WA1 high-grade niobium at Luni: pit design and PFS insights for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
WA1 Resources has firmed up its model of high-grade niobium mineralisation at the Luni carbonatite in Western Australia, targeting an early mining window as its pre-feasibility study heads for completion in the December quarter. Recent drilling and testwork are refining the geometry and grade distribution of the core high-grade zone, supporting mine scheduling and pit design for an initial open pit development. Geotechnical and metallurgical data from these field activities will be critical for slope design, processing flowsheet selection and early capital estimates.
Technical Brief
- For similar mining projects, early integration of geotech and metallurgy at PFS stage typically de-risks capex estimates.
Our Take
Across our niobium keyword set, WA1 Resources’ Luni project in Western Australia is one of the few Australian niobium stories appearing repeatedly, signalling it as a likely reference asset for any future domestic niobium supply chain discussions.
