Dec 07, 2005 (A Wilson) - Deformation and alteration styles of the western MDZ, immediately west of Macassa Creek, are similar to the central MDZ. However, the intensity of strain and alteration decreases further to the west approaching the contact with the Pukaskwa Batholith. The MDZ swings with the stratigraphy, striking approximately 220 at Scuzzy Little Lake where stretching lineations plunge to the west. Folds, crenulations and kinkbands are not as common as in the central MDZ. The Scuzzy Little Lake area lies within the contact metamorphic aureole of the Pukaskwa Batholith.

Dec 07, 2005 (A Wilson) - The showing is composed of a chlorite-sericitized-quartz stringer veined shear zone within sandstones.

Dec 07, 2005 (A Wilson) - Four grab samples collected in 1987 returned assays ranging from 0.1 to 0.3 oz/t Au. A 2-3 ft wide stringer zone with 4% to 7% pyrite and arsenopyrite gave values in the 0.01 to 0.13 oz/t Au. A drill hole completed in 1987 returned assays ranging from 0.02 oz/t Au to 0.38 oz/t Au all over 1 ft. A dril lhole completed by Noranda Exploration in the vicinity returned a best assay of 2.4 g/t Au over 1 m.
