Giga Metals Provides Update on Carbon Sequestration Studies at
Turnagain Nickel Project
(Vancouver) – Martin Vydra , President of Giga Metals Corp. (TSXV – GIGA) today
provided an update to its CO 2 sequestration research program, being done in conjunction
with Dr. Greg Dipple of the University of British Columbia.
“Further to Elon Musk’s specific call to nickel producers to pursue environmentally
friendly nickel in high volume made during Tesla’s latest earnings call , we are actively
pursuing the development of this large sulphide deposit to meet the future requirements of
EV manufacturers,” said Mr. Vydra.
Dr. Dipple has been studying carbon sequestration in silicate tailings for more than 15 years
at sites including the Mt. Keith nickel mine in Australia and the Diavik diamond mine in
Northern Canada. He has developed a methodol ogy to measure the carbon uptake in
silicate mine residue. Acceptance of his methodology would mean that carbon credits
could be obtained for mine site sequestration of carbon dioxide. Once the silicates convert
to carbonates, the CO2 is locked away for geological time scales.
Ongoing research includes fundamental mineralogical studies to understand the
distribution of relevant minerals within Giga’s Turnagain deposit.
“We have been working with Dr. Dipple for several years now and are looking forward to
the next stage of research, which will involve a large -scale pad test to assess the
atmospheric carbonation of silicates in Turnagain material ,” said Mr. Vydra. “This will
include an assessment of the geomechanical effects of carbonation on this material.”
Previous work by Dr. Dipple has shown that, in addition to CO2 sequestration, cementation
occurs when silicate fines convert to carbonate minerals. This cementation is expected to
stabilize and strengthen residue impoundment facilities , thereby decreasing containment
risk. Upcoming s tudies of the geomechanical effect of carbonation on Turnagain
lithologies could affect mine sequencing and tailings management practices.
“Our goal is to be the world’s first carbon neutral mine.” said Martin Vydra. “We plan to
use power from B.C. Hydro’s clean energy grid, which will involve more capital
expenditure than the alternatives, but is the right thing to do. This exciting research now
underway could help with our goal by providing a way to measure carbon uptake in our
residue.”

“Recent focus on ethical and sustainable development of nickel mines is drawing positive
attention to Turnagain. Over the last several years we have invested significant effort into
engineering a zero carbon footprint mine and we believe the time is right for the industry
to move in this direction.”
