Pacifica Silver plans phase I drilling at Claudia

Executive Summary

• Pacifica Silver Corp. announced its Fall 2025 exploration program at the wholly owned Claudia Silver-Gold Project in Durango, Mexico.
• The program includes an initial 8,000-meter Phase I drill campaign scheduled to commence at the end of September 2025, alongside a property-wide surface exploration initiative.
• The drilling aims to expand known high-grade silver-gold mineralization along the Aguilarena, Guadalupana, and Veta Central veins, and test new targets including Mark Twain, Veta West, and VCE.

Key Details

• Drilling Program Scope: An 8,000-meter Phase I drill campaign is planned to start at the end of September 2025.
• Previous High-Grade Intercepts (2021 Durango Gold Drilling):
  • Hole 21CLAU011D: 9.15 m at 688 g/t AgEq (from 157.75 m), including 3.15 m at 1,352 g/t AgEq.
  • Hole 21CLAU34D: 4.15 m at 554 g/t AgEq (from 140.8 m), including 0.55 m at 1,955 g/t AgEq.
  • Hole 21CLAU31D: 6.05 m at 192 g/t AgEq (from 62.1 m), including 1.0 m at 437 g/t AgEq.
  • Note: AgEq calculated using an 80:1 silver-to-gold ratio.
• New Drill Targets:
  • Mark Twain Vein: Silver-rich target known from historical underground sampling in the early 1990s.
  • Veta West: Prioritized due to strongly anomalous silver-gold values in previous surface rock chip sampling; drilling near the intersection with the Aguilarena and Mark Twain veins.
  • VCE Structural Intersection: Targeting the intersection between a north-south-striking vein and an east-west-striking vein.
• Property-Wide Exploration:
  • Detailed geological mapping and systematic surface sampling to enhance understanding of the mineralized system.
  • Focus on historical mine workings at La Concepcion, Providencia, and Mina de Oro/Mina Vieja.
• Geophysical Survey: A 27 line-kilometer Induced Polarization (IP) and resistivity survey is planned for Q4 2025 to identify chargeability features related to mineralized veins.
• Technical Personnel: Patrick Loury, AIPG, CPG, serves as the exploration technical adviser and Qualified Person under National Instrument 43-101.
• QA/QC Details: 2021 samples were processed at ALS Minerals laboratory in Zacatecas, Mexico, and assayed in North Vancouver, Canada, and Vientiane, Laos. Gold analyzed by fire assay with AA finish; Silver by ICP-AES.

Notable Quotes

• "Pacifica Silver is poised to embark on one of the most significant exploration efforts in the Claudia project's history," stated Todd Anthony, chief executive officer of Pacifica. "Drilling in 2007 and 2021 by previous operators confirmed high-grade silver-gold mineralization near historical mine workings over approximately two km of strike along the Aguilarena vein, part of the adjacent Guadalupana vein, and the Veta Central vein. Our upcoming phase I drill program aims to expand upon these zones of known high-grade mineralization and test previously undrilled, high-priority targets."
