Tali Resources (ASX:TR2) will begin diamond drilling at the Khya prospect in mid-August to test a concealed copper–gold target at its West Arunta Project in Western Australia.
A single hole is planned to test overlapping gravity and magnetic anomalies on the southwestern side of a broadly circular, 3.5km-wide magnetic structure within the Lake Mackay Fault Zone.
The priority gravity target extends for about 2km and partially overlaps the strongest section of the magnetic anomaly. Modelling indicates the target begins about 275m below ground and can be tested by a hole extending to around 700m.
Passive seismic data places the depth to bedrock at approximately 250–300m across the prospect.
Tali interprets the magnetic feature as a felsic to intermediate intrusive ring dyke above a deeper, less magnetic intrusive body. The company says the gravity anomalies may represent alteration or veining around the intrusive complex, or a denser mafic phase.
Managing Director Rhys Bradley says the combination of the circular magnetic structure, gravity anomalies, and structural setting makes Khya prospective for an intrusion-related copper-gold system.
“With additional geophysical interpretation, EIS [Exploration Incentive Scheme] co-funding secured, and all approvals in place, we are looking forward to drill testing Khya in mid-August,” Bradley says.
The Geological Survey of Western Australia has awarded Tali an $270,000 Exploration Incentive Scheme co-funding grant for the hole. Heritage and regulatory approvals are in place.
Tali says it has prioritised Khya over the nearby Vanda prospect, which contains several more complex gravity and magnetic anomalies.
The company notes it has also completed aircore drilling at five other West Arunta prospects. Aircore drilling is scheduled to resume in late September after the Khya hole is completed.
