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.

NASA has developed and tested this Rotating Detonation Rocket Engine (RDRE).

Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, successfully tested a novel, 3D-printed RDRE for 251 seconds (or longer than four minutes), producing more than 5,800 pounds of thrust.

It is just me, or does that thruster have a nice, old-school starship sci-fi vibe to it? I guess life does imitate art sometimes.
