CleanTech Vanadium Welcomes DOE US$1 Billion Initiative to Secure American Critical Minerals and Materials Supply Chain

Rhea-AI Summary

CleanTech Vanadium Mining Corp. (OTCQB: CTVFF) welcomes the U.S. Department of Energy's announcement of a nearly $1 billion funding initiative to strengthen domestic critical minerals supply chains. The initiative coincides with the USGS's 2025 List of Critical Minerals, which emphasizes the importance of fluorspar, germanium, gallium, indium, silver, and vanadium.

The company's key assets include the Illinois-Kentucky Fluorspar District (IKFD) projects spanning 8,150 acres, with historical production of 30.3 million tons of raw fluorspar, and the Gibellini vanadium project in Nevada containing 127 million pounds of V2O5 in measured and indicated categories, plus 195 million pounds in inferred resources. The Gibellini project received a positive EIS Record of Decision in October 2023.

Vancouver, British Columbia--(Newsfile Corp. - September 15, 2025) - CleanTech Vanadium Mining Corp. (TSXV: CTV) (OTCQB: CTVFF) ("CleanTech" or the "Company") is pleased to share that the U.S. Department of Energy ("DOE") announced on August 13, 2025 close to US$1 billion in forthcoming funding to strengthen domestic critical-minerals and materials supply chains, with emphasis on critical minerals recovery from mine tailings and other waste streams. In addition, the U.S. Geological Survey ("USGS") released the 2025 List of Critical Minerals, expanding the list to fifty-four commodities and underscoring the importance of fluorspar, germanium, gallium, indium, silver, and vanadium to supply-disruption risk to the U.S. economy and national security.^1,2

CleanTech intends to pursue DOE (and other federal) funding opportunities with an initial focus on the Company's fluorspar and critical-minerals projects spanning more than 8,150 acres in the Illinois-Kentucky Fluorspar District ("IKFD"). The Department of Defense (DOD) is currently funding research work at Hicks Dome project in southern Illinois at IKFD, approximately 3 km from the Company's fluorspar project located in Empire sub-district in Pope County IL. DOD funding includes support for the University of Illinois Urbana-Champaign's Critical Minerals & Materials Center to evaluate the Hicks Dome's rare earth and fluorspar deposit potential and advance process-development studies³.

The IKFD historically produced an estimated 30.3 million tons of raw fluorspar⁴—approximately 90% of total U.S. production during World War II (1939-1945) when national demand for steel was high. A review of the relevant literature indicates that significant mine wastes and tailings remain at the Company's projects and across the IKFD containing fluorspar, germanium, gallium, indium, zinc, lead, and silver. Visible tailings and waste dumps are evident from Company site visits, on Google Maps and LiDAR imagery across the Company's Babb and Tabb projects in the southern part of IKFD. Historical records indicate the Babb Fault System produced approximately 145,335 tons of refined fluorspar grading 38% CaF₂ and 1.5% zinc⁵, while the Tabb Fault System is reported to have produced 2-3 million tons with grade above 30% fluorspar⁶. These production figures suggest substantial tailings and waste materials may remain on site.

Past production at the Babb Fault System and the Tabb Fault System are historic in nature and not indicative of any future potential production or the economic viability of any of the Company's projects in the IKFD.

In addition, the Company's Gibellini vanadium open-pit, heap leach project located in Battle Mountain district in Nevada is estimated to contain 21.3 million tons grading 0.298% V₂O₅ (127 million pounds of vanadium pentoxide) in measured and indicated category, with 31.5 million tons grading 0.31% V₂O₅ (195 million pounds of vanadium pentoxide) in inferred category. The Gibellini project may be fast tracked for federal funding given that the Gibellini pit features a strip ratio of 0.4 to 1, greatly minimizes the mineral extraction cost. The Gibellini project received a positive EIS Record of Decision from the Bureau of Land Management in October 2023. ⁷

DOE US$1 Billion Initiative

The DOE has outlined a multi-track funding effort approaching US$1 billion. Specifically, DOE notices of intent include up to US$500 million from the Office of Manufacturing and Energy Supply Chains ("MESC") for battery-materials processing, manufacturing and recycling; US$250 million from the Office of Fossil Energy and Carbon Management to by-product recovery at domestic industrial facilities; up to US$135 million under MESC for a Rare Earth Elements Demonstration Facility that will test recovery routes from mine tailings and other waste streams; about US$50 million for a Critical Minerals and Materials Accelerator program tied to refining and alloying steps in the magnet and semiconductor chain from The Advanced Materials and Manufacturing Technologies Office; and US$40 million program from The Advanced Research Projects Agency-Energy to recover critical minerals from industrial wastewater.^8,9,10

The U.S. Geological Survey's 2025 List of Critical Minerals

The U.S. Geological Survey's 2025 List of Critical Minerals, released on August 25, 2025, proposes adding potash, silicon, copper, silver, rhenium, and lead while removing arsenic and tellurium. It also formalizes an economic-effects method that ranks minerals by their probability-weighted impact on U.S. gross domestic product under trade-disruption scenarios.

The USGS' 2025 List of Critical Minerals serves as a technical recommendation to the Department of the Interior, and, after interagency review, public comment, and further assessment, the Secretary of the Interior determines and publishes the final list.¹¹

Fluorspar is ranked number 47 by the USGS on probability-weighted GDP impact, with an estimated US$14 million net decrease in U.S. GDP. Fluorspar is categorized as moderate risk and recommended for inclusion in the final list of critical minerals. U.S. fluorspar demand is driven by hydrofluoric acid production for uranium enrichment, battery electrolyte production, semiconductors, refrigerants, fluoropolymers, aluminum, and defense, while domestic supply remains almost non-existent. Therefore, recovering fluorspar from legacy mine tailings is strongly aligned with U.S. supply-chain goals. CleanTech's review of historical records indicates a material inventory of legacy tailings across the IKFD that may host fluorspar, silver, germanium, gallium, and indium, making it a strong candidate for a DOE-focused US$1 billion initiative to remediate tailings and recover critical minerals.¹²

Vanadium is ranked number 23, with an estimated US$92 million net decrease in U.S. GDP. Vanadium is categorized as elevated risk by USGS and recommended for inclusion in the final list of critical minerals. U.S. vanadium consumption is driven by high-strength steel products with an accelerating grid-storage demand via vanadium redox flow batteries. With limited primary domestic production, the DOE plan is to grow U.S. production and processing capacity so that both battery-grade electrolyte feed and ferrovanadium can be sourced at home in the United States. CleanTech's plan to advance U.S. vanadium production and processing through the development of its Gibellini vanadium project is designed to meet that need. ¹³

Germanium and gallium are ranked numbers 7 and 6, respectively, by the USGS, with estimated probability-weighted net decreases in U.S. GDP of US$814 million and US$1.4 billion, and both are categorized high risk and recommended for inclusion in the final list of critical minerals. Germanium and gallium U.S. exposure is especially acute because it is essential to fiber optics, infrared optics, and advanced semiconductors and features extensively in the USGS disruption modeling. Germanium and gallium are present in sphalerite-rich zones of the company's Tabb and Babbs projects' tailings, and, with appropriate processing, they could be recovered to provide a U.S. supply and reduce dependence on imports.¹⁴
