The company owns 100 percent of the only lithium-boron deposit in North America and one of two known lithium-boron deposits globally.

Inside Billionaire Gina Rinehart's Key Mining Investments

Australian billionaire Gina Rinehart has become a formidable force in the global mining industry.

After taking the helm of her father’s iron ore firm Hancock Prospecting in 1993, she embarked upon a diversification strategy that has vastly expanded her resource empire. Now Australia’s richest person, Rinehart has investments in many of the world’s most strategic commodities such as lithium, rare earths, copper, potash and natural gas.

Lithium Africa CEO Makes Case for Lithium Investing Amid Bear Market

"Shortly after that, they followed on with a big, multibillion-dollar investment in Chile. Again, the commodity they picked was lithium."

Macroeconomic and policy shifts in 2025 are creating ideal conditions for those willing to look past the headlines. While volatility in lithium prices has tempered short-term sentiment, the underlying demand trajectory remains strong. With governments reshaping supply chains to reduce reliance on China and accelerate the energy transition, lithium is emerging not only as a critical resource, but as a strategic investment theme with long-term upside.
