Hancock Prospecting Diversifies into Strategic Metals and Rare Earths

Gina Rinehart's Hancock Prospecting has completed a strategic pivot away from its core iron ore business, disclosing nine new investments in mining and metals over the past twelve months. The portfolio expansion targets critical minerals such as rare earths, copper, gallium, and antimony, aiming to secure exposure to resources vital for defense and advanced manufacturing in Western economies.

The most recent transaction involves an A$8.77 million investment in White Cliff Minerals, granting Hancock a 13.5% stake in the Australian explorer. This move provides direct exposure to the Rae copper project in Nunavut, Canada, and follows a series of deals that have broadened the company's footprint beyond the commodity that established Rinehart as one of the world's wealthiest individuals.

Rare earths portfolio expands significantly

Hancock has aggressively increased its holdings in rare earth producers to diversify its revenue streams. In October 2025, the company committed A$125 million to Arafura Rare Earths, raising its interest to approximately 15.7% in the development of the Nolans project in Australia's Northern Territory. Simultaneously, Hancock invested A$22.5 million in St George Mining, securing a 6.24% stake in the Araxá rare earths and niobium project in Brazil.

This global expansion includes a US-based position in Rare Earths Americas, where Hancock holds 1.25 million shares valued at approximately $22.8 million. These acquisitions complement existing positions in MP Materials and Lynas Rare Earths, creating a comprehensive exposure to the emerging ex-China supply chain for critical minerals.

Strategic metals and defense exposure

Beyond rare earths, Hancock has integrated strategic metals into its investment thesis. In July, the company committed A$7.95 million to G50 Corp., acquiring a 5.4% stake to support drilling and gallium metallurgical testing at the Golconda project in Arizona. This addition introduces another critical mineral to the portfolio, further diversifying away from single-commodity reliance.

The strategy also extends into defense and technology sectors. A May regulatory filing revealed a $133 million pivot into defense contractors, including Lockheed Martin, Northrop Grumman, and RTX. Additionally, Hancock increased its stake in copper producer Hudbay Minerals by 10% while selling its holding in Chilean lithium producer SQM, signaling a rebalancing toward a broader set of strategic commodities rather than a withdrawal from battery minerals.

Copper investment drives exploration

The investment in White Cliff Minerals is designed to accelerate exploration activities at the Rae copper project. The capital will fund drilling efforts aimed at expanding the Danvers discoveries and testing regional targets across the Nunavut property. This transaction, which is pending shareholder approval, underscores the company's commitment to securing high-grade copper resources in North America.

These moves align with the broader market trends highlighted by GN auto stocks/materials: rare earths, where supply chain security is a primary driver for institutional capital. By diversifying into multiple critical mineral producers and defense contractors, Hancock Prospecting is positioning itself to benefit from long-term structural demand for strategic resources.
