Enduro Metals Corp. will: (i) upsize its previously announced commercially reasonable best effort private placement, in which, under the amended terms, the company will issue up to 9,375,000 non-flow-through units of the company at a price of 16 cents per NFT unit and up to 28,643,880 flow-through units of the company sold on a charitable flow-through basis at a price of 22 cents per FT unit for combined gross proceeds of up to $7,801,654 pursuant to Part 5A of National Instrument 45-106 (Prospectus Exemptions), as amended and supplemented by Coordinated Blanket Order 45-935 (Exemptions from Certain Conditions of the Listed Issuer Financing Exemption); and (ii) concurrent with the offering, issue up to 6,562,500 NFT units at the NFT issue price for gross proceeds of up to $1.05-million on a private placement basis pursuant to other applicable exemptions from the prospectus requirements under Canadian securities laws.

Beacon Securities Ltd. 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 and one-half of one common share purchase warrant of the company. Each FT unit will consist of one common share of the company 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).

Each warrant will entitle the holder thereof to acquire one non-flow-through common share of the company at a price per warrant share of 24 cents 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 National Instrument 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 B.C. flow-through mining expenditure for purposes of the Income Tax Act (British Columbia) related to the company's projects in British Columbia, Canada, on or before Dec. 31, 2027. All qualifying expenditures will be renounced in favour of the subscribers effective Dec. 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 can be accessed under the company's profile on SEDAR+ and on the company's website. 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, and are subject to the company receiving all necessary regulatory approvals, including the approval of the TSX Venture Exchange.
