Copper. Copper (Cu) is an extremely useful industrial metal that is ductile (capable of being drawn into wire), malleable (capable of being hammered and molded) and an excellent conductor of electricity (only silver is better). Copper is found in many minerals
Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the most-used metal

Cut‐off grades of 1.0 % copper for the massive sulphides, 1.25 grammes per tonne gold for any gold zones and 1.0 % copper for the stringer sulphides
Mineral Resources. The Viscaria Project is divided into three deposits: A Zone, B Zone and D Zone. A Zone is a copper-rich deposit with minor concentrations of zinc and gold that was mined by Outokumpu OYJ between 1983 and 1997. Development consisted of
Mineral resources are the key material basis for socio-economic development. Statistical results show that more than 95% of energy used by mankind, 80% industrial raw materials and 70% raw materials for agricultural production are from mineral resources.
2020. 8. 21.· Copper equivalent (CuEQ) calculations use metal prices of $1.85/lb for copper, $902/oz for gold and $12.50/lb for molybdenum, and recoveries of 85% for copper 69.6% for gold, and 77.8% for
16.3 Mineral Resources. Gold-bearing quartz vein from California. Mineral resources, while principally nonrenewable, are generally placed in two main categories: metallic (containing metals) or nonmetallic (containing other useful materials). Most mining is focused on metallic minerals.A significant part of the advancement of human society has been developing the knowledge and technologies
