Nighthawk Gold Corp. (TSX: NHK) provides additional drill results from its Treasure Island Gold Project, located 11 km north of the Company’s flagship Colomac Gold Project within the northern portion of its 100% owned Indin Lake Gold Property, Northwest Territories, Canada. Results are reported for eight holes (2,328 metres) recently completed at Treasure Island (Table 1, Figure 1). Drilling intersected broad zones of mineralization with internal higher-grade intervals, similar to previously reported intercepts and a positive sign for continued exploration success as Nighthawk looks to advance this target in the coming years. Assay results for the nine remaining holes (2,798 metres), completed at Treasure Island will be released once available.
Dr. Michael Byron, President and Chief Executive Officer said, “Treasure Island is one of several high-priority regional prospects that lie satellite to Colomac and given the underexplored status of the Indin Lake Gold Camp, we believe these prospects represent incredible opportunities for discovery and expansion. We consider regional prospects like Treasure Island that display excellent gold grades and mineralized widths as key components for strengthening any potential Colomac mining scenario.”
“We recently concluded our 2019 drill program on our Indin Lake Gold Property, completing 110 holes for 40,834 metres and significantly exceeding last year’s record of 32,500 metres, making it our most productive and efficient drill season to-date. We have now released results for 55 holes or 19,429 metres, leaving considerable news flow going forward. Over the past three years we have been fortunate to have the resources to aggressively expand our exploration activities and build on our regional gold camp strategy of discovering and evolving near-surface gold deposits within our emerging gold camp. Treasure Island is fundamental to this approach.”

Treasure Island is the northern most project within Nighthawk’s Indin Lake Gold Property near the eastern end of the Treasure Island – Laurie Lake Mineralized Corridor, a 7 km long underexplored tract host to several high-priority gold showings (Figure 1). Mineralization consists of several stacked zones located along a regional east-west volcanic rock/sedimentary rock contact. Drilling to-date defines a 200-metre-wide and 700-metre-long package of strongly altered and mineralized rock open along strike and to depth.
The Company has now completed its third drill campaign at Treasure Island. Its smaller 2011 maiden drill program successfully intersected and validated historical Main Zone mineralization along the southwest shore of the island (see press release dated May 31, 2011). In 2018 the company completed a larger follow-up program to trace known mineralization to depth and along strike, and to test new targets including its first drilling at the East Zone located 500 metres east of the Main Zone (see press release dated October 22, 2018). Broad areas of mineralization were intersected throughout the contact zone between steeply dipping mafic volcanic rocks to the north and greywacke units to the south.
Nighthawk’s 2019 drill program followed up on the previous programs by testing new areas between and along strike of the two zones and exploring to greater depths by undercutting previous intersections. Nineteen holes were drilled (5,816 metres) of which two holes have been previously released (see press release dated September 5, 2019). All eight holes reported today were drilled within the Main Zone.
Drillholes T19-02 and T19-02B explored a gap in drilling within the western section of the Main Zone, 25 metres east of previously drilled holes T18-02 and T18-02B (Figure 1), and 50 metres west of holes T18-03 and T18-03B. Both holes encountered extensive mineralization and extended stacked zones from 80 metres vertical depth to 130 metres on this section where the zone remains open. The shallower hole, T19-02, returned 6.50 metres of 10.08 gpt Au, including 4.00 metres of 15.94 gpt Au, with a deeper intersect of 22.40 metres assaying 1.27 gpt Au, including 6.00 metres of 3.04 gpt Au. The steeper hole, T19-02B, intersected 22.25 metres of 2.83 gpt Au, including 8.00 metres of 6.01 gpt Au (Figure 2).
Hole T19-03 was collared 50 metres east of T19-02 to undercut mineralization intersected by holes T18-03 and T18-03B. It extended mineralization on this section to 200 metres vertical depth where it remains open, intersecting an upper section that returned 6.00 metres of 1.99 gpt Au, including 3.75 metres of 2.53 gpt Au, with a deeper intersect of 20.50 metres assaying 1.27 gpt Au, including 9.25 metres of 1.74 gpt Au, and 4.25 metres of 2.29 gpt Au.
