Surrounding the Kanmantoo Operation and extending for over 6,000 sq kms in the south-east of South Australia, Hillgrove is exploring for Cu porphyry and sediment hosted Cu-Au deposits.
Hillgrove hold 100% of a series of Exploration Licenses covering 6,141 sq kms in south-east South Australia in the Cambrian-Ordovician Kanmantoo Province. Over 95% Of the Kanmantoo Province is covered by the Tertiary Murray Basin which has limited past exploration.
Recent work by Hillgrove and the GSSA has highlighted the opportunity for large scale Cu-Au deposits including;
The licenses comprise three geographic groups:
“Winu” style sediment hosted alteration and sulphides have been identified at several sedimentary basins in the Dukes Project area in legacy drill holes and require further investigation including,
Note: All the exploration company legacy drill holes were focused on testing airmagnetic anomalies and therefore are biased against discovering sediment hosted mineralisation.
Multiple small Cu-Au workings in contact metamorphic aureole of magnetite-amphibole diorites.
In addition, HGO’s geochemical sampling of its own and legacy drill holes and outcrops shows a number of areas in the Kanmantoo Province with attractive Cu fertility indexes, in particular along the Coorong Shear Zone corridor. GSSA’s recent work at Anabama supports these fertility indexes along this zone (note the red labels in the fertility plot). Further south in Hillgrove’s tenement area is a small outcrop of Cu-Mo porphyry.
In summary, Hillgrove have identified a suite of over 70 prospects for further work within their exploration project areas.
