Northstar Intersects near-surface high-grade near Kirkland Lake

Sep 3, 2020

Northstar Gold Corp. is understandably excited about its latest drill numbers. The company reports that Vein 1 and Allied Syenite drill results from the recently completed Phase I drill program on the Company's 100%-owned Miller Gold Property, situated 18 kilometres southeast of the town of Kirkland Lake and Kirkland Lake Gold's Macassa gold mine. Planet Syenite drill results are expected to be available later this month.

The primary objective of the Phase I drill program was to confirm and expand known near surface, Kirkland-style high grade gold/telluride mineralization and portions of a historic estimate within the Vein 1 Zone. The Phase I program not only succeeded in expanding the near surface, high-grade gold mineralized zone but it also discovered several additional near surface gold zones (Veins 2, 3 and 4 in the hanging wall of Vein 1, now collectively referred to as the Allied Syenite Gold Zone), highlighting the potential for the delineation of 43-101 compliant near surface bulk tonnage gold mineralization.

Phase I Drill Program

Northstar resumed Phase I drilling on the Miller Gold Property on June 16th, 2020, after a brief suspension of activities on April 4th, 2020, due to COVID-19 complications, and drilled 15 holes in 2,812 metres to follow-up previously reported Phase IA drill results (2,211 metres in 13 holes) on Vein 1 (18 g/t Au over 3.9m, including 100.0 g/t Au over 0.6m), the new Allied Zone (2.1 g/t Au over 11.6m), and further drill test the Allied Syenite and Planet Syenite near-surface bulk tonnage gold targets. Phase IB drilling was completed on August 4th, 2020, and includes drill holes MG20-40 through MG20-54. Previously reported Phase IA drilling, which ended on April 4th, 2020, included drill holes MG-20-28 through MG20-39. 

All drill core has been logged with samples assayed for gold by AGAT Laboratories in Mississauga, Ontario. Metallic screening was performed on 27 samples associated with core intervals hosting coarse visible gold or gold tellurides. Assay results are pending for 4 drill holes on the Planet Syenite (drill holes MG20-50-53) and 1 drill hole (MG20-54) on the Allied Syenite.

Phase IB drill results are highlighted by:

  • Hole MG20-49 intersected 8.0 g/t Au over 15m, including 19.4 g/t Au over 4.4m, within a larger zone of 1.4 g/t Au over 118.5m between 54m and 172.5m; this intercept highlights the grade potential of the mafic volcanics adjacent to the Allied Syenite contact and demonstrates that bulk tonnage potential extends beyond the boundary of the syenite intrusion.
  • Hole MG20-47 intersected 4.6 g/t Au over 8.0m including 10.2 g/t Au over 3.0m within a larger zone of 1.2 g/t Au over 107.3m between 4.7m and 112m along the western flank of the Allied Syenite; this first hole in the western half of the syenite indicates potential for near surface bulk tonnage 43-101 compliant resources in this area.
  • Hole MG20-45 intersected 4.1 g/t Au over 4.1m and MG20-46 intersected 15.5 g/t Au over 2.0m in the Vein 1 Zone south of the Allied Syenite; this confirms the high-grade nature of Vein 1 Zone, which remains open in all directions.
  • A complete listing of Phase IB drill results is provided in Table 1.

"Northstar is very pleased with Phase I drill results," states Brian Fowler, President and CEO of the Company. "The Miller Gold Property has the signature of a large and robust intrusion-centred alkalic gold system complete with the important elements of a Kirkland-style gold deposit. Drilling continues to identify new high-grade gold-telluride veins / horizons and the near-surface "Allied Syenite Gold Zone" that remains open laterally. We look forward to a substantial Phase II drill program this Fall to significantly enlarge this Zone, further test the Planet and Meilleur Syenites and other newly-defined high-grade exploration targets associated with the main, as-of-yet untested Catharine Fault First Order feeder structure."

Vein 1 Zone South of the Allied Syenite

One of the objectives of the Phase IB drilling program was to follow up on recent and historic high grade intercepts of the Vein 1 Zone in the vicinity of Phase IA drill hole MG20-34 which intersected 18 g/t Au over 3.9m (See June 3, 2020 Northstar News Release) and nearby 2014 drill hole MG14-02, which intersected 5.3 g/t Au over 8.0m. A total of 702m were drilled in 7 closely spaced holes (MG20-40 to MG20-46) with MG20-42 (5.0 g/t Au over 2m), MG20-45 (4.1 g/t Au over 4.1m) and MG20-46 (15.4 g/t Au over 2.0m) intersecting additional near surface high grade gold telluride mineralization within the Vein 1 Zone in the vicinity of holes MG20-34 and MG14-02. These drill results and preliminary data from the recently completed 3D IP survey suggests this higher-grade envelope of tellurides and associated pyrite extends down dip in a north-northeast direction towards the Catharine Fault Zone. 

New Vein 3 Discovery within Larger Near Surface Allied Gold Zone

Drill holes MG20-47 and MG20-49 intersected a new zone around the Allied Syenite intrusion in the immediate hanging wall of the Vein 1 Zone termed the "Vein 3" Zone. Hole MG20-47 intersected significant gold intervals in stacked lenses in the Allied Syenite between 4.7 and 22.1m (1.8 g/t Au over 17.4m in the Vein 2 Zone), 79.3m and 85.5m (3.6 g/t Au over 6.2m in the "Vein 3" Zone) and 104m and 112m (4.7 g/t Au over 8m in Vein 1) within a larger envelope grading 1.2 g/t Au over 107.3m between 4.7m and 112m.

The Vein 3 Zone in hole 47 is characterized by strong pervasive hydrothermal chlorite alteration while Vein 1 could be described as a silicified fault breccia. Gold is often found with Bi or Pb tellurides and sulfosalts associated with chlorite or pyrite filled micro-fractures and is widely disseminated in the syenite. Hole 47 is the first drill hole in the western half of the Allied Syenite and results indicate potential for near surface 43-101 compliant gold resources. 

Drill hole MG20-49 intersected significant amounts of gold associated with pyrite and trace chalcopyrite mineralization, silicification, Fe-carbonate alteration and quartz-carbonate stringers in mafic volcanics and feldspar porphyry dikes between 59.5m and 74.5m (8.0 g/t Au over 15m in the new "Vein 3" Zone), including 19.4 g/t Au over 4.4m and 122.3m and 126.3m (3.0 g/t Au over 4.0m in Vein 1). The intersections are within a larger envelope of disseminated gold grading1.4 g/t Au over 118.5m from 54.0m to 172.5m. The presence of disseminated gold bearing pyrite in the mafic volcanics demonstrate that the bulk tonnage potential of the area extends beyond the boundary of the syenite intrusive as was previously demonstrated with the Vein 2 intercept in hole MG20-38. 

The near surface Allied Syenite Gold Zone remains open laterally, extending from 4m to 98m vertical depth along the western contact of the intrusion. The Allied Syenite could be considerably larger than previously believed as it expands in size at depth towards the southeast where drill holes MG15-18 and MG20-47 failed to reach the contact due to drill limitations.
