Continues to Advance Candelaria Towards Pre-Feasibility
Vancouver, BC – May 12, 2026 – Silver One Resources Inc. (TSX-V: SVE; OTCQB: SLVRF; FSE: BRK1) (“Silver One” or the “Company”) reports that it has completed the core drilling, auger drilling, and airborne geophysical ZTEM survey previously announced in its news releases dated March 2, February 23, and May 4, 2026. The Company is also pleased to provide an update on ongoing geotechnical, metallurgical, and exploration programs at its Candelaria Silver Project in Nevada. These activities are key components of the Company’s Pre-Feasibility Study (“PFS”) currently in progress, and are designed to support engineering design, resource conversion and future permitting.
Greg Crowe, President and CEO of Silver One, commented: “Candelaria continues to advance on multiple fronts, and I am pleased to report the progress across our technical programs is on schedule and very encouraging. The completion of heap-leach pad auger drilling and geotechnical work positions us well for the upcoming PFS. The district-scale ZTEM will help guide the definition of new exploration targets across this large, highly prospective silver system. With drilling for resource expansion and testing new targets set to begin later this month, and a second rig arriving in July, we are entering an exciting phase of growth as we work to unlock the full potential of Candelaria.”
Geotechnical Core Drilling for PFS Pit Design
Geotechnical drilling required for pit-slope-stability analysis in the PFS has been completed. This work will inform open-pit design which will include potential pushbacks and the integration of the two existing open pits into a single, larger pit configuration. Core logging, structural interpretation, and laboratory testing are currently in progress. A total of 1,873.7 metres in 9 holes was completed along the margins of the proposed open-pit footprint (see Figure 1).
Core Drilling for Additional Metallurgical Testing
Two HQ-diameter (63.5 mm) holes totaling 489.2 metres were drilled for metallurgical testing. One hole (SO-C-26-194) was drilled in the Mount Diablo pit to supplement existing information. A second hole (SO-C-26-195) was drilled at Northern Belle where only historic silver and gold recovery information was available (see Figure 1). Kappes Cassiday & Associates (“KCA”) will conduct cyanide-leach bottle-roll and column tests on representative samples of the entire mineralized zone of each drill hole.
Auger Drilling of Historic Heaps Completed
The auger drilling program across the historic leach pads has also been completed. A total of 1,414 metres were drilled in 56 holes, 32 in leach pad 1 (LP1) and 24 in leach pad 2 (LP2). The program was designed to:
- upgrade portions of the heap-leach resource from the Inferred category to the Measured and Indicated (“M&I”) categories; and
- collect representative material for upcoming pilot-scale metallurgical testing.
Sample preparation and analytical work are underway, with results to be incorporated into an updated resource model.
ZTEM Airborne Electromagnetic Survey Completed
The Company has completed a property-wide ZTEM airborne electromagnetic survey. The survey is intended to:
- identify shallower manto-style and structurally controlled silver systems along strike and down-dip of the current open pits; and
- evaluate potential deeper porphyry-style targets at depth.
Processing and interpretation of the ZTEM data are underway by Geotech Ltd. These results will be integrated with previous airborne magnetics, ground IP, and rock geochemical datasets to refine and prioritize future drill targets. Final interpretations are expected by the end of June. Read Full Silver One PDF Here
