GIGA METALS ANNOUNCES NON-BROKERED PRIVATE PLACEMENT

Giga Metals Corp. has arranged a non-brokered private placement of a unit offering in the company, for aggregate gross proceeds of up to $1-million, at a price of eight cents per unit.

Each unit will consist of one common share of the company and one non-transferable share purchase warrant. Each whole warrant will be exercisable into one common share of the company at an exercise price of 15 cents, for a period of two years from the closing of the private placement.

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

Closing is anticipated to occur on or about May 5, 2026, and 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 hold period in accordance with applicable securities laws.

It is expected that certain directors and officers of the company may participate in the offering. The participation of insiders in the offering will constitute a related party transaction within the meaning of Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transactions. The company anticipates relying on exemptions from the minority shareholder approval and formal valuation requirements applicable to the related party transactions under sections 5.5(a) and 5.7(1)(a), respectively, of MI 61-101, as neither the fair market value of the securities to be acquired by the participating insiders nor the consideration to be paid by such directors and officers is anticipated to exceed 25 per cent of the company's market capitalization.
