 to the east is the Odyssey deposit, with mineralization associated with a fault along both hanging wall and footwall contacts of a 300 m wide dioritic intrusive.
 The South Barnat deposit is located to the north and south of the old South Barnat and East Malartic mine workings, largely along the southern edge of the LLCFZ. The deposit that is originally modelled for surface mining evaluation extends on a 1.7 km strike and a width of 900 m (perpendicular to the strike), and from surface to 480 m below surface. The disseminated/stockwork gold mineralization at South Barnat is hosted both in potassic altered, silicified greywackes of the Pontiac Group (south of the fault contact) and in potassic altered porphyry dykes and schistose, carbonatized and biotitic ultramafic volcanic rocks (north of the fault contact).
 The East Malartic deposit (as modelled for the underground mining model) has been previously mined by the East Malartic, Barnat and Sladen mines along the contact between the LLCFZ and the Pontiac Group sedimentary rocks.
 This deposit includes the deeper portion of the South Barnat deposit (below actual pit design). This deposit extends on a 3 km strike and a width of 1.1 km (perpendicular to the strike), and the bottom of the South Barnat actual pit design to 1,800 m below surface. The geological settings are similar to those found in other areas of the property, corresponding mainly to the depth extension of the geological context presented above for the South Barnat open pit deposit.
 The Odyssey deposit is also located at the contact between the LLCFZ and the Pontiac Group sedimentary rocks in the eastern extension of the East Malartic deposit. It extends on a 2 km strike and a width of 500 m (perpendicular to the strike), and from surface to –1,500 m below surface. It is characterized by the presence of a massive porphyritic unit. While the whole porphyritic intrusion is anomalous in gold, continuous zones of higher grade (>1 g/t gold) gold mineralization occur along the south-dipping sheared margins of the intrusion (in contact with the Pontiac Group to the south and the Piche Group to the north). Within the porphyritic unit, gold mineralization is also associated with other geological features, including silica and potassic alteration zones, discrete shear zones, swarms of quartz veins,
