Nighthawk Announces 2018 Drilling Program Of A Minimum Of 25,000 Metres And Expands Targeting Program Within Its Indin Lake Gold Property
Toronto, Ontario, March 21, 2018 – Nighthawk Gold Corp. (“Nighthawk” or the “Company”) (TSX: NHK; OTCQX: MIMZF) is pleased to announce the initiation of its 2018 drill campaign consisting of a 25,000-metre diamond drill program on its 100% owned Indin Lake Gold Property in the Northwest Territories, Canada.
Three drill rigs will be in operation from early March until late September focussed on the continued exploration for high-grade gold zones within the Colomac Gold Project (“Colomac”), the ongoing delineation of known high-grade gold zones such as Zone 1.5, and drilling of select priority gold targets within its vast regional land package (Figure 1). Extensive geological mapping, prospecting, and ground geophysical programs will begin by mid-June, directed at better defining known targets and generating new opportunities, with the goal of advancing Nighthawk’s many regional showings and deposits to a drill ready status.
- Drilling will continue to expand Colomac Zones 1.0, 1.5, 2.5, 3.5, Goldcrest, and Grizzly Bear (Figure 1) along strike and to depth, and to explore for other potential zones of higher-grade mineralization within the sills.
- One drill will be active throughout the regional Indin Lake Gold Property for the entire 2018 program testing gold targets within the Leta Arm Gold Project (“Leta Arm”, which includes the North Inca and Diversified Mines, the #3 and Lexindin showings), the Damoti Lake gold deposit, Treasure Island showing, and other top prospects.
- Drilling has commenced at Leta Arm to test North Inca and Diversified from lake setups to follow up on the Company’s 2011 drill results as well as test the down plunge and strike extensions of the vein systems.
- Drilling is planned for the Company’s high-grade Damoti Lake gold deposit (“Damoti”). A 2005 resource estimate* pursuant to National Instrument 43-101, reports a measured and indicated resource, at a cut-off grade of 8.00 grams per tonne gold (“gpt”, “Au”), of 40,600 tonnes grading 26.17 gpt Au, and an inferred mineral resources of 17,800 tonnes grading 16.38 gpt Au (see press release dated, November 17, 2005, for Anaconda Gold Corp.). The Company believes there is opportunity to grow this resource beyond it’s current high-grade core.
- Damoti is central to the logic for consolidating the Indin Lake Gold Camp, as it represents a very high-grade satellite deposit that could augment any future Colomac gold production. It also shows the prospective grade and contained gold ounces that regional assets may contain, and their potential to strengthen Nighthawk’s 100% controlled district play centered on Colomac, a mutli-million-ounce deposit with significant growth possibilities.
- 2018 will see the continuation of focused mapping and prospecting programs directed at advancing Nighthawk’s many regional showings and deposits in preparation for drilling, and to generate new opportunities through escalated exploration activities.
- The main objectives of the 2018 program are to better define and expand on the dimensions of higher-grade mineralization intersected to-date, to explore for other new zones of near surface higher-grade material, to become more aggressive with regional exploration and drilling activities, and to advance the Company’s many priority deposits and showings that are key to the evolution of this early gold camp and potential mining activities at Colomac.
*Note: The reader is cautioned that a qualified person has not done sufficient work to classify the historical estimates presented in this news release as current resources. The Company has not verified these historical resources and is not treating these historical estimates as current mineral resources. While these estimates were prepared in accordance with National Instrument 43-101, there is no assurance that they are in accordance with current standards and these resource estimates should not be regarded as consistent with current standards or unduly relied upon as such. Nighthawk includes these historical estimates for information purposes as they represent material historical data which have previously been publicly disclosed. (In 2005, a report titled “Technical Report and Resource Estimate on the Damoti Lake Property, Northwest Territories, Canada” was prepared for Anaconda Gold Corp. by P & E Mining Consultants Inc. and authors Eugene Puritch P.Eng, and Wayne D. Ewert P.Geo (see Anaconda’s profile at www.sedar.com for a copy of this historic report)). To Nighthawk’s knowledge, the 2005 Technical Report is the most recent resource estimate available regarding the Damoti Lake deposit.
