Key points

  • Hancock Prospecting, Gina Rinehart's private company, agreed on September 15th, 2026 to buy 515,791,601 new White Cliff Minerals (WCMLF) shares at A$0.017 each, about A$8.8 million (US$6.3 million). That is 13.5% of the copper explorer once the shares are issued.
  • Her estranged eldest son, John Hancock, sits on White Cliff's board and has been its largest shareholder, with about 6.8% voting power at his last substantial-holder notice. His mother's stake will be roughly double that.
  • White Cliff shares rose as much as 26.5% in one session, to A$0.022, and closed at A$0.019, up 11.8% on the day.

The money goes to the Rae copper project in Nunavut, Canada, where White Cliff has been drilling high-grade hits at deposits it calls Danvers 1, 2 and 3. The placement needs shareholder approval at an extraordinary general meeting expected on or about October 19th, 2026, with completion three business days later. Perth-based White Cliff is listed on the ASX as WCN and trades over the counter in the United States as WCMLF.

A family with history

Rinehart is Australia's richest person, and the family's disputes have run through the courts for more than a decade. Hancock and his sister Bianca sued their mother in 2011 over the Hope Margaret Hancock Trust, set up by their grandfather Lang Hancock in 1988 and holding a 23.4% slice of Hancock Prospecting. A New South Wales Supreme Court judge appointed Bianca Rinehart trustee in 2015.

John Hancock came to White Cliff as a strategic adviser in 2024, built his stake through open-market purchases and capital raisings, and joined the board as a non-executive director on August 1st, 2025. "White Cliff's first mover advantage led to my involvement as Strategic Advisor and then via on-market purchases and the capital raises, to become the Company's largest shareholder," he said. The Australian Financial Review reported the deal as a mother buying into the company her estranged son had backed first.

What the money buys

Managing director Troy Whittaker called the investment "a major milestone for White Cliff" and a validation of the company's work at Rae. "The search for large, high-quality new copper discoveries has rarely been more important," he said. The proceeds fund denser drilling at Danvers 1 toward a maiden resource estimate, step-out holes at Danvers 2 and 3, an airborne geophysical survey and follow-up at regional targets.

Hole DAN26036 at Danvers 3 returned 23 meters at 6.18% copper, including 3.9 meters at 16.45%, and earlier drilling at Danvers hit 175 meters at 2.50% copper with 8.66 grams per tonne of silver. White Cliff has not yet published a resource estimate.

The explorer held A$8.34 million in cash on June 30th, 2026 and spent A$2.18 million on exploration in the June quarter, so the placement roughly doubles its funding. The A$0.017 price matched the last close rather than offering a discount. At Tuesday's A$0.019 close, the shares Hancock Prospecting agreed to buy were already worth about A$9.8 million, a paper gain of roughly A$1 million before the vote.

Once the placement completes, Hancock Prospecting becomes White Cliff's largest holder, ahead of the son who built the position first. White Cliff files director dealings with the ASX rather than SEC Form 4s, so it sits outside the Form 4 record InsiderBuying.com reviews and carries no Insider Score. Company data is on the White Cliff Minerals page. Insider Access members track real-time insider activity across the copper names that do file Form 4s.
