  • 1979 – 1981 diamond drilling, geophysical surveys
  • 1981 growth commenced
• Joe Mann recognized in 1950 with the graduation of mining actions occurring in 1956
  • The Joe Mann mine operated underground throughout three completely different durations from 1956 to 2007
  • In July 2012, Assets Jessie acquired the Joe Mann mine property, however carried out solely floor exploration work
• Cedar Bay was found previous to 1927 by Chibougamau McKenzie Mines Ltd
  • From preliminary discovery to 2013 varied floor and underground drilling campaigns and geophysical surveys undertaken by varied firms
• Colline was first found with mapping and sampling after which drilled within the Fifties with comply with up drilling in 1955.
  • In the1950s a shaft was sunk however the deposit was by no means mined.
  • The deposit was later examined with three drillholes and 6 regional drillholes all through two drilling campaigns in 1984 and 1986/87.
  • Exploration at Colline has been halted traditionally with the invention of and deal with different deposits within the area.

• Nook Bay and Devlin are positioned on the northeastern extremity of the Abitibi subprovince within the Superior province of the Canadian Defend and are examples of Chibougamau-type copper-gold deposits. The Abitibi subprovince is taken into account as one of many largest and best-preserved greenstone belts on the earth and hosts quite a few gold and base steel deposits.
• The Nook Bay deposit is positioned on the southern flank of the Doré Lake Complicated (DLC). It’s hosted by a N 15° trending shear zone roughly steady with a powerful 75° to 85° dip in direction of the west. The host anorthosite rock is sheared and sericitized over widths of two m to 25 m. The deposit is lower by a diabase dyke and is proscribed to the north by a fault construction and to the south by the LaChib deformation zone.
• The Nook Bay deposit consists of three important mineralized lodes (subparallel Important Lode 1 and Important Lode 2 above the dyke, and Important Lode beneath the dyke that make up the majority of the deposit. The Nook Bay deposit has been traced over a strike size to over 1,100 m to a depth of 1,350 m and stays open at depth.
• The mineralization is characterised by veins and/or lenses of large to semi-massive sulphides related to a brecciated to domestically large quartz-calcite materials. The sulphide assemblage consists of chalcopyrite, pyrite, and pyrrhotite with lesser quantities of molybdenite and sphalerite. Late remobilized quartz-chalcopyrite-pyrite veins happen in a large halo round the primary mineralization zones.
• Devlin is a flat-lying, copper-rich lodes-hosted deposit in a polygenic igneous breccia that’s lower than 100 m from the floor. The tabular our bodies have been modelled as 4 practically horizontal lodes: a extra steady decrease zone and three smaller lodes comprising the higher zone. Mineralization is mirrored as a fracture zone usually composed of two or extra sulphide-quartz lodes and stringers. Thickness of the mineralized zones vary from 0.5 m to 4.4 m. It has been diluted throughout modelling to mirror a minimal mining top of 1.8 m.
• The Joe Mann deposit is characterised by east-west placing shear hosted lodes that reach past 1,000 m vertically with mineralization recognized over a 3 km strike size. These shear zones type a part of the Opawica-Guercheville deformation zone, a significant deformation hall slicing the mafic volcanic rocks of the Obatogamau Formation within the north a part of the Caopatina Phase. The gabbro sill hosts the Important Zone and the West Zone on the mine, whereas the South Zone is discovered within the rhyolite. These three subvertical E-W (N275°/85°) ductile-brittle shear zones are sub-parallel to stratigraphy and to at least one one other, with as much as 140 m to 170 m of separation between them. These shear zones are hosted inside a stratigraphic bundle composed of iron-magnesium (Fe-Mg) carbonate and sericite altered gabbro sills, sheared basalts, and intermediate to felsic tuffs intruded by varied felsic intrusions. The Joe Mann gold mineralization is hosted by decimetre scale quartz-carbonate lodes (Dion and Guha 1988). The lodes are mineralized with pyrite, pyrrhotite, and chalcopyrite disposed in lens and lodelets parallel to schistosity, and infrequently seen gold. There are another minor, mineralized buildings, e.g., North and South-South Zones, with restricted vertical and horizontal extensions.
