The zinc-copper-lead ore will be processed into a concentrate, while we'll refine the gold-silver ore into semi-pure bars, called dor bars. During an average year, we'll produce 73,000 tonnes of zinc concentrate, 7,300 tonnes of copper concentrate, and 3,400 tonnes of lead concentrate. Also, we'll provide an average of 67,000 oz of gold.
