Recent Company History

Over the last month, AREC news has centered on scaling its critical mineral and ReElement strategy. A $5 million credit facility for feedstock procurement, multiple SAGINT blockchain traceability agreements, and an ERI processing partnership all emphasized rare earth and critical mineral positioning. Price reactions ranged from a 2.45% gain to a -17.21% drop. Today’s patent-driven expansion of ReElement’s IP portfolio continues this theme of building refining capabilities and supply-chain relevance.

Market Pulse Summary

This announcement expands ReElement’s IP with five new patent applications targeting ultra-high-purity refining of elements such as antimony, germanium, terbium, gallium, gadolinium, and yttrium, many reaching 99.9%–99.999% purity. Historically, AREC has used ReElement partnerships and financing, like the $5 million credit facility, to strengthen its critical mineral positioning. Filings still note minimal revenue and going-concern risks, so future updates on commercial adoption and balance sheet evolution remain key watch points.

Key Terms

machine learning technical

"Patents developed using advanced software capabilities - including machine learning -"

Machine learning is a set of computer programs that learn patterns from large amounts of data and improve their predictions or decisions over time, like a recipe that gets better each time it’s adjusted based on taste tests. For investors it matters because these systems can speed up analysis, spot trends or risks humans might miss, automate routine work, and potentially create competitive advantages or cost savings that affect a company’s performance.

antimony trisulfide technical

"Antimony: refining to antimony trisulfide or trioxide at 99.7%+ purity"

Antimony trisulfide is a chemical compound made from the metal antimony combined with sulfur; think of it as a stable material created by mixing two basic elements. It is used in products ranging from flame retardants and pigments to certain electronic and ammunition components, so changes in its supply, regulation, or production costs can affect manufacturers, miners and downstream businesses — making it a commodity of interest to investors tracking raw-material risk and price swings.

gallium nitride technical

"Gallium is fundamental to GaN (gallium nitride) power electronics, radar systems,"

Gallium nitride is a durable semiconductor material used to make electronic components that switch faster, handle higher voltages, and waste less energy than older silicon parts. Think of it as a lighter, more efficient motor in an appliance: it lets devices shrink, run cooler and save power, which can lower manufacturing costs, enable new products and boost sales or margins for companies that adopt it—key factors investors watch.

New filings strengthen U.S. supply chain for germanium, antimony, terbium, gallium, gadolinium, yttrium and advanced heavy rare earth separation technologies

Aligning Technology with High-Demand Markets and Immediate Commercial Opportunities

Patents developed using advanced software capabilities - including machine learning - and supported in partnership with Royalty Management Holding Corp. (NASDAQ:RMCO)

FISHERS, IN / ACCESS Newswire / December 10, 2025 / American Resources Corporation (NASDAQ:AREC) ("American Resources" or the "Company") through its minority holding in ReElement Technologies Corporation ("ReElement"), a leading U.S. innovator in rare earth element (REE) and critical mineral refining for the commercial and defense industry, today announced that ReElement has filed five new patent applications that significantly expand its intellectual property portfolio. These filings advance ReElement's position as a leader in clean, modular, and scalable high-purity refining of critical minerals and rare earth elements.

The new patents strengthen the United States' domestic capability to refine antimony, germanium, terbium, gallium, gadolinium, yttrium, and associated heavy rare earth oxides - materials essential to advanced manufacturing, electrification, and national security.

"This milestone underscores how we are building the most versatile and efficient critical mineral refining platform in the world," said Mark Jensen, CEO of ReElement Technologies. "These filings reflect our commitment to reshoring the highest-purity refining of rare earths and critical minerals back to the United States in a manner that is scalable, environmentally responsible, and globally deployable. Our platform enables breakthrough efficiency, lower costs, and the flexibility to co-locate refining directly with mining or concentration operations - an unprecedented advantage for both domestic and allied-nation supply chains."

Advancing ReElement's Leadership in Global Critical Mineral Refining

The patent applications were developed using ReElement's enhanced software capabilities, which build upon the Company's foundational work in advanced separation methods and its proprietary chromatographic refining processes. These tools and expanded IP enable rapid optimization of material separation and higher-efficiency purification tailored to strategic materials. The patent expansion was supported through coordination and non-dilutive financial support by Royalty Management Holding Corp. (NASDAQ:RMCO), which will receive a royalty interest on refined output produced under the patented processes.

The newly filed patents include proprietary and innovative processes for refining high-priority strategic materials to exceptionally high purities:

1. Antimony: refining to antimony trisulfide or trioxide at 99.7%+ purity

2. Gadolinium: refining on a separated basis to 99.9% - 99.999% purity

3. Gallium: refining on a separated basis to 99.5% - 99.999% purity

4. Germanium: refining on a separated basis to 99.9% - 99.999% purity

5. Terbium: refining on a separated basis to 99.5% - 99.999% purity

6. Yttrium: refining on a separated basis to 99.9% - 99.999% purity

These innovations further expand ReElement's proprietary chromatographic separation platform - an environmentally responsible, low-cost, compact, and highly versatile alternative to legacy solvent extraction refineries.

Strategic Importance of These Elements

Germanium - Essential for infrared optics, night-vision systems, satellite sensors, and high-speed electronics. Defense applications often require 5N (99.999%) purity. China currently dominates global processing - elevating the importance of U.S.-based refining.

Yttrium and Gadolinium -Yttrium is critical to laser systems, jet-engine alloys, missile guidance components, and high-temperature ceramics. Gadolinium plays a key role in advanced sensors, neutron detection systems, and specialty alloys. Both materials support cutting-edge defense technologies, require exceptionally high purity and have constrained global refining capacity.

Antimony - Antimony - particularly antimony trisulfide - is a designated defense-critical material used in munitions, primers, flares, and explosives. It is also used in semiconductors, flame retardants, and specialized alloys. The U.S. is almost entirely dependent on foreign nations for its supply, making domestic refining capacity strategically vital.

Terbium and Gallium - Terbium is essential for high-performance permanent magnet alloys used in precision-guided weapons, missile actuators, and advanced electric motors. Gallium is fundamental to GaN (gallium nitride) power electronics, radar systems, secure communications, and high-frequency military semiconductors. Both elements are considered "single point of failure" materials for the U.S. defense supply chain due to limited global processing capacity.

A New Model for Domestic and Allied-Nation Refining Capacity

ReElement's refining platform can be sited quickly, occupies a fraction of the footprint of traditional refineries, and achieves ultra-high-purity outputs with dramatically reduced environmental impact. This enables:

• rapid deployment for domestic or allied-nation supply chains
• co-location with mining or concentration assets
• reduced capital and operating costs
• cleaner, solvent-free processing compatible with U.S. environmental standards
