About Nighthawk

Nighthawk is a Canadian-based gold exploration company with 100% ownership of a district-scale land position within the Indin Lake Greenstone Belt, located approximately 200 km north of Yellowknife, Northwest Territories, Canada. Nighthawk has advanced its flagship asset Colomac, outlining a robust project with current Indicated Resources of 25.89 Mt with an average grade of 2.01 gpt Au for 1.67 Moz of gold and Inferred Resources of 5.71 Mt with an average grade of 2.03 gpt Au for 0.37 Moz of gold, with the majority of ounces contained within an underground resource. Near-term resource expansion opportunities exist proximal to the current resources, and additional upside exists throughout the +7km strike length of the host quartz diorite with a substantial opportunity at depth where the true width is known to expand significantly across a 3.5km-long section. Within this largely underexplored Archean gold camp, the Company has identified a number of high-priority targets within large regional deformation zones that are pregnant with gold mineralization and are known to host significant deposits which warrant additional exploration and follow-up.

The Company has an experienced and dedicated team with a track record of successfully advancing projects and is well funded and supported to complete its goals and objectives.
