PACIFICA SILVER'S FIRST IP SURVEY IDENTIFIES LARGE, NEAR-SURFACE CHARGEABILITY ANOMALY AT CLAUDIA; DRILL TESTING COMMENCES ON NEW "JUDY" ANOMALY

Pacifica Silver Corp. has completed a 31.65-kilometre induced polarization (IP) and resistivity (RES) geophysical survey at the 100-per-cent-owned Claudia silver-gold project in Durango state, Mexico. Representing the first geophysical survey conducted at Claudia, the program was designed to investigate the nature of the project's extensive vein systems and has successfully identified a large, near-surface, volcanic-rock-hosted chargeability anomaly in the southern portion of the property. Due to the strength of the new Judy anomaly, the company has relocated one drill rig from its continuing phase II program to commence drilling an initial five holes on the anomaly.

Highlights

• Survey completed: Approximately 31.65 line kilometres of IP-RES surveying was competed across 10 lines (numbered 2 through 11) in the southern portion of the Claudia project, aimed at enhancing the company's understanding of the project's extensive vein systems.
• Major chargeability anomaly identified: A significant zone of highly elevated chargeability was delineated on lines 8 and 11, extending 600 metres in a northeast-southwest direction. The anomaly displays a probable north-south trend, remains recognizable for an additional 680 metres to the northwest of the strongest response, and decreases in intensity while plunging northward.
• Highest and strongest response near surface: The strongest portion of the anomaly, with chargeability values of 24 to 30 milliradians (mrad), is modelled at shallow depths of approximately 75 to 150 metres below surface on Line 11 and coincides with a zone of high resistivity.
• Geometry and interpretation: The anomaly dips gently to the east and north, broadening to the northwest at lower chargeability values (16 t 22 mrad). It is best interpreted as a bulk-volume response consistent of disseminated or stockwork sulphide mineralization within a non-graphitic volcanic host-rock sequence.
• Drilling Judy: Due to the strength of the Judy anomaly, the company relocated one of two operating drill rigs from its continuing phase II program to begin drill testing the target in late June. The company plans to drill an initial five holes into the Judy anomaly over the coming weeks.

"We are very encouraged by the results of our first-ever geophysical survey at Claudia," stated Todd Anthony, chief executive officer of Pacifica Silver. "The survey has identified a large, near-surface chargeability anomaly that ranks among the strongest targets on the property. The discovery of this new target in an underexplored area, combined with our ongoing phase II drilling success, strongly reinforces our confidence in the district-scale potential of the Claudia project. By mobilizing a drill rig immediately to the area, we are eager to test this anomaly without delay and to receiving results in the coming weeks."

Technical survey discussion

The IP-RES survey was completed across 10 northeast-southwest oriented lines spaced 140 to 700 metres apart, targeting key structural corridors including the Aguilarena-Tres Reyes, Guadalupana and Central veins, as well as previously underexplored areas to the east of these veins with limited historical sampling and no prior drilling. The survey used dipole-dipole and pole-dipole arrays with 50- and 100-metre electrode spacing, achieving investigation depths of up to 200 metres below surface. A total of 31.65 line kilometres of data were collected along lines oriented perpendicular to the principal vein trends. The program was designed and supervised by Pacifica Silver's technical team in collaboration with Zonge International, a leading geophysical contractor.

Phase II drilling update

As of July 4, 2026, a total of 14,539 metres has been drilled in 64 holes in the company's continuing, fully financed 20,000-metre phase II drill program. Additional updates on drilling progress and assay results will be provided as they become available.

About Pacifica Silver Corp.

Pacifica Silver is a Canadian resource company led by a proven management team with decades of mining and exploration experience in Mexico. The company is focused on its 100-per-cent-owned Claudia silver-gold project located in Durango, Mexico. Spanning 11,876 hectares, the project encompasses most of the historic El Papanton mining district where at least nine small mines operated intermittently during the 20th century. Since 1990, sampling and drilling within have returned high-grade silver and gold intercepts across multiple vein systems, with only 10 per cent of over 30 kilometres of known veins having been drilled. Today, the project is a prime target for modern exploration and holds exceptional potential for new high-grade discoveries.
