Established Australian copper producer and explorer Aeris Resources (ASX: AIS) has provided an update on its 70% owned Torrens Exploration Project in South Australia.
· Assays received from drillhole TD10
· Drillhole TD10 aided with advancement of geological understanding
Assay results for drillhole TD10 have been received. TD10 was targeting a significant coincident gravity and magnetic anomaly with a footprint of approximately 3km2, situated some 9 kilometres from the western edge of Lake Torrens in an area where no previous drilling had occurred (all previous drillholes that reached target depths were within 4 kilometres of the shoreline).
Drillhole TD10 intersected intensely altered rocks dominated by K feldspar and variable quantities of magnetite and hedenbergite. Assay results indicate only weakly elevated pathfinder elements reported e.g. copper, rare earth elements etc. The highest copper assay (3.0m @ 0.18% Cu from 1,188m downhole) was associated with a zone of faulting and increased fracturing including the occurrence of minor hematite along fractures.
Whilst copper mineralisation within this zone was minor, it does support the current geological model of targeting geophysical anomalies in proximity to interpreted fault structures.
The two drillholes completed to target depth from the current program intersected dense rock types which are interpreted to account for the geophysical anomalism. Within the tenement there remain many untested geophysical anomalies which will be the focus of ongoing geological investigations.
