Giga Metals to Support Research into

CO2 Sequestration

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

that Natural Resources Canada (NRCan) has agreed to be part of a consortium of

government agencies and industry partners, including Giga Metals Corp. (TSX.V - GIGA),

that have agreed to f und a research initiative investigating carbon dioxide (CO 2)

sequestration in silicate mine residue, including ultramafic residue from mineral deposits

such as Giga Metals’ Turnagain nickel-cobalt deposit located in British Columbia. A total

of $3.5 million has been committed to the project, including $2 million from NRCan with

the balance from other government geoscience agencies and from industry.

“We are proud to support this research as an industry partner,” said Mark Jarvis, CEO of

Giga Metals. “More than a decade of research by project lead Dr. Greg Dipple has shown

that silicate mineral residue, when exposed to the atmosphere, absorbs CO2 and converts it

to carbonate minerals, and the CO2 would remain locked in the carbonates over geological

time scales. There is a real possibility that the Turnagain project, if developed into a mine,

could achieve our goal of being carbon neutral.”

Government support for the research initiatives includes geoscience agencies across

Canada, including NRCan, Geoscience B.C., the B.C. Geological Survey, and the

Geological Survey of Canada . Industry support for the research is being provided by

companies including Giga Metals, First Point Minerals and De Beers Group.

“The level of support we are seeing from both government and industry is very encouraging

and is enabling the start of field pilot tests of our technology,” said project lead Dr. Greg

Dipple of the Bradshaw Research Initiative for Minerals and Mini ng at the University of

British Columbia. “Giga Metals, in addition to financial support, will be providing residues

from their metallurgical test program which is currently underway. We will be

investigating the rate of CO 2 uptake from these samples as we ll as co -benefits such as

cementation which could stabilize residue impoundment and reduce dust in the residue.”
