VANCOUVER, British Columbia, Oct. 01, 2025 (GLOBE NEWSWIRE) -- Guanajuato Silver Company Ltd. (the “Company” or “GSilver”) (TSXV:GSVR)(OTCQX:GSVRF), a growing Mexican-based precious metals producer, is pleased to announce that as a result of strong investor demand, the Company has entered into an amended letter agreement with Canaccord Genuity Corp. and Red Cloud Securities Inc., as co-lead underwriters and joint bookrunners (collectively, the "Underwriters"), to increase the size of its previously announced “bought deal” public offering from aggregate gross proceeds of C$30,000,000 to C$43,500,000 (the "Upsized Offering"), pursuant to which the Underwriters have agreed to purchase, on a bought deal basis from the Company, 87,000,000 units of the Company (the “Units”) at a price of C$0.50 per Unit.

Each Unit will consist of one common share of the Company (a "Common Share") and one-half of one common share purchase warrant (each whole common share purchase warrant, a "Warrant"). Each Warrant will entitle the holder thereof to acquire one Common Share of the Company at a price of $0.65 for a period of 36 months following the Closing Date (as defined herein).

The Company has granted the Underwriters an option (the "Underwriter Option") to purchase, on the same terms and conditions of the Upsized Offering, up to an additional 13,050,000 Units issued in connection with the Upsized Offering. The Underwriter Option is exercisable, in whole or in part, by the Underwriters at any time until and including 30 days after the Closing Date (as defined herein) of the Upsized Offering. The maximum gross proceeds raised under the Upsized Offering will be $50,025,000 in the event the Underwriter Option is fully exercised.

The net proceeds of the Upsized Offering will be used for sustaining and development capital for the Company’s four operating mines in Mexico, working capital and general corporate purposes.

The Units will be offered by way of a prospectus supplement (the “Prospectus Supplement”) to the Company’s short form base shelf prospectus dated August 21, 2024 (the “Base Shelf Prospectus”) to purchasers in each of the provinces and territories of Canada (other than Québec) and may also be offered by way of private placement in the United States and such other jurisdictions as agreed between the parties.
