r/ARRNF

Hey dudes.

Just saw this this morning. Seems ARRNF is making big moves before the nasdaq listing. They just hired a guy named Nick Lissolo as VP Chief Commercial Officer. He's a Newmont Corp Mining veteran and a University of Wyoming Grad.

I've included the news story and a quote from the guy's linkedin about it. Would be curious to know your thoughts

LINKEDIN QUOTE:

"Excited to announce I've joined American Rare Earths as Vice President, Corporate Development and Strategy.

Halleck Creek is one of the most strategically important rare earth deposits in North America and it sits in the state I'm from.

The timing couldn't be more relevant. Rare earths are at the center of the energy transition, defense supply chains, and the broader push for critical mineral independence. The U.S. needs domestic sources, and projects like Halleck Creek are how we get there.

A lot of exciting work ahead."

-Nick Lissolo

ARR's proposed commercial chain

HALLECK CREEK, WYOMING

Mining: Open pit mining of Halleck Creek ore at the Cowboy State Mine
Comminution: Crushing/grinding/milling the ore
Beneficiation: ARR is currently favoring a Reflux Classifier Concentrator (RCC) followed by Induced Roll Magnetic Separation (IRMS). ARR's April 2026 pilot work showed roughly 94% gangue rejection, ~70% TREO recovery and ~10× grade enrichment in preliminary testing
Atmospheric leaching: The upgraded concentrate goes through atmospheric tank leaching. This is the hydrometallurgical step where the rare earths are brought into solution.
Impurity removal: ARR has been testing magnesium oxide (MgO) as the neutralizing reagent. The objective is to remove impurities such as iron, aluminum, silica, thorium and titanium while retaining the rare earths in solution.
Mixed rare-earth oxalate: Rare earths are selectively precipitated from the purified leach solution using oxalic acid. ARR has already demonstrated this step.
Calcination: The mixed rare-earth oxalate is heated to approximately 1,000°C, converting it into mixed rare-earth oxide (MREO). ARR produced MREO from Halleck Creek material in December 2025.
Solvent extraction / separation: The MREO is the feedstock for solvent extraction, which separates the individual rare earths. This is where the mixed product gets turned into individual products such as: NdPr oxide | Dy oxide | Tb oxide | Sm oxide | Y oxide. ARR's December release specifically identified solvent extraction as the next step and said simulation work was being used to define the separation refinery.
Oxide to Metal: Novex's role under the MOU is specifically to take NdPr oxide produced from ARR's demonstration plant and convert it into a metal product suitable as a magnet precursor.
Metal to Alloy to Magnet: "The parties will collaborate on the design of a rare earth metal production facility to be built by the Company" with "Objective is a fully domestic U.S. mine-to-magnet supply chain with entirely U.S. feedstock and processing"

Latest Significant News:

Dec 2025 - ARR demonstrates Halleck Creek ore into MREO

Mar 2026 - ARR commissions Tetra Tech to figure out separated HREE oxide into HREE metal

Apr 2026 - ARR accelerates its pilot plant to produce pre-production material

Aug 2026 - ARR NdPr oxide will go to Novex to create NdPr metal. ARR + Novex to design a U.S. rare-earth metal facility

Notes:

Novex is the first concrete partner ARR has announced specifically for that oxide-to-metal bridge.
