Alligator River Project

The Project is the largest granted tenement package in the Alligator River Uranium Province, one of the top three uranium districts in the world.

In March 2018 Vimy acquired the Alligator River Project in Arnhem Land, Northern Territory from Cameco Australia Pty Ltd.

The tenements are on Aboriginal land vested in the Arnhem Land Aboriginal Land Trust and managed by the Northern Land Council on behalf of the Traditional Landowners.  Deeds of Agreement exist for all granted tenure covering exploration activity along with commercial terms and conditions for future mining activity, which ensures that the environment will be protected and that Traditional Landowners and local Aboriginal Communities will benefit from Royalties and jobs. 

The Alligator River Project comprises three separate tenement packages covering a total area of 3,865km2 including 1,600km2 of granted exploration licences. 


King River-Wellington Range project (1,675km2)

The King River-Wellington Range project has 1,600km2 of granted tenure. The ground hosts the Angularli deposit, as well as a large number of highly prospective targets, at different stages of exploration.

In March 2018 Vimy also announced the Maiden Mineral Resource at the Angularli Deposit, the most advanced of the many prospects in the King River-Wellington Range project.

About the Alligator River Uranium Province

The Alligator River Uranium Province is a world-class uranium province.  The deposits in the Province are unconformity style that is unique to both the Alligator River and the Athabasca Basin in Canada. These deposits are noted for their large size and exceptional grades including some of the largest deposits in the world. 

The Alligator River uranium province has a proven exploration track record with over 750Mlbs U3O8 in mineral resources (current and mined) and has produced a total of 312Mlbs of uranium over the past 65 years. 

During Australia’s Three Mine Policy (1984-1996) however all exploration licences in the area were held in moratorium which resulted in limited exploration. 

The diagram below shows the huge deposits that were discovered in the Athabasca region during the same time and highlights the potential for similar discoveries at the Alligator River Project.

Ore Sorting Results at the Angularli deposit

In September 2020 Vimy announced the results of an ore sorting trial on a composite of mineralised material from the Angularli deposit at Alligator River.  The results of the test, which was carried out by leading sorting systems supplier TOMRA, highlight the potential of ore sorting to lower project costs and improve the Project’s potential economics.

Data from the trial was collected using TOMRA’s COM X-Ray transmission (XRT) Tertiary system, which uses a broad-band electrical X-ray source.
