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.

Certain statements in this news release are forward -looking statements, which reflect the expectations of

management regarding the Turnagain Project. Forward-looking statements consist of statements that a re

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

to be taken towards commercialization of the resource, the timing and amount of estimated future production

and capital, operating and exploration expenditures. Such statements are subject to risks and uncertainties

Turnagain to support a Pre -feasibility study and ultimately a Feasibility study, and statements relating to

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

(6) even if the Project goes into production, there is no assurance that operations will be profitable . These