Dr. Michael Byron, President & CEO commented, “Our 2018 exploration season will be more aggressive than our 2017 season, which was our most active and extensive to-date. With a cash balance of $26 million, our planned budget of approximately $11 million will allow us to expand our exploration activities outside of Colomac to advance some of our most prospective Indin Lake area deposits and prospects as we continue to develop our core theme of an evolving gold camp centred on Colomac’s exceptional multi-million-ounce growth potential. Our Damoti Lake deposit is key to this thesis, being an example of the incredible high-grade gold mineralization over sizable widths that we feel is indicative of the untapped opportunities this gold camp has to offer. We are confident that our evolving understanding of the camp will fuel many additional new discoveries, that like Damoti, will play a significant role in the economical viability of a future Colomac mining operation”.
2018 Regional Drill Targets
Damoti Lake Gold Deposit
The Damoti Lake gold deposit lies 28 kilometres (“km”) south of Colomac. Mineralization is hosted in folded iron-formation associated with fold related fracturing and hydrothermal alteration where gold is preferentially located within fold noses and parasitic structures. A small historical, but high-grade, near-surface deposit was previously defined showing excellent expansion potential (see press release dated, November 17, 2005, for Anaconda Gold Corp.). An independent, National Instrument 43-101 compliant resource estimate was completed in September 2005 for Anaconda Gold Corp. (Refer to report “Technical Report and Resource Estimate on the Damoti Lake Property, Northwest Territories, Canada”, dated December 22, 2005, available under Anaconda’s profile at www.sedar.com), who at the time were considering a mining operation that targeted the highest-grade portion of the deposit. Using a cut-off grade of 8.00 gpt Au, the measured and indicated mineral resource estimate for the deposit totaled 40,600 tonnes grading 26.17 gpt Au, with a further inferred mineral resource estimate of 17,800 tonnes grading 16.38 gpt Au. Resources completed prior to the implementation of NI 43-101 are referenced in the technical report and suggest the potential for a larger lower grade deposit. Damoti was also the subject of a 1996 underground exploration program via a shallow ramp into the heart of the high-grade resource.
In 2009 and 2010 Nighthawk drilled a total of 13,647 metres to explore for new zones throughout the property (Table 1). Damoti is important to the consolidation of the Indin Lake Gold Camp, as it represents a very high-grade satellite deposit that could augment any future Colomac gold production. It also reveals an opportunity that regional assets may represent in terms of grade and contained gold ounces to strengthen Nighthawk’s 100% controlled regional play centered on Colomac, a mutli-million-ounce deposit with significant growth possibilities.
Numerous drill ready targets exist on the property that the Company will be testing later in the 2018 program.

Leta Arm Gold Project
Leta Arm lies 15 km southwest of Colomac, along the Leta Arm Fault Zone (“LAFZ”), a broad feature parallel to the northern extension of the West Bay - Indin Lake Fault Zone; a major regional structure hosting the former producing Giant and Con gold mines to the south (13 million ounces of historic gold production).
Leta Arm is comprised of two historical gold mines (North Inca and Diversified) and two high-profile gold showings (#3, and Lexindin), and populates a 2.5-km section of this 10-km-long, 500-metre wide north-south trending regional deformation zone. The Diversified Mine lies 1.3 kilometres north of the North Inca Mine, with the #3 showing located between them, and the Lexindin showing an additional 1.2 km north of the Diversified shaft. All deposits are open laterally and vertically suggesting the possibility that they may be part of a single larger system. Exploration shafts and limited underground development were completed on the North Inca and Diversified deposits in the 1940’s to explore multi-stage quartz veins characterized by high-grade gold mineralization.
In 2011 Nighthawk drilled 10,536 metres on the Leta Arm prospects (see press release dated January 17, 2018), testing a 2.4-km section of the LAFZ that resulted in the discovery of new zones and the extension of historical zones along strike and to depth. Results exceeded expectations confirming the project’s exciting near-surface discovery opportunities and potential for delivering significant mineralized widths. Drilling in 2018 will focus on extending the deposits and exploring for a potential connection along strike, while actively searching for new deposits along the LAFZ. The Leta Arm remains a key area of interest for the Company. The abundance of its near-surface deposits and expansive mineralization, their underexplored status yet impressive mineralized widths, and proximity to Colomac, make them valuable assets as potential feed to augment possible future production at Colomac.
