Sudbury 2.0 Project

Cobalt Hill and Lake Zone

The adjoining Cobalt Hill and Lake Zone occurrences are an IOCG-subtype exploration target with gold, copper, cobalt, nickel and REE mineralization. The occurrences are located 1.2 km apart and occur along the same mineralized structure.

The property consists of a 3.5 sq. km block of mineral leases with historic high-grade gold and copper drill intersections. The property was mainly explored for gold and copper during the 1980’s. Inventus’ geological interpretation and first phase of drilling on the property in 2021 has indicated exploration potential for an IOCG-subtype mineral system.

A 3D induced polarization survey (3D IP) was conducted in August 2021 to target sulphides that correlate with the mineralization. The 3D IP detected a large 600-m north-south by 500-m east-west anomaly that is open at depth and correlates well with Inventus’ surface mapping and drill intersections.

2021 Drill Highlights include:

  • 18.5 m of 6.6 g/t gold, 0.76% copper and 180 ppm cobalt (Lake Zone)

  • 44 m of 1.3 g/t gold, 400 ppm cobalt and 200 ppm nickel, including 7 m of 4.4 g/t gold, 900 ppm cobalt and 300 ppm nickel (Cobalt Hill)

“The relative proximity of Cobalt Hill to the SIC, the ubiquitous presence of small Sudbury-type sulfide inclusions in pyrite in the Cobalt Hill quartz veins, the comparable salinity and homogenization temperature of fluid inclusions in these veins to those of metal-rich fluids of the SIC, and the presence of chromian muscovite, imply a spatial relationship of the veins to Sudbury-type base metals and to a Cr-rich mafic or ultramafic intrusion at depth”
