The Iris Zone is located 1.5 km north of the OGD in the most northeastern part of the property.
Foundation discovered the high-grade gold mineralization (8.39 g/t gold over 11.0m) southwest of Iris Lake during its 2011 winter drilling program. Further drilling in the summer 2011 returning bonanza-grade ( e.g., 254.0. g/t Au over 0.50m) to high-grade (e.g., 7.05 g/t Au over 3.20m) gold expanded the Iris Zone to approximately 25 to 70 metres in width and 630 metres in length.
The Iris Zone area is underlain primarily by mafic and felsic metavolcanic rocks. Numerous dikes and sills of quartz-feldspar and feldspar porphyries have been emplaced within this mafic-felsic volcanic rock package. All these rock types have been variably altered (silica, hematite, chlorite, epidote), mineralized (pyrite and chalcopyrite) and deformed by up to 350 m wide and 2,100 m long Iris Lake Deformation Zone (ILDZ). The ILDZ is a northeast-striking structure with alteration similar to the North Coldstream Shear Zone (NCSZ) structure hosting the OGD located 1.5 km south of the Iris Zone.
Approximately 3,849 metres of drilling has been carried out on the Iris Zone and further drilling will be conducted to further expand the zone.
