• Significant gold-silver assay results, including 81m at 148gpt AgEq and 44.9m at 259gpt AgEq
• Mineralisation now defined over 425m of strike and 125m of vertical extent, open to southeast and at depth
• Ongoing infill drilling supports higher confidence maiden JORC Mineral Resource Estimate in November 2025

Unico Silver has received assay results for the first two holes (376m) from the recent La Negra SE discovery, within the Company's 100%-owned Joaquin Project in Santa Cruz, Argentina. Significant gold-silver assay results include 81m at 148gpt AgEq (0.9gpt Au, 60gpt Ag) from 39m, and 44.9m at 259gpt AgEq (2.2gpt Au, 49gpt Ag) from 81.1m. Mineralisation is now defined over 425m of strike and 125m of vertical extent and is open to the southeast and at depth. Ongoing infill drilling (24 holes for 3347m) at La Negra supports a higher confidence maiden JORC Mineral Resource Estimate (MRE), which has been deferred to November 2025 to allow inclusion of these results and the expanded footprint. The Company's fully funded 20,000m drill program will next focus on the recently announced La Morocha SE, La Negra Feeder, and Brunilda prospects.

The Company has not provided any high-importance, price-sensitive forward-looking financial metrics in the announcement.

The Company plans to focus the fully funded 20,000m drill program on further follow-up at the La Negra SE discovery, as well as first follow-up drilling of the La Morocha SE, La Negra Feeder, and Brunilda prospects. This drilling is expected to play an important role in future resource growth, supporting the Company's broader PLUS 150 and BEYOND 300 development strategies.
