Mar 18, 2008 (Mark Puumala) - The Karl-Zeemel Zone 8 showing is located at the boundary between rocks of the predominantly mafic to ultramafic metavolcanic Opapimiskan unit of the McGruer assemblage, and the metasedimentary Zeemel-Heaton assemblage (based on nomenclature of Thurston, Osmani and Stone (1991)). The metasedimentary sequence is located to the south of this occurrence, while the mafic to ultramafic metavolcanic-dominated sequence is located to the north. The metavolcanic assemblage is approximately 650 m wide and is also bounded to the north by metasedimentary rocks of the Zeemel-Heaton assemblage. Mapping by Huston (1988) indicates that bedding and foliation in the area of this showing are generally subparallel, striking approximately 300 with near-vertical dip. Huston (1988) also reports the presence of folds with axes that consistently plunge 18 to 20 degrees to the northwest. Shearing is also reported to be common in the metavolcanics and banded iron formation/chert units, with shearing planes generally subparallel to the regional foliation and fold axes. This occurrence is based on the results of Power Explorations diamond drill hole KZ-87-15, which was reported by Huston (1988) to have intersected 1.16 m of garnetiferous wacke that contained trace to 1% pyrrhotite and assayed 0.041 oz/ton. The surface expression of this zone was described as a group of gossanous shear zones in clastic metasedimentary rocks. These shears are mineralized with 1% pyrite and trace arsenopyrite and pyrrhotite and grab samples of this material assayed up to 280 ppb Au (Huston 1988).
