Once inside, it's possible to see Dinah in the center of the map welcoming you and around 6 available points to harvest of each resource: copper to the west (left), lumber to the east (right), and amethyst to the north. You can see random characters created by the server and other characters doing the same quests too.
There are only a few quests for Resource Quarry: Resource Harvesting, Copper Shortage, Harvest Amethyst, More Amethyst quests and bounty quests requiring these items. After completing these quests, the items collected in Resource Quarry are automatically removed from your bags.
In wartune 2.1 patch, this map and all the quests related to this map were removed.
