Objective(s): To better understand the lithological host rocks, mineralization controls and timing of the intrusions at the Colomac Deposit, Goldcrest Deposit and the broader supracrustal rocks that host gold mineralization within the greenstone belt. This added understanding will support further discoveries and advancement to development of the project.

Project Description: This licence has been issued for the scientific research application No.5429. The objective of this research is to better understand the lithological host rocks, mineralization controls and timing of the intrusions at the Colomac Deposit, Goldcrest Deposit and the broader supracrustal rocks that host gold mineralization within the greenstone belt. This added understanding will support further discoveries and advancement to development of the project. The research will rely on the use of fluid chemistry, petrographic characterization, geochemical, and dating mineralization by Re-Os if trace amounts of molybdenite can be identified. Additional work will include whole rock analysis and age dating by Sm-Nd isotope analysis and Lu-Hf isotope analysis of zircons recovered for U-Pg geochronology. The work will commence with training of researches on site during exploration programing, to familiarize the researches with the deposit geology and mineralogy. Samples will be taken from drill core and field samples, field mapping will be completed for spatial relationships. Analytical work will be completed at Lakehead University during the winter seasons. The research updated will be provided by Nighthawk Gold Corp, during community engagement discussion as outlined in the engagement plan aligned with the exploration permit. Researchers will also present the work at the Geoscience forum annually in Yellowknife. The work will be open source and shared with the NT Geological Survey for record. Thesis will be in print and online for public review. The fieldwork for this study will be conducted from May 1, 2023 to December 31, 2023.
