Nanofabrication eliminates the necessity (though not the convenience) of harvesting complex chemistry whole. The hungry cornucopia machines may require only raw elements, but they require it in abundance. Survite nanoswarms help make it possible for transhumanity to survive on scattered dead rocks.
Set a hive on the ground and leave it to cook. Survites will filter through regolith and rock, relaying their findings up the chain, back to the hive. The longer the hive works, the farther it can spread its network, building comprehensive geological maps. Survites and survite hives are one of the most popular pieces of nanotech in the system, used by Consortium mining concerns and Brinker prospectors alike.
