Pacifica Silver Makes New High-Grade Discovery at Claudia with 3.53 g/t Au and 460 g/t Ag over 2.10 m from Justina Vein

Executive Summary

• Pacifica Silver announced assay results from 11 additional drill holes of its Phase I, 8,000‑m program at the Claudia Silver‑Gold Project in Durango, Mexico.
• A new high‑grade discovery was made in hole 25CLAU059D intersecting 9.01 g/t Au and 1,175 g/t Ag over 0.80 m, confirming the previously undrilled Justina vein extends at least 160 m down‑dip.
• The company plans step‑out drilling (Phase II, 12,000 m) to test lateral continuity of the Justina vein and further target the Central vein, Aguilareña system, and other high‑priority zones.

Key Details

• Hole 25CLAU059D (Justina Vein) – 2.10 m @ 3.53 g/t Au & 460 g/t Ag; within this interval a standout 0.80 m @ 9.01 g/t Au and 1,175 g/t Ag (219‑221 m depth).
• Hole 25CLAU064D (Aguilareña Vein) – 6.00 m @ 1.51 g/t Au & 68 g/t Ag; includes 1.65 m @ 3.34 g/t Au & 211 g/t Ag.
• Hole 25CLAU047D (Aguilareña Vein) – 4.85 m @ 1.09 g/t Au & 25 g/t Ag; includes 0.85 m @ 3.64 g/t Au & 74 g/t Ag.
• Central Vein Extension – Hole 25CLAU055D intersected 1.45 m @ 0.73 g/t Au & 53 g/t Ag, confirming extension ≥50 m down‑dip from historic intercepts.
• Pinolera Trend (Hole 25CLAU060D) – 14.15 m @ 0.58 g/t Au & 24 g/t Ag; includes 2.15 m @ 1.62 g/t Au & 90 g/t Ag and a 3.15 m zone extending Central vein further south.
• Aguilareña‑Tres Reyes System – Multiple holes (047D, 048D, 049D, 061D, 063D, 064D) delineated continuity and down‑dip extensions; notable intercepts include 4.85 m @ 1.09 g/t Au & 25 g/t Ag (047D) and 6.0 m @ 1.51 g/t Au & 68 g/t Ag (064D).
• Guadalupana Vein – Hole 25CLAU056D intersected 3 m of brecciated vein with max 0.12 g/t Au & 6.3 g/t Ag; Hole 25CLAU058D intersected a quartz vein 4.55 m @ 0.74 g/t Au & 36 g/t Ag (including 1.31 g/t Au & 32 g/t Ag over 0.90 m).
• Assay Methodology – Samples processed by ALS Minerals (Hermosillo) and ALS assay lab (North Vancouver) using fire‑assay for Au and ICP‑AES for Ag; QA/QC procedures included CRMs, blanks, and split‑sample protocols.
• Future Work – Phase II 12,000‑m drill program to include step‑out drilling of Justina vein, Central vein intersection with Pinolera trend, and additional targets in the southern zone (e.g., Mina Vieja area).
