Silver One Expands Exploration for High-Grade Silver at Phoenix Silver

MWN-AI** Summary

Silver One Resources Inc. has announced its plans to enhance exploration efforts at its 100% owned Phoenix Silver Project located in Arizona. The company will initiate a comprehensive drone-borne magnetometry and ground-penetrating radar (GPR) survey, focusing on the 417 area previously drilled in 2024, where significant high-grade silver veins were discovered, yielding intersections of up to 3,800 g/t silver and 0.97% copper over a length of 0.35 meters. Notably, while the drilling targeted specific vein structures, it did not uncover the significant native silver mineralization observed at the surface, warranting further investigation.

The magnetometry survey intends to identify linear features such as structures and veins associated with silver mineralization, enhancing knowledge of potential sources of the precious metal within the area. In tandem, GPR technology will be employed to map subsurface structures, metallic masses, and to locate historical mine workings, potentially unlocking further exploration targets.

Should the results of these surveys prove favorable, Silver One may adopt a gravity survey to optimize drilling targets. Additionally, the company has plans to extend geophysical work into the Nuggets North area, where large silver fragments have already been identified.

As part of its ongoing exploration strategy, Silver One is also undertaking induced polarization and magnetotellurics surveys to target porphyry copper deposits within the property. With these innovative geophysical techniques, the company aims to refine its understanding of the subsurface conditions and enhance its exploration endeavors, potentially leading to valuable discoveries within the Phoenix Silver Project.

MWN-AI** Analysis

Silver One Resources Inc. (TSXV: SVE) is taking a proactive approach to exploring its Phoenix Silver Project in Arizona through a combination of advanced geophysical technologies. The initiation of drone-borne magnetometry and ground penetrating radar (GPR) surveys indicates a commitment to refining exploration strategies aimed at uncovering high-grade silver deposits.

The previously drilled 417 area yielded promising intersections, indicating noteworthy potential, but the presence of high-grade silver fragments suggests that there may be more elusive deposits beneath the surface. The upcoming geophysical surveys could prove pivotal in delineating structures associated with these fragments, potentially leading to more targeted drilling.

For investors, this is a critical juncture. Should the surveys validate the anticipated mineralization and lead to successful drilling results, the stock may experience upward momentum due to heightened interest and confidence in the project’s prospects. Specifically, the detection of native silver pockets could significantly enhance the attractiveness of the Phoenix Silver Project, contributing to a more favorable valuation of Silver One.

Additionally, the Company’s historically rich Candelaria Mine in Nevada, as well as the promising Nuggets North area, present further avenues for exploration and production. These factors, coupled with the ongoing induced polarization and magnetotellurics (IP/MT) surveys in the property’s southern region, offer a multifaceted investment narrative.

While investing in exploration companies carries inherent risks, the strategic application of innovative geophysical methods at Silver One presents an intriguing opportunity. Investors should closely monitor the results of the forthcoming surveys and be prepared to act on the implications, especially if they translate into economically viable silver mineralization. Diversification in precious metals, particularly amidst ongoing economic uncertainty, could also enhance portfolio resilience.

Utilizing Drone-Borne Magnetometry and Ground Penetrating Radar

Vancouver, British Columbia--(Newsfile Corp. - December 16, 2025) - Silver One Resources Inc. (TSXV: SVE) (OTCQX: SLVRF) (FSE: BRK1) ("Silver One" or the "Company") is pleased to announce that it is commencing a detailed drone-borne magnetometry survey and a ground-penetrating radar ("GPR") survey at its 100%-owned Phoenix Silver Project in Arizona. The surveys will cover the 417 area, previously drilled in 2024, as well as the historic Mexican Mine located approximately 600 meters to the west (see Figure 1).

Drilling conducted in 2024 intersected targeted vein structures in the 417 area that returned intersections of up to 3,800 g/t and 0.97% copper over 0.35 m (see company news release dated February 24, 2025). The program however, did not encounter the massive native silver mineralization represented by the high-grade silver fragments observed near surface. Extremely high-grade silver pockets are likely to occur as lenses and shoots within mineralized structures and their detection may be better outlined with the upcoming geophysical surveys. With this additional geophysical information, the Company is attempting to refine the location of potential silver bearing drill and/or trenching targets.

The magnetometry survey is designed to delineate linear features such as structures, veins and dikes potentially associated with silver mineralization. These features are interpreted as possible sources of the high-grade silver fragments previously discovered in the 417 area. The main 417 structure heads westwards towards the old Mexican Mine, which will also be tested with these surveys.

Ground-penetrating radar has been successfully applied in mineral exploration to map near-surface lithium pegmatites, banded iron formations, laterites, bauxites, and other deposits (Jan Francke Published Works https://groundradar.com/resources/published-works; groundradar.com/resources/documents; and groundradar.com/services/resource-exploration/lithium-pegmatites). At Phoenix Silver, the GPR may detect metallic masses, map subsurface structures, and identify historic mine workings such as those at the old Mexican Mine. These insights will help guide exploration and define drilling and/or trenching targets.

GPR is an electromagnetic method that employs wavelengths on the scale of decimeters to meters, similar to common radio waves. It measures variations in the electrical properties of the ground. Metals are strong reflectors, but air and water within tunnels, as well as changes in lithology, can also produce reflections. The primary challenge lies in transmitting energy into the ground: if the soil cover is highly conductive, radar waves are attenuated near the surface, limiting penetration. Depth of penetration can range from a few meters up to 100 meters in favorable conditions. However, even within established applications such as laterites and bauxites, penetration depth and radar suitability can vary significantly.

Future Work

Should the results of these surveys prove positive, the Company will evaluate the use of a gravity survey to further refine drilling targets. In addition, Silver One may extend this geophysical work to the Nuggets North area, where abundant silver fragments (up 40 cm long, 25cm wide and 15cm thick and over 20 kg in weight) have been collected across a broad zone (see Figure 2 and Company news release dated February 20, 2025).

Induced polarization and magnetotellurics ("IP/MT") surveys targeting porphyry copper targets in the southern portion of the property are ongoing, with final results anticipated in early 2026.

About Silver One

Silver One is focused on the exploration and development of quality silver projects. The Company holds a 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.
