Note: True widths remain undetermined at this stage. All assays are uncut. Further statistical analysis will be required prior to establishing a suitable cut grade.

Nighthawk President & CEO Keyvan Salehi commented, “The latest drill results, combined with results released previously from Grizzly Bear¹ and 24/27² Deposits, demonstrate the immense potential for mineral resource expansion within the Colomac Centre.”

24/27 Deposit

The Colomac Centre Area (please refer to Figure 3 for the Plan View Map) represents a group of five proximal deposits (Colomac Main, Grizzly Bear, Goldcrest, 24/27) in the heart of the Colomac Gold Project. The Company continued to intersect higher-grade intervals from the infill and step-out drilling at the 24/27 Deposit. Nighthawk has identified stacked zones of mineralization, increasing the width of the mineralized corridor, suggesting the potential expansion of the mineral resources in the area. Mineralization continues to remain open in all directions of 24/27 Deposit. Please refer to Figures 1, 4, and 5 for the 24/27 Deposit drilling Isometric, Plan, and Section views, respectively. Please refer to Tables 1 and 2 for the Highlight Drill Assay Results and Drill Assay Results Summary, respectively.

Grizzly Bear Deposit

The Grizzly Bear Deposit is located approximately 800 m southwest of the Colomac Main Deposit. Mineralization at the Grizzly Bear Deposit is hosted in smoky quartz veining in the felsic volcanic porphyry, along the lower contact to the mafic-intermediate volcanics. The current batch of drill results intersected downdip mineralized intervals along the boundary and outside of the pit-constrained Grizzly Bear Deposit 2022 Mineral Resource Estimate³, suggesting the potential expansion of the mineral resources in the area. Please refer to Figures 2, 6, 7, and 8 for the Isometric View, Plan View, Section View #1, and Section View #2 of the Grizzly Bear Deposit drilling, respectively.

Technical Information

The pit shell outlines in Figures 1 to 8 are from the 2022 MRE³ and were completed by InnovExplo Inc. and are defined by a US$1,600/oz gold price assumption.

Nighthawk has implemented a quality-control program to comply with best practices in the sampling and analysis of drill core. Drill core samples were transported in security-sealed bags for analyses at ALS Global Assay Laboratory in Vancouver, BC (“ALS Global”). ALS Global is an ISO/IEC 17025 accredited laboratory. Halved drill core is stored on site and pulps are returned and stored for record.

As part of its QA/QC program, Nighthawk inserts external gold standards (low to high-grade), blanks and duplicates every 20 samples in addition to the standards, blanks, and pulp duplicates inserted by ALS Global.

Qualified Person

John McBride, MSc., P.Geo., Vice President of Exploration for Nighthawk, who is the “Qualified Person” as defined by NI 43-101 for this project, has reviewed and approved of the technical disclosure contained in this news release.
