Walbiri has an inferred resource of 7037 tonnes of equivalent uranium oxide at 641 parts per million, using a 200ppm cut-off.
The deposit had an earlier historical resource of 4789t uranium oxide, estimated in 1976.
Energy Metals said the resource made Walbiri the third-largest uranium deposit in the southern Northern Territory after Paladin Energy’s Angela deposit (13,980t) and the company’s own Bigrlyi deposit nearby (12,230t).
The company is looking into a joint development of Bigrlyi and Walbiri.
Small inferred resources were also announced for Bigrlyi satellite deposits.
The Sundberg deposit has a resource of 260t equivalent uranium oxide at 259ppm, while the Hill One deposit has a resource of 159t at 321ppm.
Energy Metals is confident of further growing resources in the area and will conduct additional drilling.
