New Frontier Minerals Limited (ASX: NFM ) (“ New Frontier ”) is pleased to provide the following operations update across its core projects, which include the NWQ Copper Project in Queensland, the Harts Range Heavy Rare Earths and Niobium Project in the Northern Territory, and the Pomme Rare Earth Element and Niobium Project in Québec, Canada.

Importantly, the Mining Lease Application (MLA) for the Big One Copper Deposit has successfully passed through the initial regulatory review and received technical assessment approval from the Queensland Natural Resources and Mines Department - a critical milestone in advancing the project toward potential near-term production.

NEW FRONTIER CHAIRMAN GERRARD HALL COMMENTED “New Frontier continues to advance its diversified portfolio of critical minerals projects, with the strengthening outlook for copper highlighting the strategic importance of the NWQ Copper Project. New Frontier will accelerate activities at the NWQ Project, which includes the Mining Lease Application at the Big One Copper Deposit, which has now received technical assessment approval, marking an important step toward potential near-term copper production utilising Austral Resources’ Mt Kelly Processing Facility. With a strong working capital position of approximately A$2.62 million and additional funding expected from grants and R&D rebates, New Frontier is well positioned to advance its key projects.

MINING LEASE APPLICATION – TECHNICAL ASSESSMENT APPROVED

The Big One Deposit hosts a JORC-compliant Mineral Resource Estimate of 2.1Mt @ 1.1% Cu (21,886t contained copper).[1] Surface (indicated) stockpiles of 7,400t @ 1.2% Cu[1] have been identified, supporting a low-strip, near surface development opportunity. NFM is specifically targeting additional stockpile material and mineralisation from 0 to 50m depth, where the high-grade near-surface copper zones are concentrated.

Subject to regulatory approvals, the Initial Development Plan proposes open-cut mining of near-surface copper mineralisation and transport of existing historical stockpiles to the Mt Kelly Processing Facility, operated by Austral Resources Ltd (ASX: AR1), under the existing Memorandum of Understanding.

COPPER STOCKPILES AND HISTORICAL INTERCEPTS

Selective grab sampling of the historical ex-mine stockpiles has returned copper grades ranging from 3.9% to 11.85% Cu, confirming the high-grade nature of near-surface mineralisation. Sulphuric acid leach testwork on these stockpile materials delivered indicative copper recoveries of up to 99%, supporting a conventional acid leach processing pathway at the Mt Kelly facility .[4]

The best historical drill intercepts from the Big One Deposit, which highlight the exceptional copper grade potential within the 0–50m target zone, include:

• BH 303RC: 40m @ 1.64% Cu from surface, including 11m @ 4.40% Cu from 24m, 5m @ 7.34% Cu from 28m, and 1m @ 16.65% Cu from 29m[3]

• BH 301RC: 44m @ 1.19% Cu from surface, including 14m @ 3.55% Cu from 27m, 3m @ 10.88% Cu from 37m, and 1m @ 12.6% Cu from 37m[3]

• BH BO017: 34m @ 1.51% Cu from surface, including 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[3]

These intercepts demonstrate the potential for very high-grade copper up to 28.4% Cu[2] in bonanza-grade intervals within the targeted 0–50m near-surface mining zone. Further, planned, resource drilling is expected to extend known mineralisation at the Big One Deposit to target both oxide and sulphide copper.

COPPER MARKET THEMATIC

NFM’s NWQ Copper Project sits within this highly favourable macro backdrop. The Big One Deposit, located in the historical copper region of Mt Isa is one of the world’s premier copper districts, in proximity to established major mining operations and hosts a JORC-compliant Inferred Mineral Resource of 2.1Mt @1.1% Cu, with near-surface, high-grade mineralisation targeted for near-term production.

The combination of record copper prices, a tightening global supply outlook, and NFM’s advanced development pathway positions New Frontier well to benefit from copper’s strengthening fundamentals.

Record Prices and a Tightening Market

Copper is experiencing a structural rerating. In 2025, the London Metal Exchange (LME) copper price surged approximately 40%, its strongest annual performance since 2009.[5]

Prices reached an intra-year peak of US$12,960/t on the LME and US$14,527.50/t on COMEX in January 2026.[6] Major investment banks have markedly upgraded their price outlooks: J.P. Morgan projects copper to average approximately US$12,075/t in 2026,[7] while Goldman Sachs forecasts the LME price will reach US$15,000/t by 2035.[8]

energy transition, electrification of transport, and the rapid build-out of artificial intelligence (AI) infrastructure. Electric vehicles (EVs) related copper demand is forecast to grow from approximately 2.3 million MT in 2025 to 6 million MT by 2035.[18] Grid upgrades and power infrastructure alone are projected to drive more than 60% of copper demand growth through to 2030.[8] Data centre copper demand is anticipated to reach approximately 475,000 MT in 2026, up approximately 110,000 MT year-on-year.[9] Bloomberg NEF’s Transition Metals Outlook 2025 projects that copper demand tied to the energy transition could triple by 2045, with the market potentially entering a structural deficit as early as 2026.[10]

The supply side of the copper market faces acute and worsening constraints. The International Copper Study Group (ICSG) forecasts refined copper use will grow 2.1% to 28.73 million MT in 2026, outpacing production growth and resulting in a market deficit of approximately 150,000 MT.[11] J.P. Morgan estimates the 2026 refined copper deficit at approximately 330,000 MT.[12] Three of the world’s ten largest copper mines - Grasberg (Indonesia), Kamoa-Kakula (DRC), and El Teniente (Chile) - experienced significant disruptions in 2025 and early 2026, collectively removing hundreds of thousands of tonnes from the anticipated supply outlook.[13] New mine development has a multi-year lead time, and without major new investment in mines and recycling, Bloomberg NEF estimates the cumulative supply deficit could reach 19 million tonnes by 2050.[14]

HARTS RANGE PROJECT

potential and ongoing evaluation of the remaining 40 geophysical targets identified by Southern Geoscience Consultants. These anomalies represent high-priority targets that require follow-up for prospectivity analysis and consideration for the next phase of exploration.

A key area of interest for the upcoming exploration phase is the Kings Cross Prospect, located in the southern part of tenement EL32513. Recent airborne geophysical surveys identified a prominent local magnetic anomaly at Kings Cross (507884 E, 7442739 N; GDA94, MGA Zone 53), with preliminary review of the magnetic data by Southern Geoscience Consultants reveals a large and prominent magnetic feature, approximately 150–200m in diameter and extending to 150–200m depth.

POMME REE-NIOBIUM PROJECT

New Frontier is planning to undertake metallurgical test work at the Pomme REE–Niobium Project, from existing diamond core for comprehensive testing by Metallium Ltd (ASX:MTM). The program will be a low-cost technical exercise to evaluate both conventional processing pathways and tailored testing using MTM’s proprietary Flash Joule Heating (FJH) technology, supporting mineralogical characterisation and optimisation of the processing pathway for the project, over which NFM holds an exclusive option to acquire up to 90%.
