Dec 07, 2005 (A Wilson) - The Scuzzy Little Lake occurrences are found within the western portion of the Mishibishu Lake Deformation Zone (MDZ) where is it about 150 m wide and localized between metavolcanic rocks to the north and clastic metasedimentary rocks to the south. The metavolcanic rocks to the north are amphibolitzed, massive, mafic to intermediate flows with narrow intercalations of felsic metavolcanic rocks. The metasedimentary rocks to the south comprise a series of polymictic conglomerate horizons within a sequence of quartz-rich sandstones and metawackes. Within the MDZ, the mafic metavolcanic rocks are well foliated, chlorite-calcite schists, while the metasedimentary rocks are gritty, quartz-chlorite-biotite-sericite schists. A 1-2 m wide polymictic conglomerate horizon within the southern portion of the MDZ contains highly deformed and rotated granitoid clasts and minor chert-magnetite clasts within a chloritic matrix. The Scuzzy Little Lake area lies within the contact metamorphic aureole of the Pukaskwa Batholith.

Dec 07, 2005 (A Wilson) - Gold mineralization is associated with a 2-3 m wide zone of quartz veining within highly strained, well foliated, siliceous, dark grey to black rock. Away from the highly strained zone, the host rocks are massive, blue-quartz-eye-bearing metawackes. The quartz veins associated with the gold mineralization vary in width from 1-10 cm and are subparallel to foliation. Coarse arsenopyrite crystals occur as 3-4 cm wide haloes about the quartz veins. The quarta veins appear to be barren of sulphide mineralization but locally contain visible gold. This showing consists of 4 individually trnched areas No 1. to No. 4 (west to east). The mineralized zone is cut by a 125 fault (dextral) and a 160 fault (minimal displacement). These localized faults are observed at showing #2.

Dec 07, 2005 (A Wilson) - Wasabi Resources Ltd: A 4 foot channel sample of quartz-arsenopyrite mineralization returned values of 0.2 oz/t Au and 465 ppb Au over 2 ft lengths. Visible gold was observed in one of the trenches. The average free-gold assays obtained from trenches in the #1 (east) exposure are 0.08 and 0.03 oz/t Au over 6 ft. Average assays for trenches in the #1 (west) exposure are 0.087 oz/t Au over 5 ft and 0.034 oz/t Au over 4 ft. One anomalous value of 0.11oz/t Au over 1 ft was returned from #2 showing. Averaged free gold values from trenches in showing #3 returned values of 0.153 oz/t Au over 2 ft, 0.224 oz/t Au over 5 ft, 0.157 oz/t Au over 2 ft. The best assays obtained from diamond drill core were 0.24 oz/t Au over 2 ft, 0.4 oz/t Au over 2.75 ft, 0.036 oz/t Au over 1 ft, 0.178 oz/t Au over 1 ft.

Notes: The shear zone in this area can be divided into two sub zones. To the south, there is a well foliated biotite enriched zone and to the north, there is a strongly foliated locally schistose, chlorite-sericite enriched zone. The contact between these zones is gradational and unconformable with local foliation. The contact between the chlorite alteration zone and the quartz-eye tuff to the north is sharp, whereas the quartz-eye tuff - biotite alteration zone conatct is gradational. Quartz veins show small scale folding and warping in the biotite zone. Brittle deformation in the form of dextral offsets can also be observed. Within the chlorite zone, the quartz veins are highly deformed to the south and become more continuous near the northern contact.
