The three games that come to my mind are

>Hardspace: Shipbreaker
>ΔV: Rings of Saturn
>Starsector espescially if you use HMI

Just as >>539219570 pointed out none of them are really /egg/ but Rings of Saturn slightly fits the bill. I would say however that if you haven't played Starsector it does do some of what you're describing & does have mining slightly in the game. However its more focused on the economics, player driven story & combat. Mods are also pretty fucking cool.

Its fucking crazy that sseths review of Starsector has 9.2Mill views. https://www.youtube.com/watch?v=acqpulP1hLo
