TSX: NHK
TORONTO, Sept. 5, 2019 /PRNewswire/ - Nighthawk Gold Corp.
("Nighthawk" or the "Company") (TSX: NHK) is
pleased to provide an update on the latest drill results from both
its flagship Colomac Gold Project ("Colomac") and the
Treasure Island Gold Project ("Treasure Island"), located
within the north central region of its 100% owned Indin Lake Gold
Property, Northwest Territories,
Canada. Results for nine holes (4,276.89 metres) drilled at
Colomac's Zone 1.5 and two holes (690 metres) recently completed at
Treasure Island are reported
(Table 1, Figures 1, 4).
Dr. Michael Byron, President
and Chief Executive Officer said, "We are excited to resume our
drilling program at Treasure
Island and to follow up on our very successful 2018 program
which delivered many noteworthy intercepts and discoveries. We
consider Treasure Island as one of
our key regional prospects and given that its extensive broad
mineralized envelope hosts internal higher-grade domains, we
believe that we are well on our way to realizing a first-class
asset to compliment Colomac. Focused activities continue at
Colomac, as we test the deposit around hole C19-08, Colomac's best
intercept on record, and to explore the northern margins of Zone
1.5. We are well on track to exceed last year's record of 32,500
metres drilled, and project that this year we will meet or exceed
40,000 metres. 2019 has been an exceptional year so far and we
eagerly await the remaining drilling and regional exploration
results and their expected new discoveries."
Drilling Highlights:
Colomac Zone 1.5
- Hole C19-17 tested an area 70 metres south of C19-08 (Colomac's
best intercept to-date, see press release dated May 28, 2019), returning 58.50 metres of 1.93
grams per tonne ("gpt") gold ("Au") (32.00 metres true width),
including 13.55 metres of 4.58 gpt Au gold, and including 4.55
metres of 10.26 gpt Au.
- Hole C19-21 was drilled 30 metres south of C19-17 and
intersected 62.25 metres of 1.47 gpt Au (33.00 metres true
width), including 19.25 metres of 2.20 gpt Au, and including
6.00 metres of 2.65 gpt Au and 6.75 metres of 2.80 gpt Au.
- Forty-seven drillholes have now been reported for Colomac
representing 17,100.89 metres of the 2019 drilling to-date. All
holes have intersected mineralization.
Treasure
Island
- Hole T19-01 intersected 6.25 metres of 12.08 gpt Au,
including 2.50 metres of 28.61 gpt Au, and T19-01B reported an upper intersect of 27.25
metres of 1.41 gpt Au, including 9.25 metres of 2.37 gpt Au, and
including 3.50 metres of 4.21 gpt Au, and a deeper intersect of
6.50 metres assaying 10.20 gpt Au, including 3.75 metres of
16.38 gpt Au, effectively extending the western boundary of the
Main Zone.
- T19-01 and T19-01B intersected
mineralization west of all previous drilling and tracked the zone
from surface to 200 metres vertical depth, earmarking its western
extension as being wide open for further expansion.
- Drilling has defined the system as being upwards of 200 metres
wide and 700 metres long, where it remains largely open along
strike and to depth.
- Nineteen holes (5,814 metres) have been drilled at Treasure Island in 2019 of which two are
presented. Assay results for the remaining seventeen holes will be
released as they become available.

Drill Summary
Colomac Zone 1.5
The recently completed holes at Colomac Zone 1.5 focused on
exploring the zone's northern extension both at shallow levels and
to depth, and infilled areas south of the project's best intercept
to-date, hole C19-08 (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). Three holes were drilled south of hole C19-08 to test
areas laterally at depth of the high-grade intercept. Hole C19-17
tested an area 70 metres south of C19-08 intersecting 58.50 metres
of 1.93 gpt Au (32.00 metres true width), including 13.55 metres of
4.58 gpt Au, and including 4.55 metres of 10.26 gpt Au Figure 2).
Hole C19-21 was collared 30 metres south of C19-17 and intersected
62.25 metres (33.00 metres true width) of 1.47 gpt Au, including
19.25 metres of 2.20 gpt Au, and including 6.75 metres of 2.80 gpt
Au (Figure 3), and hole C19-22, located 55 metres south of C19-21,
intersected 32.75 metres (18.00 metres true width) of 1.24 gpt Au,
including 4.25 metres of 3.07 gpt Au. Collectively, the four holes
define a broad panel of mineralization at depth in the sill,
approximately 150 metres wide that spans from 190 metres to 470
metres vertical depth where it remains open.
Holes C19-10 and 10B were laid out
to explore the zone north of its higher-grade core and to determine
if significant mineralization exists above the presumed plunge of
its central hub (Figure 1). Although both holes intersected
mineralization, and in the case of the steeper hole
C19-10B which intersected an
extensive area of lower-grade material (46.25 metres of 0.67 gpt
Au, including 23.25 metres of 1.04 gpt Au), the holes did not
intersect grade typical of the zone's higher-grade core.
