GIGA ANNOUNCES START OF EXPLORATION SEASON

Giga Metals Corp. has begun its 2018 exploration program at the Turnagain nickel-cobalt project located in north-central British Columbia. Archeological and wildlife surveys are under way. One drill rig is on the site and a second will arrive shortly.

Highlights:

• 9,600 metres of core drilling planned with two drill rigs;
• Several high-impact exploration targets to be tested;
• Infill, metallurgical and geotechnical drilling to support prefeasibility studies;
• Geophysical surveys and trenching to define new targets.

"We are very excited about getting back into the field at Turnagain," said Mark Jarvis, president and chief executive officer of Giga Metals. "The improving market for cobalt and nickel as part of the battery supply chain means that now is the time to advance our deposit to prefeasibility. Our goal is to have the project shovel-ready by 2021."

High-impact exploration targets include three unexplained magnetic anomalies. Project geologists hypothesize that the lower portions and roots of the Turnagain magmatic complex were displaced by faulting.

"We are interested in determining whether these unexplained magnetic anomalies represent the roots or feeder conduits to the Turnagain complex," continued Mr. Jarvis. "Since the feeder zones of intrusive complexes can contain accumulations of massive sulphides, such a discovery at Turnagain could be transformative."
