Executive Summary

Giga Metals Corp. announced the commencement of a fully funded, property-scale geophysical survey at its Turnagain Project, a joint venture with Mitsubishi Corporation.
The program utilizes a combined Magnetotelluric (MT) and HeliSAM-EM approach to map the Attic Zone, expanding the exploration focus to include copper, platinum, and palladium alongside the existing nickel-cobalt resource.
The survey covers approximately 6.5 km by 4.5 km, is expected to complete within several weeks, and will directly inform continued exploration activities into the fall of 2026.
The MT survey adds three lines totaling 17 km to continue mapping the geometry of the Turnagain ultramafic intrusive complex at depth.
The EM survey covers 504 line-km to map subsurface conductivity to significantly greater depths than historical surveys.
The program is fully funded by the company, with results guiding exploration into fall 2026.

Material Impact

The news represents a routine, expected follow-up to the February 18, 2026 announcement regarding the spring geophysical program.
It confirms the company is executing on its stated exploration plan without requiring additional immediate capital, which is positive given the company's going concern status noted in the FY2025 MD&A.
The expansion of the exploration target to include copper, platinum, and palladium adds strategic upside potential to the nickel-cobalt focused Turnagain project, aligning with broader critical minerals trends.
The impact is incremental and operational rather than transformative, as the project remains in the exploration/pre-feasibility stage. No new resource estimates, financing, or partnership announcements are included.

Company Overview

Giga Metals Corp. holds an 85% interest in Hard Creek Nickel Corp., which owns 100% of the Turnagain Nickel-Cobalt Project in northern British Columbia.
The project is a joint venture with Mitsubishi Corporation, which holds a 15% stake.
Turnagain is described as one of the world's largest undeveloped nickel-cobalt sulfide deposits, with a 2019 resource estimate of 1.07 billion tonnes of Measured + Indicated resources containing 5.2 billion pounds of nickel.
A Pre-Feasibility Study was completed in September 2023.
The company is also exploring copper, platinum, and palladium potential in the Attic Zone adjacent to the known resource.
An exclusive 10-year agreement with Arca Climate Technologies was signed in January 2026 to evaluate carbon removal potential from ultramafic waste rock and tailings.
