Mineralization Comments

Aug 19, 2010 (A Pace) - The visible mineralization consists of massive to disseminated pyrite with a brecciated and recrystallized banded chert which is probably a brecciated sulphide iron formation. The unit strikes a approximately N50W, dips 80N and . The unit is approximately 1 m thick and was traced for about 200 m to the northwest. A grab sample collected was assayed and indicates 0.12% copper, 0.01% Lead, 0.02 ounce per ton gold and trace silver. Grab samples collected by Noranda Exploration Ltd., consisting of chert-hosted massive to semi-massive pyrite-pyrrhotite returned up to 0.15% Zn with negligible Cu-Pb-Ag values.
