Vancouver, June 22, 2026 - Twenty Mile Metals Inc. (TSXV: MILE) (the "Company") is pleased to announce the TSX Venture Exchange (the "TSXV") has approved the listing of the common shares of the Company ("MILE Shares") on the TSXV. The MILE Shares are expected to commence trading on the TSXV at market open on or about June 24, 2026 under the symbol "MILE".

The Company was formed pursuant to the spin-out of the Twenty Mile project from J2 Metals Inc. ("J2") in connection with the completion of a court-approved plan of arrangement under the Business Corporations Act (British Columbia) (the "Arrangement"), which was completed in accordance with the terms of an arrangement agreement dated October 24, 2025 among the Company and J2.

Pursuant to the Arrangement, 4,928,959 MILE Shares were distributed to the former shareholders of J2 and 71,041 MILE Shares are held by J2 in reserve for issuance to warrantholders of J2 on the effective date of the Arrangement.

As previously announced by J2, prior to the completion of the Arrangement, the Company completed a non-brokered private placement of 5,200,000 subscription receipts (each a "Subscription Receipt") at a price of $0.10 per Subscription Receipt generating gross proceeds of $520,000. No finder's fees were payable in connection with the private placement.

Upon the receipt of conditional approval from the TSXV for the listing of the MILE Shares, each Subscription Receipt was converted into one unit of the Company (each a "Unit").

Each Unit is comprised one MILE Share and one share purchase warrant (each a "Warrant). Each Warrant is exercisable to acquire an additional MILE Share at a price of $0.15 per share until June 8, 2029 provided that if the closing price of the MILE Shares exceeds $0.25 per share for a period of 10 consecutive trading days, the Company may give notice of the acceleration of the term of the Warrants to a period of 30 days following such notice.

A listing application dated June 18, 2026 in respect of the Company has been prepared in accordance with the policies of the TSXV and is available under the Company's profile on SEDAR+ at www.sedarplus.ca.
