South East South Australia
In addition to the Kanmantoo operation, Hillgrove holds over 6,150kms² of granted Exploration Licences in south eastern South Australia which are highly prospective for discovery of economic copper deposits within a variety of geological settings.
The Company's tenements are all located within the Delamerian orogen. In a recent publication by the Geological Survey of South Australia, the Survey notes the similarities between the Delamerian Orogen tectonic setting and its high-level granitic to dioriticintrusives in South Australia, with the geology of the large Porphyry Cu-Mo-Au deposits in south-east China (e.g. Dexing, 9.7Mt of Cu metal, 265 t Au)
These observations support Hillgrove's exploration activities in this Orogen for large scale Cu-Au deposits.
The Exploration Licences comprise two geographic groups;
Location of Kanmantoo Copper Mine and regional exploration targets
Stella is located around 1.5 kms south east of the Kanmantoo processing plant. At Stella, Hillgrove has defined a large conductive geophysical anomaly beneath historic drilling which has intersected broad zones of alteration with copper-gold mineralisation. The closest drill hole to the geophysical anomaly KAN001 intersected the following;
The strong gold endowment within close proximity to Kanmantoo make Stella a priority target for follow-up.
North West Kanmantoo is located 4.5kms north west of the Kanmantoo processing plant and covers a 2.3 km long zone of copper-gold anomalism associated with Fe gossans and breccias.
Hillgrove’s regional tenements are prospective for a variety of mineralisation styles, including; porphyry, skarn, epithermal and epigenetic copper +/- gold mineralisation with the following examples within the district highlighting this variety;
The six south eastern tenements of the project lie within an area identified by a joint study of the United States Geological Survey (USGS) and Geoscience Australia (GA) as being a porphyry copper province with stratigraphic and tectonic links with western Victoria’s Stavely porphyry copper belt.
