Mount Weld — a new supply of dominantly light rare earths to the world!
Some historic, pre-JORC resource estimates exist for depositsat Ponton, Yangibana and in the east Kimberley region
Ambassador (Mulga Rock) uranium — 3% of projected revenue from by-product REE (dominantly La, Ce, Nd)
Western Australia has great exploration potential for REE in:Carbonatite and alkaline to peralkaline ringcomplexes
