GIGA METALS COMPLETES NON-BROKERED PRIVATE PLACEMENT OF FLOW-THROUGH SHARES

Giga Metals Corp., further to its news release dated March 17, 2026, has closed its previously announced private placement of flow-through shares for aggregate proceeds of $900,000. The company closed on 8,181,818 FT shares at a price of 11 cents.

The flow-through proceeds of the private placement will be used to advance exploration activities at the Turnagain project and any other Canadian properties that the company may acquire, provided that the company will use an amount equal to the gross proceeds received by the company from the sale of the FT shares to incur eligible "Canadian exploration expenses" that will qualify as "flow-through mining expenditures" as such terms are defined in the "Tax Act"; and will be incurred on or before Dec. 31, 2027, and renounced with an effective date no later than Dec. 31, 2026, to the initial purchasers of FT shares.

The securities issued have a hold period expiring four months plus one day after issuance, being July 21, 2026.

In connection with the private placement, the company will pay finders' fees of 8 per cent of the aggregate proceeds raised, payable in common shares of the company. In addition, the company will issue 654,545 finders' warrants. Each finders' warrant will entitle the holder to purchase one common share of the company at a price of 11 cents per common share for a period of one year following the date of issuance, being March 20, 2027.

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