As for Mexico's potential, that is largly dependent on foreign oil companies(hopefully US) developing that potential because Mexico doesn't have the technology or capital to do it.
As for this book, it is just another stoooopid attempt to weave a conspiracy theory so Corsi can sell books and Craig Smith can sell gold to the kooks.
Agreed the general thrust of this statement, but there is another possible value in Gold's perspecive on the genesis of oil from primordial sources, and that is that we might gain some insigts as to where to look. This might very well be marginal, because oil trapping formations would work the same regardless of whether the oil is of geological origin or biobenic origin, but still there might be a discovery or two in there.
