TD Securities released a 3-page research note this morning, dealing with SLW's acquisition of Silverstone. They maintain their buy rating and raise the target from $9.00 to $9.50. Below are a couple of excerpts and the summary from the report...

"We interpret this deal as a positive development for Silver Wheaton, in view of the immediate accretion to our earnings estimates and production forecast. The transaction highlights managements focus on acquiring silver stream interests that can promptly enhance the company’s production and cash flow profile, in contrast to a number of prior deals that were weighted towards advanced development and exploration opportunities.
As a result, our NAV5% climbs to $8.10/share (from $7.91) and our 2010 CFPS estimate increases to $0.63/share (from $0.57), thereby raising our 12-month target price to $9.50, from $9.00 previously. We maintain our BUY recommendation."

"As part of its growth mandate, we expect Silver Wheaton to pursue additional silver stream transactions throughout the remainder of this year. We note that the company can tap into a $400mm revolving debt facility to fund acquisitions and based on current metal prices can generate significant operating cash flows to support a substantial draw-down of this facility."

"We interpret the Silverstone transaction as a positive development for Silver Wheaton, based on the immediate accretion to both our earnings estimates and production forecast. As a result, we have raised our 12-month target price to $9.50/share and maintain our BUY recommendation."
