Dec 07, 2005 (K R Kettles) - The northeastern part of the property is underlain by highly altered and sheared mafic metavolcanic flows. In places, these rocks are so highly carbonatized and/or silicified that it is difficult to recognize them as mafic flows. Thin beds of volcanic breccia, banded chert, slate nad iron formation are locally present between some of the flows. The southern and southwestern portion of the property is underlain by conglomerates, greywackes, and slatey greywackes, which overlie the mafic flows with a pronounced angular unconformity. Masses and dykes of quartz porphyry have been observed in several places on the property. Late diorite dykes are also common. In the southern part of the property, tongues of granodiorite from the McKenzie-Gold Eagle Stock extend northward into the sediments.

Dec 07, 2005 (K R Kettles) - The altered mafic metavolcanic flows have been observed to be variolitic pillowed flows and massive flows in places. They contain interflow units of volcanic breccia, banded chert, slate, and iron formation.

Dec 07, 2005 (K R Kettles) - The No. 1 Vein, which strikes S71 degs E and dips 70 degs S, occurs in a zone of carbonatized mafic metavolcanic rocks. The zone ranges from 2.4 to 4.6 m in width, has been traced for about 160 m, and contains lenses and stringers of quartz as wide as 15 cm. Generally, the veins are about 5 cm wide, and contain small amounts of tourmaline and pyrite. Carbonate occurs as lenses in the zone. Surface samples over a length of 76.25 m returned assays that ranged from 0.04 to 0.13 opt Au. Several drill holes were put down, but with one exception, yielded only low values. One hole returned 1.0 opt Au/1.5 m and 0.69 opt Au/5.34 m. Diamond drill holes on both sides (E and W) of the hole which intersected good gold values did not intersect any significant gold mineralization.
Dec 07, 2005 (K R Kettles) - The mafic metavolcanics have been silicified and carbonatized.
