Expansion of Agreement to Treat Uranium Waste Dumps with DISA Technologies

 

Metals One (AIM: MET1, OTCQB: MTOPF), a critical and precious metals project
developer and investor, announces it has signed an agreement with DISA
Technologies Inc. ("DISA") to seek to evaluate and, if successful, treat
historically abandoned uranium mine waste dumps and recover saleable uranium
and other critical mineral concentrates at Metals One's 100%-owned Uravan Belt
Uranium-Vanadium Project in Colorado ("Uravan Project").

 

The Uravan Project was acquired by Metals One in July 2025. It comprises 59
unpatented mining claims (~490 hectares) situated near the historic Buckhorn
Mine within the renowned Uravan Mineral Belt, a district responsible for more
than 60 million pounds of uranium and 330 million pounds of vanadium
production during the 20th century. Within the Uravan Project there are eight
separate abandoned uranium mine waste dumps suitable for potential recovery.
In September 2025, Metals One announced it had returned grades of up to 41,768
ppm uranium (4.17%) from historic waste material (UV5) from rock chip sample
assays.

 

This agreement expands on the existing relationship with DISA, as detailed in
the announcement on 4 September 2025
(https://www.londonstockexchange.com/news-article/MET1/agreement-to-treat-uranium-waste-dumps-with-disa/17214653)
in connection with the Company's 75% -owned Radium Mountain and Wedding Bell
claims, also in Colorado.

 

Under the agreement with DISA, DISA will now advance this exploration work as
more fully set out below.

 

Highlights:

 

·    Metals One to be paid a Gross Revenue Share of saleable uranium and
other critical mineral concentrates recovered from waste dumps at the Uravan
Project via deployment of DISA's modular mobile plants utilising the patented
High-Pressure Slurry Ablation ("HPSA") system

·    No capex or opex payable by Metals One

·    Metals One to receive a percentage of gross product sale revenue
stream, minus certain post-treatment allowable costs - a sliding scale with a
base rate of 2.5%, through to 4.0% in certain metals pricing environments

·    DISA to be operator of the Uravan Projects and pay all associated
costs of permitting, evaluation, treatment and ongoing remediation

 

Advantages of HPSA:

 

·    The HPSA process treats surface dumps of previously partially mined
and aggregated material

·    In September 2025, DISA became the first company to receive a Service
Providers License (SPL) from the U.S. Nuclear Regulatory Commission (NRC)
providing a regulatory license for DISA to remediate abandoned uranium mine
waste

·    Aside from extracting valuable uranium and critical minerals, the
process delivers significant improvements to the local environment and
watersheds by removing on average 90% of the uranium and radium-226 content
from the waste as evidenced by a treatability study DISA completed with the
U.S. Environmental Protection Agency

·    There is strong US Government support for domestic recovery of
uranium and critical minerals from legacy mine waste. This activity is
directly in line with the recent Secretarial Order from the Department of the
Interior (Order No. 3436: Unlocking Critical and Strategic Minerals from Mine
Waste, Cutting Red Tape, and Restoring American Dominance in Strategic Mineral
Production)

 

Next Steps:

 

·    Characterisation programme with a combination of assay and gamma
probe to determine likely quantities of uranium and other recoverable minerals
present in the waste piles

·    Application and completion of all requisite permits needed to
commence treatment of waste and recovery of payable concentrates using HPSA
technology

·    Future potential sale of metals concentrates and payment of gross
revenue to Metals One

 

Daniel Maling, Managing Director of Metals One, commented:

 

"The Uravan Project sits within one of the United States' most prolifically
mined uranium belts. Assays from Metals One's initial exploration activities
last year indicate the exceptional grades historically mined from within the
project, with multiple samples containing uranium and vanadium at ore-grade
levels.

 

It follows that there is a significant opportunity to apply DISA's
breakthrough process to remediate abandoned uranium mine waste from the
identified sites and recover valuable uranium and critical minerals whilst
improving the environmental legacy from historical mining.

 

We're delighted to expand our relationship with DISA to our other Colorado
uranium project which represents another near-term revenue generation
opportunity with no capex or cost exposure for Metals One.

 

DISA has made strong early progress in advancing its work on the Radium
Mountain and Wedding Bell Claims. Their teams are due to sample various sites
in the coming weeks. They expect to have gamma walkover data by the end of
this month and assay results by end-Q3."
