Highlights

  • Heavy Rare Earths to secure majority stake in Prospect Hill tin project
  • Agreement strengthens critical minerals and clean energy asset portfolio
  • Joint venture planned after exploration milestones are achieved

Heavy Rare Earths (ASX:HRE) has moved to significantly broaden its presence in Australia’s critical minerals landscape by entering into an agreement to acquire a major interest in the Prospect Hill tin project. Located in the Northern Flinders Ranges, this site is recognised as one of South Australia’s largest and most advanced tin developments.

The strategic move aligns with the company’s vision of building a diversified portfolio that complements its existing scandium and rare earths opportunities at the Radium Hill uranium project. While the company is not part of the top ASX100, its latest step underscores a commitment to developing assets linked to clean energy and strategic resources.

Strengthening Mineral Rights

The deal with Havilah Resources (ASX:HAV) extends Heavy Rare Earths’ existing mineral entitlements beyond uranium to encompass all minerals, including tin. Historical exploration data reveals notable tin mineralisation at the South Ridge prospect, supported by earlier drilling and metallurgical studies indicating the presence of cassiterite suitable for gravity-based processing.

Under the agreement’s terms, Heavy Rare Earths will undertake targeted exploration work, focusing on drilling and advanced geological studies. Upon meeting agreed milestones, the partnership will evolve into a joint venture structure, offering both parties a pathway toward potential development.

Unlocking Prospect Hill’s Value

Prospect Hill’s appeal lies in its rich history of exploration, coupled with its strategic location in a region known for hosting high-value mineral deposits. The upcoming drilling programs aim to better define the mineral resource and obtain samples for metallurgical testing. This data will help shape future project planning, with an emphasis on the responsible extraction of tin and other key minerals.

Building a Broader Critical Minerals Portfolio

This latest acquisition complements Heavy Rare Earths’ earlier transaction with Havilah, which brought uranium and critical minerals prospects in the Curnamona province under its control. These include extensions of known mineral systems and targets similar in style to other notable Australian uranium deposits.

The company’s ongoing work involves field surveys, rock sampling, and geophysical analysis to evaluate both uranium and rare earth potential across its tenements. The integration of tin into its exploration mix further diversifies the company’s critical minerals exposure, enhancing its role in supporting emerging clean energy technologies.
