This Minecraft mod provides items called Dowsing Rods which can help find ores and other blocks. When you right-click with a Dowsing Rod it highlights ores which it finds in a cube around you (sized from 9x9x9 to 17x17x17 depending on the tier). Which ores it highlights is also dependent on the tier. See the wiki for more details.
