Grab samples in 2007 taken from the Cu/Au-rich portion of the tailings dam returned assay values of 1.4g/t gold and 1% Cu, reflecting the 8-12% Cu RoM mill feed established between 1898 and 1953. Much of the Excelsior stockpile and nearby Quiulacocha tailings dam adjacent to the mine was acquired in 2012 by Cerro
Indeed, it has signed an off take agreement with a Chinese firm specializing in transforming zinc and lead, Yunnan Xiangyun Feilong Nonferrous Metal Co. In addition to Kabwe's slag heaps, BMR controls the mine's underground prospects which contain 51 million tons with a combined average grading of the two minerals of 4.01% (uncertified JORC).
The continuous extraction and application of low-grade ores can increase the disposal of mine tailings in the future. As long as the disposal of mine tailings is not properly managed, they not only cause severe contamination, but also bring about undeniable economic problems [6], [7], [8]. Reusing mine tailings help protect the environment.
