CleanTech Highlights Antimony at El Triunfo Project in
Bolivia, Drill Core Assays Up to 1% Antimony
Vancouver, British Columbia, April 14, 2025 — CleanTech Vanadium Mining Corp.
(“CleanTech” or the “Company”) (TSX-V: CTV, OTCQB: CTVFF) is pleased to announce that
it has identified multiple occurrences of antimony in select drill core from the El Triunfo gold and
antimony project (the “Triunfo Project”) located 75 km east of La Paz city, Bolivia.
While conducting due diligence on the Triunfo Project drillhole database, the Company observed
several intervals of antimony mineralization from nine inspected diamond-drill-holes recently
drilled in 2020 and 2022. The assays of the drill holes are tabulated below. All nine drill holes
contained several intersections of antimony grading higher than 0.1%. Hole TR010 contained 1.2-
meter intersection grading over 1% antimony.

The Company is highly encouraged by the antimony results and will continue to evaluate this
potential by reviewing and assaying prior historic drill core. The Company is optimistic about
exploring Triunfo Project’s potential to meet the increasing demand in critical sectors like energy
storage, military and industrial alloy manufacturing.
Antimony price has reached over US$40,000 per ton in 2025 representing over a 250% increase
since January 2024 according to S&P Global 1. This surge follows China's announcement on
January 1, 2025, restricting antimony exports to the United States as part of broader controls on
critical minerals, including antimony, gallium, and germanium.
Antimony is a crucial material in flame retardants, lead-acid batteries, ammunition, and various
metal alloys critical for industrial and defense applications.
According to the U.S. Geological Survey2, global annual antimony production was approximately
83,000 metric tons in 2023. China currently dominates global antimony supply, accounting for
around 50% of total production and most of the world's exports. The United States currently has
no domestic antimony production and relies entirely on imports to meet its antimony requirements.
Bolivia produces approximately 3,000 metric tons of antimony annually, accounting for about
3.6% of global supply according to USGS.

(*) Gold equivalent calculation uses a gold price of $3,107, a zinc price of $1.28, a lead price of
$0.92, and a silver price of $34.26 (all US$), and assumes a 100% metallurgical recovery. Gold
equivalent values can be calculated using the following formula: AuEq g/t = ((Au oz x Au price per
oz + Ag oz x Ag price per oz + Zn lb x Zn price per lb + Pb lb x Pb price per lb) / Au price per oz))
x 31.10
Triunfo Project Historic Drilling Results (drilling performed by Solitario Resources Corp.)
Exploration was conducted in 2005 - 2007 by Solitario Resources Corp., which consisted of 3 drill

(*) Gold equivalent calculation uses a gold price of $3,107, a zinc price of $1.28, a lead price of
$0.92, and a silver price of $34.26 (all US$), and assumes a 100% metallurgical recovery. Gold
equivalent values can be calculated using the following formula: AuEq g/t = ((Au oz x Au price per
oz + Ag oz x Ag price per oz + Zn lb x Zn price per lb + Pb lb x Pb price per lb) / Au price per oz))

Location & Geology
The Triunfo Project lies within Bolivia’s Cordillera Real, an area with complex geology including
Paleozoic metamorphic and igneous formations. This region has experienced multiple tectonic
and orogenic (mountain-building) events, creating fractures and faults that host hydrothermal
mineral deposits. Below information is based on the publications from Bolivian Mining Ministry,
COMIBOL reports, International Mining Company S.A. reports and Company estimates.
Nearby Gold Mineralized Zones
Illimani Zone (Located 11 kilometers southeast of Triunfo Project): Hosts quartz veins located
above 5,000 meters. Active cooperatives and Chinese companies operate in the area.
Palca Zone (Located 11.6 km west of Triunfo Project): Features ancient mine workings (dating
to the Spanish era) in Ordovician-Silurian metamorphic rocks. Currently, only small-scale alluvial
operations continue in the main valley.
Incachaca Zone (Located 27 kilometers to the northwest from Triunfo Project): Known for gold
with associated lead, zinc, and copper mineralization. Cooperatives actively work Ordovician-
Silurian host rocks, similar to those at Triunfo Project.
Alluvial Gold Deposits
Two active alluvial gold-producing areas lie in the lower valley draining from Illimani. Local mining
cooperatives operate these deposits.
Antimony Mineralized Zones
Several old properties (Located 4 - 5 kilometers southwest of Triunfo Project): These antimony
mines produced antimony from Paleozoic rocks.
Wolfram Mineralized Zones
Bolsa Negra Zone (Located 5 km east of the Triunfo Project): Contains quartz veins with wolfram,
tin, lead, zinc, and minor gold in Ordovician-Silurian rocks.
La Chojlla Mine (Located north of Triunfo Project, at a distance of 17 kilometers): The mine
produces tin, wolfram, lead, and zinc. Mineralization is in granite intrusions cutting Ordovician
rocks.
QA/QC
An industry standard Quality Assurance/Quality Control program was used during the various drill
campaigns. All core and other samples were split with half being bagged, labelled and shipped
directly to the laboratory. The other 50% split is retained in a secure facility. Both standards and
blanks were inserted at regular intervals within each sample batch prior to shipment to the
laboratory. These comprised 3-5% (depending on the phase of the drill campaign) of analyzed
material.

reflects management’s expectations regarding CleanTech’s future growth, results of operations,
performance, business prospects and opportunities, is based on certain factors and assumptions
and involves known and unknown risks and uncertainties which may cause the actual results,
performance, or achievements to be materially different from future results, performance, or
achievements expressed or implied by such forward-looking information. Forward-looking
information in this news releases includes: the forward looking market data relating to
antimony,that all conditions precedent to the Transaction will be met and the realization of the
anticipated benefits derived therefrom for shareholders of each of CleanTech and perception of
(i) the quality and the potential of the El Triunfo Project, (ii) the consideration offered by CleanTech
for the El Triunfo Project, and (iii) the potential of CleanTech’s businesses following completion of
the Transaction. Forward-looking statements are based on the opinions and estimates of
management of CleanTech at the date the statements are made and are based on a number of
assumptions and subject to a variety of risks and uncertainties and other factors that could cause
actual events or results to differ materially from those projected in the forward-looking statements.
Many of these assumptions are based on factors and events that are not within the control of
CleanTech, there is no assurance they will prove to be correct and are not guarantees of future
performance and actual results may differ materially from those in the forward-looking statements.
