Pacifica Silver to Launch 12,000 m Phase II Drill Program at the Claudia Silver-Gold Project

Executive Summary

• Pacifica Silver completed a 7,992 m Phase I drill program (29 holes) with high‑grade intercepts disclosed for two holes and assay results pending on the remaining 19 holes.
• A 12,000 m Phase II drill campaign will start Jan 15 2026 targeting expansion of known high‑grade silver‑gold veins and new priority targets across the Claudia Project.
• Ongoing district‑scale work includes extensive surface mapping (288 ha), LiDAR/drone surveys over ~7,000 ha, and a 27 km induced‑polarization/resistivity geophysical survey to identify additional vein targets.

Key Details

• Phase I Drill Program (completed Dec 28 2025)
• Total depth: 7,992 m in 29 holes.
• Hole 25CLAU037D – 10.5 m @ 2.29 g/t Au & 51 g/t Ag from 113 m (incl. 6.55 m @ 3.38 g/t Au & 74 g/t Ag; 0.60 m @ 20.3 g/t Au & 81 g/t Ag).
• Hole 25CLAU039D – 6.35 m @ 2.94 g/t Au & 313 g/t Ag from 140.8 m (incl. 1.30 m @ 6.4 g/t Au & 1,390 g/t Ag).

• Assay results for the remaining 19 holes are pending; notable intersections include quartz veins and sulfosalt‑bearing veinlets in holes 25CLAU058, 25CLAU062, 25CLAU064.

• Phase II Drill Program (starting Jan 15 2026)

• Planned drilling: ~12,000 m using three rigs.
• Objectives:
  1. Step‑out from high‑grade intercepts on Aguilareña, Guadalupana and Veta Central veins.
  2. Test high‑priority targets at Mark Twain, Veta West, Tres Reyes and Veta Central veins.
  3. Initiate drilling south of the Aguilareña/Guadalupana area (Veta Justina, Mina Vieja, Mina de Oro).

• Priority holes will target expansion of the open Aguilareña North zone (previously intersected in holes 25CLAU037D & 25CLAU039D) and further test Guadalupana vein mineralization.

• Historical Context & Comparative Intercepts

• Prior operator (2021) hole 21CLAU011D intersected 4.05 m @ 10.54 g/t Au & 317 g/t Ag.

• Current Phase I holes have expanded the high‑grade envelope relative to that historic intercept.

• Additional Vein Intersections

• Veta Central: Hole 21CLAU31D (2021) – 6.05 m @ 1.27 g/t Au & 90 g/t Ag; Phase I hole 25CLAU042 – 3.15 m @ 0.85 g/t Au & 43 g/t Ag.

• Mark Twain vein: Hole 25CLAU040D – 1.10 m @ 1.45 g/t Au & 117 g/t Ag (incl. 0.55 m @ 2.79 g/t Au & 201 g/t Ag).

• Surface Exploration & Mapping

• Detailed mapping of an additional 288 ha in the southern project area completed in 2025; continued mapping planned for 2026.

• High‑resolution LiDAR and drone orthophoto surveys covering ~7,000 ha have identified historic workings, vein continuations, and alteration zones.

• Geophysical Survey

• Commenced Jan 10 2026: induced polarization (IP) and resistivity (Res) survey – 27 km of lines to detect chargeability anomalies associated with mineralized veins and uncover new targets east of the Guadalupana vein.

• Qualified Person

• Patrick Loury, AIPG CPG, Exploration Technical Advisor, has reviewed and approved all technical content per NI 43‑101.
