Jun 22, 2010, 18:44 ET from Silver Wheaton Corp.



VANCOUVER, June 22 /PRNewswire-FirstCall/ - Silver Wheaton Corp. ("Silver Wheaton") (TSX, NYSE: SLW) is pleased to announce that, as reported by Goldcorp Inc. ("Goldcorp") in a press release dated June 22, 2010, the second sulphide processing line (Line 2) at Goldcorp's world-class gold-silver-lead-zinc Penasquito mine in Zacatecas, Mexico, has achieved mechanical completion ahead of its previously expected third quarter completion date.

Over life of mine, Penasquito is forecast to produce an average of approximately 28 million ounces of silver annually over an initial 22 year mine life, of which Silver Wheaton is to receive 25% or approximately seven million ounces of silver annually.

Penasquito's Line 1 is regularly operating at a designed daily throughput of 50,000 tonnes, and Line 2 is now in the commissioning phase and ramping up to add another 50,000 tonnes per day of capacity. In the first days of commissioning and ramp-up of Line 2, combined process plant throughput already reached in excess of 86,400 tonnes per day. Line 2 alone has reached peak daily throughput of over 52,000 tonnes. In addition, the project's concentrate grades and quality remain well within expectations.

Construction of the project's 30,000 tonnes per day high pressure grinding roll circuit is also on track for completion in the fourth quarter, and Penasquito's full production ramp-up to designed 130,000 tonnes per day capacity remains on track for early 2011.

"We remain extremely pleased with the impressive construction and ramp up progress at Penasquito, Silver Wheaton's cornerstone growth asset for the next several years," said Peter Barnes, Chief Executive Officer of Silver Wheaton. "With full mine production forecast for early 2011, our stakeholders continue to recognize significant value from Penasquito, the second largest silver deposit in the world and soon to be Mexico's largest mine."
