SILVER ONE REPORTS FILING OF TECHNICAL REPORT TO MINERAL RESOURCE
ESTIMATE ON ITS CANDELARIA PROJECT, NEVADA
Candelaria’s project resources (from open-pit, underground, stockpiles and heap-leach pads) now
total 108.18 million ounces of silver equivalent in the Measured and Indicated categories, and 29.46
million ounces of silver equivalent in the Inferred category
Vancouver, British Columbia--(June 19, 2025) - Silver One Resources Inc. (TSXV: SVE) (OTCQX: SLVRF)
(FSE: BRK1) (“Silver One” or the “Company”) is pleased to announce it has filed on SEDAR a National
Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43 -101”) technical report (the
“Technical Report”) with respect to the Candelaria Project (the “Project”), located in Nevada, USA. The
Technical Report titled “ Mineral Resource Estimate on the Candelaria Property” dated April 30, 2025,
prepared by James A. McCrea, P. Geo, supports the initial mineral resour ce estimate (“MRE”) at the
Project (see news release dated May 6, 2025).
Highlights:
• Mount Diablo and Northern Belle pit-constrained resources:
o Measured and Indicated (M&I) resource of 22,070,000 tonnes averaging 94 g/t Ag and
0.20 g/t Au, for 66.754 million ounces of silver and 141,400 ounces of gold, or 70.84
million ounces of silver equivalent (“AgEq”) (see note ˧ in table 1).
o Inferred resource of 2,960,000 tonnes averaging 68 g/t Ag and 0.18 g/t Au, for 6.462
million ounces of silver and 17,000 ounces of gold (7.00 million oz AgEq).
• Underground Measured and Indicated resource of 1,200,000 tonnes averaging 168 g/t Ag and
0.27 g/t Au, for 6.45 million ounces of silver and 10,200 ounces of gold (6.50 million oz AgEq).
• Underground Inferred resource of 650,000 tonnes averaging 150 g/t Ag and 0.24 g/t Au, for
3.136 million ounces of silver and 5,100 ounces of gold (3.15 million oz AgEq).
• Candelaria’s project resources (from open-pit, underground, stockpiles and heap-leach pads)
now total 108.18 million ounces of silver equivalent in the Measured and Indicated categories,
and 29.46 million ounces of silver equivalent in the Inferred category.

Table 1. Candelaria in-ground, underground, and stockpiles mineral resource estimates.
Totals above include pit Constrained Mineral Resources (Mt. Diablo and Northern Belle) at a US$9.273
NSR cut-off, within a US$27.50/oz Ag optimized engineered pit (“design pit”) (see footnotes and Resource
Estimate Details section below).
1. A Mineral Resource is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or
quality and quantity that there are reasonable prospects for eventual economic extraction.
An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of lim ited
geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.
An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a
Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with
continued exploration.

An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics
are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation
of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling an d testing
and is sufficient to assume geological and grade or quality continuity between points of observation.
An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to
a Probable Mineral Reserve.
2. Mineral resources, which are not mineral reserves, do not have demonstrated economic viability. The estimate of mineral resources has no
known issues and does not appear materially affected by any known environmental, permitting, legal, title, socio -political, marketing, or other
relevant issues. There is no guarantee that Silver One will be successful in obtaining any or all of the requisite consents, permits or approvals,
regulatory or otherwise for the project or that the project will be placed into production.
3. The mineral resources in this study were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (‘CIM’), CIM Standards
on Mineral Resources and Reserves, Definitions and Guidelines prepared by the Standing Committee on Reserve Definitions and adopted by the
CIM Council on May 10, 2014.
4. This Mineral Resource Estimate for the near -surface material is based on material within an optimized open pit shell that results from a
US$27.50/oz silver price revenue factor. Tonnes and grade reported at $27.50/oz Ag and U$2,106/oz Au.
5. The Mineral Resource Estimate for underground material was calculated using a 90 g/t Ag(T) cut-off below the $27.50 Pit and using a 70%
mining recovery.
6. Total Ag (AgT) and Au (AuT) mean total silver and gold assays (FA/Gravity) reported by the lab. It also means Calculated silver and gold values
for historic samples collected by previous operators that were assayed for cyanide soluble silver or gold only, but not assayed for total gold and
silver. Average total silver and gold for Mt. Diablo, Northern Belle and Underground resources in this table are derived from silver and gold assays
in a database that consists of up to 80% of cyanide soluble silver and gold assays only. Approximately 20% of the assays in the database have both
FA and or gravity total silver and gold values. The latter constitutes the basis for the generation of the Calculated silver and gold values using
regression formulas developed by qualified Silver One professionals.
The Technical Report is available for review on SEDAR+. Readers are encouraged to read the Technical
Report in its entirety, including all qualifications, assumptions and exclusions that relate to the mineral
resource estimate. The Technical Report is intended to be read as a whole, and sections should not be
read or relied upon out of context.

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.
