O3 Mining Inc.

The Cadillac Break property group stretches for 35 km along the Cadillac Break, a regional fault zone separating a mostly volcanic terrain and related intrusive rocks on the north, from a sedimentary terrain on the south. Several past producers and recent discoveries are spatially associated with the Cadillac Break and the region has produced one hundred million ounces of gold since the early 1900´s.

O3 Mining´s large property package hosts a variety of geological environments favourable to gold mineralization including shear-zone, gold-rich massive sulphide, porphyry gold-copper and skarn, and disseminated gold. The property group hosts four historic gold deposits: Orenada, Mid-Canada, Akasaba, and Sleepy.

Recent exploration work has focused on the Orenada property, located approximately 4 km southeast of Val d´Or. Orenada hosts two near surface vein-type gold deposits, Zone 2 and Zone 4, and in 2017 a 45,000 metre drill program intersected the gold vein system for more than 2.5 km along strike, centered around the Zone 4 open pit. The drilling has increased the strike length of the deposits by more than 300% over the previously known dimensions and the gold mineralization remains open along strike and at depth.

In June 2018, a resource estimate at Orenada Zone 2 and Zone 4 was released with Indicated Resources of 3.8 Mt at a gold grade of 1.6 g/t and an Inferred Resource of 2.1 Mt at a grade of 1.9 g/t (0.4 g/t gold cut-off grade for open pit and a 2.0 g/t cut-off for underground).

Updated resource contains approximately 194,500 ounces Indicated at 1.6 g/t gold and 126,300 ounces Inferred at 1.89 g/t gold from Orenada Zones 2 and 4 (0.4 g/t to 2.0 g/t cut-off).
