Gina Rinehart's Hancock Prospecting is sitting on an estimated A$680 million paper loss on its rare-earth shares over the past year. Most of it comes from MP Materials, even though the company's revenue and output have grown sharply.
At a glance
- MP Materials accounts for roughly two-thirds of Hancock's estimated A$680 million rare-earths paper loss.
- Hancock's 8.4% stake in MP Materials is valued at about $834 million.
- Lynas posted record revenue of A$977.9 million in its 2026 financial year, yet its shares still fell.
Background
Hancock Prospecting is Gina Rinehart's private company, built on iron ore mining in Western Australia. It has put about $4 billion into critical minerals, buying stakes in rare-earth producers such as MP Materials in the US and Lynas Rare Earths in Australia. A paper loss is a fall in the market value of shares that have not been sold.
What happened
Hancock Prospecting has absorbed an estimated A$680 million paper loss on its rare-earth holdings over the past 12 months, the Australian Financial Review reported. The biggest drag is MP Materials, America's main rare-earth producer, which accounts for roughly two-thirds of the loss.
Hancock owns 8.4% of MP Materials, a stake worth about $834 million. Its other rare-earth holdings include Lynas Rare Earths, the largest producer outside China.
Why the shares fell
The losses do not reflect weaker businesses. MP Materials grew revenue 89% from a year earlier and lifted production of neodymium-praseodymium (NdPr), the key magnet material, by 41%. Investors still marked the stock down over execution risk and the heavy spending its expansion requires.
Lynas tells a similar story. It posted record revenue of A$977.9 million and a net profit of A$222.4 million in its 2026 financial year. Investors punished it anyway for production misses, ore-quality problems and rising costs on its heavy rare-earths expansion.
What it means
Hancock's loss shows how hard it is for investors to make money from the West's push to build rare-earth supply outside China. Governments want new mines and refineries, but the companies building them face long, costly ramp-ups that markets are quick to punish.
Hancock says it is not changing course. "Our investments in companies with projects yet to be developed take a long-term view," the company said. Its patience matters, because rare-earth developers depend on investors willing to hold through years of spending before production pays off.
Our read
Outlook: neutral. Share price losses for investors do not change how much NdPr is produced or used. The story reflects market sentiment toward rare-earth companies, not the metal's supply.
What to watch
- Whether Lynas fixes the production and ore-quality problems that weighed on its shares.
- MP Materials' progress on its expansion, which drove most of Hancock's loss.
- Any change in Hancock's stakes in rare-earth companies after the loss.

Detailed analysis
Supply Drivers
MP Materials lifted NdPr output 41%, adding rare-earth supply outside China despite its falling share price.
Mining Production
Lynas faced production misses and ore-quality problems, which slowed non-Chinese heavy rare-earth supply.
What could lift prices
- Rising NdPr output at MP Materials and record revenue at Lynas show non-Chinese supply is growing.
- Long-term investors like Hancock are holding their stakes rather than selling.
What could weigh on prices
- Weak share prices make it harder for rare-earth developers to raise new capital.
- Cost overruns at Lynas show how expensive new heavy rare-earth capacity can be.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Australia | Medium | Lynas and Hancock are central to Australia's plan to build rare-earth supply outside China. |
| United States | Medium | MP Materials is America's main rare-earth producer and drove most of the loss. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Critical Minerals Mining | Negative | Falling valuations make funding new rare-earth projects harder. |
Who gains, who loses
- New investors in rare-earth stocks: Lower share prices let them buy into growing producers more cheaply.
- Hancock Prospecting: Its rare-earth portfolio has lost an estimated A$680 million in market value over a year.
Other ways this could play out
- If MP Materials and Lynas deliver on their expansions, the paper losses could reverse.
- If costs keep rising, investors could stay cautious on rare-earth stocks for longer.
Price risks
- A fresh round of Chinese export curbs could lift rare-earth stocks quickly.
- Further delays at Lynas could deepen losses for its shareholders.
