Lord Resources (ASX: LRD) has identified prominent gravity anomalies coincident with known copper mineralisation at the Ilgarari Copper Project in Western Australia.
The survey was completed by Atlas Geophysics with data collected on a 200m x 100m grid across the entirety of tenement E52/2274.
The key findings include a prominent gravity low directly mapping the Ilgarari Fault. The strongest gravity low features are interpreted as zones of dilation, which coincides with areas of known copper sulphide mineralisation and historical workings. Dilation zones within faults allow for increased fluid flow, changes in pressure and a structural trap for potential mineralisation.
Additionally, a second gravity low has been identified further northeast along the Ilgarari Fault, indicating additional structural complexity and significant exploration potential.
The survey has identified several gravity high features in the footwall zone of the Ilgarari Fault, aligning with chargeability anomalies from previous IP surveys which highlight potential zones of dense, chargeable drill targets.
“The results of the gravity survey have exceeded expectations, with several significant anomalies providing valuable new targets for exploration," CEO, Andrew Taylor, said.
The gravity low mapped along the Ilgarari Fault confirms its role as a key mineralised structure, and the identification of additional gravity anomalies further enhances the project’s potential.
As we begin major exploration programs, these results bring us one step closer to unlocking the full potential of the Ilgarari Copper Project.”
A ground-based EM survey will now be planned to accurately map subsurface features associated with the gravity and IP anomalies, providing critical insights into potential copper sulphide mineralisation along the Ilgarari Fault.
The EM survey will provide detailed geophysical data to refine the understanding of subsurface features, including their size, depth, and orientation. This information will be integrated with the existing gravity, IP, and magnetic survey results to accurately delineate high-priority drill targets and maximise the likelihood of intersecting mineralisation.
The survey will be designed to cover both the Alac and Main zone in addition to additional gravity low defined by the recent survey.
