Nighthawk Gold Corp. report assay results from drilling at the Cass Deposit, part of the Kim and Cass Deposits, which are within 15 kilometres of the Colomac Centre Area. The Kim and Cass Deposits are high-grade, potential open-pit deposits that are located within 15 km southwest of the Colomac Centre.

Exploration at the Kim and Cass Deposits focused on understanding the structural controls of the mineralization and expanding the near-surface mineral resources of these deposits. The Cass Deposit is located approximately 2 km southwest from the Kim Deposit. The Cass Deposit area is underlain by subvertical pillowed-to-massive mafic flows and turbiditic meta- sediments which are intruded by gabbroic sills.

The majority of the gold mineralization at the Cass Deposit is hosted along the eastern boundary of the Cass-area gabbro and metavolcanics units and associated with multiple sets of steeply-dipping, quartz-carbonate-sulphide veins. The known mineralization of the Cass Deposit occurs over a 30 m width and a strike length of 960 m. 2022 drilling focused on high-grade, near-surface mineralization to expand the 2022 MRE1 Cass pit-shells. Drilling successfully extended the mineralized zone an additional 150 m on strike to the southwest (approaching the highly prospective Albatross exploration target).

The highest-grade intercept of the drill program (and one of the highest-grade intercepts to-date) was drilled at Cass in hole CM22-22. Approximately 26 of the 39 holes drilled intercepted coarse, visible gold. The pit shell outlines from the 2022 MRE1 and were completed by InnovExplo Inc. and are defined by a USD 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 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.
