Located in the Kenora Mining District of Ontario, the property consists of 112 mineral claim units totalling 1792 hectares in Grummett and Cathcart townships. The property boasts year-round access 192km northwest of Thunder Bay, ON via Hwy 17 and 9km south on a gravel forestry road.
The Phyllis claim block occupies the central portion of a ENE-WSW trending greenstone belt, consisting of Mesoarchean to Neoarchean age mafic to ultramafic rocks. These are bound by granite of varying composition - ranging from tonalite to biotite-granodiorite (Atikokan-Lakehead Sheet Map 2065) as shown in Figure 1. Recent mapping undertaken by the Ontario Geological Survey (Gulliver River Sheet, Map 3370), which includes a small portion of the Phyllis claims, suggests that there is a greater abundance of ultramafic metavolcanics than previously indicated. The regional foliation follows the general trend of the greenstone belt.

The initial cobalt discovery was made in 2010 by Don Dobransky, named the “Phyllis Central” occurrence. This discovery is characterized by an 80m x 60m outcrop and appears as a fairly structureless gabbro, with the exception of an array of narrow quartz veins and veinlets, which have sharp contacts with the country rock and trend roughly NE-SW, and appear to have been intruded relatively recently. The gabbro itself is fine-to medium grained and appears highly altered. The exposed outcrop follows the northern flank of a gentle hill. Earlier excavations focussed in the uppermost parts of the topographic profile. The sampling as seen in Figure 2. This worked confirmed the presence of economic grades of cobalt mineralization up to 0.33% Co (including 1.2% Cu and 0.39% Ni).
