Vital’s optimized MRE delivers 56% increase in Measured + Indicated resources for Tardiff rare earth deposit

Vital Metals Limited (ASX: VML) (“Vital”, “Vital Metals” or “the Company”) is pleased to report an updated Mineral Resource estimate (“MRE”) for the Tardiff Upper Zone (“Tardiff”), part of the Nechalacho Rare Earths Project (the “Project”), located in Northwest Territories (NWT), Canada.


Highlights:

  • New Tardiff MRE total resource tonnage (across all categories) of 192.7 million tonnes at 1.3% total rare earth oxide (TREO), containing 2.5Mt TREO.
  • Tardiff is estimated to contain 636,000 tonnes of NdPr (neodymium oxide + praseodymium oxide).
  • Incorporating all the latest drilling data this new estimate, compared to the April 2024 MRE, delivers:
    • 70% increase in reported tonnes in the Indicated Resource category;
    • 56% increase in reported tonnes in Measured + Indicated Resource categories;
    • 2% increase in contained NdPr;
    • Niobium (Nb2O5), hosted within the same geological formations hosting the rare earth mineralisation, reported for the first time.
  • Current MRE is reported above a 0.7% TREO cutoff grade instead of a metal equivalent value previously used.
  • Vital is using the updated Tardiff MRE as the basis for a Scoping Study to examine the size and scalability of future production scenarios. This is expected in the coming weeks.

The current MRE follows Vital’s completion of resource definition drilling program at Tardiff in 2023, totalling 74 holes for 6,664m, which returned high-grade results up to 8% TREO.

The current MRE features a total resource tonnage (across all categories) of 192.7Mt grading 1.3% TREO and 0.3% Nb2O5, containing 2.52Mt TREO including 636,000t of NdPr.

Vital Managing Director and CEO Lisa Riley said: “Our updated MRE for the Tardiff deposit shows increased confidence in the deposit, with a 70% increase in the Indicated Resource tonnages and a 56% increase in the Measured + Indicated Resource tonnages compared to our April 2024 historical MRE, while our Inferred Resource tonnages have decreased by more than 20%. While our overall totals of contained TREO and NdPr have only slightly increased on the April 2024 historical MRE, based on the drilling we completed in 2023, we now have more confidence that this is a truer representation of what this deposit holds.

“The current MRE is the final piece awaited for inclusion in our Tardiff Scoping Study, which is now due for delivery in the coming weeks.”

Vital VP Exploration Natalie Pietrzak-Renaud: “The positive changes to the current MRE compared to the April 2024 historical MRE is largely based on the inclusion of the 2023 drill results, the 2024 metallurgical test results we obtained from our 2023 collected composite Tardiff sample, and the carefully considered metrics we used as inputs. Our approach is to establish outputs that are realistic pathways for project development. With the work we completed on the MRE and the forthcoming Scoping Study, we have, and continue, to build a solid foundation of data and knowledge to advance our project.”

The Tardiff MRE is reported within an optimized open-pit shell using Studio NPVS from the Datamine Suite. The optimized pit shell was generated using a 45° maximum final pit wall, and a 150m RL lower pit limit.

Tardiff contains rare earth element (“REE”) and Niobium mineralisation hosted within a nepheline syenite intrusion. Recent metallurgical test work indicates strong potential to produce neodymium oxide (Nd2O3) and praseodymium oxide (Pr6O11), which are light rare earth oxides (LREO) with magnetic properties and are in demand due to their use in technologies such as high-strength magnets, aircraft engines, and various industrial and electronic applications. The recent metallurgical test work also indicates an opportunity to further investigate and advance the potential opportunity to recover niobium minerals from Tardiff ore. Niobium is in demand due to its low oxidation point and relatively high melting point. It is used as an alloy in aeronautic engines, electronic applications (due to its superconducting properties) and as an additive to lithium-ion batteries to enhance battery life.

The current MRE represents a significant increase in reported tonnes in the Indicated Mineral Resource category in comparison to the historical MRE completed in April 2024 and a decrease in reported tonnes in the Inferred Mineral Resource category. The current MRE is also reported above a 0.7% TREO cutoff grade instead of a metal equivalent value as previously used.

Wildfire Destroys Mining Camp in NWT, Former MP Slams Territorial Response

A fast-moving wildfire has destroyed the Nechalacho mining camp southeast of Yellowknife, Northwest Territories, erasing cabins and infrastructure at a rare earths project owned by Vital Metals (ASX:VML).

The blaze swept through the camp at Thor Lake on August 30 after strong winds carried it 16 kilometres overnight.

Vital Metals CEO Lisa Riley said the company believed the site was safe until conditions shifted suddenly. “And from one second to the next, it went from being relatively safe to being completely gone,” she told CBC.

Rare Earths Stocks: 9 Biggest Companies in 2025

Rare earth elements (REEs) are crucial for technologies like smartphone cameras and defense systems.

A select few from the group of 17 are also vital to clean energy transition industries such as electric vehicles (EVs) — neodymium and praseodymium are found in the permanent magnet synchronous motors used in EV drive trains.

The rare earths sector has been thrust back into the geopolitical spotlight as supply chains face mounting pressure from escalating US-China trade tensions and tightening global regulations.

In May 2024, the former US administration imposed a 25 percent tariff on Chinese rare earth magnets starting in 2026, marking the first time these components have been targeted under Section 301. The move hits sintered neodymium-iron-boron (NdFeB) magnets, vital for EVs and wind turbines, highlighting their strategic role in clean energy and defense.
