Unico Silver (USL) investor relations material

Strategic vision and development pathway

• Advancing toward production with a globally significant silver resource of 330 Moz AgEq across two 100%-owned districts in Santa Cruz, Argentina, with a maiden pre-feasibility study (PFS) due January 2027.

• Development strategy focuses on an oxide-led, open-pit, free-milling starter operation, with future polymetallic sulphide expansion at Cerro Leon.

• Over 68,000 meters drilled since Q4 2024, with an additional 30,000 meters planned for 2026 to support resource growth and conversion.

• Binding agreement to acquire 10,172 ha of freehold land for mine development, with granted mining leases and a clear path to full mining approvals.

• Application for Argentina’s RIGI regime with the PFS, targeting 25% corporate tax and 30-year fiscal stability.

Resource scale, growth, and project details

• Combined resources at Joaquin (167 Moz AgEq) and Cerro Leon (162 Moz AgEq), both open at depth and along strike, underpinning the PFS.

• Resource growth of 3.5x since May 2023, with mineralisation confirmed by high-grade drill intercepts and ongoing exploration.

• Operational synergies assessed by co-developing both projects, including hauling high-grade Cerro Leon oxide to the Joaquin processing facility.

• Santa Cruz province hosts 397 Moz Ag across 11 projects, with Joaquin and Cerro Leon holding 47% of contained silver.

• Historical metallurgical testwork supports whole-ore cyanidation with ~80-85% recoveries for oxide resources.

Financials, market context, and permitting

• Market capitalisation of A$507M and cash balance of A$55M as of June 2026, with 642M shares on issue.

• Silver market in multi-year deficit, with above-ground stocks drawn down and strong demand from solar, EV, and data centers.

• Santa Cruz offers a proven, predictable permitting pathway, with 10 gold-silver operations permitted since 1996 and no exploitation-stage refusals.

• RIGI regime locks in 30 years of tax, customs, and FX stability, with Unico targeting approval in 1H 2027.

• Board and management have a strong track record in discovery, finance, and development of world-class mining projects.
