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 /PRNewswire/ - 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).

Drill Summary
Zone 2.0
In 2017, three holes were drilled from a common setup to test
the north-central area of Zone 1.5 to depth. The steepest of the
holes, C17-15C, intercepted 235.05 metres grading 0.99 gpt Au, with
separate internal intercepts of 13.25 metres of 2.06 gpt Au, and
7.75 metres of 2.35 gpt Au (Figure 1; see press release dated
September 18, 2017). The hole was
drilled to a vertical depth of 800 metres and showed that the true
width of the quartz diorite mineralized portion of the sill had
tripled from 50 metres to 155 metres on that section. The reason
for the widening of the mineralized portion of the sill to depth
was not known at the time. It was looked at as either a localized
anomaly or alternatively that large sections of the intrusion do
increase in true width to depth. The C19-39 series holes helped
address this unknown. Hole C19-39B
was collared 270 metres south-southwest of C17-15C to continue
testing the deposit's depth extension marginal to the Zone 1.5 -
Zone 2.0 boundary fault, a subvertical northeast-southwest
(070o) fault that offsets the two zones creating a
slight "dogleg" in the localized strike of the sill (Figure 1, 3).
C19-39B was drilled below previously
reported hole C19-39 (see press release dated October 31, 2019) and successfully extended
mineralization on that section an additional 175 metres to depth by
intersecting 110.50 metres of 1.89 gpt Au, including 57.00 metres
of 2.37 gpt Au, and including 6.40 metres of 5.16 gpt Au, within a
larger 205 metre intersect of near continuous downhole
mineralization, spanning a true width in excess of 110 metres at a
vertical depth of 700 metres (Figure 2).
Drilling on this section has shown 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 is wedge shaped and widens
significantly to depth having a current strike of 500 metres with
its narrowest width of 30 metres at shallow depths but expanding to
upwards of 150 metres at 800 metres vertical depth where it remains
open (Figure
3).
Zone 3.5
Holes C19-38 and C19-38B were
drilled to explore the projected up-plunge extension of Zone 3.5
south of previous drilling in 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 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 hosted by quartz veins
within the basal quartz gabbro phase of the intrusion at 35 metres
vertical depth (Figure 4). Hole C19-38B intersected gold mineralization hosted with
quartz veins within the lower gabbro phase including 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. This is the
first documented occurrence of this type of mineralization below
the quartz diorite upper portion of the sill and represents a new
style of Colomac mineralization that will be followed up on in
Nighthawks 2020 drill program.
Zone 3.0
Hole C19-31 was collared 520 metres northeast of the C19-38
holes to explore the central portion of Zone 3.0, an area that had
seen limited drilling in the past (Figure 1). It was intended to
follow-up on and undercut mineralization reported in hole C12-14C
of 6.75 metres of 13.24 gpt Au, including 1.10 metres of 80.13 gpt
Au (see press release dated October 10,
2012) to a vertical depth of 320 metres. Although the hole
traced the mineralization to greater depth it did not encounter
similar grades.
Holes C19-32 and C19-32B were
drilled 110 metres northwest of C19-31 to explore an area in the
sill to shallow depth that had never been drilled (Figure 1).
C19-32 intersected mineralization at less than 200 metres from
surface returning 16.45 metres of 1.39 gpt Au, including 10.00
metres of 1.62 gpt Au, and including 3.40 metres of 2.55 gpt Au.
Hole C19-32B was successful in
extending mineralization an additional 130 metres to depth where it
remains open.
Hole C19-36 was spotted 150 metres north of the C19-32 holes to
explore an area that had never been drilled (Figure 1). It
intersected sporadic grade over its length including 1.0 metres of
16.20 gpt Au; 12.65 metres of 1.04 gpt Au, including 3.00
metres of 2.55 gpt Au; 6.00 metres of 3.07 gpt Au, including 3.00
metres of 4.91 gpt Au, and including 1.50 metres of 6.57 gpt Au;
and 0.50 metres of 11.80 gpt Au. A 250-metre-long gap in drilling
exists north of hole C19-36 where historical holes only tested the
sill to less than 100 m depth. This
250-metre-long gap contains several near-surface historical
higher-grade intercepts that will be further investigated during
the Company's 2020 exploration program.
Technical Information
Nighthawk has implemented a
quality-control program to comply with best practices in the
sampling and analysis of drill core. Drill core samples were
transported in security-sealed bags for analyses at ALS Global
Assay Laboratory in Vancouver, BC ("ALS
Global"). ALS Global is an ISO/IEC 17025 accredited
laboratory. Pulp and metallics assaying for gold was conducted on
the entire pulverized sample.
As part of its QA/QC program, Nighthawk inserts external gold
standards (low to high-grade) and blanks every 20 samples in
addition to the standards, blanks, and pulp duplicates inserted by
ALS Global.

Forward-looking information includes, but is not limited to,
information with respect to the Company's continued exploration
programs (including size and budget) and the ability to advance
targets and the timing and results thereof; and the ability to
expand the current resource at Colomac with additional drilling.
Generally, forward-looking information can be identified by the use
of forward-looking terminology such as "plans", "expects", or "does
not expect", "is expected", "budget", "scheduled", "estimates",
"forecasts", "intends", "anticipates", or "does not anticipate", or
"believes" or variations of such words and phrases or state that
certain actions, events or results "may", "could", "would",
"might", or "will be taken", "occur", or "be achieved".
Forward-looking information is based on the opinions and
estimates of management at the date the information is made, and is

prices, changes in foreign exchange and interest rates, actual
results of current exploration activities, government regulation,
political or economic developments, environmental risks, permitting
timelines, capital expenditures, operating or technical
difficulties in connection with development activities, employee
relations, the speculative nature of gold exploration and
development, including the risks of diminishing quantities of
grades of reserves, contests over title to properties, and changes
in project parameters as plans continue to be refined as well as
those risk factors discussed in Nighthawk's annual information form
for the year ended December 31, 2018,
