GIGA METALS ANNOUNCES INCREASE AND AMENDMENT TO NON-BROKERED PRIVATE PLACEMENT

Giga Metals Corp. has agreed to increase the size of its previously announced private placement up to 15 million units for gross proceeds of $1.2-million. Pursuant to the upsized offering, each warrant will now entitle the holder to acquire an additional share at a price of 15 cents per share for a period of 36 months from the date of issuance. Each unit remains at a price of eight cents per unit and comprises one common share of the company and one full share purchase warrant.

The proceeds of the private placement will be used to advance development activities at the Turnagain project and exploration activities at Turnagain focusing on the Attic zone, and for general corporate purposes.

The company anticipates a first closing of the offering on or about April 30, 2026, with a second and final closing of the offering on or about May 15, 2026.

The closing of the private placement is subject to certain closing conditions, including the approval of the TSX Venture Exchange. The company may pay finders' fees in cash or securities to certain arm's-length finders engaged in connection with the private placement, subject to the approval of the TSX-V. The securities issued in the private placement will be subject to a four-month-plus-one-day hold period in accordance with applicable securities laws.
