Key Terms

feedstock, critical minerals and materials, mineral processing, process flowsheets, +2 more

6 terms

feedstock technical

"has been selected to provide feedstock for the Department of Energy (DOE)..."

Feedstock is the raw material—such as crude oil, natural gas, agricultural crops, or recycled plastics—used as the primary input to make fuels, chemicals, plastics, or other industrial products; think of it as the ingredients you put into a factory recipe. For investors, feedstock matters because its price, supply stability and quality directly shape producers’ costs, profit margins and ability to meet demand, so shifts in feedstock markets can alter company earnings and valuations.

critical minerals and materials technical

"to establish new, domestic critical minerals and materials (CMM) supply chains."

Critical minerals and materials are natural elements and compounds—like lithium, cobalt, rare earths and certain metals—that are essential for making modern technologies such as batteries, electronics, renewable energy systems and defense equipment. They matter to investors because shortages, difficult extraction, or concentrated supply sources can raise costs, disrupt operations and create strategic risks or opportunities, much like a missing part can stop a factory line or a recipe.

mineral processing technical

"METALLIC researchers will employ mineral processing methods developed by ARR..."

Mineral processing is the set of industrial steps that turn raw rock pulled from a mine into concentrated metal- or mineral-rich material ready for sale or further refining. Think of it like a kitchen process that washes, breaks up, and sorts ingredients to get the useful parts; the efficiency, cost and environmental footprint of those steps directly affect a mining project’s output, profit margins, and regulatory risks, so investors watch it closely.

process flowsheets technical

"ARR benefits from third-party affirmation of process flowsheets."

A process flowsheet is a clear diagram that maps the sequence of steps, equipment, material inputs and outputs, and basic controls in an industrial or manufacturing operation—think of it as a recipe or road map for how a product is made. For investors, flowsheets matter because they reveal how complex and efficient a process is, where costs, delays or safety risks may arise, and how easily production can be scaled or modified, all of which affect capital needs, margins and regulatory exposure.

rare earth elements technical

"methods for capturing and refining magnetic rare earth elements."

Rare earth elements are a set of 17 chemical metals used to make powerful magnets, batteries, catalysts and many tiny components inside electronics, renewable energy equipment and defense systems. They matter to investors because they are essential inputs for fast‑growing industries, and limited or concentrated supply can drive prices, create production bottlenecks or shift competitive advantage — like a factory running short of a specialized ingredient that halts output and affects profits.

test pit technical

"allanite ore from the Cowboy State Mine test pit for METALLIC research1."

A test pit is a small, shallow excavation dug to collect rock, soil or ore samples and check whether valuable minerals or environmental issues are present before bigger work begins. For investors, test pits are an early, lower-cost way to gauge a site's potential and reduce uncertainty—think of them as tasting a spoonful to decide whether it’s worth ordering the whole meal, helping inform investment risk and next steps.

DENVER, March 16, 2026 (GLOBE NEWSWIRE) -- American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) (“ARR” or the “Company”) has been selected to provide feedstock for the Department of Energy (DOE) Minerals to Materials Supply Chain Research Facility (METALLIC) consortium being led by the National Energy Technology Laboratory to establish new, domestic critical minerals and materials (CMM) supply chains. In December 2025, ARR provided approximately 5 tonnes of allanite ore from the Cowboy State Mine test pit for METALLIC research¹. The METALLIC consortium combines the research resources of nine national labs to validate, improve, and help commercialize technologies developed by domestic entities, amplifying the impact of the DOE and other U.S. government investments. This innovative approach fosters an ecosystem of expertise and capabilities for accelerating and de-risking CMM technology development and commercialization².

As one of the key feedstocks for the program, ore from the Cowboy State Mine (“CSM”) at the Halleck Creek Rare Earths Project provides a rare earth bearing material for use in each of the four METALLIC test centers. In collaboration with ARR, METALLIC researchers will employ mineral processing methods developed by ARR and then test novel processing methods. With METALLIC employing ARR’s processes, ARR benefits from third-party affirmation of process flowsheets. Testing of novel processes could also benefit ARR by discovering more efficient and cost-effective methods for capturing and refining magnetic rare earth elements.

Chief Executive Officer, Mark Wall, commented, “Supporting a Department of Energy program is an exciting step for the company as we focus in on advancing the largest US domestic rare earths deposit³. American Rare Earths benefits by having leading DOE scientists processing our ore as a part of the drive to domestic rare earth supply chain security within the United States.”

ARR has enjoyed previous collaborations with research professionals from Lawrence Livermore National Laboratory (LLNL), Idaho National Laboratory (INL) and Oak Ridge National Laboratory (ORNL). The METALLIC consortium provides the opportunity for everyone to work together.

ARR will continue to inform the market and our investors about this exciting collaboration as research advances.
