Depth Ore Deposits

Depth ore deposits are special ores that form deep underground and can only be destroyed, and therefore drop items, via explosion. They are likely going to be the ideal block to use Mining Charges with.

Utilization
Depth rock allows to get some more difficult materials in mid to early game. When broken, they drop 1 crystal of that material, with some exceptions. The following materials can be found within:


 * Iron
 * Titanium
 * Tungsten
 * Zirconium
 * Drops ~3 splinters instead
 * Cinnabar (Mercury)
 * Drops ~3 pieces instead

Trivia

 * Depth rock drops itself instead of a material.
