"With the completion of the second and final tranche of our private placement, Giga Metals is well-funded to advance exploration at Turnagain," said chief executive officer Scott Lendrum.

This funding sets the stage for a productive 2026."

The proceeds of the private placement will be used for general corporate purposes and the company's exploration program.

No control blocks were created as a result of the private placement.

Further to the news release dated July 2, 2025, Giga is settling an aggregate of approximately $63,250 in debt through the issuance of common shares to be issued at a deemed price of 10 cents per common share.
