Do you mean just for the T6? Haha.
i seem to recall, it being way more than that at maxed lair shaping and assuming he can process T6 adamantium at 3:1 and everything else at 4:1. It was well over 60,000 travertine slabs just for one component of the T6 on my GH. I'll get the numbers for you later for max possible best scenario. Pretty sure is in the millions of resources.
