Announcement
Heavy Rare Earths Limited (ASX: HRE) continues to build momentum in Western Australia's Mid West, with the confirmation of a significant uranium target at its 100%-owned Perenjori Project. Following earlier geophysical and geochemical work, the latest soil assay results underscore the potential for a calcrete-hosted uranium deposit along the 8-kilometre Gingaba Well radiometric anomaly (Figure 1).

Samso has covered Heavy Rare Earths previously, particularly its Cowalinya rare earths project, but this latest update signals a deepening focus on uranium exploration, now targeting a geological setting with known regional analogues such as Yeelirrie and Lake Maitland.
🔷Key Highlights from the Soil Sampling Program
231 ultrafine soil samples collected, with field duplicates, targeting palaeochannel structures.
Uranium assays peaked at 116 ppm, confirming the airborne radiometric anomaly detected earlier.
The Gingaba Well anomaly, measuring approximately 8 km in length, exhibits strong spatial correlation with elevated soil uranium values, ranging between 11 to 138 ppm U.
Airborne U-channel response at Gingaba Well is higher than that observed at Toro Energy's Centipede/Millipede and Lake Maitland deposits.
A drill program is being planned, pending heritage and government approvals.

🔷The Bigger Picture at Gingaba Well
Gingaba Well represents a calcrete-hosted uranium target within a palaeochannel system (Figure 2)—a setting that bears similarities to deposits such as Langer Heinrich in Namibia and Cameco’s Yeelirrie in WA.

The favourable comparison of the airborne radiometric signal with known projects is notable: Gingaba Well's 26 ppm U response is about half that of Yeelirrie but notably stronger than Lake Maitland (15 ppm) and Centipede/Millipede (16 ppm) (Figure 3).

Moreover, while total rare earth assays ranged from 29 to 343 ppm across the survey area, no coherent REE anomalies emerged in this campaign. For now, uranium remains the focus, though the broader palaeochannel system may still yield rare earth insights in future programs.
🔷What’s Next?
Pending the necessary heritage and regulatory approvals, HRE is preparing to drill shallow fences of holes into the Gingaba Well uranium anomaly. These would be the first exploration drillholes on the Perenjori tenements.
The Company remains cautious yet optimistic that the surface anomaly could reflect a larger mineralised system below the palaeochannel. It’s a classic early-stage uranium exploration story—strong radiometric signature, matching soil assays, and structural support from passive seismic data.
Samso Concluding Comments
This is an interesting juncture for Heavy Rare Earths Limited. The confirmation of the Gingaba Well anomaly by soil assays adds substance to what was initially a promising radiometric signal. From an exploration standpoint, this ticks the early boxes—geophysical detection, geochemical validation, and a defined geological model.
It’s worth remembering that HRE is building this uranium narrative alongside its rare earths ambitions at Cowalinya. In that sense, the Perenjori Project broadens the company’s exposure across both energy-critical elements.
I think the next chapter—drilling—is the most important. It will give us a clearer picture of what lies beneath the palaeochannel. As always, results will do the talking, but this is the kind of technical progression we look for in a well-structured junior exploration company.
The demise of the REE market for small-cap mineral explorers has forced the hand of the company to seek other commodities. Uranium, in my opinion, is as good as it gets, but to be clear, this is still early-stage exploration. No drill holes have gone in yet, and until we see subsurface confirmation, the scale and grade remain speculative.
