Giga Metals Releases Drill Results From 2021 Program
(Vancouver BC) – Mark Jarvis, CEO of Giga Metals Corp. (TSX.V – GIGA) today announced analytical
results from 15 holes drilled in 2021 on the Company’s Turnagain Nickel/Cobalt Project.
The 2021 work program included:
- Nine NQ resource infill holes totaling 4,214 metres within the Horsetrail and Northwest
zones of the Turnagain deposit.
- Six HQ geotechnical holes totaling 2,082 metres sited on the margins of Horsetrail and
Northwest zones of the Turnagain deposit to support pit engineering design.
- Seismic refraction survey in Flat Creek Valley in support of tailings management engineering
design.
“The infill drilling is focussed on later years in the mine li fe, at the edges of the pit design in our 2021
PEA,” said Mr. Jarvis. “The drilling was designed to allow for conversion of resources from the Inferred to
the Indicated category , and we have not seen any surprises. The geotechnical holes within the propose d
ultimate pit provided valuable geotechnical information and, where ultramafic rocks were intersected, are
expected to move some Indicated resources to the Measured category. Additionally, the Company now has
acquired valuable geotechnical and hydrogeological data with which to advance the project engineering.”
Technical Information
This release provides analytical results from 15 holes from the 20 21 drill program and the Turnagain
Project. The drill program, conducted with two skid-mounted drill rigs, commenced on June 30, 2021 and
ended October 12, 2021.
Resource Infill Drilling Program
The infill drilling program was conducted with one skid-mounted drill rig in the Horsetrail and Northwest
zones in areas of Inferred resources. Drill core samples were one-half NQ core.

Geotechnical Drilling Program
The geotechnical drilling program was conducted with one skid-mounted drill rig in the Horsetrail and
Northwest zones. Although these drill holes provide valuable additional geological and resource modeling
information, their primary purpose was to investigate the geotechnical characteristics of the proposed pit
wall areas with oriented core and optical televiewer, and to conduct hydraulic conductivity packer tests and
install vibrating wire piezometers to guide engineering design . Where ultramafic rocks were intersected
drill core samples from this program were one-half HQ core.

Seismic Refraction Survey
The seismic refraction survey was conducted by Frontier Geosciences from September 7, 2021 to October
6, 2021 in support of engineering design for the proposed Turnagain Mine tailings storage facility and had
three main objectives: to estimate overburden t hickness, to estimate overburden characteristics, and to
estimate depth to water table. Information gathered will be used to select sites for sonic and diamond drilling
to further characterize geotechnical characteristics for tailings storage design.
Quality Assurance, Quality Control
Diamond drilling in 2021 was conducted on the Turnagain property using both NQ and HQ diameter drill
rods. Drills were oriented using a Reflex TN-14 Gyrocompass and, after completion of the drill hole, were
surveyed using a Reflex EZ-Gyro. NQ core samples were ½ core collected using a hydraulic core splitter,
while HQ core samples were ½ core collected with a diamond core saw. Giga Metals systematically
inserted certified reference materials (standards) and blanks into each batch of samples at regular intervals.
Samples were placed in sealed bags and shipped directly to SGS Canada Ltd.’s laboratory in Burnaby ,
British Columbia. Samples were prepared by crushing the entire sample to 75% passing 2 millimetres, riffle

splitting of 250 grams and pulverizing the split to 85% passing 75 micr ometres. The core samples also
underwent a robust duplicate assay program that tests rejects and pulps for reproducibility. Approximately
10% of samples were also sent to a check lab, Saskatchewan Research Council Geoanalytics Laboratories
(SRC) (previously TSL Labs). Base metal analyses were determined using the four-acid digestion method
with ICP-AES finish. Precious metal analyses were determined with the fire assay method with ICP-AES
finish. A nalytical results are verified with the application of industry standard Quality Assurance and
Quality Control (QA/QC) procedures.

About Giga Metals’ Turnagain Nickel-Cobalt Project
The Turnagain Project hosts the Horsetrail nickel -cobalt deposit, 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.
Extensive metallurgical work indicates a clean concentrate grading 18% nickel and 1% cobalt is reliably
achievable using simple "off -the-shelf" processing tech nology. The Turnagain project covers a large,
relatively underexplored land package prospective for additional ultramafic -hosted nickel -cobalt
discoveries. Turnagain is one of the few projects in a stable jurisdiction that can potentially deliver large
quantities of cobalt and nickel to meet the growing needs of the electric vehicle
and energy storage markets at a time when many research analysts are projecting there will be shortages in
the cobalt and nickel required by battery manufacturers.
