This mod add 3 new rarer ore with swords and pickaxes : Osmium, Thorium and Yttrium.
This 3 ores are rarer than the diamon and offer more powerfull tools.
In order to craft it, you have to melt the ore on the Raw Ore Foundry to have melted ore. Once you have this melted ore, you can use the Moulding Machine to craft a pickaxe head or a sword blade.
Swords make more damage and Pickaxes are more efficient.
This is how the Raw Ore Foundry works :
