The investment group responsible for the two high orbiting settlements had been selecting a few more useful source asteroids for robotically refining, preparing, and sending out more special future loads. Then when their original chosen metal-rich (M-type) source asteroid would be orbiting on the opposite side of Sol from something being constructed, another such asteroid might likely be much closer, thus quicker to send wanted prepared loads from.
They also selected a few source asteroids of C-type (carbonaceous, 3/4 of asteroids) and S-type (silicate-rich with some metals, 1/6 of asteroids). (Metal-rich M-type were 1/10 of asteroids.) 100-200km size should be ok. They thus got a few such useful ones between Earth and Mars also registered to be for their future robotic use.
If of density 3g/cc (Luna is 3.341), then escape velocities to toss loads out from 100km or 200km asteroids would be not too awfully fast 65m/s or 130m/s (145mph or 290mph), (about like spanning a sports field park in a second).
Different ways had been considered to achieve such escape velocities. Easiest was to anchor a strong tower deep into some convenient high point. At the top of the tower fix a very strong vertical axis motor having a big slow turning inverted "L" top.
Hang any prepared load from a mostly reeled up cable out at the high horizontal arm's end. Slowly swing a cable attached load around. As it swings out horizontal, let more cable length get safely pulled unreeled. The long length of the top side arm keeps getting the lengthening cable turning ok.
Such a 3g/cc 100km or 200km asteroid would have surface gravity .0419m/s^2 or .0839m/s^2 (only .424% or .848% of Earth surface gravity g, /s^2 means per second squared). When such a load is 100m or 200m out, easily spinning once in 9s, this exceeds the asteroid's escape velocity, to be released to easily fly away. Away from the asteroid, have ion jets used to adjust where it will go.
