Talamore Mining updates mineral resource for Cristina Project, Mexico

Vancouver, British Columbia--(Newsfile Corp. - June 30, 2026) - Talamore Mining Corporation (TSXV: TALA) (OTCQB: TALMF) (" Talamore " or the " Company ") is pleased to report the results of a mineral resource estimate (" MRE ") update at its wholly-owned Cristina polymetallic vein project (the " Project " or " Cristina ") in southwestern Chihuahua State, Mexico. The Project lies within the prolific Sierra Madre gold-silver belt in the state of Chihuahua, Mexico. It consists of multiple outcropping quartz veins, stockwork veins, and breccias that are frequently greater than 10 metres in width and extend for a currently known strike length of up to 5 km.

At least four parallel mineralized vein systems have been mapped to date; however, most of the resource estimate reported in this release is contained within the Guadalupe vein (Figures 1-3), which has been the primary focus of drilling completed on the Project. These results reflect drilling up to April 1, 2025. The MRE was prepared under the supervision of John Sims CPG (an Independent Qualified Person), President of Sims Resources LLC.

Highlights Indicated resources of 17.5 Mt at 0.58 g/t gold, 33.29 g/t silver, 0.50% zinc, 0.18% lead and 0.04% copper (1.41 g/t gold-equivalent ("AuEq") grade), for a contained 795,000 AuEq ounces. A 6% increase in contained AuEq ounces, and a 4% increase in AuEq grade from the 2023 MRE. Inferred resources of 33.0 Mt at 0.50 g/t gold, 23.76 g/t silver, 0.50% zinc, 0.18% lead and 0.05% copper (1.17 g/t AuEq grade), for a contained 1,243,000 AuEq ounces.

A 62% increase in contained AuEq ounces, and a 12% decrease in AuEq grade from the 2023 MRE. The bulk of the resource comes from the Guadalupe vein system, which is just one of the four major vein systems on the property that have been tested by drilling to date. All of the vein systems remain open at depth and along strike, with strong pote
