WA1 Delivers Highest-Grade Niobium Hits Yet at Luni

15 May 2025 | Perth, WA – WA1 Resources (ASX:WA1) has announced some of its most exceptional niobium intercepts to date from ongoing resource definition drilling at its flagship Luni deposit, part of the West Arunta Project in Western Australia.

The latest assays from drilling across the southern and western zones confirm the presence of thick, high-grade niobium mineralisation, bolstering confidence ahead of an updated Mineral Resource estimate due in June.

Key intercepts include:

• 36.4m @ 4.9% Nb₂O₅ from 50m (LUDD-0121)

• 60.0m @ 3.2% Nb₂O₅ from 60.3m (LUDD-0124), including

  • 11.3m @ 12.7% Nb₂O₅

• 26.8m @ 4.9% Nb₂O₅ from 58m (LUDD-0125)

• 79.6m @ 2.1% Nb₂O₅ to end-of-hole (LUDD-0123)

Additional intercepts from RC and sonic drilling support the lateral and vertical continuity of mineralisation. Several holes also recorded elevated rare earth element (REE) values, including 11.3m @ 4.0% TREO, adding to the project’s multi-commodity appeal.

Managing Director Paul Savich said:

“These are some of the best results we’ve seen and show the Luni system extends well beyond our early development areas. With the final assays in, we’re now focused on updating our Mineral Resource and progressing pre-feasibility studies.”

WA1 has now completed over 60,000m of drilling at Luni, with three rigs active on site, supporting ongoing hydrogeological, geotechnical, and environmental studies. The updated MRE will include a maiden Indicated Resource, underpinning the company’s move toward development.
