Investee Company Update: CleanTech Lithium

 

Laguna Verde 17% Resource Increase Based on Recent Licence Acquisition

 

Metals One (AIM: MET1), a critical and precious metals exploration and
development company, is pleased to note an announcement today by CleanTech
Lithium (AIM: CTL, Frankfurt:T2N) of an updated resource estimate for its
Laguna Verde project following the recent acquisition of additional licences
at the project. Laguna Verde is one of the six salars selected by the Chilean
Government to be prioritised for development by private companies.

 

Metals One owns approximately 10.7% of CleanTech Lithium's issued share
capital.

Highlights

 

·    The mineral resource estimate is updated from that reported on 20 Jan
2025, based on the recent acquisition of additional licences at the project,
as reported to the market on 11 Aug 2025

 

·    The updated total resource is 1.9 million tonnes of Lithium Carbonate
Equivalent (LCE), at a grade of 174 mg/L lithium, a 17% increase from the
previous total resource of 1.63 million tonnes of LCE

 

·    0.84 million tonnes of LCE is in the Measured + Indicated category at
a grade of 178 mg/L lithium

 

·    The additional licences were acquired to meet the Government's
licence area requirement for entering the streamlined process for a Special
Lithium Operating Contract (CEOL)

 

·    The Chilean government is finalising the indigenous community
consultations for Laguna Verde and it is expected that the streamlined process
will be announced shortly afterwards

 

·    The JORC (2012) compliant estimate was calculated by Montgomery &
Associates ("Montgomery´" or "M&A"), a leading hydrogeological consultant
highly experienced in lithium brine resource estimation

 

·    The resource estimate is based on three years of annual exploration
programmes completed by CTL from 2022-2024 including drill progammes, pump
test programmes and geophysics surveys

 

·    Montgomery recommends three additional drillholes in the southwest,
north and northeast to potentially increase the resource

 

·    The Measured and Indicated resource estimate will be used in the
ongoing pre-feasibility study (PFS) which is intended to underpin a maiden
reserve estimate for the Laguna Verde project

 

Daniel Maling, Managing Director of Metals One, commented:

 

"As an investor in CleanTech Lithium, Metals One is very encouraged by the
updated JORC-compliant resource estimate for the Laguna Verde project which
underscores the strength and scale of this asset. With the Pre-Feasibility
Study advancing, this update reinforces our view that Laguna Verde is emerging
as one of Chile's most promising direct lithium extraction (DLE) projects and
a potential key supplier to the growing global EV and battery markets."
