11. Dense Ores
Dense Ores is a new mod for the 1.7 version of Minecraft, which sees the addition of, you guessed it, dense ores. This mod adds “dense” versions of other blocks that will drop 3x the amount of items that a regular ore will, and generates about 1-10 dense blocks per chunk, replacing already generated ores. It’s not perfect, but it saves players the time from having to dig for ores and gemstones.
