Yang Kurama borrowed Chakra from Yin Kurama and it was part of Kaguya when she recharged.
Yin Kurama contributed Chakra to make Nine Tailed Beast Ball Rasenshuriken...Seven of which had the power to obliterate multiple planetoid-like objects and one was used against Kaguya...the last in th clash with Sasuke's Indra arrow, plus the normal Bijuu dama he used...considering the debris from the Chibaku tensei Sasuke diced, just one of those TBBRS should have the energy to destroy a mountain range at minimum.
Did Yang Kurama even use that much energy?
