Pacifica Silver Corp. Reports Assay Results from Additional 28 Holes from its Ongoing Phase II 20,000-Metre Diamond Drilling Program at 100% Owned Claudia Silver-Gold Project
Pacifica Silver Corp. announced assay results from an additional 28 holes from its ongoing Phase II 20,000-metre diamond drilling program at the 100% owned Claudia Silver-Gold Project ("Project"), located in the historic El Papantón Mining District in Durango State, Mexico. Multiple holes returned strong gold-silver intercepts and follow-up drilling on the recent high-grade Justina vein discovery has successfully extended mineralization along 600 metres of strike length. With the onset of the dry season, the Company has temporarily reduced its active drill fleet from three rigs to two to ensure safe and efficient operations while still maintaining strong drilling momentum across key targets. The fully funded Phase II program commenced in mid-January 2026 and is now expected to be completed in the third quarter of 2026, with 12,750 metres drilled in 54 holes as of June 10. In addition, the Company has completed a 31.6 line-kilometre induced polarization (IP) and resistivity (RES) survey over the central portion of the property. The survey has identified a significant high- chargeability anomaly that is currently being reviewed by the technical team for follow-up drill targeting. Aguilareña Area Results: Phase II drilling continues to successfully intercept and extend the Aguilareña-Tres Reyes vein system, with mineralization extended 50-100 m down-dip from previous drilling over a 1.0 km strike length. This work provides important lateral infill and down-dip expansion beneath portions of the historical Aguilareña and Tres Reyes underground workings, confirming strong vein continuity both at depth and along strike within the broader 1.9 km of strike length established by Phase I and 2021 drilling. To the south of the Aguilareña shaft, 10 drill holes intersected the Aguilareña-Tres Reyes vein approx. 50-100 m down-dip and laterally from previous drilling, extending silver-gold mineralization by more than 100 m below the historical workings. Hole 26CLAU095D, located approx. 50 m down-dip and midway in the 225 m gap between previous drill holes, intersected a total of 9.15 m of mineralized hanging-wall vein breccia and sheeted veinlets adjacent to and including the Aguilareña-Tres Reyes vein. The main vein returned 2.85 m of 2.30 g/t Au and 207 g/t Ag (405 g/t AgEq) from 167.75 m. Hole 26CLAU105D intersected the Aguilareña-Tres Reyes vein approx. 80 m north of 26CLAU095D. The vein was 4.0 m wide and included 0.40 m grading 2.35 g/t Au and 285 g/t Ag (487 g/t AgEq) from 178.20 m. The nearby hanging-wall zone of sheeted narrow veins was mineralized over 21 m, with a best interval of 0.55 m of 2.13 g/t Au and 69 g/t Ag (253 g/t AgEq) from 147.8 m. Hole 26CLAU107D intersected the Aguilareña-Tres Reyes vein approx. 70 m north of 26CLAU105D and approx. 60 m below the intercept in 26CLAU096D. The mineralized structure was 8.9 m wide and consisted of internal stockwork and sheeted narrow veins bordered by hanging-wall and footwall vein-cemented breccias that averaged 0.94 g/t Au and 101 g/t Ag (182 g/t AgEq) from 170.05 m. This included a high-grade footwall vein-breccia interval of 0.65 m with 6.98 g/t au and 981 g/t Ag (1,581 g/t AgEq) from 178.3 m. To the north of the Aguilareña shaft, three holes targeted the Aguilareña vein both down-dip and laterally from historical and Phase I drilling. All three holes intersected the vein 25-75 m below the northern end of the lowest historical workings. Hole 26CLAU109D intersected six narrow hanging-wall vein intervals starting at 18.6 m down hole, returning gold grades from 1.21 g/t to 6.81 g/t. Four of these intervals also returned silver assays greater than 100 g/t (maximum 277 g/t Ag) over individual widths of 0.40-0.55 m. This strongly mineralized hanging-wall zone extended to within 43 m of the Aguilareña vein, which was intersected at 147.0 m downhole with a width of 6.3 m. The vein contained 0.5 m grading 3.12 g/t Au and 152 g/t Ag (420 g/t AgEq) from 147.0 m. Holes 26CLAU103D and 26CLAU108D confirmed vein continuity in this previously untested area between historical drill intercepts. Both holes encountered weaker gold-silver mineralization 25- 50 m up-dip (respectively) of the stronger intercepts in 26CLAU109D. In summary, Phase II drilling has delivered robust results on both sides of the Aguilareña shaft, demonstrating improving mineralized widths, strong gold-silver grades, and excellent continuity with depth. In the south, wide and high-grade intercepts have extended the Aguilareña-Tres Reyes vein more than 100 metres below historical workings, while drilling to the north has confirmed a well-mineralized hanging-wall vein system and strong main vein intercepts 25-75 m below the lowest historical levels. The Aguilareña system remains open both down-dip and along strike, highlighting potential for significant expansion of known mineralization in this priority target area. Justina Vein Results: Six widely spaced drill holes tested the Justina vein north and south of discovery hole 25CLAU059D. The holes successfully intersected and extended the vein over a total of 600 m strike length, from 26CLAU094D in the north to 26CLAU104D in the south. Hole 26CLAU101D returned 0.45 m of 5.2 g/t Au and 470 g/t Ag (917 g/t AgEq) from 145.65 m, approx. 60 m up-dip of the previously announced discovery hole 25CLAU059D which intersected 2.10 m averaging 3.53 g/t Au and 460 g/t Ag (764 g/t AgEq) from 219.00 m. The Justina vein was extended 250 m north of 26CLAU101D, where Hole 26CLAU094D intersected 2.75 m averaging 2.25 g/t Au and 12 g/t Ag (206 g/t AgEq) from 87.95 m, including 1.00 m at 4.72 g/t Au and 16 g/t Ag (422 g/t AgEq). To the south, Hole 26CLAU110D intersected 0.50 m of 3.35 g/t Au and 600 g/t Ag (888 g/t AgEq) from 104.0 m. Hole 26CLAU104D, the southernmost hole drilled on the Justina vein to date, returned a strong vein apparent width of 2.7 m averaging 0.65 g/t Au and 22 g/t Ag (78 g/t AgEq) from 201.10 m. These results confirm the Justina vein as a significant new discovery, with high-grade silver-gold mineralization now intersected over a 600-metre strike length, representing 75% of the 800-metre intermittently exposed surface trace, and to depths of up to 160 metres below surface. The vein remains open along strike and at depth, positioning Justina as one of the highest-priority targets on the Claudia project with excellent potential for continued expansion. Central Vein Results: Three drill holes tested the down-dip extension of the Central vein over a 400 m strike length. All three holes intersected the Central vein with widths ranging from 0.35 m to 1.85 m. Hole 26CLAU083D intersected the Central vein with 0.35 m @ 1.50 g/t Au and 46 g/t Ag (175 g/t AgEq) from 91.4 m. In addition, a previously unrecognized hanging-wall vein (not exposed at surface) returned 0.40 m @ 2.31 g/t Au and 34 g/t Ag (233 g/t AgEq) from 54.10 m.
