SILVER ONE COMMENCES GROUND GEOPHYSICAL SURVEY AT ITS PHOENIX SILVER PROJECT AND ADVANCES CANDELARIA PEA

Silver One Resources Inc. has initiated ground induced polarization and magnetotelluric geophysical surveys on its 100-per-cent-owned Phoenix silver project in Arizona. Both IP and MT are effective electrical geophysical methods useful to detect subsurface metallic minerals, especially disseminated sulphides and structures potentially associated with mineralization. The survey is being conducted by Zonge International Inc. and is designed to test porphyry copper targets on the southern portion of Phoenix silver and to guide future drilling. The fieldwork is expected to be completed in November with a final interpretative report to follow.

These copper targets are strategically located along the northeastern extension of the prolific Miami-Inspiration copper belt. This belt hosts significant deposits and mines such as Rio Tinto-BHP's Resolution deposit to the southwest. Freeport McMoran's Miami and Copper City complexes and BHP's more recent porphyry copper discovery (Ocelot) are on the northeast part of the belt. Miami-Copper City and Ocelot are four kilometres and three kilometres to the southwest of Phoenix silver, respectively (see news releases of Feb. 20, 2025, and July 14, 2025).

The survey is being conducted over the southern portion of Phoenix silver, where a ZTEM airborne electromagnetic survey (see news release of July 14, 2025) outlined two priority geophysical anomalies that are coincidental with hydrothermal alteration and anomalous select rock samples collected from veins, breccia and alteration zones. The select rock samples returned copper and silver values up to 7.7 per cent copper and 1,240 grams per tonne silver (see company news release of June 6, 2024). The IP survey is designed to give better definition to potential mineralized targets at depth.

Silver exploration activities at Phoenix silver

The company continues to advance its silver exploration activities, with a particular focus on the 417 area and the northeast-trending train of silver nuggets (Nuggets North target) located in the northern part of the Phoenix silver property. A detailed gravity survey is planned over the 417 area, which was drilled in 2024. This survey will potentially aid in targeting zones of significant native or sulphide silver mineralization (see the company's news release of Feb. 24, 2025) and assist in prioritizing future drill targets. At the Nuggets North area, the company plans to conduct geological mapping, surface sampling and trenching, subject to permitting by the U.S. Forest Service. Silver One may also conduct detailed gravity over the Nuggets North area if the survey is successful at 417.

Candelaria project update

The company continues to advance its preliminary economic assessment for its Candelaria project. The study is being led by Kappes Cassiday & Associates in collaboration with Independent Mining Consultants Inc. and Paterson & Cooke. The completion of the PEA is anticipated by year-end 2025.

About Silver One Resources Inc.

Silver One is focused on the exploration and development of quality silver projects. The company holds a 100-per-cent interest in its flagship project, the past-producing Candelaria mine located in Nevada. Potential reprocessing of silver from the historic leach pads at Candelaria provides an opportunity for possible near-term production. Additional opportunities lie in previously identified high-grade silver intercepts downdip and potentially increasing the substantive silver mineralization along strike from the two past-producing open pits.

The company owns 636 lode claims and five patented claims on its Cherokee project located in Lincoln county, Nevada, host to multiple silver-copper-gold vein systems, traced to date for over 11 kilometres along strike.

Silver One also owns a 100-per-cent interest in the Phoenix silver project. The Phoenix silver project is a very high-grade native silver prospect that lies within the Arizona silver belt, immediately adjacent to the prolific copper-producing area of Globe, Ariz.

We seek Safe Harbor.
