Tier One Silver Commences Phase 2 Drilling at High-Grade Curibaya Project in PeruVancouver, British Columbia--(Newsfile Corp. - February 18, 2026) - Tier One Silver Inc. (TSXV: TSLV) (OTCQB: TSLVF) (FSE: TOV0) ("Tier One" or the "Company") is pleased to announce the commencement of drilling at its Curibaya epithermal silver-gold-copper project in southern Peru, through its wholly owned subsidiary, Magma Minerals S.A.C. San Jose Drilling, a well-established Peruvian drilling contractor, has been engaged to conduct the diamond drill program, the Company's first follow-up program since its successful inaugural drill campaign in 2021. The Phase 2 program will focus on the Cambaya 1 corridor, an undrilled, high-level portion of the epithermal system located more than 250 metres above the areas tested in Phase 1. With the access roads and drill platforms now complete, drilling has commenced from platform 1 to test beneath channel samples 55 and 80 which returned 20 metres (m) of 243 grams per tonne (g/t) silver (Ag) and 0.71 g/t gold (Au), including 7 m of 667 g/t Ag and 1.48 g/t Au, and 4.5 m of 408 g/t Ag and 1.48 g/t Au, including 1 m of 1,768 g/t Ag and 6.33 g/t Au, respectively (see news releases dated October 14, 2021 and September 26, 2022). Peter Dembicki, President, CEO and Director of Tier One Silver, commented, "We are very excited to resume drilling at Curibaya with this Phase 2 program. This campaign marks our first opportunity to drill beneath some of the highest-grade silver mineralization we have uncovered to date through surface channel sampling."He continued, "The Cambaya area represents a compelling, undrilled part of the system which also complements the preferred zonation of the identified epithermal system as indicated by first phase drilling results which improved as we moved towards Cambaya higher up in the system where less erosion has occurred. This program has the potential to significantly advance our understanding of the scale of the system and represents a potential preserved source of the multi kilogram silver samples we have collected from veins in a 20 square kilometer area."The Phase 2 program is designed to test the vertical continuity of high-grade silver-gold mineralization identified through surface mapping and channel sampling, as well as high-resistivity geophysical targets associated with quartz-silica structures (Figure...
