Giga Metals Completes 2022 Geotechnical Field Program

(Vancouver) – Mark Jarvis, CEO of Giga Metals Corp. (TSX.V – GIGA) today announced the

completion of 2022 geotechnical site investigations on the Company’s Turnagain Nickel/Cobalt Project.

The 2022 work program included:

- Five helicopter-supported combination 4” Sonic/HQ geotechnical holes totaling 415 metres

within the proposed tailings storage main and saddle dam alignments.

- Eighteen excavator test pits within the proposed stockpile and waste storage areas.

“The successful acquisition of this geotechnical information will allow us to advance engineering of the

Turnagain project to the Pre -Feasibility level of detail,” said Mr. Jarvis. “ The combination Sonic /HQ

geotechnical drilling allows for the efficient characterization of both overburden and bedrock geotechnical

parameters in support of PFS-level tailings storage facility design. The data collected in this program, when

interpreted alongside the seismic refraction survey conducted in 2021 , will significantly add to our

understanding and will allow for refined tailings storage design engineering. Similarly, the 18 excavator

test pits in the proposed stockpile and waste storage areas complement our existing understanding derived

from prior work in the area.”

About Giga Metals’ Turnagain Nickel-Cobalt Project

The Turnagain Project hosts a significant undeveloped nickel-cobalt sulphide deposit, located in British

Columbia, Canada.

Engineering and metallurgical studies are underway with an objective of producing a Pre-Feasibility study

focused on delivery of nickel and cobalt to the battery cathode supply chain. Extensive metallurgical work

indicates a clean concentrate grading 18% nickel and 1% cobalt is reliably achievable using simple "off -

the-shelf” processing tech nology. Testwork has shown that Turnagain concentrate is amenable to

production of high quality Mixed Hydroxide Precipita tes, a chemical form of nickel and cobalt that is in

high demand from battery manufacturers.

The Turnagain project covers a large, relatively underexplored land package prospective for additional

ultramafic-hosted nickel-cobalt discoveries.

the forward-looking statements. Forward looking statements in this press release include the completion of

a Pre-Feasibility Study.

These forward-looking statements are subject to a variety of risks and uncertainties and other factors that

could cause actual events or results to differ materially from those projected in the forward -looking

information. Risks that could change or prevent these statements from coming to fruition include changing

operational costs for mining and processing; increased capital costs; the timing and content of upcoming

work programs may be interrupted or delayed; geological interpretations based on dri lling that may

change with more detailed information; the availability of labour, equipment, infrastructure and markets

for the products produced; and despite the current expected viability of the project, conditions changing

such that the minerals on our property cannot be economically mined, or that the required permits to build

and operate the envisaged mine cannot be obtained. The forward-looking information contained herein is
