Located 22 km north of the Ranger mine, adjacent to the Magela Creek. Discovered in 1970 by Queensland Mines. Purchased in 1991 by Energy Resources of Australia Ltd (ERA). Uranium reserves of 205,000 tons at an average of 8 pounds uranium oxide per ton. Mining plans are however very controversial.

Jabiluka is one of the world's larger known uranium deposits, with reserves containing 71,000 tonnes of U3O8. The Jabiluka lease abuts the Ranger mining lease so subject to relevant approvals, the ore from Jabiluka could be processed to U3O8 at the Ranger mill.
In late 2003, the backfilling of the 1.2 kilometre decline at Jabiluka was completed, with mineralised and non-mineralised rock returned to the underground workings (http://www.energyres.com.au/our_business/jabiluka).
In early 2005, an agreement on the long-term management of the Jabiluka lease area in the Northern Territory was signed by the Mirarr Gundjeihmi Aboriginal people, Energy Resources of Australia (ERA) and the Northern Land Council (NLC). The agreement obliges ERA (and its successors) to secure Mirarr consent prior to any future mining development of uranium deposits at Jabiluka (http://www.energyres.com.au/our_business/jabiluka).

There is also an unidentified Bi telluride present.

Geochronology

Mineralization age: Mesoproterozoic : 1437 ± 40 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
