I am in a current, albeit slow-going, discussion (one week now) with the owners in Guate. Mostly, though, with an old friend that knows them. I'll let you know when I know more. I have no investment in this project financially, however. It's just personal.
Initial talk is another permit (I looked that up and can't find a recently denied/pending permit although I may likely have lost the actual issue in translation), but, I do get the impression doing this whole thing from so far away and not having a certain SMU-grad San Martín family member back here to lead the way is a huge set-back.