Holes C19-14 and C19-30 were drilled on the same section located
60 metres southwest of C19-10 to explore the northern edge of the
plunging zone to depth. C19-14, the shallower of the two holes did
not encounter mineralization typical of the zone's higher-grade
core, while the steeper hole C19-30 intersected a broad area of
mineralization centred at 450 metres vertical depth that returned
9.00 metres of 2.12 gpt Au, including 4.50 metres of 3.72 gpt Au,
followed by a deeper section of 7.50 metres of 2.22 gpt Au,
including 3.0 metres of 3.81 gpt Au.
Holes C19-11 and 11B were collared
265 metres northeast of the C19-10 series holes in an area the
Company had never previously drilled but where historical drilling
indicated the presence of the mineralized sill (Figure 1). Both
holes intersected narrow areas of weakly mineralized quartz diorite
to a vertical depth of 140 metres, but presumably well above the
zone's steeply plunging higher-grade core.
Since its discovery in 2014 Zone 1.5 has been drilled to 300
metres in strike, to a vertical depth of 660 metres, and a true
width of 30 to 60 metres in the near surface, but upwards of 155
metres at depth. 2019 drilling is looking at refining these
dimensions, particularly to depth where it is largely open. Updated
zone dimensions will be determined once the results from the
remainder of the 2019 drilling is available.
Treasure
Island
Treasure Island lies 11 km
north of Colomac along the eastern end of the Treasure Island – Laurie Lake Mineralized
Corridor, a 7 km long underexplored pathway that hosts several
high-priority gold showings. Mineralization is hosted by a series
of sub-vertical stacked gold zones that coincide with a regional
east-west mafic volcanic and sedimentary rock contact (Figure 4).
Drilling has defined the system as being upwards of 200 metres wide
and 700 metres long, where it remains largely open along strike and
to depth.
The Company's 2011 drill program was comprised of 5 drillholes
(1,452 metres) that targeted the historical Main Zone located
along the southwest shore of the island. Drilling was highlighted
by a 215-metre intersection of 0.74 gpt Au, including 4.0 metres of
14.43 gpt Au; showcasing the zone's extremely broad mineralized
envelope and its capacity to host internal domains of much
higher-grade. This maiden drill program successfully delivered on
the primary objectives of verifying historical reports of gold
in association with the contact, extending known mineralization in
all dimensions, and confirming the existence of new zones at depth
(see press release dated May 31,
2011). Surface exploration was carried out
intermittently between 2012 and 2018 and resulted in the discovery
of several new surface gold showings across the island further
establishing its emergent potential (see press release dated
April 12, 2018).
In 2018 Nighthawk completed its second drill campaign at
Treasure Island. A total of 16
holes for 4,035 metres were drilled within the Main Zone to trace
known mineralization to depth and along strike, and to test new
targets (see press release dated October 22,
2018). Broad areas of mineralization were intersected
throughout the contact zone between steeply dipping mafic volcanic
rocks to the north and greywacke units to the south intercalated
with intermediate to felsic pyroclastic volcanic rocks, highlighted
by 46.25 metres of 3.31 gpt Au, including 21.75 metres of 6.23 gpt
Au, and 7.75 metres of 14.20 gpt Au.
2018 was also the first time Nighthawk drilled the East Zone, a
second area of mineralization located 500 metres east of the Main
Zone. A new high-grade zone was intersected within a greywacke unit
100 metres from surface that returned 11.75 metres of 10.78 gpt Au,
including 6.50 metres of 19.15 gpt Au. This new discovery confirmed
the historical reports of East Zone mineralization, underscoring
the prospect's unexplored but strongly mineralized nature.
The Company's 2011 and 2018 drilling suggests that the
high-grade nature of the Main Zone may exist throughout the area's
700 metres of known mineralized stratigraphy, potentially linking
the two zones. The 2019 drill program is intended to follow up on
the previous programs by testing new areas between and along strike
of the zones, and to explore to greater depths by undercutting some
of the former intersections.
Holes T19-01 and T19-01B were
collared 25 metres west of previously drilled holes T18-01 and
T18-01B to extend the Main Zone
further west (Figure 4). Both holes intersected strong
mineralization with T19-01 returning 6.25 metres of 12.08 gpt Au,
including 2.50 metres of 28.61 gpt Au, while the steeper hole
(T19-01B) intersected the same zone
50 metres to 75 metres below, reporting an upper cut of 27.25
metres of 1.41 gpt Au, including 9.25 metres of 2.37 gpt Au, and
including 3.50 metres of 4.21 gpt Au, followed by a deeper
intersect of 6.50 metres of 10.20 gpt Au, including 3.75 metres of
16.38 gpt Au (Figure 5). This represents the farthest west the Main
Zone has been drilled to-date and has now been traced from surface
to 200 metres vertical depth where it remains open.
Treasure Island is one of
Nighthawk's premier regional assets and remains largely untested,
as does the 4 kilometres that separates Treasure Island from Laurie Lake to the west, leaving more than 90%
of this mineralized corridor to be explored.

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.
