TORONTO, July 5, 2018 /CNW/ - Nighthawk Gold Corp. ("Nighthawk" or the "Company") (TSX: NHK) (OTCQX: MIMZF) is pleased to announce drill results from the Leta Arm Project ("Leta Arm"). Twenty-two holes (5,169 metres) were recently completed at the Diversified deposit, as well as the Number 3, and Lexindin showings, highlighted by a new discovery at Diversified where hole DV18-08 intersected 17.50 metres of 5.81 grams per tonne ("gpt") gold ("Au"), including 9.25 metres of 9.65 gpt Au, and 4.75 metres of 18.12 gpt Au. DRILLING HIGHLIGHTS:

• Hole DV18-08 intersected 17.50 metres (14.00 metre true width) of 5.81 gpt Au, including 9.25 metres of 9.65 gpt Au, and 4.75 metres of 18.12 gpt Au;

• Hole DV18-08B intersected 7.75 metres (5.00 metre true width) of 3.66 gpt Au, including 5.50 metres of 5.05 gpt Au, and 2.50 metres of 10.65 gpt Au;

• Hole DV18-06 intersected 14.10 metres (7.00 metre true width) of 3.50 gpt Au, including 6.65 metres of 6.67 gpt Au, and 2.35 metres of 18.50 gpt Au;

• Hole DV18-07 intersected 11.75 metres (9.50 metre true width) of 3.86 gpt Au, including 8.00 metres of 5.34 gpt Au, and 4.25 metres of 8.07 gpt Au;

• Hole DV18-07B intersected 10.00 metres (5.00 metre true width) of 3.10 gpt Au, including 6.25 metres of 4.90 gpt Au, and 3.00 metres of 9.12 gpt Au;

• New gold zones discovered at Diversified and Lexindin;

• Drilling has validated the northerly steep plunging mineralization model as being a common feature to the four Leta Arm prospects.

Note: All assays are uncut (see Table 1) Dr. Michael Byron, President and CEO commented, "Given our positive exploration results to-date, we are confident that the four Leta Arm gold deposits and showings are part of the same mineralized system as they share similar styles of mineralization, mineralized widths, general morphology, a common steep northern plunge, and are distributed along a linear array. We intend to continue advancing our understanding on the mineralization controls in this high-profile region and will broaden our exploration efforts along the 10 kilometres of mineralized stratigraphy in search of new discoveries. Leta Arm is just one of the many projects that we are aggressively exploring in 2018 and features prominently in our objective of realizing the untapped potential of this fertile gold camp." Leta Arm lies sixteen kilometres southwest of Nighthawk's Colomac Gold Project ("Colomac"), Northwest Territories, Canada (Figure 1) and straddles the Leta Arm Fault Zone ("LAFZ"), a north-south trending, well mineralized, regional deformation zone up to 10 kilometres long and 500 metres wide that hosts all four of the deposits and numerous gold showings. The four Leta Arm prospects were discovered in the late 1940's and early 1950's and are characterized by numerous high-grade vein systems developed within a 2.8-kilometre portion of the Leta Arm Fault Zone. Deposits and showings lie within a highly altered shear zone up to 500 metres wide hosting both parallel and extension vein systems open in all dimensions. A total of fourteen holes were drilled at Diversified (3,446 metres), six at Number 3 (1,294 metres), and two at Lexindin (429 metres), as presented in Table 1 below. Results for the North Inca deposit were presented in the Company's June 26, 2018 press release.
