Fifty mines produced lead silver gold and zinc that fed the smelters which could process a total of more than 700 tons of ore a day By 1879 mining had reached well below the water table and the increased cost of pumping the water out of the mines began to make mining deeper less profitable Eureka mining production peaked in 1882 but tailed off rapidly after 1885 and by 1891 the major
