Talamore Reports High Grade Assays from Supremo Extension

Infill drilling, including hole 26-SPX-RC105 (12.24 g/t Au over 6.4 m) and 26-SPX-RC199 (6.26 g/t Au over 10.2 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. - September 8, 2026) - Talamore Mining Corporation (TSX: TALA) (OTCQB: TALMF) (" Talamore " or the " Company ") is pleased to report results from 30 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 presently 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 30 reverse circulation holes totalling 4,356 metres of a planned 25,000 metres of infill drilling at Supremo Extension. A total of 223 drill holes for approximately 32,852 metres have been completed through July of this year, with results for 100 holes comprising 13,764 metres released to date.
