Montreal, Quebec--(Newsfile Corp. - April 1, 2026) - Silver Acadia Exploration Inc. (CSE: SLA) ("SLA" or the "Company") is pleased to announce the successful completion of its Phase 1 diamond drilling program primarily targeting high-grade silver, gold and antimony on its flagship Nicholas-Denys Project and its Sedex project both located within the prolific Bathurst Mining Camp ("BMC") in northern New Brunswick. Results for the Nicholas-Denys (silver/gold) are still pending with today's release reporting high grade Antimony from the Sedex property. The Company is also providing an exploration update, summarizing initial observations from the drill program, and announcing the expansion of its strategic land position.

Julien Davy, President and CEO commented, "While we continue to prioritize the Nicholas-Denys silver-gold project, these initial high-grade near-surface antimony results at Sedex are particularly compelling. Grades of this magnitude over a trend exceeding 150 to 200 metres are uncommon in the Bathurst VMS environment and may point to a distinctive and highly prospective intrusive-related antimony system. The Sedex property is clearly a multi-element environment that has yet to reveal its full potential, encompassing potential gold systems and a VMS environment prospective for high-grade silver, and we are eager to advance follow-up drilling to further define the scale of this emerging discovery."

Antimony is designated as a critical mineral due to its essential role in defense, electronics and emerging clean technology supply chains. Its primary use is as a strengthening agent in lead-acid storage batteries, while additional applications include flame retardants, military technologies and semiconductor manufacturing. Global antimony production is heavily concentrated in a small number of countries, creating supply chain vulnerabilities. As a result, the development of potential antimony sources in stable mining jurisdictions such as Canada is increasingly viewed as strategically important for securing reliable and diversified supply.

Antimony results on the Sedex Property

Located within the core of the Bathurst Mining Camp, the Sedex Property represents a prospective VMS exploration target and also hosts surface gold anomalies that have not yet been systematically evaluated.

The property also hosts an antimony showing originally identified by Noranda during its 1989-1990 exploration programs. This work reported several antimony (Sb) intersections, including grades of up to 13.6% Sb over 0.3 m. No documented follow-up work has been completed since that time.

In late December 2025, Silver Acadia completed four (4) drill holes totaling 216.5 m with the objective of confirming the antimony (Sb) mineralization reported in the historical Noranda drilling.

Silver Acadia's drilling intersected a sequence of volcaniclastic rocks (lapilli tuff) and sedimentary units that are foliated, folded and locally affected by brecciation. The best results, all intersected within approximately 35 m of vertical depth, include:

• 2.2% Sb over 1.1 m incl. 4.2% Sb over 0.6 m
• 0.6% Sb over 3.8 m incl. 2.2% Sb over 0.6 m

Antimony (Sb) mineralization occurs within breccia zones and is generally associated with a system of subparallel quartz veins hosted within a sheared and altered structural corridor traced over approximately 300 m along a north-south trend. Stibnite (Sb₂S₃) occurs as locally massive veins, radiating euhedral crystals, stringers, and as small massive clusters within the altered host rocks.

Management considers these initial results significant as they validate historical antimony mineralization and confirm the presence of a structurally controlled antimony-bearing hydrothermal system that remains open along strike and at depth. These results highlight the exploration potential of the Sedex Property and support the Company's strategy of advancing high-quality critical mineral targets within the Bathurst Mining Camp.

Phase 1 Drilling program - 3,652.2 m

Davy continued, "Initially planned for 3,200 m, we decided to expand the Phase 1 program to 3,652 m as drilling progressed due to encouraging geological observations. The completion of this first phase represents an important transition from data compilation toward systematic target development. With more than 125,000 metres of historical drilling compiled, extensive historical exploration datasets, our 20,000-m core scanning initiative, and this Phase 1 drilling program now completed, we believe we have assembled a strong geological foundation to unlock the potential of our projects and build long-term shareholder value".

On December 9, 2025, Silver Acadia announced the launch of a Phase 1 drilling program targeting three priority areas. Following a short holiday break, drilling resumed in January and was completed on March 6, 2026. The program totaled 3,652.2 m in 27 drill holes.

The objectives of the program were multiple, and the targets were mostly the Nicholas-Denys property (3,438 m) and the Sedex Property (214.2 m).

On the Nicholas-Denys property, the drilling program targeted the Hachey Zone which is an epithermal-type veins enriched in zinc, silver, gold, and lead and historical exploration programs have reported significant intercepts including 204 g/t Ag, 1.3% Zn, 1.0% Pb and 0.86 g/t Au over 16.8m (Hachey, drill hole F07-15), incl. 1,513 g/t Ag, 10.1% Zn, 7.3% Pb and 7.4 g/t Au over 3.4 m ⁽²⁾.

All results are pending for the Nicholas-Denys Property and will start to be released shortly.

Corporate update - Expansion of Strategic Land Position

Following the successful completion of its Phase 1 drilling program and continued confidence in the geological potential of its projects, Silver Acadia has expanded its land position surrounding its priority exploration targets through claim re-acquisitions, additional staking and a new property option agreement.

In connection with the re-acquisition of previously lapsed claims and the staking of additional prospective ground contiguous and adjacent to the Company's existing projects, Silver Acadia has issued an aggregate of 1,300,000 common shares and paid $65,000 in cash to several arm's-length prospectors as consideration for securing the claims.

The prospectors will retain a 2% Net Smelter Return (NSR) royalty, of which 1% may be repurchased by the Company for $1,000,000, subject to customary terms. All securities issued in connection with these transactions are subject to a statutory hold period of four months and one day in accordance with applicable Canadian securities laws.

The transactions are subject to customary conditions, including regulatory approvals where applicable.

These acquisitions are consistent with Silver Acadia's strategy of consolidating a district-scale land position and securing additional exploration upside around its priority targets within the Bathurst Mining Camp.

Drilling sampling method and QA/QC

Diamond drilling was done by Claude Roy Drilling, from Petit-Rocher, New Brunswick. All the NQ-size core is recovered by the drillers, sent to the Petit-Rocher core shack and logged by the geologists. Samples generally vary from 0.3 m to 1.5 m depending on the geological environment. Sample preparation was done internally by technician of the Company, and the drill core was sawed in half, with one half used for chemical analysis and the other half for control purposes.

All samples are sent by the employe of the Company to the ALS Global facility in Moncton, New Brunswick, for preparation. ALS is an accredited laboratory which is independent of the Company. Each sample is dried and crushed to 70% passing -2mm (PREP-31) and 250g are taken to be pulverized to 85% passing 75 microns (200 mesh). Samples are then sent to the ALS Global facility in Vancouver, for assaying. Gold assays were by fire assay fusion with AAS finish on a 50g sample (Au-AA24 method) and the overlimit gold assay was completed by fire assay and gravimetric finish on 50g sample (Au-GRA22 method).

Silver, Antimony, Copper and other elements are then treated for 34 elements by four-acid digestion and analyzed by ICP-AES (ME-ICP61 method).

Quality assurance/quality control (QA/QC) includes the use of duplicates, blank samples and material certified for Au, Ag, Zn, Cu and Sb. QA/QC additions to the sample stream total an additional 10% of samples analysed. No data quality problems were indicated by the QA/QC program.
