Giga Metals Announces Positive Geophysical Results
(Vancouver, BC, Canada) - Scott Lendrum, CEO of Giga Metals Corp. (TSX-V: GIGA; OTCQB:
GIGGF; FSE: BRR2) today announced receipt of results from the recent Magnetotelluric (MT)
geophysical survey at Turnagain, interpreted by Matthew Penney, President of Hardrock
Geophysics.
Highlights:
• Geophysics program completed on underexplored Attic Zone
• MT exploits resistivity contrast to map geometry of ultramafic intrusive complex
• Data supports up-facing structural orientation, untested basal contact
Figure 1: The initial MT lines were positioned over the large copper-in-soils anomaly in the Attic
Zone, which is also prospective for PGE mineralization.
“This is the first step of a methodical program exploring for copper, platinum and palladium in the
Attic Zone of the Turnagain ultramafic complex,” said Mr. Lendrum. “The MT worked well in this
environment to define geometry and reveal previously unknown features.”
“MT is the perfect tool to exploit the strong resistivity contrast between the ultramafic complex and
the surrounding sedimentary rocks to a significant depth,” said Dr. Stephen Beresford, who is
advising on the exploration program. “We now have a high degree of confidence that the Turnagain
intrusion geometry is in-place and up-facing, that the basal contact is untested, and the marginal
contacts are untested to any significant depth.”

This supports the interpretation that the intrusive is in its original, upright position. The basal
contact is untested, and marginal contacts are mostly untested.

airborne EM did not penetrate deeply enough to register the previously unknown low resistivity
anomaly, which will require further investigation.
“Dr. Beresford has recommended further MT lines to delineate the intrusive geometry to the
northwest and southeast to constrain the search volume for further work,” said Mr. Lendrum.
“These will be followed by EM surveys to help prioritize the drill targets. Our recently completed
financing will fund this geophysical program into the Spring of 2026.”
About Giga Metals Corporation
Giga Metals Corporation’s core asset is the Turnagain Project, located in northern British
Columbia, which contains one of the few significant undeveloped sulphide nickel and cobalt
resources in the world. Turnagain is held in Hard Creek Nickel, a subsidiary owned jointly by Giga
Metals Corporation and Mitsubishi Corporation. The Pre-Feasibility Study was released in October
2023.
The Turnagain ultramafic complex is also prospective for copper, platinum and palladium
mineralization in the Attic Zone, an area adjacent to the known nickel resource.
