Mary Kathleen, Queensland

Mary Kathleen was a mining settlement in the northwestern part of Queensland, Australia. It is located in the Selwyn Range between Mount Isa and Cloncurry.

Mary Kathleen was first settled during the 1860s. Uranium was first discovered at Mary Kathleen by Clem Walton and Norm McConachy in 1954: the deposit and the township was named after the late wife of McConachy. Prospecting and exploitation rights were subsequently onsold, and in 1955 Rio Tinto Mining formed Mary Kathleen Uranium Ltd to develop a mine and service town. An architect-designed town grew during 1956-58, with reticulated water from a dam, Lake Corella.
