RE: Value
I'm sure it's a lot smaller. On the other hand, area alone doesn't mean a whole lot, look at Deacon's pet gold stock Sirios, they made large land claims in the Opinaca area but that doesn't mean they host any deposits of significance.
Although I suppose in the case of Andean there must have been geological indicators to suggest quite a bit more is there than what has been identified so far, only way $1000 per ounce makes any sense.
