Announcement:
HRE URANIUM PROJECTS – EXPLORATION UPDATE
Heavy Rare Earths Limited (ASX: HRE) has released a March 2025 exploration update that signals progress across its uranium portfolio. With projects in the uranium-rich Curnamona Province of South Australia and the Mid West region of Western Australia, the company is moving aggressively to define targets through passive seismic, airborne surveys, and historical data analysis.
HRE Exploration Manager Joseph Ogierman alongside mine shaft at Bonython North uranium prospect, 5 kilometres north-east and along strike of historic Radium Hill mine, Radium Hill Project. This multi-faceted program is aimed at positioning HRE for drilling in late 2025 and early 2026.
Location Overview: Multi-State Targeting
The company’s uranium exploration program spans two states (Figure 1) :
South Australia: Lake Namba–Billeroo, Prospect Hill, Radium Hill
Western Australia: Perenjori project near the Mid West

Lake Namba–Billeroo and Prospect Hill Projects: Revisiting Forgotten Channels
HRE’s Lake Namba–Billeroo and Prospect Hill projects focus on palaeochannel-hosted uranium systems, a model well-known for its potential in sedimentary environments.
At Billeroo, passive seismic and gravity surveys now cover 35 km of palaeochannel length (Figure 2). These surveys revisit a zone last tested by a single drillhole in 1970.

Prospect Hill spans 9.5 km of exploration ground within a setting favourable for Tertiary and Cretaceous-age palaeochannels (Figure 3).

Previous drilling in the Namba Palaeochannel highlighted redox fronts and low-grade uranium anomalies. HRE is now interpreting historical drilling patterns to refine drill targets for the upcoming campaign (Figure 4).

Radium Hill Project: Breathing New Life into Australia’s First Uranium Mine
The Radium Hill project is steeped in uranium history, and HRE is now revisiting this classic district with modern tools and new objectives.
Key updates include:
Reconnaissance sampling at historic shafts and costeans
Assay testing of unsampled 1961 drill core from Bristowe’s Prospect, 1.1 km northeast of the main Radium Hill mine
Planned low-altitude airborne magnetic-radiometric survey along the projected northeast extension of the Radium Hill Line of Lode

This data compilation will inform structural and mineralogical interpretations to guide future drilling programs.
Perenjori Project (WA): Pre-Drilling Work Begins
The Perenjori project in Western Australia is progressing towards drill readiness. HRE has scheduled passive seismic surveys for March and is preparing for Ultrafine™ soil sampling across all three tenements (Figure 7).

All pre-drilling work is expected to be completed by mid-May 2025.
What Comes Next?
HRE is moving from early geophysical surveys to drill planning. Several key milestones are expected:
Processed geophysical data will be available in April 2025.
Assay results from the Radium Hill core are due in March 2025.
An airborne survey at Radium Hill is scheduled for late March 2025.
Drill targeting and approvals are planned for the second half of 2025 through early 2026.
Concluding Comments from Samso
This recent ASX release from Heavy Rare Earths Limited (ASX: HRE) is a clear indication that the company is now moving into the Uranium space and leaving behind the REE narrative. One of the positives of the uranium pathway compared to other commodities is that the future is to be created in Australia, or rather re-created.
There is no doubt in my mind that the future for Australia's solution to our energy crises is nuclear. The global path is towards nuclear and this will become clear in the near future. The path of renewable energy will move away form base load energy provider and nuclear will take its rightful place as the energy source that will feed cities. This is the economical path and only time will drag Australians towards this place.
From a company perspective, I have been waiting to see some real direction since the announcement of the Radium Hill acquisition in October 2024 (Acquisition of Three Highly Prospective SA Uranium Projects). The recent release does give us a good view of the direction.
Pros and Cons
Mineral exploration has a very difficult path to success and I am sure I am not telling any ASX investor anything new. The chances of success is in the sub 1% range and if we are opportunistic, we could extend that to a sub 5% range. The hard part for companies like HRE is to establish the existence of a potential to have an economic deposit in their tenements.
The Radium, Hill area has a history for something that may resemble an economic mineralisation and being in South Australia means if it exist, HRE can actually have a mining project. This is one battle won for HRE. Similarly for their Northern Territory project, in terms of the ability to make it a mining project.
I like Richard Brescianini and I think he is a realistic corporate participant. As I have repeatedly said, this is a very important aspect for retail investors. Retail investors, like Samso, are never the first to know the good or the bad news. To have a director that is balanced in his narration is a very important part for anyone interested in following the HRE story.
Looking at the projects I think HRE is a good inclusion in a watchlist but as we are all not going to live forever, we should keep our eyes wide open and our ears close to the ground for now.
