    New Mine Capacity From Yettobe Found Copper Deposits

    Jun 01, 1985 Low prices, rising costs and falling copper grades have forced some of the largest mines in the country to close. As a result, US copper mine production fell from 1600000 tonnes in 1973 to 1000000 tonnes in 1982. Given competitive markets, the only way to reverse this trend is to find and mine additional high-grade copper deposits.
