T2 Metals files NI 43-101 resource estimate for Sherridon copper-zinc-gold-silver project

Four VMS Deposits Defined from Surface with Mineral Resources Open in All Directions Brownfields Project with Established Infrastructure and First Nations Support Vancouver, British Columbia--(Newsfile Corp. - June 26, 2026) - T2 Metals Corp. (TSXV: TWO) (OTCQB: TWOSF) (FSE: WJ6) ("T2 Metals" or the "Company") is pleased to announce filing of an independent National Instrument 43-101 ("NI 43-101") Technical Report describing the Mineral Resource Estimate ("MRE") for its 100%-owned Sherridon Copper-Gold Zinc-Silver- Project ("Sherridon" or the "Project") in west-central Manitoba (Figure 1). The Technical Report supports the MRE announced in the Company's news release dated May 7, 2026 and can be found on the Company's website and SEDAR+. The MRE encompasses four copper-dominant volcanogenic massive sulphide ("VMS") deposits: Bob, Cold Lake, Lost Lake and Jungle (Tables 1a & 1b) that each begin at surface and remain open at depth.

These deposits, along with the two former mines (Sherritt Gordon East and West) and other massive sulphide bodies, form part of a well-defined mineralized horizon that has been traced for over 25 km of strike length at Sherridon (Figure 2). Mark Saxon, President & CEO of T2 Metals, commented: "The resource modelling contained within this technical report confirms what the T2 Metals team have long understood — that Sherridon is a robust, brownfields, multi-deposit VMS district with scale, grade and room to grow. With the report now on file, our focus shifts to the next phase of work: identifying targets along strike and at depth for each resource, advancing metallurgical and environmental baseline studies, and evaluating a Preliminary Economic Assessment.

I thank Geoffrey Reed, Anders Hogrelius and Bouke van 't Riet for their work, which has validated and utilised a large drill dataset to model these four
