I need help finding a mod

I remember a mod where there we're a bunch of new ores, and there are these things I'll call "Ore Temples". It's a small place made of a certain ore, and there is an "ore stick" in a chest in the temple. Also, the copper is blue. That's something I can remember. Oh yeah! There are also these weird things, and when you break them an ore comes out, and there on the grass near a potential cave, I believe. I need help finding this mod, as I haven't remembered the name of the mod. Does anybody know it, or have any leads? (PS: I got this on 9minecraft.net, so it has to be on there with a version 1.12.2 in its roster)
