I think its one Potassic
A lot of variables.
For example
bornites - it depends who (Bornites) hanging out with (what metals elements mixed with) at the party
This can be telling you low Sulphurdation or high depends on metals its hanging with !!

As Steve says there is quite a contrast between them all

Type 1. Patassic ( seems CC is Type 1)

Type 2. Phyllic is à( later stages of alteration ) type 2

Most of the copper higher grades in the potasic zone (left colum ) are at higher temperatures

Cadia NSW is Type 1 – slightly cooler temperatures to batu hijau but in potassic Colum
