The June quarter delivered continued drilling success at the 100%-owned Joaquin Project, with high-grade gold–silver intercepts across Breccia Puntudo, La Morocha SE and La Negra SE that extend mineralisation beyond the March 2026 Mineral Resource. With the exploration drill program now complete, the Company has transitioned its focus to Pre-Feasibility Study (PFS) workstreams ahead of a maiden PFS scheduled for late Q3 2026.

During the quarter Unico Silver upgraded its United States quotation from the OTCQB Venture Market to the OTCQX Best Market, and after quarter end, secured a major land position through the acquisition of the La Mata estancia — a significant de-risking milestone for the Joaquin PFS.

June Quarter Highlights

CONTINUED HIGH-GRADE DRILL RESULTS EXTEND JOAQUIN BEYOND THE MARCH 2026 MRE

• Assays reported from 121 drill holes totalling 16,194m during the June quarter, extending gold–silver mineralisation beyond the March 2026 Mineral Resource across multiple prospects.
• Best hole to date at Breccia Puntudo (Quebrada Norte): – JDD228-26:11.25m at 1,301gpt AgEq (15gpt Au, 8gpt Ag) from 127.4m, including 6.8m at 1,934gpt AgEq
  (22gpt Au, 8gpt Ag) from 131.2m
• Best hole to date at La Morocha SE: – JDD276-26: 52.3m at 378gpt AgEq (3.3gpt Au, 100gpt Ag) from 184.8m, including 8.5m at 1,813gpt AgEq (18.3gpt Au, 256gpt Ag) from 223.8m
• Wide zones of oxide gold–silver mineralisation returned in step-out drilling at La Negra SE, up to 250m southeast of the March 2026 Mineral Resource (JDD240-26: 78m at 137gpt AgEq from 91m).
• All reported results sit outside the March 2026 Mineral Resource and remain open at depth and along strike, supporting continued resource growth beyond the maiden PFS.
  CORPORATE & STRATEGIC DEVELOPMENTS
• Upgraded United States quotation from the OTCQB Venture Market to the OTCQX® Best Market (ticker “USLRF”), expanding North American investor access and visibility.
• Binding agreement to acquire a 100% interest in the La Mata estancia (10,172 hectares of strategic freehold land) for total consideration of US$12.0 million.
• The binding agreement secures the Company’s right to acquire land hosting the La Morocha and La Negra Mineral
  Resources, exploration upside, and the preferred locations for key infrastructure (processing plant, Tailings
  Storage Facility and haul roads), representing a major de-risking milestone for the Joaquin PFS.
• The Company remains well funded, with A$55 million of cash and cash equivalents at the end of the June 2026
  quarter.
  EXPLORATION DRILLING COMPLETE — TRANSITION TO PFS WORKSTREAMS
• Total reported assays since drilling commenced in September 2025 now stand at 268 holes for 38,661m.
• Exploration drilling complete for the current program; activity is now focused on PFS workstreams —
  geotechnical drilling, Phase 2 baseline environmental studies, and water-exploration drilling for hydrological
  studies.
• Exploration drilling expected to resume in Q3 2026; maiden PFS scheduled for late Q3 2026.

Managing Director Todd Williams commented:
“The June quarter capped off an excellent period of drilling at Joaquin. Across Breccia Puntudo, La Morocha SE and La Negra SE we have continued to deliver high-grade silver-gold intercepts, including the best holes recorded to date at both Breccia Puntudo and La Morocha SE, with mineralisation extending beyond the March 2026 Mineral Resource and remaining open.
With exploration drilling now complete, our focus has shifted firmly to advancing PFS workstreams (geotechnical, baseline environmental and hydrology) ahead of the maiden PFS scheduled for late Q3 2026.
The upgrade to the OTCQX Best Market further strengthens our profile in North America, one of the world’s largest and most sophisticated markets for precious-metals investors, and the subsequent acquisition of the La Mata estancia secures the land required to develop Joaquin, a significant de-risking step for the project.”
