From Resource Investor:
Silver Wheaton Corp. [NYSE:SLW] has signed a binding letter agreement to purchase between 45% and 90% of the life-of-mine silver to be produced by the Rosemont Copper Project, 100%-owned by Augusta Resource Corporation [AMEX:AZC; TSX:AZC].
Silver Wheaton will pay an upfront cash payment ranging in value from US$135 million to US$165 million to acquire 45% of the payable silver, or US$240 million to US$320 million to acquire 90% of the payable silver, produced for the life-of-mine.
The Rosemont Project is a copper-molybdenum-silver-gold porphyry deposit located in Pima County, Arizona. Based on a positive Feasibility Study released in August 2007, the Rosemont mine is expected to produce annually an average of 220 million pounds of copper, 4.5 million pounds of molybdenum, 2.7 million ounces of silver and 15,000 ounces of gold over the mine life, currently expected to be a minimum of 18 years.
Update: More on the deal:
This would indicate a cost for Silver Wheaton of between US$5.50 and $7.50 per ounce over 18 years depending on the final terms, compared with a current silver spot price of about $14 an ounce.
Augusta CEO Gil Clausen said the Silver Wheaton financing will cover 16 to 38 per cent of the project’s expected capital cost in return for only two to five per cent of total projected revenue.
For Silver Wheaton, the transaction “provides long-term growth potential … without project permitting or financing risk,” stated Silver Wheaton CEO Peter Barnes, adding that it provides “maximum upside to the silver price, and also eliminates the major operating risk in the industry today, being increasing operating and capital costs.”
