Geology Comments

Dec 07, 2005 (A Wilson) - The Mishibishu Deformation Zone (MDZ) is the largest of the deformation zones int he 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 metavolcanic rocks to the north and clastic metasediments to the south. The central MDZ has the highest degree of strain intensity and alteration within the belt. Shear zones are broad and exhibit pervasive deformation and alteration. Mafic metavolcanics in the hanging wall become progressively more strained and altered with increasing proximity to the centre of the zone. Conglomerate clasts are attenuated and only the most competent clasts are discernable from matrix. An intense penetrative foliation strikes approximately 300 and a well developed stretching lineation plunges moderately to the N and NE.

Mineralization Comments

Dec 07, 2005 (A Wilson) - Samples collected by Hollinger in 1938 returned assays of 0.56 oz/t Au over 5 ft. A drill hole completed northeast of the showing intersected 0.11 oz/t Au over 17 ft. Diamond drilling completed by Granges intersected 1.58 g/t Au over 0.5 m, 1.47 g/t Au over 0.5 m,2.23 g/t Au over 0.5 m.
