## Summary

American Resources and ReElement announced a structured demonstration program with Uzbek partners after reporting high-purity oxide validation. The program is not commissioned commercial throughput or customer qualification.

## What changed

- The parties moved beyond a November 2025 MOU into a U.S.-based commercial-demonstration and engineering program using Uzbek feedstock.
- The program is intended to test commercial viability, efficiency, quality and scalability while evaluating a future Uzbekistan refining deployment.

## Why it matters

The development targets the midstream refining gap that matters more than an additional resource estimate. Demonstration output, customer specifications and recurring volume remain unproven.

## Evidence

- [American Resources and ReElement: Uzbekistan tungsten program](https://www.nasdaq.com/press-release/american-resources-corporation-and-reelement-technologies-advance-strategic) — Agreement scope, prior validation claim and commercial-demonstration objectives; issuer release carried by Nasdaq.
