Pacifica Silver Identifies New Extensions to Mineralized Veins at Claudia Silver-Gold Project; Provides Phase I Drill Program Update

Core Insights - Pacifica Silver Corp. has identified new high-priority drill targets at its Claudia Silver-Gold Project in Durango, Mexico, based on assay results showing up to 23.6 g/t Au and 480 g/t Ag from 325 surface rock chip samples collected in 2022 [1][2] - The Phase I drill program commenced on September 22, 2025, with plans to apply for permits to drill the new targets in Q1 2026 [1][2] Exploration Results - Recent assay results confirm that high-grade gold and silver mineralization is more extensive than previously recognized, with mineralization present at surface for at least 1.5 kilometers between historical workings [2] - The highest single sample assay result was 22.7 g/t Au and 480 g/t Ag, indicating potential mineralization extending further south towards the Mina de Oro vein system [2] - A total of 322 surface rock-chip and three mine dump samples were collected in 2022, with approximately 85% from vein outcrops south and east of the Tres Reyes workings [4] Sample Highlights - The top 13 samples (4%) assayed ≥100 g/t Ag, with a maximum of 480 g/t Ag and an average of 257 g/t Ag and 3.59 g/t Au [11] - Across all 325 samples, the average grade was 20 g/t Ag and 0.43 g/t Au [11] Drilling Program Update - The Phase I drilling program is designed to delineate and expand known mineralization, with 647 meters completed across the first three holes as of October 8, 2025 [13][14] - The company plans to add a third drill rig in November 2025 to test the permitted northern zone of the Veta Justina area [14] Project Overview - The Claudia Silver-Gold Project spans 11,876 hectares and encompasses most of the historic El Papantón Mining District, where at least nine small mines operated throughout the 20th century [21] - Only 10% of over 30 kilometers of known veins have been drilled, indicating significant potential for new high-grade discoveries [21]
