Talamore drills high-grade results from Supremo Extension, Coffee Gold 40,000m program

Extension drilling extended mineralization beyond the current pit-limits at depth Infill drilling, including hole 26-SPX-RC003 (1.94 g/t Au over 16.3 m), is targeting resource upgrade and conversion within the pit limits Infill assays are materially higher-grade than the M&I and Inferred resource grade of 1.18 g/t and 1.72 g/t, respectively Vancouver, British Columbia--(Newsfile Corp. - June 17, 2026) - Talamore Mining Corporation (TSXV: TALA) (OTCQB: TALMF) (" Talamore " or the " Company ") is pleased to report results from the first fifteen holes of an ongoing 40,000-metre infill and exploration drilling program at its wholly-owned Coffee Gold project in Canada's Yukon Territory. Drilling is currently targeting the higher-grade Supremo Extension zone (Figures 1 & 2), which currently hosts an Indicated Resource of 2,437 kt at a grade of 1.18 grams per tonne (g/t) gold for a contained 92,000 ounces of gold, and an Inferred Resource of 6,059 kt at a grade of 1.72 g/t gold for a contained 335,000 ounces of gold. The Inferred grade at Supremo Extension is significantly higher than the 1.15 g/t Au grade of the overall Coffee Gold project resource estimate and thus provides a compelling target for converting high-grade ounces to the Indicated category for inclusion in the Feasibility Study currently underway.

Today's release includes assay results from the first fifteen reverse circulation holes totalling 1,961 metres of a planned 25,000 metres of infill drilling at Supremo Extension. A total of 125 drill holes for approximately 16,500 metres have been completed to date this year. Drilling Highlights Highlights of the holes reported here from the Supremo Extension structural system include: 1.94 g/t Au over 16.3 m estimated true width (ETW) in hole 26-SPX-RC003 4.77 g/t Au over 3.8 m ETW in hole 26-SPX-RC008 9.28 g/t Au over 3.0 m ETW in hole 2
