The Muus Project is situated on the two major regional trends hosting IAMGOLD’s Nelligan and Northern Superior Resources’ Lac Surprise to the south, and IAMGOLD’s Monster Lake to the north with excellent highway and road access. The Project covers approximately 51,000 hectares in five separate blocks of prospective ground in the eastern part of the Abitibi Greenstone Belt. The Project is considered particularly prospective for gold mineralization, as a series of prominent ductile and brittle fault-sets transect the Property, including the Guercheville and Fancamp deformation zones, both of which are associated with numerous past and currently producing precious and base metal mines in the district.
