Over half of the goethite analyses showed no Co present, and, as such, there are two types of goethite in the Piau deposit, Co-free and Co bearing manganoan goethite . Although Co was only present in manganoan goethite, there is a distinct correlation between Co and Ni within the goethite ( Figure 12 ), with correlation values of 0.65 between Co and Ni compared to 0.56
