[10] The only production remains of metal are those of copper and include copper slag, prills, and amorphous copper lumps and small shallow ball-shaped clay crucibles ...
Evidence for mining in the Vilabouly complex include mining shafts and evidence for the materials that were mined. In the complex, there are ancient wooden structures that support mining shafts at sites such as Khanong A2 and Tengkham South D. [2] At Khanong A2, archaeologists have found over 130 well preserved mining shafts. The wood in these ...

Onaping Fallback Breccia, polished slab, 15 by 23 cm (6 by 9 in) The Sudbury basin formed as a result of an impact into the Nuna supercontinent from a large impactor body approximately 10–15 km (6.2–9.3 mi) in diameter that occurred 1.849 billion years ago [2] in the Paleoproterozoic era.
In fact, one of the possible explanations about what Ötzi the Iceman, the ancient mummy found in the Alps who lived around 3300 years BCE, was doing at 3,210 metres (10,530 ft) of altitude is that he could have been prospecting for new ores of minerals. [10] Secondly, the mineral is separated from the gangue.
Parys Mountain was mined for copper ore in the early Bronze Age, as shown by sub-surface debris nearly 4,000 years old revealed during excavations in 2002.Since then, access has been regained to the sealed underground workings of the Parys mine, revealing further evidence of ancient mining.
These deposits are typically very far underground in ancient riverbeds, beaches, or slopes. [7] The Witwatersrand Basin, South Africa is the largest gold deposit in the world and is considered a paleo-placer, it has produced over 1.5 billion ounces of gold. [7] The Witwatersrand Basin is considered an ancient alluvial placer. [7]
The Old Copper Complex of the Western Great Lakes is the best known, and can be dated as far back as 9,500 years ago. [ 4 ] [ 1 ] Great Lakes natives of the Archaic period located 99% pure copper near Lake Superior , in veins touching the surface and in nuggets from gravel beds.
