WA1 Luni niobium project: open-pit and flowsheet takeaways for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
WA1 Resources has reported further high-grade infill drilling at the eastern zone of its Luni niobium project in Western Australia, including 7.3m at 2.9 per cent niobium pentoxide and 13m at 3.2 per cent. The results move the project closer to feasibility and strengthen the case for a standalone niobium operation with associated rare earths. For mine planners and metallurgists, the continuity of shallow, high-grade intersections supports potential for low-strip, open-pit designs and relatively simple concentrator flowsheets.
Technical Brief
- Infill drilling is concentrated in the eastern zone of the Luni carbonatite-hosted niobium system.
- New intersections also report associated rare earths, supporting a niobium–REE co-product development concept.
- Shallow mineralisation geometry in the eastern zone favours truck–shovel open-pit scheduling and short hauls.
- Consistent high grades across infill holes reduce resource classification uncertainty ahead of feasibility-level modelling.
- Denser drilling in the eastern zone will tighten variography and improve geostatistical confidence in grade continuity.
- Early confirmation of a standalone niobium project allows process engineers to focus on niobium-optimised concentrator design.
- Co-located rare earths may justify additional beneficiation stages or separate concentrate streams in the flowsheet.
- For similar mining projects, such infill campaigns are critical to de-risk strip ratio and pit optimisation.
Our Take
Across the 105 keyword‑matched pieces on niobium and rare earths in our database, Luni is one of the few Australian niobium projects consistently generating both high‑grade drilling and detailed metallurgical results, signalling it as a likely early domestic contender in a market otherwise dominated by overseas supply.
