• Cash operating margin¹ was US$25.01¹ per silver equivalent ounce, compared to US$34.21 in Q2 2011.
  
  
• Average cash costs¹ fell slightly compared with Q2 2011, to US$4.06¹ per silver equivalent ounce (US$4.04 per ounce of silver and US$303 per ounce of gold).

• Declared quarterly dividend of US$0.10 per common share, representing 20% of the cash generated by operating activities during the three months ended June 30, 2012.
  
  
• Announced attributable proven and probable silver reserves of 798 million ounces, nearly twice the reserves of any other silver company in the world.
  
  
• Subsequent to the second quarter, Silver Wheaton announced that it has agreed to acquire a precious metals stream from Hudbay Minerals Inc.'s ("Hudbay") currently producing flagship 777 Mine ("777"), as well as a silver stream from their cornerstone development project, Constancia. Combined, 777 and Constancia will increase Silver Wheaton's long-term average annual silver equivalent production by approximately 4.9 million ounces².

"For the second quarter in a row, we achieved record silver sales and revenues, putting us on track for our best year ever," said Randy Smallwood, President and Chief Executive Officer of Silver Wheaton. "Production from most of our assets was very solid, with Zinkgruvan once again delivering a strong quarter and with sales of concentrate produced but not yet delivered from Yauliyacu contributing considerably to our revenues and cash flow. While we did see some temporary shortfalls in production at the Peñasquito mine and a delay at Pascua-Lama, we remain confident in our partners and view both of these assets as core streams which solidify our industry-leading growth profile."

"We recently announced a transaction with Hudbay that once again highlights the effectiveness of our business model, combining the certainty of fixed capital and operating costs with immediate cash flow and long term growth potential. We are extremely excited about adding two new streams, one for silver and gold from Hudbay's current flagship mine, 777, and the other for silver from their cornerstone development asset, Constancia. These new streams deliver an immediate increase to our silver and gold production, with 777 contributing average annual production of approximately 4.2 million silver equivalent ounces¹ until the end of 2016. Once Constancia is in full production, which is forecast by 2015, both mines provide substantial opportunity for future growth. With the addition of these assets to our portfolio, our 2016 production guidance has increased to approximately 48 million silver equivalent ounces."

"Furthermore, we remain very excited about the current opportunity-rich environment. With approximately US$600 million in cash - net of the initial US$500 million upfront payment to Hudbay - a fully undrawn US$400 million revolving credit facility, and strong forecast annual operating cash flow, we believe there is substantial opportunity for further growth both in the near and long-term."

Financial Review

Revenues

Revenue was US$201.4 million in the second quarter of 2012, on silver equivalent sales of 6.9 million ounces (6.8 million ounces of silver and 2,400 ounces of gold), a record for the Company. This represents a 3% increase from the US$194.8 million of revenue generated in the second quarter of 2011. This was due to a 36% increase in the number of silver equivalent ounces sold, which was partially offset by a 24% decrease in the realized price per silver equivalent ounce. The increase in silver equivalent ounces sold was primarily related to the timing of shipments of stockpiled concentrate in addition to increased production at some of the mines underlying the Company's silver purchase agreements.

Costs and Expenses

Average cash costs¹ in the second quarter of 2012 were US$4.06¹ per silver equivalent ounce, compared with US$4.14¹ during the comparable period of 2011. This resulted in cash operating margins¹ of US$25.01¹ per silver equivalent ounce, a 27% decrease compared to the second quarter of 2011, primarily a result of a 24% decrease in the realized price per silver equivalent ounce.

During the second quarter of 2012, the Company recorded an income tax expense of US$2.8 million, which includes a non-cash deferred income tax expense of US$2.5 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 compares to an income tax expense of $2.4 million in the comparable period of the previous year, which included a non-cash deferred income tax expense of $2.2 million.

Earnings and Operating Cash Flows

Net earnings in the second quarter of 2012 were US$141.4 million (US$0.40 per share), compared with US$148.1 (US$0.42 per share) for the same period in 2011, a decrease of 5%. Cash flow from operations in the second quarter of 2012 was US$172.9 million (US$0.49 per share¹), compared with US$168.3 million (US$0.48 per share¹) for the same period in 2011, an increase of 3%. The change in net earnings and operating cash flows is primarily due to a 36% increase in the number of silver equivalent ounces sold, which was partially offset by a 24% decrease in the realized price per silver equivalent ounce.

