Pacifica Silver Identifies New High-Grade Aguilarena Mineralized Shoot at Claudia Project; Provides Exploration Update
Rhea-AI Summary
Pacifica Silver (OTCQB: PAGFF) reported new Phase II drill results from its 100%-owned Claudia Silver-Gold Project in Durango, Mexico, highlighted by discovery of a new high-grade mineralized shoot north of the historical Aguilareña shaft. Key intercepts include 4.44 m (est. true width) grading 8.00 g/t Au and 65 g/t Ag (754 g/t AgEq) in hole 26CLAU115D, 2.54 m at 1.41 g/t Au and 866 g/t Ag (987 g/t AgEq) in 26CLAU112D, and 3.97 m at 2.00 g/t Au and 112 g/t Ag (284 g/t AgEq) in 26CLAU118D.
According to Pacifica Silver, the emerging shoot is part of the Aguilareña vein system, now drilled over nearly 2 km of strike and ~200 m down-dip, with mineralization open along strike and at depth. The fully funded 20,000 m Phase II program, started mid-January 2026, has completed 16,278 m in 71 holes, with three rigs active and additional drilling underway at the Judy anomaly.

"These results are extremely encouraging and mark an important step forward at the Claudia Project," stated Todd Anthony, President and CEO of Pacifica Silver. "We have delineated a new high-grade mineralized shoot in the northern portion of the Aguilareña vein that contains the highest gold and silver grades ever drilled on the property, over significantly wider intervals than previously encountered --clearly demonstrating both the high-grade character and district-scale potential of the Aguilareña vein system. With mineralization open along strike and at depth, and with multiple drills currently turning, we have a clear opportunity to rapidly establish a meaningful inventory of high-grade ounces at relatively shallow depths."
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 (see news from July 6, 2026) 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 (Figure 1 and Figure 2, 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). Results are summarized in Table 1 and illustrated in Figures 1 and 2. Select holes are discussed below.

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.
Additional Structures & Exploration Potential
In addition to the main Aguilareña vein, drilling has identified several narrower, often strongly mineralized structures in the hanging wall and footwall. These may represent bifurcations, parallel structures or new veins that may potentially intersect the Aguilareña vein. An oriented-core drilling program is planned for the second half of 2026 to refine the structural interpretation of these mineralized structures and better define the locations of potential new favourable intersections.
Drilling to date has tested only about half of the mapped strike length of the Aguilareña vein system, leaving significant exploration potential along strike. Mineralization in the drilled area also remains open at depth in two zones. Vein textures and metal content indicate that the mineralization identified to date sits relatively high in the epithermal system; follow-up drilling will therefore target potential feeder zones at depth while continuing to test the vein system along strike. Several encouraging surface-mapped structures outside the main Aguilareña vein also remain untested, and detailed surface mapping and sampling are underway to prioritize these targets. A recent structural geology study has further refined drill targeting and improved understanding of the controls on mineralization.
In summary, Phase II drilling north of the Aguilareña shaft has delivered robust results, filling key data gaps while confirming strong mineralized widths, high gold-silver grades and excellent continuity with depth. The Aguilareña system remains open both down-dip and along strike, highlighting substantial potential for significant resource expansion in this priority target area.
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 1.8 m, with an average length of 0.78 m. 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
