ASX / Media Announcement 3 August 2021
Vital intersects high-grade REO in Tardiff Zones 2 & 3 including outside existing resource at Nechalacho
Highlights
-
Vital completed 10 holes across Tardiff Zones 2 and 3 to define a Stage 2 Mine Plan for Nechalacho rare earths project in Canada, with all holes hitting extensive mineralisation
-
Drilling at Tardiff Zones 2 and 3 intersected thick zones with total rare earth oxides grades above 2% TREO
-
Best results from Zone 2 from the 5 drill holes include:
-
25.1m at 3.03% TREO
-
19.0m at 2.05% TREO
-
All Zone 2 intersections are within 75m of surface with the best results in the western most drill holes, indicating high-grade TREO is open to the west
-
Zone 2 high-grade TREO intercepts are outside the Upper Zone Mineral Resource, indicating potential for an additional high-grade TREO resource in the Tardiff area
-
The remaining 5 holes drilled at Zone 3 also hit shallow, high grade REO intersections
-
Best results from Zone 3 include:
-
51.0m at 2.13% TREO
-
36.7m at 1.96% TREO
-
All 5 holes drilled in Zone 3 confirmed the high grades previously encountered with highgrade mineralisation open in all directions
-
With high grade mineralisation remaining open at all zones, Vital will undertake additional drilling at Tardiff to delineate the boundaries of the three Tardiff high-grade zones in addition to identifying the relationships between the zones, including whether they are in fact connected.
-
Previously announced metallurigcal results from Tardiff indicate that this bastnaesite mineralision can be processed through the same plant being constructed to process North T ore.
Vital Metals Ltd (ASX:VML) ( “Vital”, “ Vital Metals ” or “ the Company ”) is pleased to announce it has received outstanding first-pass assay results from the Tardiff Zones 2 and 3 within its 100%-owned Nechalacho Rare Earth Project, Northwest Territories, Canada. The results have added potential to extend the mine life of the Nechalacho project significantly, with further drilling needed to better define the Tardiff zones, which remain open in all directions.
Vital is commencing Stage 1 rare earth production at Nechalacho via ore sorting, with plans to mine the North T deposit in Stage 1. Stage 2 will focus on the Tardiff deposit, where it anticipates building a large-scale, long life rare earth mining and processing operation.
Vital Metals Managing Director Geoff Atkins said , “Drilling results from Tardiff Zones 2 and 3 have shown the potential for Nechalacho to be a much larger rare earths operation than we anticipated. We completed the drilling at Tardiff as part of defining a Mine Plan for Stage 2 operations at Nechalacho, which will initially focus on Tardiff Zone 1, but with the results showing mineralisation in both Zone 2 and 3 remaining open, we will plan further drilling in these areas over the next year to get a better understanding of the mineralisation and determine if the three zones are connected.“
“Our recent metallurgical test work, reported in recent weeks, showing material from Tardiff Zone 1 was amenable to a similar process flowsheet, with an additional beneficiation step such as flotation, to that being utilised at North T, has given us great confidence for the potential of Nechalacho to be built into a large-scale, long-life rare earths operation. We will complete further metallurgical testwork Tardiff Zones 1 material to define a process flowsheet to provide further clarity on the scope of Stage 2.”
“With the commencement of production at Nechalcho, we are excited about the future of this project, which continues to grow in potential and is turning into one of the worlds best light rare earth projects.”
The Nechalacho rare earth project consists of two distinct deposits which Vital will develop over two stages. The North T deposit hosts a high-grade resource of 101,000 tonnes at 9.01% LREO[1] in the measured and indicated JORC 2012 categories, making it one of the highest grade rare earth deposits in the world. Development of this deposit in currently underway under Stage 1. The second deposit, the Upper Zone where the Tardiff Zones are located, boasts an impressive light rare earth oxides (LREO) resource of 94.7 million tonnes at 1.46% TREO[2] in the measured, indicated and inferred JORC 2012 categories and will be the focus of expanded operations in Stage 2.
Vital’s drilling program targeted three high-grade REO zones previously identified in wide-spaced historic drilling by Avalon Materials Inc and its predecessors. These zones are known as Tardiff Zones 1, 2 and 3.
Tardiff Zones 1 and 3 were drilled on a close spacing (25m x 25m) to enable their resource confidence levels to be upgraded so mining and processing studies can be carried out on these zones. The drilling at Tardiff Zone 2 was designed to get a better understanding of high-grade REO mineralisation that is not currently in the resource estimation released in 2019. All drill holes were drilled to a maximum depth of 72m vertical.

