SILVER WHEATON ANNOUNCES GOLDCORP’S PEÑASQUITO MINE COMPLETES
CONSTRUCTION OF SECOND PROCESSING LINE AHEAD OF SCHEDULE
Vancouver, British Columbia – 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 Peñasquito mine in Zacatecas,
Mexico, has achieved mechanical completion ahead of its previously expected third quarter completion date.
Over life of mine, Peñasquito 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.
Peñasquito'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 Peñasquito’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 Peñasquito, 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 Peñasquito, the second largest silver deposit in the world and soon to be Mexico’s larg
