Tier One Silver Closes First Tranche of Previously Announced Upsized Private Placement

Tier One Silver Inc. (TSXV: TSLV,OTC:TSLVF) (OTCQB: TSLVF) ("Tier One" or the "Company") is pleased to announce that it has completed the first tranche of its previously announced upsized non-brokered private placement (the "Offering") by issuing 41,488,000 units at C$0.08 per unit for gross proceeds to the Company of C$3,319,040. Each Unit consists of one common share (a "Share") and one full common share purchase warrant (each, a "Warrant"). Each Warrant entitles the holder thereof to purchase one common share of the Company at a price of C$0.11 at any time on or before September 11, 2028.

A second and final tranche of the Offering is expected to close on or about September 16, 2025, subject to the receipt of funds and subscription agreements. The proposed use of proceeds from the Offering is to fund exploration at Curibaya, new project investigation and general working capital.

In connection with the closing of the first tranche of the Offering, the Company paid cash finders' fees of C$205,173 and issued 2,564,660 non-transferable finders' warrants. Each finder's warrant is exercisable on the same terms as the unit warrants as noted above. In addition, on the closing of the second and final tranche, the Company intends to pay a corporate finance fee to a registrant who acted as financial advisor and administrator in relation to the Offering.

In accordance with applicable securities laws, the Shares, Warrants and any additional Shares issued on exercise

of the Warrants are subject to a four-month and one day hold period in Canada from the date of issuance, which for the first tranche expires January 12, 2026. The Warrants issued to certain of the investors contain a restriction precluding their exercise to the extent that the holder would as a consequence of exercise exceed 9.99% of issued shares. Accordingly, no new insiders will result from the Offering. Final approval by the TSX Venture Exchange is expected upon filing standard documentation.

The securities issued pursuant to the Offering have not, nor will they be registered under the United States Securities Act of 1933, as amended, and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons in the absence of U.S. registration or an applicable exemption from the U.S. registration requirements. This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in the United States or in any other jurisdiction in which such offer, solicitation or sale would be unlawful.
