What Appian Capital Advisory does
Appian Capital Advisory Limited is the investment advisor to the Appian Natural Resources private capital funds, a London-headquartered private capital platform focused exclusively on the metals and mining sector. The firm operates an integrated "investor-operator" model that pairs long-term equity capital and bespoke credit/royalty/stream capital with in-house technical teams spanning geology, mining engineering, metallurgy, processing, ESG and corporate finance. Appian pursues a "technical arbitrage" methodology — using its deep in-house technical bench to develop differentiated views on project economics and de-risking paths versus traditional financiers or external consultants — and actively runs portfolio companies through construction, ramp-up and steady-state operations.
The platform has two principal product lines. Equity Investments deploys long-term capital into small-to-medium-sized metals and mining companies from advanced exploration through production, with 12 mines brought into production since inception. The Credit & Royalties platform, led by Head of Credit & Royalties Tim Mister, originates bespoke senior secured debt, subordinated debt, convertible debt, preferred equity, royalties and streams, typically US$50-200 million per transaction, with notable deals including the US$450M Osisko Development Cariboo facility and the US$175M Asante Gold package. Atop the base business, Appian has launched the US$1 billion IFC-Appian Critical Minerals and Metals Fund (with the International Finance Corporation), a SAFE-Appian SCOR critical-minerals policy advisory committee, and a dedicated Critical Minerals division led by CEO Paulo Castellari.
Revenue is generated primarily through recurring management fees on approximately US$5.0 billion of assets under management (as of 10 October 2025), plus carried interest and capital gains on exits (16 to date, including the US$420M sale of Mineração Vale Verde to Baiyin Nonferrous and the A$418M OZ Minerals takeover of Avanco Resources), supplemented by royalty/stream income and one-off monetisations such as the US$170M sale to Versamet Royalties. Distribution is relationship-driven across 10 global offices (London, Dubai, New York, Belo Horizonte, Hong Kong, Toronto, Perth, Lima, Abu Dhabi, São Paulo), with deal flow sourced through direct senior-level engagement, industry conferences (e.g., Future Minerals Forum) and a dedicated credit & royalty origination desk.
