Pacifica Silver Identifies New High-Grade Aguilareña Mineralized Shoot and Provides Exploration Update At Claudia Project
Pacifica Silver announced assay results from an additional 14 holes from its ongoing definition and expansion Phase II 20,000-metre diamond drilling program at the 100% owned Claudia Silver-Gold Project, located in the historic El Papantón Mining District in Durango State, Mexico. The latest results have identified a new high-grade mineralized shoot north of the historical Aguilareña shaft that hosts the highest gold and silver grades over some of the widest intervals drilled on the property to date. Drill Result Highlights (Estimated True Widths): 4.44 m @ 8.00 g/t Au and 65 g/t Ag (754 g/t AgEq) from 65.85 m in Hole 26CLAU115D including 1.99 m @ 17.40 g/t Au and 117 g/t Ag (1,613 g/t AgEq) including 0.63 m @ 37.40 g/t Au and 56 g/t Ag (3,274 g/t AgEq); 2.54 m @ 1.41 g/t Au and 866 g/t Ag (987 g/t AgEq) from 99.65 m in Hole 26CLAU112D including 0.41 m @ 5.63 g/t Au and 5,100 g/t Ag (5,584 g/t AgEq); 3.97 m @ 2.00 g/t Au and 112 g/t Ag (284 g/t AgEq) from 110.15 m in Hole 26CLAU118D including 1.38 m @ 4.72 g/t Au and 271 g/t Ag (677 g/t AgEq) including 0.51 m @ 9.19 g/t Au and 577 g/t Ag (1,367 g/t AgEq). Phase II Drilling Update: The Company’s fully funded Phase II program, which commenced in mid-January 2026, remains on track for completion in the third quarter of 2026. As of July 27, 16,278 m have been drilled in 71 holes. Drilling at the newly identified Judy anomaly continues, with three holes completed to date. The deepest hole reached a vertical depth of 402 m. All three holes intersected encouraging silica- and sulfide-cemented breccias containing visible fine-grained pyrite, galena, sphalerite and chalcopyrite. The style of alteration and mineralization indicates a deeper position in the system relative to previous drilling to the north and west. Follow-up drilling is in progress, and additional updates and assay results will be released as they become available. Following the return of the rainy season and restoration of water availability at the Project, the Company has increased the number of active drill rigs from two to three to accelerate the Phase II drill program. Technical Discussion of Drill Results – Aguilareña Vein: Expansion of High-Grade Aguilareña Vein System: Phase II drilling continues to successfully intercept and extend the main Aguilareña vein system. The latest results have identified an emerging mineralized shoot north of the historical Aguilareña shaft within the overall mineralized footprint of nearly 2 km of strike length and approximately 200 m down-dip. Recent drilling north of the Aguilareña shaft included 14 drill holes that intersected the vein over approximately 325 m of strike length (northings 2,774,300 to 2,774,625). This work filled a critical gap in drill coverage and outlined a new high-grade mineralized shoot centered around northing 2,774,400. Intercepts in this area are particularly wide, with estimated true widths of the main Aguilareña vein reaching up to 5 m, within a wider zone of mineralized hanging-wall and footwall stockwork and breccia measuring up to 14 m (estimated true width). Hole 26CLAU112D (near northing 2,774,300) intersected a thick package of veins and breccias averaging 0.66 g/t Au and 170 g/t Ag (226 g/t AgEq) over 14.54 m (est. true width). Toward the hanging wall, a high-grade silver zone returned 866 g/t Ag and 1.41 g/t Au (987 g/t AgEq) over 2.54 m (est. true width) within an oxidized quartz breccia. Hole 26CLAU115D, located in the core of an emerging mineralized shoot, intersected the Aguilareña vein grading 8.00 g/t Au and 65 g/t Ag (754 g/t AgEq) over 4.44 m (est. true width). This includes a high-grade gold zone of 17.40 g/t Au and 117 g/t Ag (1,613 g/t AgEq) over 1.99 m (est. true width) within an oxidized fault zone (some core recovery loss). Hole 26CLAU118D intersected another wide vein structure returning 2.00 g/t Au and 112 g/t Ag (284 g/t AgEq) over 3.97 m (est. true width), including 4.72 g/t Au and 271 g/t Ag (667 g/t AgEq) over 1.38 m (est. true width) within a quartz breccia with visible pyrite, chalcopyrite, sphalerite and silver sulfides. In addition to the main Aguilareña vein, drilling has identified several narrower, often strongly mineralized structures in the hanging wall and footwall.
