The largest reserves are found in Siberia, the Central Asian republics, India, and especially China; Indonesia, Japan, and North Korea have smaller but nevertheless economically important reserves. China has chiefly high-grade coal reserves.

Copper isotope ratios differ between hypogene sulfidic, supergene sulfidic and oxidized ore sources. Traditional lead isotope signatures of ancient metals are specific to deposits, while Cu isotope signatures are specific to the types of ore minerals used for metal production in ancient times. Two methodological case studies are presented: First, the mining district of Faynan (Jordan) was

Jan 25, 2020· The ability to extract copper from ore bodies was well-developed by 3000 BCE and critical to the growing use of copper and copper alloys. Lake Van, in present-day Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths, who used the metal to produce pots, trays, saucers, and drinking vessels.

The preeminent epithermal gold deposit in the ANS is Madh adh Dhahab – meaning Cradle of Gold – is a polymetallic Zn-Cu-Au-Ag deposit. Mahd adh Dhahab is operated by the Saudi Arabian Mining Company (Ma’aden) and in 2014 produced 34,280 oz gold from 200,710 Mt ore grading 5.95 g/t Au.

The six early studies reported by Griffin (Ref.25), all report native copper at 99.92% copper. Rapp and others (Ref.8,53) report that using trace element “fingerprints”, using mostly Lake Superior copper samples, probable geographic/geologic source identification can be done.
