America Just Added a Massive New Rare Earth Supply Source
REalloys (NASDAQ: ALOY) said it signed a Letter of Intent with Patriot Exploration & Mining for priority allocation to up to 30% of production from a 2-billion-ton Appalachian rare earth resource network across 150+ tested sites in the U.S. The feedstock includes neodymium, praseodymium, dysprosium and terbium, supporting U.S. defense supply-chain goals ahead of a 2027 Chinese-origin materials ban.
How this was made

The 30-second read
Why it matters
REalloys’ LOI with Patriot adds quantified priority access to Appalachian heavy rare-earth-bearing production, strengthening upstream supply optionality for its downstream processing/metallization platform.
Market read
A concrete, defense-timeline-linked feedstock agreement for REalloys is the article’s main tradable catalyst; it may improve perceived supply-chain de-risking versus peers.
What to watch
Execution risk remains across the chain (feedstock testing-to-production conversion, separation/metallization capacity ramp, and whether defense demand timing matches the 2027 deadline).
Background
The article frames a U.S. defense-driven push to secure non-Chinese rare-earth supply chains ahead of a Pentagon 2027 ban on Chinese-origin materials.
Ticker impact
REalloys signed a Letter of Intent with Patriot Exploration & Mining for priority allocation to up to 30% of production from a 2B-ton Appalachian rare-earth resource network.
Potentially positive near-term sentiment as investors price improved feedstock availability and timeline alignment to defense demand.
The article discloses a specific LOI, quantified priority allocation (up to 30%), and ties it to a concrete policy deadline (2027) that affects rare-earth supply-chain risk.
MP Materials is described as securing a 2025 DoD partnership with a $400M equity investment, a 10-year NdPr oxide price floor, and a 10-year magnet offtake agreement.
Limited incremental price impact from this article alone; may support existing bullish positioning around DoD-backed contracts.
The article provides details of previously secured arrangements (2025) and does not indicate a fresh contract award or new financial print for MP in the current text.
Critical Metals (CRML) is identified as the counterparty holding a 92.5% stake in the Tanbreez project and as the seller under REalloys’ 15% Phase 1 offtake agreement.
Potentially supportive for CRML sentiment, but the article frames the offtake as “last month,” limiting incremental novelty today.
The article does not present a newly disclosed CRML-specific event in the current day; it mainly contextualizes an already-signed offtake and project status.
Market effects
Reinforces the read-across that U.S./allied rare-earth feedstock access is becoming a competitive bottleneck ahead of 2027 China-origin restrictions, potentially lifting sentiment across domestic processing/metallization names.
Appalachian Basin feedstock focus (Alabama–Pennsylvania) plus Saskatchewan processing and Ohio metallization highlights a multi-region buildout that could shift attention to North American midstream capacity constraints.
Continues the geopolitical re-routing away from China by emphasizing Western control of heavy rare-earth streams (dysprosium/terbium) from Greenland and domestic/allied resources.
Counterpoint
Priority allocation via LOIs may not fully translate into contracted volumes or near-term cash flows until permitting, offtake terms, and throughput ramp are finalized.
