Stage-1 production coming this year, stage-2 drilling begins North of 60 Mining News – February 19, 2021

On track to begin the initial phase of rare earth production at the Nechalacho project in Northwest Territories later this year, Vital Metals Ltd. has launched a drill program to prepare for the second stage of REE mining at the project along the shores of Thor Lake.
"2021 will be a groundbreaking year for Vital Metals," said Vital Metals Managing Director Geoff Atkins. "In addition to the commencement of development and construction activities for our Stage 1 operations at Nechalacho, the commencement of this drilling program marks the start of development activities for the larger stage-2 operation."
Nechalacho is a rare earths and critical metals enriched project that has been explored extensively by Canada-based Avalon Advanced Materials Inc. This work outlined near surface REE mineralization in the T-Zone and Tardiff zones, and the larger but deeper Basal zone.
Cheetah Resources Pty Ltd., a private Australian company acquired by Vital, paid C$5 million for ownership of the near surface resources at T-Zone and Tardiff.
Avalon retains ownership of the Basal zone, the subject of a 2013 feasibility study that considered a mine with the capacity to produce 9,286 metric tons of rare earths, 19,763 metric tons of zirconium, 2,231 metric tons of niobium and 243 metric tons of tantalum per year.
Vital, however, will be the first to mine rare earths and other critical elements from Nechalacho.
This mining is slated to begin this year at North T, a subzone that hosts 105,000 metric tons of resources averaging 8.9% (9,345 metric tons) total rare earth oxides.
Vital plans to use an ore sorting machine as a low cost and simple means to significantly upgrade the ore.
Utilizing x-ray transmission (XRT) technology, ore sorting tests upgraded Nechalacho material averaging 10.5% rare earth oxides to a rough concentrate averaging 36% REO, while retaining about 70% of the available rare earths.
This upgrade intermediary product will be upgraded at Vital’s rare earth extraction plant in Saskatchewan before being shipped to REEtec, a Norway-based company that has developed a completely new and game changing process for manufacturing high purity rare earths.
Earlier this month, Vital and REETec signed a definitive offtake and profit-sharing agreement for the production of 1,000 metric tons of rare earth oxides per year from concentrates shipped from Nechalacho and provides the option to increase the volume to 5,000 metric tons REO per year.
"The signing of this agreement will enable REEtec and Vital to work together to supply separated rare earth oxides, which are competitive to products produced anywhere else in the world into the electric vehicle and wind turbine markets," said Atkins.
More information on this agreement can be read at An international REE partnership in NWT in the February 3 edition of Metal Tech News. https://www.metaltechnews.com/story/2021/02/03/tech-bytes/an-international-ree-partnership-in-nwt/459.html.
With the initial feedstock coming from North-T, Vital is investigating the potential to expand production from Tardiff, a zone with 94.7 million metric tons of combined measured, indicated, and inferred resources averaging 1.46% (1.3 million metric tons) total rare earth oxides.
Tardiff, which lies above the Basal zone, also contains zircon and niobium grades that are comparable with other polymetallic rare earth projects.
While testing the lower Basal zone, Avalon drilled multiple holes fanned out from widely spaced drill pads. While this provided good coverage of Basal, the focus of Avalon's work, this strategy resulted in tight clusters of holes just below each pad at Tardiff.
To fill in and upgrade the resource between the pads, Vital plans to complete about 1,800 meters of drilling in 30 holes focused primarily on higher grade subzone of Tardiff with 3.2 million metric tons of resource averaging 2.4% REO. The company also plans to evaluate the expansion potential at T Zone with holes targeting South T and S, zones adjacent to the Nechalacho stage-1 pit at North T.
In addition to assays, the core will be used for metallurgical testing.
"The commencement of this drilling program marks the start of development activities for the larger stage-2 operation," said Atkins.
