Thanks, Zen, That is exactly how I thought it went back then. I digged a little deeper and for those who are interested, here is the story:

Back in 2004, IAMGold and Coeur d'Alene were both interested to buy Wheaton River Minerals (WRM), a company with projects in Australia, Mexico and Argentina. Mr. Ian Telfer, chairman and CEO of WRM, aware of the interest, realized that the company did not have a fair "precious metal valuation", due to its exposure to copper from the Alumbrera project in Argentina.

To create a higher share valuation, they decided to sell 100% of the future silver production from the Luismin project in Mexico to Silver Wheaton (back then Chapman Mercantile), in exchange for SLW shares.

In October 2004 this transaction was finalized. A second silver stream transaction, with Lundin Mining for the silver production of their Zinkgruvan project in Sweden was signed in November 2004. In April 2005 Goldcorp bought Wheaton River Minerals for $2B, 10% more than Coeur d'Alene offered a year before. On April 20, 2006, Peter Barnes the CFO of Silver Wheaton became President and CEO, while the same day Nolan Watson, controller, took Mr. Barnes position as CFO. David Awram was Manager Investor Relations at that time.
