Nighthawk Gold Corp. ("Nighthawk") (TSX VENTURE:NHK) reports assay results from the final 7 of 20 holes (Figure 1) drilled by Royal Oak in 1997 on Nighthawk's 100%-owned Colomac Gold Property ("Colomac Gold Project") in the Northwest Territories ("NWT"). The 20 historic holes (7,470 metres) are now eligible to be included in an updated resource estimate. These results have collectively confirmed the higher grade character of Zone 3.5, verified its continuity to depth, and suggested the existence of similar mineralization in Zone 3.0 located along strike to the north. (See December 11, 2012 and January 16, 2013 news releases for the released assays on the previous 13 holes.)
In two previous news releases (December 11, 2012 and January 16, 2013), assay results for the other 13 historic holes were reported from the central high-grade shoot of Zone 3.5 and its southern extension. The results reported in this news release, representing 2,110 metres, tested the northern extension of Zone 3.5 and beneath Zone 3.0 - located 300 metres north of Zone 3.5 along the Colomac sill.
Historical holes drilled in Zone 3.5 and Nighthawk's sub-vertical hole, C12-15 - drilled from the sill's top to base intersecting 203.40 metres of 2.49 g/t gold, including 25.75 metres of 7.78 g/t gold, have collectively confirmed the existence of a well-constrained, steeply plunging high-grade gold shoot to a minimum vertical depth of 950 metres.
Contoured gold assays from Zone 3.5 shown in the section through the high-grade gold shoot (Figure 2) clearly outline the geometry and continuity of a 50-metre wide body of gold mineralization. Moreover, at least five additional shoots have been identified over a 3.0 kilometre strike length between Zones 3.5 and 2.0, the true widths of which range from 50 metres (Zone 3.5) to 110 metres (Zone 2.0). Shoot identification is based on previous shallow drilling; however, additional drilling to depth is required for further delineation.
David Wiley, Nighthawk's President and CEO, commented, "The potential to expand the gold resource at these and other prospective areas of the Colomac Gold Project remains high. We will continue advancing the project in 2013 and are looking forward to our next stage of drilling."
