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 zone is underlain by interbedded oxide-sulphide facies iron formation, metasediments and mafic flows. The southern part of the zone terminates at the contact with a unit composed of felsic tuffs and intermediate to felsic metavolcanics. Low gold values up to 26 ppb are recoreded in this zone associated with altered mafic flows, quartz veins and iron formation.
Dec 07, 2005 (A Wilson) - Low but elevated gold values were obtained from soil sampling.
