Giga Metals Corp. Announces Receipt for Final Prospectus

Vancouver, April 20, 2021 - Giga Metals Corp. (TSXV: GIGA) announces today that it has obtained a receipt (the "Receipt") from the BC Securities Commission for the final short form prospectus in connection to the Company's previously announced overnight marketed public offering of units (the "Offered Units") of the Company. The Offered Units include non-flow through units priced at $0.45 comprised of one common share and one warrant, and flow through units priced at $0.51 comprised of one flow through common share and one warrant. Each warrant will entitle the holder thereof to purchase one non-flow through common share at a price of $0.60 at any time on or before the date which is 36 months after the closing date.

The Company announces it also intends to complete a concurrent non-brokered private placement of units which will have substantially the same terms and conditions as the Offered Units issued in the Offering, except that the non-brokered units will be subject to a hold period of 4 months and a day. The private placement will yield gross proceeds of up to C$750,000.

As a result of obtaining the Receipt, closing of the Offering is anticipated to be on Friday, April 23, 2021. A copy of the short form prospectus is available on SEDAR at www.sedar.com.

This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Units in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of that jurisdiction.

On behalf of the Board of Directors,
