SILVER WHEATON APPOINTS SENIOR VICE PRESIDENT, CORPORATE DEVELOPMENT, TO LEAD COMPANY’S GROWTH INITIATIVES

Vancouver, British Columbia – Silver Wheaton Corp. (“Silver Wheaton” or the “Company”) (TSX:SLW)(NYSE:SLW) is pleased to announce the appointment of Mr. Haytham Hodaly as Senior Vice President, Corporate Development, effective January 1, 2012. By identifying and establishing promising new silver streaming partners, and further strengthening the company’s current partnerships, Mr. Hodaly will play a key role in ensuring Silver Wheaton achieves its strategic growth initiatives.

Mr. Hodaly brings with him over 16 years of experience in the North American securities industry, most recently as Director and Mining Analyst, Global Mining Research, at RBC Capital Markets. In this role, he was responsible for providing, to a wide range of institutional clients around the globe, up-to-date and insightful research coverage of North American-listed precious metals companies. Prior to this, he held the position of Co-Director of Research and Senior Mining Analyst at Salman Partners Inc., in addition to holding the titles of Vice President and Director of the firm. During his tenure, Mr. Hodaly helped grow the organization from eight to over 50 industry professionals, and establish Salman Partners Inc. as a leading independent, resource-focused and research-driven investment dealer. In addition to offering high-quality mining research to the firm’s extensive institutional client base, he was also an invaluable source of corporate development ideas for Salman Partners’ investment banking group. Mr. Hodaly is an engineer with a B.A.Sc. in Mining and Mineral Processing Engineering and a Masters of Engineering, specializing in Mineral Economics.

“We are pleased to have someone of Haytham’s calibre join our talented team of corporate development professionals,” said Randy Smallwood, Silver Wheaton’s President and Chief Executive Officer. “As a highly regarded mining analyst with extensive resource-based experience, Haytham has in-depth knowledge of a large number of mining projects around the world. This, along with his key industry relationships, will further enable Silver Wheaton to achieve its goal of acquiring additional high-quality silver streams and to grow its world-class portfolio of assets.”

Silver Wheaton is also pleased to announce that Mr. Neil Burns, currently Silver Wheaton’s Director of Geology, will assume the role of Vice President, Technical Services, effective January 1, 2012. In his new role, Mr. Burns will manage a team of geological and mining engineering professionals, and will be responsible for all technical matters relating to corporate development opportunities and to Silver Wheaton’s current streaming agreements.
