Geology Comments

Dec 07, 2005 (A Wilson) - The lithologies north of the Hawk Lake granite complex are variously sheared over a width of 750 to 1500 m. The north limit of the shear is the north contact of the main sedimentary unit and within 100 m f this contact towards the north. The south limit is marked by the supracrustal-granite contact.

Lithology

Lithology Comments

Dec 07, 2005 (A Wilson) - Stripping has exposed a sequence of intense shearing. The chlorite schist and chlorite-sericite-ankerite schist are intruded by sheared quartz-feldspar porphyry dikes. The quartz veining has been extensively disrupted to form a quartz vein breccia.

Mineralization

Mineralization Comments

Dec 07, 2005 (A Wilson) - Grab samples collected by Corona Corporation returned values up to 17 g/t Au. The highest gold values are returned from areas of ankerite-pyrite alteration. The best assay value was 3.1 g/t Au over 0.8 m.
