Mining Lease Application Progresses at Big One Copper Deposit

 

New Frontier Minerals Ltd (LSE and ASX: NFM) is pleased to advise that the
Mining Lease Application ("MLA") over the Big One Copper Deposit, part of the
Company's NWQ Copper Project in north-west Queensland, has progressed into the
technical assessment phase. The Queensland Natural Resources and Mines
Department has confirmed completion of the initial regulatory review and is
now undertaking a detailed technical assessment of the MLA.

 

Highlights:

 

·    Mining Lease Application (MLA) over the Big One Copper Deposit has
advanced into technical assessment, following completion of the initial
regulatory review by the Queensland Natural Resources and Mines Department

·    The Big One Copper Deposit hosts a JORC-compliant Mineral Resource of
2.1Mt @ 1.1% Cu ( 1 ), and an additional 7,000t @ 1.3% Cu of surface Indicated
stockpiles, positioning Big One as a potential near-term cash flow opportunity
( 2 )

·    Established processing pathway identified via haulage to Austral
Resources' Mt Kelly Processing Facility, subject to approvals and economics
( 3 )

·    Sulphuric acid leach test-work has delivered indicative copper
recoveries of up to 99%, confirming suitability for conventional acid leach
processing ( 4 )

·    Proposed initial activities would target near-surface copper
mineralisation and the transport of existing historical stockpiles, supporting
a low-strip, surface-based development approach

·    Further resource drilling could potentially extend known
mineralisation at the Big One Copper Deposit, where key historical intercepts
included:

o  BH 303RC: 40m @ 1.64% Cu from surface incl: 11m @ 4.40% Cu from 24m, 5m @
7.34% Cu from 28m & 1m @ 16.65% Cu from 29m ( 5 )

o  BH 301RC: 44m @ 1.19% Cu from surface incl: 14m @ 3.55% Cu from 27m, 3m @
10.88% Cu from 37m & 1m @ 12.6% Cu from 37m ( 5 )

o  BH BO017: 34m @ 1.51% Cu from surface incl: 21m @ 2.25% Cu from surface,
12m @ 3.44% Cu from 3m, 6m @ 4.79% Cu from 3m and 1m @ 9.4% Cu from 9m ( 6 )

·    The current copper upcycle has seen the copper price exceed
US$12,500/t, driven by supply disruptions and strong demand associated with
global electrification and the ongoing energy transition.

 

Chairman Gerrard Hall commented: "Advancement of the Mining Lease Application
into technical assessment represents an important milestone for New Frontier.
The Big One Deposit offers a compelling opportunity to potentially process NWQ
ore at the existing Mt Kelly Facility, leveraging existing infrastructure and
established processing pathways, while continuing to engage constructively
with regulators."

 

BIG ONE DEPOSIT

The MLA for the Big One Deposit (Figure 1) represents a significant milestone,
strengthening New Frontier's position across the broader NWQ Copper Project,
which is located within a well-established district hosting multiple operating
mines and development projects with access to regional infrastructure and
processing facilities.

 

The MLA is supported by an Initial Development Plan outlining a potential
open-cut mining scenario designed to test and extract near-surface copper
mineralisation. Subject to approvals, preparatory earthworks are expected to
commence in Q3 2026.

 

The development plan proposes mining and haulage to the Mt Kelly Processing
Facility, operated by Austral Resources Ltd.

 preparation activities, including the bulk sample zone, laydown area,
 stockpile, and access tracks

 

AUSTRAL RESOURCES - MEMORANDUM OF UNDERSTANDING

The MLA builds on the Memorandum of Understanding ("MoU") signed earlier this
year between New Frontier and Austral Resources Ltd ( 2 ), which established a
framework for evaluating toll treatment and ore supply opportunities at the Mt
Kelly Copper Processing Facility (Figure 2). The lodgement and advancement of
the MLA represents another step toward potential near-term development of the
Big One Deposit within the broader NWQ Copper Project.

 

Sulphuric acid leach test-work conducted on material sourced from the Big One
historical stockpiles has delivered indicative copper recoveries of up to 99%,
confirming suitability for conventional acid leach processing ( 3 ). The
results indicate favourable mineralogy and rapid copper dissolution under
standard conditions, supporting a simple, low-risk processing flowsheet and
reinforcing the viability of toll-treatment via Austral's Mt Kelly Processing
Facility.

 

The proposed operation is designed to leverage the site's existing footprint,
including previously disturbed pits and infrastructure, minimising surface
impact and supporting New Frontier's commitment to responsible development.

NEXT STEPS

·    Continue engagement with the Queensland Natural Resources and Mines
Department as the MLA advances through the technical assessment.

·    Progress assessment of priority mining areas and historical stockpiles
outside the current Mineral Resource Estimate.

·    Receive and assess assay results from the Harts Range Heavy Rare
Earths drilling program.

·    Progress the proposed OTCQB listing in the United States, with the
application submitted and approval pending.
