Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurrence is underlain mainly by pillowed and variolitic basalts. Stratigraphic tops are to the northwest. The flows generally strike northeast-southwest and dip subvertically. Foliation is generally parallel to subparallel to the bedding. Thin interflow lenses of intermediate tuffs are present in the sequence. A large mafic to ultramafic intrusion outcrops to the south of the occurrence. DEPOSIT DESCRIPTION: Gold mineralization apparently occurs in narrow quartz cabonate stringers in mafic volcanic rocks.
