ASARCO » Mining

A number of mine plans based on different metal prices can be developed to help the mine better respond to changing market conditions. When the price of copper is high, lower-grade ore can be cost-effectively mined along with the better grade ore. When the price is low, the mining operations can focus on the higher grade ores.
