Critica Unlocks Gallium Recovery from Jupiter’s 1.8 Billion Tonne Resource

Critica's Jupiter Project Delivers Major Strategic Breakthrough: Gallium Recovery Opens New Revenue Stream in $1.8 Billion Tonne Resource

Critica gallium recovery has achieved a significant milestone, with Critica Limited (ASX: CRI) confirming that gallium oxide can be extracted as a valuable by-product within the same processing circuit that produces their Mixed Rare Earth Products (MREP). The breakthrough demonstrates 63% gallium recovery from the company's established beneficiation-first flowsheet, adding a strategic new revenue stream to Australia's largest clay-hosted rare earth resource.

The Jupiter deposit contains approximately 70,000 tonnes of gallium oxide across its 1.8 billion tonne resource, with grades averaging 39 ppm gallium oxide and localised zones exceeding 50 ppm. Furthermore, this discovery significantly enhances the project's economics without requiring changes to the existing process scope or strategy.

Understanding Gallium: The Critical Metal China Controls

What is Gallium and Why Does It Matter?

Gallium represents a critical metal essential for manufacturing next-generation semiconductors, advanced defence systems, and high-efficiency solar panels. Unlike rare earths, gallium has extremely limited global supply sources, with China controlling over 98% of global production and implementing export licence controls since 2024.

For instance, investors should recognise that gallium offers:

• Strategic scarcity: Minimal alternative supply sources outside China
• High-tech demand: Essential for 5G infrastructure, military radar systems, and space technology
• Supply security premium: Western nations actively seeking alternative supply chains
• Co-product economics: Can significantly improve project margins when recovered alongside primary products

The metal's unique properties make it irreplaceable in compound semiconductors (gallium arsenide). These compounds are superior to silicon in high-frequency and high-power applications critical for defence and telecommunications infrastructure.

Processing Breakthrough Validates Integrated Recovery Strategy

Critica gallium recovery testwork has confirmed that gallium extraction integrates seamlessly within their proven rare earth processing circuit. The 63% gallium recovery rate was achieved using the same acid-bake and leach process that delivered their first 84% TREO Mixed Rare Earth Product at 78% recovery.

Key Technical Achievements

However, the breakthrough eliminates the need for separate processing infrastructure. In addition, it maintains Critica's focus on capital-efficient development while adding significant by-product value potential.

Strategic Timeline: From Pilot to Production

Critica has established a systematic de-risking pathway that positions the company for rapid advancement through development studies.

Immediate Priorities (Q4 2025 – H1 2026)

The company will focus on several critical activities:

• 3,000 kg closed-circuit pilot operations to generate continuous operating data
• Hydrometallurgical optimisation across GAVAQ, ANSTO, and Minutech-AMML facilities
• Selective precipitation trials for gallium product specification
• Co-product evaluation of germanium and scandium opportunities

Development Integration (H1 – H2 2026)

Furthermore, the development phase will include:

• Scoping Study completion incorporating gallium by-product economics
• Pre-Feasibility Study advancement with integrated product streams
• Offtake discussions with Western-aligned technology partners
• Product qualification for defence and semiconductor applications

This timeline leverages Critica's existing metallurgical infrastructure and established research partnerships. Consequently, it accelerates commercial validation significantly.

Investment Thesis: Strategic Scale Meets Western Supply Security

Jupiter Project represents a unique investment opportunity combining substantial resource scale with strategic positioning advantages.

Resource Scale and Quality

Strategic Positioning Advantages

The project benefits from exceptional location advantages:

• Tier 1 Western Australia location with established mining infrastructure
• 60 kilometres from Mount Magnet providing access to skilled workforce
• Direct highway access to Port of Geraldton for export logistics
• Proximity to gas pipeline and electrical transmission infrastructure

Geopolitical Value Creation

The combination of rare earths and gallium positions Jupiter as a strategic alternative to Chinese supply chains. Moreover, with China controlling 98% of gallium production and implementing export restrictions, Western governments are prioritising supply chain diversification for both rare earths and gallium.

Why Investors Should Track Critica's Development

Critica gallium recovery success has assembled multiple value drivers that distinguish it from typical rare earth explorers.

"Jupiter combines Australia's largest clay-hosted REE resource with significant gallium by-product potential, offering investors exposure to two critical mineral supply chains under Chinese export control."

Competitive Differentiators

What Catalysts Could Drive Value Creation?

Several key milestones will determine the project's advancement:

• Q4 2025: Pilot plant operating data and gallium product specifications
• H1 2026: Scoping Study with integrated by-product economics
• H2 2026: Pre-Feasibility Study and offtake negotiations
• Ongoing: Western government critical minerals initiatives and funding opportunities

Investment Rationale and Future Outlook

Critica offers investors exposure to Australia's largest rare earth resource with added gallium by-product potential. The company positions itself as a strategic alternative to Chinese-controlled supply chains through systematic de-risking approaches.

The established processing partnerships and Tier 1 jurisdiction advantages create multiple pathways for value creation. This becomes particularly relevant as global supply chain diversification accelerates across critical minerals sectors.

With upcoming pilot operations and study completions, investors should monitor Critica's progression from metallurgical validation toward commercial development. The successful demonstration of Critica gallium recovery alongside rare earth production positions the company uniquely.

In conclusion, this dual-product opportunity operates within an increasingly constrained global supply environment. However, the strategic combination of resource scale, processing innovation, and geopolitical positioning creates compelling investment fundamentals for those seeking critical minerals exposure.
