The ann does say the delay is due to communication with the UK. Also it is a material raising.
So someone in the UK must want to put in 10s of millions. G24i has managed something like $50m in raisings, some through green funds, they might be looking at us next. Pure speculation of course.
I think we can rule out run of the mill capital raising for on going expenses, they didnt need it yet, something is up, lets hope its good.
