Sican tumi, or ceremonial knife, Peru, 850–1500 CE. Metallurgy in pre-Columbian America is the extraction, purification and alloying of metals and metal crafting by Indigenous peoples of the Americas prior to European contact in the late 15th century.
Mount Gabriel located close to west Cork provides useful evidence for the exploitation of copper ore in the Early Bronze Age about 1700 BC. Through research thirty-two areas of activity were underlined. Shallow concaves and significant amount of dump with charcoal and tools are the evidences of Bronze Age copper extraction in the region.
Copper was probably the first metal mined and crafted by humans. [8] It was originally obtained as a native metal and later from the smelting of ores. Earliest estimates of the discovery of copper suggest around 9000 BC in the Middle East. It was one of the most important materials to humans throughout the Chalcolithic and Bronze Ages.
Copper bells, axe heads and ornaments from various parts of Chiapas (1200–1500) on display at the Regional Museum in Tuxtla Gutierrez, Chiapas..
