Ores of the “reduced type” are sulfides or sulfosalts (chalcocite, chalcopyrite, tetrahedrite), and are not readily identified in outcrops as ores; they require roasting to convert them to oxides, then reduction of the oxides to produce metal.
There are a number of places in the world where copper can be found in small deposits in the pure state, but it is usually embedded in a rock matrix, from which it must be freed by intensive labor, or, today, crushed in huge volumes, and treated to obtain the metal.

However, these studies claim that the 10 tons of copper oxhide ingots recovered from the late Bronze Age (1300 BC) Uluburun shipwreck off the coast of Turkey was “extraordinarily pure” (more than 99.5% pure), and that it was not the product of smelting from ore.
The oxhides are all brittle “blister copper”, with voids, slag bits, and oxides, created when the oxhides were made in multiple pourings outdoors over wood fires.
