Core Nickel Announces Assay Results from Winter Drill Program at Halfway Lake and Provides Update on the Mel Deposit
Highlights: Three drillholes along conductive trend HL-04 have returned nickel-bearing sulphide mineralization with grades up to 0.8% Ni over 0.7 m. Nickel mine

About this update from Arizona Eagle Mining Corp.
[{"type":"text","content":" Highlights: Three drillholes along conductive trend HL-04 have returned nickel-bearing sulphide mineralization with grades up to 0.8% Ni over 0.7 m. Nickel mineralization is intersected within massive sulphides indicating the system is capable of concentrating nickel in massive sulphide lenses. Ultramafic-hosted nickel-bearing sulphide mineralization up to 0.65% Ni over 1.1 m indicates a fertile nickel source along conductive trend HL-04. Core Nickel has completed a detailed data validation and 3D geological model of the Mel deposit and received recommendations from Understood Mineral Resources Ltd. to support a modern NI 43-101 resource estimate, including twinning, resampling historical core, and collecting density measurements. Saskatoon, Saskatchewan--(Newsfile Corp. - June 12, 2025) - Core Nickel Corp. (TSXV: CNCO) (\"Core Nickel\" or the \"Company\") is pleased to report nickel-bearing massive sulphide lenses and ultramafic source rocks along conductive trend HL-04 from its winter 2025 Drill Program (the \"Program\") at the 100%-owned Halfway Lake Project (the \"Project\"), located in the Thompson Nickel Belt, Manitoba. The Program comprised a total of 3,585.5 metres (\"m\") in 12 diamond drillholes as outlined in Table 1 and illustrated in Figure 1 as previously announced on April 28, 2025. The Project is strategically located within kilometres of advanced infrastructure such as the Bucko Mill, heavy rail and highways, and access to high-capacity, nearly 100% clean, hydro-electric power. Misty Urbatsch, Chief Executive Officer, President, and Director of Core Nickel, commented, \"Intersecting anomalous nickel mineralization in all three drillholes along the HL-04 trend is an exciting step forward for Core Nickel. The presence of nickel-bearing massive sulphides confirms the system's ability to concentrate nickel, while ultramafic-hosted sulphide mineralization highlights the fertility of this emerging system. At the same time, we're making real strides toward bringing the Mel deposit into a modern resource by systematically resampling historical drill core, digitizing and verifying historical data, and building a modern 3D geological model of the deposit. The next step is getting on the ground and executing the program recommended by Understood Mineral Resources Ltd. to deliver a NI 43-101 compliant resource for Mel.\" F...
