In 1981 following a reassessment of the site, further rehabilitation was undertaken and included additional backfilling of old mine openings and covering of the tailings impoundment. At the same time, the site was also established as a repository for low-level radioactive waste materials, primarily to facilitate the clean up of contaminated soil held in Thebarton in the Adelaide metropolitan area.
The South Australian government's Mineral Resources Division has retained management responsibility of the site for the government, and maintains a continuing watch on the site with radiological advice and assistance from the Radiation Protection Division of the Environment Protection Agency (EPA).
The Mineral Resources Division is currently developing a long-term management strategy for the former site.
