Barb Project Update

Gunsynd Plc (AIM: GUN) is pleased to provide an update on the Barb Project in Manitoba, Canada, in which the Company holds a 100% legal and beneficial interest.

The Company confirms that it has received geochemical results in full and submitted a technical assessment report covering the 2025 field programme to the Manitoba Mining Recorders Office. The assessment report covers the Company's 26-day prospecting and rock sampling programme and provides an integrated geological and geochemical interpretation.

The Barb Gold Project is located near the historic mining community of Bissett within the Archean Rice Lake Greenstone Belt, a well-established Manitoban gold district that has produced more than 1.7 million ounces of gold historically. Historical production in the district was primarily from the True North Gold Mine, located approximately 30 km to the east of the Barb Project, and contains a permitted gold processing facility.

2025 Programme Results

The 2025 field programme supports the interpretation that gold mineralisation on the Barb Project is consistent with a structurally controlled orogenic gold system, hosted within quartz-carbonate veins and associated shear zones.

Mineralisation is spatially associated with the Wanipigow Shear Zone, a regionally significant structural corridor known to host gold mineralisation in the Rice Lake Greenstone Belt.

High-grade gold results up to 13.12 g/t were previously announced on 28 October 2025 when initial fire assays were received. Multi-element geochemical results from these samples highlight clear pathfinder element associations, typical of hydrothermal mineralising systems of the Rice Lake Greenstone Belt. High gold values are consistently accompanied by elevated silver, tellurium, and bismuth.

A later batch of rock sample results were received that tested the northernmost part of the property i.e. further from the Wanipigow Shear Zone than the first rock samples and demonstrate a secondary target area (see Schedule A). Whilst no samples produced grades of over 1 g/t Au theycontained elevated pathfinder values in the same samples showing positive correlations to Au mineralisation in the complete dataset indicating an enriched mineralising fluid.

Manitoba Mineral Development Fund Grant

Critical Discoveries has conditionally secured a grant of CAD$105,000 from the Manitoba Mineral Development Fund ("MMDF"), administered by the Manitoba Chamber of Commerce, which will contribute to the planned exploration programme on the Barb Project. The funding is expected to be paid in instalments against work programmes and reporting milestones. Payment of the grant is subject to, among other things, MMDF's approval of the Company's proposal and budget for the exploration programme, and Manitoba's continued agreement to appropriate funding to the MMDF.

Next Steps

Following the 2025 field programme, Gunsynd plans targeted exploration to advance understanding and guide future drilling. A focused diamond drilling programme will test priority quartz veins and shear zones, including structures with elevated gold and sulphide enrichment (Betty, Lilac, Disco, and Oxford structures), along strike extensions, and underexplored structural corridors. While the Company continues the drill permitting process, it will also conduct the following programmes to better refine drill targets:

• A systematic soil survey will identify gold and pathfinder anomalies beyond outcrop, and assess continuity between known mineralised zones.
• Induced Polarization (IP) surveys will map concealed sulphide zones, extend shear zone interpretation at depth, and integrate geophysical anomalies with surface geochemistry to prioritise targets, and;
• Continued prospecting and detailed geological mapping will fill gaps in coverage, providing structural, lithological, and sampling data to improve the geological model and support advanced exploration.

Hamish Harris, Executive Chairman of Gunsynd, commented: "The 2025 field programme on the Barb Project has demonstrated its strong potential for gold mineralisation. As drill permits are secured, the Company will proceed with field programmes designed to significantly improve our understanding of the Barb Project and guide drilling on refined targets."
