Orion Resource Partners: $2.2 Billion Fundraise Brings AUM Above $9 Billion

By Amit Chowdhry • Mar 16, 2026

Orion Resource Partners LP, a global investment firm focused on metals and materials, announced the final close of its Mine Finance Fund IV at approximately $2.2 billion, marking the largest fundraise in the firm’s history and bringing total assets under management to well over $9 billion.

Fund IV is Orion’s flagship strategy aimed at financing the construction and acquisition of strategic metals and critical mineral assets. The fund drew commitments from a diverse global investor base, including pension funds, sovereign wealth funds, and institutional investors. It is already 61% committed across projects spanning North and South America, Europe, Australasia, and Africa, with early distributions signaling strong performance.

The fundraiser caps a period of significant expansion for Orion, driven by multiple strategic initiatives. These include the launch of the Orion Critical Mineral Consortium with $1.8 billion in committed capital in partnership with the U.S. government, a $1.2 billion joint venture with ADQ to establish Orion Abu Dhabi, and a collaboration with SNB Capital to support Saudi Arabia’s mining sector. The firm has also expanded its liquid strategies to more than $750 million in assets and launched Orion Industrial Ventures with a $43 million inaugural fund targeting emerging technologies in the critical minerals and energy sectors.

Together, these initiatives reflect Orion’s growing role across the metals and mining value chain, spanning private and public markets, royalties, mine finance, venture capital, and physical offtake and logistics. The firm continues to position itself around long-term trends such as decarbonization, constrained resource supply, and increasing global demand for critical minerals like copper and lithium.

KEY QUOTES:

“The past year has been a defining one for Orion. As global demand for critical minerals and strategic metals has continued to accelerate, we have seen growing engagement from sovereign investors and strategic partners who recognize the strength of our platform and our long-standing capabilities across the mining and metals value chain. The momentum we have achieved across all of our strategies reflects the consistency of our performance, the discipline of our approach, and the increasing relevance of our investment model in a rapidly evolving global landscape. Surpassing well over $9 billion in assets under management is a clear signal of that confidence and a meaningful milestone for the firm.”
