Australia just made it very clear: if you’re a China-linked investor in the country’s critical minerals sector, your shareholder rights are not guaranteed. Treasurer Jim Chalmers issued an interim order restricting voting and transfer rights for 361.5 million shares in Northern Minerals Ltd., held by Hong Kong-based entity Ying Tak.

Those shares represent roughly 3.8% of the ASX-listed company. The restriction means Ying Tak can’t vote at the company’s upcoming annual general meeting, and it can’t sell the shares either.

Why rare earths matter to everyone, including crypto

Northern Minerals operates the Browns Range heavy rare earths project in Western Australia. Heavy rare earths are the ingredients behind high-performance magnets used in electric vehicles, wind turbines, and defense systems. They’re also essential components in the semiconductor supply chains that underpin everything from AI data centers to the mining hardware that secures proof-of-work blockchains like Bitcoin.

The Chalmers order landed because Australian authorities suspect these shares were transferred in violation of a 2024 divestment directive. That earlier order specifically targeted Chinese investors who had been increasing their stakes in Northern Minerals without proper approval. The Foreign Investment Review Board is now investigating whether the transfers broke the rules.

This isn’t Canberra’s first move against Chinese ownership in the company. In 2023, the government blocked a stake increase attempt by the Yuxiao Fund. In 2024, five entities were ordered to divest 613.6 million shares, roughly 10.4% of the company. One investor who didn’t comply was hit with a A$14 million fine.

Then in May 2026, the government escalated further, ordering six additional China-linked investors to divest a combined 17.58% of Northern Minerals by July 2, 2026. As of July 8, a majority of those shares remained unsold. Analyst Matthew Hope noted that preventing voting is essentially a preliminary step, and that achieving full divestment to unrelated parties has proven genuinely difficult.

The bigger geopolitical picture

Australia has positioned itself as a potential alternative supplier to China in the rare earths market. The country holds significant deposits, and projects like Browns Range are central to that ambition. But as the Northern Minerals saga shows, building non-Chinese supply chains is complicated when Chinese investors already hold significant positions in the companies developing those very deposits.

What this means for investors

The immediate market impact is worth watching closely. Northern Minerals’ share price faces potential volatility as the forced divestment process continues. When governments order large blocks of shares to be sold by a deadline, and those shares remain unsold past that deadline, it creates an overhang.

The fact that a majority of the ordered divestments remain incomplete past their deadline tells you something important about liquidity. Finding buyers for large blocks of shares in a mid-cap mining company, while the government is actively scrutinizing the ownership structure, is not exactly a seller’s market. The A$14 million fine levied against one non-compliant investor in 2024 shows Canberra is willing to use financial penalties, but penalties alone haven’t solved the problem.
