Oct 10, 2006 (Mark Puumala) - The rocks of the Wottam Lake area are dominated by a thick sequence of metasedimentary rocks described by Wallace (1981) as predominantly monotonously intercalated wacke and mudstone. This sedimentary sequence also contains numerous horizons of oxide, carbonate and/or silicate facies iron formation. Some of these iron formation units have considerable thickness (i.e., up to 150 m), with the most notable iron formation being located at the eastern end of Miminiska Lake. This iron formation thins considerably toward the northeast, and several thinner (typically <10 m) iron formation horizons have been mapped to the south (Needham 2005). The metasedimentary sequence conformably overlies a thick, predominantly mafic metavolcanic sequence that is located to the south. A second predominantly mafic metavolcanic rock sequence interpreted by Wallace (1981) to overlie the metasedimentary rocks has also been mapped to the north. A number of large felsic intrusions occur to the north (Cluff Lake Stock, South Bay Stock and Troutfly Lake Batholith) and south (Kawitos Lake Batholith) of these supracrustal sequences. Mapping by Wallace (1981) indicates that sedimentary bedding in the Wottam Lake area typically strikes in an east-northeasterly direction, with moderate to steep northward dip. Further west, in the vicinity of Miminiska Lake, bedding stikes approximately east-west with near-vertical dips. A number of approximately easterly-trending isoclinal folds are interpreted by Wallace (1981) to occur within the metasedimentary sequence. These include a synclinal structure with an axial trace that passes through Wottam and Goss Lakes, and a second syncline with an axial trace that extends from an area north of Miminiska Island toward Seagreen Lake. Needham (2005) has has indicated that strong foliation is present at numerous locations throughout the Wottam Lake area. The foliation is typically parallel to sedimentary bedding, with dips ranging from 50 to 80 degrees to the north. However, it was locally observed to be 10 to 20 degrees oblique to bedding. Notable locations with strong foliations include the northern sedimentary/volcanic contact and an area approximately 200 to 300 m north of Wottam Lake associated with the WSaspy3 (International) occurrence. Outcrop-scale isoclinal folds and localized arsenopyrite mineralization are commonly observed in the strongly foliated sedimentary rocks. A number of major northeast-striking faults paralleling Ferguson Creek have also been mapped in the area by Wallace (1981). Needham (2005) indicates that gold in this area is typically associated with axial planar shear zones mineralized with pyrrhotite, pyrite and arsenopyrite. The host rock is typically strongly foliated/sheared magnetite bearing silicate to oxide iron formation.

Oct 10, 2006 (Mark Puumala) - The Goss Lake prospect is hosted within an east-northeast striking metasedimentary rock sequence. Rocks in the immediate vicinity of the deposit have been mapped as mudstone, phyllite, slate, quartz-sericite schist, lithic and arkosic wacke, garnetiferous and non-garnetiferous quartz-feldspar-biotite schist, amphibole-garnet-biotite iron formation, grunerite-hornblende iron formation and banded magnetite-quartz-chert iron formation (Mason and White 1995). Mineralization, consists of pyrrhotite, arsenopyrite and visible gold, and is confined to the iron formation and quartz-filled tension fractures within it. Pyrrhotite occurs in disseminated foliation-parallel layers up to 2 cm wide, while arsenopyrite occurs as megacrysts of up to 1 cm. The sulphide mineralization is interpreted to be related to replacement of iron oxides caused by the introduction of sulphide and gold-bearing hydrothermal fluids. Quartz veins are also reported by Mason and White (1995) to be associated with folded iron formation. The quartz veins are typically oriented parallel to axial planar cleavage and are best developed in proximity to the fold axes. The gold-bearing zones are also indicated by Nedham (2005) to be variably silicified, garnetiferous, with amphibole and chlorite/sericite alteration. It was also noted that geophysical survey data appear to indicate that the gold mineralized horizons are associated with a low magnetic response. Three gold mineralized zones have been identified by Neal (1987), with gold concentrations decreasing with depth. Zone A contained 3 pods, one pod had grades as high as 0.34/6.0 (oz per ton/feet), second pod graded up to 0.64/4.4 and third pod had grade up to 0.48/4.5. Zone B had 4 small pods which results from all samples below the cut-off grade of 0.2 oz/ton over 5.0 ft. Zone C had 3 pods with assay results ranging up to 0.9/12 ft. Needham (2005) reports that Tandem Resources calculated a mineral resource totaling 278,220 tonnes with an average grade of 7.41 g.t Au in 1985.
