Northstar files NI43-101 Technical Report on Bryce Gold Property, Ontario

Apr 28, 2022

Northstar Gold Corp. (CSE: NSG) (NSGCF: OTCQB) ("Northstar" or the "Company"), announces the Company has completed an Independent NI43-101 Technical Report for its Bryce Gold Property ("Property") located 47 kilometres south of Kirkland Lake in Northeastern Ontario. Northstar commissioned Ronacher McKenzie Geoscience ("Ronacher McKenzie") to complete the report for the purpose of review and voluntary disclosure of relevant information about the Property following a recent airborne LiDAR survey and Fall 2021 surface exploration program covering the Bryce Gold Property.

Bryce Gold Property Highlights

  • 100% owned, 4,650-hectare property situated on the western extension of the Ridout Break, 65 km east of the Juby Gold Project, 50 km southeast of the Young Davidson Mine (Figure 1) and 35 kilometres south of Northstar's flagship Miller Gold Property.

  • Property hosts a variety of deposit types including porphyry related Au-Cu (Sunday Creek Porphyry), Au-rich Cu-Pb-Zn volcanogenic massive sulphides (Pike Lake Zone) and lode gold systems within an Abitibi multi-stage Archean porphyry / volcanic centre environment.

  • 22,382 metres drilled by Northstar in 68 diamond drill holes from 5 phases of drilling between 2009 and 2013, covering only a small fraction of the total Property area. 

  • 300 metre x 1500 metre Au-Cu Sunday Creek Porphyry discovery hosts a large scale stockwork-type Au-Cu porphyry system with widespread stringers and veins of high-grade gold mineralization open in all directions and expanding towards surface. Drill holes BG10-41 and BG12-65 returned 3.95 g/t Au over 5.5 metres, including 12.91 g/t Au over 1.5 metres and 0.86 g/t Au over 80 metres (including 2.09 g/t Au over 25.5 metres), respectively and drill hole BG13-68 averaged 1.08 g/t Au over 56 metres (including 25.13 g/t Au over 2.0 metres).

  • The nearby Pike Lake Zone (Figure 2) hosts a series of stacked lenses of gold-bearing semi-massive pyrite and sphalerite along a volcanogenic sedimentary exhalite horizon. Drill hole intercepts include 2.36 g/t Au, 3.37 g/t Ag and 1.87% Zn over 15.9 metres, including 7.89 g/t Au, 11.18 g/t Ag and 3.77% Zn over 2.4 metres (DDH BG11-47).

  • Regional fault structures such as the Palmer-Vaughn-Estival "PVE" break hosting anomalous gold have been identified on surface, which could represent the eastern extension of the Ridout deformation zone. 

  • Several large IP targets and conductors remain untested.

  • Potential for substantial near surface bulk tonnage gold resources around felsic intrusive centers.

  • Several major, northeast-trending structures were interpreted from a 2021 LiDAR survey and magnetic survey in the northern and western part of the Property. Follow-up prospecting, sampling and mapping along the major northeast-trending fault ("PVE Fault") and splays is warranted.

  • A $528,500 exploration program including geological modeling, incorporating property-wide historic and Northstar geological data, and diamond drilling on the Sunday Creek and Pike Lake areas to further assess gold-bearing zones is recommended by Technical Report QP Trevor Boyd, PhD., P.Geo. 

  • Northstar's options to advance the Bryce Gold Property include a possible earn-in agreement or spin-out transaction. 

  • The Bryce Gold Property NI43-101 Technical Report can be viewed on Northstar's website and is filed on SEDAR.

2021 Surface Exploration Program

Northstar completed a geological mapping program on the Bryce Gold Property in September and October, 2021. Mapping was focused on the area between Honeymoon Lake and southeast of Pike Lake (Figure 3), with a focus to enhance volcanic stratigraphy understanding, determine surface locations of porphyry dikes and bodies, and identify prospective deformation zones. 

The main rock types observed were intermediate volcanic rocks that display great variability from massive flows and pillowed flows to hyaloclastites, flow breccias, amygdaloidal flows and tuffs, lapilli tuffs, tuff breccias and pyroclastic breccias, indicative of a dynamic volcanic centre environment.

Shear zones were delineated but their full extent could not be mapped due to lack of outcrop. Feldspar porphyry sills and dikes were also observed and are interpreted to be spatially associated with the shear zones.
