What is the Rare Earth Directory?
The Rare Earth Directory is an independent reference to U.S. rare earth mines, projects and companies. It exists because the facts are scattered across filings, agency releases and company announcements, and the news moves faster than the details.
- One vocabulary"Producing", "development" and "exploration" each have one definition, used the same way on every page.
- Letters are not moneyGovernment support carries a status, so a non-binding letter is never read as a loan that closed.
- Sources on the pageEvery profile lists its sources with a type tag, so you can open the filing or the release behind a number.
- Conflicts are shownWhen sources disagree, the page shows both figures and says which is which.
The directory describes facts. It does not give investment advice, price targets or buy and sell opinions. See the editorial policy.

What counts as a mine, a project and a plant?
A mine produces rare earth material today, a project is a deposit being explored or developed, and a plant separates, refines, alloys, magnetizes or recycles. Each status has one definition, listed on the methodology page.
Can I trust a number on the site?
Each profile lists its sources with a type tag, a confidence grade and a verification date, and company-reported figures are labeled. The methodology page explains how facts are checked and where the directory's limits are.
