JTF,
Do you know if they are finding high concentrations of gold and silver that are way above what they originally thought was there?
The forward looking financial statements that I have seen use copper prices of $2.75-$3.50 (currently around $1.60), gold at $500-600, and silver at $10-13.
They also show that copper revenue is expected to be 20 times that of the gold revenue, and about 10x that of the silver revenue. So unless they have hit a motherload of gold, I am not sure how a 20-25% increase in the price of gold is going to offset a 40-50% decrease in the copper prices from their projections.
