"These initial Phase II results highlight strong consistency at the Claudia project, with 14 of 16 holes intersecting silver-gold mineralization, several of which exceeded 1,000 g/t AgEq," stated Todd Anthony, Chief Executive Officer of Pacifica Silver. "These results successfully extend the Aguilareña vein down-dip by up to 150 metres and confirm robust subsurface vein continuity along 1.9 kilometres of strike length. The first hole drilled at the Central vein this year also delivered high-grade mineralization that exceeds prior results in the area. Together, these results reinforce our confidence in the scale, continuity and significant overall potential of this high-grade silver-gold system. We look forward to reporting further results as the Phase II program advances."

Aguilareña Area Results
Phase II drilling to date has successfully intercepted the Aguilareña vein 50 m to 150 m down-dip from previous drilling over a 1.6 km strike length within the 1.9 km of strike length known from Phase I and 2021 drilling. This includes important lateral infill drilling along portions of the Aguilareña vein to the north and south of historical underground workings, further confirming vein continuity below and lateral to Phase I intercepts.
To the north of the Aguilareña shaft, drill holes 26CLAU067D, 26CLAU068D, 26CLAU069D, 26CLAU070D, 26CLAU071D, 26CLAU074D, 26CLAU076D, 26CLAU078D and 26CLAU080D (Figure 1) targeted the Aguilareña and hanging wall veins down-dip and laterally from historical and Phase I drilling. Eight of these nine holes intersected the Aguilareña vein, extending the vein as much as 50 to 150 m down dip from previous drilling, with selected results discussed below and shown in Table 1.
-
Hole 26CLAU068D returned the highest-grade assays of 13.9 g/t Au and 62 g/t Ag (1,258 g/t AgEq over 0.35 m from 157.25 m in a hanging wall vein approximately 120 m south of the 0.30 m interval of 12.3 g/t Au and 206 g/t Ag from 96.20 m in Phase I hole 25CLAU065D.
-
Hole 26CLAU076D intersected the Aguilareña vein approximately 50 m from hole 21CLAU003D, returning 3.05 m of 3.91 g/t Au and 79 g/t Ag (1,100 g/t AgEq) from 144.25 m in the Aguilareña vein, including 0.80 m of 10.3 g/t Au and 214 g/t Ag.
-
High-grade hanging wall veins were also intersected in hole 26CLAU078D with 0.6 m of 11.75 g/t Au and 52 g/t Ag from 128.6 m, and in hole 26CLAU074D with 0.50 m of 9.28 g/t Au and 42 g/t Ag from 139.05, and from 144.20 to 147.80 (3.60 m) averaging 2.54 g/t Au and 49 g/t Ag, including 0.65 m at 8.27 g/t Au and 96 g/t Ag.
To the south of the Aguilareña shaft, holes 26CLAU072D, 26CLAU073D, 26CLAU075D and 26CLAU081D intersected the Aguilareña vein approximately 50 m down dip and laterally from previous drill intersections. A fifth hole (26CLAU077D) tested the intersection of the Aguilareña and Mark Twain veins at shallow depth in a gap with no previous drilling. Results are shown in Table 1 and selected results are discussed below.
-
Hole 26CLAU075D, located slightly down dip and approximately 65 m south of historical hole 21CLAU030D and approximately 50 m down dip from historical hole 21CLAU004D, intersected hanging wall vein breccia with 4.5 g/t Au and 49 g/t Ag from 130.45 to 130.75 m and 6.31 g/t Au and 247 g/t Ag from 155.30 to 156.25 m.
-
Hole 26CLAU077D returned 9.06 g/t Au and 152 g/t Ag over 0.45 m from 27.45 m after passing through the void space of an old working on the Aguilareña vein into 12.55 m of brecciated, mineralized wall rock and subsidiary vein material marking the intersection of the Mark Twain and Aguilareña veins. Mineralization averaged 1.12 g/t Au and 178 g/t Ag (275 g/t AgEq) from 27.45 to 40.0 m. This intersection zone also included 1.50 m of 1.31 g/t Au and 783 g/t Ag from 35.1 m. The West vein was intersected from 113.8 to 114.1 m and assayed 2.11 g/t Au and 159 g/t Ag (341 g/t AgEq).
Seven of the holes reported today intersected narrow, high-grade veins in the hanging wall of the Aguilareña structure, bringing the total number of such hanging-wall intersections in the Phase I and Phase II drill programs to 10. In addition, seven similar high-grade hanging-wall intercepts were recorded in 2021 drilling by the previous operator, Durango Gold, with gold grades ranging from 4.6 to 24 g/t Au, silver grades ranging from 7 to 233 g/t, and silver-equivalent grades ranging from 403 to 2,100 g/t AgEq.
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 (Figure 1). 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.
Quality Assurance/Quality Control
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.

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 US $30/oz and US $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.
About Pacifica Silver Corp.
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 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.
