Giga pauses Brazilian Drill Program

(Vancouver) – Mark Jarvis, CEO of Giga Metals Corp. (TSXV – GIGA) (OTCQX –

HNCKF) announced today that the drill program on its 16,858-hectare Corrente property

in the state of Piaui, Brazil, has been temporarily suspended due to weather. Flooding in

the area has subsided, but water tables have remained too high for effective drilling. The

exploration program is expected to resume in February 2022.

Prior to the suspension of drilling, three (3) holes were drilled (GG-PD-01, GG-PD-02 and

GG-PD-03) for a combined meterage of 322 metres (m). Hole 01 and 0 3 achieved their

targeted depths (125m and 120m respectively) while Hole 02 was abandoned at a depth of

77m due to excess water volume and pressure.

To date, 50 samples representing 1 .0m vertical sample intervals from selected zones of

interest have been submitted to the ALS facility in Belo Horizonte, Brasil for copper and

multi-elemental analysis.
