Harts Range Drilling Campaign Nearing Completion

New Frontier Minerals Ltd (LSE and ASX: NFM) is pleased to advise the inaugural drilling campaign is nearing completion at the Harts Range Project located 140km north-east of Alice Springs in the Northern Territory, Australia. All samples will be dispatched to ALS Adelaide prior to Christmas for assay analysis with insights and interpretation released to the market as results materialise.

Highlights:

• The inaugural reverse circulation (RC) drilling campaign at the Harts Range Project is nearing completion (Figure 1)1
• New Frontier's geology team are pleased with progress, having drill-tested all high-priority targets, to provide insight into the geology and extent of the heavy rare earth mineralisation
• All samples from the drilling campaign will be dispatched to ALS Adelaide prior to Christmas for comprehensive assay analysis, with results to be announced as results are received

• New Frontier continues to progress the commercial framework with Metallium (ASX: MTM), and assess the 25kg bulk sample (from Harts Range) at MTM's facility in Texas, USA2
• The Mining Lease Application (MLA) for the Big One Deposit is progressing, with the objective to assess and process existing stockpiles and surface mineralisation at Austral's (ASX: AR1) Mt Kelly facility3

Gerrard Hall, Chairman, commented:

"2025 has been a truly transformative year for New Frontier. We have advanced the potential of the Harts Range Project, lodged the mining lease for the Big One Deposit, and secured strategic partnerships with Metallium and Austral Resources-providing clear development pathways at a time of strengthening demand for heavy rare earths and copper.

The Board looks forward to the incoming drill results from Harts Range and continued progress at Big One, both of which offer substantial potential to create shareholder value. As we close out 2025, we would like to thank our shareholders for their continued support and look forward to a strong and prosperous 2026."

DRILLING CAMPAIGN NEARING COMPLETION

The reverse circulation drilling campaign at the Harts Range Project is progressing on schedule and within budget, with the drilling campaign nearing completion. Importantly, all high-priority targets have been systematically drill-tested, to provide a strong geological understanding across the project area. The geology team is optimistic the insights from the drilling campaign will provide a significant understanding of the underlying heavy rare earths system, especially the extent of dysprosium and terbium mineralisation.

Sample batches will be dispatched to ALS Adelaide for assay analysis, with results expected to deliver valuable insights into the scale and continuity of the heavy rare earth system.

BIG ONE DEPOSIT - MINING LEASE APPLICATION

The MLA for the Big One Deposit represents a significant milestone, strengthening New Frontier's position across the broader NWQ Copper Project, which lies within one of Australia's most proven districts for structurally controlled copper mineralisation. This proven district hosts multiple operating mines and development projects, providing New Frontier with access to established regional infrastructure and processing pathways.

The MLA lodged covering the Big One Deposit, within NWQ Copper Project, in the Mt Isa copper belt, north-west Queensland covers 240Ha, securing tenure over the historical workings and surrounding mineralised structures. An Initial Development Plan outlines the potential open-cut copper mining, with the layout of the proposed operation in Year 2 illustrated in Figure 2 below.

The MLA builds on the MOU signed earlier this year between New Frontier Minerals and Austral Resources, which established a framework for evaluating toll treatment and ore supply opportunities at the Mt Kelly Copper Processing Facility.
