Tirzzit Drill Campaign Update

Talisman Metals PLC ("Talisman" or the "Company") provides an update on its ongoing drill program at Tirzzit (see press release of 2 September 2026). As of September 11, 187 meters have been drilled, out of the anticipated 2,770m programme, and the campaign has intersected copper mineralisation by way of visible malachite (a copper-bearing mineral) in the RC drilled material (see Picture 2 and Table 1). The Company plans to send the first batch of samples for assay analysis in the next week, with results available within four to six weeks from then.

Tim McCutcheon, Talisman's CEO stated: "We just started our drill programme, and we are already intersecting visual copper mineralisation within the Tirzzit sediment-hosted deposit. There is still quite a lot of work ahead, but to start off the campaign this way is very satisfying. The team is working smoothly, the pace of drilling is set to accelerate and we look forward to reporting our first assay results as they become available."

About the Tirzzit Project

The Tirzzit Project is a sediment-hosted stratiform Cu-Ag system, located 225km east of the city of Agadir, Morocco. The acquisition transaction of the Project was announced February 16, 2026 (see press release) from a wholly owned subsidiary of Aya Silver & Gold Inc. (TSX: AYA; OTCQX: AYASF) ("Aya"), the Company's 4.7% shareholder. The Tirzzit Project consists of two mining licenses covering a surface area of 16.5km2. Historic drilling results, as reported by Moroccan Government agency Bureau of Research and Mining Participations (BRPM) between 1972 and 1976 ("BRPM Reports"), include drill intersections of 3.16% Cu over 2.5m and 0.60% Cu over 11.4m. Presently the Company is reviewing the extensive BRPM Reports and past collected geophysical data for exploration planning slated to commence in 3Q2026. Talisman continues to process with Aya the formal transfer of the Tirzzit licences on the back of the sale agreement announced February 16, 2026.