Tardiff Zone 2
Vital drilled five drill holes at Tardiff Zone 2 to investigate high-grade REO mineralisation indentified by drill holes drilled in the 1980s with minor follow-up by Avalon in 2013. The 1980s drilling returned high-grade assays but Vital’s experience of REO assaying at Nechalacho in the 1980s found it was not accurate for resource estimation. REO assaying of the 1980s drill holes was sporadic and much of the core had not been assayed for TREO where high zirconium grades indicate high-grade REO would have been in the core. Vital decided to position five holes to get an understanding of the thickness and grade of the REO mineralisation in the Tardiff Zone 2 area.

Figure 4 – Section at Tardiff 2
All five holes drilled at Tardiff Zone 2 successfully intersected the REO mineralisation and demonstrated similar grades and intercept lengths to nearby historic drill holes. Pleasingly, holes L21269 and L21-570 on the western side shows the high-grade REO mineralisation is open to the west and appears to be getting thicker and higher grade to the west. The 2021 drilling has shown there is potential for a significant high grade REO resource in the Tardiff Zone 2 area and further drilling is required to delineated the size and grade of this zone of mineralisation.
Tardiff Zone 2 intersections are shown in the following table.

Tardiff Zone 3
Historical drill holes from drilling programs by Avalon Materials Inc between 2007 and 2013 targeted the heavy rare earth rich Basal Zone (below the Vital Metals owned Upper Zone). The targeting of the Basal Zone resulted in very poor definition of the Upper Zone as many of the holes were drilled as fans from a single drill pad. One of these fans of five holes delineated a high-grade zone of REO mineralisation near the surface. As the fan of five holes were drilled from one drill pad, the high-grade mineralisation was only defined over a small area of 25m by 30m and it was unknown if the high grades extended beyond this small area.
Vital completed five holes to the north, south and west of the historic fan of holes aiming to increase the size of the high-grade zone and understand the extent and orientation of the high-grade zone.

Figure 6 – Section at Tardiff Zone 3
All five drill holes at Tardiff Zone 3 all successfully intersected the higher grade REO mineralisation, with the high-grade mineralisation open in all directions. It appears as though the high-grade zone strike is in an east-west direction and dips to the south. Vital will plan further drilling to better understand the potential of this zone of high-grade mineralisation.

Conclusions and Next Steps
Results for the Tardiff Zone 1,2 and 3 drilling program demonstrate that broad high grade zones of significant tonnages are present within the larger Upper Zone, with the previous drilling programs undertaken by Avalon being too wide to delineate these zones and their extent. In addition, the drilling program undertaken at Tardiff Zone 2 indicates the potential for a significant high grade resource which is not currently contained within the Mineral Resource estimate.
Following the positive nature of these results, coupled with the results achieved from the scouting metallurgical testwork program previously announced (refer ASX announcement 23[rd] June 2021), Vital will now proceed to define a mining and processing operation at Tardiff, which will commence utilising Tardiff Zone 1 ore before expanding into Zones 2 and 3.
As part of this program, Vital will undertake further drilling for all three of the Tardiff Zones. The goals of this program will be to delineate the boundaries of the three Tardiff high-grade zones in addition to identifying the relationships between the zones, including whether they are in fact connected. Further with a number of holes ending in high grade mineralisation, the future drill program will test the full depth of the high grade zones. Vital expects this drilling to commence during the northern winter.
