Dec 07, 2005 (K R Kettles) - Geological description: the occurrence is underlain primarily by mafic metavolcanics of basaltic composition. Pillow structures have been recognized in the area, with flow tops indicated to the north. The volcanics strike approximately E-W and dip steeply to the south. A thin 'tongue' of intermediate tuff is present to the west of the occurrence. Small lenses of chemical metasediments of chert-magnetite composition occur throughout the area. A long NE-SW trending lineament cuts across the area, and may represent a fault. The basaltic flows are cut by numerous quartz-carbonate stringers, and are locally brecciated and cemented with quartz-carbonate. Deposit description: Little information exists about the nature of the occurrence, but it is believed that the gold is located in quartz-carbonate stringers and quartz veins in basalt. The quartz-carbonate veins which occur as narrow fracture fillings and in brecciated zones. They constitute approximately 10% of the rock.

Dec 07, 2005 (K R Kettles) - A grab sample taken in 1971 assayed 0.01 oz/ton (0.343 g/tonne)Au.
Dec 07, 2005 (K R Kettles) - The basalt has undergone varying amounts of silicification and carbonatization, depending on the degree to which it has fractured or brecciated.
