If you can ship it there from the moon in a 5T craft, and return the craft to the moon, it costs 171 T of fuel.

Much more interestingly, the same SSTO can now take 40T to LEO instead of 10 with little more total fuel cost. The fuel per tonne to LEO drops 72%.
In honor of truth, with the increasing ISP values the amount of landing fuel you need will decrease, becoming additional useful payload.
I didn't account for that not to make it too complicated but with an increase of ISP to 410 the return fuel would roughly decrease from 30 to 25 Tons.
