(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - April 14, 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 Global¹. 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 holes TR-001, TR-002 and TR-003. All drillholes drilled by Solitario Resources Corp. intercepted gold and silver mineralization as shown in the table below.

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.
