New Frontier Models Untested Copper-Nickel Target at Harts Range

Independent Modelling Reveals New Exploration Target

New Frontier Minerals Limited (ASX:NFM) has unveiled a fresh high-priority copper-nickel exploration target within its 100%-owned Harts Range tenement EL34147 in the Northern Territory. Independent consultants Southern Geoscience Consultants (SGC) modelled a concealed bedrock conductor approximately 240 metres below surface using publicly available AusAEM airborne electromagnetic data from Geoscience Australia.

This conductor lies about 3.5 kilometres south of the Kings Cross magnetic anomaly, where New Frontier recently secured government approval to commence drilling. The new target, interpreted as a single flat-lying plate striking 679 metres in a north-northwest direction, adds a compelling dimension to the project’s copper-nickel potential.

Geophysical Evidence Supports District-Scale Potential

SGC’s modelling suggests the conductor is prospective for copper-nickel mineralisation, reinforcing the emerging view that Harts Range hosts a much broader mineral system than previously recognised. The target sits within 40 kilometres of the C2 conductor identified by BHP Xplor-backed research through Litchfield Minerals Limited (ASX:LMS), which has redefined the region as a district-scale nickel-copper-PGE province.

Chairman Gerrard Hall emphasised the significance of the geophysical findings, noting the conductor’s proximity to the C2 anomaly and the utility of airborne electromagnetic data in uncovering concealed bedrock features. “While this is an early-stage geophysical target, the results reinforce our view that Harts Range has the potential to host a much broader mineral system than previously recognised,” Hall said.

Untested Target Requires Ground Verification

The conductor remains untested by ground electromagnetic surveys or drilling. The data underpinning the modelled plate comes from a single AusAEM flight line, limiting constraints on the anomaly’s extent and geometry. Electrical conductivity anomalies of this kind can be caused by various sources, including sulphides, graphite, saline groundwater, or clay-rich sediments, meaning the geophysical signature is non-unique.

New Frontier plans to follow up with ground electromagnetic surveys to confirm the conductor’s presence and characteristics, alongside reconnaissance mapping and rock chip sampling along its projected surface position. These steps will help prioritise any future drill testing, which is not currently scheduled.

Strategic Positioning Amid Broader Exploration Activity

The Harts Range project has gained increasing attention following the BHP Xplor-backed research that identified key geological ingredients for large copper-nickel sulphide systems in the area. New Frontier’s discovery of this untested conductor complements its ongoing exploration efforts, including the approved drilling at Kings Cross and a wider portfolio of rare earth, niobium, and copper assets across Australia and Canada.

This announcement arrives as New Frontier continues to ramp up activity at Harts Range, where 40 untested high-priority prospects remain, including magnetic and electromagnetic anomalies. The company’s approach of leveraging publicly available datasets to identify concealed targets demonstrates a cost-effective strategy for expanding its exploration footprint.
