Pacifica Silver to begin phase II drilling at Claudia

Executive Summary

• Pacifica Silver Corp. announced the completion of its Phase I drill program at the Claudia Silver-Gold Project in Mexico, with 19 assay results still pending.
• The company is launching a 12,000-meter Phase II drill program on January 15, 2026, utilizing three rigs to step out on high-grade intercepts and test new targets.
• Significant high-grade silver-gold intersections were reported from Phase I, including Hole 25CLAU037D (10.5m at 2.29 g/t Au and 51 g/t Ag) and Hole 25CLAU039D (6.35m at 2.94 g/t Au and 313 g/t Ag).
• District-scale exploration is ongoing, including new geological mapping, lidar surveys, and the commencement of an induced polarization (IP/res) geophysical survey on January 10, 2026.

Key Details

• Phase I Program Completion:
  • Total drilled: 7,992 meters across 29 holes.
  • Completed on December 28, 2025.
  • Assay results for the first 10 holes were released; 19 holes remain pending.
• Significant Phase I Intercepts:
  • Hole 25CLAU037D: 10.5 m grading 2.29 g/t Au and 51 g/t Ag from 113.0 m downhole.
    • Included 6.55 m of 3.38 g/t Au and 74 g/t Ag.
    • Included a higher-grade interval of 0.60 m grading 20.3 g/t Au and 81 g/t Ag.
  • Hole 25CLAU039D: 6.35 m grading 2.94 g/t Au and 313 g/t Ag from 140.8 m.
    • Included 1.30 m of 6.4 g/t Au and 1,390 g/t Ag.
  • Other Notable Intersections:
    • Holes 25CLAU058, 25CLAU062, and 25CLAU064 intersected veins containing fine-grained sulphosalt minerals.
    • Hole 25CLAU046D encountered 10.25 m of low-grade stockwork mineralization averaging 0.26 g/t Au and 9 g/t Ag from 248.0 m.
    • Hole 25CLAU042 returned 3.15 m grading 0.85 g/t Au and 43 g/t Ag from 92.4 m.
    • Hole 25CLAU040D intersected the Mark Twain vein with 1.10 m grading 1.45 g/t Au and 117 g/t Ag from 106.4 m (including 0.55 m of 2.79 g/t Au and 201 g/t Ag).
• Phase II Drill Program:
  • Start Date: January 15, 2026.
  • Scope: Approximately 12,000 meters of diamond drilling.
  • Equipment: Three drill rigs.
  • Objectives:
    1. Step out on high-grade intercepts along Aguilarena, 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 Agularena and Guadalupana, focusing on Veta Justina, Mina Vieja, and Mina de Oro areas.
  • Future Outlook: CEO Todd Anthony stated plans to maintain continuous drilling throughout 2026, with potential to increase the program by more than 25,000 meters as results warrant.
• District-Scale Exploration Updates:
  • Mapping: 288 hectares mapped in the southern portion of the project in 2025; mapping to continue throughout 2026.
  • Geophysics:
    • High-resolution lidar and drone-based orthophoto surveys completed covering ~7,000 hectares.
    • Induced polarization and resistivity (IP/res) survey commenced on January 10, 2026.
    • Survey scope: 27 line kilometers (km) planned, contingent on results.
    • Objective: Detect chargeability anomalies associated with mineralized veins and identify new targets east of the Guadalupana vein toward La Concepcion.
• Historical Context:
  • Prior operator hole 21CLAU011D (2021) intersected 4.05 m grading 10.54 g/t Au and 317 g/t Ag from 158.75 to 162.8 m.
  • Prior operator hole 21CLAU31D (2021) intersected 6.05 m grading 1.27 g/t Au and 90 g/t Ag from 62.1 m downhole.
  • Surface samples from the southernmost area showed a high of 22.7 g/t Au and 480 g/t Ag, suggesting mineralization may extend 300 meters toward the Mina de Oro vein system.

Notable Quotes

• "We are excited to kick off our phase II drill campaign following strong initial drill results, which have reinforced our confidence in the scale and quality of the vein systems at our Claudia project," stated Todd Anthony, chief executive officer of Pacifica Silver. "With a substantial number of assays still pending, there is considerable upside yet to be revealed. Our phase II program is designed to systematically step out on high-grade intercepts and to expand our understanding of the broader district-scale potential. Given the extensive vein systems and numerous high-priority targets at the Claudia project, we plan to maintain continuous drilling throughout 2026 and are optimistic about the potential to increase our program by more than 25,000 metres as results warrant."
