Harts Range Drilling Campaign Nearing Completion,

 Samples Await Assay Analysis

 

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, USA(2)

·    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 facility(3)

 

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.
