Custom Ore Generation: First Revival Mod has been designed to allow players to decide the kind of ores generated in their worlds and how these ores are distributed.
Like the name suggests, Customization is the main objective of this mod. As a result, you are able to change any aspect of the ore generation through the flexible config file and the more succinct in-game menu.
Please see the original thread for more information. Hope this revival of the venerable Custom Ore Generation will satisfy you.
