DBW, good point. Good drilling results from non Cascabel could just push potential JVers to delete decision to avoid being blamed for putting their money for the "wrong" prize. could be why.
it is a natural feeling to be "upset" when things don't go as one is expecting. it is also natural to have a different investment strategy/expectations i.e. to be looking for a quick return. So no right or wrong thing here.
it makes sense but who knows? From the perspective of a buyer no news helps with expectations management. But, if there is something material, it should be shared by "law/rules".
