Dec 07, 2005 (A Wilson) - The Mishibishu Deformation Zone (MDZ) is the largerst of the deformation zones in the belt, measuring approximately 40 km in length and several hundred metres up to 1.5 km in width. The zone is located north of the Mishibishu Lake Stock and lies along the lithological contact of mafic metavolcancis to the north, with clastic metasediments to the south. The Eastern Mishibishu Deformation Zone becomes narrower approaching Lake Superior where the zone transects the external granitoids east of the greenstone belt. Deformation and alteration are less pervasive and shear zones become more dicrete than in the central MDZ. Stretchin lineations plunge to the east. The style of deformation is more brittle-ductile in the eastern MDZ. Alteration is less pervasive than, yet similar to, other zones within the belt.

Dec 07, 2005 (A Wilson) - The occurrence is located within an altered quartz monzonite dike related to the Mishibishu Lake stock. A strong, joint-controlled quartz veins stockwork occurs in the dike and to a lesser degree, in the surrounding chlorite-calcite schist. Copper mineralization is restricted to a 25 cm wide quartz vein located at the contact of a sericite altered, fedspar+quartz porphyry dike and chlorite-calcite schist.

Dec 07, 2005 (A Wilson) - A grab sample collected by the OGS in 1985 returned 2440 ppm Cu and 150 ppb Au. Additional samples collected by the OGS in 1986 returned an assay of 5000 ppm Cu, 21 ppb Au, <2 ppm ag, <10 ppm Pb, <5 ppm Zn, and <1 ppm As.
