PSIL Expands Silver-Gold System with High-Grade Results and New Targets
Pacifica Silver Provides Exploration Update at Claudia Silver-Gold Project; Grants Incentive Stock Options
Vancouver, British Columbia — (Newsfile Corp. — April 2, 2026)
Pacifica Silver Corp. (CSE: PSIL) (OTCQB: PAGFF) (“Pacifica” or the “Company”) is pleased to provide an update on exploration activities at its 100% owned Claudia Silver-Gold Project located in Durango State, Mexico. Recent assay results from 286 surface channel samples collected in late 2025 and early 2026 have enabled the Company to identify and commence drill testing of two new high-priority targets at the Pinolera zone and recently recognized Contraria vein swarm.
These targets are included in the Company’s ongoing 20,000-metre Phase II drill program where a total of 35 holes totaling over 8,854 m have been drilled as of March 30th. The Company has also granted 1.4 million incentive stock options to directors, officers, advisors and consultants.
Building on positive rock-chip sampling results announced on October 9, 2025, recent multi-element assay results from 286 surface channel samples collected between late 2025 and early 2026 have confirmed high-grade silver and gold mineralization at surface in previously unsampled and underexplored areas in the southern portion of the property.
The ongoing channel sampling and mapping program, focused on the area between the historical Tres Reyes and Mina Vieja mines, has:
- Extended known silver-gold mineralization at the Tres Reyes vein by 250 m to the south
- Extended known mineralization at the Pinolera zone to nearly 600 m
- Further refined the Justina vein extent to approximately 750 m
- Filled in multiple transects across the Contraria vein swarm
Highlights from channel sampling include:
- 17.5 g/t Au & 59 g/t Ag over 0.6 m
- 4.82 g/t Au & 66 g/t Ag over 1.5 m
- 1.64 g/t Au & 109 g/t Ag over 1.5 m
- 0.51 g/t Au & 117 g/t Ag over 0.5 m
- 1.48 g/t Au & 63 g/t Ag over 1.5 m
The highest gold assays were obtained from quartz veins in the Contraria vein swarm northwest of Mina Vieja, including 17.5 g/t Au and 59 g/t Ag over 0.6 m and 4.82 g/t Au and 66 g/t Ag over 1.5 m (Figure 1). At surface, the Contraria vein swarm consists of multiple intermittently exposed, subparallel quartz veins, up to approximately 20 cm in width individually, that extend over an area 300 m wide and 1.2 km from the Guadalupana vein to Mina de Oro.
The highest silver assays of 117 g/t Ag and 0.51 g/t Au as well as 109 g/t Ag with 1.64 g/t Au came from the southern Tres Reyes vein and the eastern Pinolera zone, respectively. The Pinolera zone is a N70W-striking, up-to-40-m-wide zone of subparallel veins that intersects the Justina vein and extends west to the Tres Reyes vein.

Note: Multiple samples were taken at various sites along lines perpendicular to veins and vein breccia or sheeted vein zones; at this zoom level, the symbols overlap and are not visible individually.
As of March 30th, the Company has drilled over 8,854 m in 35 diamond-core holes, including 354 m in three Phase I holes that were re-entered and deepened.
The 20,000 m Phase II drill program is designed to:
- Continue extending zones of high-grade silver-gold mineralization at the Aguilareña vein
- Follow up on the recent high-grade discovery at the Justina vein (see news from February 9, 2026)
- Aggressively drill test the southern extension of the Aguilareña-Tres Reyes vein
- Drill test the high-priority Justina vein, Contraria vein swarm, Pinolera, Mina Vieja and Mina de Oro areas
Pacifica’s mapping and sampling program is ongoing to cover widespread areas of the Claudia project that have been previously underexplored. For the 286 samples analyzed as of March 14th, a statistical breakdown of assays based on silver and gold grades is as follows:
- Top 11 samples (4%) assayed ≥30 g/t Ag — max 117 g/t Ag, avg 61 g/t Ag & 2.68 g/t Au
- Top 23 samples (8%) assayed ≥18 g/t Ag — avg 40 g/t Ag & 1.43 g/t Au
- Across all 286 samples, avg was 5 g/t Ag & 0.19 g/t Au, including 213 samples at or below the 2 g/t Ag detection limit
- Top 8 samples (2.8%) assayed ≥1.00 g/t Au — max 17.5 g/t Au, avg 3.78 g/t Au & 43 g/t Ag
- Top 18 samples (6%) assayed ≥0.5 g/t Au — avg 2.06 g/t Au & 33 g/t Ag
- Top 46 samples (16%) assayed ≥0.2 g/t Au — avg 1.00 g/t Au & 21 g/t Ag
- Top 73 samples (26%) assayed ≥0.1 g/t Au — avg 0.68 g/t Au & 15 g/t Ag
- For 233 samples at or above detection limit: avg 0.23 g/t Au & 6 g/t Ag; 53 samples (18%) below 0.005 g/t Au detection limit
The surface sample results in this news release are from channel samples collected by Pacifica geologists and field technicians with sample locations recorded using hand-held GPS receivers with an estimated precision of ±3.0 m. Channel samples were taken by cutting two parallel slots about 2–3 cm in depth and continuously over horizontal lengths of 0.45 to 3.5 m (average 1.4 m) using portable masonry saws. The rock between the slots was extracted by hammer and chisel; individual samples averaged 2.4 kg in weight. Samples were placed in numbered plastic sample bags closed with ties. Coarse preparation blanks of similar weights were inserted into the sample stream for QA/QC purposes. The individual samples and inserted QA/QC blanks were placed in numbered shipping sacks and stored in Pacifica’s gated and locked warehouse in Santiago Papasquiaro, Durango.
The samples were transported to SGS de Mexico (SGS) in Durango City, Durango, Mexico by Pacifica personnel and contract field technicians. SGS is an independent commercial analytical laboratory accredited under ISO/IEC 17025. At SGS, samples were weighed, dried at 55°C and crushed in their entirety to -10 mesh. The crushed material was split to obtain approximately 200-gram subsamples pulverized to 85% at -200 mesh. Gold was analyzed by fire-assay fusion of 30-gram aliquots with an atomic absorption spectrometry (AAS) finish. Samples assaying greater than 10 g/t gold were re-assayed by 30-gram fire-assay fusion with a gravimetric finish. Silver and 33 major, minor and trace elements were determined by inductively-coupled plasma-emission spectrometry (ICP-AES) following aqua-regia digest of 0.2-gram aliquots. Samples assaying greater than 100 g/t silver were re-assayed by 30-gram fire-assay fusion with an AAS finish.

Pacifica Silver Corp. 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% owned Claudia Silver-Gold Project located in Durango, Mexico. Spanning 11,876 hectares, the Project encompasses most of the historic El Papantón 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% of over 30 km 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.
