DISCOVERY OF NEW DRILL TARGET AT HEADINGLEY PROSPECT

Assay results from the July 2025 field campaign have identified additional heavy rare earth and titanium mineralisation, extending the mineralised corridor along strike from the Cusp, Bobs, Paddington,  Westminster and Old Trafford Prospects (Figure 4).

Analysis of the geochemical results from the newly identified Headingley Prospect have confirmed the occurrence of rare earth and titanium mineralisation within a 2.3 kilometre mineralised corridor extending along strike from the Cusp, Bobs, Paddington, Westminster, and Old Trafford prospects. Notable results include HRS067, which returned 0.73% TREO, incorporating 0.031% Dy₂O₃ and 0.006% Tb₄O₇, and HRS068 and HRS071, which recorded titanium grades of 1.8% TiO₂ and 2.3% TiO₂ respectively.

The newly identified Headingley Prospect located approximately 620 metres west of the Bobs Prospect, is seen to be hosted within a mineralised amphibolite unit. Field observations identified a ferruginous, dark black-green amphibolite unit along a shear zone, in contact with an unmineralised pegmatite. This unit is likely a continuation of the Old Trafford structure, located approximately 70 metres further west.

Rock samples from the site are notably dense and returned readings of approximately 10 μSv/h, consistent with mineralisation observed at the Old Trafford Prospect. Preliminary field identification suggests finely disseminated samarskite within the altered amphibolite matrix. The amphibolite unit is oriented in an east-west direction, reinforcing the structural context to the mineralised setting.

AUSTRALIAN GOVERNMENT'S PROPOSED FLOOR PRICE ON RARE EARTHS

The Albanese government is exploring mechanisms to establish a floor price for rare earths and other critical minerals, responding to U.S. efforts to counter China's dominance in the sector⁴. Through a proposed Critical Minerals Strategic Reserve and national offtake agreements, the initiative seeks to ensure price stability, reduce market volatility, and attract private investment.

The focus is on minerals critical for strategic and defence applications, particularly heavy rare earths, where Australia holds a strong global supply position. New Frontier Minerals is well-positioned to benefit, with its Harts Range Project in the Northern Territory hosting significant heavy rare earth mineralisation.

PROPOSED ISSUE OF PERFORMANCE RIGHTS

Subject to shareholder approval at the 2025 AGM, the Board has resolved to issue 17,500,000 Performance Rights to Director and key executives of the Company, on the following terms:

·          Exercise price: $nil

·          Vesting conditions:

o  50% upon the 20-day VWAP of the Company's Shares being equal to or greater than $0.02.

o  50% upon one of the below milestones being met:

·    Harts Range drill intersect of either:

·    5m intersect ≥ 0.75% TREO, or

·    5m intersect ≥ 1% Nb2O5, or

·    5m intersect ≥ 1% Ta2O5.

·          Expiry date: 5 years from the date of issue.

NEXT STEPS

Over the coming weeks and months, New Frontier Minerals will:

·     Continue field investigations to define priority drilling targets at the Cusp, Bobs, Paddington, Westminster, Old Trafford and Headingly Prospects.

·    Advance regulatory approvals and evaluate quotes from drilling contractors to prepare for the maiden Reverse Circulation (RC) drilling campaign in Q3 FY25.

New Frontier remains committed to delivering value to shareholders through disciplined exploration and development of its key assets.
