This mod adds several Prospecting Hammers, tools that when right clicked on a block will tell you (through chat) if there are any ores in a range dictated by the hammer material, and what kind it is.
The Hammers are as follows:
Range is the number of blocks searched in each direction, in the Width X Height X Depth format, where Width is X for most Block Facings and Z for East and West, Height is Y for anything not Up and Down, and Z for Up and Down, and Depth is forward from where you're aiming at, so Y for Up and Down, X for West and East and Z for North and South.
There are plans for adding mod support for some common materials later, such as steel and bronze.
