Point Location Description: Central point between DDH PT93-2, PT93-4 and PT93-6

Location Method: Based on Assessment

Access Description: The property is accessed via the forest access road running northeast from Iroquois Falls. Approximately 30 km along the road, a diamond drill road leads west just north of Dowie Lake. The drill holes are approximately 3.5 km west of the forest access road.

Exploration History

1990: Cross Lake Minerals completed ground magnetometer and electromagnetic (MAx-Min) surveys. This was a follow up to an OGS airborne mag and EM survey (Map 81220). 1993-1994: Diamond drilling by Noranda Exploration - 12 drill holes totalling 3343.8 m (PT93-2 to PT94-11, Pt94-13-PT94-14). Total field magnetic and HLEM surveys were completed. DDH PT93-2 intersected 3 zone with the best being 1.29% ZN over 8.2 m.

Geology Comments

Dec 07, 2005 (D Guidon) - Map P.3398 indicates a band of Archean felsic volcaniclastic rocks trenind easterly from mid Fox Township to the eastern portion of Stimson Township. Mafic to intermediate volcanic rocks lie to the south. A discontinuous band of chemical metasedimentary rocks overlie the felsic rocks that are, in turn, overlain by mafic volcanic rocks to the north. A sample of the felsic volcaic rocks, that hosts the deposit, collected to the south east of the deposit, was dated at 2726 +7/-5 Ma. This would put the deposit in the Deloro Assemblage (Ayer et al. 2002). Locally, diamond drilling appears to indicate a northeast trend to the geology.

Lithology

Lithology Comments

Dec 07, 2005 (D Guidon) - Diamond drill logs describe the deposit to be hosted by metasedimentary rocks or felsic volcaniclastic rocks (tuffs). The upper zone in DDH PT93-2 is within a graphitic sediment with 10-15% py-po either disseminated or as coarse grained aggregates. The second and third zones are within felsic volcanics. Locally, diamond drilling suggests that the geology has a northeast trend.

Mineralization

Mineralization Comments

Dec 07, 2005 (D Guidon) - The upper zone of hole PT93-2 (157.0-165.0 m)contains 8-10% po-py disseminated and narrow 1-2 mm bands and fracture fillings. The main zone has ubout 10% sphalerite. The zone averaged 0.35% Cu over 8.0 m with a high of 5.2% Zn over 0.3 m. The second and third zones of hole PT93-2 (168.0-176.2) contained disseminated sphalerite, minor chalcopyrite and disseminated pyrite. The second zone assayed 1.29% Zn over 8.2 m with a high of 3.66% over 0.2 m. The third zone assayed 0.73% Zn over 6.0 m. The first zone in DDH PT93-4 assayed 0.1% Cu, 2.5%Pb and 3.80% Zn over 6.8 m. The second zone assayed 0.25% ZN over 12.7 m with a zone of 1.27% Zn over 1.6 m. The third zone assyed 1.6% Zn and 0.3% Pb over 2.9 m.
