Nighthawk Reports Drill Results from its Phase I 2021 Exploration Program at Colomac and Goldcrest
TSX: NHK
Wide, near surface mineralization identified at Colomac, and high-grade mineralization encountered at the southern extension of Colomac/ Goldcrest.
Hole C21-05 returned 3.80 g/t Au over 22.40 m, including 6.37 g/t Au over 11.00 m
TORONTO, July 21, 2021 /CNW/ - Nighthawk Gold Corp. ("Nighthawk" or the "Company") (TSX: NHK) (OTCQX: MIMZF) is pleased to report assay results for twenty-three (23) drillholes (6,651 metres) at the main Colomac Deposit ("Colomac"), and four (4) holes (1,251 metres) at the Goldcrest within its Indin Lake Gold Property, Northwest Territories, Canada (Figure 1; Table 1).
Keyvan Salehi, President & CEO commented, ''We are quite pleased with the results at both the south and especially the north extension of Colomac, an area which has seen very limited drilling by the Company in the past. The main objective for these areas was to further expand the extent of mineralization along strike. The area to the north shows wide mineralization within 150 meters from surface showing better than expected continuity, albeit at slightly lower grades. However, given the shallow depth, lower grade mineralization can significantly enhance the total value of the project due to easier access and potentially lower strip ratios.
In the south area and at Goldcrest, the presence of narrower, high-grade intersections is very encouraging and ties into our efforts to increase the average grade of the global resource base. In both cases, further drilling will establish continuity of these intersections with an ultimate goal of delineating additional in-pit resources.''
Highlights of Colomac and Goldcrest Drilling:
- At the northern extension of Colomac (Zone 1.0), shallow isolated pit shells were included as part of the 2021 mineral resource estimate ("2021 MRE"), and drilling tested the potential for expansion given the limited amount of drilling to-date in this area (Table 1).
- C21-08 returned 1.10 grams per tonne gold ("g/t", "Au") over 33.50 metres ("m") (Figure 2);
- C21-13 returned 1.02 g/t Au over 25.45 m (Figure 3);
- C21-16 returned 1.05 g/t Au over 17.00 m (Figure 4); and
- C21-22 returned 1.35 g/t Au over 20.50 m (Figure 5).
- At the southern extension of Colomac (Zone 3.5), drilling followed up on previously encountered near-surface intervals in holes C20-05 and C20-05B and confirmed the presence of shallow high-grade mineralization (Table 2).
- C21-11 returned 4.70 g/t Au over 6.00 m, and 6.78 g/t Au (51.13 g/t uncut, over 4.25 m, including 427.00 g/t uncut over 0.50 m (Figure 6).
- Hole C21-05, which was collared from Colomac, was extended further to the west to undercut Goldcrest at depth and returned 3.80 g/t Au over 22.40 m, including 6.37 g/t Au over 11.00 m (Figure 6, Table 1).
To date, approximately 31,000 metres of drilling have been completed as part of the Phase I program, with 11,950 metres having been reported on. There is currently one (1) drill located at each of the following targets: the Cass Zone; the Albatross Target (immediately to the southwest of Cass); the Fishhook Target; the Laurie Lake Target; and at the 24/27 zones within the Colomac Centre.

Of the 23 holes at Colomac, 17 tested the north extension of the deposit where shallow isolated pit shells were included as part of the 2021 MRE. Given the limited drilling in this area, there remained potential for expansion at depth and along strike. Drilling focused on extending the shallow pits at depth and to explore open areas between the isolated pits along strike. Results encountered wide and continuous, near-surface mineralization in many holes both below the small pits as well as along strike. Although further drilling will be required in Phase II to better define these mineralized extensions, the current results suggest that the north pits may be larger than originally interpreted.

The remaining 6 holes drilled at Colomac tested the south extension of the deposit. In this area, previous drilling including Nighthawk's holes C20-05 and 05B (see press release dated September 29, 2020), returned narrow high grade near-surface intervals which deserved follow up. As shown in Table 2, hole C21-09 and C21-11 confirmed the presence of shallow high-grade mineralization which will be further delineated in Phase II of the program.
In addition, hole C21-05 was collared from Colomac Zone 3.5 but extended to the west to undercut the Goldcrest Zone at depth. The hole crossed a strongly mineralized zone returning 3.80 g/t Au over 22.40 metres, including 6.37 g/t Au over 11.00 metres. Very limited deep drilling has been completed to date at Goldcrest. Phase II will take advantage of other previous holes at Colomac by extending them further west and test the Goldcrest zone for high grade mineralization proximal to hole C21-05 intersection.
The four holes at Goldcrest to test the south extension of the zone, failed to return significant mineralization apart from a single assay of 14.20 g/t Au over 0.50 m starting at 162.00 metres in hole G21-03. No further work is contemplated for this area.

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 200km north of Yellowknife, Northwest Territories, Canada. Within this largely under explored Archean gold camp, the Company has identified a number of high-priority targets all centred around a growing deposit. These targets lie within large regional deformation zones that contain gold mineralization which warrant additional exploration and follow-up. The main goals and objectives over the next 6-12 months will be to carry out exploration to foster resource expansion opportunities as well as new, near-surface discoveries that support the global mineral resource base.
The Company has an experienced and dedicated team with a track record of successfully advancing projects and is well funded and supported to advance its near-term goals and objectives.
