Hi!

A) How dense/heavy is Exuo as compared to earth minerals?

B) Are they mining it themselves or breaking into the mine to find a source of it for themselves? IE left over sacks etc?

C) Just how valuable is it as a tradeable commodity?

D) Related to the others. How much of the exuo are they allowed to claim as their own?

EDIT:

E) Considering there's a physician needed on the trip now, what are the potential dangerous elements to their mission?
