- You cannot remote mine colonized worlds.
- By default, remote miners reduce the value of the worlds being mined by 1% per turn.

It is possible to colonize, build a value improvement plant, wait a few years, then abandon and remote mine, but you'll be doing a lot of work and wait a very long time for not much return.
Heavily modded, you could get a situation where you remote mine for a decade, colonize and value improve +100% for a year, then abandon and remote mine again.
