VANCOUVER, April 12, 2011 /PRNewswire-FirstCall/ -- Silver Wheaton Corp. ("Silver Wheaton" or the "Company") (TSX: SLW) (NYSE: SLW) is pleased to announce that Randy Smallwood, currently the Company's President, has been appointed Chief Executive Officer. He will replace Peter Barnes, who has resigned effective April 11, 2011. As part of the transition process, Mr. Barnes has agreed to enter into a consulting agreement with Silver Wheaton.

"I am very proud to have been a part of a team that, in just over six years, successfully built one of the largest silver companies in the world," said Peter Barnes. "Silver Wheaton is exceptionally well-positioned to continue its strong tradition of creating shareholder value, and I have decided that it is the right time for me to step aside as Chief Executive Officer. I have worked very closely with Randy for the last eight years, am confident in his abilities, and I would like to wish him and the Silver Wheaton team all the best as the Company transitions to its next phase of growth."

"Since the inception of Silver Wheaton in 2004, the Company's shareholders have benefited greatly from Peter Barnes' dedication, focus and commitment," said Doug Holtby, Chairman of Silver Wheaton. "Under Peter's leadership and with the support of his team, the Company has become one of the most profitable precious metals companies in the world, and this will be his legacy. We wish him great success in his future endeavours. The Board would also like to congratulate Randy Smallwood on his appointment as President and Chief Executive Officer. We are certain that the Company will continue to be a market leader under his guidance."

Randy Smallwood holds a geological engineering degree from the University of British Columbia, and is a founding member of Silver Wheaton. He was an instrumental part of the team that built Wheaton River/Goldcorp into one of the largest and most profitable gold companies in the world, and in 2007 he joined Silver Wheaton full time as Executive Vice President of Corporate Development, primarily focusing on growing the Company through the evaluation and acquisition of silver stream opportunities. In recognition of his significant contribution to Silver Wheaton's pre-eminent position as market leader in its sector, Randy was appointed Silver Wheaton's President in January 2010.

"I am excited to take on the role of Chief Executive Officer, and to continue working with this exceptional management team, a team which has contributed to building Silver Wheaton's industry-leading production growth profile and has created one of the largest silver companies in the world," said Randy Smallwood. "We remain committed to positioning Silver Wheaton as the go-to investment vehicle for those looking for exposure to an increasing silver price, and we look forward to capitalizing on the many silver streaming opportunities that lie ahead. Finally, I would like to take this opportunity to thank Peter Barnes for his great leadership and mentorship over the years, and to wish him continued success in the future."
