Arafura is developing the Nolans Neodymium Praseodymium Project in the Northern Territory.
The company is undertaking a definitive feasibility study (DFS) which is due in early February 2019 and recently announced an optimisation review of the DFS’ cost estimates.
Nolans has a JORC resource of 56 million tonnes at an average grade of 2.6% total rare earth oxides (TREO) that extends 215 metres below surface.
The resource has the potential to support mining and processing operations for at least 30 years, at a design capacity of 14,000 tonnes of TREO equivalent a year.
Arafura’s focus during the year has been to validate the performance of its process flowsheet through completing seven consecutive pilot operations.
Last week the company announced it had completed phase five of pilot operations.
