GIGA METALS RELEASES DRILL RESULTS FROM 2018 PROGRAM
Giga Metals Corp. has released analytical results
from 38 of 40 holes drilled in 2018 on the company's Turnagain nickel/cobalt project. The company is
still awaiting assay results from one infill hole and one metallurgical infill hole, and these results will be
announced when received.
As reported Oct. 30, 2018, the 2018 work program included:
- 13 metallurgical infill holes totalling 3,073.0 metres within the Horsetrail and Northwest
zones of the Turnagain deposit;
- 23 infill holes totalling 5,866.9 metres sited between the Horsetrail and Northwest
zones of the Turnagain deposit;
- Two exploration holes totalling 1,119.8 metres in the platinum-enriched Attic zone;
- Two exploration holes totalling 775.1 metres in the MAG zone roughly 5.6 kilometres
northwest of the Horsetrail zone.
"The analytical results reported here further demonstrate the remarkable continuity of mineralization in the
Horsetrail and Northwest zones," said Mark Jarvis, chief executive officer. "We expect the results to allow for the conversion of
significant tonnes from the inferred resource category quoted in our December, 2011, PEA to the indicated
category. The metallurgical infill holes within the proposed starter pits are expected to move some indicated
resources to the measured category. Additionally, the company now has at its disposal several tonnes of
fresh new sample, representative of run-of-mine material, for metallurgical testing."
Technical information
This release provides analytical results from 38 of 40 holes from the 2018 drill program and the Turnagain
project. The drill program, conducted with two skid-mounted drill rigs and one helicopter-supported drill
rig, commenced on July 14, 2018, and ended Oct. 6, 2018.
Metallurgical infill program
The infill drilling program was conducted with two skid-mounted drill rigs in the Horsetrail and Northwest
zones. Although these drill holes provide valuable additional geological and resource modelling
information, their primary purpose was to collect material of appropriate characteristics for future
metallurgical testing. Drill core samples from this program were one-quarter NQ core.

NW: Northwest zone; HT: Horsetrail zone; EOH: end of hole. Metallurgical infill program holes were

Attic zone exploration program
The Attic zone program consisted of two drill holes (DDH18-301 and DDH18-303) in the platinum-
and palladium-enriched Attic zone roughly 3.5 kilometres northwest of the Horsetrail zone. Drill core
samples from this program were one-half NQ core.
DDH18-301 was drilled a few tens of metres below a previously intersected platinum- and palladium-enriched, structurally complex, suite of altered clinopyroxenites. The downhole interval of 238 metres to
260 metres returned an average of 316 parts per billion palladium and 355 ppb platinum at a vertical depth of approximately 185 metres.
DDH18-303 was drilled from the same pad but in an untested northwesterly direction toward, and below,
nearby Davis Creek to test a suspected fault for enrichment. DDH18-303 returned no intervals of note.
MAG zone exploration program
The MAG zone program consisted of two drill holes (DDH18-288 and DDH18-291) in an area of
sedimentary cover rocks with anomalously high total magnetics approximately 5.6 kilometres northwest of
the Horsetrail zone and outside the known Turnagain ultramafic intrusion. Both holes did not penetrate
through the sedimentary cover and returned no intervals of note.
Quality assurance, quality control
Diamond drilling in 2018 was conducted on the Turnagain property using NQ diameter drill rods. Drills
were oriented using a Reflex TN-14 Gyrocompass drill and, after completion of the drill hole, were
surveyed using a Reflex EZ-Gyro. 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 the ALS Minerals preparatory laboratory in Terrace, B.C. The 2018
samples reported herein were analyzed by ALS Global of Vancouver, B.C. Samples were
prepared by crushing the entire sample to 70 per cent passing negative two millimetres, riffle splitting of 250 grams and
pulverizing the split to better than 85 per cent passing 75 micrometres. The core samples also underwent a robust
duplicate assay program that tests rejects and pulps for reproducibility. Samples were also sent to an umpire
lab. Base metal analyses were determined using the ME-ICP61 four-acid digestion method with ICP-AES
finish. Precious metal analyses were determined by PGM-ICP23 fire assay method with ICP-AES finish.
Analytical 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 under way, with an objective of producing a prefeasibility study by the end of 2019. Extensive metallurgical work indicates a clean concentrate grading 18 per cent nickel and 1 per cent cobalt is reliably achievable using simple off-the-shelf processing technology.
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 nickel and cobalt 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.
We seek Safe Harbor.
