CleanTech clarifies technical disclosure on the El Triunfo Gold-Antimony Project in Bolivia

news images

Vancouver, British Columbia--(Newsfile Corp. - April 17, 2025) - CleanTech Vanadium Mining Corp. (TSXV: CTV) (OTCQB: CTVFF) ("CleanTech" or the "Company") 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 Survey[2], 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.

About the El Triunfo Project:

CleanTech entered into an Option Assignment Agreement with Silver Elephant Mining Corp. ("Silver Elephant") on April 8, 2025 pursuant to which Silver Elephant proposes to assign its rights to an option agreement dated July 10, 2020 (the "Triunfo Option Agreement") to acquire 100% of the equity interests in the capital of Mururata S.R.L. a commercial society existing pursuant to the laws of Bolivia, which owns certain Bolivian mining rights that comprise the El Triunfo Project to CleanTech in consideration for the payment of CAD 155,000 in cash (the "Transaction").

Closing of the Transaction is subject to the satisfaction of certain conditions precedent thereto including, without limitation, satisfactory completion of due diligence in respect of the Triunfo Project by CleanTech, the receipt of the requisite regulatory and stock exchange approvals by each of Silver Elephant and CleanTech, and the execution of an amendment to the Triunfo Option Agreement in form and substance acceptable to CleanTech. CleanTech paid Silver Elephant a refundable deposit in the amount of $155,000 which deposit shall be repaid in the event the Transaction is not completed by December 31, 2025 or if the Triunfo Option Assignment Agreement is otherwise terminated.

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.

QA/QC

A Quality Assurance and Quality Control (QA/QC) program 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, with 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 dedicated 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 intervals 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.
