Cummins Range Drill Results Show 28m at 116g/t Gallium Oxide
RareX Limited has reported new high-grade gallium re-assay results from 15 drill holes at its Cummins Range Project, confirming broad and consistent mineralisation alongside rare earths and scandium. These findings reinforce gallium’s potential as a valuable co-product in this multi-element critical minerals deposit.
- New gallium re-assays from 15 drill holes confirm wide, high-grade intervals
- Gallium mineralisation closely coincides with rare earth and scandium enrichment
- Significant intercepts include 28m at 116g/t Ga₂O₃ and 48m at 85g/t Ga₂O₃
- Ongoing metallurgical work aims to optimise gallium recovery alongside rare earths
- Cummins Range hosts a large resource with advancing mining lease application
Expanding Gallium Potential at Cummins Range
RareX Limited (ASX, REE) has unveiled further encouraging results from its ongoing gallium re-assay program at the Cummins Range Project in Western Australia's Kimberley region. The latest assays, drawn from 15 drill holes originally completed in 2020, reveal extensive intervals of high-grade gallium mineralisation that align closely with rare earth elements and scandium concentrations.
Among the standout intercepts are a 28-metre section grading 116 grams per tonne of gallium oxide (Ga₂O₃) starting at 53 metres depth, and a 48-metre interval at 85 grams per tonne Ga₂O₃ from near surface. These broad zones of mineralisation underscore the continuity and scale of the gallium-bearing system within the Rare Carbonatite Dyke, a key geological feature of the deposit.
Strategic Multi-Element Mineralisation
The Cummins Range deposit is already recognised for its significant rare earth oxides (TREO) and scandium content, with a mineral resource exceeding 500 million tonnes. The new gallium data enhances the project's profile as a polymetallic critical minerals asset, potentially adding a valuable revenue stream. CEO James Durrant highlighted the consistency of the gallium grades, noting that the data strengthens confidence in gallium as a parallel product alongside rare earths and phosphates.
Gallium’s association with rare earths in the regolith-hosted saprolite zone suggests that existing rare earth processing pathways could be adapted to recover gallium efficiently. This is a crucial consideration as RareX advances metallurgical testing with partners SGS Lakefield and GEGA Elements, aiming to optimise gallium deportment and extraction.
Building on a Robust Resource Base
The recent re-assays complement earlier high-grade gallium results reported throughout 2025, including intercepts such as 115 metres at 146 g/t Ga₂O₃ and 60 metres at 99 g/t Ga₂O₃. These consistent findings across multiple drill campaigns reinforce the geological model and support the ongoing resource development strategy.
RareX is progressing towards securing a mining lease for Cummins Range, with heritage agreements in place and a strong focus on integrating gallium into the project’s economic framework. The company’s broader portfolio also includes other critical mineral projects, positioning RareX as a notable player in Australia’s rare earth and critical metals sector.
Looking Ahead
While the gallium grades and intervals are promising, the economic viability of gallium recovery hinges on the outcomes of metallurgical studies and process optimisation. The company’s ongoing work will be pivotal in defining gallium’s role in the project’s future revenue mix and its contribution to the growing demand for critical minerals in advanced technologies.
Bottom Line?
RareX’s expanding gallium dataset at Cummins Range signals a compelling multi-element opportunity, with metallurgical results set to shape its commercial potential.
Questions in the middle?
- How will metallurgical test results influence gallium recovery economics?
- What is the timeline for mining lease approval and project development?
- Could gallium become a significant revenue contributor relative to rare earths?
