  • How Is Copper Formed? | Reference

    Copper forms as molten rock with small amounts of copper fluid crystallizes. As the larger rock continues to solidify, the fluid rich in copper moves into cracks, eventually solidifying as well. Because the copper solidifies later than other minerals within the larger rock, the final deposits have a high concentration.
