North Vancouver, British Columbia--(Newsfile Corp. - October 23, 2025) - Lion One Metals Limited (TSXV: LIO) (OTCQX: LOMLF) ("Lion One" or the "Company") is pleased to announce that it has closed its previously announced and upsized non-brokered sidecar private placement for gross proceeds of $8,310,245.44 (the "Sidecar Private Placement"). The Sidecar Private Placement was completed in addition to the Company's recently completed non-brokered private placement pursuant to the listed issuer financing exemption available under National Instrument 45-106 - Prospectus Exemptions for aggregate gross proceeds of $25,000,000 (the "LIFE Offering").

Pursuant to the closing of the Sidecar Private Placement, the Company issued an aggregate of 25,969,517 units (the "Offered Units") at a price of $0.32 per Offered Unit (the "Issue Price"). Pursuant to the Sidecar Private Placement and the LIFE Offering, the Company has raised aggregate gross proceeds of $33,632,005.12, representing the issuance of an aggregate of 105,100,016 Offered Units at the Issue Price. Each Offered Unit issued pursuant to the Sidecar Private Placement and the LIFE Offering consisted of one common share of the Company (a "Common Share") and one Common Share purchase warrant (a "Warrant"). Each Warrant will entitle the holder thereof to acquire one Common Share at an exercise price of $0.42 for a period of three years from the date of issuance.

Lion One's CEO Ian Berzins stated: "We're very pleased with the overwhelming demand we received for this upsized LIFE Offering and Sidecar Private Placement. This demand represents a strong vote of confidence in Lion One. With the completion today of the Sidecar Private Placement, we can now accelerate the purchase of several key pieces of underground mobile equipment which will enable us to further increase mine development and production at Tuvatu. We can also ensure the completion of the flotation plant in Q1 2026, which will increase our gold recoveries to over 90%. The Company is well positioned to take advantage of the strong gold price environment and we're very excited for what lies ahead as we continue to ramp up development and production at Tuvatu."

The Company intends to use the net proceeds from the LIFE Offering and the Sidecar Private Placement to fund the development of the Company's 100% owned and fully permitted high grade Tuvatu Gold Project, repayment of principal and interest for the Company's loan facility with Nebari, and for working capital purposes.

In connection with the Sidecar Private Placement, the Company paid aggregate finder's fees of $635,904 in cash and issued 1,987,200 finders warrants (the "Finder's Warrants") to Canaccord Genuity Corp., Ventum Financial Corp., Golden Capital Consulting Ltd. and Hasselbom Forvaltning AB, in accordance with the policies of the TSX Venture Exchange (the "TSX-V") representing a cash commission equal to 8% of the gross proceeds raised from purchasers introduced to the Company by eligible finders and 8% of the aggregate number of Offered Units sold to purchasers introduced to the Company by eligible finders. In lieu of receiving $321,760 in cash, one finder received 1,005,500 Offered Units at the Issue Price, which Offered Units are included in the total number of Offered Units issued pursuant to the Sidecar Private Placement. Each of the Finder's Warrants will entitle the holder to purchase one Common Share at an exercise price of $0.32 per Finder's Warrant exercisable for a period of two years from the date of issuance of such Finder's Warrant.
