 
The Public Mining Zone or PMZ is an entirely separate world for gathering resources. The entrance to the PMZ is located right next to spawn down the Obsidian hole.
The purpose of the PMZ is to provide fresh resources to the server without having to destroy the main world. We do not want strip mines, floating trees, cleared forests, and so on in the main world. Please do all large scale mining, deforestation, etc. in the PMZ.
The PMZ will be refreshed weekly so it is not recommended that you build structures you want to keep, or leave large amounts of materials behind. These may get deleted without warning!
