Additional Drill Results At Claudia With Multiple High-Grade Silver-Gold Intercepts

VANCOUVER – Pacifica Silver Corp. reported on the remaining nine holes of its Phase I diamond drilling program at Claudia Silver-Gold Project located in the historic El Papantón Mining District in Durango State, Mexico. The Phase I program, comprising 30 holes for approximately 8,000 metres, was successfully completed in late December 2025. The remaining nine holes were drilled at the principal Aguilareña and Guadalupana vein areas.
”Remaining results from our Phase I Drill Program have rounded out a successful maiden drill campaign that has extended the Aguilareña vein significantly down dip and confirmed the subsurface lateral continuity of the vein along 1.8 km of strike length,” stated Todd Anthony, Chief Executive Officer. “We are very excited by what we have seen during our inaugural program: these narrow, high-grade silver-gold intercepts are a hallmark of classic low-sulfidation epithermal systems and closely resemble the vein style of the nearby San Dimas Mine, which has successfully operated for hundreds of years on similar narrow, high-grade structures. We view these results as highly encouraging, fully aligned with the geological model we are systematically pursuing, and clearly indicative of the discovery potential of this large-scale, underexplored Project.”
Holes 25CLAU053D, 25CLAU054D, 25CLAU057D, 25CLAU065D and 25CLAU066D were drilled north of the Aguilareña shaft. Hole 25CLAU065D, which returned the highest-grade gold intercepts, was drilled as a 120-m step-out to the north at the same elevation as drill hole 25CLAU039D (previously reported). The hole specifically targeted the ~150-m gap between historical holes 21CLAU012D and 21CLAU025D. The hole discovered two narrow, previously unrecognized veins that do not crop out at surface.
These results demonstrate continued expansion potential along the Aguilareña vein system, with hole 25CLAU065D highlighting significant high-grade gold mineralization in both the main vein/hanging-wall zone and newly identified blind structures in a previously unexplored gap. Combined with successful down-dip and lateral extensions in multiple holes, results demonstrate substantial upside for resource growth north of the historical Aguilareña workings and reinforce why the Company’s ongoing Phase II step-out drill program continues to prioritize this prolific vein corridor.
Holes 25CLAU050D, 25CLAU051D, 25CLAU052D and 25CLAU062D were drilled to test the Guadalupana vein approximately 100 to 180 m below historical drill holes.
Holes 25CLAU050D and 25CLAU051D successfully confirmed the vein’s presence and continuity at deeper levels, intersecting drilled widths of 5.1 m and 8.6 m, respectively. While silver-gold grades were modest, the intercepts exhibited classic epithermal textures-including milled fragments of earlier banded quartz cemented by later finely banded quartz-indicating repeated hydrothermal brecciation and boiling events. These features are highly encouraging indicators of silver-gold deposition potential at greater depths within the structure.
Holes 25CLAU052D and 25CLAU062D also intersected the Guadalupana vein, albeit over narrower drilled widths and with lower-grade mineralization.
Collectively, these intercepts provide valuable new geological information regarding the subsurface geometry, structural continuity and hydrothermal characteristics of the Guadalupana vein system. The observed epithermal textures and evidence of repeated brecciation and boiling processes are positive indicators of the vein’s potential to host higher-grade silver-gold mineralization at depth. They reinforce the Guadalupana vein’s strong exploration upside and guide optimized targeting for future step-out and deeper drilling in the ongoing Phase II program, as the Company advances this promising corridor alongside high-grade successes at Aguilareña and recent discoveries elsewhere on the project.
To date, the Company has completed more than 3,650 metres of diamond drilling across 13 core holes using three drill rigs as part of its ongoing Phase II program.
