Impact Minerals (ASX: IPT) is preparing to follow-up on the district scale potential of its Broken Hill project in New South Wales.

Results from a single-line magneto-telluric (MT) ground geophysical survey has unveiled a number of significant near-surface conductive targets that the company believes may be linked to deep-seated structures within the project.
MD, Dr Mike Jones, said the conductors lie within the central part of Impact’s extensive ground holdings surrounding the world famous Broken Hill silver-lead-zinc deposit, which contains over 500 million tonnes of massive sulphide mineralisation.
“The significance of these results lies not just in the individual conductors we have identified, but in what they may represent at a district scale,” Dr Jones said.
“The MT data suggest the presence of a deep crustal corridor capable of focusing mineralising fluids into the upper crust, precisely the type of architecture associated with world-class mineral provinces.”
Impact holds 100% of the tenements covering approximately 2,000 sq. km and over 100 km of prospective strike, making it a leading ground-holder particularly south of Broken Hill.
‘Broken Hill is proof that this region has the capacity to generate giant ore systems. What has been less understood is the deeper plumbing that fed those systems. Our work indicates that these fundamental controls may extend into areas that have seen little modern exploration,” Dr Jones said.
“Although further validation is needed, confirming shallow conductive targets above a deep- seated corridor provides us with a strong geological framework. This type of large-scale structural setting can support significant discoveries.”
Previous studies identified three near-surface conductive zones, with follow- up work confirming a discrete conductor at the top of the priority T3 anomaly
Dr Jones said the results align with a reinterpretation of regional AUSLAMP MT data, supporting a model of deep fluid pathways capable of producing large mineral systems.
Impact is now waiting on results from a follow-up MT survey over T3 completed with final inversion results pending ahead of drill targeting.
IPT is steady at 6.2¢. Mkt cap $29.41M.
