New Ores, Tools, and Armor

I think there should be new ores coming in this update. I mean it has caves in the name. In these caves we can have new different ores like ruby, sapphire, platinum, etc. With these new ores, we can make new armor and tools. These could also be used to craft exclusive tools/weapons like hammers, katanas, and etc. Those were only a few suggestions. If these changes were implemented (not exact changes), then the game would make players grind more and would change PVP. Whenever netherite was introduced, I think mostly everyone was excited and hyped for the change. I think new ores would be a HUGE right step in this update.
