Giga Metals to Exit Copper Exploration Project in Brazil

(Vancouver) – Mark Jarvis, CEO of Giga Metals Corp. (TSX.V – GIGA) announced

today that Giga will discontinue its greenfields copper exploration activities in Piaui State,

Brazil.

“Our exploration activities in Brazil have not generated enough encouragement to justify

continued allocation of budget and effort,” said Mr. Jarvis. “We will keep our focus on

advancing our core asset, the Turnagain nickel project.”

Since early 2021, Giga Metals, has conducted several reconnaissance and follow -up

exploration programs across a 40kHa exploration land package along the southern

perimeter of the Parnaiba Sedimentary Basin in southern Piaui State, Northeast, Brazil.

This work was done via its wholly owned subsidiary Giga Brazil.

Exploration included remote sensing, reprocessing of regional magnetic and radiometric

geophysical data, stream sediment sampling and reconnaissance percussion drilling

targeting potentially economic “Kupferschiefer-style” sediment hosted c opper

mineralization, examples or which were known to occur in this remote, under -explored

region of Brazil.

FORWARD LOOKING STATEMENTS

Statements in this document which are not purely historical are forward looking statements,

including any statements regarding beliefs, plans, expectations or intentions regarding the future.

Forward looking statements in this news release include the Brazil project is prospective for copper,

the Company’s plans to undertake exploration activities at the Brazil Project and expend funds on

it. It is important to note that the Company's actual business outcomes and exploration results could

differ materially from those in such forward looking statements. Risks and uncertainties include

that Giga may not be able to fully finance exploration at the Project, including drilling; our initial

findings at the Project may prove to be unworthy of further expenditure; commodity prices may

not support exploration expenditures at the Project; and economic, competitive, governmental,

environmental and technological factors may affect the Company's operations, markets, products

and share price. There are geopolitical risks because the Project is located in Brazil. Even if we

explore and develop the Project, and even if copper or other metals or minerals are discovered in

quantity, the project may not be commercially viable. Additional risk factors are discussed in the

Company's latest Management Discussion and Analysis which is available under Company's
