Mineralization Comments

Dec 07, 2005 (G Meyer) - Overburden stripping, of an area approximately 75 m x 7 m, has exposed a narrow carbonatized zone with at least two small quartz veins, hosted by mafic volcanic rock. The best exposure was at the middle of the trench where the alteration zone, with two small quartz veins, has a width of 2 m. The alteration zone and quartz veins strike 144 8 and the quartz veins dip 748 to the northeast. Five samples were collected across the carbonate alteration zone at the site with the best exposure. Three samples of altered material assayed 287 ppb, 12 ppb and 2312 ppb Au and two samples of quartz vein material assayed 2576 ppb and 543 ppb.
