It is all mind boggling, no doubt!
Also, not to discredit what you're saying Sculpin, but more to add to it, but the Anomally is much bigger than a KM squared, according to the Comapny News Releases, anyway.
It is actually just over 3KM squared, and just shy of a volume of 4 Billion M3 (and open to depth)
Once again from the Mining stock Report (some discredit this, some believe this, to each their own):
Tesoro contains large deep anomalies up to several billion cubic meters in size with high (mostly gold) sulfide content (>1%)
Not sure who this poster is, but they provided a link that day on Agoracom:
