It would make no sense for Goldcorp to ever say it was in the market to takeover companies. Especially not specific ones. Why raise the price on something you will be bidding for? It would also make perfect sense that, given the location of both Rubicon and Sangold, Goldcorp knows exactly what both of these companies have got, and have routinely thought about whether acquisition was feasible or desireable.
Personally, I'd like to see our company turn a tidy profit and double in value before Goldcorp gets serious.
