Description

Promethion mining planets is composed mostly of the rich resource promethion, which can be a very profitable resource. Typically these planets are found further away from its source star and can be mined by building a star base nearby.

Strategy

Typically one would build a star base nearby to this planet type to mine the promethion resource. While building your star base keep in mind there may be other mineable resources around in Thulium Planets, asteroids, or black holes. I would suggest when building your mining star base to encompass as many of these resources as you can to minimize the number of star bases needed.
