Joaquin MRE increases to 167 Moz AgEq

• Significant growth in Joaquin Mineral Resources to 45.3Mt at 115gpt silver equivalent (AgEq) for 167Moz AgEq
• 78% in high-confidence Indicated category, providing a strong foundation for the upcoming Pre-Feasibility Study
• Total free-milling resources now stands at 53.4Mt at 124gpt AgEq for 212Moz AgEq

Unico Silver Limited (USL) is pleased to announce a JORC (2012) Mineral Resource Estimate (MRE) for the Company's 100%-owned Joaquin Project in Santa Cruz, Argentina. The Joaquin MRE now stands at 45.3Mt at 115gpt silver equivalent (AgEq) for 167Moz AgEq, representing a 143% increase in contained AgEq since acquisition of the Joaquin project in October 2024. The updated MRE is underpinned by 27,723 m of drilling completed since April 2025 with an all-in discovery cost of USD 11c per AgEq ounce. Importantly, 78% of the resource is in the high-confidence Indicated category, providing a strong foundation for the upcoming Pre-Feasibility Study. At the district level, the combined resources at Joaquin and Cerro Leon now total 76.2 Mt at 135gpt AgEq for 330Moz AgEq, confirming the projects as a significant undeveloped silver resource globally. The Company's 'Oxide First' development strategy is supported by 53.4Mt at 124gpt AgEq for 212Moz AgEq of free-milling resources, which are amenable to conventional open-pit mining and whole-ore cyanidation processing.

With a clear pathway toward development and significant exploration upside remaining across the district, Unico Silver is uniquely positioned to unlock substantial long-term value from the Joaquin silver district.
