Shares of Mineral Resources Limited plunged Friday after founder and managing director Chris Ellison unloaded A$122.5 million worth of stock in the lithium, iron ore and mining services outfit. The move once again threw the high-profile Australian miner into the governance spotlight. According to Reuters, cited by Mining Weekly, the stock dropped as much as 7.1% in early trading following the announcement.
That’s the issue here. While MinRes has been working to steer attention toward debt paydown, firmer lithium prices, and the Onslow Iron ramp, its biggest shareholder’s hefty sell-off throws that narrative off course.
This move followed a strong rally. MarketIndex data had Mineral Resources finishing at A$64.77, down 7.7% on the day, but still up 145.3% for the year—a backdrop that throws the founder’s share sale into sharper relief, especially when set against the stock’s comeback rather than a lackluster longer-term chart.
According to the company’s Appendix 3Y filing, Ellison offloaded 1.75 million shares on-market from May 11 through May 14, fetching a weighted average of A$69.98 per share. MinRes cited “personal financial planning purposes”—among them, a family office and a private wealth vehicle—as the reason for the sale, adding the transaction complied with its securities trading policy.
Ellison is still the company’s top shareholder, holding 20,834,661 shares, or 10.54% of issued capital, according to the filing. December 2017 was the last time he sold MinRes shares.
No lift from the wider market—S&P/ASX 200 slipped 0.12% Friday, with materials names down 2.85%. Miners BHP, Rio Tinto, and Fortescue all finished lower as the sector weakened. Mineral Resources took a sharper hit, tracing losses back to the Ellison disclosure.
The company’s been putting more on the table for investors. In its April 30 quarterly update, MinRes bumped up FY26 volume guidance for mining services, Onslow Iron, Wodgina, and Mt Marion. Liquidity now sits at A$1.8 billion, and net debt has edged down to roughly A$4.5 billion.
On the April 30 call, Chief Financial Officer Mark Wilson told analysts Onslow Iron was “generating free cash” and chipping away at debt. Balance sheet strength comes first, he said, then the focus shifts to selective high-return brownfield growth.
MinRes’ balance-sheet strategy partly hinges on its lithium stake sale to South Korea’s POSCO. Back in November, Reuters reported POSCO was set to pay $765 million for a 30% slice of MinRes’ lithium unit. RBC Capital’s Kaan Peker, in a note at the time, said the transaction “validates the quality” of MinRes’ lithium assets and adds muscle to the company’s balance sheet. Reuters
The risks here aren’t minor. Back in April, MinRes flagged that diesel prices had already doubled since March. If those levels hold, the company projected June-quarter costs could jump by around A$4 per wet metric tonne for Onslow Iron, A$7 per wet metric tonne at the Pilbara Hub, and close to A$60 per dry metric tonne of SC6 at Wodgina and Mt Marion. SC6 refers to spodumene concentrate standardized to 6% lithium oxide, which is the typical metric for lithium sales.
Then there’s the governance headache. Back in 2024, Reuters reported that MinRes confirmed Ellison would step down within 18 months, following a board investigation that found he’d misused company resources for personal gain and dodged taxes. Analysts, according to the same piece, knocked the drawn-out handover plan.
The filing doesn’t indicate any policy violation. Still, the market’s response tells a different story—investors remain quick to react to anything that might hint at a shift in Ellison’s established relationship with Mineral Resources. Next up: Onslow shipments, lithium prices, POSCO’s completion, and whatever new signals emerge on leadership.
