The Mulga Rock Uranium Project (MRUP) is located near Kalgoorlie in the Great Victoria Desert, Australia. Containing the country’s biggest undeveloped uranium resources, the project is 100% owned and operated by Vimy Resources and is located near Kalgoorlie in the Great Victoria Desert, Australia. is 100% owned and operated by Vimy Resources. The Mulga Rock Management Plan has been approved (more).
The pre-feasibility study was completed in November 2015, while the definitive feasibility study for the project was initiated in February 2016. Western Australia’s Environmental Protection Authority approved the project for implementation in August 2016. The mine is estimated to produce 1,360t of uranium-oxide a year over its estimated mine life of 16 years. Its development is expected to create 490 new jobs in Western Australia.
Mulga Rock Uranium Project Geology and Mineralization
The mine includes four main polymetallic deposits, including Princess and Ambassador in the Mulga Rock East (MRE) mining center, and Emperor and Shogun in the Mulga Rock West (MRW) mining center. Of the four, the Ambassador deposit is the biggest, flat-lying deposit that stretches over 9km.
The deposits occur in cretaceous to late-eocene carbonaceous sediments containing uranium and base metal. Minerals in these deposits appear as fine-grained sands, silts and clays within strongly oxidised carbonaceous sediments.
Reserves at Vimy Resources’ Uranium Project
As of June 2016, the four deposits at Mulga Rock project were estimated to hold combined indicated and inferred resources of 66.6Mt at 520ppm U3O8, containing 76.2 million pounds (Mlb) of U3O8.
Mining and Processing at the Mulga Rock Mine
Open-cut mining using both conventional truck and shovel method and mechanized strip mining techniques will be deployed at the Mulga Rock project. The mine is expected to yield 4.5Mt of ore a year and produce 1,360t of uranium oxide concentrate (UOC) a year, on an average, over its life time.