Balance Sheet

At June 30, 2012, the Company had approximately US$1.1 billion of cash on hand. In addition, the Company had US$400 million of available credit under its revolving bank debt facility. Following the initial US$500 million upfront payment due to Hudbay under the recently announced transaction, 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 (6.5 million ounces of silver and 3,200 ounces of gold) in the second quarter of 2012, representing an increase of 10% compared to the second quarter of 2011.

Operational highlights for the quarter ended June 30, 2012 are as follows:

Peñasquito -

While attributable silver production increased 42% compared to 2011, to over 1.8 million ounces, as per Goldcorp Inc.'s ("Goldcorp") July 10, 2012 disclosure, second quarter mill throughput at its Peñasquito mine was impacted by lower than anticipated water supplies, the result of prolonged drought conditions in the region. The water deficit is expected to limit plant throughput to between approximately 98,000 and 107,000 tonnes per day over the balance of 2012, resulting in a reduction of forecast silver production attributable to Silver Wheaton during this period.

Goldcorp holds permits for sufficient quantities of water and is currently working to drill additional wells to increase water production. Concurrently, work is also underway to increase the quantity of water reclaimed from the tailings facility.�  Goldcorp highlighted that both the processing plant and the ore body continue to perform well, and the focus now is on bringing water wells into production. � Peñasquito will become Silver Wheaton's largest contributor of silver production in 2012, with forecast attributable silver production of approximately 7 million ounces once at full design capacity.

Pascua-Lama -

As per Barrick Gold Corporation's ("Barrick") second quarter 2012 MD&A, initial production at their world-class gold-silver Pascua-Lama project has been delayed due to lower than expected productivity. Initial production, previously expected in mid-2013, is now expected in mid-2014, with an approximate 50 to 60 percent increase in capital costs from the top end of its previously announced estimate of $4.7 to $5.0 billion. During the second quarter, the project achieved critical milestones with completion of Phase 1 of the pioneering road and also the water management system in Chile, both of which enabled the commencement of pre-stripping activities.

Until December 31, 2015, Silver Wheaton will be entitled to all or a portion of the silver production from Barrick's Veladero, Pierina and Lagunas Norte mines, to the extent Pascua-Lama is operating below 75% of design capacity. 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.

Zinkgruvan -

Silver Wheaton's second quarter 2012 attributable silver production from the Zingruvan mine was a record 673,000 ounces, an increase of 63% compared to the second quarter of 2011. As per Lundin Mining Corporation's July 25, 2012 disclosure, metal production year-to-date is at all time highs due to high ore grades, good recoveries and record throughput levels.

Produced But Not Yet Delivered -

Payable silver equivalent ounces produced but not yet delivered to Silver Wheaton by its partners fell by almost one million ounces to approximately 3.2 million silver equivalent payable ounces at June 30, 2012. The reduction was primarily due to the sale of a substantial portion of the stockpiled concentrates at Glencore International AG's Yauliyacu mine.

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.

On April 24, 2012, the British Columbia Securities Commission ("BCSC") issued a notice of hearing� naming as respondents Canaco Resources Inc. ("Canaco") and certain of its directors. Mr. Randy Smallwood, President and CEO of Silver Wheaton, was previously a non-executive director of Canaco, and is named in the notice of hearing. The BCSC alleges that, in December 2010,� Canaco failed to file a material change report when it received certain drill results, and, further, that its Board voted to price directors' options prior to disclosure of the drill results. The BCSC alleges that by�  delaying the disclosure, the Canaco directors were able to set the exercise price of the options lower than would have been the case if Canaco had promptly disclosed the drill results.

The Board of Silver Wheaton has, together with legal counsel to the Board, examined the allegations against Mr. Smallwood and considered the implications to the Company. The Board does not believe that this matter will adversely affect Mr. Smallwood's ability to perform his role as the Company's President and CEO.�  Furthermore, the Board has been advised that Mr. Smallwood has a legitimate defence to these unproven allegations, which he intends to vigorously defend.�  In light of the foregoing, and given the Board's confidence in Mr. Smallwood, they continue to� be� fully and completely supportive of him in his role as President and CEO of Silver Wheaton.
