Editorial policy

All content on RareMetals.net is published by the RareMetals.net Editorial Team. These are the rules we follow.

Sources

• Production, reserves and annual prices come from the U.S. Geological Survey Mineral Commodity Summaries, using the latest edition.
• Company facts come from annual reports, quarterly reports and stock exchange announcements, not from press coverage alone.
• ETF facts (fees, assets, holdings) come from the issuer's own fund page and carry an as-of date.
• Export controls are described from the official announcements and dated.
• When sources disagree, we say so and show both figures instead of picking one silently.

One set of definitions

We use one classification across the site: light rare earths are lanthanum to europium (atomic numbers 57-63); heavy rare earths are gadolinium to lutetium (64-71) plus yttrium; scandium is grouped separately. Other organisations draw the line elsewhere (for example, some count samarium, europium and gadolinium as a "middle" group); our light vs heavy guide explains the differences.

Dates and updates

Every article shows when it was published and when it was last updated. Prices always show the date of the price, not the date you view the page.

No personal investment advice

We explain how markets work, what moves prices and which listed companies have exposure. We do not tell readers what to buy, how much of a portfolio to put into rare earths, or whether an investment suits them.

Independence and links

Some pages link to EarthRarest.com, a seller of physical rare earth metals with which we have a commercial relationship. Those links are marked and do not change what we write about prices or risks.

Corrections
