The Garfield prospect was discovered by Renison Goldfields Consolidate in 1994.
The mineralisation style is comparable to the Prince Lyell ore body at Mt Lyell which is a low-medium grade porphyry Cu-Au style system.
The sericite-chlorite alteration system that surrounds Garfield extends for more than 7km in which are several other targets that haven’t been tested.
Drilling at Garfield by Corona limited the potential for economic development for Garfield itself but highlighted the potential for some of the other targets in the Garfield camp, for example high sulphidation alteration was discovered by Corona staff 1km north of Garfield associated with elevated Cu (2000ppm).
Typically in Porphyry systems the main mineralisation is to be found underneath the high sulphidation alteration areas. In the case of the target 1km north of Garfield an IP anomaly has been recorded 200m below the surface outcrop of high sulphidation alteration and copper mineralisation.
