Metallurgical Testwork at Pomme REE Project

New Frontier Minerals Ltd (LSE and ASX: NFM) is pleased to announce that it will commence characterisation and metallurgical studies at the Pomme REE Project, which is located approximately 500 km northwest of Montréal in Québec. Initial activities will focus on conventional metallurgical testwork, followed by Metallium Limited's proprietary Flash Joule Heating (FJH) testwork on existing drill samples to assess the potential to upgrade REE mineralisation. This testing will target the mid-to-high-grade zones of REE mineralisation identified during previous scout drilling.

Highlights:

• Metallurgical testwork aims to establish a pathway to produce higher-grade REE concentrates and could represent a key catalyst in unlocking the economic potential of the Pomme Project
• Initial activities will target conventional metallurgical testwork followed up with Flash Joule Heating (FJH) testwork on existing drill samples to assess the potential for upgrading REE mineralisation
• Testing will target key intercepts including mid-high-grade zones of REE mineralisation that has been identified by previous scout drilling2

Chairman Gerrard Hall commented: "Commencing characterisation and metallurgical studies marks an important step forward at Pomme. Historical drilling has already confirmed the scale and continuity of this large, carbonatite hosted REE system, and our focus now turns to understanding how the mineralisation responds to processing. The inclusion of Flash Joule Heating testwork alongside conventional methods reflects our commitment to identifying the most effective pathway to upgrade REE mineralisation. Together with Metallium as our processing and technology partner, we believe this work will help unlock Pomme's potential and deliver meaningful value for shareholders."

POMME CARBONATITE DEVELOPMENT STRATEGY

The proposed work program will focus on conventional metallurgical testwork with follow up Metallium Limited's proprietary Flash Joule Heating (FJH) technology to existing drill core samples, targeting the production of upgraded rare earth concentrates and early validation of a scalable, low-cost processing pathway that has the potential to materially enhance project economics1.

Samples from drill holes POM-23-03, POM 23-01 and POM 23-07 to the southwest of the mineralised carbonatite returned broad mineralised intervals with multiple high-grade TREO intersections and will be considered for the first phase of characterisation and metallurgical testwork2 (Figure 1).

The historic work program has significantly advanced the geological understanding of the complex, with early interpretations indicating that higher-grade mineralisation occurs within a ring structure surrounding a magnetic ultramafic carbonatite core.

Importantly, large portions of this prospective ring structure remain untested due to the broad drill spacing, presenting clear potential for further discovery through follow-up drilling.

POMME CARBONATITE REE PROJECT BACKGROUND

The Project is located approximately 500 km northwest of Montréal in Québec, around 100 km from the service town of Lebel-sur-Quévillon, approximately 50 km west of the Waswanipi Cree First Nation community, and benefits from easy access via established logging roads (Figure 1)2. The Project comprises 43 mineral claims, covering approximately 2,400 ha area and is located 7km from the world class Montviel Deposit which has a total Indicated and Inferred resource of 266 Mt @ 1.46% TREO and 0.14% Nb2O5.2

MTM Critical Metals (a 100% subsidiary of ASX:MTM) has completed a 13-hole diamond drilling program totalling approximately 5,718 metres at its Pomme Rare Earth and Niobium Project in Québec, Canada2. Carbonatite-hosted REE-Nb mineralisation was intersected in every drill hole, confirming the presence of a large, laterally extensive mineralised system exceeding 2 km² that remains open at depth (Figure 1).

The Pomme Project provides NFM with a highly capital-efficient, low-risk entry into a strategically located Canadian rare earth asset via a two-year option structure requiring upfront consideration of A$100,000 in cash (paid) and A$200,000 in NFM shares (issued) and minimum annual expenditure of A$100,000 per annum during the option period. This staged earn-in framework enables NFM to progressively earn a majority (90%) interest through defined technical and investment milestones, significantly limiting upfront capital exposure while preserving substantial upside1.

NEXT STEPS

Preliminary metallurgical testwork

• Existing sample diamond drill core will be used for characterisation studies and metallurgical assessment utilising conventional metallurgical testwork as well as tailored Metallium Limited's proprietary Flash Joule Heating (FJH) processing technology to beneficiate and upgrade REE sample.
