From Vintage Story Wiki
As soon as the player acquires a pickaxe and hammer, they should return to the spots were nuggets were previously found on the surface. The player can dig down under these spots to find shallow native copper veins. They are not as large as their underground counterparts, but will give enough copper to start into the further metal ages. The pickaxe is necessary to dig stone and the ore once found - the hammer is required to break the ore chunks into usable nuggets.
