The drilling this summer will be on the Slide Zone with approximately 1,500 metres to be drilled. This zone was newly discovered in 2006 with intersections in two holes located one kilometre apart, which returned 55.5 metres grading 0.72% copper, 0.07 g/t gold, 5.5 g/t silver and 22.9 metres grading 0.64% copper, 0.15 g/t gold, 30.0 g/t silver.

The most significant copper, gold and silver occurrences on the property all occur within this survey area and include the Upper and Lower Main, Bishop, Ekland, Slide, Boundary, Page and Copper Creek zones.
