Tier One Silver Announces $5.6 Million Private Placement

Tier One Silver Inc. (TSXV: TSLV,OTC:TSLVF) (OTCQB: TSLVF) ("Tier One" or the "Company") announces it is conducting a private placement financing to a small group of arm's-length investors which include institutional investors, targeting 70,000,000 units of the Company (each, a "Unit") at an offering price of C$0.08 per Unit (the "Unit Price") for gross proceeds to the Company of approximately C$5.6 million (the "Offering"). Each offered Unit consists of one common share of the Company (a "Share") and one full common share purchase warrant of the Company (each, a "Warrant"). Each Warrant will entitle the holder thereof to purchase one common share of the Company at a price of C$0.11 at any time on or before the date which is 36 months after the closing date of the Offering (the "Closing Date").

The proposed use of proceeds from the Offering is to fund project exploration, new project investigation as well as general working capital.

In accordance with applicable securities laws, the Shares, Warrants and any additional Shares issued on exercise of the Warrants will be subject to a four-month and one day hold period in Canada from the date of closing of the Offering. The Warrants issued to certain of the investors will 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.

Closing of the Offering is anticipated to occur on or about September 8, 2025, subject to the receipt of investor documentation, funds and TSX Venture Exchange ("TSXV") approval. The Company will pay a customary finder's fee in cash and non-transferable broker warrants in compliance with the policies of the TSXV.

The securities offered have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements. This press 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 any State in which such an offer, solicitation or sale would be unlawful.
