Pacifica Silver Reports Initial Phase Ii Drill Results At Claudia with Multiple High-Grade Intercepts At the Aguilareña Area. The Company is currently working to determine the number of individual veins, their lateral and vertical extents and potential connections between intersections. Further Phase II drilling is planned to explore this emerging high-grade hanging-wall mineralization at the Aguilareña vein.
Central Vein Results: Holes 26CLAU079D and 26CLAU082D were drilled to test the up-dip and northern extensions of the mineralized zone found in historical hole 21CLAU031D. Hole 26CLAU079D was collared 135 m south of the historical hole, while hole 26CLAU082D was collared approximately 80 m north. Both holes were also positioned to test up-dip from holes 25CLAU042D and 25CLAU055D, with hole 26CLAU082D also located 50 m down-dip from 21CLAU031D.
Results are shown in Table 1 and selected results are discussed below. Hole 26CLAU079D intersected the Central vein over 2.7 m averaging 1.71 g/t Au and 124 g/t Ag, from 78.7 m. The vein contained 0.60 m averaging 4.44 g/t Au and 324 g/t Ag (706 g/t AgEq), half of which assayed 6.37 g/t Au and 533 g/t Ag. The intercept in hole 26CLAAU079D on the Central vein returned higher gold and silver grades than those encountered in all historical drilling and the Phase I program, although the mineralized width was narrower than the 6.05 m interval grading 1.27 g/t Au and 90 g/t Ag reported in hole 21CLAU031D (from 62.1 m).
These higher-grade results confirm the Central vein as a compelling target warranting additional drilling at both shallower and deeper levels. The 2026 drill samples reported here were collected from HQ-diameter core and were logged and sampled at the Pacifica Silver gated and enclosed facility in Santiago Papasquiaro, Durango. Sample lengths varied from 0.30 to 1.85 m, with the majority being = 0.85 m in length.
Pacifica Silver geologists marked the core lengthwise to best divide the core into halves, perpendicular to veins, mineralized fractures and vein-breccia. Sample intervals were cut in half lengthwise and one-half of each sample was placed into pre-numbered plastic sample bags with numbered sample tickets and closed with ties. The closed sample bags were placed into numbered shipping sacks along with numbered bags of coarse preparation blanks and certified reference material (CRMs or ?standards?) inserted with each hole for quality control/quality assurance purposes.
Samples were transported by commercial package delivery to the ALS laboratory in Hermosillo, Sonora, Mexico. At the ALS laboratory, the samples were crushed in their entirety to 70% passing 2 mm, and riffle split to 1-kg subsamples which were pulverized to 85% at 75 µm. ALS then shipped 200 g splits of the pulverized material by air freight to the ALS assay laboratory in North Vancouver, Canada, for analysis. Gold was analyzed by 30 g fire-assay fusion with an Atomic Adsorption (AA) finish (method code Au AA23); samples with >10 g/t Au were re-assayed by fire-assay fusion and gravimetric finish.
Silver plus 34 major, minor and trace elements were analyzed by ICP AES following 4-acid digestion of 0.5 g aliquots (method code MEICP-61). Samples that assayed greater than 100 g/t Ag were re-analyzed by ICP AES following a 4-acid digestion (method code Ag OG62). ALS holds accreditation under ISO/IEC 17025:2017 for specific analytical procedures and is independent of Pacifica Silver.

Table 1 ? Significant Assay Results from Phase II Drill Program at Claudia Project: Composites calculated with Au minimum of 0.15 g/t (0.100 g/t Au if Ag > 30 g/t) and no more than 1.0 m internal below minimum.
*True widths are estimated to average 75% of the reported drilled intervals (the majority range from 76% to 96%). **Silver equivalent grade (AgEq) is calculated based on the following formula: AgEq (g/t) = Ag (g/t) + [Au (g/t) x (Au price /Ag price) x (Au recovery /Ag recovery)]. Metal prices for silver and gold are assumed to be USD 30/oz and USD 2,500/oz, respectively.
At this stage, insufficient metallurgical test work has been completed to determine recoveries for silver and gold at the Claudia property. Accordingly, recoveries of 93% for silver and 96% for gold were applied, based on the 5-year historical average production data reported from First Majestic Silver Corp.'s San Dimas mine. These values are considered reasonable proxies for anticipated recoveries at Claudia due to similarities in deposit style and the relative proximity of the two properties.
