We'll probably find out from a flashback or some dialogue from either Shino or Mitsuki.

"Yo Naruto, Orochimaru's son has Sage Mode" Well Orochimaru and Hiruzen too produced Chakra cloak in their fight in part-1. I thought it was just him releasing his chakra like Tobirama or Hashirama. I could be wrong though.
