Unico Silver (USL) Investor Presentation summary

Strategic vision and growth

• Aims to become a globally significant silver developer with over 300Moz AgEq resources, driven by acquisitions and exploration.

• Achieved a 155% increase in resources since 2H 2024, now totaling 232Moz AgEq.

• Consolidated two major silver districts in Argentina, closing five transactions since Nov 2022 at low discovery costs.

• Focused on pit-constrained, high-value oxide ounces for initial development, with long-lead environmental studies underway.

• Benefiting from strong silver prices and Argentina’s fiscal reforms and incentives.

Resource base and exploration

• Cerro Leon MRE increased to 162Moz AgEq, a 73% rise from May 2023, with mineralisation open at depth and along strike.

• Joaquin Project holds a historical foreign estimate of 74Moz AgEq, with ~30,000m of new drilling supporting a revised MRE.

• Combined global resources stand at 232Moz AgEq, 126Moz Ag, and 605koz Au.

• PLUS 150 strategy targets 123–176Moz AgEq in free-milling, pit-constrained resources, with robust historical metallurgical recoveries.

• BEYOND 300 strategy aims to unlock further value through sulphide resource growth and new discoveries.

Recent discoveries and drilling

• Step-out drilling at La Negra SE and La Morocha SE delivered broad, shallow oxide intercepts, expanding the mineralised footprint.

• Notable intercepts include 90m at 164gpt AgEq and 69m at 177gpt AgEq, with mineralisation open in all directions.

• Over 1.3km of extensions defined at La Negra SE, with several holes exceeding 10,000 GT in grade-thickness.

• First systematic drilling of La Negra SE since consolidation confirms continuity and scale, with visible silver and gold at depth.

• 2025 drill campaign targets 50,000m, the largest since 2011, leveraging all-time high silver prices.
