Silver One Resources Inc. (TSX-V: SVE) (OTCQX: SLVRF) (FSE: BRK1)  announces the analytical results for samples collected in the 2024 diamond drill program completed in the 417 area on its Phoenix Silver Property (Figure 1). The close spaced drill program (average 23 m between vein intercepts) targeted an east-west trending, steeply dipping structure, just upslope from the large (up to 417 pounds) angular vein fragments thought to be derived from these structures (see Figure 2 and news releases of May 15, 2024, and February 5, 2020). With exception of hole 1 that did not intersect the vein, hole 10 (barren) and hole 22 that did not recover core in the vein zone, elevated silver and or base metals (Zn, Pb, Cu), values were encountered in all other holes along the 250 meters of the east-west vein-structure (see Table 1).

The program consisted of 30 core holes from 6 drill pads, totalling 1,955 meters which traced the vein- structures for over 250 m east-west. The drill holes were drilled in HQ size core (63.5mm diameter) with an average depth of 64 m. The best intercept returned 3,800 g/t silver with 0.97% copper over 0.35 m within a quartz breccia (See selected assays in Table 1). This intersection is near the 417 vein fragment area. The presence of silver and base metals along the length of the structure tested suggests this fracture system may still host higher-grade material between or downdip from the drill hole intercepts, as well as elsewhere along the western and eastern extensions of the host structure.

Several other silver and copper exploration targets have been outlined through geological mapping, sampling and the recent ZTEM airborne electromagnetic survey completed by the Company in late 2024 (see Company news release of February 20, 2025). Five silver targets outside the 417 area were identified and two porphyry copper-silver targets were prioritized for additional exploration. The silver target at higher elevations to the north of 417 is of particular importance, as it is characterized by a 1.5 km train comprised of 40 silver fragments weighing up to 9 kg (20 lb) (Nuggets-North Target – Figure 3). Further work on this silver anomaly is highly warranted.

Silver One will look at conducting a close spaced gravity survey over the 417 area to help define the locations of potential concentrations of silver. The gravity survey will examine strong density differences between the host rock (average density of 2.65 – 2.90 gm/cubic centimeter) and concentrations of silver (100% silver has a density of 10.5 gm/cubic cm). This will help in deciding targeting locations of future drill holes. Planned work also includes, mapping and sampling at the Nuggets-North area, as well as induced polarization over the porphyry targets on the southern part of the property, all in preparation for selecting future drill targets.

Greg Crowe, Silver One’s President, CEO and Director, commented, “The results of the 2024 drill program illustrate the continuity of the silver and base metal bearing structures along the 250+ meters of strike tested. The 2024 drill program did not encounter very high-grade intercepts similar to the large angular vein fragments in the 417 area, as these lens-like concentrations of high-grade material may be present between drill intercepts or down-dip of the area tested.  These structures appear to continue westwards towards the Mexican Mine (see Figure 1), where high-grade silver has been historically documented (Arizona Republic, 23 April 1903 originally published in the Globe Times). Several other silver targets were identified though geological sampling and geophysics and need to be further evaluated.

Also, the recently completed airborne ZTEM survey, along with select surface copper and silver rock samples, have identified two high priority copper-silver targets in the southern part of the property (see news release of February 20, 2025, and Figure 3). Phoenix Silver is within a prolific 50+ km long porphyry copper and silver producing belt. Freeport McMoRan’s Miami-Inspiration mining complex and BHP’s new Ocelot porphyry discovery are along strike and lie within 5 km of Phoenix Silver.

The Phoenix Silver property remains highly prospective for both silver vein and porphyry style mineralization. More detailed geophysical and mapping/sampling programs are being considered in preparation for future drilling.”

Table 1. Selected anomalous assays from Phoenix Silver core drilling samples. Intervals reported are near true widths, except for holes 3, 5, 7, 24 (70% to 76% of the intercept), and holes 21 and 23 (25% of the intercept). Anomalous samples over 10 g/t silver are included in table below. Holes not listed contain at least a sample, between 0.15 m and 0.35 m with elevated (over 500 ppm) copper, lead or zinc.

Sampling, Analytical and QA/QC

Seventy-six rock samples from core drilling were collected by Company geologists. All core was drilled in HQ diameter and samples were saw-cut on site after being washed, logged, photographed and analyzed with a portable X-ray pXRF Delta Professional analyzer. One-half was used for wet-chemical analysis and the other half returned to its box for storage at a company facility in Globe, Arizona. Samples varying in size from approximately 1 kg to 11 kg were dropped off by Company personnel at SGS Laboratories (“SGS”) sample preparation facility in Tempe, AZ, thence shipped by SGS personnel to SGS laboratory in Burnaby, BC., Canada (ISO accredited Laboratory, ISO/IEC17025:2017, SCC file # 15919) for analysis. Samples were analyzed by ICP/MS for thirty-four elements with four-acid digestion (SGS code GE.ICP40Q12). Over limit copper, lead and zinc were analyzed by ore-grade four acid digestion ICP (0.5 g sample) code GE.ICP42Q100. Overlimit silver was analyzed by 30 g FA/Gravimetric assay (code GO.FAG37V). Silver One inserted three standards (sourced from OREAS® Certified Reference Material), three blanks and one duplicate in the sample stream. No analytical issues were observed. SGS also inserts blanks, standards and includes duplicate analyses to ensure proper sample preparation and equipment calibration.

About Silver One

Silver One is focused on the exploration and development of quality silver projects. The Company holds 100% 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 down-dip 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 km along-strike.

Silver One also owns a 100% interest in the Silver Phoenix Project. The Silver Phoenix 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, Arizona.
