Can you imagine the lawsuits from stockholders who sold at 30 cents if Zion Oil knew they had a major oil strike and withheld that information from investors? It isn't happening, and it's not going to happen.
It's an argument presented for every "well" Zion Oil has ever drilled, and it always ends the same.
But I do disagree on one point - they are under no obligation to say anything at all if the well is drilled to the depth, and it turns out to be a dud. Their only requirement is to write off in drilling expense in the next quarterly or annual report. A simple statement in the quarterly report - we drilled to depth and found nothing economical - is all, if even that, they need.
Twenty years ago, the former ISRAMCO Inc (not the partnership, the stock) drilled a well in the Congo. When they finished, they closed up the well and left. Nothing was said, no press releases were ever issued after the initial one that they spud in the Congo. The only thing investors got out of them was an entry in their annual report indicating the money was spent. I assume that was legal. Zion Oil could do the same.
