Chelti have a lot of mining ships and ore processing and transport designs. I should write more of them down. Most chelti mining craft have large impact shields on the front, ancillary craft drag unlucky asteroids and comets into the processing areas where they're broken down and transferred by freighter to an ore processing ship which may be some distance away. The processed ore is then put on the barge line back the the starving industry on the home world.4
Gas giants are also tapped for easy fuel and other resources, although more present difficulties. Traditional geological exploitation is done via large mobile platforms assembled by dropship, specific mining methods differ depending on material extracted. Planet cracking is on the table, but currently infeasible.
Mining expeditions are almost always proceeded by scout ships seeding the local system with probes, scanning for life, other occupants, and of course economical viability for mining. Chelti only regard life as "intelligent" if it has invented the radio, this allows them to exploit planets otherwise inhabited by natives; although this policy has led to at least one rather bizarre first encounter regarding a race that completely skipped over radio technology and stuck to wired communication. Very messy. Lots of expensive equipment being broken.
