Mary Kathleen

Mary Kathleen is an abandoned uranium mining town and open-cut mine site located about 55 km east of Mount Isa and 70 km west of Cloncurry on the Barkly Highway in north-west Queensland. Established in the 1950s to service the Mary Kathleen Uranium Mine, the fully planned town was dismantled after the mine closed in 1982. Today its concrete foundations, roads and pit lake remain as a well-preserved ghost town illustrating Australia's uranium mining history.

Visitors can expect an open, arid outback landscape with the remains of a planned 1950s mining town. Visible features include concrete slabs and foundations, former street layouts, scattered building remnants, and interpretive signage. The main feature is the large open-cut pit now filled with vivid blue water, viewable from a lookout. The site is unstaffed, exposed and quiet, with unsealed access roads and no commercial services.

Mary Kathleen Uranium Mine was discovered in 1954 and operated in two phases from 1958 to 1963 and 1976 to 1982, supplying uranium under contracts with the United Kingdom Atomic Energy Authority and later Japanese utilities. A complete town was constructed by Mary Kathleen Uranium Ltd to house workers and families, with housing, school, shops and services. At closure in late 1982 the town was sold and dismantled, leaving foundations and the rehabilitated open-cut pit as evidence of Australia's early uranium industry.

The site represents post-war resource development and the planned mining communities of outback Queensland. It is recognized as a heritage example of a purpose-built mining town and is a point of interest for understanding the social and industrial history of the Cloncurry region.
