopping centre, tennis courts, swimming pools, post office, cinema, sports ovals, banks and even a temporary hospital. The township expanded to approximately 1200 people before it was all closed down. It is sad when you look back at the old photos of the bustling thriving town and now look at what it has now become, just concrete slabs and memories of the past.
