Where the Vrax is it stated Ashura had Six Paths Sage Jutsu?

Six Paths Sage Jutsu is dumb. The Databook entry states they needed it for the "Six Paths: Planetary Construction" but in the flashbacks neither of the two had "Truth Seeking Balls", despite them later having multiple after the conflict.

Maybe Hagoromo sealed the Ten-Tails within himself, then made the seals to seal away the Ten-Tail's body? That's the only explanation I can think of because Six Paths Sage Jutsu should come from the Ten-Tails.

Madara, despite absorbing Sage Chakra from Hashirama, and regaining a Rinnegan, didn't manifest Six Paths Sage Jutsu. So it isn't Six Paths Chakra plus Nature Energy.
