PTV & PTA Farm InI suspect PTV had the right to refuse the farm in. If the discovery is as good as it looks, it makes sense they (PTV) would not want PTA to take half their interest for 2.5m of expense coverage - See the following from a PTA press release:
In order to farm-in to the Morochito interest, the Company is required to pay Petro Vista's cost of a planned well (to a maximum of US$2.5 million)
This isn't a problem for PTA - They already own 28% of PTV and have the right (via warrants) to acquire up to 44% at a cost of 30 cents per share.
So the company they made an investment in doesn't need thier money. That is good. Sure they don't get the 25% interest in Morochito, but they can exercise thier warrants (price is almost there) and obtain a much larger piece of the entire company at a bargain basement cost.
They'll be close to controlling PTV when they exercise. This is a huge win. And more news on PTV and PTA comind down the pipe.
Have faith in this management. They know what they are doing. Perhaps look for them to exercise their warrants before too long on PTV.
