Heavy Rare Earths Limited has completed acquisition of full mineral rights at its Prospect Hill Tin Project, setting the stage for a maiden resource estimate at the promising South Ridge prospect. Concurrently, the company advances uranium exploration across South Australia while strengthening its board.
- Completed acquisition of all mineral rights at Prospect Hill Tin Project
- South Ridge prospect shows strong tin assay results, enabling fast-tracked maiden resource estimate
- Geophysical surveys guide upcoming drilling programs at uranium projects in Prospect Hill, Radium Hill, and Lake Namba-Billeroo
- Bulk sample metallurgical testwork underway for Radium Hill mineralisation
- Board strengthened with appointment of Dr Amanda Buckingham and election of Gabriel Chiappini as Chairman
Prospect Hill Acquisition and Tin Potential
Heavy Rare Earths Limited (ASX, HRE) marked a significant milestone in its September 2025 quarter by finalising the acquisition of all mineral rights to the Prospect Hill Tin Project in South Australia. This project, the largest and most advanced tin prospect in the state, includes the South Ridge prospect where historical drilling has revealed encouraging tin grades, such as 3 meters at 4.85% tin and 5 meters at 3.32% tin. The company is consolidating extensive legacy data to expedite a maiden mineral resource estimate, aiming to quickly capitalise on this critical mineral asset amid growing global demand.
Advancing Uranium Exploration Across South Australia
Alongside tin, Heavy Rare Earths is progressing uranium exploration at multiple sites. At Prospect Hill’s Wattleowie Valley, integrated passive seismic and gravity surveys have been combined with regional geophysical data to identify groundwater pathways potentially enriched with uranium. Similar geophysical work at Radium Hill and Lake Namba-Billeroo is refining drill targets, with heritage clearances underway to facilitate maiden drilling campaigns. Notably, Radium Hill holds historical uranium production and the company is conducting metallurgical testwork on bulk davidite ore samples to assess processing viability.
Strategic Board Enhancements
In a move to bolster its exploration and development strategy, Heavy Rare Earths appointed Dr Amanda Buckingham, a seasoned geophysicist and CEO of Warriedar Resources, as a Non-Executive Director. Additionally, Gabriel Chiappini, a chartered accountant with extensive capital markets and governance experience, was elected Non-Executive Chairman. These appointments follow the retirement of former Chair John Byrne, whose tenure saw the company’s portfolio expansion and project advancement.
Financial Position and Outlook
Financially, the company reported a net cash outflow of AUD 278,000 for the quarter, with cash reserves standing at AUD 1.657 million. This liquidity position supports ongoing exploration activities and the planned drilling programs. Heavy Rare Earths’ focus on critical minerals like tin, uranium, and rare earth elements aligns with global supply chain priorities, potentially positioning the company to benefit from increasing demand and supportive government policies.
Overall, Heavy Rare Earths is transitioning from data consolidation and survey interpretation to active resource definition and metallurgical validation, setting a foundation for value creation in the near term.
Bottom Line?
Heavy Rare Earths is poised to translate its extensive South Australian exploration groundwork into tangible resource milestones, with market eyes on upcoming drilling results and maiden resource estimates.
Questions in the middle?
- When will Heavy Rare Earths release the maiden mineral resource estimate for the South Ridge tin prospect?
- What are the expected timelines and targets for the maiden drilling programs at Prospect Hill uranium and Radium Hill projects?
- How will metallurgical testwork outcomes at Radium Hill influence the project's development potential?
