Heavy Rare Earths Expands Radium Hill Mineral Rights Amid Yttrium Surge

HRE Secures Major Upgrade to Radium Hill Rights as Yttrium Prices Soar 30-Fold

Heavy Rare Earths Limited (ASX:HRE) has announced a significant expansion of its Heavy Rare Earths Radium Hill mineral rights at the project in South Australia, transforming a limited agreement into comprehensive access to all minerals including critical minerals, precious metals, and base metals. The timing couldn’t be better, with yttrium prices surging over 3,000% from $10/kg to $320/kg in European markets throughout 2025.

The expanded agreement with Havilah Resources (ASX:HAV) comes at zero additional cost to HRE and provides investors with substantially increased leverage across the company’s 8km Critical Minerals Corridor. This corridor has already delivered impressive surface sampling results including yttrium grades up to 2,236ppm, alongside significant scandium, uranium, and rare earth elements.

Furthermore, the company’s strategic positioning in the Curnamona Province demonstrates significant geological potential for continued exploration success.

Key Development: “There hasn’t been a hole drilled at Radium Hill for over 60 years and during 1st half 2026, we plan to drill along the 8km critical minerals’ corridor.” – Gabriel Chiappini, Chair of the Board

All Minerals Agreement Creates Multi-Commodity Opportunity

The amendment transforms HRE’s position at Radium Hill from a selective minerals agreement to comprehensive access across the entire commodity spectrum. This strategic upgrade positions the company to capitalise on multiple market opportunities simultaneously.

Key Agreement Terms:

• Expanded scope: All minerals now included (previously limited subset)

• Zero cost: Havilah waived the $1 million minimum spend requirement

• Strategic focus: 8km Critical Minerals Corridor identified as priority target

• Retained rights: HRE keeps prospective Billeroo Paleochannel uranium area

The company’s recent reconnaissance sampling program has validated the corridor’s potential with multiple high-grade intersections across considerable strike length. Notably, yttrium and vanadium were not previously covered under the original agreement, making this expansion particularly valuable given current market dynamics.

The amendment also allows HRE to concentrate resources on the highest-value targets whilst maintaining strong relationships with joint venture partners. In addition, understanding the critical minerals market remains essential for investors evaluating this sector’s potential.

Havilah retains rights to iron ore and co-minerals within Neoproterozoic rocks in a small area at Radium Hill, creating a focused partnership structure that benefits both parties.

Understanding Yttrium: The Critical Mineral Driving EV Revolution

What is Yttrium?

Yttrium is a rare earth metal essential for manufacturing high-performance superconductors, LED lighting systems, and advanced battery technologies. Its unique properties make it irreplaceable in modern electronics and clean energy applications.

The silvery-metallic element belongs to the rare earth group and is particularly valued for its ability to enhance the performance of various technological applications. Yttrium compounds are crucial in producing phosphors for energy-efficient lighting, whilst yttrium-based superconductors operate at higher temperatures than traditional alternatives.

Why It Matters to Investors

The 30-fold price increase reflects growing global demand driven by the electric vehicle revolution and renewable energy infrastructure buildout. Unlike more common rare earths, yttrium supply is highly concentrated, creating significant pricing power for producers.

With grades up to 2,236ppm identified at Radium Hill, HRE is positioning itself in a market experiencing unprecedented growth. The European market pricing surge from $10/kg to over $320/kg demonstrates the critical supply-demand imbalance that creates substantial opportunities for new producers.

However, investors should also consider the broader rare earth elements landscape when evaluating market opportunities. The price movement represents one of the most dramatic commodity rallies in recent years, driven by technological advancement and supply constraints.

For exploration companies with proven yttrium mineralisation, this creates exceptional leverage to commodity price appreciation.

Project Portfolio Optimisation Strengthens Focus Areas

The agreement restructuring has strategically consolidated HRE’s project focus whilst maintaining access to the most prospective ground:

This restructuring allows HRE to concentrate resources on the highest-value targets whilst maintaining strong relationships with joint venture partners. The Billeroo Paleochannel retention is particularly strategic, given its proximity to established uranium resources.

The company has agreed for Havilah to retain the Namba Uranium Paleochannel ground at the Billeroo Namba project, whilst HRE retains rights to the Billeroo Paleochannel area that the company believes to be more prospective for uranium. Consequently, this focused approach enables both parties to concentrate on their preferred exploration targets.

Furthermore, the strategic emphasis on uranium exploration complements the company’s diversified mineral portfolio approach.

First Drilling Program in Over 60 Years Planned

HRE is preparing to break a six-decade drilling drought at Radium Hill with a comprehensive program targeting the Critical Minerals Corridor. The maiden drilling campaign, planned for the first half of 2026, will test multiple high-grade surface targets across the 8km strike length.

The drilling program is subject to permit and consent approvals, with the company actively progressing regulatory requirements. The 60-year absence of drilling activity at Radium Hill presents a unique opportunity to apply modern exploration techniques to historically proven geological terrain.

Upcoming Catalysts:

• Q1 2026: Permit and consent approvals expected

• H1 2026: Maiden drilling program commences

• Mid-2026: Initial drilling results anticipated

• H2 2026: Expanded program based on initial success

The timing aligns perfectly with favourable market conditions for critical minerals, particularly yttrium’s extraordinary price performance. With surface sampling already confirming significant mineralisation across considerable strike length, the drilling program could unlock substantial value for shareholders.

For instance, the implementation of modern drilling techniques in this historically proven terrain represents a significant technological advancement over previous exploration efforts.

Management Commentary:
“The recently refreshed team at HRE are excited to start the year and commence exploration at the company’s prospective project portfolio. We continue to enjoy and appreciate positive relationship with Havilah Resources.” – Gabriel Chiappini, Chair of the Board

Why This Drilling Program Matters

The extended period without drilling activity means that the Heavy Rare Earths Radium Hill mineral rights area remains largely untested by modern exploration standards. This creates exceptional discovery potential when combined with contemporary geological understanding and advanced drilling technologies.
