At a 0.3% cut-off, measured resources are 38 million pounds of copper and 7,200 ounces of gold and indicated resources are 1,176 million pounds and 279,700 ounces respectively. Total measured and indicated resources are 1.22 billion pounds of copper and 287,000 ounces of gold and inferred resources are 776 million pounds and 209,000 ounces respectively. The resource increase represents both the upgrading of inferred resources and the addition of new resources. Inferred resources are now 37% of total resources versus 87% previously.
