NORTHWEST TERRITORIES – Toronto-based Nighthawk Gold completed almost 16,000 metres of drilling this summer at its Colomac gold project 220 km northwest of Yellowknife in the Indin Lake greenstone belt. The company says it continues to intersect broad zones of mineralization with higher grade centres.

This year rather than focus on the northern half of the sill, Nighthawk tested several prospective targets between zones 2.0 and 3.5. The best hole from zone 3.0 was 2.98 g/t gold over 20.1 metres, including 4.30 g/t over 13.3 metres and 9.54 g/t over 5.0 metres.

Zone 2.5 where three holes were drilled returned 51.0 metres of 1.68 g/t gold, including 8.3 metres of 3.17 g/t and 1.8 metres of 9.81 g/t; 26.0 metres of 2.04 g/t gold, including 11.4 metres of 3.00 g/t and 3.3 metres of 6.61 g/t; and 53.0 metres of 1.48 g/t gold, including 20.8 metres of 2.59 g/t and 1.5 metres of 12.03 g/t.

At zone 2.0 three holes assayed as follows: 25.3 metres of 3.42 g/t gold, including 12.8 metres of 5.05 g/t and 7.25 metres of 7.10 g/t;  39.5 metres of 1.54 g/t gold, including 10.5 metres of 3.07 g/t and 2.5 metres of 6.76 g/t; and 15.6 metres of 2.48 g/t gold, including 9.0 metres of 4.00 g/t and 3.75 metres of 8.34 g/t.

Nighthawk concludes that the Colomac property has the potential for more steeply plunging gold zones developing at depth and laterally extensive, shallow high grade mineralization open at depth.
