Lots of changes to mining and asteroids.
There is now just one "metal" resource that is mined from asteroids rather than the previous Common, Reactive, Radioactive and Rare metals that have been in the game until now. This is to reduce the orders micromanagement for mining ships. Now there is no need to constantly keep track of what they are mining and balance the amounts of each resource you need.
To keep some complexity there are now a lot more asteroid minerals, each having a different maximum yield and mining multiplier (accessibility). Yield is the maximum amount you can mine from the asteroid and the mining multiplier affects mining laser module speed.
Rare asteroid minerals will be faster to mine and take longer until they become depleted, but every mineral type still provides the same "metal" resource used for building stuff.
During galaxy generation there will be an option to re-spawn asteroids some time after they have been mined completely. When an asteroid re-spawns it will return as the next smaller size (Large becomes a Medium etc.)
Larger asteroids have much higher yield and mining multipliers. This is to discourage mining in the same asteroid belt forever if you are going to use the re-spawn option. It will still be better to look for larger asteroids.
Asteroid stats example:
Large: Yield = 2400, Multiplier = 140%
Medium: Yield = 1200, Multiplier = 120%
Small: Yield = 600, Multiplier = 100%
Depleted: Yield = 300, Multiplier = 80%
Listed below are the asteroid minerals currently in the game. I decided to use real mineral names found on Earth rather than made up ones. Not sure if this would be realistic as I expect there are some minerals below that wouldn't be found on asteroids. (let me know of any)
The element composition of each mineral shown on the tool-tips have no effect on gameplay, just something interesting I wanted to add.
Common Minerals: Sphalerite, Chalcopyrite, Pyromorphite, Cuprite, Stibnite, Kamacite, Acuminite and Pyrolusite.
Uncommon Minerals: Chromite, Boehmite, Wolframite, Cobaltite, Faustite, Rutile and Barite
Semi-Rare Minerals: Ruthenium, Molybdenite, Polarite, Thorite, Rhodium, Iridium and Gold
Rare Minerals: Rhenium, Bromellite, Palladium, Osmium, Gadolinite, Monazite, Churchite and Sylvanite.
Asteroid details will be shown on discovered planet tooltips.
