Key Terms

rare earth element, lode claims, geochemical, geophysical surveys, +3 more

7 terms

rare earth element technical

"beyond the rare earth element (REE) mineralization on which prior work has primarily"

A rare earth element is one of a set of 17 metallic chemical elements used as essential ingredients in many high-tech products, from smartphones and electric motors to wind turbines and defense systems. Investors care because these metals are critical inputs whose limited, geographically concentrated supply and complex extraction processes can drive price swings and create strategic risks or advantages for companies that mine them or depend on them—like a key spice that can make or break a recipe.

lode claims regulatory

"land package of unpatented federal lode claims, covering approximately 2,779 ha"

A lode claim is a legal right to explore and extract minerals from a defined vein or solid deposit of rock underground. Think of it like owning the right to pull a valuable thread out of a sweater: the claim gives a miner exclusive access to the mineral-bearing rock in a specific area, which directly affects a mining project's size, revenue potential, and investment value because it determines who can legally develop and profit from the resource.

geochemical technical

"Compilation and re-evaluation of historical geochemical datasets, including multi-element"

Geochemical describes the chemical makeup and movement of elements in rocks, soils, water and sediments, and the tests used to measure those chemicals. For investors, geochemical data is like a metal detector for underground clues: it helps exploration teams pinpoint likely mineralization, estimate how rich and extensive a deposit might be, and reduce drilling risk, which directly affects a mining project's value and investment risk.

geophysical surveys technical

"Assessment of historic geophysical surveys (magnetic, radiometric and other"

Geophysical surveys are non-invasive tests that use tools like sound waves, magnets, or electrical signals to map what lies beneath the ground without digging. Think of it as an ultrasound or metal detector for large areas: it reveals hidden structures, rock types, or buried resources. Investors care because these surveys help estimate where valuable minerals, oil, gas, or groundwater might be, reducing exploration uncertainty, cost and risk before costly drilling or mining begins.

resistivity technical

"induced polarization or resistivity for sulphide-rich systems, detailed magnetics"

Resistivity measures how strongly a material opposes the flow of electric current; low resistivity means electricity flows easily, high resistivity means it does not. For investors, resistivity affects the value and suitability of materials used in electronics, power lines, batteries, and sensors—think of it like how narrow or wide a pipe affects water flow: materials with the ‘right’ resistivity can improve product performance, reduce energy losses, or open market opportunities, while the wrong resistivity can limit demand or require costly processing.

sulphide medical

"sulphide-rich systems, detailed magnetics for structural and intrusive features"

A sulphide is a chemical compound in which sulfur is bound to a metal or other element, commonly found in mineral ores such as pyrite or chalcopyrite. For investors, sulphide content matters because it determines how easy or costly it is to extract valuable metals, the type of processing required, and environmental risks like acid mine drainage that can raise cleanup costs and regulatory hurdles — like finding a rotten core in a piece of fruit that needs special handling.

oxide technical

"zones of sulphide, oxide or manganese enrichment that were not the focus"

An oxide is a chemical compound formed when oxygen bonds with another element—common examples include rust on iron or the glassy coating on some metals. Investors care because oxides affect how materials behave (durability, conductivity, or reactivity), influence manufacturing costs and yields, and can trigger safety or environmental rules; changes in oxide-related technology or regulation can therefore alter a company’s expenses, product performance, or market position.

DENVER, March 24, 2026 (GLOBE NEWSWIRE) -- American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) (“ARR” or the “Company”) is pleased to announce that it has engaged an experienced US-based exploration and geoscience consultancy to undertake a comprehensive review of historical data and to design a targeted follow-up work program focused on gold, silver, copper and other non-rare earth critical minerals prospectivity at its La Paz Project in La Paz County, Arizona.

The La Paz Project covers a large, contiguous land package of unpatented federal lode claims, covering approximately 2,779 ha and 6,866 acres, and a state mineral lease, covering approximately 260 ha and 640 acres, in an established mining jurisdiction, where historic activities have included precious and base metal production. Against this backdrop, American Rare Earths sees an opportunity to systematically reassess the multi-commodity potential of the property, beyond the rare earth element (REE) mineralization on which prior work has primarily focused.

Comprehensive review of historical data

The newly engaged US exploration and geoscience firm will lead a multi-phase technical review of all available historical information relating to gold, silver, copper and manganese on the La Paz land position. This work is expected to include:

Consolidation and reinterpretation of historic geological mapping, including structures, alteration patterns and lithological contacts that may control precious and base metal mineralization.

Review and re-logging (where available) of historical drill core and chips to identify untested or under-recognized zones of sulphide, oxide or manganese enrichment that were not the focus of earlier REE-centric programs.

Compilation and re-evaluation of historical geochemical datasets, including multi-element soil, rock chip and stream sediment sampling, with a specific emphasis on pathfinders and anomalism associated with gold, silver, copper and manganese systems.

Assessment of historic geophysical surveys (magnetic, radiometric and other available datasets) to highlight structures and lithological contrasts that could host or focus metallic mineralization.

The outcome of this phase will be a ranked inventory of gold, silver, copper and other critical mineral targets within the broader La Paz tenure, supported by updated geological interpretations and modern geoscientific workflows.

Potential follow-up exploration in 2026

Based on the results of the data review and targeting exercise, American Rare Earths might implement a focused 2026 exploration program to systematically test the most compelling precious and base metal opportunities. Potential follow-up work may include:

• Detailed geological and structural mapping over priority areas to refine target geometries and scale.
• Ground-based geochemical surveys (soil grids, rock chip sampling and channel sampling) to validate and expand historical anomalies for gold, silver, copper and manganese.
• Selective ground geophysics, as appropriate for specific target styles (e.g., induced polarization or resistivity for sulphide-rich systems, detailed magnetics for structural and intrusive features).
• The Company will prioritize work programs that can be efficiently integrated with, or run parallel to, ongoing REE-related activities, leveraging existing access, infrastructure and geological knowledge at La Paz.

Strategic rationale

By systematically reviewing historical data and designing a disciplined follow-up exploration strategy for gold, silver, copper and other critical minerals, American Rare Earths aims to:

• Better understand the broader mineral endowment of the La Paz Project area.
• Identify potential supplementary value streams that could complement any future REE development scenarios.
• Position the Company to respond to growing US demand for domestic sources of critical and strategic metals.
  

American Rare Earths’ CEO, Mark Wall, commented:

“The La Paz Project sits in a region with a long history of gold, silver, and copper mining, yet much of the modern exploration work has understandably focused on rare earth elements. By bringing in a seasoned US geoscience team to take a fresh, multi-commodity look at the data, we are aiming to unlock additional value from this large and strategically located land package. Any success in identifying new gold, silver, copper or manganese targets would add an exciting dimension to La Paz and to our broader US growth strategy.”
