NORTHWEST TERRITORIES – Toronto-based Nighthawk Gold is drilling and finding long and strong gold grades near the former Colomac mine 220 km northwest of Yellowknife, in the Indin Lake greenstone belt. The latest drilling campaign is focused on expanding high grade mineralization, particularly in zone 3.5.

Zone 3.5 lies with the southern part of the Colomac sill, 2.8 km from the high grade zone. 1.5. The best hole was C18-09 that returned 2.24 g/t gold over 68.0 metres, including 3.59 g/t over 32.0 metres, and 5.70 g/t over 6.4 metres.

Nighthawk says drilling to-date has established zone 3.5 as a higher grade domain of strong continuity and expansion potential. The company says there is an association between distinct higher grade plunging domains within more extensive and broadly mineralized zones. This, it says, continues to point to the widespread resource expansion opportunities at Colomac. The higher grade domains defined to date support the likelihood that similar mineralized gold shoots exist along the intrusion’s 9 kilometre strike length.

Details of this year’s drilling campaign are available in the new release dated Sept. 11, 2018 and posted at
