ABx Group Strikes Gold with Tasmania's Highest-Grade Critical Rare Earths Discovery
ABx Group (ASX: ABX) has successfully extended its groundbreaking T8 ABx Group rare earths discovery in northern Tasmania, with the first three drill holes encountering target mineralisation within 0.5 metres of surface. The company's lightweight drilling programme has confirmed exceptional grades of dysprosium (Dy) and terbium (Tb) – the most valuable heavy rare earths that China recently restricted exports on.
This remarkable ABx Group rare earths discovery represents a potential game-changer for Western supply chains. Furthermore, ABx boasts the highest Dy and Tb grades of any ionic adsorption clay deposit in Australia and ranks amongst the highest globally.
With shallow mineralisation starting at just half a metre depth, this project offers a low-cost, low-impact pathway to production. The exceptional positioning provides investors with unprecedented access to critical materials from a stable Western jurisdiction.
The Discovery That's Reshaping Australia's Rare Earth Landscape
ABx's latest drilling campaign has struck the jackpot at the T8 prospect, building on the company's May 2024 scout drilling success. The standout hole TB008 delivered spectacular results, particularly in the critical 2-3 metre interval.
The results demonstrate consistent high-grade mineralisation across multiple depth intervals. In addition, the hole ended whilst still in mineralisation, suggesting further potential for resource expansion.
| Depth Interval | TREO (ppm) | Dy₂O₃ (ppm) | Tb₄O₇ (ppm) | Permanent Magnets REE (%) |
|---|---|---|---|---|
| 0-1m | 276 | 39 | 10 | 3.2% |
| 1-2m | 5,318 | 849 | 213 | 22.9% |
| 2-3m | 1,404 | 206 | 51 | 4.6% |
The exceptional quality becomes clear when examining the permanent magnet rare earth content. These are the elements essential for electric vehicles, wind turbines, and military applications. Notably, the 1-2 metre interval alone contains nearly 23% permanent magnet REEs.
Understanding Ionic Adsorption Clay Deposits: The Premium Rare Earth Source
Ionic adsorption clay deposits represent the premium tier of rare earth mineralisation. Unlike hard rock deposits that require energy-intensive processing, these clay-hosted deposits allow rare earths to be extracted using simple acid leaching methods.
This process resembles steeping tea leaves in hot water rather than complex metallurgical operations. Consequently, the extraction method offers significant advantages for commercial development.
Why This Matters to Investors
The benefits of ionic adsorption clay deposits extend far beyond simple extraction:
- Lower processing costs – no crushing, grinding, or flotation required
- Higher recovery rates – typically 80-90% versus 60-70% for hard rock
- Faster development – minimal infrastructure needed for shallow deposits
- Environmental advantages – smaller footprint and lower water usage
The rare earths in these clay deposits are held loosely on the surfaces of clay particles through electrical charges. When exposed to mild acid solutions, the rare earths readily dissolve into the liquid, allowing for efficient extraction.
This process requires significantly less energy compared to traditional hard rock mining methods. Moreover, the environmental impact remains substantially lower than conventional mining operations.
China dominates global production precisely because most of their rare earth output comes from ionic adsorption clays. However, the ABx Group rare earths discovery brings this same geological advantage to a stable Western jurisdiction.
Strategic Timing Couldn't Be Better
ABx's rare earth developments align perfectly with escalating geopolitical tensions and supply chain concerns. China's recent export restrictions on critical materials like dysprosium and terbium have sent shockwaves through Western manufacturing.
These restrictions particularly affect key sectors including:
- Electric vehicle production – permanent magnet motors require Dy and Tb
- Offshore wind turbines – generator magnets need heavy rare earths
- Military applications – guided missiles and radar systems
- Consumer electronics – smartphones, laptops, and audio equipment
Industry Leadership Recognises the Opportunity
Dr Mark Cooksey, Managing Director, stated: "China's restriction on exports of critical heavy rare earths, especially Dy & Tb, sends a clear message to the global market and ABx is in a unique position with its Dy & Tb-rich shallow clay-hosted rare earth deposit in a stable jurisdiction."
The company has already established strategic partnerships with US-based Ucore. Importantly, Ucore is developing a Strategic Metals Complex in Louisiana with US Government backing, providing ABx with a clear pathway to market.
This partnership creates direct access to customers willing to pay premium prices for secure supply chains. Furthermore, the strategic alliance positions ABx at the forefront of Western rare earth development.
Next Steps: Rapid Resource Expansion and Processing Validation
ABx is executing a methodical development strategy designed to capitalise on the exceptional ABx Group rare earths discovery. The company's systematic approach focuses on rapid advancement whilst maintaining technical rigour.
Immediate Priorities (Q4 2024 – Q1 2025)
The near-term focus centres on resource definition and product validation:
- Complete current drilling programme to define resource extensions
- Await mixed rare earths carbonate sample results from ANSTO processing of Deep Leads bulk sample
- Engage with potential customers for offtake discussions
Medium-term Catalysts (2025)
The development pathway extends through multiple value-creating milestones:
- Resource estimation and JORC compliance reporting
- Preliminary economic assessment
- Permitting advancement for larger-scale operations
- Processing facility planning with international partners
| Milestone | Target Timeline | Significance |
|---|---|---|
| ANSTO processing results | Q4 2024 | Product validation for customers |
| Resource expansion drilling | Q1 2025 | Increased project scale |
| Economic assessment | Mid-2025 | Investment decision framework |
| Permitting completion | Late 2025 | Production pathway clarity |
Investment Thesis: Why ABx Group Deserves Attention
ABx Group presents a compelling rare earth investment opportunity built on four key pillars. Each pillar reinforces the company's strategic positioning in the critical materials sector.
Exceptional Resource Quality
The company's Tasmanian deposits contain the highest dysprosium and terbium grades of any ionic adsorption clay deposit in Australia. With permanent magnet REE content reaching 22.9% in key intervals, ABx's mineralisation quality rivals the best Chinese deposits.
This grade advantage translates directly into superior project economics. In addition, the high-grade nature reduces processing requirements and environmental impact.
Strategic Market Positioning
China's export restrictions have created unprecedented demand for alternative supply sources. However, ABx's partnership with Ucore provides direct access to US military and industrial customers willing to pay premium prices for secure supply.
The strategic positioning extends beyond simple market access. Furthermore, the partnership provides technical expertise and processing capabilities essential for rapid development.
Low-Cost Development Profile
Shallow mineralisation starting at 0.5 metres depth combined with ionic adsorption clay geology creates an exceptionally low-cost development scenario. The lightweight drilling programme demonstrates minimal environmental impact, supporting rapid permitting.
This development profile significantly reduces capital requirements compared to traditional mining operations. Moreover, the shallow nature eliminates complex underground infrastructure requirements.
Diversified Project Portfolio
Beyond rare earths, ABx operates across three priority sectors:
- ALCORE fluorine chemicals – pilot plant under construction
- Bauxite projects – $2.7 million initial payment received from Good Importing International
- Heavy rare earths – the crown jewel Tasmanian discoveries
This diversification provides multiple pathways to value creation whilst reducing project-specific risks.
