Geology Comments

Dec 07, 2005 (K R Kettles) - Most of the property is covered by swamp and overburden. A wide band of sediments underlies most of the property. Good exposures of contorted iron formation are present on the shore of Balmer Lake. The northern part of the property is underlain by a 300 m wide body of quartz feldspar porphyry, locally called the 'Brewis Porphyry'.

Lithology

Lithology Comments

Dec 07, 2005 (K R Kettles) - The north part of the property is underlain by a 300m wide body of quartz feldspar porphyry, locally called the 'Brewis Porphyry'. This unit is a distinctive dark grey rock with prominent glassy quartz eyes and white albite phenocrysts.

Mineralization

Mineralization Comments

Dec 07, 2005 (K R Kettles) - In DDH 14 drilled in 1946, a narrow section of drill core containing a quartz vein assayed 3.41 opt Au. A series of holes on either side of the original hole failed to intersect the vein. A wide quartz porphyry dike containing sparse arsenopyrite mineralization returned low values in gold. Scattered low gold values were obtained in other drill holes.
