Silver One Resources Inc. has announced the initiation of ground Induced Polarisation (IP) and Magnetotelluric (MT) geophysical surveys on its 100% owned Phoenix Silver project in Arizona. Both IP and MT are effective electrical geophysical methods useful to detect subsurface metallic minerals, especially disseminated sulfides and structures potentially associated with mineralisation. 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 field work is expected to be completed in November with final interpretative report to follow.
These copper targets are strategically located along the north-eastern 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 4 km and 3 km to the southwest of Phoenix Silver respectively.
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, and Figure 2) 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% copper and 1,240 g/t silver (see Company news release of June 6, 2024). The IP survey is designed to give better definition to potential mineralised 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 (See Figure 2). 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 mineralisation (see Company’s news release of February 24, 2025) and assist in prioritising 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 (PEA) for its Candelaria Project. The study is being led by Kappes Cassiday & Associates, in collaboration with Independent Mining Consultants, Inc. (IMC), and Paterson & Cooke. The completion of the PEA is anticipated by year-end 2025.
