Branch mining is effective because you can acquire a lot of ores efficiently. However, this type of mining consumes many tools because of the volume of stone you dig through, and produces much more cobblestone than valuables. Branch mining is a helpful method if you have patience, and a project in which you can invest your fortune of cobblestone.

A mining plan employing narrow vein mining techniques was prepared for the PEA. The crest areas would be mined using mechanised drifting methods. The limbs would be mined using narrow vein stoping methods such as longhole stoping or thermal fragmentation.
Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping.
