T2 Metals commences first-ever surface diamond drill program at Shanghai

Program Underway to Test High-Grade Keno Hill-style Silver-Lead-Zinc and AurMac-style Gold-Silver Targets

Vancouver, British Columbia--(Newsfile Corp. - September 16, 2026) - T2 Metals Corp. (TSXV: TWO) (OTCQB: TWOSF) (FSE: WJ6) ("T2 Metals" or the "Company") is pleased to announce that surface diamond drilling has commenced at the Company's Shanghai Silver-Gold Project (" Shanghai " or the " Project ") in central Yukon, Canada. This first-ever surface drill program at Shanghai marks a major operational milestone as the Company continues to advance its exploration activities in the Yukon.

Project Location

Shanghai is located in the Mayo Mining District within the Tombstone Gold Belt, one of North America's most prolific silver and gold mining regions (Figure 1) and is surrounded by multi-million-ounce deposits (Figure 2, Table 1).

The Project shares key geological characteristics with Hecla Mining's Keno Hill District (" Keno Hill "), one of the world's highest-grade silver districts, located 6 km to the southeast. Shanghai also shares significant geological characteristics with Banyan Gold's AurMac Project (" AurMac "), one of Canada's largest unmined gold deposits, located 6 km to the south, and the Eagle Gold Mine, the largest gold mine ever built in the territory, located 12 km to the northwest.

Two Distinct Styles of Mineralization

The Project holds potential for two distinct styles of mineralization: high-grade vein deposits rich in silver, lead and zinc, as well as a Reduced Intrusion-Related Gold System (" RIRGS "), a deposit style typically characterized by large-scale, bulk-tonnage gold. This geological setting is influenced by two major regional structures: the McQuesten Antiform and the Robert Service Thrust fault system (Figure 2), which have played an important role in the distribution of mineralization across the Mayo Mining District.
