Key Highlights:

  • VHM has secured the final approval for its Goschen rare earths and mineral sands project in Victoria and refreshed its feasibility study, but the shares were trading in the low 20-cent range in late September, far below their October 2025 peak.
  • Ardea's Kalgoorlie Nickel Project remains waiting on a definitive feasibility study that has been delayed, while nickel prices stay subdued.
  • For both, outperformance would likely need binding finance and a clear Final Investment Decision (FID) pathway, not just positive studies.
  • Upcoming company updates and execution against stated plans remain central to the next phase for both stocks.

Neither VHM nor Ardea Resources sits in the S&P/ASX 200, and both pre-revenue critical minerals developers trade well below their 52-week highs. To close that gap, each most likely needs to turn a long-dated project into a funded, construction-ready asset.

A tough benchmark for pre-revenue developers

The S&P/ASX 200 closed down 0.72% at 8,702 points on 24 September, as Brent Crude traded above US$100 a barrel, US bond yields rose and investors braced for the Reserve Bank's 29 September decision, with markets pricing a strong chance of a rate hike.

That backdrop matters for developers like VHM and Ardea, whose value sits in cash flows that are years away. Higher rates and bond yields reduce what investors will pay for them today. the materials sector rose 12.22% in August against 1.54% for the S&P/ASX 200, but that rally was driven mainly by gold and uranium, not rare earths or nickel.

Neither company is an index member, so the S&P/ASX 200 is used here only as a benchmark.

VHM (ASX:VHM): approvals done, funding next

VHM is developing the Goschen project in north-west Victoria, which is designed to produce a rare earth concentrate containing magnet metals neodymium-praseodymium (NdPr), dysprosium and terbium, plus a zircon-titania heavy mineral concentrate.

On 4 September, the Victorian Planning Minister approved a planning scheme amendment covering off-site infrastructure, which as the last of six regulatory approvals. Days later, VHM released a refreshed definitive feasibility study (DFS). As reported by Small Caps, it outlined a pre-tax NPV of A$807 million at an 8% discount rate, a 33% internal rate of return and a three-year payback. The study assumed an 18-year mine life at 5 million tonnes a year, execution Capital of A$283 million and total funding needs of A$482 million.

Iluka Resources is central to the plan. It has signed a binding take-and-pay offtake agreement for Goschen's rare earth concentrate to feed its Eneabba refinery and committed A$40 million in cornerstone funding. Export Finance Australia has conditionally offered up to A$75 million, and the US Export-Import Bank has issued a letter of interest for up to US$200 million. Both of those are conditional and non-binding.

The share price tells a more cautious story. VHM at A$0.21 on 18 September, around 76% below its 52-week high of A$0.86 in October 2025, and gave its Market Value as about A$65 million. the stock at A$0.24 on 25 September and pointed to pressure from an extended US-China trade truce and rising bond yields. With a large funding requirement against a small market capitalisation, the market appears to be pricing in dilution risk.

Ardea Resources (ASX:ARL): a giant nickel resource in a surplus market

Ardea's Kalgoorlie Nickel Project in Western Australia includes the Goongarrie Hub, being studied in a joint venture with Sumitomo Metal Mining and Mitsubishi Corporation. According to Ardea's June 2026 quarterly report, the consortium has earned a 35% interest and can increase it to 50% on a positive FID. It is also funding the DFS under an A$98.5 million budget, of which about A$84.5 million had been spent by 31 May.

The DFS has repeatedly slipped. It was meant to finish by 30 June 2026, but the partners are now pursuing optimisation work. Ardea said it expects to give the market an update before the end of October 2026 and to lodge its environmental approval documents in the December quarter. It held A$18.3 million in cash at 30 June and had no debt.

On the financing side, Ardea said on 5 February 2026 that Export Finance Australia had provided conditional, non-binding support of A$500 million and US EXIM support of US$350 million.

Nickel prices are the main obstacle. LME nickel near US$16,570 a tonne on 1 September, with refined Supply still plentiful despite Indonesian ore Quota cuts. Ardea's last traded price that could be confirmed was around A$0.43 in July, near the bottom of a 52-week range of roughly A$0.385 to A$0.77. When checked for this article, the stock as halted, so investors should check the ASX platform for any announcement.

What links the two, and where they differ

Each has a major industry partner (Iluka for VHM, the Japanese consortium for Ardea) and conditional support from Export Finance Australia and US EXIM, reflecting efforts by Canberra and Washington to build critical minerals supply chains outside China.

The differences are scale and timing. Goschen is a relatively modest project with its approvals and a refreshed DFS in hand, so its next hurdle is financial close. The Kalgoorlie Nickel Project is a multi-decade, high-pressure acid leach development that still needs a completed DFS in a nickel market many analysts expect to stay in surplus. VHM's risk is mainly financing and dilution, while Ardea's is whether the project works at current prices.

What investors could watch next

RBA decision (29 September): a rate hike could weigh further on long-dated developers.

VHM financial close: lender due diligence, heavy mineral concentrate offtake and any Equity component of the A$482 million package.

Iluka's Eneabba refinery: commissioning is targeted for 2027 and underpins Goschen's offtake.

Ardea's October update: the promised DFS progress update and any reason for a trading halt.

Commodity prices: NdPr and dysprosium prices, US-China trade developments, and whether LME nickel stocks fall below 250,000 tonnes, a level Crux flagged.

The bottom line

For VHM, outperforming the S&P/ASX 200 probably rests on turning A$807 million of study NPV into a funded project without heavy dilution. For Ardea, it depends on the DFS landing with Economics that its partners and lenders will back, in a nickel market that has given little help. Both have strong partners, but both still need to deliver funding and final decisions.
