CleanTech Acquires 970 Acres of Mineral Rights

Nearby Hicks Dome Rare Earth and Fluorspar Project

in the Illinois–Kentucky Fluorspar District

Vancouver, British Columbia, August 29 , 2025 — CleanTech Vanadium Mining Corp.

(“CleanTech” or the “Company”) (TSX-V: CTV, OTCQB: CTVFF) is pleased to announce that,

through its 100%-owned subsidiary, it has entered into a binding option-to-purchase agreement

(the “OTP”) with an arm’s-length private party (the “Vendor”) to acquire a package of highly

prospective mineral rights (“Pope Fluorspar Properties”) near Hicks Dome deposit in Pope county

in southern Illinois. Pope Fluorspar Properties cons ist of 15 mineral rights parcels (each one a

“Property”) totaling 970 acres across Empire S ubdistrict, Stewart Subdistrict and Hobbs Creek

Subdistrict. Those Properties are strategically positioned along the major fault systems that

historically controlled mineralization throughout the approximately 1,000-square-mile Illinois-

Kentucky Fluorspar District (“IKFD”).

Transaction Summary

Under the OTP executed on August 26, 2025, the Vendor agreed to sell to CleanTech, the Pope

Fluorspar Properties for a total of US$184,000 (the “Purchase Price”), consisting of:

• US$29,100 upon OTP signing (paid);

• US$42,680 on or before September 1, 2026;

• US$54,320 on or before September 1, 2027;

• US$57,900 on or before September 1, 2028.

Empire Subdistrict: Home to Illinois' Premium Quality Fluorite

CleanTech's Empire Properties are adjacent to the historic Gaskin Mine, located less than three

miles west of Hicks Dome, which is estimated to contain Fluorspar 1 and additional Rare Earth

Element historical resources. The Gaskin operation stands as a testament to the Empire

subdistrict's extraordinary mineral wealth, having produced approximately 179,000 raw tons from

two parallel veins averaging 5 feet wide, with bedding replacement mineralized zones extending

35 feet in width2.

The Gaskin Mine's reputation for producing some of the highest-grade and gemstone-quality

fluorite in Illinois stems from its unique geological se tting. According to ISGS Circular 604, the

mine's fluorite crystals contained small amounts of rare earth elements (REE) likely derived from

2 http://library.isgs.illinois.edu/Pubs/pdfs/circulars/c604.pdf

the adjacent Hicks Dome, creating distinctively colored pink cubic fluorite crystals with beautiful

phantoms that are "instantly visually recognizable to the avid fluorite collector". Mining operations

extended through multiple working levels at depths of 200, 300, 400, 425, 450, and 475 feet, with

mineralized material present from the base of the Bethel Sandstone down into the Ste. Genevieve

Limestone3,4.

The Empire Subdistrict's mineralized veins appear predominantly along normal faults with

northeast to east-northeast strikes, potentially representing radial fractures created by the vertical

uplift at Hicks Dome or related to extensional forces that created the Dixon Springs Graben5,6.

The Qualified Person has been unable to verify the above information and that information is not

necessarily indicative to the mineralization on the Pope Fluorspar Properties.

Stewart Subdistrict: The Barnett Complex Legacy

The Stewart Subdistrict, where CleanTech now holds significant mineral rights, hosted some of

the IKFD’s most productive and deepest mining operations. The Barnett Mine complex, located

0.6 miles from CleanTech’s Stewart Properties and situated along the same fault, operating from

approximately 1950 to 1983, achieved notable production through shrinkage stoping methods on

the West and Barnett veins. The operation reached a total depth of 240 meters (787 feet) and

maintained working levels that accessing veins 7 to 8 feet wide composed of coarsely crystalline

calcite containing blocks of country rock and pockets of fluorite, galena, and sphalerite7.

Mining records indicate the Barnett complex produced an estimated 550,000 tons, while Ozark-

Mahoning resource calculations from 1981 estimated historical Fluorspar resource exceeding

600,000 tons composed of 40% Barite and 20% Calcium Fluoride (CaF₂ሻ on CleanTech’s Stewart

Properties. The Parkinson and Stockton mines, also located within the same subdistrict

contributed additional production from underground workings targeting barite, calcite, fluorite, and

sphalerite mineralization8,9.

