Goldcorp's strategy is mainly North and South America, which would seem to favor AUY and DEZ. Of course it is pure speculation on my part, but I doubt goldcorp is looking to expand in Brazil because they already have a presence there with Amapari. Brazil's currency is strong right now, which tends to be negative towards gold mining. If AUY had a silver bonus, it might be different. Chapada does have a copper play, though, which fits the Wheatie strategy.
I expect a US or Australian acquisition to replace aging Wharf and Peak mines. Mexico seems to be a longshot from a diversity standpoint. There are three Mexico properties: San Martin, San Dimas, Los Filos. However, as JC points out, goldcorp might see El Limon as such a strategic play that it cannot be ignored, diversity be damned. I would not rule out a stronger Canadian presence either, esp. in conjuction with Red Lake.
