Mr. Mark Jarvis reports

ANTHONY MILEWSKI APPOINTED TO BOARD OF DIRECTORS

Giga Metals Corp. has appointed Anthony Milewski, chairman and chief executive officer of Cobalt 27 Capital Corp., to the board of Giga Metals. Cobalt 27 owns a 2-per-cent net smelter return royalty on nickel and cobalt at Giga's Turnagain project in British Columbia.

"We are assembling a very strong team at Giga Metals," commented Mark Jarvis. "Anthony has created, in Cobalt 27, the premier battery metals streaming and royalty company. His knowledge of the institutional market and the strategic players in this space is without parallel. We are very excited to welcome him to the board of Giga Metals."

"As battery chemistries continue to evolve, nickel is emerging as one of the most critical basic materials in the lithium ion battery," commented Mr. Milewski. "The experience of the nickel industry around HPAL [high-pressure acid leach] laterite projects has been costly, and the need to develop low-capex [capital expenditures] nickel sulphide deposits with proven technology is acute. Giga Metals has a very large sulphide nickel and cobalt project that we think has an excellent chance of getting developed and built this market cycle.

"The Turnagain project is competitive with the other large Class 1 greenfields nickel projects of the world in terms of: world-class jurisdiction; project economics; simplicity of processing; low capex relative to HPAL; and of the exceptional quality of concentrate that can be produced. It is also of great interest to note that research at the University of British Columbia, partially supported by Giga Metals, shows the real possibility that the Turnagain project could be carbon neutral due to CO2 [carbon dioxide] sequestration in the residue produced during concentration. I envision the team building a carbon-neutral and environmentally friendly mine in a world-class mining jurisdiction."

Comments relating to project economics and capex are based on the Turnagain project preliminary economic assessment, which was prepared by AMC Mining Consultants and dated Dec. 2, 2011.

Mr. Milewski is the founder, chief executive officer and chairman of Cobalt 27. He has served as a member of the London Metal Exchange cobalt committee and has deep experience in the mining industry as a director, adviser, founder and investor. In 2016, one of the industry's leading publications, The Mining Journal, named him as a future mining leader. Mr. Milewski was a member of the investment team at Pala Investments Ltd. Prior to joining Pala Investments, he worked at Firebird Management LLC.

Mr. Milewski previously worked at Renaissance Capital and Skadden, Arps, Slate, Meagher & Flom LLP in Moscow, where he focused on advisory and transactional work in the metals and mining sector as well as the oil and gas sector. He has lived and worked in Africa and Russia, including a year as a Fulbright scholar, and has spent considerable time in Central Asia.

Mr. Milewski holds: a BA in Russian history from Brigham Young University; an MA in Russian and Central Asian studies from the University of Washington; and a JD from the University of Washington. He also holds an LLM from the Russian Academy of Sciences.

Resignation of director

Phillip Robinson has resigned from the board of Giga Metals, effective immediately. Mr. Robinson is a member of the investment team at Pala Investments and has served on the board of Giga Metals since November, 2017. The company wishes to thank Mr. Robinson for his service.

Grant of incentive stock options

Pursuant to its stock option plan, which was approved by the TSX Venture Exchange, the company will be granting one million stock options to various directors and consultants. The options are exercisable at 20 cents per share and expire on April 29, 2024.

About Giga Metals' Turnagain nickel-cobalt project

The Turnagain project hosts the Horsetrail nickel-cobalt deposit, a significant and undeveloped nickel-cobalt sulphide deposit located in British Columbia, Canada.

Engineering and metallurgical studies are under way, with an objective of advancing the project to the prefeasibility level. Extensive past metallurgical work and current metallurgical work indicate that a clean concentrate grading 18 per cent to 25 per cent nickel is reliably achievable using a very simple "off-the-shelf" comminution and froth flotation process flowsheet.

The Turnagain project covers a large, relatively underexplored land package that is 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.
