VANCOUVER, BC / ACCESS Newswire / June 2, 2026 / Silver X Mining Corp. (TSXV:AGX)(OTCQX:AGXPF)(F:AGX) ("Silver X" or the "Company") is pleased to report new underground diamond drill results from the Blenda Rubia ("BR") target, located within the Company's Nueva Recuperada Unit in central Peru. The latest results from hole DDH-BR-016 continue to confirm that Blenda Rubia is evolving into a broader and more scalable polymetallic mineralized system than would be implied by a simple narrow-vein interpretation.

Importantly, the Company believes these results further support the view that Blenda Rubia has the potential to become an increasingly relevant growth front within Nueva Recuperada. The repetition of broad mineralized intercepts across multiple drill holes indicates that these wider zones are not isolated local features, but rather part of a mineralized system with the potential to support a larger mining footprint, increased operational flexibility and, over time, a more scalable development scenario.

Hole DDH-BR-016 was drilled from Platform No. 003 to a final depth of 305.70 meters and intersected a mineralized structural zone of 104.20 meters apparent width, equivalent to 40.71 meters true width, between 179.30 meters and 283.50 meters. The interval returned average grades of 69.53 g/t Ag, 0.87% Pb, 0.28% Zn and 0.02% Cu, equivalent to 98.7 g/t AgEq. These results confirm continuity of the polymetallic system at depth, approximately 60 meters below the last level historically recognized by Buenaventura, and reinforce the Company's view that Blenda Rubia may support a more ambitious ramp-up scenario as drilling continues to expand the scale and continuity of the mineralized corridor.

The Company interprets these results as further evidence that mineralization at Blenda Rubia is not restricted to discrete veins, but is instead developed within a broader mineralized corridor composed of principal veins, tensional structures, moderate veinlet stockworks, silicified horses and altered host rock. This broader geometry is increasingly important from a corporate perspective, as it may enhance the project's scalability, support wider mineable zones in selected sectors, and strengthen Blenda Rubia's potential role in Silver X's production ramp-up strategy at Nueva Recuperada.

Blenda Rubia Highlights:

• DDH-BR-016 intersected 104.20 meters apparent width, equivalent to 40.71 meters estimated true width, grading 69.53 g/t Ag, 0.87% Pb, 0.28% Zn, 0.02% Cu, equivalent to 98.7 g/t AgEq.

• Vein 1 returned 4.12 meters estimated true width grading 209.78 g/t Ag, 2.10% Pb, 0.61% Zn, 0.01% Cu (274.5 g/t AgEq), representing the highest-value internal interval within the broader mineralized zone.

• Vein 3 returned 2.64 meters estimated true width grading 140.37 g/t Ag, 1.25% Pb, 0.12% Zn, 0.01% Cu (172.1 g/t AgEq).

• An additional tensional structure returned 2.85 meters estimated true width grading 94.42 g/t Ag, 1.25% Pb, 0.33% Zn, 0.01% Cu (132.4 g/t AgEq).

• The intercept lies at an approximate elevation of 4,160 masl, approximately 60 meters below the last level recognized by Buenaventura at Level 210 (4,220 masl), confirming down-dip continuity of the Blenda Rubia polymetallic system.

• The results support the interpretation of Blenda Rubia as a broader polymetallic corridor comprising principal veins, tensional structures, moderate stockwork, silicified horses and altered wall rock, rather than mineralization restricted to discrete veins.

Drill hole DDH-BR-016 recognized a mineralized structural zone from 179.30 meters to 283.50 meters, corresponding to 104.20 meters apparent width and 40.71 meters estimated true width. Across this broad interval, average grades were 69.53 g/t Ag, 0.87% Pb, 0.28% Zn and 0.02% Cu (98.7 g/t AgEq).

These results confirm that mineralization at Blenda Rubia is not restricted to discrete veins, but instead develops within a broader mineralized corridor comprising principal veins, tensional structures, moderate stockwork, silicified horses and altered wall rock. Importantly, when viewed together with previously reported wide intercepts such as DDH-BR-003, DDH-BR-005 and DDH-BR-009, DDH-BR-016 indicates that these broad mineralized packages are not isolated local occurrences. Rather, they appear to be a repetitive feature of the system that may support project scale-up and wider mining fronts in selected sectors as exploration advances.

1. Results were obtained from external laboratory analyses. Estimated true widths are based on the Company's current geological interpretation and ongoing vein modelling and may be adjusted as interpretation is refined.

2. AgEq note: Silver-equivalent grade is calculated on a metal-price basis (recoveries not applied) as AgEq (g/t) = Ag + [(Pb% × 20.94) + (Zn% × 28.66) + (Cu% × 94.80)] ÷ 0.9645, using assumed prices of US$0.96/g Ag, US$0.95/lb Pb, US$1.30/lb Zn and US$4.30/lb Cu (to be confirmed against the official price deck).
