Heavy Rare Earths Limited (ASX:HRE) positive developments at Prospect Hill Project

Heavy Rare Earths Limited is making significant progress with its Prospect Hill project, located in the mineral-rich northern Flinders Ranges of South Australia, where the company’s recent analysis of historical drill hole data has confirmed the presence of high-grade mineralisation.

Initially considered a major tin (Sn) prospect, the project has now revealed substantial polymetallic potential, with silver (Ag), copper (Cu), zinc (Zn), and lead (Pb) mineralisation identified alongside the previously reported tin assays.

These encouraging results open the door to further exploration, positioning HRE to rapidly transition the South Ridge target into a maiden mineral resource estimate.

Highlights:

• Historic RC drill holes at South Ridge returned high-grade assays, including 1m at 282 g/t Ag, 1.87% Cu, 3.48% Zn, and 3.16% Pb, alongside 2.9% Sn.

• Tin mineralisation at South Ridge extends over 500m of strike and to a depth of 120m, with notable intersections such as 3m at 4.85% Sn.

• The South Ridge prospect, initially focused on tin, now reveals a broader polymetallic potential with significant base metal and silver mineralisation, diversifying HRE’s resource base.

• HRE plans a maiden drilling program aimed at upgrading the existing tin resource and establishing a JORC-compliant Mineral Resource Estimate.

• Recent appointments to the board, including Dr Amanda Buckingham and Mr Graeme Morissey, bring experienced leadership to accelerate exploration efforts at Prospect Hill and other projects.

The Prospect Hill project, which covers 75 km² across three exploration tenements, has shown significant potential for minerals beyond tin, following a re-assessment of historic data.

Previously, South Ridge was a tin-focused prospect, but HRE’s recent evaluation has uncovered significant intervals of base metal and silver mineralisation, which were largely overlooked by earlier operators.

These discoveries have highlighted the polymetallic potential of the area, with the South Ridge target now emerging as a potentially high-value polymetallic deposit.

The high-grade silver and base metals found in the historic drill intersections are driving HRE’s plans to move forward with a drilling campaign designed to upgrade the tin resource and achieve a JORC-compliant Mineral Resource Estimate.

Gabriel Chiappini, Chair of HRE, remarked,

“These are highly significant results, and are primarily from the South Ridge target, from which the company has already reported high-grade tin results including 3m at 4.85% Sn.”

This quote underscores the growing importance of South Ridge as more than just a tin deposit, particularly with the additional value being realised through the polymetallic mineralisation now identified.

Geologically, the South Ridge deposit is hosted within the Curnamona Craton, which provides an ideal setting for polymetallic mineralisation.

The mineralisation at South Ridge is characterised by shear-hosted epigenetic veins with associated high-grade cassiterite, and further exploration work is planned to evaluate the full extent of base metal and silver mineralisation.

With a drilling program planned to test the strike extensions and depth potential, HRE intends not only to upgrade the tin resource but also to assess the overall polymetallic potential of the area, particularly with regard to copper, zinc, lead, and silver.

In addition to the upcoming drilling program, HRE is undertaking a comprehensive suite of exploration activities, including geochemical sampling, trenching, and geological mapping, all of which will help define the next set of drill targets.

With an established and detailed historical database at its disposal, the company is well-equipped to move quickly through the next stages of exploration.

These activities will play a crucial role in upgrading the existing tin resource at South Ridge and in further testing the polymetallic potential of the surrounding area.

HRE has also secured the all-minerals rights to the Prospect Hill project from Havilah Resources, a strategic move that enhances the company’s ability to explore for a broader range of commodities beyond its original focus on uranium and rare earths.

This acquisition strengthens HRE’s position in the region, allowing it to explore additional resources and diversify its portfolio.

Heavy Rare Earths is making significant strides with its Prospect Hill project, which has evolved from a tin-focused exploration site to a polymetallic prospect with substantial silver, copper, zinc, and lead mineralisation.

The recent assay results from South Ridge add considerable value to the project, expanding its potential and positioning HRE for future growth.

The company’s plans to upgrade the tin resource to a JORC-compliant Mineral Resource Estimate, combined with its broader exploration strategy, ensure that HRE is well placed to unlock the full potential of the project.

With an experienced board and a solid exploration program ahead, HRE is poised to make further advancements in both resource definition and exploration.
