Vancouver, British Columbia, August XX, 2025 — CleanTech Vanadium Mining Corp. (“CleanTech” or the “Company”) (TSX-V: CTV, OTCQB: CTVFF) is pleased to announce that, through its 100%-owned subsidiary US Fluorspar LLC (“USF”), it has entered into a binding option-to-purchase agreement (the “OTP”) with an arm’s-length private party (the “Vendor”) to acquire mineral rights to the Kentucky–Illinois Fluorspar Projects, totaling approximately 5,140 acres in Kentucky and Illinois, USA (the “Projects”).
Kentucky–Illinois Fluorspar Projects Summary[1]
The Projects cover approximately 5,140 acres within the Kentucky-Illinois fluorspar district, where Mississippian-age limestones are cut by NW–SE normal faults and locally by dikes related to Hicks Dome. Fluorspar is the principal commodity and accessory sphalerite and galena, occurring in steep fault-fill veins, breccia zones, and localized replacements along favorable beds. Shoots typically thicken at bends, step-overs, relay ramps, and fault–dike intersections, providing predictable structural controls and repeatable targets across the belt.

A historic mineral resource estimate is 1.45 million tons with fluorspar grades ranging between 5% and 44%[3]. The Company has not reviewed or validated the historic data, and caution should be taken as a qualified person has not done sufficient work to classify these historical resource estimates as a current mineral resource and the Company is not treating them as a current mineral resource.
The Robinson–Lasher and Carr properties lie on the district’s western to northern flank and are characterized by steep vein sets and ladder veins where dense fault corridors intersect minor dikes. Mineralization is vein-dominant with pockets of replacement within Ste. Genevieve–St. Louis limestones, and historic workings suggest narrow but locally high-grade shoots focused at structural intersections. These blocks are best tested along jogs and splays of the principal faults.
Pitillo/Pattillo, Big 4, Babb–Barnes, Beard–Jones, Memphis, Franklin, Tabb/Lafayette, Crouch–Simpkins, Travis, Mexico, Marion, Kirk–Tyner–Wring, Eagle–Watson, and Susie Beeler track major district structures around Hicks Dome and the Marion–Hurricane trend. They host robust fluorite veins and small breccia or chimney bodies with local stratabound replacements, showing the greatest continuity along master faults such as Big 4 and Mexico and where cross-faults segment the blocks. Priority targets concentrate at fault bends and splays, relay ramps between parallel strands, carbonate–sandstone contacts, and dike intersections that consistently control thicker, mineable widths.

“Securing an option on this multi-property package in the heart of the Kentucky-Illinois Fluorspar District is a logical follow-on to our recent acquisition of the Campbell Crotser Project,” commented Ron Espell, President of CleanTech Vanadium Mining Corp. “Bringing these properties under the same umbrella as Campbell Crotser positions CleanTech as the leading U.S. developer of fluorspar—an officially designated critical mineral essential to steel, aluminum and battery production.”
Proposed Transaction Summary
Under the OTP, the Vendor agrees to sell to CleanTech, and CleanTech agrees to purchase from the Vendor, the Projects for a total purchase price of US$4,000,000 (the “Purchase Price”), funded as follows (the “Option Money”):
- US$250,000 upon OTP signing;
- US$250,000 on or before September 1, 2026;
- US$250,000 on or before September 1, 2027; and
- US$250,000 on or before September 1, 2028.
CleanTech may purchase the Projects at any time by paying the Vendor the Purchase Price less any Option Money paid as of the exercise date.
Fluorspar Market Overview
According to USGS, China produced over 60% of the world’s fluorspar in 2024[4]. China produced 5.9 million tonnes in 2024, followed by Mexico (1.2 million tonnes) and Mongolia (1.2 million tonnes). The remaining countries combined produced approximately 1 million tonnes.
China has shifted from being a net exporter to a significant importer of fluorspar since 2023, due to rising demand from the booming energy storage system including batteries. Chinese customs data indicate that full-year 2024 fluorspar imports (all grades) rose 32% year-on-year to about 1.30 million tons, with Mongolia supplying roughly 88 % of the tonnage[5]. Over the same period China’s outbound shipments contracted sharply: fluorspar exports fell 35% year-on-year to roughly 245 000 t in 2024, the second annual decline as China prioritized domestic supply.
US Fluorspar price has risen from approximately $300 per tonne in 2020 to over $450 per tonne in 2025.
