Talon Commences Phase 1 Exploration Programme at Eagle Lake Gold Project

Field activities begin today, targeting multiple gold zones ahead of planned Q4 drilling

Talon Resources plc (AIM: TAR), the North American gold exploration company, is pleased to announce that its Phase 1 exploration programme is commencing today at the Eagle Lake gold project ("Eagle Lake" or the "Project"), a highly prospective and underexplored gold project within the Wabigoon Subprovince in Ontario, Canada.

OVERVIEW

·    Critical Discoveries appointed to advance exploration at Eagle Lake

·   Phase 1 field programme commencing today to validate and expand multiple high-grade gold targets, including historical surface assays of up to 204 g/t Au

·    Results to support drill target generation ahead of a planned Q4 2026 maiden drilling campaign

·    Initial 2,000 metre drilling programme planned in two c.1,000 metre phases

Alex King, Talon CEO, commented: "We are delighted to hit the ground running following our admission to AIM, with our immediate focus on advancing the Project towards drilling. Eagle Lake has already returned encouraging high-grade gold results at surface, including assays of up to 204 g/t gold, yet remains relatively underexplored with only limited historical drilling completed.

"Through this programme, we aim to enhance our understanding of the known mineralised zones, refine and prioritise drill targets and identify additional opportunities across the property ahead of our initial drilling campaign later in the year. We look forward to updating shareholders as exploration progresses and results become available."

DETAILS

Eagle Lake comprises 95 contiguous mining claims covering approximately 1,986 hectares within Ontario's prospective Wabigoon Subprovince. Historical exploration has identified multiple gold-bearing zones across the property, including surface sampling results of up to 204 g/t gold. While historical work has demonstrated the presence of gold mineralisation across several zones, exploration has been relatively limited and the Project remains underexplored.

The Company has engaged Canadian geological consultancy Critical Discoveries to advance exploration at Eagle Lake. Activities will include submission of an Early Exploration Plan to the Ontario Ministry of Mines, ongoing consultation and engagement with Eagle Lake First Nation, claim maintenance and execution of the Company's planned field programmes.

The Phase 1 programme, commencing today, will focus on detailed channel sampling of mineralised outcrops, trenches and bedrock exposures, alongside systematic prospecting across eight target areas on the property. Results from the programme will be integrated with historical exploration data to prioritise drill targets ahead of follow-up field work in Q3 2026 and the commencement of drilling in Q4.

The Company intends to complete an initial 2,000 metre drilling programme in two phases of approximately 1,000 metres each, enabling results from the first phase to inform targeting and planning for the second while supporting efficient capital allocation.

Further updates will be provided as exploration progresses.
