Pacifica Silver intercepts gold-silver at Claudia; extends Justina vein to 600 m

Vancouver, British Columbia--(Newsfile Corp. - June 11, 2026) - Pacifica Silver Corp. (CSE: PSIL) (OTCQB: PAGFF) ("Pacifica Silver" or the "Company") is pleased to announce assay results from an additional 28 holes from its ongoing Phase II 20,000-metre diamond drilling program at the 100% owned Claudia Silver-Gold Project ("Project"), located in the historic El Papantón Mining District in Durango State, Mexico. Multiple holes returned strong gold-silver intercepts and follow-up drilling on the recent high-grade Justina vein discovery has successfully extended mineralization along 600 metres of strike length. With the onset of the dry season, the Company has temporarily reduced its active drill fleet from three rigs to two to ensure safe and efficient operations while still maintaining strong drilling momentum across key targets.

The fully funded Phase II program commenced in mid-January 2026 and is now expected to be completed in the third quarter of 2026, with 12,750 metres drilled in 54 holes as of June 10. In addition, the Company has completed a 31.6 line-kilometre induced polarization (IP) and resistivity (RES) survey over the central portion of the property. The survey has identified a significant high-chargeability anomaly that is currently being reviewed by the technical team for follow-up drill targeting.
