Nighthawk Provides a Review of its Indin Lake Exploration Activities and Outlook for 2019

TORONTO, March 4, 2019 - Nighthawk Gold Corp. ("Nighthawk" or the "Company") (TSX: NHK; OTCQX: MIMZF) is pleased to provide a summary of exploration work completed to date within its Indin Lake Gold Property, including its flagship Colomac Gold Project ("Colomac"), and provide an outlook for 2019 milestones.

Dr. Michael Byron, President and CEO commented, "The consolidation of the Indin Lake Gold Property and the acquisition of Colomac, were the two key milestones that enabled us to deliver on the vast potential of this undeveloped camp. We are fortunate to have had the resources necessary to continue the process that we started in 2009 into 2019. Each year of activity has delivered new and exciting successes that we have built upon.

"We've advanced Colomac from a small little-known former producer, to a multi-million-ounce deposit with a new high-grade storyline, with the potential to deliver much more. We firmly believe that as Colomac grows so will the credibility of the gold camp that it resides in, and we are strategically positioned to reap the benefits. 2019 will again see us expand on all exploration fronts, committed to delivering on our vision for developing Canada's next gold camp."

NIGHTHAWK VALUE PROPOSITION:

• Tier 1 Jurisdiction – Progressive Northwest Territorial government committed to infrastructure development to support the resource industry, alongside invested and pro-mining First Nations governments. The Fraser Institute ranked the Northwest Territories #10 in the world for most attractive jurisdictions for mining investment, up from #21 in 2017.
  
  
• District Scale Land Position – Consolidation of a vastly underexplored Archean gold camp with numerous deposits and showings, centred around a growing multi-million-ounce gold project.
  
  
• 2.6 Million Ounces and Growing – Colomac is a large mineralized system, with current inferred resources of 50.31 Mt at an average grade of 1.62 grams per tonne gold ("gpt", "Au"). Approximately 50% of the sill has been explored to date leaving room for additional resource expansion opportunities.
  
  
• Important High-grade Discovery at Zone 1.5 – With the discovery of distinct high-grade domains at Colomac, the Company has effectively changed the dynamics of the deposit as it could lead to more favourable economics and allow exploitation deeper into the system. The exploration and delineation of additional high-grade zones remains an important focus going forward.
  
  
• Regional Targets Provide Upside for the Camp – There are at least seven priority satellite prospects that have the potential to provide high-grade feed opportunities to augment any future production scenario at Colomac. While these near-surface targets require more drilling, they are prime examples of the robust nature of the camp, as most host good grades and widths.
  
  
• Proven Leadership – Dr. Michael Byron is a founding member of Aurora Platinum (acquired by FNX Mining Company Inc.), Lakeshore Gold Corp (acquired by Tahoe Resources), and Falco Resources. The senior management team and Board of Directors offer a diversity of experience within the industry over a collective 30-year span.
  
  
• Fully Funded – Company has a strong cash balance of $16.4 million (as at September 30, 2018), and is funded to complete its goals and objectives for the next 12 months.
  
  
• Supportive Shareholders and Strategic Partnerships – The Company is supported by a shareholder base that have experienced success in previous supportive placements such as FNX Mining Company Inc., Gold Eagle Mines Ltd., and Queenston Resources Inc. Our long-term shareholders including Robert Cudney and Northfield Capital Corporation have continuously supported the Company and are committed to helping Nighthawk achieve its stated goals and objectives. As well, the strategic partners, Kinross Gold Corp. and Osisko Gold Royalties Ltd., have provided tremendous support.

2019 and Beyond

Nighthawk has received its land use permits and water licences approving its exploration activities over the next 5 years, expiring in February 2024, and which are extendible up to February 2026. The permits cover all claims and mining leases within the Company's 100% owned Indin Lake Gold Property. Exploration activities are expected to commence mid-March, with a minimum 25,000 metre drill program split relatively evenly between Colomac and its high-level regional targets. 

Nighthawk's goals and objectives moving forward include:

Colomac

• Target of +3Mozs of resources with the completion of the 2019 drill program
• Domaining of high-grade zones for subsequent resource estimates and elevating them to the indicated resource category
• Metallurgical test-work on additional areas within the sill to assess potential variabilities and overall expected recoveries as well as generate a sound statistical framework for the heap leach opportunity
• Complete an internal scoping study to assist with future exploration activities, and provide the base work for any future PEA

Regional Targets

• Maiden resource estimate for the Damoti Lake Gold Deposit
• Drill high-priority regional targets to advance them up the value chain
• Continue regional exploration and prospecting work to identify new targets and prioritize existing targets to drill-ready status

Summary of Exploration Activities to Date

Colomac

In addition to 85,178 metres of historical drilling, the Company drilled a total of 56,216 metres between 2012 and 2017 resulting in the June 2018, NI 43-101 updated resource estimate outlining 50.31 million tonnes at an average grade of 1.62 gpt Au for a total of 2.6 million ounces of inferred resources (see press release dated June 13, 2018).

Growth Opportunities and Upside Potential (see website Colomac)

• Colomac is a large mineralized system and given that Nighthawk's drilling success rate is greater than 97%, the opportunity to continue to grow resources with additional drilling is considered exceptional.
• The Company believes that with every 30,000 to 40,000 metres of drilling, a meaningful resource update can be achieved.
• With the discovery of high-grade Zone 1.5, and additional potential high-grade zones within the sill, the prospects to explore deeper within the system exists, which should positively impact project economics going forward (see press releases dated December 3, 2014, October 16, 2016, August 24, 2017, November 28, 2017, and September 11, 2018).
• Excellent metallurgical recoveries of between 96.5% up to 98.0% using conventional recovery methods. As well, initial heap leach testing returned encouraging results (up to 81.8%), however additional testing is required to get a more representative set of sample results (see press releases dated April 19, 2017 and May 22, 2018).

District-scale Land Position with Numerous Gold Deposits and Showings

Within the extensive Indin Lake Gold Property (899 km²), Nighthawk has identified several high-grade showings and deposits with widespread mineralization in a range of styles that are largely hosted in brittle regimes, typomorphic of many productive high-profile Archean gold camps. The continued exploration success from the satellite targets supports Nighthawk's conviction that the Colomac deposit is not the only multi-million-ounce opportunity capable of hosting high-grade mineralization. The many prospective regional targets provide a remarkable opportunity for growth and collectively strengthen the Company's 100% controlled regional play centered on Colomac, a growing, multi-million-ounce gold deposit.

The following table summarizes some of the more prospective regional targets and showings within the Indin Lake Gold Property, including the work completed to date by Nighthawk. Most are at an early exploration stage and require additional work to realize their ultimate potential. For more information on the Company's regional targets, please visit the Regional Exploration section of the website.

For detailed overview of recent field work on these targets, see press release dated February 19, 2019.

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.
