Pacifica Silver Corp. (OTCQB:PAGFF) is set to initiate a comprehensive exploration program at its wholly-owned Claudia Silver-Gold Project in Durango, Mexico, beginning in Fall 2025. The planned activities include an 8,000-meter Phase I drilling campaign, slated to commence in late September 2025, coupled with extensive property-wide exploration efforts.
The Claudia Project boasts an 11 km-long horsetail structural complex known for its high-grade silver and gold deposits. Previous drilling in 2021 generated significant intercepts, including 9.15 meters averaging 688 g/t silver equivalent and 4.15 meters at 554 g/t silver equivalent. The upcoming program aims to expand upon these known high-grade zones and to assess previously undrilled targets.
In addition to drilling, the exploration plan includes surface sampling and geological mapping. Crucially, the Company will conduct a 27-line km Induced Polarization (IP) and resistivity geophysical survey in Q4 2025, a first for the property. To date, only about 10% of the project’s 30+ kilometers of known veins have been tested by drilling, promising significant potential for new discoveries.

Vancouver, British Columbia – Pacifica Silver Corp. (CSE: PSIL) (OTCQB: PAGFF) (“Pacifica” or the “Company”) announced details of its upcoming Fall 2025 exploration program at the Company’s Claudia Silver-Gold Project (“Project”) in Durango, Mexico. The program will feature an 8,000-meter Phase I drill campaign, slated to begin at the end of September, alongside property-wide exploration encompassing surface sampling, geological mapping, and a 27-line km Induced Polarization (IP) and resistivity geophysical survey.
“Pacifica Silver is poised to embark on one of the most significant exploration efforts in the Claudia Project’s history,” stated Todd Anthony, Chief Executive Officer of Pacifica. “Drilling in 2007 and 2021 by previous operators confirmed high-grade silver-gold mineralization near historical mine workings over approximately 2 km of strike along the Aguilareña vein, part of the adjacent Guadalupana vein, and the Veta Central vein. Our upcoming Phase I drill program aims to expand upon these zones of known high-grade mineralization and test previously undrilled, high-priority targets. Concurrently, our team will conduct boots-on-the-ground geological work to enhance our understanding of the Project’s geologic model and identify new targets for future drill programs.”
Overview
The Claudia Project, situated in the historical El Papantón mining district of Durango, Mexico, features high-grade silver and gold mineralization within quartz-adularia veins and breccias. These are hosted along multiple northwest-striking structures that form an extensive 11 km-long horsetail structural complex. Among these structures are four principal veins and numerous vein offshoots, with much of past exploration concentrated on portions of the Aguilareña and Guadalupana veins, where a previous operator defined a historical resource in the early 1990s.
Approximately 10% of more than 30 kilometers in strike length of known veins have been tested by drilling. Surface mapping and trenching, coupled with multiple small-scale historical mine workings, suggest strong potential for additional high-grade silver-gold discoveries. These are anticipated along the Aguilareña-Tres Reyes, Guadalupana and Veta Central veins, and across at least 10 other untested structures in the vein array. Large areas of the vein array have yet to be mapped and sampled, highlighting further untapped potential.
Phase I Drill Program
The Company plans to initiate an 8,000-meter Phase I drill program in late September 2025. The program aims to expand known high-grade silver-gold zones by:
(1) Stepping out from higher-grade intercepts encountered in 2021 drilling by a prior operator (Durango Gold) along portions of the Aguilareña, Guadalupana, and Veta Central veins; and
(2) Drill testing high-priority, previously undrilled targets at the Mark Twain, Veta West and VCE veins.

The initial phase of drilling is planned to extend from the most promising intercepts identified during the 2021 drilling campaign conducted by Durango Gold. Key intercepts include Hole 21CLAU011D, which intersected 9.15 metres at an average of 688 g/t silver equivalent (AgEq calculated using an 80:1 silver-to-gold ratio), from 157.75 metres, including 3.15 metres of 1,352 g/t AgEq. Additionally, Hole 21CLAU34D intersected 4.15 metres of 554 g/t AgEq from 140.8 metres, including 0.55 metres of 1,955 g/t AgEq (see Table 1). Priority holes are also planned to potentially expand the fully open Veta Central mineralization discovered in 2021 with hole 21CLAU31D that returned 6.05 metres of 192 g/t AgEq from 62.1 metres, including 1.0 metre of 437 g/t AgEq.
Furthermore, the Company intends to drill test high-priority, previously untested targets, such as the silver-rich Mark Twain vein, identified from historical underground sampling conducted in the early 1990s. Two additional targets, Veta West and the VCE structural intersection, have been prioritized due to strongly anomalous silver-gold values observed in past surface rock chip sampling. The Veta West drilling will focus near the intersection of the Aguilareña and Mark Twain veins, while the primary target at VCE is the intersection between a north-south and east-west striking vein, structurally favorable locations for silver-gold mineralization.
The Company has engaged a skilled drilling contractor based in Durango to execute the drill program.

Property-wide Exploration
Concurrently with the Phase I drill program, Pacifica’s geological team and field personnel will undertake detailed geological mapping and systematic surface sampling. This initiative aims to enhance the Company’s understanding of the Project’s mineralized system, of which only a fraction has been mapped and sampled by previous operators. Many of the Project’s earlier-stage targets, such as La Concepcion, Providencia, Mina de Oro/Mina Vieja, include historical mine workings that have yet to be comprehensively mapped and sampled.
This broad exploration effort aims to identify and delineate additional vein outcrops, particularly within the northwest-striking horsetail structural complex, and to refine the structural and lithological controls on high-grade silver-gold mineralization. The Company believes there is strong potential to define new high-priority drill targets for upcoming drill programs.
Moreover, the Company plans to conduct a 27-line-kilometer IP and resistivity survey during the fourth quarter of 2025. This marks the first geophysical surveys conducted at the Project, aiming to identify chargeability features associated with mineralized veins and potentially locate prospective veins that have not yet been sampled or drilled.
