The major portion of the production from the Bisbee mines of the company is mined by these methods. The total average yearly production for the last two years has been 493,612 tons of 5 per cent copper ore. The average employment in the mining department eras 940 men. With the exception of a small tonnage mined for the high iron and sulphur content, the ore is direct-smelting and is mined for its copper conntent and associated gold and silver values.
