Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: This 'vein' is an auriferous zone that appears to lie within and along rhyolite flows mapped by Riley (1978). The rhyolite strikes roughly N80 deg. W as does the 'vein', and the rhyolite occurs within an area of intermediate pyroclastic rocks. The zone was sampled by T. McVeigh (H.G. Young, 1941) and was apparently traced 450 m, from the northeast corner of the claim KRL 468157 northwestward into the southwest part of KRL 468158. This ' No. 2 vein' was noted by Flaherty (1944), who described it as 'a wide carbonate zone in porphyry (rhyolite)'. The porphyry is highly fractured and brecciated '(flow breccia?)' and the rock is largely replaced by silica and carbonate. All of the above are cross cut by late irregular veinlets of quartz, with patches of green mica (mariposite) in places. Sulphide mineralization amounts to 3% to 10% and the rock weathers to a rusty surface. DEPOSIT DESCRIPTION: A zone 450 m long and at least 50 cm wide, in altered felsic (flow ?) breccia carries gold values. GEOCHEMICAL DATA: This breccia is enriched in chromium (fuchsite).
