Agreed, DD is indeed very important. And part of the DD done on this forum in the past, was ascertaining that the properties were real, just as a security measure for investors. This was accomplished through satelite images among other verification methods. The most recent satelite images we have of the Tesoro, suggests advancement along the mining aspect side of things.

Although there was undoubtedly playing with the stock price involved with this fiasco, imo, that looks to be only a part of what may be a much more complex picture.
