Dec 07, 2005 (K R Kettles) - This peninsula is underlain by felsic tuff and by bodies of carbonatized, fuchsitic mafic rocks. An east-west striking zone at least 30 m wide of these altered mafic rocks has been trenched and diamond drilled and was found to carry low values in gold and significant values in silver. The altered mafic rocks are cut by quartz veins up to 30 cm wide that contain minor disseminated pyrite in the veins and the wallrock. Apparently the gold/silver values occur in both veins and wallrocks.

Nov 21, 2014 (K R Kettles) - The best gold value in diamond drilling was 0.10 oz/ton (3.429 g/tonne) Au over 1.52 m. Typical intersections assayed 0.02 to 0.04 oz/ton (0.686 to 1.371 g/tonne) Au over 1.52 m. Silver values ranged up to 4 oz/ton (137.14 g.tonne) Ag.
Dec 07, 2005 (K R Kettles) - The mafic rocks are carbonatized and rich in fuchsite, and rocks adjacent to the veins carry scattered pyrite.
