"The projected manganese (“Mn”) content of the final zinc concentrate is 1.32%, in line with the preliminary metallurgical test work."
As previously disclosed, Arizona Mining has done initial bench-scale metallurgical work on the various types of ore found at the Taylor deposit which does not yet reflect cleaner stages, regrinds or any optimization, which may reduce the manganese levels. The same initial results show very low iron and cadmium contents and negligible mercury and arsenic, which are other common undesirable elements.Initial work indicates a manganese content of approximately 0.1% in the lead concentrate and approximately 1.3% in the zinc concentrate. As previously noted, the penalties for a zinc concentrate containing 1.3% manganese are estimated to be $12 per dry metric tonne versus the zinc concentrate value of over $1,100 per dry metric tonne at a $1.00 per pound zinc price. This equates to approximately 1% of the estimated concentrate value and is therefore immaterial.
“We would be prepared to purchase as much of the zinc concentrates, at market, without penalty, as we could.”
