GIGA METALS CONCLUDES 2018 DRILL PROGRAM

Giga Metals Corp. has provided the following 2018 exploration update for its Turnagain nickel-cobalt project.

The company has recently finalized its 2018 fieldwork program, having completed a total of 10,835 metres of core drilling in 40 holes (holes DDH18-267 to DDH18-306).

Giga Metals plans to release all analytical results before the end of the year. ALS Global in North Vancouver is the analytical provider.

"Most of the drilling was conducted to collect data in support of advancing the project to the prefeasibility stage and we believe we now have all the data we need," commented Mark Jarvis, chief executive officer of Giga Metals. "Engineering and metallurgical work is under way, with a target of generating a prefeasibility study by the third quarter of 2019."

The 2018 work program included:

• Two exploration holes totalling 1,119.8 metres in the platinum-enriched Attic zone;
• 13 metallurgical infill holes totalling 3,073 metres within the Horsetrail and Northwest zones of the Turnagain deposit;
• 23 infill holes totalling 5,866.9 metres, all sited between the Horsetrail and Northwest zones to increase sample densities to allow for a reclassification of those portions of the deposit currently categorized as inferred resources to indicated resources;
• Two exploration holes totalling 775.1 metres in the MAG zone, roughly 5.6 kilometres northwest of Horsetrail deposit.

Giga Metals is continuing to advance the project through continuing:

• Consultation with the Tahltan First Nation and Kaska Dena communities;
• Environmental and archaeological studies, including the establishment of remote water and wildlife monitoring stations as well as the re-establishment of surface and groundwater monitoring programs;
• Metallurgical optimization and the Turnagain mine project design engineering studies.

About Giga Metals' Turnagain nickel-cobalt project

The Turnagain project hosts the Horsetrail nickel-cobalt deposit, among the world's largest undeveloped nickel-cobalt sulphide deposits, located in British Columbia, Canada.

Engineering studies are under way with an objective of producing a prefeasibility report by the third quarter of 2019. Extensive metallurgical work indicates a clean concentrate grading 18 per cent nickel and 1 per cent cobalt, which 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 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.