Hole T19-04 was drilled beneath the section drilled by holes T18-06 and 06B to trace the eastern part of the Main Zone to depth. It successfully tracked the zone to 200 metres depth where it remains open, intersecting 26.50 metres of 1.36 gpt Au, including 6.55 metres of 3.44 gpt Au (Figure 3).
Two other setups were established 50 metres and 100 metres east of T19-04 to explore the region separating the Main Zone and East Zone, an area that had never been drilled (Figure 1). Two holes were drilled from each setup. All holes intersected mineralization highlighted by T19-05B which returned 8.25 metres of 1.17 gpt Au, including 3.00 metres of 2.85 gpt Au; and T19-06B which returned 7.25 metres of 2.20 gpt Au, including 4.25 metres of 3.24 gpt Au, and 1.50 metres of 6.57 gpt Au.
Nighthawk’s drilling to-date has traced the Main Zone continuously for over 400 metres along strike, from surface to upwards of 200 metres vertical depth where it remains open. The Company has also begun to infill the region between the Main Zone and the East Zone to explore the linkage between the two zones and to determine if the high-grade nature of the Main Zone exists throughout the 700 metres of mineralized stratigraphy. Results from that drilling have not yet been received. Treasure Island represents a small part of the mineralized corridor’s 7 km strike length. The remaining portion of the corridor represents a priority for Nighthawk to be investigated in its 2020 exploration program.
Treasure Island – Laurie Lake Mineralized Corridor
Treasure Island was Nighthawk’s initial focus within this part of the Indin Lake Greenstone Belt; however, it was obvious that the regional geology was highly prospective being home to many historical and recently discovered gold showings including the Laurie Lake Showing and JPK. Laurie Lake lies near the western end of the Treasure Island – Laurie Lake Mineralized Corridor, 4 kilometres southwest of Treasure Island (Figure 1). Historical drilling references stacked mineralized zones with localized high-grade intercepts like those seen at Treasure Island, while historical surface samples have defined a broad distribution to the mineralization. Nighthawk has completed several field programs in the area successfully validating and building on the historical reports (see press release dated February 19, 2019).
The JPK gold showings are located at the eastern end of the mineralized corridor about 500 metres east of Treasure Island (Figure 1). Showings are hosted by iron formation similar to the Damoti Lake Gold deposit located 40 kilometres to the south. Historical surface sampling along a 550-metre section of iron formation outcrop returned assays ranging from 5.04 g/t Au to 15.63 g/t Au. Nighthawk’s sampling along a 3.0-kilometre section of the iron formation returned grab samples that assayed up to 12.10 g/t Au, confirming the historical results. No drilling has been reported for this area. JPK remains a vastly underexplored target with significant upside potential, like most of the Treasure Island – Laurie Lake Mineralized Corridor.
Developing Canada’s Next Gold Camp
The Indin Lake Greenstone Belt (“Indin Lake”), is home to one of the few remaining under-explored gold camps in Canada – the Indin Lake Gold Camp. It’s host to several gold deposits and showings, the most significant being the past-producing Colomac open pit gold mine, located within the north-central portion of the Company’s Indin Lake Gold Property.
Consolidation of the gold camp began in 2010 and culminated with the acquisition of the Colomac Mine and surrounding mining leases in 2012. Nighthawk has secured all the gold mines, deposits, and showings to become the first company to combine the camp’s best assets and prospective opportunities under one ownership. Follow this link to learn more about our plans for developing the Indin Lake Gold Camp.
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.
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 200 km north of Yellowknife, Northwest Territories, Canada. Nighthawk is focused on advancing the Colomac Gold Project with a current inferred resource of 2.6 million ounces of gold (50.3 million tonnes at an average grade of 1.62 grams per tonne gold), as well as advancing its other regional gold deposits and showings within this largely underexplored Archean gold camp.
The Company has an experienced and dedicated team and is well funded to complete its goals and objectives over the next 12-18 months.
