Mining Guild
Located in Dungeon I, the Ladder down to here can be reached from just South-East of Dorpat City, the Mining Guild requires the Player to have a Mining Guild Permission equipped (Lv65 Mining) to be granted access.
The Mining Guild contains the following Ore Deposits: 
Copper, 
Copper Ore, 
Tin, 
Tin Ore, 
Iron, 
Iron Vein, 
Coal, and 
Coal Vein; along with a 
Furnace and 
Anvil.
Due to the Furnace's proximity to the Ores and Anvil, it is a great place to quickly train Forging at lower levels by, for example; smelting the Iron Ores into Iron Bars at the Furnace then Forging the Iron Bars at the Anvil into something that has a high chance of success (like Iron Watering Can), recycling the creations and doing it all over again or selling the results to the various NPC 
vendors that buy such things.
This is also a better place to mine 
Coal since it doesn't require fighting any monsters on the way and is relatively close to Dorpat town chest or Outpost chest.
The Uncut Gems which can be obtained from this location include:
