Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The prospect is underlain by units of massive and pillowed basalt and mafic to intermediate tuff units. Thin quartz porphyry dykes intrude the sequence. The metavolcanic units are foliated at approximately N70deg.W and dip 45 deg. to 70 deg. to the southwest. Thin oxide facies iron formation units have been recognized in drill core to the northeast of the auriferous zones. DEPOSIT DESCRIPTION: Three drill holes intersected what appear to be at least 3 parallel to subparallel auriferous zones. These zones are in tuff units which contain quartz-carbonate stringers.
