Dec 07, 2005 (A Wilson) - This area is interpreted to be the westward extension of the Rook Lake Deformation Zone. The strike length of the RLDZ is 8 km and the maximum width is 1 km. The RLDZ is centred within a clastic metasedimentary rock sequence which exhibits sheared contacts with felsic intrusive rocks to the north and mafic metavolcanics to the south. The style of deformation and alteration observed in the RLDZ is similar to, yet not as intensely developed as the MDZ. The penetrative foliation strikes 285, dips moderately steeply to the north. Variable trending, moderately to steeply plunging stretchin lineations are commonly obscured or overprinted by crenulation lineattions. The RLDZ possesses structural characteristics similar to the other deformation zones in the belt. Felsic intrusive dikes/sills are common and concentrated within the central and northern parts of the zone, ranging in thickness from centimetres to several hundred metres.

Dec 07, 2005 (A Wilson) - The occurrence consists of a 6 m by 9 m long exposure of quartz veins which contain chalcopyrite, pyrite, sphalerite, galena, fluorite and pyrrhotite. These veins exhibit open-space filling textures such as crystal-filled vugs and brecciated wall rock along the vein margins. The host rocks ares strongly silicified wackes which are foliated and locally kinked. To the immediate east of the veins is a 3-4 m wide north-trending diabase dike which is foliated adjacent to the vein structure and is cut by small calcite + galena veinlets. Diamond drilling intersected several narrow quartz-carbonate veins, brecciated quartz veins and a 3 ft wide brecciated quartz vein containing hemaltite, pyrite and chalcopyrite.

Dec 07, 2005 (A Wilson) - Grab samples collected by the OGS in 1985 returned values ranging from 235 pm Zn to 14.3% Zn in veins, and 88 ppm Zn in silicified wall rock. Lead values ranged from 37 ppm to 3.55% Pb. The best Cu value was 7050 ppm Cu. Grab samples collected by Muscocho returned Pb values up to 220 ppm.
