About Critical and Strategic Metals Hub
Facts checked against sources on . How we check facts.
Critical and Strategic Metals Hub is an information site on critical minerals. It compares the official lists of the United States (60 minerals), the European Union (34), Canada (34) and Australia (31), profiles 60 minerals, and explains the supply chains, prices, policies and recycling routes behind them. Facts are taken from primary sources such as USGS, statutes and government notices, every page shows the date its facts were last checked, and corrections are logged. The site's owner also runs EarthRarest, a supplier of nine metals, and the site says where that matters.

What does the site cover?

| Mineral profiles | What is this mineral used for, who produces it and where does it sit on the lists? | Minerals |
| Critical minerals | What makes a mineral critical and how is it scored? | Critical minerals |
| Supply chain | Where are the bottlenecks from mine to manufacturer? | Supply chain |
| Markets | How are prices set and what do inventories and contracts show? | Markets |
| Geopolitics | What do export controls, alliances and security policy change? | Geopolitics |
| Applications | Which industries depend on which minerals? | Applications |
| Recycling | How much supply can recycling provide? | Recycling |
| Projects | Which mines, refineries and recycling plants are on official lists? | Projects |
| Rare earths | The 17 elements, their prices, separation and magnets | Rare earth elements |
How are the facts checked?
Each number on an article page links to a primary document where one exists, such as a USGS Mineral Commodity Summaries chapter, a regulation on EUR-Lex, a Federal Register notice or a company filing. Where a figure could only be read in a press report, the Sources list says so. Pages show the date their facts were last checked. The data sources and methodology page describes the process in full.
How does the site relate to EarthRarest?
The site's owner also runs EarthRarest, a business that supplies gallium, germanium, hafnium, indium, rhenium, terbium, dysprosium, neodymium and praseodymium. Links to EarthRarest appear only on pages about those metals and on rare earth guides, in a labelled quote box. They do not appear on pages about official lists, policy or geopolitics. The EarthRarest prices on mineral pages are labelled as dealer list prices and are shown separately from market prices. The site does not give investment advice.
