Colomac Highlight: Hole C20-07 returned 3.00 g/t Au over 32.7 m

Treasure Island Highlight: T20-09 returned 207.18 g/t Au over 5.5 m (uncut), including 2,260 g/t Au over 0.5 m TORONTO, ON / ACCESSWIRE / April 5, 2021 / Nighthawk Gold Corp. ("Nighthawk" or the "Company") (TSX:NHK)(OTCQX:MIMZF) is pleased to report the remaining results from its 2020 exploration program on the Colomac Deposit ("Colomac") and the Treasure Island Zone ("Treasure Island"), within its 100% owned Indin Lake Gold Property (930km2 land package), located in the Northwest Territories of Canada.

Assay results from the remaining drill holes completed at Colomac (10 holes for 6,433 metres, see Table 1, Figure 1), and Treasure Island (3 holes for 1,186 metres, see Table 2, Figure 7), have been received and returned significant results at both locations.

Richard Roy, VP Exploration commented: "We are pleased to report on the remaining 2020 drill results at Colomac and Treasure Island. Treasure Island encountered high-grade results, where hole T20-09 returned 207.18 g/t Au over 5.5 metres, including a single assay of 2,260 g/t Au over 0.5 metres. Consistent higher grade at Treasure Island remains to be demonstrated by drilling. With these recent Treasure Island results now in hand, all results to date will be compiled, analysed, and modeled in order to establish its potential to add higher-grade mineralization to the global resource base.

"The Colomac results illustrate the potential for resource growth at depth, however drilling in 2021 will focus on further delineation of near-surface mineralization in an effort to increase the in-pit resources. The potential at depth on Colomac remains very significant, but quality near surface targets remain untested at Colomac and will be prioritized in 2021."

Colomac:

• Hole C20-07C (Figure 2) was completed at Zone 3.5 and returned 3.00 grams per tonne gold ("g/t", "Au") over 32.7 metres ("m"), supporting the continuity of the higher-grade mineralization previously obtained at depth.

• Holes C20-14 and C20-17(17B) tested Zone 2.5 at depth. Although no extensively wide intervals were obtained, hole C20-17 (Figure 3), did return a high-grade interval of 12.36 g/t Au over 4.3 m (26.08 g/t Au uncut) including a 0.5 m sample assaying 218.00 g/t Au.

• Holes C20-15(15B), C20-16, C20-18(18B), and C20-20 were drilled on Zone 1.5 testing the depth extension of the mineralization. Significant intervals were obtained, particularly in holes C20-18B (Figure 4), which returned 1.67 g/t Au Au over 61 m (1.72 g/t Au uncut), and C20-20 returned 2.44 g/t Au over 30.25 m (Figure 5). These results demonstrate that Zone 1.5 remains wide and well mineralized at depth, adding to the resource potential within this zone.

• Holes C20-19 (Figure 6), tested Zone 2.0 and returned a wide intersection of 1.03 g/t Au over 64.1 m, including 2.88 g/t Au over 7.5 m at. Drilling at Zone 2.0 continues to encounter both extensive widths and higher-grade intervals within the mineralization.

Treasure Island:

• The remaining three holes completed at Treasure Island (Main Zone), returned significant higher grade gold mineralization at depth, including:

  • Hole T20-07 (Figure 8) returned 5.62 g/t Au over 3.3 m;

  • Hole T20-09 (Figure 9) returned 4.65 g/t Au over 2.05 m, and 207.18 g/t Au over 5.5 m (uncut), including a single assay result of 2,260.00 g/t Au over 0.5 m; and

  • Hole T20-10 (Figure 10) returned 37.59 g/t Au over 2.35 m (uncut) including a single sample of 0.5 m which assayed 80.75 g/t Au.

Note: Assay results for Colomac are cut at 50 g/t Au as per parameters identified within the 2021 Mineral Resource Estimate. No cutting is applied to Treasure Island holes. Lengths are reported as core lengths. True widths vary depending on drill hole dip.

Qualified Person

Richard Roy P.Geo., a member of OGQ and NAPEG, V.P. Exploration of Nighthawk, who is the Qualified Person as defined by NI 43-101 for this project, has reviewed and approved of the technical disclosure contained in this news release.

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 Chemex Assay Laboratory in Vancouver, BC ("ALS Chemex"). ALS Chemex is an ISO 9001:2000 certified 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 Chemex.

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 underexplored Archean gold camp, the Company has identified a number of high-priority targets all centered around a growing multi-million-ounce deposit. These targets lie within large regional deformation zones that are pregnant with gold mineralization and are known to host significant deposits which warrant additional exploration and follow-up. The main goals and objectives over the next 12-24 months will be to carry out aggressive exploration to support resource expansion opportunities as well as to foster new, near-surface discoveries that support the global 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 complete its goals and objectives.
