THE SEQUENTIAL COPPER ANALYSIS METHOD – UPDATE

The Seq-Cu method is particularly applicable to copper deposits which exhibit varying degrees of oxidation and leaching, which is commonly associated with large, porphyry style copper deposits. In such cases, the deposit will often show a “top -down” mineral zonation from leached capping with low copper content, to an oxidized zone with
