Vancouver, British Columbia, September 12, 2025 – Silver X Mining Corp.

Pursuant to the upsized Offering, Red Cloud Securities Inc. (“Red Cloud”), as lead underwriter on behalf of a syndicate of underwriters including Laurentian Bank Securities (collectively, the “Underwriters”), have agreed to purchase for resale 26,000,000 units of the Company (each, a “Unit”) at a price of C$0.50 per Unit (the “Offering Price”).

Each Unit will consist of one common share of the Company (each, a “Common Share”) and one-half Common Share purchase warrant (each, a “Warrant”). Each whole Warrant shall entitle the holder to purchase one Common Share (each, a “Warrant Share”) at a price of C$0.70 at any time on or before that date which is 36 months after the closing date of the Offering.

The Company will grant to the Underwriters an option, exercisable up to 48 hours prior to the Closing Date, to purchase for resale up to an additional 6,000,000 Units at the Offering Price to raise up additional gross proceeds of up to C$3,000,000.

The Company intends to use the net proceeds from the Offering for capital and exploration expenditures related to the Company’s operations in the Nueva Recuperada Silver District in Peru as well as for working capital and general corporate purposes.

Subject to compliance with applicable regulatory requirements and in accordance with National Instrument 45-106 – Prospectus Exemptions (“NI 45-106”), the Units under the Offering will be offered for sale to purchasers resident in all of the provinces of Canada except Québec pursuant to the listed issuer financing exemption under Part 5A of NI 45-106, as amended by Coordinated Blanket Order 45-935 – Exemptions from Certain Conditions of the Listed Issuer Financing Exemption (the “Listed Issuer Financing Exemption”).
