Copper can be found in small quantities all over the map. One place to mine copper ore on the map is at the carpenter's camp. In addition to a few veins of ore, you will also find clay there. Other good places are the Wistful Fields or the cave near Willow Crush. The best place to mine the valuable ore is at Sameth's Legacy.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
