Northstar samples high-grade copper at Cam Copper Mine - Miller Gold Property

Jul 6, 2023

"Northstar's limited Cam Copper Mine sampling program substantiates a high-grade Critical Minerals copper component to the spectrum of alkalic gold-telluride-copper zones at the Miller Gold Property," states Brian P. Fowler, P.Geo., Northstar's President, CEO and Director. "Northstar is fully permitted to drill test the down plunge extension of the Cam Copper massive sulphide zones and, in addition to expansion drilling at the Allied Gold Zone, is formulating exploration plans targeting similar high-grade massive sulphide copper zones along strike southeast of the Cam Copper Mine site."

Northstar Gold Corp, is pleased to announce results of a recent surface sampling program at the historic Cam Copper Mine site on the Company's 100%-owned, flagship Miller Property, situated 18 km southeast of the town of Kirkland Lake, Ontario. The Cam Copper Mine is a road accessible satellite high-grade copper system situated 2.4 km southwest of the Allied Gold Zone, the advanced, near-surface bulk-tonnage alkalic gold-telluride exploration target being actively explored by Northstar (Figure 1).

High-Grade copper assays ranging between 0.99% and 31.8% copper were returned from 19 select surface grab samples containing massive to semi-massive sulphides (including massive chalcopyrite and bornite) and collectively weighing 43.39 kg, recently collected near the historic Cam Copper Mine site on the Miller Property in Pacaud Township. The weighted average grade of the 19 select samples collected from the historic muck pile and bedrock exposure near the historic shaft was 14.0% copper (Table 1). 

In addition to high-grade copper, one select sample that assayed 31.8% copper also returned 452 g/t silver, suggesting silver can also be a significant mineralization component. 

The Cam Copper Mine reportedly hosts two separate lenses (Zone 1 and Zone 2 - Figure 2) of massive copper sulphides about 40 metres apart striking and plunging southeast along the contact with the Round Lake Granite Batholith. Underground development took place between 1929 and 1953 which includes sinking of a 220' (66.7m) vertical shaft with 213' (64.5m) of cross cutting and 267' (80.9m) of drifting. The recent surface sampling results verify historic reporting of a 1955 shipment of 346 tons of hoisted underground ore which produced 43,411 lbs. of Cu1 at a Noranda smelter for a recovered grade of 6.3% Cu. The ore was shipped directly from the mine site to the smelter without requiring further concentration in a mill. A previous 1948 shipment of 22 tons of ore to Noranda reportedly graded 12.72% Cu, 0.84 oz/t Ag and 0.03 oz/t Au2, presumably from Zone 1.
