Gina Rinehart: From Iron Ore Heiress to Rare-Earth Power Broker
Gina Rinehart, often recognized as Australia’s richest individual, has spent decades transforming a family inheritance into a global mining empire. More recently, she has strategically expanded into the rare-earth sector, positioning herself at the intersection of finance, technology, and geopolitics.
A Mining Legacy Rooted in Iron Ore
Rinehart’s story begins in Western Australia, where she inherited Hancock Prospecting from her father, Lang Hancock. Under her leadership, the company grew into one of Australia’s most influential private mining businesses. While iron ore remains its cornerstone, Rinehart has diversified the business into agriculture and other natural resources, demonstrating a vision that extends far beyond any single commodity.
Her ability to balance legacy wealth with strategic expansion has been key to her sustained success. By combining operational expertise with long-term planning, she has ensured that Hancock Prospecting remains a dominant player in Australia’s resource sector.
Venturing into Rare Earths
In recent years, Rinehart has turned her focus to rare-earth elements, minerals that are essential for electronics, clean energy, and defence technologies. Her investments in this sector have grown significantly, with her portfolio expanding from approximately US$800 million to US$2.69 billion.
A pivotal move came in November 2025, when Hancock Prospecting became the top shareholder of MP Materials, the United States’ only integrated rare-earth mining and processing company. Rinehart’s 8.4 percent stake, valued at nearly US$1 billion, places her at the center of a critical supply chain. Beyond MP Materials, she has increased her stake in Arafura Rare Earths to 15.7 percent and maintains holdings in other major players like Lynas.
These investments are not just financially motivated. They give Rinehart influence over a sector that is becoming increasingly strategic on a global scale. By aligning with Western supply chains for rare-earth minerals, she is positioning herself at the heart of a geopolitical and technological shift.
Strategic Influence and Global Reach
Rinehart’s involvement in rare-earths extends her influence beyond Australia. MP Materials’ Mountain Pass mine is a crucial asset for the United States, and her stake connects her business directly to the security of the Western supply chain.
Her actions reflect a broader trend: governments and investors are prioritizing secure sources of critical minerals. Rinehart’s strategic investments allow her to operate at the intersection of business and policy, giving her unique leverage in shaping an industry that is vital to modern economies.
The Scale of Her Wealth
Rinehart’s rare-earth holdings are just one component of her vast fortune. Hancock Prospecting held around US$3 billion in U.S.-listed stocks and ETFs as of September 2025, with MP Materials representing her largest single U.S. position. Combined with her mining, agricultural, and other business interests, her net worth is estimated at approximately US$32.3 billion.
Her story is about more than wealth; it is about foresight and influence. Rinehart is building an empire that spans traditional mining and next-generation critical resources. She is shaping supply chains that will underpin the world’s green technologies and defence capabilities. Her investments have implications not only for her own wealth but also for global markets and industrial strategy.

What Comes Next
Looking ahead, Rinehart is likely to continue expanding her rare-earth portfolio. She already holds significant stakes in companies outside China, positioning herself as a major non-Chinese supplier of these vital minerals. With governments seeking to secure critical resources, her influence is expected to grow.
Her career demonstrates a blend of vision, strategy, and calculated risk-taking. For aspiring business leaders, Rinehart’s trajectory offers lessons in combining legacy assets with forward-looking investments that respond to global trends.
