The market thinks the Barrick contract will cost SLW 1 billion here. If you disagree with the market then yes, this is a buying opportunity. It will take a few days for the analysts to go over the contracts and the funds to sort out their positions. It could be a great buy, but it requires you to take the risk of catching the analysts off guard. Easier to just buy it and short the silver portion out and let it settle out. The discount to their stream here is significant, meaning that this is all due to the mis-pricing of the Barrick news.
