TORONTO, November 21, 2025 -- Galantas Gold Corporation (TSX-V & AIM: GAL; OTCQB: GALKF) ("Galantas" or the "Company") is pleased to announce that, as a result of strong investor demand, the Company has agreed with Canaccord Genuity Corp. and Haywood Securities Inc. (together, the "Agents") to increase the size of its previously announced "best efforts" private placement of units of the Company (each, a "Unit") to raise aggregate gross proceeds of up to C$13.5 million (the "Offering"), consisting of 168,750,000 Units at a price of C$0.08 per Unit (the "Offering Price"). The size of the over-allotment option (the "Agents' Option") granted to the Agents will be upsized to permit the Agents to raise up to an additional C$2,025,000 through sales of up to 25,312,500 additional Units at the Offering Price.

Each Unit will be comprised of one common share of the Company (each, a "Common Share") and one Common Share purchase warrant (each, a "Warrant"). Each Warrant will entitle the holder thereof to acquire one Common Share at a price of C$0.12 for a period of 36 months from the closing of the Offering.

As compensation for their services, the Company will pay to the Agents a cash commission equal to 7.0% of the aggregate gross proceeds of the Offering (including gross proceeds from the Agents' Option, if any), subject to reduction to 3.0% of the gross proceeds of up to C$1,100,000 (increased from C$500,000 as previously announced) from purchasers on the president's list to be agreed between the Company and Canaccord Genuity Corp. (the "President's List"), and the Company will issue to the Agents compensation warrants ("Compensation Warrants") in an amount equal to 7.0% of the Units sold in the Offering (including Units sold pursuant to the Agents' Option, if any), subject to reduction to 3.0% for purchasers on the President's List. Each Compensation Warrant will entitle the holder thereof to acquire one Common Share for the Offering Price for a period of 24 months from the closing date of the Offering.

The net proceeds from the Offering will be used to fund exploration work on the Indiana Project (as defined below), to fund Option Payments (as defined below) in respect of the Indiana Project, and for general corporate and working capital purposes.

There is no minimum amount of Units that must be sold in the Offering as a condition to its completion. Completion of the Offering is expected to occur on or around December 10, 2025, and is subject to obtaining the required approvals of the TSX Venture Exchange (the "TSXV") and satisfaction of customary closing conditions.

Any subscriber that becomes an insider of the Company will file a personal information form with the TSXV for their review and approval. The Warrants will restrict any holder from exercising any Warrants that would result in any holder owning or controlling 20% or more of the then issued and outstanding Common Shares (calculated on a partially diluted basis).
