Tier One Silver Secures C$6.5 Million in Oversubscribed Equity Financing to Fuel South American Exploration

VANCOUVER, BC – September 17, 2025 – Tier One Silver Inc. (TSXV: TSLV) (OTCQB: TSLVF) announced today the successful completion of the second and final tranche of its upsized non-brokered private placement, raising a total of approximately C$6.5 million. This financing saw significant investor demand, resulting in an oversubscribed offering that will bolster the company’s exploration efforts in South America, particularly at its flagship Curibaya project.

The final tranche, completed on September 17, 2025, involved the issuance of 39,762,000 units at a price of C$0.08 per unit, generating gross proceeds of C$3,180,960. This follows the first tranche, announced on September 12, 2025, which issued 41,488,000 units at the same price, bringing in C$3,319,040. Combined, the total gross proceeds from the offering reached C$6,500,000. The offering was initially planned for a smaller amount but was upsized due to robust investor interest, reflecting confidence in Tier One Silver’s strategy and project portfolio.

Financing Details and Investor Confidence

Each unit issued in the private placement comprises one common share of the company and one full common share purchase warrant. These warrants provide the holder with the right to acquire an additional common share at an exercise price of C$0.11 for a period of up to 36 months from the date of issuance. Specifically, the warrants from the second tranche expire on September 16, 2028. The participation of institutional investors and existing shareholders underscores a positive outlook for Tier One Silver amidst strengthening precious metals markets, particularly for silver.

Peter Dembicki, President, CEO, and Director of Tier One Silver, expressed his satisfaction with the outcome. “We are very pleased with the strong demand for this financing and the confidence shown by both new strategic investors and our long-standing shareholders,” Dembicki stated. “The oversubscription of this placement reflects not only the robust investor interest in Tier One but also the encouraging momentum we’re seeing in the precious metals markets, particularly silver.” He added that with a stronger balance sheet, the company is well-positioned to advance its exploration initiatives and identify new value-adding opportunities while capitalizing on the improving commodities cycle.

Strategic Use of Funds for Exploration

The proceeds generated from this financing are earmarked for several key strategic areas. A significant portion will be directed towards funding continued exploration at the company’s flagship Curibaya project in Peru, which is known for its high-grade silver, gold, and copper potential. Additionally, funds will support new project investigations, allowing Tier One Silver to explore promising new opportunities in South America, and for general working capital to support ongoing operations.

The Curibaya project, located in a prolific copper porphyry belt in southern Peru, has historically shown impressive mineralization, including high-grade silver and gold intersections. Tier One Silver’s management and technical teams have a proven track record in capital raising, discovery, and monetizing exploration successes, making this financing a critical step in unlocking the project’s full potential.

Regulatory Aspects and Future Outlook

In connection with the closing of the second tranche, Tier One Silver paid aggregate cash finders’ fees of approximately C$168,762 and issued 2,109,520 non-transferable finders’ warrants to Canadian and European-based investment firms. These finders’ warrants are exercisable on the same terms as the unit warrants. In accordance with Canadian securities laws, the common shares and warrants issued are subject to a four-month and one-day hold period, expiring in January 2026 for the first tranche and later for the second tranche. No new insiders will result from this offering, as certain warrants include restrictions to prevent holders from exceeding 9.99% of the company’s issued shares upon exercise.

This successful and oversubscribed financing provides Tier One Silver with the necessary capital to advance its exploration programs and pursue its growth objectives. The company’s focus on discovering world-class silver, gold, and copper deposits, combined with a supportive market environment, positions it for a significant phase of development.
