Silver Wheaton Reports a Strong Start to 2012 with Record Quarterly Revenues of US$200 Million06:30 EDT Monday, May 14, 2012 TSX: SLW NYSE: SLW VANCOUVER, May 14, 2012 /PRNewswire/ - Silver Wheaton Corp. ("Silver Wheaton" or the "Company") (TSX:SLW)(NYSE:SLW) is pleased to announce its unaudited results for the first quarter ended March 31, 2012. FIRST QUARTER HIGHLIGHTS Attributable silver equivalent production of 6.7 million ounces (6.6 million ounces of silver and 2,100 ounces of gold), an increase of 8% compared with Q1 2011. Revenues increased 26% compared with Q1 2011, to a record US$199.6 million, on record silver equivalent sales of 6.1 million ounces (5.9 million ounces of silver and 3,900 ounces of gold). Net earnings increased 20% compared with Q1 2011, to US$147.2 million (US$0.42 per share). Operating cash flows increased 29% compared with Q1 2011, to US$163.8 million (US$0.46 per share1). Cash operating margin1 increased slightly compared with Q1 2011, to US$28.51 per silver equivalent ounce, amongst the highest in the sector. Average cash costs of US$4.081 per silver equivalent ounce (US$4.02 per ounce of silver and US$303 per ounce of gold), relatively unchanged from Q1 2011. Cash balance of US$997.5 million, with a net cash position of US$926.0 million at the end of Q1 2012. Declared quarterly dividend of US$0.09 per common share, representing 20% of the cash generated by operating activities during the three months ended December 31, 2011. Announced attributable proven and probable silver reserves of 798 million ounces, nearly twice the reserves of any other silver company in the world. "Solid operating performance from across our portfolio of mines led to a strong start in 2012," said Randy Smallwood, President and Chief Executive Officer of Silver Wheaton. "We achieved record quarterly revenues, and are on target to attaining our annual production guidance of 27 million silver equivalent ounces. With continued positive progress at our world-class cornerstone assets, including the Peñasquito and Pascua-Lama mines, Silver Wheaton retains one of the strongest growth profiles in the sector." "While there continues to be a strong trend of expanding capital needs in the mining industry, challenging global financial markets have made access to traditional forms of capital, such as debt and equity, much more difficult. In this environment, Silver Wheaton's streaming model offers a particularly attractive funding solution for mining companies, and we continue pursuing value-enhancing acquisitions. With approximately US$1 billion in cash on hand, a fully undrawn $400 million revolving credit facility, and forecast annual operating cash flows in excess of $600 million at current precious metals prices, Silver Wheaton is exceptionally well-positioned to grow its portfolio of high-quality precious metals streams, further boosting its long-term production levels." Financial Review Revenues Revenue was US$199.6 million in the first quarter of 2012, on silver equivalent sales of 6.1 million ounces (5.9 million ounces of silver and 3,900 ounces of gold), a record for the Company. This represents a 26% increase from the US$158.2 million of revenue generated in the first quarter of 2011, due to a 25% increase in the number of silver equivalent ounces sold. Increased sales were primarily related to the timing of shipments of stockpiled concentrate and to increased production at some of the mines underlying the Company's silver purchase agreements. Costs and Expenses Average cash costs in the first quarter of 2012 were US$4.081 per silver equivalent ounce, compared with US$4.071 during the comparable period of 2011. This resulted in cash operating margins1 of US$28.51 per silver equivalent ounce, a slight increase compared to the first quarter of 2011. During the first quarter of 2012, the Company recorded an income tax expense of US$3.3 million, which includes a non-cash deferred income tax expense of US$3.1 million, attributable primarily to the reversal of previously recognized deferred income tax assets relating to the decline in fair value of long-term investments in common shares and to income from Canadian operations. This compared to an income tax recovery of $2.3 million in the comparable period of the previous year, which included a non-cash deferred income tax recovery of $2.5 million. Earnings and Operating Cash Flows Net earnings in the first quarter of 2012 were US$147.2 million (US$0.42 per share), compared with US$122.2 (US$0.35 per share) for the same period in 2011, an increase of 20%. Cash flow from operations in the first quarter of 2012 was US$163.8 million (US$0.46 per share1), compared with US$127.2 million (US$0.36 per share1) for the same period in 2011, an increase of 29% (an increase of 28% on a per share basis). The increase in net earnings and operating cash flows is primarily attributable to a 25% increase in the number of silver equivalent ounces sold. Balance Sheet At March 31, 2012, the Company had approximately US$997 million of cash on hand. In addition, the Company had US$400 million of available credit under its revolving bank debt facility. The combination of cash, available credit, and strong operating cash flows, positions the Company well to execute on its growth strategy of acquiring additional accretive silver stream interests. Operational Highlights Attributable silver equivalent production was 6.7 million ounces (6.6 million ounces of silver and 2,100 ounces of gold) in the first quarter of 2012, representing an increase of 8% compared to the first quarter of 2011. Operational highlights for the quarter ended March 31, 2012 are as follows: Peñasquito - As stated in Goldcorp Inc.'s ("Goldcorp") press release dated March 28, 2012, the high pressure grinding roll supplemental feed system at the Peñasquito mine was successfully commissioned during the first quarter of 2012. Throughput in the last three weeks of March 2012 averaged over 110,000 tonnes per day, and included record daily throughput of 143,000 tonnes on March 13, 2012. In the ten days prior to mid-April, throughput averaged 123,000 tonnes per day. Activities at Peñasquito over the balance of 2012 will focus on further optimization of the processing line. Peñasquito will become Silver Wheaton's largest contributor of silver production in 2012, with forecast attributable silver production of approximately 7 million ounces. Pascua-Lama - As stated by Barrick Gold Corporation in its first quarter 2012 MD&A, the Pascua-Lama project remains on track to commence production in mid-2013, with over 70% of the previously announced pre-production capital budget of $4.7 to $5.0 billion committed.  