Nighthawk Extends Broad Mineralized Zones to New Depths at Colomac

INTERCEPTS 124.50 METRES OF 1.12 GPT AU, INCLUDING 13.50 METRES OF 3.60 GPT AU, AND INCLUDING 4.75 METRES OF 7.64 GPT AU

TORONTO, Oct. 31, 2019 /PRNewswire/ - Nighthawk Gold Corp. ("Nighthawk" or the "Company") (TSX: NHK) is pleased to provide the results for five drillholes (2,862 metres) completed on Zones 1.5 and 2.0 of the Colomac Main Sill, part of the Colomac Gold Project ("Colomac") centrally located within its Indin Lake Gold Property, Northwest Territories, Canada. Drilling has provided additional evidence for the merger of high-grade Zone 1.5 with the northern part of Zone 2.0 and extended this broad panel of mineralization to new depths below previously reported intersections. Current drilling has established continuity over significant widths with a pathway for expansion along strike and to depth. The Company has now reported results for 49 drillholes (18,902 metres) of the 91 drillhole (35,018 metre) 2019 program at Colomac.

Three of the five holes were drilled to test the deposit's depth extension marginal to the Zone 1.5 - Zone 2.0 boundary fault, a subvertical northeast-southwest (070^o) fault that offsets the two zones creating a slight "dogleg" in the localized strike of the sill (Figure 1). All holes intersected extensive mineralization with C19-35 returning 124.50 metres of 1.12 gpt Au, including 13.50 metres of 3.60 gpt Au, and including 4.75 metres of 7.64 gpt Au; and hole C19-39 returning 118.50 metres of 1.57 gpt Au, including 32.50 metres of 2.62 gpt Au, and including 7.75 metres of 5.10 gpt Au (Table 1).

Dr. Michael Byron, President and Chief Executive Officer said, "These latest holes have been instrumental in demonstrating that wide panels of mineralization with strong continuity exist to depth, lateral to the boundary fault that separates Zones 1.5 and 2.0. This extensive domain of higher-grade mineralization appears to span the two zones and possibly postdates the fault as it shows no indication of fault disruption or diminution. Drilling of the Colomac Main Sill continues to document cohesive zones of mineralization uninterrupted to depth with relatively uniform distribution. We are confident that these characteristics highlight Colomac's impressive growth potential as a bonafide multi-million-ounce deposit."

Colomac Drilling Highlights:

Zone 1.5

• Hole C19-35 tested an area to depth immediately north of the boundary between high-grade Zone 1.5 and Zone 2.0 and intersected 124.50 metres of 1.12 gpt Au (70 metres true width), including 13.50 metres of 3.60 gpt Au, and including 4.75 metres of 7.64 gpt Au, extending mineralization on this section to 530 metres depth where it remains open.

Zone 2.0

• Hole C19-39 was drilled on the same section as previously reported holes C19-24 (see press release dated July 31, 2019) and the C17-06 series holes (see press release dated July 13, 2017). Hole C19-39 intersected 118.50 metres of 1.57 gpt Au (65 metres true width), including 32.50 metres of 2.62 gpt Au, and including 7.75 metres of 5.10 gpt Au. Mineralization on this section spans from near surface to depth in excess of 550 metres where it remains open.
  
  
• Hole C19-37 undercut previous hole C17-10B (see press release dated August 24, 2017) and intersected 35.75 metres of 1.26 gpt Au (22 metres true width), including 12.60 metres of 2.29 gpt Au, and including 8.00 metres of 2.70 gpt Au, extending mineralization on this drill section to a depth of 450 metres where it remains open.
  
  
• The panel of mineralization that spans Zone 1.5 and 2.0 extends upwards of 400 metres in strike, to a depth of 570 metres, and remains open in both dimensions.

Drill Summary

Zone 2.0

Two holes were drilled within the northern section of the zone immediately south of the Zone 1.5 - Zone 2.0 boundary fault to test mineralization to depth, below previously drilled holes that returned wide intercepts within the top of the sill (Figure 1). Hole C19-37, the southernmost of the two, was drilled on the same section as C17-10B which intersected 86.30 metres of 1.45 gpt Au, including 23.30 metres of 1.98 gpt Au, and including 8.40 metres of 3.03 gpt Au (see press release dated August 24, 2017). C19-37 encountered two broad gold intercepts with an upper intersection of 31.50 metres of 1.02 gpt Au, and a lower main intersection of 35.75 metres of 1.26 gpt Au, including 12.60 metres of 2.29 gpt Au, and including 8.00 metres of 2.70 gpt Au, successfully extending mineralization on this section an additional 180 metres to a depth where it is now in excess of 450 metres and open in all directions (Figure 2).

Hole C19-39 was collared 50 metres north of C19-37 to extend mineralization previously reported in holes C17-06, 06B, and 06C (see press release dated July 13, 2017), and hole C19-24 (see press release dated July 31, 2019). The C17-06 series holes were among the first drilled into the resource gap between Zones 1.5 and 2.0 to test for the possible convergence of the two zones into a larger higher-grade domain. C19-24 was drilled on the same section as the C17-06 holes and extended the domain an additional 40 metres to depth, intersecting 56.25 metres of 2.76 gpt Au, including 13.00 metres of 3.51 gpt Au gold, and including 4.25 metres of 14.89. Hole C19-39 was collared 50 metres west of C19-24 to drill deeper on this section and intersected two broad gold intercepts; an upper section of 51.75 metres of 1.37 gpt Au, including 10.00 metres of 2.35 gpt Au, and an 8.25 metres of 2.43 gpt Au, and a lower main section that returned 118.50 metres of 1.57 gpt Au, including 32.50 metres of 2.62 gpt Au, and including 7.75 metres of 5.10 gpt Au (Figure 3). C19-39 successfully extended mineralization on this section to a vertical depth in excess of 550 metres, where it remains open. Hole C19-39B was drilled 100 metres below C19-39 but results are pending.

Drilling to-date within the gap region between Zones 1.5 and 2.0 shows continuity between the zones and has established that the collective domain now extends upwards of 400 metres in strike to a depth of 570 metres and remains open.

Zone 1.5

C19-35 was collared 110 metres from C19-39 just north of the boundary fault (Figure 1). It was drilled to undercut the previously reported intersect in hole C19-17 of 58.50 metres of 1.93 gpt Au, including 13.55 metres of 4.58 gpt Au, and including 4.55 metres of 10.26 gpt Au (see press release dated September 5, 2019). Hole C19-17 was one of several holes that explored the zone's southern extension and infilled an area 70 metres south of hole C19-08, which recorded the project's best intercept to-date of 56.00 metres of 13.49 gpt Au, including 30.50 metres of 22.12 gpt Au, and including 16.50 metres of 34.18 gpt Au (see press release dated May 28, 2019). Hole C19-35 tracked 100 metres below C19-17 intersecting 124.50 metres of 1.12 gpt Au, including 13.50 metres of 3.60 gpt Au, and including 4.75 metres of 7.64 gpt Au, extending mineralization to a depth of 530 metres on this section where it remains open (Figure 4)

Holes C19-33 and C19-33B lie 450 metres north of C19-35 (Figure 1). These shorter holes tested a region above the plunge of Zone 1.5 in an area that had never been drilled to depth, to determine if the top of the plunging zone extends closer to surface. Although both holes reported intersections, they were not typical of the zone's higher-grade nature, indicating that the well-mineralized part of the zone is much deeper on this section.

Assay results are pending for the remaining 50 drillholes (18,543 metres) of the 2019 drill program including drilling on the Colomac Main Sill, the Goldcrest Sill, and Treasure Island.
