Nighthawk Drilling at Colomac Confirms Widening of its Two Best Mineralized Zones to Depth

INTERCEPTS 110.50 METRES OF 1.89 GPT AU (UNCUT), INCLUDING 57.00 METRES OF 2.37 GPT AU, AND INCLUDING 6.40 METRES OF 5.16 GPT AU

TORONTO, Dec. 3, 2019 /CNW/ - Nighthawk Gold Corp. ("Nighthawk" or the "Company") (TSX: NHK; OTCQX: MIMZF) is pleased to report assay results for seven drillholes (2,685 metres) completed on Zones 2.0, 3.0 and 3.5 of the Colomac Main Sill, part of the Colomac Gold Project ("Colomac") centrally located within its Indin Lake Gold Property, Northwest Territories, Canada (Table 1). Hole C19-39B at Zone 2.0 shows the continued widening of the mineralized portion of the sill to depth, where the true width has grown to more than 110 metres at vertical depths of 700 metres below surface. This hole was drilled approximately 270 metres to the south of the deepest intersection at Zone 1.5 (hole C17-15C), where drilling in 2017 showed a similar widening of the mineralized portion of the sill to 155 metres in true width (see press release dated September 18, 2017).

The newly defined panel of mineralization, formed by the merger of high-grade Zone 1.5 with the northern part of Zone 2.0, has now been traced approximately 500 metres in strike with its narrowest width of 30 metres at shallow depths but expanding to upwards of 155 metres at 800 metres vertical depth where it remains open (Figure 3).

Two holes drilled at the southern end of Zone 3.5 within a previous unexplored area, have intersected shallow high-grade mineralization outside and west of the quartz diorite portion of the sill. These intercepts represent a new style of Colomac mineralization that will need to be further explored in 2020.

Additional results pending includes: assay results for the remaining 32 drillholes (12,210 metres), from the Colomac Main Sill and the Goldcrest Sill (to date a total of 59 drillholes for 22,808, metres have been released); assay results for the remaining 9 holes (2,796 metres) at the Treasure Island Gold Project (to date 10 holes for 3,018 metres have been released); final cyanide leach metallurgical test results for Colomac (bottle roll and column test); and regional prospecting and mapping exploration results.

Dr. Michael Byron, President and Chief Executive Officer said, "We were very pleased to confirm that the widening of the sill does not appear to be an isolated feature, but that the entire Zone 1.5 - Zone 2.0 mineralized panel resembles a wedge form that widens significantly to depth. We believe that the dimensions of this mineralized panel will have a positive impact on our resource growth and has opened the door for exciting new exploration opportunities at Colomac." Colomac Drilling Highlights: Zone 2.0

• C19-39B was drilled below previously reported hole C19-39 (see press release dated October 31, 2019), and intersected 110.50 metres (55 metre true width) of 1.89 grams per tonne gold ("gpt" "Au"), including 57.00 metres (25 metre true width) of 2.37 gpt Au, and including 6.40 metres of 5.16 gpt Au, extending mineralization an additional 175 metres below C19-39 (Figures 1, 2).

• C19-39B intersected 205 metres of near continuous downhole mineralization generating a true width greater than 110 metres. Mineralization on this section spans from near surface to over 700 metres vertical depth where it remains open.

• The wedge-shaped panel of mineralization formed by the merger of Zone 1.5 with the northern section of Zone 2.0 spans upwards of 500 metres in strike (Figure 3). Although its narrowest true width of 30 metres occurs at shallow depths, it expands to upwards of 150 metres at 800 metres vertical depth where it remains open.

Zone 3.5

• Holes C19-38 and C19-38B tested the southern extension of Zone 3.5's shallow mineralization south of previous drilling within an unexplored area of the sill (Figure 1). Both holes intersected shallow high-grade mineralization hosted by quartz veins located outside and west of the quartz diorite upper portion of the sill.

• Hole C19-38 intersected 11.20 metres of 4.41 gpt Au, including 6.60 metres of 7.09 gpt Au, and including 3.75 metres of 12.19 gpt Au, while hole C19-38B intersected 9.00 metres of 1.94 gpt Au including 5.25 metres of 3.04 gpt Au, and 6.00 metres of 3.24 gpt Au including 3.00 metres of 6.24 gpt Au, representing a new style of Colomac mineralization (Figure 4).
