7.2.3.4 Copper Oxide Mineralization
Copper mineralization has been intersected within both the hangingwall and footwall zones of Copperstone. The majority of Copper mineralization intersected by drilling is of oxide state and is understood to be primary. Oxide copper occurrence in drilling intercepts ranges from moderately coarse vein fill within structural zones to residual staining along thin margins. Predominate copper mineral occurrence is identified as malachite and chrysocolla. Intercepts containing native copper do occur at Copperstone as infill within veins and within dilational shears. Sulfide copper mineralization such as bornite and chalcopyrite are found at Copperstone but in lower occurrence relative to both oxide and native speciation. Recent metallurgical testing of historic samples from B zone materials did identify a small area containing anomalous concentration of sulfidic copper. Copper assay data was not typically not collected during historic drilling and sampling programs. Kerr incorporated copper assays into the 2017 exploration program and plans to continue collecting copper assay data during future drilling and sampling.
A direct association of gold with copper is not established even though both occur in economic concentrations. Virtually every dataset shows no correlation between the two metals. While they may occur within the same vicinity of a drillhole, they seldom occur in significant grades in a single body. Hole KER-17U-53 is a rare example. The current theory is that they are of separate phases that were depositing when certain structures were open to hydrothermal fluids. Timing of various geological structures and mineralizing fluids appears to be very important in the distribution of metals. The geochemistry of the Copperstone deposit may be amenable to a factor analysis treatment to discover elemental associations that are not visible to the casual eye. As more multi-element data is obtained, this should be carried out on a domainal basis by the recognized zones...." https://kerrmines.com/wp-content/uploads/KerrCopperstone_PFS_43-101.pdf Last February I directly asked Giulio about Copper at Copperstone and he stated gold production is the focus but that eventually copper will be... https://www.globenewswire.com/news-release/2020/01/28/1976058/0/en/Candente-Copper-Corp-appoints-Giulio-T-Bonifacio-as-Director.html
