The MineralMod is in 1.15->1.15.2 and adds a lot of new ores that can be used to make alloys for even more powerful ores.
The mod is currently in V1 and only adds ores in the overworld.
see the patch notes of the new versions if you want more information
The ores to be extracted:
opale: used to craft weak but very powerful tools, armor and weapons;
lithium: used to make alloys;
aluminum: takes a long time to cook, is used to make aluminum bars to make alloys;
Platinum: is extremely rare, is used to make platinum powder (5 per ingot) which is used to make alloys.
Alloys:
steel: made of 9 blocks of iron, used to make very strong armor, very strong but not very powerful tools and weapons, and a block as strong as obsidian;
alidium: made with 1 lithium block and 8 aluminum bars, used to make strong and powerful tools, weapons and armor;
the super diamond: made with 1 diamond and 8 diamond blocks, used to make very strong and powerful armor, tools and weapons;
pink europium: a platinum powder, 2 lithium ingots and 6 super diamonds to have 3 ingots, used to make extremely powerful and extremely resistant tools, weapons and armor;
white europium: craft with 1 opale block, 2 steel ingots, 2 super diamonds and 4 lithium ingots; used to craft the second most powerful and durable tools, armor, and weapons in the mod;
green europium: composed of 3 blocks of alidium and 6 super diamonds, used to craft the most powerful tools, weapons and armor in the mod.
