The Corner Bay property is owned by CBay Minerals which in turn is jointly owned by Nuinsco Resources Limited and Ocean Partners Holdings Limited and consists of one block of 17 contiguous claims totalling 184 ha surrounding a mining lease covering an area of 61 ha. Campbell Resources Inc. started development of the high-grade Corner Bay deposit in 2007 but due to the financial problems development ceased in 2008. The property also has exporation potential as 4 other zones have been identified. The Corner Bay area is characterized by porphyry copper mineralization and shear zone related copper mineralization commonly associated with dykes apparently related with Chibougamau Pluton.

In 2008, Campbell started underground development as part of an underground bulk sample program but the bulk sample was not extracted due to financial difficulties. Some mineralized material from the development was extracted and processed at the Copper Rand mill. A ramp was driven from surface to a depth of 115m. Three levels were opened and drifts were driven to provide access to the bulk sample area. As of 2014 the underground workings are currently flooded up to the portal opening and the plan was to put the mine into production by 2016.

The Corner Bay deposit is considered to be the first economically significant discovery on the south flank of the Lac Doré complex. Twenty-six years of exploration, mainly by M. Flanagan of Corner Bay Exploration Ltd., resulted in the discovery of the Corner Bay deposit in 1982 by a joint venture between Corner Bay Exploration Ltd. and Rio Algom Inc.

The Corner Bay Property is located on the southern flank of the Lac Doré Complex. It lies at the contact with an intrusive breccia, a transition between the Chibougamau Pluton and the Lac Doré Complex. On surface, a 300 m to 450 m wide band made of pyroxenites, gabbros, and magnetitites associated with the bedded series separates this important breccia from the gabbroïc anorthositic sequence which represents the most important lithology on the Corner Bay Property. The Corner Bay area is characterized by porphyry copper mineralization and shear zone related copper mineralization commonly associated with dykes apparently related with
Chibougamau Pluton.
