The most prominent geological feature on the Vanguard Property is a large, 5km by 2km, rhyolite dome complex, situated in the western portion of the property. This complex trends WSW to ENE, is an antiform, and probably plunges doubly to the ENE and WSW. The rhyolite dome complex is dominated, especially to the west, by massive fine grained rhyolite flows and quartz-sericite schists. Rhyolite breccias and lapili tuffs predominate at the periphery and in the eastern areas of the complex. Components within this rhyolite complex are several small basins with graphitic sediments encountered in drill holes (Cominco 1970, Heggie 2005). At the western boundary of the property the rhyolite complex is cored by felsic to mafic intrusive rocks.
A Qualified Person has not done sufficient work to verify the historical drill core sampling and reported drill core intercepts reported herein.
At Vanguard East rocks are exposed over a 50 by 140 meter area in a WSW direction and are similar to Vanguard West. Several sub-parallel bands and lenses of chert-carbonate are from 1 to 10 meters wide and are enclosed in altered mafic metavolcanic rocks. A 2 by 20 meter lens of massive sulphide is exposed in the chert horizon. In the northern and western part of the exposure up to 25 meters of fragmental intermediate to felsic metavolcanic rocks are exposed.
Vanguard West mineralization has been described as a steeply dipping zone 600’ deep, 150’ long and up to 20’ wide with a rake of 65 degrees to the west (Hodgkinson 1968). Vanguard East mineralization is approximately half the size of Vanguard West. Drill holes with anomalous metal values have been intersected as far as 700 m west of Vanguard West (Canadian Golden Dragon drill hole VW04-09, 1991).
