Giga Metals provides Turnagain project update
(Vancouver, B.C., Canada) – Mark Jarvis, CEO of Giga Metals Corp. (TSX.V : GIGA,
OTCQB: HNCKF) today provided a corporate update on metallurgical and engineering
work focused on Giga’s 100% owned Turnagain nickel-cobalt sulphide project located in
northern British Columbia, Canada.
“We have recently compiled our extensive historical metallurgical work and are currently
conducting a robust variability metallurgical test program using samples from different
parts of the deposit collected during the 2018 drill campaign,” said Mr. Jarvis. “This
information will be incorporated into trade-off studies we are conducting in order to update
the December 2011 Preliminary Economic Assessment (PEA), which we expect to deliver
in the first quarter of 2020.”
Metallurgy
To date, locked -cycle flota tion testing has been conducted at two laboratories on eight
composites, including several locked-cycle tests at Blue Coast Research in 2018. Seven of
the composites yielded high grade nickel concentrates averaging 23% nickel at 52%
recovery. The achievement of successful locked-cycle testing on a variety of samples from
different parts of the Horsetrail deposit represents a major milestone for the project as these
tests provide an important indication of the technical feasibility of the process.
The major focus of the locked-cycle flotation testing has been on composite samples from
three horizontal holes drilled through the heart of the key Horsetrail zone, representing the
expected production for the first several years of operation. Those tests employ ing the
current standard process generally delivered repeatable results with recoveries in the range
of 50-60% and concentrate grades in the range of 18 -22% nickel, for samples ground to
the target size of 80 µm.

Additional tests were previously run on four composite samples sourced from elsewhere
in the resource. These focused on the production of high-grade nickel concentrates. These
yielded excellent concentrate grades, averaging 26% nickel at close t o 50% nickel
recovery. The nickel grade -recovery results of the locked -cycle tests for the seven
composites are shown in the above figure.
The concentrates showed a good purity, with Fe:MgO ratio s from the seven composites
averaging 6.3 with a range of 4.3 to 10.
The detailed review has revealed opportunities for better understanding of the deposit
response through testing a wider variety of metallurgical samples and more focused
attention to modification of flotation reagents and operating conditions.
Metallurgical testing continues at Blue Coast Research on samples collected during the
2018 drilling campaign, including flotation testing of 21 metallurgical variability
samples. The initial round of amenability tests is complete and continues to confirm trends
seen in earlier work, and the test work is now entering an optimization phase. This will be
followed by additional locked-cycle testing on key lithotype composites represent ative of
the deposit resources, and production of a bulk composite concentrate which will be
available as samples to potential strategic partners.

not purely historical, including any statements regarding beliefs, plans, expectations or intentions regarding
the future. Such statements include, but are not limited to, statements with respect to the future financial or
operating performance of the C ompany and its mineral projects, the estimation of mineral resources, steps

future exploration and development of the Project and mineral resource and mineral reserve estima tions
relating to the Project. A number of risks and uncertainties could cause our actual results to differ materially
from those expressed or implied by the forward -looking statements, including: (1) the mineral resource
estimates relating to the Project could prove to be inaccurate for any reason whatsoever, (2) Giga is unable
to finance the Project, (3) prices for nickel and cobalt or project costs make any commercialization
uneconomic, (4) indicated resources may not materialize, (5) permits, environmental opposition, government
regulation or any of many other factors may prevent the Company from commercializing the Turnagain, and