North Inca Mine
North Inca consists of at least 3 parallel north striking silicified zones of variable widths. Historical development was limited to vertical depths of less than 100 metres, leaving the deposit open to exploration at depth. The en-echelon nature of the quartz vein sets indicates a potential for the deposit to continue along strike. Initial Nighthawk drilling in 2011 tested the East Zone, the eastern most mineralized zone within host metasedimentary units, and near surface mineralization within metavolcanic rocks located 150 metres west (West Zone) of the East Zone. The program was successful in confirming its high-grade nature, the discovery of new zones, extending known zones laterally and to depth, and defining zone widths much broader than previously recognized.
Four holes were drilled at North Inca near the end of the 2017 campaign. Two of the holes undercut East Zone mineralization reported in 2011 drilling, in which hole NI17-01 (see press release dated January 17, 2018) drilled a gap between NI11-02 series holes and NI11-03, intersecting 13.20 metres of 2.24 gpt Au, including 8.50 metres of 3.24 gpt Au, and extending mineralization over 70 additional metres to depth where the zone remains open. The two other holes, NI17-02 and NI17-02B, drilled a West Zone section across three subvertical vein systems and infilled a gap between the NI11-04 and NI11-05 series holes. Both holes intersected mineralization with NI17-02 returning 9.55 metres of 4.03 gpt Au, including 3.00 metres of 8.14 gpt Au.
The Diversified deposit is similar to North Inca. The deposit's intensely silicified "Main Zone" lies within metasedimentary rocks and has been traced for 220 metres based on historical drilling and underground development. Nighthawk’s 2011 drilling confirmed the high-grade nature of the deposit's mineralization, defined zone widths that significantly exceed those previously reported, and extended the high-grade mineralization to new depths. All mineralized zones remain open laterally and to depth.
#3 Gold Showing
The #3 gold showing lies along the LAFZ 450 metres south of the Diversified shaft and 800 metres north of the North Inca East Zone. Nighthawk believes the three metasediment-hosted gold deposits are part of the same mineralized structure as they have similar gold grades, mineralized widths, and general morphology, and when viewed in longitudinal section, share the same orientation.
Lexindin Gold Showing
Located 1.5 km north of Diversified, the Lexindin showing consists of tensional en-echelon quartz veins oblique to branches of the main shear zone. In 2011 Nighthawk prospected a 250-metre-long shear zone along the west shore of the LAFZ across from the showing. Surface grab samples assaying up to 8.81 gpt Au were taken from quartz-carbonate veins suggesting that mineralization in this area may be wider spread than previously believed (see press release dated September 12, 2011).
Treasure Island Gold Showing
Treasure Island is located 11 km north of Colomac within a 6 km mineralized corridor that hosts several gold showings. The area between its Main Zone and East Zone (located 600 metres to the east) remains untested, as does the 4 km that separates Treasure Island from the Laurie Lake gold showing to the west, thus more than 75% of this mineralized corridor is yet to be explored.
In 2011 Nighthawk drilled five holes into the Main Zone targeting a series of stacked gold zones associated with a 200 metre wide envelope of silicification along the volcanic rock-sedimentary rock contact (Table 2). The Company realized its primary objectives of confirming historically reported gold along this contact region, testing for new zones at depth, and extending zones in all dimensions. Reported broad zones of mineralization with internal higher-grade intersects appear to be continuous for over 150 metres along strike (open) and down dip (open). New high-grade gold zones were also discovered at depth within altered metasedimentary rocks, and near surface within metavolcanic rocks.
Ground geophysical surveys (Induced Polarization and Magnetometer) will be completed this winter in preparation for exploration drilling later in the 2018 campaign.

Within its 899 km2 land package Nighthawk has many other highly prospective and untested prospects in the pipeline that have been steadily advanced towards a drill ready state. Several of these (Echo-Indin, JPK, Swamp, Andy Lake, Nice Lake) are candidates to be tested in 2018, as the Company continues to aggressively build on its regional gold camp strategy of discovering and evolving near surface gold deposits to augment the ever growing Colomac Gold Project.
