Silver Acadia Exploration Inc. (CSE: SLA) is pleased to announce additional high-grade assay results from the Phase 1 drill program at the Hachey Zone on its flagship Nicholas-Denys Project. The Company is also reporting the results of a comprehensive structural study completed by Terrane Geoscience Inc. from Fredericton, NB, which provides a new geological framework for understanding the controls on silver, gold, and zinc mineralization at the property.

The integration of detailed structural mapping, recent Phase 1 drilling results and recent compilation of more that 125,000m of historical drilling on the property has positively impacted the Company’s knowledge of the mineralizing system and will guide future Phase 2 drill program.

Highlights

• Expansion of Hachey Zone – Additional high-grade silver-gold assay results continue to expand the Hachey Zone.
• Potential 3 km zone containing multiple high grade silver shoots within a lower grade mineralized envelope,
• Compilation of drilling, surface mapping and structural modelling suggests the development of a mineralized corridor extending approximately 3 kilometres, with multiple connected zones grading over 100 g/t Ag. Additional drilling and geological work are required to confirm its continuity and extent.
• Structurally controlled system for better targeting of future drilling – Independent structural study confirms that the principal silver-gold mineralization is structurally controlled.
  • A minimum of two high-grade silver mineralizing events are present as cross-cutting evidence is visible.
  • Mineralization is concentrated along northeast-southwest trending shear zones and S1 foliation, providing predictable controls for future drilling.
  • Geological evidence supports a magmatic-hydrothermal mineralizing event associated with the Late Devonian Nicholas-Denys granodiorite.
• High grade gold potential – A potential third and younger gold-bearing mineralization event may overprint the two earlier silver-rich systems, representing a new exploration opportunity.

Structural Study Defines Controls on Mineralization

“This structural work program has significantly improved our understanding of the controls on high-grade silver mineralization.,” said Julien Davy, CEO of Silver Acadia. “Instead of viewing Hachey as a collection of isolated high-grade intercepts, we now recognize a structurally controlled mineralizing system that can be systematically targeted. This substantially increases our confidence as we continue to expand the discovery through future drilling.”

Silver Acadia commissioned Terrane Geoscience Inc., from Fredericton, New-Brunswick to complete an integrated structural mapping and interpretation of the Hachey and Shaft Zones.

The study concludes that the principal silver-gold-zinc mineralization (“M1” and “M2”) are structurally controlled and occurs preferentially along the regional S1 foliation and within northeast-southwest trending shear zones. These structures are interpreted to have acted as the primary pathways for hydrothermal fluids responsible for mineral deposition.

The orientation of these mineralized structures is broadly parallel to the regional Rocky Brook-Millstream Fault, suggesting this major crustal-scale structure played an important role in focusing mineralizing fluids throughout the district.

Structural relationships indicate that M2 mineralization formed during, or immediately following, the first recognized deformation event (D1). Furthermore, the close spatial relationship between mineralization and the Late Devonian Nicholas-Denys granodiorite (381 ± 4 Ma) supports a magmatic-hydrothermal origin for the mineralizing fluids.

Evidence for a Later Gold Event

The structural study also identifies a younger mineralization phase (“M3”) consisting of carbonate-quartz-pyrite veinlets that clearly crosscut both the earlier alteration and the principal silver-lead-zinc mineralization.

The later hydrothermal event may be associated with enhanced gold grades observed in several recent drill intersections. Additional work is required to confirm this interpretation and presents an important opportunity to better understand and target higher-grade gold mineralization across the Hachey system.

“One of the most exciting outcomes of this study is the recognition that gold may belong to a later mineralizing event rather than simply occurring within the main silver-rich system,” added Mr. Davy. “If confirmed through continued drilling and petrographic work, this opens an entirely new exploration vector and further demonstrates the complexity and potential scale of the Nicholas-Denys mineralizing system.”

Drill Results

The latest drill holes continue to intersect significant silver, gold and zinc mineralization within the Hachey Zone, supporting the Company’s interpretation of a structurally controlled mineralized corridor.

Full details regarding the Phase 1 drill program were previously disclosed in the Company’s April 1, 2026, and April 23, 2026, press releases. The drilling campaign at the Hachey Zone, located on the Nicholas-Denys Property, commenced in January 2026 and is a silver-gold-zinc-lead mineralized system interpreted as an epithermal-style vein environment. Drilling intersected a sequence of strongly foliated sedimentary rocks consisting of alternating wacke and mudrock units, hosting early quartz veins, massive sulphide veins, and rare porphyritic felsic intrusive dykes.

Table 2 Assay results received since the last news release:

1. All assay values are uncut, and intervals reflect drilled intercept lengths. True widths have not been determined as the mineralized body remains open in all directions. Further drilling is required to determine the mineralized body orientation and true widths.
2. Ag Equivalent (AgEq): Only samples with over 5g/t Ag and over 0.05g/t Au were used – All metals are reported in USD and calculations consider recoveries of 90 % for gold, 80 % for copper, and 80 % for silver. The following metal prices were used to calculate the AgEq metal content: $50/oz silver, $4,000/oz gold (ratio Au:Ag = 80:1), $6.00/lb copper (ratio Cu:Ag = 0.008:1), $0.82/lb lead (ratio Pb:Ag = 0.001:1) and $1.59/lb zinc (ratio Zn:Ag = 0.002:1).
