Nighthawk Drilling at Goldcrest Intercepts 15.50 Metres of 5.47 Gpt Au (uncut) Including 4.25 Metres of 16.98 Gpt Au
Feb 19, 2020, 07:01 ET
TORONTO, Feb. 19, 2020 /PRNewswire/ - Nighthawk Gold Corp. ("Nighthawk" or the "Company") (TSX: NHK;OTCQX: MIMZF) is pleased to report drill results from the Goldcrest sill ("Goldcrest"), a parallel sill located 400 metres east of the Colomac Main sill ("Colomac Main"), and part of the Company's flagship Colomac Gold Project ("Colomac"), located within the north-central portion of its 100% owned Indin Lake Gold Property Northwest Territories, Canada (Table 1, Figure 1). Seven holes (2,190 metres) were drilled to follow-up on areas highlighted by Nighthawk's three previous drill campaigns, and to target new resource expansion opportunities within Goldcrest's southern section ("Goldcrest South").
Dr. Michael Byron, President and Chief Executive Officer said, "Goldcrest is very similar to Colomac Main except it has been drilled significantly less and has a shorter strike length of 2.5 kilometres compared to the 9-kilometre strike length of Colomac Main. Goldcrest was last drilled in 2017 and several key areas remain unexplored as illustrated by the high-grade intercept in hole C19-05. This hole was drilled within a previously untested section of the sill tracing strong continuity of mineralization to depth. We continue to encounter robust mineralization throughout the Colomac area sills, which reinforces our belief that with continued exploration, new discoveries and ongoing expansion of known zones will follow."
All holes intersected gold mineralization over a strike length of 400 metres within Goldcrest South (Figure 1). Most of the holes were drilled steeply in order to explore the sill below previous drilling and encountered new mineralization intersected over significant downhole lengths. Values typical of Colomac Main-type high-grade zones were encountered in hole C19-05 with the latest holes extending mineralization to new depths. Large portions of the sill remain unexplored to depth as well as along strike to the south, within the northern portion of Goldcrest ("Goldcrest North"), and within the 800-metre section that separates Goldcrest South and Goldcrest North (Figure 1).
Goldcrest Drilling Highlights:
- Hole G19-05 intersected 68.50 metres (8.00 metre true width) of 2.00 gpt Au, including 15.50 metres of 5.47 gpt Au, and including 4.25 metres of 16.98 gpt Au (Figure 2). Two additional downhole intercepts returned 15.25 metres (2.00 metre true width) of 1.77 gpt Au including 4.00 metres of 5.31 gpt Au, and 16.25 metres of 1.46 gpt Au including 1.5 metres of 9.25 gpt Au.
- Subvertical hole G19-05 was drilled down the sill in an open area between two previous Nighthawk holes and intersected 130 metres of relatively continuous downhole mineralization throughout a 20.00 metre true width to a vertical depth of 153 metres where it remains open.
- Subvertical hole G19-05 was drilled down the sill in an open area between two previous Nighthawk holes and intersected 130 metres of relatively continuous downhole mineralization throughout a 20.00 metre true width to a vertical depth of 153 metres where it remains open.
- Hole G19-02 returned several intersects of continuous mineralization highlighted by a deep intercept of 7.75 metres (2.00 metre true width) of 6.95 gpt Au, including 3.25 metres of 15.83 gpt Au at a 425-metre vertical depth (Figure 3).
- Hole G19-02 is the deepest hole ever drilled at Goldcrest. It was intended to explore the sill's depth potential and intersected nine separate stacked mineralized lenses distributed among alternating horizontal bands of quartz gabbro and quartz diorite over its 501-metre downhole length. This type of layering has not been documented elsewhere within the sill.

It was intended to explore the sill's depth potential and intersected nine separate stacked mineralized lenses distributed among alternating horizontal bands of quartz gabbro and quartz diorite over its 501-metre downhole length. This type of layering has not been documented elsewhere within the sill.
- The current holes have infilled gaps in drill coverage within the main body of the sill and explored new areas to depth with all holes intersecting mineralization.
- Goldcrest has been drilled significantly less than Colomac Main, thus the potential for new discoveries remains high. Ongoing success in locating and expanding new higher-grade zones within Goldcrest offers strong support for resource expansion opportunities going forward.

Goldcrest is a 2.5-kilometre-long mineralized differentiated igneous intrusion that lies parallel to Colomac Main located 400 metres to the east. The sills are believed to be co-magmatic and have intruded a package of dominantly mafic volcanic rocks that were subsequently folded upright such that stratigraphic tops are now facing east. Gold mineralization is largely restricted within the more silica-rich upper portions of the sills, an area that is a primary exploration focus for the Company. The Goldcrest deposit is currently composed of two main regions of mineralization: Goldcrest South and Goldcrest North (Figure 1). The much smaller Goldcrest North is located 800 metres northwest of Goldcrest South and may possibly represent a detached portion of the sill. The area separating the two regions has never been drilled.
The Company has now completed four drill programs at Goldcrest (see press releases dated September 25, 2014; November 26, 2014; October 12, 2016; November 24, 2016; December 21, 2016; and December 13, 2017), yet it remains largely underexplored along strike and to depth.
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.
About Nighthawk
Nighthawk is a Canadian-based gold exploration company with 100% ownership of a district-scale land position within the Indin Lake Greenstone Belt, located approximately 200 km north of Yellowknife, Northwest Territories, Canada. Nighthawk is focused on advancing the Colomac Gold Project with a current inferred resource of 2.6 million ounces of gold (50.3 million tonnes at an average grade of 1.62 grams per tonne gold), as well as advancing its other regional gold deposits and showings within this largely underexplored Archean gold camp.
The Company has an experienced and dedicated team and is well funded to complete its goals and objectives over the next 12 months.

Although Nighthawk has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information. Accordingly, readers should not place undue reliance on forward-looking information. Nighthawk does not undertake to update any forward-looking information, except in accordance with applicable securities laws.
