Orion Resource Partners

Oskar Lewnowski's Orion Resource Partners structures streaming and royalty investments in mining — from copper to lithium — for institutional capital.

Orion Resource Partners

Orion Resource Partners emerged in 2013 when Oskar Lewnowski, former head of Red Kite's mine finance group, launched an independent platform focused exclusively on the metals and mining sector. The firm established itself by offering bespoke capital solutions that traditional banks pulled back from after the 2012–2015 commodity downturn. Lewnowski brought deep structuring expertise and a network of operator relationships that allowed Orion to originate deals outside competitive auctions. The firm deploys capital across three primary instruments: metals streaming agreements, secured royalties, and mezzanine debt facilities. Orion typically commits $50–$200 million per transaction, targeting producing or near-producing mines rather than greenfield exploration. The strategy spans copper, gold, zinc, and battery metals such as lithium and nickel. Flagship investments include a gold stream on the Fruta del Norte mine in Ecuador (operated by Lundin Gold) and a silver stream on the Mantos Blancos copper mine in Chile (per public deal records, 2021–2023). Orion participates in both senior secured structures and structured equity, maintaining a preference for hard-asset collateral and offtake-linked returns. Geographic concentrations include the Americas, West Africa, and Australia. Headquartered in London with offices in New York and Denver, Orion manages several commingled funds alongside separately managed accounts for large institutional allocators. The firm counted approximately 70 employees across its three offices as of mid-2023 (per the firm's official communications). September 2023: Orion closed Orion Mine Finance Fund III at $2.1 billion in capital commitments, exceeding its original target and bringing total assets under management into the range reported above (per Bloomberg, September 2023). The firm also operates a separate royalties-focused vehicle, Orion Royalties, that acquires existing royalty portfolios and creates new streams. Orion's structural distinction is its deliberate avoidance of traditional equity fund structures for mine exposure. By transacting through streams and royalties — where repayment links to physical production volumes rather than share prices — the firm isolates commodity-price risk while underwriting operational performance. This architecture appeals to pension funds and endowments that want metals exposure but lack the in-house capability to diligence individual mine operators. The approach also means Orion competes less with private equity mining funds and more directly with dedicated royalty companies such as Franco-Nevada and Wheaton Precious Metals.

Frequently asked questions

How does Orion Resource Partners make money in mining without owning the mines?

Orion uses streaming agreements and royalties rather than equity. In a streaming deal, Orion provides an upfront cash payment to a mining operator in exchange for the right to purchase a percentage of future production at a fixed, below-market price. The operator uses the capital to build or expand the mine, and Orion receives physical metal it can sell at the prevailing spot price. The return depends on production volumes and metal prices, not the operator's share price. Royalties work similarly but convey a percentage of revenue or profits without an ongoing purchase obligation.

Who runs investment decisions at Orion?

Oskar Lewnowski serves as Chief Investment Officer and leads the investment committee. He built the mine finance group at Red Kite prior to founding Orion in 2013, giving him over two decades of specialized structuring experience in the metals sector. The broader investment team includes geologists, mine engineers, and structured-finance professionals split across London, Denver, and New York.

Does Orion participate in fund commitments or only direct deals?

Orion operates exclusively through direct, bilateral transactions with mining companies. The firm does not invest in third-party managed funds or act as a limited partner in other vehicles. Each investment is structured in-house by Orion's technical and financial teams, typically as a bespoke streaming agreement, royalty, or secured debt facility.

What metals does Orion focus on?

Orion's portfolio spans precious metals — primarily gold and silver — alongside base metals such as copper and zinc, and an increasing allocation to battery metals including lithium and nickel. The firm publicly states it avoids bulk commodities like iron ore and thermal coal, preferring metals with strong industrial demand drivers and limited substitution risk.

How is Orion Resource Partners different from Franco-Nevada or Wheaton Precious Metals?

Orion operates as a private investment manager raising closed-end funds and separately managed accounts, whereas Franco-Nevada and Wheaton are publicly traded royalty companies. Orion can structure more bespoke, credit-like instruments — including mezzanine debt and structured equity — that a public royalty company balance sheet typically cannot accommodate. Orion also deploys capital into development-stage assets more readily than the public royalty majors.

What investment stages does Orion typically target?

Orion focuses on producing or near-producing mines that require expansion capital, equipment financing, or balance-sheet restructuring. The firm generally avoids greenfield exploration due to the extended timeline and binary technical risk, though it will consider development-stage projects with a clear path to production and proven reserves. Its typical transaction size of $50–$200 million targets middle-market operators underserved by bank project-finance desks and too small for major-equity underwriters.

Does Orion maintain any philanthropic or ESG-linked investment structures?

Orion integrates ESG criteria into its underwriting process and requires operators to adhere to International Finance Corporation performance standards. However, the firm does not maintain a standalone philanthropic foundation or an explicit impact-investing mandate. Environmental and social compliance functions as a deal-screening requirement rather than a separate vehicle or allocation.
