Ok T, makes sense. Avik and his goons know how to handle Presilium, but have no experience with it in a lab situation. They know how to deal with it, in containers and out, so Dante calls for them to handle the containers so they can be transported back to the main base (now dubbed Afa-Saryat), where Jason can run his tests on them and do whatever he needs to do. Jason could even possibly be in charge of the labs at the main base, the head of the science department at Afa-Saryat.
Yes, what does Presilium look like? For some odd reason, I keep imagining it to look like a glowing bright green crystal, similar to the color of stereotypical radioactive waste, or Uranium, even though Presilium is a clean resource. I guess when I think future resource, I think Uranium or other glowing green radioactive substances.
