New Frontier Minerals (LSE:NFM) has identified an untested bedrock conductor within its 100%-owned Harts Range project in the Northern Territory, following independent modelling by Southern Geoscience Consultants.
The London and Australia-listed explorer, focused on heavy rare earths, niobium and tungsten, said the conductor sits roughly 240 metres below surface within tenement EL 34147.
Southern Geoscience modelled the target from Geoscience Australia's publicly available AusAEM airborne electromagnetic data, extending 679 metres in a north-northwest direction, and concluded it is prospective for copper-nickel mineralisation. The conductor lies 3.5km south of the Kings Cross magnetic anomaly, where New Frontier already has government approval to drill a discrete target at similar depth.
It also sits within 40km of the C2 conductor identified through BHP Xplor-backed research published by Litchfield Minerals in June, which interpreted deep conductive architecture beneath the Blackadder-Baldrick nickel-copper-PGE prospects and suggested further conductors may lie undetected across the belt.
No ground electromagnetic surveys or drilling have yet been carried out over the new target.
"The results reinforce our view that Harts Range has the potential to host a much broader mineral system than previously recognised," said chairman Gerrard Hall, adding that the AusAEM data has proven an effective tool for prioritising exploration.
New Frontier plans to review existing magnetic, radiometric and geological data over southern EL 34147, alongside reconnaissance mapping and rock chip sampling along the conductor's projected surface position, while progressing its mining lease application over the Big One Deposit.
News Intelligence what this means for the company
New Frontier Minerals has identified an untested bedrock conductor 240 metres below surface at its Harts Range project in the Northern Territory, following independent modelling of publicly available airborne electromagnetic data. The target sits 3.5 km south of an approved drill site and within 40 km of a district-scale nickel-copper system identified by BHP Xplor-backed research, suggesting the broader Harts Range belt may host a larger mineral system than previously recognised. The company plans reconnaissance mapping and rock chip sampling before any drilling, with no ground surveys yet conducted over the new target.
The identification of a new exploration target adds to New Frontier's prospect inventory at Harts Range, but remains early-stage: no drilling or ground surveys have been completed, and the target is prospective for copper-nickel rather than the heavy rare earths, niobium and tungsten stated as the company's primary focus. This complements the July 2026 field mobilisation we reported earlier, though the investment case turns on whether systematic testing of the 40-target pipeline—including this conductor—yields economic mineralisation.
