VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 17, 2008) - Silver Wheaton Corp. ("Silver Wheaton") (TSX:SLW)(NYSE:SLW) is pleased to announce that
the early exercise period for two series of its warrants has expired and Silver Wheaton has received gross proceeds in excess of Cdn$120 million. Approximately 87.7% and 91.7% of the issued and outstanding First Warrants and Series A Warrants were exercised early, respectively. The proceeds are expected to be used to pay down debt and fund future growth opportunities.

In connection with the early exercises, Silver Wheaton has issued approximately 2.72 million New Warrants, which will be listed and posted for trading on the Toronto Stock Exchange at the open on September 18, 2008. Each New Warrant entitles the holder to purchase one common share of Silver Wheaton at an exercise price of US$20.00 at any time before 5:00 p.m. (Vancouver time) on September 5, 2013. The New Warrants will trade under the symbol SLW.WT.U and will be traded in US funds.

"The early exercise of warrants provides Silver Wheaton with significant funds, at an attractive cost of capital, for the continued expansion of our portfolio of silver interests," said Peter Barnes, President and Chief Executive Officer of Silver Wheaton. "We are pleased with the outcome as this is an opportune time for Silver Wheaton to strengthen its balance sheet and it positions us well to provide a unique financing solution to traditional mining companies with capital needs."

The First Warrants and the Series A Warrants that were not exercised early remain outstanding and continue to be governed by their current terms. Both series of warrants continue to be listed on the Toronto Stock Exchange under the symbols SLW.WT and SLW.WT.A, respectively.
