About this update from Tier One Silver, Inc.

Vancouver, British Columbia--(Newsfile Corp. - January 8, 2026) - Tier One Silver Inc. (TSXV: TSLV) (OTCQB: TSLVF) (FSE: TOV0) ("Tier One" or the "Company") is pleased to announce that it has commenced preparations to drill the Cambaya target area of its high-grade Curibaya epithermal silver-gold-copper project located in Tacna, Peru (Figure 1) through its wholly owned Peruvian subsidiary, Magma Minerals S.A.C. The diamond drill program ("Phase 2 Drilling"), which will be the first follow up drilling on the Curibaya project since the Company's successful inaugural drill program was completed in 2021 (see result highlights below), is targeted to be completed in Q1 2026. Phase 2 Drilling is expected to consist of approximately 1,150 metres (m) using one drill rig (Figure 2) first targeting the high-grade silver-gold epithermal mineralization defined at surface in the Cambaya area which has not been drilled to date. Summary of Phase 2 Drilling Plans: Phase 1 Drilling Highlights: Figure 1: Illustrates the position of the Curibaya Project with respect to the large copper porphyry mines in Southern Peru.

The average depth of each hole is anticipated to be between 150 m - 250 m per hole, however, depth will vary based on the progress of each hole. Drilling will commence in the Cambaya 1 corridor, which has not yet been drilled. The Cambaya area is composed of two corridors (Cambaya 1 and Cambaya 2) located in the upper part of the epithermal system believed to be the preferred zonation for the silver mineralization discovered to date and more than 250 m higher in topography than the corridors tested in the 2021 Phase 1 drill program. Extensive surface mapping and channel sampling work to date has identified numerous targets where silver and gold mineralization are exposed in multiple different areas of the Cambaya corridors (Figure 4). The program aims to test the vertical continuity of mineralization underneath high-grade silver gold channel sampling results in the Cambaya area and test high resistivity (>400 ohm-m) ge...