The key assumptions, parameters, and methods used to prepare this historical resource estimate

are not available. The Company has not reviewed or validated the historic data, and caution

should be taken as a qualified person has not conducted 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 historic resource does not demonstrate economic viability and

should not be relied on. The Company considers the historical estimate relevant as it indicates

significant Fluorspar mineralization within the pr oject area; however, the reliability is uncertain

given the age of the data, and differences between historical estimation methods and current

Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards. The

historical resource categories were defined prior to the adoption of current CIM Definition

Standards and differ materially from current categories such as ‘Inferred Mineral Resource.’ The

historical estimates do not meet current CIM requirements for mineral resource classification due

to: insufficient verification, lack of docu mented estimation methodology, and absence of QA/QC

protocols. Steps to verify and upgrade the historical estimates to current CIM standards include

(i) compilation and validation of all historical drill data, (ii) twin drilling of select historical holes, (iii)

confirmatory drilling in key areas of mineralization, (iv) updated geological modeling, and (v)

preparation of a new mineral resource estimate in accordance with NI 43-101.

Hobbs Creek Subdistrict: The Henson Mine Achievement

The Henson Mine within CleanTech's Hobbs Creek Properties represents one of the IKFD’s most

successful and technically challenging operations 10 . Operating during the 1980s, this mine

reached a depth of 950 feet to access the Hobbs Creek Vein along a normal fault striking

northeast and dipping steeply northwest. The operation extracted 112,000 raw tons of white and

purple fluorite hosted in breccia zones of sandstone and shale fragments. The mine's success

demonstrated the continued viability of deep vein mining in the IKFD, even as easier surface

deposits were being exhausted11.

Illinois-Kentucky Fluorspar District: America’s Source of Fluorspar

The Illinois-Kentucky Fluorspar District extraordinary productivity stems from its unique geological

architecture12 . The IKFD sits within Mississippian-age limestones intersected by northwest-

southeast trending normal faults, creating the perfect structural environment for fluorite

mineralization. These steep fault-fill veins, breccia zones, and localized carbonate replacements

developed along favorable limestone horizons, with mineralized material shoots typically

thickening at structural complexities such as fault bends, step-overs, and fault-dike

intersections13,14,15,16.

The geological complexity that made the IKFD America's fluorite capital remains intact.

mineralization occur in four primary deposit types: horizontal bedding replacement deposits, veins

along vertical faults and fractures, residual gravel deposits, and fluorite breccia. This diversity

offers multiple exploration and development targets across CleanTech's extensive land position

of over 8,150 acres17

The IKFD’s strategic importance extends beyond its historical production record. Its established

transportation infrastructure, proximity to industrial consumers, and documented production of

over 32.5 million tons position it as America' s most viable domestic Fluorspar source in an

increasingly import-dependent market. Currently, nearly all Fluorspar consumed in the United

States is imported, with Mexico supplying 72% of 2017 imports, followed by China and South

Africa18,19,20. Fluorspar prices have increased dramatically from $300 per ton in 2020 to over $470

per ton in 202521. China, which accounts for 60% of global Fluorspar production, has become a

net importer of Fluorspar since 2023

Ron Espell, CleanTech’s President Comments:

“With Fluorspar designated as critical for applications in nuclear power, lithium batteries, and

semiconductors, CleanTech's Fluorspar projects represent more than an attractive mining

investment—they are key to America's mineral independence.

CleanTech has positioned itself at the epicenter of America's potential fluorite renaissance.

CleanTech’s land holding now exceeds 8,150 acres with over 730 historic drill holes, in the Illinois-

Kentucky Fluorspar District which once supplied over 90% of U.S. Fluorspar production from

approximately 1914 to 199522.

CleanTech is looking forward to partnering with America’s industrial Fluorspar users and federal

agencies to accelerate the development of IKFD and re-write a new chapter in American

Fluorspar mining history.”
