March 2026 Quarterly Activities & Cashflow Reports

• Maiden JORC Mineral Resource of 45.3Mt at 115gpt AgEq for 167Moz AgEq at Joaquin
• Continued strong drill results across Joaquin, including high-grade intercepts at Breccia Puntudo
• Ongoing PFS workstreams including environmental studies and metallurgical test work

Unico Silver has delivered a maiden JORC Mineral Resource of 45.3Mt at 115gpt AgEq for 167Moz AgEq at its Joaquin project, representing a 143% increase in contained AgEq since acquisition in October 2024. The updated MRE incorporates 27,723 metres of additional drilling and growth from 5 prospects, including La Negra, La Morocha and Breccia Puntudo. The Joaquin MRE includes 123Moz Ag and 521koz Au, confirming it as a unique silver dominant system. Drilling during the quarter continued to deliver strong results, with high-grade intercepts from Breccia Puntudo confirming a new mineralised corridor. Ongoing PFS workstreams include baseline environmental studies, engineering trade-off studies, comminution and metallurgical test work, and tailings storage facility design. The company has also strengthened its board and executive team to support the development phase, implemented a long-term incentive framework, and commenced trading on the OTCQB Venture Market in the United States.

Unico Silver is well-positioned to advance its Joaquin project through the feasibility study phase, with a globally significant 167Moz AgEq resource and a clear pathway to development in Argentina.
