Key Takeaways
- Heavy Rare Earths pivots to uranium exploration in South Australia.
- The company acquired Radium Hill, Lake Namba-Billeroo, and Prospect Hill.
- Projects neighbor major uranium producers Boss Energy and Heathgate.
- Early drilling planned in 2025 to build M&A interest.
- South Australia accounts for 80% of Australia’s uranium resources.
ASX junior pivots to South Australia uranium exploration as it acquires three projects near major producers, aiming to draw acquisition interest if drilling success materializes.
Heavy Rare Earths is placing a decisive bet on South Australia uranium exploration, repositioning its entire strategy around uranium assets in the Curnamona Province to attract potential buyers among established producers.
After facing challenges securing funding for its Western Australian rare earths ambitions, the company has moved aggressively into South Australia uranium exploration, acquiring Radium Hill, Lake Namba-Billeroo, and Prospect Hill. These projects are strategically located near operating mines owned by Heathgate Resources and Boss Energy.
“Our vision is clear: success in South Australia uranium exploration offers the most direct path to creating value, whether through developing these assets ourselves or positioning them for acquisition,” said Joseph Ogierman, Heavy Rare Earths’ exploration manager.
Proximity to Proven Production Drives South Australia Uranium Exploration Strategy
South Australia accounts for nearly 80% of Australia’s demonstrated uranium resources and close to a quarter of the world’s uranium supply. This makes the region an attractive target for any company focused on South Australia uranium exploration and low-cost production potential.

Radium Hill has historical significance as Australia’s first uranium-only mine, having produced 2.6 million pounds of uranium oxide between 1954 and 1961. Recent reconnaissance sampling by Heavy Rare Earths has revealed high-grade scandium and rare earth mineralization—underscoring the asset’s optionality beyond uranium.
Lake Namba-Billeroo and Prospect Hill, meanwhile, represent the company’s greenfield upside. Despite sitting within well-understood paleochannel systems, these tenements have not been tested by a single drill hole—a gap the company intends to close rapidly as it intensifies South Australia uranium exploration.
Major Uranium Projects in South Australia
| Project | Owner/Operator | Status | FY25 Production |
|---|---|---|---|
| Honeymoon | Boss Energy | Operating | 328,000 lbs |
| Beverly/Four Mile | Heathgate Resources | Operating | Not disclosed |
| Radium Hill | Heavy Rare Earths | Exploration | N/A |
| Lake Namba-Billeroo | Heavy Rare Earths | Exploration | N/A |
| Prospect Hill | Heavy Rare Earths | Exploration | N/A |
South Australia Uranium Exploration Supports M&A Ambitions
Boss Energy, which operates the Honeymoon mine nearby, recently produced 328,000 pounds of yellowcake in the June quarter, achieving its fiscal 2025 production target. Heathgate Resources, Australia’s largest ISR uranium producer, continues to expand operations at Beverly/Four Mile.
“Our Prospect Hill project is almost entirely surrounded by Heathgate,” Ogierman said. “In the event of successful South Australia uranium exploration, it’s logical to expect interest from producers already active in the basin.”
Analysts point out that as uranium prices hover near decade highs, companies with established infrastructure are seeking bolt-on acquisitions to secure long-term feedstock. Heavy Rare Earths’ ability to deliver credible drill results could catalyze that process.
Building a Pipeline of Targets Through South Australia Uranium Exploration
Since acquiring the tenements, Heavy Rare Earths has completed airborne magnetic and radiometric surveys at Radium Hill and passive seismic surveys across Billeroo and Prospect Hill. The data is now being integrated with open-file geological information to rank drill targets for the second half of 2025.
“Our near-term priority is to deliver a robust pipeline of targets,” Ogierman said. “Everything we’re doing in South Australia uranium exploration is designed to create optionality for the company and to demonstrate that this ground has the scale and potential to attract consolidation.”
In parallel, Heavy Rare Earths is engaging with Native Title groups and local landholders to secure access agreements and cultural heritage approvals.
Risks and Outlook
While the company’s strategy is compelling, the risks inherent in early-stage South Australia uranium exploration remain considerable. Neither Lake Namba-Billeroo nor Prospect Hill has been drill tested, and any success will require proving continuity of mineralization comparable to existing ISR deposits.
Yet with a footprint in one of the world’s most prolific uranium provinces and a clear focus on becoming an M&A target, Heavy Rare Earths is positioning itself for transformation.
“If you want exposure to South Australia uranium exploration, it’s hard to find a purer play than this,” said an Adelaide-based consultant who advises uranium producers on acquisitions.
For now, the company’s plan hinges on executing its first drilling campaign—and turning promising geophysical anomalies into hard evidence.