At the end of the first quarter, earthworks in Chile and Argentina were approximately 97% and 73% complete, respectively, with pre-stripping expected to commence during the second quarter. Once in production, Pascua-Lama is forecast to be one of the largest and lowest cost gold mines in the world with an expected mine life in excess of 25 years. In its first full five years of operation, Silver Wheaton's attributable silver production is expected to average nine million ounces annually. San Dimas - As per Primero Mining Corp.'s ("Primero") March 28, 2012 disclosure, in an effort to improve mine planning and expand long-term production levels at its San Dimas mine, Primero elected to utilize block modeling to estimate its mineral reserves and resources rather than the polygonal method, which it had used historically. The estimates made using this new approach resulted in a reduction in both silver reserves and inferred resources at the San Dimas mine, as of December 31, 2011. Primero's disclosure also states that there is significant exploration potential at San Dimas beyond the stated mineral reserves and resources, some of which has been reported as mineral potential. Further details can be found in their March 28, 2012 disclosure. Primero believes that the new estimation approach will improve mine planning, and that further drilling and mine development will result in mineral resources being converted to mineral reserves, a reasonable amount of the exploration potential being converted to inferred resources, and new mineral discoveries being realized. Produced But Not Yet Delivered - Payable silver equivalent ounces produced but not yet delivered to Silver Wheaton by its partners was virtually unchanged in the first quarter, with a total of approximately 4.2 million payable ounces at March 31, 2012. The total is primarily attributable to Glencore International AG's Yauliyacu mine, and Goldcorp's Penasquito mine, where approximately 1.7 million and 1.3 million ounces of cumulative payable silver ounces have been produced but not yet delivered to the Company, respectively. Detailed mine by mine production and sales figures can be found in the Appendix of this press release and in Silver Wheaton's Management's Discussion and Analysis ("MD&A") in the 'Results of Operations and Operational Review' section. This earnings release should be read in conjunction with Silver Wheaton's MD&A and unaudited Financial Statements, which are available on the Company's website at www.silverwheaton.com and have been posted on SEDAR at www.sedar.com. ----------------------------------------- 1 Please refer to non-IFRS measures at the end of this press release.

Non-IFRS Measures Silver Wheaton has included, throughout this document, certain non-IFRS performance measures, including (i) average cash costs of silver and gold on a per ounce basis; (ii) operating cash flows per share (basic and diluted); and (iii) cash operating margin. i.      Average cash cost of silver and gold on a per ounce basis is calculated by dividing the total cost of sales, less depletion, by the ounces sold. In the precious metals mining industry, this is a common performance measure but does not have any standardized meaning. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's performance and ability to generate cash flow. ii.      Operating cash flow per share (basic and diluted) is calculated by dividing cash generated by operating activities by the weighted average number of shares outstanding (basic and diluted).  The Company presents operating cash flow per share as it believes that certain investors use this information to evaluate the Company's performance in comparison to other companies in the precious metals mining industry who present results on a similar basis. iii.      Cash operating margin is calculated by subtracting the average cash cost of silver and gold on a per ounce basis from the average realized selling price of silver and gold on a per ounce basis. The Company presents cash operating margin as it believes that certain investors use this information to evaluate the Company's performance in comparison to other companies in the precious metals mining industry who present results on a similar basis. These non-IFRS measures do not have any standardized meaning prescribed by IFRS, and other companies may calculate these measures differently. The presentation of these non-IFRS measures is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.  For more detailed information, please refer to pages 14 to 16 of Silver Wheaton's Management Discussion and Analysis available on the Company's website at www.silverwheaton.com and posted on SEDAR at www.sedar.com.     SOURCE Silver Wheaton Corp.For further information: <p> Brad Kopp <br/> Senior Vice President, Investor Relations<br/> Silver Wheaton Corp.<br/> Tel: 1-800-380-8687<br/> Email: <a href="mailto:info@silverwheaton.com">info@silverwheaton.com</a><br/> Website: <a href="http://www.silverwheaton.com">www.silverwheaton.com</a> </p>
