Northstar Drills Multiple Horizons of High-Grade Volcanogenic Massive Sulphides at Historic Cam Copper Mine

Northstar Gold Corp. announces preliminary results from a Phase I diamond drill program at the historic Cam Copper Mine, a small-scale, former high-grade copper producer on the Company's 100%-owned Miller Copper-Gold Property, situated 18 kilometres southeast of Kirkland Lake. The Cam Copper Mine is a road accessible satellite high-grade volcanogenic massive sulphide (VMS) copper system situated 2.4 km southwest of the Allied Gold Zone, the advanced, near-surface bulk-tonnage alkalic gold-telluride exploration target also being actively explored by Northstar. Cam Copper Mine occupies the southern portion of the historic Boston Creek Copper Trend (Figure 1).

Northstar completed 720 metres of drilling in 4 diamond drill holes (CC01-23 to CC04-23 — Figure 2) at Cam Copper Mine between October 20th and October 30th, 2023. The Company reports all 4 drill holes intersected lenses of Cu-rich volcanogenic massive sulphides, including massive and stringer chalcopyrite over 2.45m in drill hole CC03-23 between 116.55m to 119m in Zone 2 (Photos 1 and 2).  A 3D Cam Copper Mine image illustrating Phase I drill results and massive sulphide intercepts is provided in Figure 2. Analytical results for drill holes CC02-23 to CC04-24 are pending and expected shortly.

The Company reports the following assay results received from drill hole CC01-23 (Photo 3): 

• 3.12% Cu over 3.6m from 25.0m to 28.6m including 19.45% Cu and 14.85 g/t Ag over 0.5m from 28.1m to 28.6m in Zone 1 (Photo 3)

• 12.71% Cu, 0.62% Zn, 0.44% Pb, 16.47 g/t Ag over 0.75m from 107m to 107.75m in Zone 2

• 5.91% Cu over 1.5m from 135.0m to 136.5m including 9.92% Cu over 0.5m from 135.5m to 136m in Zone 3 

Massive sulphides were intersected in Zone 2 well below the 200' level of the historic mine workings at 130m vertical depth in drill hole CC02-23. Zone 2 appears to be expanding in thickness down plunge towards the southeast, and all zones remain open along strike and at depth.

Management Commentary

"Northstar's 2023 sampling and preliminary Phase I drill results substantiate the presence of a robust, multi-horizon high-grade copper VMS system at Cam Copper Mine, exhibiting excellent expansion potential," states Brian P. Fowler, P.Geo., Northstar's President, CEO and Director. "Northstar is fully permitted and positioning to explore the southeast strike and down plunge extensions of the Cam Copper massive sulphide zones through Phase II drilling."
