Carpentaria Exploration confirms additional magnetite mineralisation at Hawsons Iron project
Carpenteria Exploration Ltd (ASX: CAP) has located historical drill hole data by Placer Exploration dating back to 1993 that confirms the source of the company’s Wonga Anomaly at its Hawson Iron project in western NSW to be magnetite ironstone.
The results are similar to those obtained from Carpentaria drill holes at its Core Anomaly and – along with magnetic modelling - indicates a considerable increase in potential Wonga magnetite tonnages.
There are also additional potential magnetite tonnages interpreted at the Dam Anomaly, said Carpentaria Exploration’s executive chairman Nick Sheard.
“Geological and laboratory analysis shows that the source of the large, 100%- owned Wonga Aeromagnetic Anomaly is magnetite ironstone very similar in character to that recently drilled at the Hawsons Core Anomaly, which is prospective for beneficiation-quality magnetite iron ore. It also gives us confidence that the adjacent Dam
Anomaly is similar material and adds significantly to potential tonnages for this project.”
Carpentaria located a previously misplaced drill-core from a historical Placer Exploration hole, DD93W2, which was drilled on the flank of the 100%-owned Wonga magnetic anomaly. The hole was drilled to test for iron oxide copper gold targets on the flank of the magnetic anomaly. The hole finished in a magnetite ironstone at 147.2 m below collar.
While core from the end of the hole was missing, the 2.2 metres from 141.5 metres down hole or 132 metres below surface was available and quarter core was taken and dispatched for analysis.
The core returned a Davis Tube Recovery (DTR) analysis of 17.43% weight recovery and a concentrate grade of 68.6% iron and 4.3% SiO2 with negligible deleterious elements.
This hole confirms the concept that the Wonga Anomaly’s source can be directly correlated to ironstone at the adjacent core magnetic feature, which is part of the prospective Neoproterozoic Braemar Facies of the Yundamutana Sub-Group.
The modelling of the magnetic anomaly has also confirmed that the Placer hole has only intersected the edge of the magnetic anomaly. The modelling indicates the source is a large mass of magnetite ironstone.
