Mineralization Comments

Feb 07, 2007 (Mark Puumala) - This occurrence is based on anomalous gold assays reported in Dome Exploration ddh 172-133 (AFRO# 52O08NE0054). The dominant lithology recorded on the drill hole log was intermediate tuff, with some basalt tuff, albite porphyry and massive pyrite. Two gold assays exceeding 1.0 g/t were reported in a section logged as massive pyrite. The mineralized massive pyrite unit was logged across an approximately 7 m wide section and was reported to contain 5% pyrrhotite and 10% quartz/rhyolite. The most significant reported assay was 6.85 g/t Au over 1.0 m.
