CleanTech clarifies technical disclosure on the El Triunfo

Gold-Antimony Project in Bolivia

Vancouver, British Columbia, April 17, 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 n ine inspected diamond-drill-holes recently

drilled in 2020 and 2022. The assays of the drill h oles 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 re sults 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 Survey 2, global annual antimony production was approximately

83,000 metric tons in 2023. China currently dominat es 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.

Triunfo Project Drillholes Map

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 f ractures and faults that host hydrothermal

mineral deposits.

QA/QC

A Quality Assurance and Quality Control (QA/QC) pro gram consistent with industry standards

was implemented during the various drilling campaigns. The procedure involved cutting the core

in half and sampling one half, with each sample weighing between 6 and 10 kg. All core and other

samples were split, bagged, labeled, and shipped directly to the laboratory.

The laboratory used for analysis was ALS Global, wi th sample preparation protocol PREP-31,

and assays requested for silver (Ag) and 41 elements using the ME-ICP41 method. The remaining

50% of the split sample is securely stored at a ded icated facility. Sample preparation is carried

out at the ALS Global laboratory in Oruro, Bolivia, and the analyses are performed at the ALS

Global laboratories in Peru or Canada.

Standards and blanks were inserted at regular inter vals within each sample batch prior to

shipment to the laboratory. These accounted for between 3% and 5% of the analyzed material,

depending on the phase of the drilling campaign .
