Update on Barb Project

Multi-Element Results Received from Previously Reported High-Grade Gold Grab Samples

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 25 June 2026.

As previously announced, Gunsynd engaged Critical Discoveries to complete the Phase 1 Summer Field Program targeting the Lotus and Betty Shaft areas, comprising grab sampling and mineralization characterisation of the prospects. Following the previously reported high-grade gold assay results, returning up to 489 g/t Au, the Company has now received the multi-element geochemical assay results for the 59 rock samples collected during the program.

The multi-element assay dataset provides valuable geochemical information to assist in the characterisation of the mineralisation and will support ongoing interpretation of the Barb Project. Highlights from the multi-element assay results include:

·    High-grade gold values of up to 489 g/t Au accompanied by elevated pathfinder elements, including 0.462% Bi and 0.254% Te.

·    Copper values of up to 10.5% Cu returned from a mineralised grab sample assaying 15 g/t Au.

·    Arsenic values of up to 18.1% As, reinforcing the robust geochemical signature of the Barb gold system.

·    The multi-element assays identify a robust Au-As-Bi-Te ± Cu geochemical signature, providing additional vectors for future exploration and drill targeting.

The multi-element assay results complement the previously reported gold assays, which returned grades ranging from 0.008-489 g/t Au, including 35 samples assaying above 1 g/t, 23 above 5 g/t and 3 above 100 g/t Au.

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.

·    High-grade gold values are associated with strong pathfinder geochemistry including up to 0.462% Bi and 0.254% Te.

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.

·    High-grade gold mineralisation is associated with elevated copper, silver and arsenic values, including up to 10.5% Cu, 53.9 g/t Ag and 18.1% As.

Hamish Harris, executive director of Gunsynd, commented: "The previously reported exceptional high-grade gold results demonstrated the significant strength of mineralisation at the Barb Project. The multi-element assay results now provide important insight into the geochemical signature of the system, confirming the presence of key pathfinder elements associated with the gold mineralisation. Integrating this data with our geological mapping and structural interpretation will further refine drill targeting as we advance the project toward its next phase of exploration."
