There's a difference between getting the seismic back and having something to release.
It takes a long time to get a meaningful interpretation out of seismic. It may not have even worked at delineating pegmatites.
I'm personally surprised they went this route. I would have thought there is too small a density contrast and too thin units for it to work.
But yeh. I suspect as well that results are in but they are sitting with a 3rd party and going back and forth with interpretations.

There has also been little info on what they did. Conventional? 2D? 3D? Or just passive seismic? Concentional seismic is expensive and generally targets far too deep for what's useful at this project.
