New Frontier Minerals Limited (ASX: NFM), formerly Castillo Copper, explores for copper in Queensland and for rare earths in the Northern Territory and Quebec. Its 100%-owned NWQ Copper Project in the Mt Isa copper belt hosts the Big One deposit, with a JORC 2012 Mineral Resource (28 February 2022) of 2.1 Mt at 1.1% Cu for 21,886 t of contained copper at a 0.45% Cu cut-off. Almost all of it is Inferred (2.1 Mt in situ, 21,800 t Cu); about 7,000 t of mine-dump material at 1.2% Cu (86 t Cu) is Indicated. NFM lodged a mining lease application for Big One in November 2025 and is assessing processing at Austral Resources' Mt Kelly plant under an MOU. No economic study has been published. Its rare-earth projects are Harts Range (heavy rare earths and niobium, Northern Territory) and the Pomme rare-earth and niobium project in Quebec, which it holds under an option to acquire 90%.

Lifecycle Milestones
Jurisdiction (40%)9/10
Queensland: Fraser PPI 2025 is 82.72 of 100 (rank 18 of 68), which maps to 9 on this site's scale. Its NWQ copper project (Big One deposit) is in Queensland's Mt Isa copper belt, with further ground in the Northern Territory, both Tier-1 Australian jurisdictions.
Infrastructure (40%)No verified figure
Researched with nothing found: no source we could cite confirms or rules out an existing mill, road access, grid power, or tailings facility at NWQ Copper Project (Big One Deposit), Mt Isa copper belt, Queensland, Australia (checked Oct 2, 2026; recheck due Mar 31, 2027). Counts at a neutral 5/10 until one does.
Nearby producing mine (20%)Not yet researched
No producing mine within 50 km in our reference list (nearest listed: Century (tailings retreatment) (Sibanye-Stillwater), 97 km). That list doesn't cover every mining district yet, so a longer distance isn't scored as remote.
Acquisition Susceptibility
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal in the research, a producer that already owns part of the company, is scored from its disclosed strategic shareholders. A producer that is a joint-venture or earn-in partner on the project, rather than a shareholder, isn't captured yet.
How this score is built
- Disclosed pending dealSub-score: Not scored
No pending acquisition or merger disclosed (checked)
Not scored: having no deal in flight isn't held against a company.
Weight 26.25% - Producer's strategic stakeSub-score: Not scored
No producer holds a disclosed stake on file (holder register researched) See holders
Not scored: most juniors that do get bought had no prior toehold, so a missing stake says little either way.
