Beacon Securities Limited ("Beacon") is acting as sole agent in connection with the Offering and the Concurrent Private Placement.

Each NFT Unit will consist of one common share of the Company (an "NFT Share") and one-half of one common share purchase warrant of the Company (each whole common share purchase warrant, a "Warrant"). Each FT Unit will consist of one common share of the Company (a "FT Share") and one-half of one Warrant, each of which shall qualify as a "flow-through share" for the purposes of the Income Tax Act (Canada) (the "Tax Act").

Each Warrant will entitle the holder thereof to acquire one non-flow-through common share of the Company (a "Warrant Share") at a price per Warrant Share of $0.24 for a period beginning 61 days following the Closing Date (as defined below) until the date that is 36 months following the Closing Date.

Subject to compliance with applicable regulatory requirements and in accordance with NI 45-106, (i) the Offered Securities will be offered to purchasers resident in all Provinces of Canada pursuant to the Listed Issuer Financing Exemption, and (ii) the NFT Units issued pursuant to the Concurrent Private Placement will be offered to purchasers resident in all Provinces of Canada pursuant to other applicable prospectus exemptions. The Offered Securities sold pursuant to the Listed Issuer Financing Exemption will not be subject to resale restrictions under applicable Canadian securities laws. The NFT Units issued pursuant to the Concurrent Private Placement will be subject to a statutory hold period of four months and a day from the Closing Date in accordance with Canadian securities laws. The Offering and the Concurrent Private Placement are subject to receipt of all required regulatory approvals, including the approval of the TSX Venture Exchange.

An amount equal to gross proceeds from the sale of the FT Units will be used by the Company to incur eligible "Canadian exploration expenses" that will qualify as "flow-through mining expenditures" as such terms are defined in the Tax Act and a "BC flow-through mining expenditure" for purposes of the Income Tax Act (British Columbia) (the "Qualifying Expenditures") related to the Company's projects in British Columbia, Canada on or before December 31, 2027. All Qualifying Expenditures will be renounced in favour of the subscribers effective December 31, 2026. The net proceeds from the sale of NFT Units from the Offering and the Concurrent Private Placement will also be used for exploration and development at the Company's mineral projects and for working capital and general corporate purposes.

An amended and restated offering document related to the Offering (the "LIFE Offering Document") can be accessed under the Company's profile on SEDAR+ at www.sedarplus.ca and on the Company's website at www.endurometals.com. Prospective investors of the Offered Securities being issued pursuant to the Listed Issuer Financing Exemption should read this LIFE Offering Document before making an investment decision.

The Offering and the Concurrent Private Placement are expected to close on or about May 14, 2026 (the "Closing Date") and are subject to the Company receiving all necessary regulatory approvals, including the approval of the TSX Venture Exchange.
