Nairank Global Limited
About Nairank Global
Nairank Global is an independent mineral inspection, testing and due diligence firm operating across Africa. It checks mineral suppliers at the national registry and inspects and tests the goods at source, before the contract is signed. It verifies mineral suppliers, tests and assays gold, and inspects mines and warehouses for the buyers, refiners and financiers who rely on them. Our people work at source, from bases in seven African countries, and report to the client alone.

What we do
Much of the risk in buying minerals from Africa lies in facts that can be established but often are not: whether the supplier is the company it says it is, whether it holds the licence the deal needs, whether the material exists and is what the papers say. Nairank Global establishes those facts from the record and from the material itself, and sets them out in a report that a board, a bank or a court could follow.
Every engagement is measured against the Nairank Global Standard, our due diligence framework, and closes with a written recommendation.
