Vital’s Metallurgical Testwork at Tardiff Returns Positive Results for Stage 2 Operations
22 June 2021
Highlights
- Vital plans to mine the Tardiff Zone at Nechalacho in Stage 2 operations, creating a larger scale, longer life rare earths project
- Metallurgical testwork on ore from Tardiff Zone at Nechalacho shows potential to use similar process flowsheet as ore mined from North T Zone
- Testwork shows potential to incorporate additional processes, including gravity and flotation separation in Stage 2 to achieve a high-grade (>35% TREO) rare earth concentrate
- Using Stage 1 process in Stage 2 will reduce capital costs and de-risk the Project
- Vital Metals to become Canada’s first rare earths producer with rare earths production from Stage 1 at Nechalacho on track to commence this month via ore sorting.
Vital Metals Limited (ASX: VML) (“Vital”, “Vital Metals” or “the Company”) is pleased to announce positive results from metallurgical testwork completed on samples from the Tardiff zone at Vital’s Nechalacho rare earths project in Canada.
Vital Metals’ Managing Director Geoff Atkins said the Tardiff metallurgical testwork demonstrated the potential to continue a similar process flowsheet in Stage 2, with the introduction of an additional beneficiation process due to the finer nature of rare earth mineralisation at Tardiff. “The testwork program achieved results which were better than expected and indicates that we will be able to utilise the same process from Stage 1 at Nechalacho in Stage 2, with the addition of an additional beneficiation step, such as a flotation plant. Achieving this will greatly reduce capital costs and risk,” he said.
“As expected, due to the finer grain sizes at Tardiff than at North T, the testwork has indicated that an additional process step, will likely be required to achieve the required feed grade into the kiln. Flotation showed great promise in terms of high REO grade, low mass pull and reasonable REO recovery.”
“The ability to utilise plant and equipment from the Stage 1 – North T operation in Stage 2 is critical to achieving our target of funding the development of the Tardiff Zone out of Stage 1 operating revenue.”
