NICKEL NORTH COMMENCES 2026 SUMMER EXPLORATION PROGRAM AT HAWK RIDGE CU-NI-PGE SULFIDE PROJECT

VANCOUVER, BC -- July 10, 2026 Nickel North Exploration Corp. ("Nickel North" or the "Company")

(TSX-V: NNX) is pleased to announce that its 2026 summer field exploration program has officially

commenced during the first week of July at the Company's 100% owned Hawk Ridge Cu-Ni-Co-PGE

Sulfide Project in Northern Quebec.

The Hawk Ridge Project encompasses 411 mineral claims covering a total area of 179.67 km Superscript 2 along a

highly prospective 50 km long magmatic sulfide belt. Field crews mobilized swiftly, and initial phases

of geological mapping, geochemical sampling, and passive seismic geophysics are already well

underway across the major known mineralization zones.

Key Exploration Highlights from Early July Operations: dot Surface Soil Geochemical Sampling: The field team has successfully completed 100 surface soil sampling over two high-priority target areas (Figure 1). All samples have been securely bagged and are being transported to Vancouver for immediate portable X-Ray Fluorescence (XRF) analysis to guide ongoing field targeting.

dot Targeted Rock Sampling & New Mineralization Zone Discoveries: Prospecting and bedrock sampling have focused on the North Hopes Advanced, Pio, and Sindler Gamma zones. A new mineralized zone outcropping with strong Cu-Ni mineralization and alteration within the North Hopes Advanced target areas have been discovered by the field crew. The new zone is about 500m long and > 20 m wide which has been mapped and sampled. A total of 35 mineralized rock samples have been dispatched via air cargo to Vancouver for formal assaying.

dot Historical Core Relogging & Re-Assaying: A total of 106 mineralized core samples (Figure 3) and 60m unsampled mineralized cores from 4 historical holes from previous drilling campaigns have been systematically relogged and sampled. These historical samples have been shipped via air cargo to Montreal and are being submitted to a local certified commercial laboratory for comprehensive re-assaying. tonyguo@nnexploration.com www.nnexploration.com

dot Passive Seismic Geophysical Surveys: The geophysics crew has completed 4 lines of Short- Period Receiver Function Technique (SFRT) passive seismic surveying, totaling around 3500 linear meters. The survey lines directly intersect the core mineralized trends and historical aeromagnetic pipe-like anomalies at Pio, Sindler-Gamma, Fold and Bay, and Hopes Advanced Zones. Raw geophysical data will be processed and interpreted over the coming weeks to evaluate deeper structural extensions of the sulfide bodies and the pipe-like magnetic anomalies.

Tony Guo, CEO of Nickel North, commented: "Kicking off our field operations early in the season is a tremendous achievement for the team. By deploying this focused, science-first strategy, we can systematically unlock value across several prominent targets within the broad Hawk Ridge footprint while keeping a sharp eye on our capital expenditure. Moving forward, these incoming datasets-- spanning geochemistry, assays, and passive seismic profiles--will directly shape the geometry of our upcoming diamond drilling campaign, which we intend to launch in 2027-2028. Investors can look forward to consistent updates as these results filter back from the labs and contact company late." tonyguo@nnexploration.com www.nnexploration.com
