Vancouver, British Columbia--(Newsfile Corp. - June 12, 2026) - CleanTech Vanadium Mining Corp. (TSXV: CTV) (OTCQB: CTVFF)  (" CleanTech " or the "Company ") announces that it has entered into a binding definitive Asset Purchase Agreement (the "APA") with Silver Elephant Mining Corp. (TSX: ELEF) (OTCQB: SILEF) (FSE: 1P2) ("Silver Elephant") dated June 11, 2026 pursuant to which the Company will sell its non-core interest in the Robinson-Lasher zinc-germanium-gallium deposit (the "Robinson-Lasher Project") to Silver Elephant (the "Transaction"). The Robinson-Lasher Project is located in the Illinois-Kentucky Fluorspar District ("IKFD") in Livingston County, Kentucky. CleanTech, through its wholly owned US subsidiary, entered into an option to purchase ("OTP") the Robinson-Lasher Project from an arm's length third-party.

The terms of the OTP are detailed in CleanTech's news release dated August 12, 2025. The Robinson-Lasher Project title will be transferred to Silver Elephant upon CleanTech fulfilling the OTP terms and Silver Elephant fulfilling the Transaction terms. CleanTech's primary focus is developing its fluorspar mineral projects at IKFD.

The Transaction reduces CleanTech's future property cash payments by divesting non-core assets while retaining exposure to the Robinson-Lasher Project through the proposed 9.9% equity ownership of Silver Elephant. The Transaction Terms Subject to the terms and conditions of the APA, Silver Elephant has agreed to acquire the Robinson-Lasher Project from CleanTech in consideration of the following: Silver Elephant issuing 6,300,000 common shares to CleanTech at a deemed price of C$0.13 per share (the "Payment Shares") on closing, resulting in CleanTech holding approximately 9.9% of the issued and outstanding common shares of Silver Elephant on a pro forma basis; and paying aggregate cash consideration of US$1,255,000 in scheduled installments of: US$85,000 on or before September 1, 2026; US$85,000 on or before September 1, 2027; US$85,000 on or before September 1, 2028; and US$1,000,000 on or before September 1, 2029. In addition, Silver Elephant is required to commit a minimum of US$2,000,000 in exploration expenditures at the Robinson-Lasher Project and complete an independent technical report prepared by a qualified person.

Separately, CleanTech and Silver Elephant intend to further explore potential joint development of a multi-purpose processing facility capable of producing both zinc and fluorspar concentrates by receiving and processing mineral feeds from various deposits at IKFD. Completion of the Transaction remains subject to a number of conditions, including receipt of all required approvals under applicable securities laws and stock exchange requirements, including any required approval of the Toronto Stock Exchange and the TSX Venture Exchange, including, as applicable, any required disinterested shareholder approval of each of Silver Elephant and CleanTech.
