Mary Kathleen, Queensland
Mary Kathleen was first settled during the 1860s.
In 1954, a significant uranium deposit was discovered at the site (20.7470°S, 140.0123°E). Mary Kathleen Uranium Ltd. built a mine, with 4,080 tonnes of uranium oxide being extracted between 1958 and 1963. The mine then lay idle until 1974, when it was reopened. The second phase of production began in 1976 and the mine was finally closed down in 1982 after a further production of 4,802 tonnes of uranium oxide. A total of 31 million tonnes of ore were extracted from the mine until it was exhausted. Processing occurred on-site.
Mary Kathleen's uranium deposits originated from contact metasomatic processes. This type of occurrence is uncommon, with Mary Kathleen being the only commercial example. The uraninite here was conglomerated with garnet.
The former town of Mary Kathleen has a unique feat in Australian Sport. The former Australian Rules club (Mary Kathleen) won three consecutive premierships from 1977 to 1979 in the Mount Isa Australian Football League, and is one of the few clubs or towns for that matter to win Senior titles, and no longer be in existence as a club or any population in its locality.
The township, mine and mill were dismantled and the tailings rehabilitated by the end of 1984. The site, now only roads and concrete pads, can be accessed, as an overnight camp, from the Barkly Highway at -20.780837,139.9734. The land has since been rehabilitated and is now suitable for grazing.
