Dec 07, 2005 (A Wilson) - 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) - Diamond drilling in the vicinity by Noranda intersected a hanging wall of massive to weakly foliated mafic metavolcanic rocks. The mineralized zone consists of sericitized and silicified intermediate tuffs. The veins and veinlets consist of quartz-carbonate.

Dec 07, 2005 (A Wilson) - Selected grab samples from the trench returned assays of 5.66 g/t Au, 1.37 g/t Au and 1.14 g/t Au. Chip samples from the trench returned assays of 1.03 g/t Au over 1 m, 2.89 g/t Au over 2.9 m. A diamond drill hole appoximately 25 m to the west intersected 1.72 g/t Au over 1 m. Grab samples collected by Murgor Resources in 1996 returned assays ranging from <5ppb to 2.3 g/t Au. Diamond drilling completed by Battle Mountain in 1998 returned assays ranging from 1.34 g/t Au over 0.35 m to 5.78 g/t Au over 0.3 m.
