Nighthawk President & CEO Keyvan Salehi commented, “The latest drill results from the Colomac Main Deposit, like the other deposits that we have drilled in our district-scale land package, continues to demonstrate the potential for further mineral resource expansion along strike and at depth.”
Colomac Main Deposit
The Colomac Centre Area (please refer to Figure 4 for the Regional Map) represents a group of five proximal deposits (Colomac Main, Grizzly Bear, Goldcrest, 24 & 27) in the heart of the Colomac Gold Project. The latest batch of drill assay results from the Colomac Main Deposit (please refer to Figure 5 for the Local Map of the Drill Hole Locations) focused on the potential north-end (Zones 1.0 and 1.5) and south-end (Zone 3.5) extensions of the deposit along strike. Below is a summary for each of the zones drilled at the Colomac Main Deposit:
- Zone 1.0: Higher-grade, near-surface mineralization (highlighted by hole C22-17) was encountered outside of the 2022 Mineral Resource Estimate1 pit shells, suggesting the potential expansion of known mineralization in that area. Please refer to Figures 3 and 8 for the Isometric and Section #3 Views, respectively, of the highlight drill assay results in Zone 1.0.
- Zone 1.5: The Company encountered wide intervals of mineralization of up to 126 m (highlighted by hole C22-25). New mineralization was also intersected across a fault previously bounding the known mineralization to the south. Please refer to Figures 2 and 7 for the Isometric and Section #2 Views, respectively, of the highlight drill assay results in Zone 1.5.
- Zone 3.5: Nighthawk extended the mineralization zone to the south by approximately 100 m, including higher-grade intercepts. Mineralization continues to be wider at depth like the historical drilling from this area. Mineralization is hosted within traditional quartz diorite but also quartz gabbro, which opens the prospective ground for future exploration to the south. Previous drilling to the south only tested for very shallow mineralization hosted in quartz diorite. Please refer to Figures 1 and 6 for the Isometric and Section #1 Views, respectively, of the highlight drill assay results in Zone 3.5.
Please refer to Tables 1 and 2 for the Highlight Drill Assay Results and Drill Assay Results Summary of the latest batch of drilling at the Colomac Main Deposit.

Technical Information
The pit shell outlines in Figures 1 to 8 are from the 2022 MRE1 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.
