The Joe Mann Property

The Company has a controlling interest in a contiguous group of claims totaling 6,209.2 ha surrounding the former high-grade Joe Mann gold mine (Dore Copper has a 100% ownership in 3,179.6 ha and a 65% ownership in 3,029.6 ha, as part of the Joe Mann SOQUEM JV) (Figure 1). The property is located 60 kilometers south of the Company’s Copper Rand mill and part of the southern Chibougamau mining camp where Northern Superior Resources Inc. and IAMGOLD Corporation have identified significant gold mineral resources.

The Joe Mann property is located in the eastern part of the Abitibi Greenstone Belt within the upper part of the Obatogamau Formation, within a major deformation corridor known as the Opawica-Guercheville shear zone. The Company has a 100% interest in the former Joe Mann mine, which produced 1.12 million ounces of gold at an average grade of 8.26 g/t from the 1950s to 2007.¹ The deposit has an inferred mineral resource of 680,000 tonnes grading 6.78 g/t Au and 0.24% Cu, which was included in the Company’s Preliminary Economic Assessment (PEA) of its hub-and-spoke operation announced on May 10, 2022.²

A number of gold occurrences and mineralized zones have been identified on the Joe Mann SOQUEM JV Property. No significant exploration work on the joint venture land has been carried out since the late 1990s, except for the Rohault and Norhart gold occurrences where the latest exploration activities took place in 2005.
