Drill Targets Finalised at Harts Range Heavy Rare Earth and Niobium Project, NT

New Frontier Minerals Limited (LSE/ASX: NFM) is pleased to announce the maiden reverse circulation ("RC") drill program comprising up to 46 holes to test near surface mineralistion at the Harts Range Heavy Rare Earths Project, located 140km north-east of Alice Springs in the Northern Territory, Australia has been finalised.

Highlights

·    Maiden RC drill program comprising up to 46 holes to test surface mineralistion at the Harts Range Heavy Rare Earth and Niobium Project, NT, has now been finalised

·    Recent correspondence from the mining regulator indicates that approvals to commence the drilling campaign is imminent, and NFM's geological team is now back at site this week

·    Logistics planning is progressing well, with significant preparatory work already completed on site to reduce mobilisation lead time, with site works to commence following receipt of regulatory approvals

·    The campaign's focus is to understand the extent of heavy rare earth mineralisation, especially dysprosium and terbium, which are in strong demand for their key role in high-performance magnets

·    The Board believes insights from the drilling campaign has the potential to create significant value for shareholders

Chairman Gerrard Hall commented: "Finalising the drill targets for the upcoming campaign at the Harts Range Project marks another important milestone for NFM. Since acquiring the project in the last 12 months, the NFM geological team has completed systematic exploration activities and successfully identified numerous high-priority targets, which are now set to be drill-tested. The Board considers the delineation of these targets within only 12 months to be a significant achievement within what it believes is a highly compelling heavy rare earth system.

"Moreover, with near-surface mineralisation and a dominant proportion of high-value heavy rare earth lanthanides such as dysprosium and terbium, the Harts Range Project is uniquely positioned to potentially play a significant role in future global supply chains for critical minerals.

"The Board looks forward to the drilling campaign commencing and insights coming to hand, as they could potentially generate significant value for shareholders."

IMPENDING RC DRILLING CAMPAIGN

NFM's geological team is preparing logistics and readying to mobilise to site, as the Northern Territory's Department of Mines has indicated that final regulatory approvals to commence the drilling campaign is imminent.

The proposed reverse circulation (RC) drilling campaign will comprise up to 46 drill-holes for circa 2,500m to test the numerous prospects that have been identified from the exploration activities undertaken at Harts Range over the past 12 months (Figure 1). The program has been designed to test depth extensions to the near-surface zones of high-grade heavy rare earth and niobium mineralisation, identified from field campaigns.

The Harts Range Project continues to demonstrate its status as a unique heavy rare earths project, exhibiting high-grade mineralisation at surface and a consistently high proportion of critical magnet rare earth elements[1].

Notably, recent metallurgical test-work on a 25kg bulk sample returned a very high HREO/TREO ratio of 94.8%, confirming the dominance of key magnet rare earth elements dysprosium (Dy) and terbium (Tb) -both essential for high-performance permanent magnets, electric vehicles, and defence applications[2].

NFM is concurrently advancing studies into conventional and novel processing pathways for heavy rare earth-enriched material, with the objective of accelerating commercialisation and supporting future offtake discussions with global magnet supply-chain participants.
