Metallium Strengthens U.S. Defence Connection with Pentagon Veteran Appointment

Metallium Strengthens U.S. Defense Connections with High-Profile Advisory Board Appointment

Metallium Limited (ASX: MTM; OTCQX: MTMCF) has appointed former U.S. Deputy Assistant Secretary of Defense Travis Langster to its Flash Metals USA Advisory Board, significantly enhancing the company's strategic positioning within U.S. defense and critical metals sectors.

Pentagon Veteran Brings Crucial Defense and Space Policy Experience

In a move that signals Metallium's growing alignment with U.S. national security priorities, the company has secured the services of Travis Langster, who brings exceptional credentials to the Flash Metals USA Advisory Board:

• Former Deputy Assistant Secretary of Defense for International & Industry Engagement
• Principal Director of Space and Missile Defense Policy
• Led the development of the DoD's inaugural Commercial Space Integration Strategy in April 2024
• Spearheaded efforts to modernize the U.S. defense industrial base
• Established key focus as the DoD acquisition lead for the AUKUS Advanced Capability Industry Forum

This appointment significantly strengthens Metallium Ltd U.S. defense connection and international supply chains, particularly in strategic regions like Japan and Taiwan.

"Travis brings a unique combination of U.S. defense leadership, international policy expertise, and strong industry connections across the electronics and semiconductor supply chains. His background in fortifying the U.S. defense industrial base and shaping space and missile defense policy will be invaluable as Metallium executes its strategy to assist the U.S. effort to secure and process a domestic supply of critical and strategic metals." – Michael Walshe, Metallium's Managing Director & CEO

Building a Strategic Advisory Powerhouse

Langster's appointment follows the earlier addition of Greg Bowman to the Advisory Board in July 2025, forming part of Metallium's broader initiative to build world-class advisory capabilities for its U.S. operations.

The growing Advisory Board will guide Flash Metals USA as it commercializes the company's Flash Joule Heating technology from its base in Houston, Texas. Langster will receive quarterly fees and performance rights in Metallium Ltd, vesting over 12 months, aligning his incentives with shareholder outcomes.

Understanding Flash Joule Heating: Revolutionizing Metal Recovery

Flash Joule Heating represents a breakthrough in materials processing technology, offering significant advantages over traditional extraction methods:

• Ultra-fast, selective thermal process
• Recovers critical metals without acids or smelting
• Environmentally superior with low emissions
• Modular and scalable deployment model
• Aligned with U.S. industrial modernization goals

This proprietary technology enables Metallium to target high-value materials that are essential to defense, electronics, and renewable energy sectors, including rare earth elements, antimony, gallium, germanium, indium, and precious metals like gold, silver, copper, and tin.

The Science Behind Flash Joule Heating

Flash Joule Heating involves applying a brief but intense electrical pulse through a conductive material, generating temperatures of several thousand degrees Celsius within milliseconds. This rapid heating selectively targets and liberates valuable metals while avoiding many environmental issues associated with conventional extraction methods.

The process works by:

1. Preparing feedstock material (e.g., electronic waste, mine tailings)
2. Applying precise electrical pulses to create ultra-high temperatures
3. Selective liberation of target metals through thermal decomposition
4. Collection and separation of the valuable materials
5. Production of high-purity metal outputs or intermediates

Unlike traditional hydrometallurgical or pyrometallurgical processes, Flash Joule Heating requires minimal chemical inputs, produces fewer waste streams, and consumes less energy per unit of metal recovered. The modularity of the technology also allows for deployment at various scales, from small processing facilities to larger industrial operations.

Strategic Alignment with U.S. Supply Chain Security

Langster's appointment comes at a pivotal moment as the United States intensifies efforts to secure domestic supply chains for strategic materials. His experience in defense industrial base modernization directly complements Metallium's mission.

"The United States and its allies face an urgent need to secure resilient, sustainable supply chains for critical and strategic materials, particularly for the electronics and defense sectors. Metallium's technology platform is a transformative and scalable solution to these challenges, and I look forward to supporting the team's mission to advance U.S. industrial base modernization and global supply chain resilience." – Travis Langster

The appointment reinforces Metallium Ltd U.S. defense connection at the intersection of several key U.S. national priorities:

• Defense Supply Chain Security: Reducing dependence on foreign sources for critical materials
• Industrial Base Modernization: Supporting the development of advanced manufacturing capabilities
• Environmental Sustainability: Deploying cleaner processing technologies with lower emissions
• Circular Economy: Recovering valuable materials from waste streams to reduce resource depletion

Commercial Progress Underway in Texas

Metallium is already making tangible progress on its commercialization pathway. Through Flash Metals USA, the company has secured its first commercial site in Chambers County, Texas, where it is developing a processing facility targeting:

• Strategic metals recovery including rare earth elements and critical semiconducting metals
• Precious metals extraction from various waste streams
• Production of chloride intermediates for REE magnet and semiconductor markets

This facility represents a major step toward near-term production and revenue generation, with operations designed to be modular, low-emission, and aligned with U.S. industrial priorities.

Why Investors Should Monitor Metallium

Metallium presents a compelling investment case for those focused on critical materials, strategic metals, and defense sector innovations:

1. Strategic Positioning: Direct alignment with U.S. national security priorities and critical supply chain initiatives
2. Proprietary Technology: Patented Flash Joule Heating process offers environmental and efficiency advantages
3. High-Value Target Metals: Focus on materials essential to electronics, defense, and renewable energy sectors
4. Commercial Progress: First processing facility underway in Texas
5. Elite Advisory Network: Growing team of defense and industry experts enhancing government engagement

The appointment of Travis Langster strengthens the Metallium Ltd U.S. defense connection at a time when securing domestic supply of critical metals has become a national security imperative for the United States. With commercialization efforts advancing in Texas and a strengthening advisory team, Metallium is positioning itself at the intersection of clean technology, defense priorities, and advanced manufacturing.
