American Rare Earths Commences Gold, Silver, Copper and Manganese Target Review at La Paz, Arizona
Rhea-AI Summary
American Rare Earths (OTCQX: AMRRY) has engaged a US exploration and geoscience consultancy to review historical data and design targeted follow-up work for gold, silver, copper and manganese at its La Paz Project in La Paz County, Arizona.
The La Paz tenure comprises approximately 2,779 ha (6,866 acres) of federal claims plus a 260 ha (640 acres) state mineral lease. The review will consolidate mapping, re-log historic drill material, re-evaluate geochemistry and assess geophysics, producing a ranked inventory of precious and base metal targets and potential focused follow-up in 2026.

| Date | Event | Sentiment | 24h Move | Catalyst |
|---|---|---|---|---|
| Mar 16 | DOE feedstock selection | Positive | -4.1% | Selected to supply ~5 tonnes of ore to DOE METALLIC consortium. |
| Mar 02 | Leadership consolidation | Positive | +3.2% | President and CEO roles combined to focus on Halleck Creek and U.S. listing. |
| Feb 09 | Shareholder strategy letter | Positive | +1.7% | Outlined Halleck Creek progress, PFS and permit timelines, and funding paths. |
| Jan 22 | University partnership | Positive | +1.9% | UW partnership to study byproducts and tailings from Halleck Creek project. |
| Jan 21 | Policy tailwind commentary | Positive | +3.2% | Commentary on U.S. trade proclamation supporting domestic critical minerals. |
24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Recent company news has generally been positive and has more often seen supportive price reactions, with only one notable divergence on favorable operational news.
Over recent months, American Rare Earths highlighted strategic and technical progress centered on its U.S. rare earth portfolio. A Jan 21 update tied its Halleck Creek resource to U.S. trade policy tailwinds, followed by a Jan 22 university partnership on byproducts. A February shareholder letter emphasized Halleck Creek development milestones and 2026 targets, while a Mar 2 leadership consolidation focused on U.S. listing and major resource assessments. The current La Paz multimetal review extends this strategy by evaluating additional value streams beyond rare earths.

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.”
