Ryoko,
Lots of various forms of circumstantial evidence on what has been found in the drilling is out there.
For example Sao Tome is building a port which it can in no may realistically finance through taxing of its population, since the cost is several times that of the country's GDP. By deduction and process of elimination, it can only achieve the payments on this project from revenues it will collect out of the JDZ. Also ask yourself why such a tiny little nation needs a port the size of 2x its GDP?
Addax, it was discovered on their own website, is hiring some 30+ engineers and managers in the area.
And that's the tip of the iceberg...if you are willing to look, the discovery is not as a big of a secret as you might think it is.
So why isn't ERHC's share price a lot higher than it is now...because it would appear only I-hubbers have linked the circumstantial evidence of having found lots of oil and natural gas with the prosperity of ERHC Energy, AND only I-hubbers are not bound by agreements not to buy shares while possessing this information.
Those who know, who really know what is down there, simply cannot buy as individuals. Now Sinopec on the other hand, might be the only 'entity' who can simultaneously know the results and buy the stock/company, but of course, the flip side is that they will have to pay a premium in exchange for that privilege.
