Binding Agreement to Treat Uranium Waste Dumps with DISA Technologies

 

Further to the announcement on 4 September 2025 regarding a term sheet with
DISA Technologies, Inc. ("DISA") in respect of Metals One's 75%-owned Radium
Mountain and Wedding Bell uranium claims in Colorado (the "Colorado
Projects"), Metals One (AIM: MET1), a critical and precious metals exploration
and development company, is pleased to provide the following update.

 

Standard Minerals Inc. ("Standard"), the holder of the Colorado Projects and a
75% owned subsidiary of Metals One, has now signed a Binding Agreement (the
"Agreement") with DISA to, as announced before, seek to evaluate and, if
successful, treat historically abandoned uranium mine waste dumps ("waste")
and recover saleable uranium and other critical minerals concentrates at the
Colorado Projects.

 

Highlights:

 

·    Full Binding Agreement whereby Standard is to be paid a Gross Revenue
Share of any saleable uranium and other critical mineral concentrates
recovered from waste at its Colorado Projects via deployment of DISA's modular
mobile plants utilising the patented High-Pressure Slurry Ablation ("HPSA")
system

·    DISA has now received its final U.S. Nuclear Regulatory Commission
("NRC") Service Providers License ("SPL") to remediate abandoned uranium mine
waste

·    No capex or opex payable by Standard

·    13 separate prospective waste dumps have been ground surveyed at the
Colorado Projects - others may be added to this inventory over time

·    Standard 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 will be the operator of the Colorado Projects and pay all
associated costs of economic evaluation, permitting, treatment and ongoing
remediation

·    DISA expects to initiate a detailed site characterisation programme
in 2026 to evaluate resource potential - results will inform the timing and
scope of future uranium recycling activities

 

Dan Maling, Managing Director of Metals One, commented:

 

"Signing this Binding Agreement means that Metals One is on track to go from
waste to potential development at two of our uranium projects within 12-24
months. DISA is in the business of remediating historically abandoned uranium
mine waste dumps, and it is now the first company in the U.S to have received
a Service Providers License for this work from the U.S. Nuclear Regulatory
Commission. We believe their patented HSPA technology makes both economic and
environmental sense, recovering valuable uranium and critical minerals whilst
rehabilitating historic sites."

 

Advantages of HPSA:

 

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

·    DISA has been working with the U.S. NRC since 2021 on a robust
licensing process, which has now concluded, making DISA the first company to
receive an SPL 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

·    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 dumps and economic evaluation scheduled for 2026

·    Application and completion of all requisite local 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 via Standard. Potential revenue cannot yet be quantified
until assay and gamma probe programs are performed
