Update on Barb Project

Gunsynd Plc (AIM: GUN) is pleased to provide an update on the Barb Gold Project in Manitoba, Canada, further to the Company's announcement of 4 June 2026.

As per the announcement on 4 June 2026, Gunsynd engaged Critical Discoveries to complete the Phase 1 Summer Field Program targeting the Lotus and Betty Shaft areas, comprising grab sampling and mineralisation characterisation of the prospects. 59 samples were collected across the two historic showings with grades ranging from 0.008 - 489 g/t. Gold-bearing mineralisation was observed at both locations with 35 samples assaying above 1 g/t, 23 above 5 g/t and 3 above 100 g/t Au.

Rock samples were collected as fist-sized grab samples from locations where mineralisation was observed. Gold assay results are reported as Au (g/t) and were determined by fire assay with gravimetric finish. Multi-element geochemical results are pending.

Lotus Showing Highlights:

• Visible gold observed in 12 samples.
• Grab samples returned values up to 489 g/t Au.
• 5 samples returned values over 80 g/t Au.

Betty Showing Highlights:

• Grab samples returned values up to 27.2 g/t Au.
• 7 samples returned values above 5 g/t Au, including 4 samples exceeding 10 g/t Au.
• Commonly observed polymetallic mineralisation comprising tetrahedrite and chalcopyrite.

Hamish Harris, executive director of Gunsynd, commented: "Our interpretation has consistently been that gold mineralisation at Barb is associated with the Wanipigow Shear Zone, as outlined in our February 2026 disclosure. Today's results are consistent with that geological model and further support our understanding of the property's structural controls. We look forward to integrating these results into our ongoing exploration program."
