FIRST MINING CLOSES FIRST TRANCHE OF UPSIZED EQUITY FINANCING

Due to demand, First Mining Gold Corp. has upsized its $5-million non-brokered private placement financing, previously announced on Oct. 26, 2023, to approximately $10-million. The company has closed the first tranche of the offering and issued 63,993,000 units of the company at a price of 12.5 cents per unit for aggregate gross proceeds of approximately $8-million. First Mining expects to close the rest of the offering on or about Dec. 7, 2023.

Each unit consists of one common share of the company and one-half of one common share purchase warrant. Each warrant will entitle the holder thereof to acquire one common share at an exercise price of 20 cents per common share at any time prior to the date which is 36 months following the closing date of the first tranche.

The company intends to use the net proceeds from the offering to advance its Springpole and Duparquet gold projects, as well as for general working capital and corporate purposes.

All of the securities issued under the first tranche are subject to a statutory hold period of four months and one day in accordance with applicable Canadian securities laws. The offering remains subject to the receipt of all necessary regulatory approvals, including the final approval of the Toronto Stock Exchange.
