GOLD: Nighthawk expands Colomac as well as Goldcrest

NORTHWEST TERRITORIES – Toronto-based Nighthawk Gold Corp. has received the final results from the summer 2016 program at the Colomac gold project 220 km northwest of Yellowknife in the Indin Lake greenstone belt. The results have allowed the company to further expand the Colomac gold zones and validate the continuity at depth of the nearby Goldcrest mineralization.

Nighthawk drilled the Colomac zone 3.0 and the narrow gap between it and zone 2.5. Hole C16-10 expanded zone 3.0 to the north and to a depth of 200 metres below surface, intersecting 20.18 metres grading 1.80 g/t Au, including 4.53 metres at 2.73 g/t and 7.40 metres at 2.30 g/t. Hole C15-10B, drilled at a steeper angle, cut 14.20 metres grading 1.42 g/t Au and 9.02 metres at 0.74 g/t.

At the nearby Goldcrest deposit, the company tested for broad, near surface, high grade zones both north and south of the 2014 drill program. Hole G16-10 intersected 26.05 metres of 2.16 g/t Au, including 3.75 metres of 12.39 g/t, and separate intercepts of 6.30 metres of 3.04 g/t and a 11.05 metres of 1.57 g/t. The same hole confirmed the continuity of the mineralization at  depth from 202 to 287 metres. Hole G16-07 returned 9.00 metres grading 3.10 g/t Au, including 5.25 metres of 4.98 g/t. Undercut hole G16-07B intersected multiple gold intervals including 12.70 metres of 1.67 g/t Au, including 7.45 metres of 2.51 g/t and 3.25 metres of 4.41 g/t, and a further 12.65 metres at 1.58 g/t, including 3.65 metres of 4.86 g/t. The latter two holes show characteristics of a possible high-grade gold zone, including proximity to a transverse fault, multiple 10+ metre gold intercepts, and the occurrence of several high-grade gold values, according to Nighthawk.

The Colomac gold deposit was discovered in 1945, but didn’t pour its first gold until 1990. The mine closed the following year, but was reopened under new ownership in 1994. It was closed again in August 1997.
