Shares in Metals One PLC (AIM:MET1, FRA:HT7, OTCQB:MTOPF) were up 19% at 1.74p on Monday, extending a rally that has seen the stock gain 50% since the start of trading on Friday after the critical metals developer expanded an agreement to evaluate and potentially treat abandoned uranium mine waste in Colorado.
The deal with DISA Technologies covers eight separate waste dumps across the 490-hectare Uravan Belt project near the historic Buckhorn Mine.
DISA will deploy its patented high-pressure slurry ablation technology, a modular mobile process that extracts uranium and other critical minerals from surface waste while removing around 90% of uranium and radium-226 content.
The arrangement requires no capital or operating expenditure from Metals One, with DISA covering all costs of permitting, evaluation, treatment and remediation in return for Metals One receiving a gross revenue share of between 2.5% and 4.0% on saleable concentrates depending on metals pricing.
The Uravan Mineral Belt produced more than 60 million pounds of uranium and 330 million pounds of vanadium during the 20th century, and rock chip assays announced in September 2025 returned grades of up to 4.17% uranium from historic waste material.
The agreement expands on an existing relationship covering Metals One’s Radium Mountain and Wedding Bell claims, also in Colorado, where managing director Daniel Maling said DISA had made strong early progress with gamma walkover data expected by the end of May.
